Production Capacity


Mixed-flow tower grain dryers absorbing the advantageous technique of foreign advanced models, are designed and manufactured based on our years of experience and local conditions. The machine is very adaptable to different grains and surroundings, which can be used for drying rice, soybean, wheat, sorghum, rapeseed, corn and oil crops. The rice drying machine uses clean hot air as heat medium, in other words, hot air drying. The heat source is a coal hot air furnace or oil hot air furnace .This drying machine can realize continuously drying operation and outdoor installation, which is suitable for the grain storages and grain and oil processing factories.


Working Principle

Mixed-flow tower grain dryers make use of the clean hot air as heat medium to dry grain. The interior of dryers is composed of angular ventilation boxes, which is arranged in a staggered arrangement. The angular boxes are filled with grains flowing downward. The hot air enters the intake angular box through the grain layer, and passes through the grain layer from above to below. The exhaust gas is discharged through the exhaust angular boxes. The hot air and grain flow concurrently and countercurrently with gran flow, which is also called mix flow. When the hot air passes through the grain layer, it has heat and moister transfer with gains:

Hot air will transfer heat to the grain, raising the temperature of gain. The contained water evaporates into the air and becomes waste gas. The dried grains flow downward to the balancing section. After passing through the balancing section, the grains reach the balance point of temperature and moisture interiorly and exteriorly, achieving the uniform moisture reduction. Then the grains enter the cooling section and get cooled to storage temperature. Eventually the dried materials will be discharged through outlet.

Performance characteristics

Fast drying and high efficiency

Mixed-Flow Tower Grain Dryer has the characteristics of high temperature resistance and can dry raw material with high temperature hot air.

Low consumption and low cost

Mixed-Flow Tower Grain Dryer has strong anti-overload capability, large processing capacity, low material consumption and low drying cost.

Low wear and long life

adopts "centering roller device", which makes the roller and roller ring have linear contact, which greatly reduces wear and power loss.

Low load, no block

new feeding and discharging device, which eliminates the blockage, discontinuity, unevenness and returning of rotary drum dryer, and reduces the load of the dust removal system.
