Problems solved by technology

The advantage of the cooling roll is that the heat transfer coefficient is large, the cooling efficiency is high, and the temperature of the dried product after cooling can be guaranteed to meet the requirements; the disadvantage is that the device is complicated, the cost is high, and the internal water-filled cooling roll is unstable, and the running speed of the dried product is synchronized. Defects cause scratches on the surface of the dried product
There are also some equipment with low requirements that adopt forced air cooling, and use the fan to drive the air in the environment to blow the drying object to achieve the purpose of cooling. The advantage is that the device is simple, and the disadvantage is that the heat transfer coefficient is low, and the speed limit of the drying object is large. , the temperature is still higher than the ambient temperature after cooling, and shrinkage and deformation cannot be completely prevented; the surface of the dried object is easily polluted by a large amount of dust in the ambient air
