Vacuum pump MPA2005 for smart rice bucket

 Is it troublesome to rice insects? However, the current rice buckets are mainly made of plastic and stainless steel, which cannot solve the problem of rice storage and prevent rice insects. In the true sense, the solution to the preservation of rice, the inhibition of the development of rice insects and the elimination of bacteria can only be solved by vacuum.

The smart rice bucket adopts intelligent constant pressure technology to automatically monitor the vacuum environment to realize the functions of vacuum preservation, insect-proof, mold-proof, and moisture-proof. When the vacuum reaches -60KPA, it will automatically stop vacuuming, and when it is lower than -20KPA, it will automatically start vacuuming. Because -60KPA is high-vacuum storage state, 5 times longer than the normal storage environment, the survival rate of bacterial is almost 0, moisture-proof and mildew-proof and keep fresh.

An important part of the smart rice bucket is the vacuum pump. Vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physical chemical methods to pump air from the pumped container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space.

Working principle:
Rotary DC diaphragm air pumps, also known as piston pumps and plunger pumps, are reciprocating pumps that actively use plungers or pistons to move the medium through a cylindrical chamber. They use a mechanism (usually rotation) to create a reciprocating motion along an axis, thereby increasing the pressure to allow gas or fluid to pass through the cylinder or working cylinder of the pump. The pressure in the chamber drives the two valve suction and discharge points. Specifically, the air flow rate is proportional to the motor speed, piston stroke and piston diameter.
