Drive technology made by SEW-Eurodrive ensures the movements in the machines of TAL B.V. in Coevorden. These machines process every kind of pastry dough from dough lump to all desired cookies’ shapes. The demands made upon dough processing are just as strict and different as the taste of the consumer in the store.
TAL uses drives from SEW-EURODRIVE for its dough processing machines.
TAL B.V. is located in the spatial Coevorden, a town in the South-East of Drenthe. The logo on the building’s facade attracts the attention immediately: white round letters on a dark blue background. Jeroen van Vlimmeren has been the managing director for one year now, and tells us which emotion these letters want to radiate since the firm’s founding in 1982: Simplicity, reliability, modular design, multi functionality and surveyability. Also TAL’s dough processing machines are devised, designed and built on the basis of these qualifications.
Full package for confectionery
Jeroen van Vlimmeren is interim manager at TAL. His background – interested in electrical engineering from childhood, a wide experience in the pastry and packaging industry and years of self-employment – constituted a solid basis to get started at TAL. His goal: Put the company on the map more explicitly with a "full package for confectionery". Jeroen van Vlimmeren: "In the years after its establishment TAL particularly made a name as a mechanical repair centre.”
The then director-owner bought up used bakery machines, overhauled the equipment and adjusted it to the specific dough to be processed. The result was a large variety of robust machines with names like form roller, wire cutting device and paste dispenser, but an increasing lack of structure and efficiency. In order to be profitable, the company had to change course.
One of the solutions arose on the shop floor, namely provide a modular machine structure. This could shorten production time, uniformize machines to easier complement the customer’s production line and make maintenance easier and cheaper. It’s a strategy with which TAL focuses primarily on confectioners in small and medium-sized enterprises that want to automate their production process. Van Vlimmeren: "The result is that they now buy a basic machine that through options, such as a knives cutting module or a baking trays transport, can grow with the company, taking into account their own recipes or the structure of the dough".
Variety of machines
At the IBA in Dusseldorf, one of the largest trade shows for the bakery industry, TAL introduced its latest thread cutting dispense extruder, followed by a drum threading machine on the Bakery Days 2010 in Amsterdam.
The product range also consists of form rolling machines, spreaders (providing biscuits with decoration, such as flaked almonds or ground coconut) and guillotines (for cutting off dough strands or dough slices). All modular-aimed at a belt with a width of 400 to 1000 mm for plate transport, which is slightly smaller than that of the competitors (often > 1000 mm), but also cheaper.
Drum threading machine
The drum threading machine has a stainless steel hopper for the supply of the dough, feeding it into the food rolling mill, consisting of rollers having longitudinal grooves for grip on the dough. The rollers are driven by squirrel-cage induction motors that are mounted on the outside of the machine. The dough is dosed in the food rolling mill and then pressed in the cylinders. As the drum keeps rotating, the knife cuts off the excess dough and the pistons press the dough out. The dough pieces that stay on the pistons are removed by means of a thread cutting arm and put on a baking sheet or steel link. The resulting products are equal in shape and size.
The SEW components that are applied in the dough extruder are a MOVI-PLC® Advanced, a DOP (drive operator panel), six frequency controlled MOVIMOT® drives with six fieldbus modules.
Form rolling machine
The form rolling machine features four SEW geared motors with built-up MOVIMOT® frequency inverters, which are controlled by two decentralized MOVIFIT® units. A MOVIFIT® has an integrated MOVI-PLC® for control of the machine. The second MOVIFIT® is connected through the SEW system bus. The SEW control panel is connected to the MOVIFIT® via Ethernet.
In the old situation the form roller had a switch cabinet and an operating cabinet. By applying the decentralized frequency inverters and decentralized intelligence, the complete switch cabinet could be left out, for only the operating cabinet to remain. This makes the control more transparent, while also saving significantly on the wiring of the form rolling machine. It is also now possible to remotely connect with the control and the frequency inverters via Ethernet.
Quote: Jeroen van Vlimmeren, interim manager
Our choice for SEW-EURODRIVE drives is based on our knowlegde and experience from the past. We prefer one motor brand of a proven quality.
"We prefer to use only one brand of motors of a proven quality. A detail, but an important one, is that SEW’s recognizable blue grey color fits well with our corporate color and contributes to the sound appearance of our machines.
An important substantive argument was SEW’s decentralized control concept (MOVI-PLC®). The connection technology of the motor on which a frequency inverter is integrated, ensures a swift installation and start-up.
It also ensures user friendliness as to diagnosis and maintenance, for example when replacing the electronics. The decentralized concept meets the three main criteria for decentralized drive systems: it's modular, flexible and cost effective. As a matter of fact we simply have no reason not to work with SEW drives!"
