Problems solved by technology

[0004] The volume ratio of the grain dryer refers to the ratio of the volume of the dried grain to the volume of the grain dryer. The volume ratio of the existing grain dryer is generally about 10%. The volume ratio of the grain dryer is too low. low drying efficiency

Abstract

A single-cycle grain dryer comprises a support (1), an outer roller (2), a shoveling plate device, a feeding funnel (7), an outer roller rotation device, an inner core cylinder (3), a conveyor (8) used for conveying dried grain and an air feeding module. A hot air inlet is formed in one end of the inner core cylinder (3), a set of ventilation ports are formed in a cylinder body of the inner core cylinder (3), and the outer roller (2) is provided with a grain inlet, a grain outlet and an air outlet. According to the provided single-cycle grain dryer, one-end air inflow is adopted in the air inflow manner, the manner that air is evenly distributed into a grain drying channel through an inner cylinder is adopted, a hot air inlet device is high in heat converting rate, and the drying effect is prominent after the grain dryer is inflated with hot air. A waterfall type shoveling plate is arranged on the inner wall of the outer roller and constantly overturns grain, the volume rate of the grain dryer is greatly increased and can reach 35%-40%, the grain drying effect is more ideal, and very high practical and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of grain drying, in particular to a single-cycle grain dryer. Background technique [0002] At present, the grain of the existing grain dryer is a living organism, and moisture is the condition for its survival. However, if the water is too high, it will induce the growth of insects and microorganisms, which will easily cause food heating, fermentation, deterioration and a decrease in germination rate. Taking grain as an example, the moisture content of grain is 25-30% when it is harvested, and it needs to be reduced to a safe moisture content of 13-15% as soon as possible during storage. my country's grains are harvested 1 to 3 times a year and need to be stored for several years. However, in the process of grain production and grain drying, natural drying is easily restricted by the influence of weather and sites. With the large-scale promotion and application of grain harvesters and the rise of large gr...
