Description

Technical Field

[0001] The utility model relates to the technical field of food production, in particular to a drying and cooling device for food production. Background Art

[0002] The drying and cooling device for food production is a special equipment used in the food production process, mainly composed of two parts: drying and cooling. In the food production process, the formed food needs to be dehydrated and solidified through a drying device to meet the expected taste and shelf life requirements. The food just out of the drying furnace has a high temperature. Direct packaging is likely to cause problems such as oil separation and packaging deformation, affecting the food quality and storage period. Therefore, the cooling device plays a key role in this link. It can quickly cool the high-temperature food to room temperature or near room temperature, facilitating subsequent packaging and storage. The main function of the drying and cooling device for food production is to efficiently dry the food to ensure its forming quality, and at the same time, quickly cool it to ensure the food quality and storage safety.

[0003] After retrieval, the text of the patent number "CN210076441U" mentions that "the utility model discloses a biscuit forming and cooling device for sandwich biscuit production, including two frame plates arranged in parallel left and right. Between the two frame plates, multiple connecting rods are welded. Above the two frame plates, two C-shaped air outlet plates are symmetrically arranged. The inner upper and lower surfaces of the air outlet plates are evenly distributed with air outlet holes. On the outer side of the air outlet plates, an air inlet pipe is arranged. Between the two frame plates and below the connecting rods, an installation plate is arranged. A first screw is used for the cooperation between the installation plate and the frame plates. Below the installation plate, two axial flow cooling fans are installed. Each cooling fan is separately matched with one of the air outlet plates. The cooling fan is connected with a cold air pipe. A hose is assembled between the cold air pipe and the air inlet pipe. A cold water tank is welded between the two frame plates; this product can be used in cooperation with an assembly line baking device, and the biscuits being dried can be cooled during the conveying process". When it is in use, it is used through an assembly line baking device, and the biscuits being dried can be cooled during the conveying process. However, when the above device uses the air cooling method to cool the biscuits, problems such as cracking or deformation caused by stress concentration inside the biscuits due to rapid cooling will occur. Moreover, when the existing biscuit drying device dries the biscuits, due to the non-circulation of hot air in its chamber, the inside and outside of the biscuits are not evenly dried during the drying process, which will cause uneven heating of the biscuits, and at the same time, excessive heat will cause nutrient loss or poor taste of the biscuits.

[0004] Therefore, we provide a drying and cooling device for food production to solve the above problems. Content of the Utility Model
