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 move between a first position communicating with the discharging opening and a second position communicating with the material taking opening. And the sealing piececan move between a sealing position for sealing the material taking opening and an opening position for opening the material taking 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, the containing space for accommodating the food materials can be subjected to air exhaust through the pressure reducing unit, so that a negative pressure environment is formed in the containing space, the air content in the containing space is reduced, and the respiratory action of the food materials in the storage process can be slowed down. The food materials in the containing space are 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 tend to buy a large amount of food materials such as rice at one time, and use rice storage devices such as plastic rice buckets, metal rice buckets, and ceramic rice buckets to store them. Most of the above-mentioned rice storage devices simply isolate the space for storing rice from the outside space, and cannot control various parameters of the rice storage space such as temperature and humidity. For example, rice will respire during long-term storage and generate more heat. However, in a closed storage space, the heat is not easy to dissipate, and the higher temperature environment is likely to cause food spoilage. In addition, when the rice is taken from the rice storage device, the storage space is connected with the external environment, and its temperature and humidity are easily affected by the e...

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
