A kind of high moisture grain storage method

Abstract

A high-moisture grain storage method, comprising a steel silo for storing grains, the steel silo comprising a cylindrical silo body, the top of the silo body is sealingly connected to a conical silo roof, and the silo top is provided with an outlet. The air outlet is communicated with an exhaust fan through a pipeline; the bottom of the steel silo is provided with a bottom plate for resting the rice, and the bottom plate is evenly provided with mesh holes, and the bottom plate and the bottom of the warehouse body form an air A mixing chamber, the air mixing chamber is communicated with an air supply pipe of a fan through a pipeline, and the air supply pipe of the fan is heat-transferred with a heat exchange mechanism of a heat pump; The top of the steel silo is provided with a feeding port and a distributor, and the bottom is provided with an outgoing auger. The grains are directly stored in storage without the limitation of water content, and do not need pre-drying treatment, which can avoid the mildew loss of grains caused by untimely drying in rainy weather.

Description

technical field [0001] The invention belongs to the technical field of grain dry storage, and relates to a high-moisture grain storage method. Background technique [0002] The safe moisture standard for rice storage in northern my country is 14% moisture content, more than 14% is called high moisture rice, generally not more than 18%, but the moisture content of fully mature rice grains harvested in sunny and low humidity weather in the southern region Generally in the range of 20%-30%, the moisture content of rice grains harvested in rainy or humid weather is even as high as 35%-40%. [0003] The national standard GB1350-2009 stipulates that the moisture content of indica rice used for purchase, storage, processing and transportation shall not exceed 13.5%. Indica rice with a moisture content of less than 13.5% (13.5%) is collectively referred to as standard moisture quality rice; moisture in the range of 13.5%-14.5% (including 14.5%) is collectively referred to as high-mo...

Problems solved by technology

The disadvantage is that most of the grain storage warehouses in our country adopt room-type warehouses (accounting for about 80% of all warehouse types), which are large in size and area, and the transportation machinery and equipment are difficult and seriously insufficient. In addition, they are restricted by the development level of other related technologies. It makes it difficult to meet the needs of large-scale practical applications; and because the drying process takes a long time, it is easy to appear the phenomenon of moisture stratification after drying, which is greatly affected by the climate, so it is necessary to choose a suitable period of operation; Replacing the previous one-by-one drying method is of positive significance for making up for the lack of drying capacity during the harvest season, reducing post-harvest losses and maintaining grain quality.
