Description

Technical Field

[0001] The utility model relates to the technical field of raw material weighing, in particular to a dry powder culture medium raw material weighing device. Background Art

[0002] Dry powder culture medium raw materials refer to various dry chemical substances or compounds required for the preparation of microbial culture medium. These raw materials usually include carbon sources (such as glucose), nitrogen sources (such as amino acids), inorganic salts (such as magnesium sulfate, phosphates), vitamins, amino acids, etc. These raw materials are essential nutrients for the cultivation of microorganisms, providing the energy and basic building blocks required for microbial growth and metabolism. By accurately proportioning these dry powder raw materials, specific types of culture media can be prepared to support the growth and reproduction of different microorganisms and promote their application in laboratory research, industrial production, etc. Therefore, the selection and use of dry powder culture medium raw materials have an important impact on microbiological experiments and applications.

[0003] For example, a raw material weighing device with publication number CN220288747U includes a main device for storing different raw materials and unloading materials, and also includes a moving device arranged on the main device for horizontal movement to weigh different raw materials. A cleaning device for blowing and sweeping residues is arranged above the moving device. The device improves the weighing accuracy by the setting of separate and continuous weighing of different types of raw materials, improves the accuracy of subsequent weighing by the setting of blowing and sweeping residues with a flat brush, and improves the weighing speed by the setting of horizontal movement to weigh all raw materials.

[0004] Although this patent can effectively solve the problem of weighing different types of raw materials separately, it has limitations when dealing with culture medium powder raw materials that need to be filled and packaged. Specifically, this patent cannot achieve equal filling of multiple batches of culture medium powder raw materials, which means that it is impossible to accurately know the exact capacity of culture medium powder raw materials in each packaging bag. In addition, the existing raw material weighing equipment cannot perform weight detection on the filled packaging bags, resulting in the inability to accurately know the total weight of the culture medium powder raw materials in each packaging bag. Therefore, these limitations may cause some problems during actual use.

[0005] Therefore, we proposed a dry powder culture medium raw material weighing device to solve the above problems. Utility Model Content

During the quantitative filling process, the packaging bag can be firmly fixed on the sleeve frame to prevent the packaging bag from moving or falling off during the filling process, thereby ensuring the smooth progress of the packaging process and the filling accuracy.

This structural design is to prevent the outflow of raw materials in the non-discharging state. The material blocking cover can be removed when discharging is required, so that the discharge of the raw materials can be controlled, and at the same time it can be quickly closed after the discharging is completed.
