Drying equipment for grains and drying method thereof

Abstract

The invention discloses drying equipment for grains, belongs to the technical field of grain processing equipment and solves the problem that grains are prone to stacking and therefore are insufficiently dried in the process of drying. Key technical points of the equipment include: the equipment comprises a material storage tank body, a drying tank body, and a rotary drying assembly; the materialstorage tank body is installed above the drying tank body; and the rotary drying assembly is installed inside the drying tank body. The invention further comprises a drying method of the drying equipment for grains. The drying equipment is composed of the material storage tank body, the drying tank body and the rotary drying assembly and is for sufficiently dispersing the grains; and in the process of falling, grain granules are in sufficient contact with hot air which circulates and flows from up to down, so the grain granules are sufficiently dried. Grain drying operation is realized in a way that the rotary drying assembly is initiated to disperse the grains and the grains are dried in the drying tank body, the operation is convenient and rapid, and the equipment is applicable to graindrying.

Description

Technical field [0001] The invention relates to the technical field of food processing equipment, in particular to a drying equipment for grains and a drying method thereof. Background technique [0002] The moisture point after the grain is harvested is very important for its commercial or planting use. As we all know, when the temperature and humidity conditions in the food environment meet the growth and reproduction of microorganisms, mildew will occur. That is to say, moisture and temperature are two important factors for the reproduction of molds and other microorganisms in grain (ie, grain mildew). Under normal circumstances, controlling the moisture of the grain below the safe moisture may prevent the grain from becoming mildew. Therefore, grain drying equipment is often used in grain storage and processing. [0003] At present, the method of reducing grain moisture is spontaneous combustion and drying. In the main grain production areas, due to the large output and ins...

AI Technical Summary

Problems solved by technology

In the main grain producing areas, due to the large output and insufficient drying space, the moisture in the grain purchased by the grain depot often exceeds the safe moisture content, which is the main factor causing the grain mildew in the grain depot, especially when the grain purchase period is catching up with continuous cloudy days. So; in addition, even if the moisture content of the grain does not exceed the safe moisture content when entering the warehouse, due to spontaneous combustion and moisture return, the grain entering the warehouse needs to be dried regularly to ensure that the grain does not go moldy. Due to the limitation of the drying place of the grain warehouse, the Grain often cannot be dried on time, resulting in grain mildew in the grain depot

[0004] At present, there are some grain drying equipment on the market, but they are all grain dryers with relatively single functions, and they are not suitable for processing a large amount of grain that needs to be dried. In the process of grain drying, whether it is horizontal drying The equipment is still a vertical drying equipment, and the grain is easy to accumulate in the drying part. The internal ventilation effect of the accumulated grain is poor, and it is difficult to turn over. When drying, it cannot be in contact with the air used for heating, and it takes a long time to dry. The drying effect of grain is poor, which is not conducive to saving energy consumption and cost, and the efficiency is also low
