3 Editorial Advertisement Time factor As the last month of the year, December is often used to take stock - privately, professionally and financially. In terms of finances, it is the hard facts and figures that provide us with information about the past year. In our private and working lives, however, soft factors, which can often only be assessed with difficulty, are also significant. One of these factors is time (and that can measured) which is nearly always calculated too tightly. Planning a new production facility or the restructuring of existing systems generally makes this situation worse. Planning offices such as WD & Partner, who specialise in the project management and engineering of new builds, extensions and conversions, can create time. The planners, drawers and engineers do not release owners from their business responsibility, but they do prepare decision-making in a way that allows quick, sound and current solutions to be found. In industrial baking technology, the trend is towards automated solutions which not only increase product quality, but also reduce staff costs. Zeppelin Systems complied with this requirement in the construction of a production system for wheat-based biscuits and pastries and Photo: o: GBT The proofer with multi level conveyor belts is especially suitable for products which have been separated. where the system builder was not only responsible for his core business from raw material acceptance to dough delivery on the line but also for the building design. There is a completely different sense of time in the Hudson Bread production in North Bergen, America. Preliminary stages lasting several hours, long dough proving times and processing lines not run at full capacity characterise the image of this industrial company and its hand crafted products. We would like to wish you a similar relaxed approach to time for next year. However, take time to pore over Backtechnik Europe first. The major advantage: you can read it in your spare time or at work. We would like to wish all readers a wonderful Christmas and a happy New Year.

8 8 IBIE 2013 Backtechnik-europe Positive atmosphere in Las Vegas Exhibitors and organizers look back on a successful IBIE which could mainly convince by competent visitors. With a representive booth Rademaker was in Las Vegas. Photo: Backtechnik Rademaker Rademaker displayed the complete manufacturing range, from laminating technology via dosing systems to the Crusto-bread-roll line with gentle dough discharge system to the interested customers. In the first place, the team of the Dutch plant builder, who has an office in Hudson, Ohio, was convinced by the visitors competency and their good resonance on the first three fair days. Compared to the previous trade fair, the visitors were clearly better tempered, especially the fair visitors from America, so that, at this time, Rademaker expects a similar involvement in three years. Certainly, the good organization in the forefield and the satisfying physical distribution in the halls contributed to this decision. WP Photo: Backtechnik The discussions at WP were characterized by a positive moode. From the first minute on, the WP representatives were busy with answering the professional audience s questions concerning the displayed machines. They were mainly focussed on the preparation plant Pane which can produce round or square rolls and breads. Just as well, the head machine Softstar that is especially suitable for soft dough with long dough rest time was represented to the customers in America for the first time. The visitors were also very interested in the plants manufactured by the youngest subsidiary Riehle. Many conversations with old and new customers took place in a good atmosphere between the companies. This is the reason why the WP group wants to strengthen its presence in America in the next years. Diosna The team of the Managing Director, Dr. Wolfgang Eißer, from Diosna welcomed many visitors who were especially interested in kneader solutions for medium-sized businesses and the industry. More and more, the very compact trade fair establishes itself as a meeting place of the baking industry segment for the USA, South and Middle America. A bit longer Industry solutions were very much in demand. opening hours would help to improve the many and intensive contacts. All in all, the representatives of Diosna had a positive impression of the atmosphere among the American bakers. This was a reason for the plant builder also to exhibit together with Rondo to the same extent in three years. The Reiserbooth was always very busy. Photo: Backtechnik Vemag In the American market, Vemag is operating under the name of the parent company Reiser and here, it is successfully represented in different segments of the baking technology. Whether the classical dough divider for bread, pizza lines, cookies or cakes - the applications are very wide spread. In all conversation with customers about the lines, a clear trend towards automation occurred at the fair. Quality, quantity, traceability, and hygiene are increasingly catchwords in the American market which have to be implemented and satisfied by the baking companies.
9 Backtechnik-europe Advertisement Image processing is increasingly in demand in the packaging industry. Photo: Backtechnik A&B Verpackungsmaschinen Compared to the last trade fair, the Managing Director, Björn Brandt, was very satisfied with the course of the fair and the contacts at this year s IBIE. The existing customers were all very positive tempered and are planning investments in the field of packaging. In this context, the visitors were enthusiastic about the technology of the camera-aided counter. Especially in the field of image processing, enormous technical progress was achieved during the last years, which was utilized by the packaging industry. Besides the conversations with their existing customers, the A&B team also welcomed many new customers. In both groups, the Managing Director was convinced by the quality of the conversations which exceeded his expectations considerably. Rondo Jerry Murphy, Managing Director of Rondo, USA, observed a clear increase in the visitors competency and number compared with the preceding exhibits. He held many talks with decision makers who expressed their view on the current market situation in a cautiously optimistic way. In addition to the Astec lines which are designed to meet the requirements on hygiene and food safety, the laminating machines were in the visitors focus to achieve the reduction of personnel costs. Murphy felt positive about the duration of the IBIE while the labeling and the radio communication in the halls could be improved. Photo: Backtechnik Cost reduction through labor and cleaning costs were much discussed topics. Photo: Backtechnik Bühler Group saw an important trend in the automation of the lines. Bühler The first positive impression in the forefield of the fair due to good organization and smooth erection of the exhibition equipment also continued during the trade fair. IBIE upheld its reputation as the most important industrial fair for the American market of backed goods. The visitors specialist competence was accompanied by a clearly noticeable spirit of optimism. Bühler sees an important trend in the automation of the lines. The European market has already relied on complex systems for quite some time because high flexibility is required for the plants. In America, however, the focus lies on simple systems with very high performance. Now, a change of thinking is taking place which is strengthened by new trends with the products.
10 10 Report Backtechnik-europe Processing technology from one source The Austrian plant construction company König delivered the complete processing equipment for several lines and for different products to Hudson Bread in North Bergen/America. The baguettes are made-up using the Artisan SFI which gently produces a continuous dough string. New York, the mega city at the American East Coast, is not only the trend-setter in the fashion and music segments but it is also the forerunner in the culinary area. Among others, this is mirrored by various upscale restaurants, cafes, hotels and casinos. Exactly this target group is supplied with highquality baked goods by the Hudson Bread company from North Bergen. They are produced under industrial conditions but always considering handcraft production methods. We consider ourselves as modern, industrially oriented bakery which is very well technically equipped. However it is our objective to produce something special. We can only manage it, as we see it, when we produce in an artisan way and produce products that have a traditional character, Raymond Million, vice president of operations, explains the company philosophy. Hudson Bread has implemented this target very well since its foundation nearly 20 years ago. In the mean time, the company is working 24/7 to supply fresh goods to the large number of customers. Approximately kilos of dough are produced every day and processed to become bread and small baked goods. With this, Hudson Bread relies completely on the relationship between König, HB-Technik and Miwe, this includes all machines from processing, to the proofer and ovens. Mixer In the dough making line, Hudson Bread is working with four mixers. With this Ray Million uses three twintwist mixers. All machines are equip- Photo : Backtechnik

