During corn processing, we need to adjust the moisture of corn processing end products. And the moisture may exceed the safety standard for storage. To prolong the storage period, we need to reduce corn processing end products moisture to avoid mildew.
To reduce corn processing end products moisture, we can use rotary drying machine, frying pot, screw propulsion moisture reduction machine and warm-air duct moisture reduction machine. The warm-air duct moisture reduction machine is more popular for its small floor space, low investment, easy operation, and excellent dehydration ability.
How to reduce corn processing end products moisture? The material enters into the vertical moisture reduction machine from the downward inlet, and is conveyed upward by the warm air. During this process, it is heated and the moisture is reduced. The main working mechanism is feed delivery pipe which contains preheating pipe and heating pipe. When the 0.1-0.2MPa steam is conveyed into the heating pipe, it will heat the air both in the feed delivery pipe and the preheating pipe. The air is mainly suctioned from the upward part of the preheating pipe and is heated to 56-60℃ in the preheating pipe. When the air enters into the feed delivery pipe with material, it is heated to about 90℃ to meet the needs of moisture reduction.
Then the cyclone separates the material which is dried from the wet air. The separated material enters into the air separator machine for cooling.
From the above, we can have a simple understanding about how to reduce corn processing end products moisture.
