Multi-stage drying equipment for grain quality guarantee

Abstract

The invention discloses multi-stage drying equipment for grain quality guarantee in the technical field of agricultural production. The multi-stage drying equipment comprises a drying box, a vibratingmechanism, a turnover mechanism and a drying mechanism. According to the multi-stage drying equipment for grain quality guarantee, a feed hopper adds grains to be dried to a placing frame of a firstdrying cavity, reciprocating vibration of the placing frame in the horizontal direction is achieved through the combined action of a first spring, a second spring and a cam, and therefore grains placed on the placing frame are rapidly spread on a net plate through vibration; when the drying mechanism works, a hot air blower continuously conveys hot air into a third drying cavity through a third air pipe, then the hot air enters a second drying cavity through a second recycling pipe and a second air pipe for drying, and the hot air enters the first drying cavity through a first recycling pipe and a first air pipe again for drying; and after the grains in the first drying cavity are dried for specified time, the vibrating mechanism and a baffle plate rotate through the turnover mechanism, and the grains enter the placing frame of the second drying cavity.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a multi-stage drying equipment for grain quality preservation. Background technique [0002] Grain refers to the general term for various plant seeds in cooking food, also known as "grain", which is rich in nutrients, mainly protein, vitamins, dietary fiber, fat, etc. [0003] In ancient times, walking on the road was called food, and stopping living was called food. It is also commonly referred to as raw grains and finished grains such as cereals, beans, and potatoes for consumption. The food concept of the Food and Agriculture Organization of the United Nations (hereinafter referred to as the FAO) refers to grains, including wheat, beans, coarse grains and rice. [0004] Among them, wheat includes wheat, barley, highland barley (yuan wheat), rye, and oats; beans include soybeans, adzuki beans (red beans), and mung beans; rice includes japonica rice, indica ric...

Problems solved by technology

[0008] When the existing grain is stored, it will be dried first, so as to ensure that the grain will not be moldy and deteriorated during storage. The traditional grain drying method is to dry by spreading the grain, but this method is slow in drying speed and the grain is spread out. It needs to occupy a large area, and it is inconvenient to dry; now there are also drying devices for fast drying of grain, and the drying room can heat and dry the grain through the hot air generated, and at the same ti...
