Abstract
The present invention relates a vacuum grain drying tower. The vacuum grain drying tower comprises a drying tower, radiators, a heat-conducting pipe device, glide stirring devices, a discharge material storage device, a grain delivery pipe, a grain cooling cabin, feeding material storage devices, a material inlet, a discharge hole, a cooling fan, a heat source device, vacuum exhaust fans and ladder protection brackets. Heat energy generated by the heat source device radiates from the interior of the radiators inside the tower to provide the moisture in grains with enough heat. The grains are surrounded by vacuum negative pressure, so that the moisture in the grains is diffused to the surface of the grains by a pressure difference or a concentration diffusion difference, and the vaporization rate of the moisture is increased. The vacuum exhaust fans extract vapor quickly. Thus, the grains are continuously dried by passing through a preheating section, a tempering section, a drying section, a tempering section, a drying section, a tempering section and a cooling section, so that the grains can be quickly dried. The vacuum grain drying tower adopts such techniques as external heat preservation, internal heating, terminal circulation, lower-temperature drying, vacuum dehumidification and waste heat utilization, so that the energy is effectively saved, the drying time is shortened, and the processing cost is reduced. Besides, the use of low-temperature drying ensures that the plant activity of the grains is not damaged.