Right photo: Due to its accurately calculated geometry, the dough is intensively kneaded in the intake zone and relieved in the outlet zone of the tool. ped with movable mixing bowls which allow the fast processing of the dough and the batch can be emptied by a tilting hoist. The serial design with two mixing and two bowl rates guarantees optimum adaptation to the recipe. The company-own recipes can be saved in the freely programmable control via a touch panel. The mixer head rises and lowers hydraulically whereby it closes the bowl well when it is locked. In this way, no flour dust can get out. When the bowl is engaged, the kneader locks the hydraulic clamp lock and presses it against the friction wheel which drives the bowl. The tool of the spiral kneader has a large working radius and always reaches just to the wall of the bowl. During each rotation of the tool, mixing and kneading processes overlap in a controlled way. With the increasing speed of the tool and the bowl, kneading will be intensified and more energy will be introduced in the dough. In case of the twin-axis kneader, the two screw-shaped kneading tools are very well adapted to each other. In this process, the inner tool guides the dough continuously from the inside to the second tool to be actually kneaded. The tools which have special windings and are arranged to each other in an optimum angle bring the kneading energy gently into the dough while pulling and folding it. Compared to the spiral mixer, the kneading times are often shorter which results in a lower dough temperature and a shorter dough cycle. After kneading and resting, the dough is then transported to the plant. There, the bowls are moved into the bowl hoist Hercules. During the whole lifting and tipping process, the mixing bowls are safely locked in the fixing brackets. The wide tipping angle guarantees the complete emptying of the bowl. If the dough includes rye, or is soft and sticky, the scraping device is used to support the emptying process.

