Solar heat-saving cycling type grain drying equipment

Abstract

The invention belongs to the technical field of grain drying and provides solar heat-saving cycling type grain drying equipment which comprises a conveying device, a solar hot water heat collector, a solar air heat collector, a left box body, a main box body and a right box body, wherein the conveying device can be heated, and the left box body, the main box body and the right box body are connected together. A drying cavity is formed in the main box body. A first feeding hopper is connected to the upper side of the main box body. A plurality of air-permeable drying beds are arranged in the main box body. The conveying device conveys the grain into the first feeding hopper while drying the grain so that the grain can enter the drying cavity and sequentially pass through the drying beds arranged from top to bottom. The drying beds are used for drying the grain, and the lowermost drying bed is used for outputting the dried grain. The solar air heat collector is used for outputting dry hot air to the bottom of the drying cavity, and the dry hot air is exhausted from an air outlet in the upper side of the main box body along with vapor evaporated from the grain. Adjusting mechanisms for adjusting the inclination angle and heights of the drying beds are arranged in the left box body and the right box body. The solar heat-saving cycling type grain drying equipment can evenly dry the grain, the grain is sufficiently dried, and the drying efficiency is high.

Description

technical field [0001] The invention relates to a drying device, in particular to a device which utilizes solar energy to supply heat to dry grains. Background technique [0002] Grain needs to be dried from harvesting to storage. It is especially important to reduce energy consumption and pollution. It is especially important to continuously improve the productivity and quality of grain drying equipment. Most grains are heat-sensitive grains. Improper selection of drying process or parameters is likely to cause bursting, which in addition to affecting In addition to drying efficiency, it will also directly affect the broken rice rate during grain rice milling, thereby affecting the rice yield, and then affecting its yield, quality and economic value. In rural areas, the grains are generally placed in tanks to dry, or the grains are placed on the ground to receive the sun’s rays to achieve the purpose of removing moisture. In doing so, there are usually the following disadva...
