Description

A dairy product sterilization membrane filtration device Technical Field

[0001] This utility model relates to the technical field of dairy product processing, specifically to a dairy product sterilization membrane filtration device. Background Technology

[0002] Dairy products refer to various foods made using cow's milk or sheep's milk and their processed products as the main raw materials, with or without the addition of appropriate amounts of vitamins, minerals and other auxiliary materials, and processed under the conditions required by laws, regulations and standards. They are also called cream products.

[0003] In the process of dairy product processing, sterilization filtration is required. There is an existing purification device for dairy product processing, such as the one with patent publication number CN211153193U. It can first use a filter screen to filter the dairy product liquid, which can separate low-molecular-weight water, salt and lactose from the milk liquid, and can improve the ratio of protein, lactose and salt in the concentrate. Then, it uses a sterilization membrane to remove bacteria from the liquid by physical retention method to achieve sterilization. The device used is a filter with micropores.

[0004] However, the slow flow rate of raw materials from cattle in this device results in low efficiency and insufficient practicality. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a dairy product sterilization membrane filtration device with a screw-driven lifting piston mechanism that can apply extremely high pressure to the internal raw milk sterilization filtration, and the sterilization membrane is replaceable, thus improving its practicality.

The top left and right sides of the top of the top of the top frame are respectively connected to the top of a set of guide bars. The middle part of the left and right sides of the piston top is respectively connected to the bottom end of a set of sliding sleeves. The inner wall of each set of sliding sleeves is slidably connected to the outer wall of the guide bar on the same side. The inner side of the piston is connected to one side of the input hose. A set of one-way valves is installed on the output hose and the input hose respectively.

[0015] Compared with the prior art, this utility model provides a dairy product sterilization membrane filtration device, which has the following beneficial effects:

[0016] The other end of the inlet hose connects to the milk source. The sterilization membrane is installed inside the inner threaded cap and sealed closed by the inner threaded cap to the outside of the sterilization membrane. With the piston at the bottom of the transfer cylinder as the initial state, the reciprocating motor rotates the threaded rod. The threaded rod engages with the threaded tube and is slidably constrained by the guide bars, sliding sleeves, and one-way valves on both sides, creating negative pressure inside the transfer cylinder. Under the action of the corresponding one-way valve, the outlet hose is blocked, and raw milk can be fed into the inlet hose.

The other side of the input hose 7 is connected to the milk source. The sterilization membrane 3 is installed in the inner threaded cover 4 and sealed and closed on the outside of the sterilization membrane 3 by the inner threaded cover 4 screwed on. With the piston 6 in the lowest position inside the transfer cylinder 1 as the initial state, the reciprocating motor 9 runs, causing the threaded rod 10 to rotate. Rod 10 is screwed into threaded tube 11. Through the sliding constraint of guide bars 12, sliding sleeve 13 and one-way valve 21 on both sides, negative pressure is created inside the transfer cylinder 1. Under the action of the corresponding one-way valve 21, the output hose 5 is blocked, and the input hose 7 can input raw milk. After reaching the transfer cylinder 1, the reciprocating motor 9 reverses, causing the piston 6 to press down, and the internal raw milk is filtered through the sterilization membrane 3 and output through the output hose 5. When not in use, the inner threaded cover 4 can be rotated and screwed off outside the lower threaded opening 2, and the sterilization membrane 3 can be removed and replaced.

After reaching the transfer cylinder 1, the reciprocating motor 9 reverses, causing the piston 6 to press down. The raw milk inside is filtered through the sterilization membrane 3 and output through the output hose 5. When not in use, the inner threaded cap 4 can be removed by rotating the screw on the outside of the lower threaded opening 2, and the sterilization membrane 3 can be removed and replaced.
