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, soybeans, 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 grains and oil processing factories.
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.
