Description

Technical Field

[0001] The invention relates to a milk processing sampling and fresh-keeping device, belonging to the technical field of milk. Background Art

[0002] Milk, an ancient natural drink, is known as "white blood". Its importance to the human body is self-evident. However, due to differences in personal taste and the body's ability to digest milk, some people may not be suitable for drinking pure milk directly. In order to meet the needs of these people, different liquid ingredients are usually added to pure milk, and a variety of dairy products are made through mixed processing. In this process, in order to ensure product quality, milk must be sampled and tested at multiple points. However, the time consumed during sample transportation often leads to a decrease in sample quality. Therefore, freshness treatment is particularly critical; The commonly used sampling method at present is to collect milk samples into bottles by pouring or scooping, then seal them with a lid, and place them in a container filled with ice or coolant to maintain a low temperature environment, thereby completing sampling and preservation. However, this method has a significant flaw: the milk sample is in a static state in the bottle. After long-term storage, some milk samples close to the container wall are prone to frost or coagulation, which not only increases the risk of blockage during subsequent processing, but also forces experimenters to take additional heating or shaking steps to restore sample fluidity, thereby extending the overall operation time and increasing the possibility of sample deterioration, which will affect the sampling effect and quality.

After the sampling is completed, the sub-joint 56 and the female joint 57 are reassembled, and the two clamping plates 62 are used to squeeze the air bag 6 again, so that negative pressure is generated in the transparent tank 5, and under the action of the negative pressure, the milk sample on the lower side of the transparent tank 5 flows back to the upper side of the transparent tank 5 along the hose 51, the straw 52, ​​the connecting tube 55 and the metal tube 54, so that the milk sample is stored in a flowing manner along the hose 51, the straw 52, ​​the connecting tube 55, the metal tube 54 and the transparent tank 5; Then, the transparent tank 5 storing the milk sample is placed in the inner cylinder 4, and the corresponding rectangular block 25 is inserted into the corresponding rectangular cylinder 24 and contacts the corresponding movable plate 26, so that the transparent tank 5 is positioned and placed in the inner cylinder 4, and then the sealing cover 1 and the outer shell 2 are restricted to be installed through two lock buckles 11 and two movable lock seats 21. At this time, the sealing cover 1 will press the lifting device 53, so that the transparent tank 5 moves down and contacts the rectangular cylinder 24, so that the movable plate 26 moves down, thereby compressing the elastic member 27, so that the elastic member 27 generates elastic force, and at the same time, the transparent tank 5 is restricted to be installed in the inner cylinder 4, and then the liquid pump 32, the spiral tube 22 and the liquid discharge pipe 23 are used to make the cold liquid flow in the spiral tube 22, and the cold liquid flowing in the spiral tube 22 will cool the space in the inner cylinder 4 through a plurality of through grooves 41, and at the same time, the refrigerator 33 refrigerates the cold liquid in the storage cavity, so that the milk sample in the transparent tank 5 is refrigerated and preserved; After the multi-position sampling is completed, the shell 2 and other components are moved to the laboratory, and then the two lock buckles 11 and the two movable lock seats 21 are disassembled in an assembled state, thereby releasing the restriction on the sealing cover 1, and then the sealing cover 1 is taken out. At this time, under the elastic force of the elastic member 27, the movable plate 26 moves upward along the rectangular tube 24, so that the rectangular block 25 and the rectangular tube 24 move relative to each other, and the transparent tank 5 moves upward, so that the lifting device 53 moves to the top of the shell 2, and then the lifting device 53 is used to take out the transparent tank 5, and then the hose 51 is used to transport the milk sample in the transparent tank 5 to the milk detection device, so as to complete the milk detection, and realize the convenient pick-up and placement operation of the transparent tank 5, effectively reducing the probability of interference in the removal operation of the transparent tank 5 due to condensation between the rectangular block 25 and the rectangular tube 24 at low temperature, effectively ensuring normal detection operations, and effectively ensuring the sampling effect and quality.
