Description
Technical Field
The invention relates to the technical field of biscuit cooling equipment, in particular to a wheat biscuit cooling device.
Background
The cooling mode after baking of the biscuit determines the important factor of whether the biscuit cracks, and the process characteristic of baking is to remove a part of water in the cooling, because the water content of the biscuit just taken out of the oven is about 8-10%, the temperature of the whole biscuit is high, so that the water evaporation can be continued when the biscuit is exposed to the air.
Generally, the change in internal stress is caused by the internal moisture distribution being uneven. For example, freshly cooked biscuits, if allowed to cool rapidly, the edges of the biscuit will first dehydrate vigorously, resulting in a dry, center-wet moisture gradient at the edges. After being placed, the water in the center gradually diffuses to the edge, so that the edge of the biscuit absorbs water to expand, the center loses water to shrink, and cracks are generated. Therefore, all factors which increase the evaporation of water too quickly can cause the moisture gradient in the biscuit to increase, the stress to increase and the crack to be generated. Therefore, on the conveyer belt, forced ventilation cooling or too fast water evaporation caused by natural temperature and humidity conditions in winter are easy to generate cracks, and especially hard and tough biscuits with low sugar content are easy to generate.
