Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a sampling device for detecting the quality of fresh milk. Background Art

[0002] Fresh milk is transported from the pasture to the dairy products processing plant at a constant temperature by a milk tanker. Before unloading the fresh milk, the lead seal of the milk tanker can only be opened under the supervision of relevant staff, and a preliminary quick inspection is carried out. Only the fresh milk that passes the inspection can be transported into the milk tank of the dairy products processing plant. The fresh milk stored in the milk tank generally does not exceed 24 hours and is then transported to the production line.

[0003] The fresh milk input into the milk tank has been preliminarily detected. After being temporarily stored in the milk tank, it is directly transported to the production line for preliminary pasteurization. Even though the milk tank already has the functions of low-temperature refrigeration in a high-temperature environment and heating and heat preservation in a low-temperature environment, in order to further ensure the food safety of fresh milk, we have added a step of sampling inspection between the milk tank storage and pasteurization to ensure the hygienic safety of the fresh milk stored in the milk tank. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the utility model provides a sampling device for detecting the quality of fresh milk, which is used to add a step of sampling inspection between the milk tank storage and pasteurization to ensure the hygienic safety of the fresh milk stored in the milk tank.

[0006] A sampling device for detecting the quality of fresh milk includes a connecting pipe installed on a conveying pipeline. A sampling branch pipe is fixedly connected to the bottom of the connecting pipe. A stop valve is arranged on the sampling branch pipe. A sampling cylinder is movably installed at the bottom of the sampling branch pipe. A connecting frame is fixedly connected to the bottom of the sampling cylinder. A hand-operated screw rod is rotatably connected to the bottom of the connecting frame. The top pipe of the hand-operated screw rod is rotatably connected to a piston body, and the piston body is movably inserted into the sampling cylinder.

[0007] Preferably, the sampling cylinder includes a connecting port and a sealing cover adapted to the connecting port. Both the sealing cover and the sampling branch pipe are threadedly connected to the connecting port.

[0008] Preferably, the piston body includes a connecting seat rotatably connected to the top end of the hand-operated screw rod, a cylinder piston fixedly connected to the connecting seat and slidably connected to the inner side wall of the sampling cylinder, and an interface piston arranged on the cylinder piston and slidably connected to the inner wall of the connecting port.

[0009] Preferably, the cylinder piston and the interface piston are of an integral structure.

[0010] Preferably, a fillet structure is provided at the intersection of the upper surface and the side surface of the cylinder piston and the interface piston, and the thickness dimension of the interface piston is the same as the depth dimension of the connection port.

[0011] Preferably, the sealing cover includes a cover body threadedly connected to the connection port and an inverted placement seat provided at the top of the cover body and integrally formed therewith.

[0012] Preferably, the inverted placement seat is disc-shaped, the connecting frame is a rectangular parallelepiped frame, and the diameter of the inverted placement seat is greater than the diameter of the sampling cylinder and the width of the connecting frame.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] When the present utility model closes the stop valve, the presence of the connecting pipe does not affect the normal transportation of fresh milk in the transportation pipeline. Rotate the hand-operated screw rod to drive the piston body to move upward, so that when the cylinder piston reaches the top of the inner wall of the sampling cylinder, the interface piston also moves into the connection port and is flush with the top of the connection port, exhausting the air inside the sampling cylinder. Install the sampling cylinder, open the stop valve, and rotate the hand-operated screw rod to make the piston body move downward, then fresh milk can be randomly sampled from the transportation pipeline. Then close the stop valve, remove the sampling cylinder, and it can be sealed through the sealing cover, thus adding a sampling operation between the storage of fresh milk in the milk tank and pasteurization, adding a sampling inspection process, and achieving the purpose of further ensuring the hygienic safety of the fresh milk stored in the milk tank.
