Rice storage device

Abstract

The invention discloses a rice storage device. The rice storage device comprises a containing unit with a containing space, a material taking unit and a pressure reducing unit. A discharging opening is formed in the bottom of the containing space. The material taking unit comprises a material taking opening, a material taking cavity and a sealing piece. The material taking cavity is located abovethe material taking opening and can rotate and move between a first position communicating with the discharging opening and a second position communicating with the material taking opening around therotating center axis. The sealing piece and the material taking cavity integrally rotate around the rotating center axis so as to seal or open the discharging opening. The pressure reducing unit communicates with the containing space and is used for enabling the pressure in the containing space to be lower than preset pressure. According to the invention, a negative pressure environment can be formed in the containing space through the pressure reducing unit, the air content is reduced, and the respiratory action of food materials can be slowed down. The food materials in the containing spaceare taken out through the material taking unit, the frequency and degree of communication between the containing space and the external environment can be reduced, and long-time fresh keeping of the food materials is facilitated.

Description

Technical field [0001] The invention relates to the field of kitchen utensils, in particular to a rice storage device. Background technique [0002] In daily life, people are accustomed to buying large quantities of foodstuffs such as rice and storing them in rice storage devices such as plastic rice buckets, metal rice buckets, and ceramic rice buckets. Most of the above-mentioned rice storage devices simply isolate their own space for storing rice from the outside space, and cannot control various parameters such as temperature and humidity of the rice storage space. For example, when rice is stored for a long time, respiration will occur and generate more heat. However, heat is not easy to dissipate in a closed storage space, and a higher temperature environment is likely to cause the food to spoil. In addition, when rice is taken from the rice storage device, the storage space is connected to the external environment, and its temperature and humidity are easily affected by ...

AI Technical Summary

Problems solved by technology

However, in a closed storage space, the heat is not easy to dissipate, and the high temperature environment is easy to cause food spoilage

In addition, when taking rice from the rice storage device, the storage space is connected with the external environment, and its temperature and humidity are easily affected by the external environment

Long-term storage is prone to problems such as moisture, mildew, aging, and insects, so it is difficult to keep fresh for a long time and bring a bad experience to users
