The dough is entering the hopper and is
being pressed by a corrugating roller/ cylinder into a cylinder with
engravings. By pressure the engravings are filled and with a knife excess dough
is cut of the roller. A belt is being used for extraction of the dough, the
belt is of a specific kind and a roller is being used to make sure sufficient
pressure is there to facilate this extraction.
Here we have again a hopper and depending on the machine and for which type and
kind of other products the machine can be used we have either 2 or 3 feeding
rollers they fill a die plate that is being cut by a wire.
A depositing machine can be exactly the same as the wirecutting machine and in
some cases feeding rollers can be exchanged to use the machine for e.g. more
liquid products, such as batters for cakes.
Another kind of depositing is done by volumetric, this finds it’s way more in
batters and fillings.
- Extrusion and Co-extrusion
Some extrusion machines are similar to the wirecutting and depositing machines,
but technically extrusion implies that each depositing nozzle is individually
fed. This feeding is mostly done by a
screw. In baking it is quite simple, in other industries pressure and
temperature play a vital role in this to create the final product.
