Airtight transporting blending metering system and method for powder culture medium

Abstract

The invention provides a custody transfer blending and dosing measuring system for the powder culture medium, which includes a grinding and screening device, a dosing and sub-packing device, a vacuum appending machine and a pure air-compressing device of the dosing and sub-packing device. The feed opening of the grinding and screening device is hermetically connected with the inlet orifice of the vacuum appending machine of the dosing and sub-packing device by a transfer pipe, the discharge hole of the vacuum appending machine of the dosing and sub-packing device is hermetically connected with the inlet orifice of the dosing and sub-packing device by a transfer pipe, the pure air-compressing device supplies pure compressed air for the vacuum appending machine of the dosing and sub-packing device; the powder culture medium is transferred hermetically from the grinding and screening device to the dosing and sub-packing device for dosing and sub-packing operation by the vacuum appending machine of the dosing and sub-packing device. The system can realize the hermetic automatic transfer, blending and dosing of the powder culture medium, which reduces the pollution on the powder culture medium and the environment, eliminates the dust pollution and reduces the labor intensity. The invention also provides a custody transfer measuring method for the powder culture medium.

Description

technical field [0001] The invention relates to a system and method for airtight conveying, mixing and metering of powder culture medium. Background technique [0002] At present, culture medium production enterprises collect the finished or semi-finished powder medium products manually, transport them to the mixing equipment for mixing, and then take them out manually, weigh them and pack them; or use a grinding device to mix them evenly, and then Manual metering and dispensing, the entire transportation, metering and dispensing process is not well connected and optimized, and there is no good connection and delivery method, which may cause secondary pollution of the powder medium during the transfer process, and the production efficiency is low. The batch production capacity is small, the labor intensity is high, and the dust generated is large. What's more serious, because most of the operation links are open, it is easy to make the microbial content and bacterial endotox...

[0002] At present, culture medium production enterprises collect the finished or semi-finished powder medium products manually, transport them to the mixing equipment for mixing, and then take them out manually, weigh them and pack them; or use a grinding device to mix them evenly, and then Manual metering and dispensing, the entire transportation, metering and dispensing process is not well connected and optimized, and there is no good connection and delivery method, which may cause secondary pollution of the powder medium during the transfer process, and the production efficiency is low. The batch production capacity is small, the labor intensity is high, and the dust generated is large. What's more serious, because most of the operation links are open, it is easy to make the microbial content and bacterial endotoxin in the finished and semi-finished powder culture medium exceed the standard, which is difficult for downstream pharmaceutical companies. Hidden dangers brought by the industry

In addition, the cleaning and sterilization of the existing mixing equipment mainly uses electric heating, and the sterilization is performed by increasing the temperature, which consumes a lot of energy and requires a dedicated cleaning room to complete
