Circulation-type grain dryer

Abstract

The invention discloses a circulation-type grain dryer. A transmission cylinder is vertically arranged in an aggregate chamber. A spiral blade shaft is arranged in the transmission cylinder through a bearing. A discharging port is fixed on the upper part of the transmission cylinder. Two transmission wheels are arranged above a material guiding groove, wherein one transmission wheel comprises a conveyer belt. Delivering plates are vertically fixed on the surface of the conveyer belt. A storage chamber is fixedly arranged above the material guiding groove. An opening is provided on the bottom of the storage chamber. Under the effect of a power system, grains in the storage chamber are continuously delivered out from the conveyer by the delivering plates arranged on the conveyer, and are baked by using a hot-air heating device. The conveyer moves continuously, such that the baked grains are delivered to the aggregate chamber through the guiding groove. With a corresponding transmission mechanism, a motor drives the spiral blade shaft to rotate, such that the grains are delivered to the storage chamber. Therefore, all the grains can be subjected to uniform heating circularly and sequentially by using the hot-air heating device. The more than circulation times are, the higher the grain dried degree is.

Description

technical field [0001] The invention relates to a drying technology, in particular to a circulation grain dryer. Background technique [0002] In order to preserve the grain for a long time, the moisture content of the grain must be kept low enough. Therefore, before the grain is put into the warehouse, the moisture content of the grain must be dealt with accordingly. At present, the drying of the grain mainly uses The following methods, one is to adopt the method of sun exposure; the other is to adopt the method of fixed drying bin, but both methods have the following deficiencies in use. First of all, the method of sun exposure is adopted, although The cost is low, but this method is limited by the weather and the site, so it is inconvenient to use; while the method of using the drying bin can not be restricted by the weather, but the one-time investment of the drying bin is relatively large, and at the same time, When the drying capacity of the drying chamber is small, i...
