Problems solved by technology

[0004] 1. Complex structure and high cost;
[0005] 2. Due to the inflexible control of the switch of the discharge port, the weight of rice in the packaging bag varies widely, so that an excessive amount of rice has to be taken out of the packaging bag, resulting in low packaging efficiency and heavy workload. The staff has caused a lot of inconvenience

Abstract

The invention relates to the technical field of rice processing equipment, and discloses a rice vacuum packaging machine with precise metering, which includes a hopper fixed on a frame, the bottom of the hopper is connected to a discharge pipe for installing a packaging bag, and a first piston chamber is fixed on the base. The packaging bag is placed on the first piston installed in the first piston chamber. The first piston chamber is connected to the first cylinder through the first air pipe. The first cylinder is connected to a sliding block for blocking the discharge pipe. The first piston chamber The second cylinder is connected to the second cylinder through the second air pipe, and the second cylinder is connected to the second piston in the second piston chamber. A vacuum pump and a carbon dioxide booster pump are installed at both ends of the second piston chamber. The air pipe is connected with the first piston cavity. The invention can not only complete the accurate weighing of rice packaging, but also pack the rice for fresh storage.

Description

technical field [0001] The invention belongs to the technical field of rice processing equipment, in particular to a rice vacuum packaging machine with accurate measurement. Background technique [0002] Rice is the finished product of paddy rice after rice milling, peeling, cleaning, drying and other processes. It is the basic substance of people's life and the most basic nutrient. It is rich in carbohydrates, and also contains protein, fat, Vitamins and other minerals can provide comprehensive nutrition to the human body. [0003] The existing vacuum packaging machine can automatically extract the air in the packaging bag and complete the sealing process after reaching the predetermined vacuum degree, but it also has the following disadvantages: [0004] 1. Complex structure and high cost; [0005] 2. Due to the inflexible control of the switch of the discharge port, the weight of rice in the packaging bag varies widely, so that an excessive amount of rice has to be take...
