Low-temperature drying in the drying room means no more than 45 degrees. Low-temperature drying is similar to room-temperature drying. Compared with high-temperature drying, low-temperature drying requires a longer drying time. Low-temperature drying maintains the original quality of the material. , The price and cost are higher than high-temperature drying, and low-temperature drying effectively prevents mildew of materials due to weather. The drying room uses low-temperature drying during drying to retain the original fragrance and activity of the material and to ensure that the material can be completely dried, and the dried material has a good taste.
When the drying room uses high-temperature drying, the drying temperature is often greater than 40 degrees. The drying time is short, the cost is low, and it is not affected by the weather. The quality of the dried materials is inferior to low-temperature drying. Products dried at high temperature are often cheap, with high yields and high profits
Low-temperature drying and high-temperature drying should be used in combination in the drying room, and different drying processes should be selected according to different materials. Such as tea drying, we can use low-temperature drying.
low-temperature drying and high-temperature drying in the drying room are used in stages, which can be high temperature first and then low temperature, or low temperature first and then high temperature. Not only can the drying cost be reduced, but the drying quality can also be improved. Such as grape drying and blueberry drying.
