[0002] In the process of making birch sap cold brew, you first need to select fresh birch sap, and then place it in a low temperature environment for cold brewing, so as to maintain the natural taste and nutrients of the birch sap. Cold brewing can make the birch sap more refreshing and taste better, suitable as a summer drink to relieve heat. Birch sap cold brewing is a healthy and natural beverage making method suitable for people who like a cool taste.

[0003] The existing reverse osmosis equipment includes at least two reverse osmosis mechanisms, which are connected by a series of pumps and pipelines. Each stage of the reverse osmosis mechanism helps to further concentrate the birch sap and separate the clear liquid from the concentrated liquid. However, pretreatment is required before the birch sap is treated by reverse osmosis. The birch sap is initially filtered through pretreatment to remove large particles that may cause reverse osmosis membrane contamination. Generally, larger particle impurities in the birch sap are filtered through a filter. After a period of use, the filtered impurities will remain everywhere on the filter. These impurities will block part of the pore size, thereby affecting the filtration efficiency of the juice. Therefore, a reverse osmosis equipment for cold extraction of birch sap is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The pretreatment mechanism includes a treatment box 2, which is installed on the top of the base 1. A liquid inlet pipe 3 is fixedly passed through the top of the treatment box 2. A diversion pipe 7 is fixedly connected to the bottom of the liquid inlet pipe 3. A plurality of liquid outlet heads are installed at the bottom of the diversion pipe 7. A filter screen 10 is arranged inside the treatment box 2. A cleaning mechanism is installed inside the treatment box 2.

[0024] The cleaning mechanism includes a driving motor 4, which is fixedly mounted on the side wall of the processing box 2. A threaded rod 5 is fixedly connected to the output shaft of the driving motor 4. The threaded rod 5 penetrates the processing box 2 and is rotatably connected to the inside of the processing box 2. The external thread of the threaded rod 5 is connected to a connecting plate 17. A cleaning brush 9 is fixedly connected to the bottom of the connecting plate 17. A guide slide rod 6 is fixedly connected to the inside of the processing box 2. The connecting plate 17 is slidably connected to the outside of the guide slide rod 6.

[0025] It should be noted that the bottom of the cleaning brush 9 is in contact with the top of the filter screen 10. By driving the threaded rod 5 to rotate by the driving motor 4, the connecting plate 17 can drive the cleaning brush 9 to move horizontally to the left, thereby pushing all impurities on the filter screen 10 to the slag outlet 19, thereby preventing these impurities from blocking the aperture of the filter screen 10, ensuring the flow rate of the juice, and improving the filtration efficiency.

[0026] See also Figure 1 , Figure 2 A sealing assembly is installed on the processing box 2, and the sealing assembly includes a sealing plate 18. A slider 20 is fixedly connected to the top of the sealing plate 18. The slider 20 is slidably connected in a accommodating chamber 21 opened inside the processing box 2. A connecting rod 22 is fixedly connected to one side of the slider 20. The connecting rod 22 penetrates the processing box 2 and extends to the outside. A slag outlet 19 located at the bottom of the accommodating chamber 21 is opened on the side wall of the processing box 2. The sealing plate 18 penetrates the accommodating chamber 21 and is clamped in the slag outlet 19. An electric push rod 8 is installed on the side wall of the processing box 2.

[0027] The slag outlet 19 is blocked by a sealing plate 18 to prevent juice from flowing out of the slag outlet 19. A sealing gasket is installed between the sealing plate 18 and the inner wall of the slag outlet 19. The electric push rod 8 drives the sealing plate 18 to move upward into the accommodating chamber 21, so that the slag outlet 19 can be exposed, thereby facilitating the impurities on the filter screen 10 to be pushed out from the slag outlet 19 and fall into the impurity inlet box 11 for collection.

[0028] See also Figure 1 , Figure 4 The reverse osmosis mechanism includes a booster pump 12, a pure water outlet pipe 15, a waste water outlet pipe 16 and a plurality of reverse osmosis membrane groups 14. The reverse osmosis membrane group 14 is installed on the top of the base 1, the booster pump 12 is installed on the top of the base 1, the booster pump 12 is connected to the treatment box 2 through a pipeline, and a liquid guide pipe 13 is fixedly connected to the side of the booster pump 12 away from the treatment box 2.

[0029] It should be noted that the reverse osmosis module reverse osmosis membrane group 14 separates the solute and solvent in the solution under high pressure through a semipermeable membrane, allowing water to flow from one side of the membrane to the other side, while retaining dissolved salts, particles, bacteria and other impurities. The osmosis phenomenon refers to when a semipermeable membrane separates two solutions of different concentrations, the solvent in the lower concentration solution will naturally diffuse through the semipermeable membrane into the high concentration solution until the concentrations on both sides are balanced. The reverse osmosis process is based on osmosis, and is a process in which a higher pressure than the natural osmotic pressure is applied on the high concentration side to force the solvent to flow from the high concentration solution to the low concentration solution.

[0030] The working principle of the above embodiment is as follows: when in use, birch sap enters the diversion pipe 7 from the liquid inlet pipe 3 and is diverted and finally sprayed out from multiple liquid outlet heads. The flowing sap passes through the filter screen 10 to filter out larger impurity particles. When the filter screen 10 is used for a long time, the threaded rod 5 is driven to rotate by the driving motor 4. Under the limiting effect of the sliding connection between the guide slide bar 6 and the connecting plate 17, the connecting plate 17 can drive the cleaning brush 9 to move to the left, thereby pushing all impurities on the filter screen 10 to the slag outlet 19, thereby preventing these impurities from blocking the aperture of the filter screen 10, ensuring the flow rate of the sap, and improving the filtration efficiency. The birch sap raw water filtered in the treatment box 2 is extracted by the booster pump 12, and the raw water is reverse osmosis filtered through multiple reverse osmosis membrane groups 14. The filtered pure water will be discharged from the pure water outlet pipe 15, and the waste water will be discharged from the waste water outlet pipe 16.
