Method for long term storage of grain without deterioration and equipment thereof

Abstract

The invention relates to a method for prolonging storage tenure of grains and bean grains to prevent deterioration, and equipment thereof. The equipment comprises a grain store, wherein the grain store can ensure vacuum degree and can be sealed; a vacuum pump assembly is arranged outside and communicated with the grain store; a pipeline and a valve are arranged on the store wall to fill nitrogen into the grain store; the store wall is provided with an entry inspection door; an air lock store is arranged on a cover board of the entry inspection door, is communicated with the grain store through an air lock valve and the outside through a sampling valve; a discharge valve, a discharge pipeline and a conveying pipeline with a turnover valve are arranged in the center of the bottom of the store; and an electroheat low-temperature drying system, a temperature sensor and a humidity sensor are arranged in the grain store, and the temperature sensor and the humidity sensor can detect temperature and humidity in the grain store respectively, so that oxygen and humidity during the period of grain storage can be controlled by the vacuum technology, and the grains are enforced to be in natural dormancy. Therefore, speed of natural exhaustion of the grains can be controlled to achieve the aim of prolonging the tenure of storage of the grains to prevent deterioration, and the grain store has low cost, easy construction and wide application range.

Description

technical field [0001] The invention relates to a method and equipment for prolonging the storage life of cereals and beans without deterioration. Background technique [0002] The country puts food first, and the people take food as the sky. Sufficient food reserves are the strategic goal of the country's long-term stability. At present, the grain storage methods in the world have not solved the problem of aging of grain storage over time, resulting in the inability to store a large amount of surplus grain in harvest years. In the face of successive years of natural disasters, there is a danger that there will be no high-quality grain supply. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a vacuum technology to control the value of oxygen and humidity during grain storage, to force the grain to dormant naturally, thereby controlling the speed of natural depletion of grain, and to prolon...