It forms a defined dough string by means of gravity which is then portioned using a slicer. Mainly, the system consists of a cylindrical, non-stick coated stainless steel dough hopper of 300 litres capacity which is slightly tilted and it slowly rotates while it is placed on bearings in the top of the machine. The bottom of Photo : Backtechnik Facts Hudson Bread DBA Prestige Bread Co.

If now the tilting hoist fills the dough in, a dough ring is formed in the lower part of the hopper around the taper and forms the first step of the dough string. After the plant has been switched on, bottom, taper and dough hopper start to rotate with the same speed while the two last mentioned parts are coated by means of a finely adjustable oiling unit. Now, the lateral moving function of the bottom disc will be started. In accordance with the desired dough weights, or the required optimum string width, the disc is displaced below the hopper and forms a more or less wide semilunar open section between the hopper edge and the bottom disc through which the dough can flow driven by gravity and with this, it forms the beginning of the dough string. Then, it falls directly on the floured transfer disc which turns with the same speed of the before mentioned machine components, so that the string cannot be pulled or pressed, i.e. it runs out steadily. A pick-up conveyor is installed at the height of the turning point of the transfer disc whose speed is synchronised with the speed of the other plant components, and it picks up the dough string and leads it to the electronic weighing unit with belt weigher. If the dough end has reached the selected weight, the electrical guillotine will be actuated and the dough piece is separated with gramaccuracy, whereby the computer control automatically calculates and compensates the belt speed during the weighing process. In addition, two laser sensors are continuously scanning the width of the dough string, so that, depending on the current dough consistency, always the optimum string thickness is ensured by automatic changing of the semilunar cutting opening. If, however, larger weight differences occur, perhaps at the beginning of a new dough batch, or when the last dough residue leaves the hopper, an acoustic signal will be triggered. Then, the dough pieces run over the height-adjustable discharge belt and are led to the manual or machine processing where rounding units, intermediate proofer and long roller are at the employees disposal in the production department. Hudson Bread also produces a large variety of products on the Artisan SFI machine which continuously and gently produces a dough string. At first, the dough sheet is levelled to achieve an equal height using several twin-rolls and stamp mechanisms. Depending on the configuration, one or two satellite roller heads are used in the plant supported by the transversal roller. Individually adjustable longitudinal slicers cut the dough sheet into even strips before the guillotine cuts the pieces
13 Backtechnik-europe Report 13 further. Attachable modules, e.g. rounding station, long rolling station, moistening and seeding unit and other easily changeable tools ensure the high variability of the plant. A pull-off unit pulls the products then onto the baking trays or other proofing goods carriers. Another line is designed for the manufacture of small baked goods. In this process, the dough is filled into the hopper of the Industrie Rex first. The dough dividing and rounding machine is the biggest representative of the Rexfamily and reaches an hourly capacity of 36,000 pieces. In this head machine, dividing and rounding are separated and are performed by two independently working areas. In this machinery, the rounding pressure and its intensity can be adjusted optimally depending on the recipe. Then, after the Industrie Rex, the Combi Line follows. Using this plant for small baked goods, a wide product range of the small baked goods can be covered. Stamping station, slicer and shaping station ensure the required variability which is required by Hudson Bread to implement their concept. Summary Starting with the dough making-up department to the conveying system for the products in the proofing room, Hudson Bread is using technology made by König. Using the machines and plants made by König, we can implement our concept of an industrial production with artisan character very well, Million explains their decision on this provider for the make-up line. In addition, he sees advantages for maintenance and service and for the training of the employees. Furthermore, he is convinced by the robustness of the plant which is in operation for twelve hours on each day of the week. Another reason for the durability of the machinery certainly is that it is not run at its capacity limits. We do not produce under full load. This does not only go easy on the machines but also the dough, and this is very important to us, Million completes. The success proves Hudson Breads right. The company is the leader in the supplier business for high-quality baked goods in the area around New York. We want to be the best ones in our field. Therefore, we always focus on our internal structures that we permanently adapt to our growth, Mariusz Kolodziej, the Managing Director, finishes our interview. Gregor Vogelpohl Advertisement

