Energy-saving Tower Urban Domestic Grain dryer

Continuous Dryer Working Principle

The wet material is fed continuously to the first drying layer on the top of the dryer. It will be turned and stirred by rakes when the rake arm rotates and drop down to the outer edge of the large drying plate along the exponential helical line. The material will be moved from the small drying plate to its outer edge and drop down to the outer edge of the large drying plate underneath. Both small and large drying plates are arranged alternately so the materials can go through the dryer continuously. The heat medium can be saturated steam, hot water or thermal oil. The heat will be led into hollow drying plates from one end and come out from the other end. The dried materials will drop from the last layer of the drying plate to the bottom of the dryer and then moved by rakes to the discharge outlet. The material moisture will be removed from the exhaust outlet on the top cover. For the vacuum-type plate dryer, the moisture will be sucked out by the vacuum pump on the top cover. The dried materials will be discharged from the bottom layer. The drying capability can be improved if the dryer equipped with supplementary devices such as finned heater, condenser for solvent retrieval, bag dust remover, return and mix mechanism, draft fan, and etc.

Features:

1 Amount of air, heating temperature, time of material sticking on the belt and velocity of feeding material can be adjusted in order to obtain the best drying effect.

2 Equipment’s con gyration is very excellent. It can use the netlike belt washing system and cooling raw material system.

3 Hot air can be circularly applied, the energy is greatly saved.

4 Unique air dividing device, it makes hot air distribute uniformly; this can guarantee products’quality.

5 Heating source can be selected from steam, conducting heat oil, electricity, and coal furnace and oil burner
