[0005] Operation method of quality-preserving energy-saving drying technology
[0006] 1. High temperature drying method: hot air temperature 25-105℃
[0007] In the body of the grain dryer, there are 2-30 rows of vertically arranged grain drying cooling channels, air ducts and waste heat ducts. The cooling channels, air ducts and waste heat ducts are arranged in sequence and combined into a row. The air ducts are equipped with exhaust gas chambers, In hot air room and cold air room, the drying and cooling channels are on both sides with ventilated screens. The drying and cooling channels are divided into upper, middle and lower sections. The upper section is the waste heat drying section, the middle section is the hot air drying section, the lower section is the cooling section, and the upper end of the drying cooling channel is On one side is the exhaust gas chamber corresponding to the waste heat drying section, the hot air chamber corresponding to the middle hot air drying sect...
