The bakery plant manufacturer FRITSCH has redesigned the LAMINATOR 300. The sheeting line is even more flexible and gentle in dough treatment.

The demands on dough processing are growing. Systems are in demand that can be used flexibly and treat the dough as gently as possible. When forming a dough sheet, it is crucial to preserve the already developed dough structure, even when processing large quantities and demanding doughs.

The LAMINATOR 300 is a dough sheeter for automated production, which ensures an even and continuous dough sheet. This has now been further redesigned by FRITSCH in the area of dough feed and control. The system is now even more flexible and gentle in the treatment of dough.

From puff pastry, croissant, short and Danish dough types to soft dough types required for rustic baked goods such as baguettes and Ciabatta: The LAMINATOR 300 processes a wide range of different dough types. The system is constructed in three sections, which can be combined as desired. Depending on the system configuration, the LAMINATOR 300 can be used as a block machine or as a continuous line for dough sheet production.

The universal version (Section 3) handle the soft the dough types. This system produces a continuous dough sheet with a capacity of 200 to 1,000 kg, which is then further processed to the respective end product.
Alternatively, the line can be used to produce dough blocks with a capacity of up to 1,500 kg of dough per hour. These blocks can then be cooled for a certain period of time before being formed into precise shapes and products on a FRITSCH MULTILINE (‘sheeting line’) and a ‘make-up line’. Both possibilities can also be combined in one line.

Dough sheet processor now available for section 1

Now and in the future, the dough can be discharged via the dough sheet former DS (3 roller former). It is also possible to combine the LAMINATOR 300 in section 1 with the low-stress dough sheet processor TBP in combination with a satellite head. Using five rollers TBP, all doughs are gently rolled and formed into an even, continuous dough sheet. The TBP is suitable for doughs with a dough yield of 145 to 175, making the entire process even gentler (‘soft processing’). According to information from FRITSCH, it has therefore been possible to dispense with the cost-intensive intermediate cooling at the appropriate room temperature in various projects.

Technical Data Laminator 300

Table width: 700 mm
Net dough sheet width: max. 600 mm, infinitely adjustable
Belt speed: 0.6 – 6 m/min on exit belt section 3

Dough block production: up to 1,500 kg/h
Layers: 16 – 144 fat layers


 The LAMINATOR 300 can now be combined in section 1 with the TBP dough sheet processor with a satellite head. This makes the entire process gentler

Shaping of the butter sheet: improved flow properties

Once the dough sheet has been formed, adding the fat is another crucial step. A fat pump is used to convey drawing margarine or butter and apply it to the dough sheet in an even layer. The company’s new fat pump improves the flow properties of the fat – especially in the case of butter – and thus produces an improved butter sheet. A water separator can be installed as an optional extra. By means of the sandwich folding system, an even dough-fat sandwich is produced.

Even after the sandwich folding, the company continues its SoftProcessing principle. This technology is mainly based on the satellite head developed by FRITSCH. This allows the dough to be exposed to minimal stress. The careful rolling of the dough sheet ensures that the structures built up in the dough survive these important steps without damage.

The dough is then folded. The folding channels are coated to repel the dough. Output and folding width are electronically controlled so that the dough sheet is deposited in evenly folded layers. The dough sheet is thus laid in four to twelve layers.

Cascading control

In addition to the gentle processing of the dough, the company places great value on high system availability and ease of operation. An automatic, permanent cascade control system now makes operation even easier. The tedious calculation of individual percentage values is no longer necessary. Due to factor chaining, manual input is no longer required for individual drives. With the LAMINATOR 300 control system, setting the output and number of layers is all that is needed. All subsequent adjustments to the folding width or number of layers are calculated automatically.


Control system: Detailed views are displayed in 3D

For example, if the operator wants to reduce or increase the number of pieces at short notice, there is no need for manual changeover. The control system calculates the values directly through factor chaining. This avoids errors and saves time.

According to FRITSCH, the new control system also has a lot to offer optically. Thanks to its modular design, the various views of the plant have been redesigned in 3D format. In addition, the new control system allows all users to be created individually, with specific rights.
