Description

Technical Field

[0002] Food processing measurement refers to the processing of grain milling, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, as well as vegetables, fruits, nuts and other foods directly using agricultural, forestry, animal husbandry and fishery products as raw materials. It is a type of agricultural product processing industry in a broad sense. Food processing steps are complicated, and measurement is one of them. Specifically, the processed food is weighed after being put into the packaging bag, so metering devices are needed;

[0003] For example, Patent No. CN201910311889.8 discloses a high-speed metering and filling device, in which a metering box is arranged below a silo to receive the material flowing out of the lower discharge port of the silo, a scraper is arranged above the metering box to scrape the material on the top of the metering box, and a knife plate is arranged below the metering box to block the bottom opening of the metering box when receiving the material and to lower the material when the silo is full.

[0004] A metering device and method in the above-mentioned patent has the following shortcomings: grain particles (such as corn and wheat) have large differences in fluidity and are prone to arching and clogging.
