Household grain storage cabinet

Abstract

The invention relates to a household grain storage cabinet, and provides a solution for achieving the purposes of preventing moths, mildew and moisture and prolonging the quality guarantee period of grains by changing the internal pressure of the grain storage cabinet so as to overcome the defects and deficiencies in the prior art. The household grain storage cabinet comprises a sealed grain storage cabinet, a pressure system and a control system. The sealed grain storage cabinet comprises a barrel body, an upper cover and a sealing ring; the pressure system comprises a pressure pump, a one-way valve and a pipeline; the control system comprises a control panel, a sensor, a circuit board and the like. When the grain storage cabinet works, air is pumped out of the grain storage cabinet or pumped into the grain storage cabinet through the pressure system and the control system, and the pressure, humidity and oxygen concentration in the grain storage cabinet can be changed, so that the survival conditions of moths, mildew and the like are changed, and the purposes of moisture prevention, insect prevention and mildew prevention are achieved.

Description

technical field [0001] The invention relates to the technical field of grain storage cabinets, in particular to a grain storage cabinet which prolongs the shelf life of grain by changing the pressure. Background technique [0002] At present, the commonly used grain storage utensils in the family mainly use cartons, plastic bags, plastic boxes, glass bottles, plastic bottles, etc. as grain storage utensils. However, the function is single, and generally only has the function of storage, and does not have the function of maintaining grain quality. Short-term storage is okay, but if it is stored for a long time, the grain is easily affected by the surrounding temperature and humidity. The mold and moths in it can easily reproduce and hatch under the action of appropriate pressure, oxygen, temperature, and humidity, which will accelerate the aging of the grain. Moisture, mildew and moths will lead to the loss of food nutrients, affect human health and increase food loss. For ...

However, the function is single, and generally only has the function of storage, and does not have the function of maintaining grain quality.

Short-term storage is okay, but if it is stored for a long time, the grain is easily affected by the surrounding temperature and humidity. The mold and moths in it can easily reproduce and hatch under the action of appropriate pressure, oxygen, temperature, and humidity, which will accelerate the aging of the grain. Moisture, mildew and moths will lead to the loss of food nutrients, affect human health and increase food loss

For the grain storage cabinets currently on the market, either the structure is simple and the function is single, and they only have the functions of sealing and storage, such as the household grain storage container with the patent number 200520200062.3 and the household grain storage tank with the patent number 200320104178.8, insect-proof and quality-preserving The effect is not ideal; either refrigeration technology is used to reduce the temperature to achieve the purpose of storing grain, such as the low-temperature rice cabinet with patent number 201810579222.1 and the refrigeration structure of a rice storage cabinet with patent number 201620114383.X, This type of technology has complex structure, high cost, serious energy consumption and high cost of use