18 18 Report Backtechnik-europe A well-oiled team The Vandemoortele dough plant in Dommitzsch has been working successfully with the lines from Mecatherm, a machinery and industrial equipment manufacturer, for years. W hen the takeover took place in Dommitzsch in 1991 of what was once a combined oil and margarine company, no-one could have guessed how well the factory would do: neither the Vandemoortele Group, an investor, which can look back at over 20 years of success; nor the current Managing Director, Friedhelm Günther, who has been there from the outset loyally committing over 40 years of service and accompanying the change from a margarine factory into a modern dough plant. After the takeover in 1991, the new owner from Belgium resolutely invested in the area of deep frozen bakery products just one year later. One year on and the pretzel dough product line and first bread production line went into operation. Margarine production continued in parallel until the end of 1993 when it was finally relocated to the former Dresden margarine factory. Günther and his team met the challenge head-on, thus contributing significantly to this positive development. In fact, the original count of 58 employees has now risen to 190. The production volume is also impressive. A non-stop kneader supplies the two Bloc HP2 processing systems from Mecatherm. Photo: Back Technik Backtechnik chn k 04/

MIddle photo: Production is with 2,000 by 800 millimetre trays with 25 troughs; the dough pieces are positioned precisely within these. Right photo: Upstream of the proofing chamber, the trays from both processing systems are merged. 23,000 tonnes of finished products are currently produced a year, on five production lines. One of these is a Megaline II from the French machinery and industrial equipment manufacturer, Mecatherm. The system comprises the block for dividing and shaping the dough pieces, the final proofing tunnel, the automated cutting device, the oven, cooler and freezer, and all elements for conveying, handling and monitoring the tray cycle. Processing Dough preparation and processing in Dommitzsch takes place in its own designated hall. A non-stop kneader supplies two Bloc HP 2 processing systems with dough by means of conveyor belts. In the Bloc concept, Mecatherm has combined the functions of dough division, resting, shaping and the automated placing of the dough pieces. Every line has a dough divider equipped with two hoppers. The kneader dispensing belt goes left or right depending on which of the four hoppers has signalled a request. Another belt above the hoppers ensures that the dough is transferred correctly. The individual pieces of dough are then shaped on two tracks before merging back into one by the rolling mill. The dough pieces are then deposited on the 2,000 by 800 millimetre moulded trays which have 25 troughs. The line itself runs on a tray system, but can produce different items. The portfolio ranges from baguettes weighing around 300 gram to six rolls each weighing 40 grams, which can be placed in a trough. The filled trays then move to a switching point where both lines are merged. This is where the products are transferred to the proofing chamber. Proofing, baking and freezing The incorporated proofing chamber is designed for a total of 448 trays. The dough pieces rest for around two hours at a temperature of about 25 degrees Celsius and 80% humidity. The trays are guided vertically through the individual zones; this is typical of many Mecatherm applications, regardless of whether these concern climate control or oven technology. This allows them to be separated more easily; different settings, such as temperature, humidity, or steam, can be adjusted to the specific products. This also applies to the last zone of the proofing chamber, where drier and cooler air prevails. Stiffening the dough pieces has two major advantages; on the one hand, the cutting robot blades can process the products better and, on the other hand, it improves steam condensation on the product. A cutting pattern is stored in the cutting robot control system for every item. Following every cut, which may be diagonal, straight, overlapping or a combination of options, the blades move to a water basin. Here, they are cleaned and any residues are removed. To

All elements feature their own burners and steamers, which enables an individual profile to be created for every zone.

After the next cycle in the second position, the air flow is reversed to allow for even heating of the tray. Like the trays, the steam is also directed from the bottom up in the first chamber. This is achieved by the vent at the top of the oven. The air velocity can be varied depending on the vent opening. In the last zone, the products finish baking before moving through the cooling and freezer zones. Both systems are designed for 144 trays and work, like the proofing chamber and oven, according to the paternoster principle. In addition to the components described, Mecatherm is also responsible for the conveyance, handling and monitoring of the tray circulation. As high standards demand, the products are not only counted prior to being packaged, but also quality controlled according to geometry or volumes. Summary Since the takeover of the combined company for oil and margarine in Dommitzsch in 1991, a lot of things have been done properly. One of the factors to success is indubitably continuity, which is evident in many areas. For example, HR policy is worth mentioning in this respect. Managing Director, Friedhelm Günther, and the Quality Officer, Inge Lingel, have worked in the factory for over 20 years; they exemplify the extremely high value in terms of lengths of staff service. Continuity is also represented by the flour suppliers. The main raw material has been supplied by the mills in Dresden and Alsleben for over 20 years. Both partners are well coordinated; this is reflected in the defined flour quality, which is optimally suited to the factory production lines. This is an essential criterion for good product quality and excellent system efficiency in the factory. Furthermore, continuity also applies to the selection of
