Multilayer continuous type efficient grain microwave drying equipment

Abstract

The invention provides multilayer continuous type efficient grain microwave drying equipment. The microwave drying equipment at least comprises a rack and multiple layers of microwave drying systems mounted on the rack; each layer of microwave drying system at least comprises a feeding device, an independently-controlled microwave drying cavity and a conveying device; each feeding device is mounted at one end of the rack, and each conveying device is mounted on the rack and penetrates the corresponding microwave drying cavity; conveying directions of the conveying devices in all layers of microwave drying systems are the same or the conveying directions of the conveying devices in the adjacent layers are opposite, and the conveying devices are used for conveying to-be-dried objects fed from the feeding devices to the microwave drying cavities; and the dried objects obtained after drying are directly conveyed to a discharging opening or conveyed to the conveying devices of the next layer to continue to be dried. The multilayer continuous type efficient grain microwave drying equipment is high in space utilization rate, design of the multilayer independent cavities is more favorable for precise control in the drying process, operation is convenient, safe and reliable, and the grain drying quality is greatly improved.

Description

technical field [0001] The invention relates to the field of microwave drying, in particular to a multi-layer continuous high-efficiency grain microwave drying equipment. Background technique [0002] my country is the largest grain producer and consumer country in the world. Affected by natural conditions, the moisture content of grains in different regions is generally high when they are harvested. Their respiration is strengthened and energy exchange with the outside world continues, which makes it easy to reproduce microorganisms and pests, causing The food is heated and mildewed, which damages the food. According to statistics, the loss of my country's grain in threshing, drying, storage, transportation and other links after harvest is as high as 15%. At present, the problem of food security has been related to the overall situation of economic development and social stability. How to increase grain production and reduce food loss is imminent. [0003] Traditional grai...
