Those who are not "professionals" might taste a biscuit without paying attention to the fact that it often has small holes. But for a biscuit manufacturer those holes are not always dictated by aesthetic. In fact, during cooking biscuits and crackers develop and assume an open and light structure. This is because with the cooking process in the oven the humidity in the dough comes out of the product. Now if this steam finds a way out through these holes, our biscuit will have an even surface, essential above all for the automatic packaging of the biscuits and the stacking. Otherwise, if the steam cannot escape, we are faced with structural problems of the product, in particular "checking" phenomena and / or bubbles on the surface of our cookies.
The presence of the docker pins in the moulds is therefore essentially dictated by one or both of the following factors:
a) Indispensability: if they need to completely pierce the biscuit for cooking needs on steel band ovens thus avoiding the "craters" on the underside of the biscuit and the bubbles on the top of the biscuit. Also important to prevent the biscuit from falling out of the cavity before reaching the band causing a breakage or deformation of the product.
b) Decoration: if they have a pure aesthetic function: normally, in fact, with cooking on a net oven band they are not indispensable and if they are present they have a purely decorative function.
Errebi Technology's attention to detail could not fail to focus on the research and development of this small detail that is part of the mould. Height of the docker pins (which differs between a rotary moulding roller and a rotary cutter), arrangement and configuration on the biscuit, material (stainless steel or plastic material), profile of the docker pins and radius, half-conic, flat, rounded head, etc. are some of the fundamental elements to be taken into consideration according to the biscuit to be developed.
To complete its production, Errebi Technology has now its own internal production of docker pins with automatic insertion of the same on the moulds, to guarantee accuracy and precision both in the application and in the height of the docker pins. This is thanks to the investment in computerized machinery that allows these processes. In Errebi Technology we know that detail should never be underestimated and it makes the quality difference of a product!
