Description

Cheese drying device based on cheese hardness automatically regulated temperature Technical Field The invention relates to the technical field of cheese processing, in particular to a cheese drying device capable of automatically adjusting temperature based on cheese hardness. Background Cheese bars and cheese blocks are nutritional snacks suitable for children, and the base material of the raw materials is dry cheese. The dry cheese is produced basically by adopting a drying box to dry, large cheese is firstly torn into a strip or a small piece, the large cheese is spread in a tray and put into the drying box to dry, the dried cheese is dried for twenty hours at the temperature of about 50 degrees, the moisture of the dried cheese is reduced, the hardness is increased, and the method is suitable for subsequent cheese snack production. In the prior art, the heating mode in the drying box adopts electric heating, if gas circulation is not carried out, then the gas water content in the drying box is increased along with the increase of time, the continuous evaporation and separation of moisture in cheese are not facilitated, and if circulation is carried out, new air is continuously supplemented to replace original gas, then electric heating consumes a lot of electric energy, the electric charge duty ratio in the drying cost is very large, in addition, the existing drying box does not consider the change of cheese state in the drying process, only the same temperature is used for continuously drying, the excessive drying is possibly caused, the cheese becomes too hard, and the moisture is too low.
