Description

Technical Field

[0001] This utility model relates to the field of dairy product production and transportation technology, specifically a raw milk filtration and loading device. Background Technology

[0002] Raw milk generally refers to unprocessed milk that has not undergone sterilization or homogenization. It is an essential raw material in dairy production. Dairy companies inspect raw milk according to the National Food Safety Standard for Raw Milk when purchasing it; raw milk that fails to meet the standards is not allowed to enter the production process. High-quality natural raw milk comes from the udders of healthy animals, and the entire production process must adhere to the hygiene standards for raw milk. The final test results show low total bacterial count, low somatic cell count, normal milk composition, no antibiotic residues, no sediment or off-odors, and no added water – truly natural milk. Because raw milk has not undergone homogenization or other processing, strict control of milk temperature, impurities, and microorganisms is necessary during loading and transportation.

[0003] In current technology, when loading raw milk onto trucks, the raw milk delivery pipe is usually directly inserted into the inlet of the transport vehicle's storage tank. Since the inner diameter of the storage tank's inlet is generally larger than the outer diameter of the raw milk delivery pipe, it is necessary to manually hold the raw milk delivery pipe to fix it or temporarily use other tools to fix it during loading. This operation is inconvenient, non-standard, and can easily cause raw milk to spill.

[0004] In addition, during the loading process, impurities or foreign objects such as sand, dust, or insects and flies can easily enter the storage tank, especially in rainy, snowy, or windy weather, where the probability of impurities or foreign objects entering the storage tank increases significantly. To prevent impurities or foreign objects from entering the storage tank during loading, the existing technology generally involves covering the inlet of the storage tank with a layer of gauze. The raw milk is filtered through the gauze before entering the storage tank. The gauze can filter larger impurities or foreign objects, but its filtering effect on small particles or impurities such as rainwater and dust is limited. Furthermore, the use of gauze is not standardized, and the connection between the gauze and the inlet of the storage tank is inconvenient. The inlet of the storage tank generally does not have a structure for connecting the gauze, which poses a risk that the gauze may fall into the storage tank or that unclean gauze may directly contaminate the raw milk.
