Description

Technical Field

[0001] This utility model relates to the field of oiled skin processing technology, specifically to an oiled skin salt water permeation mechanism. Background Technology

[0002] Tofu skin, also known as fried tofu skin, is made by lifting up the natural oil film that forms on the surface of boiled soy milk and letting it dry. It's a traditional Chinese soy product. Tofu skin is rich in nutrients, high in protein and amino acids. Modern scientific analysis shows it also contains 18 essential trace elements, including iron, calcium, and molybdenum. It can boost immunity and promote physical and intellectual development in children, and long-term consumption by the elderly can prolong life. It's especially beneficial for postpartum women, helping them recover quickly and increasing breast milk production. Tofu skin is also easily digestible and quickly absorbed, making it a suitable food for women, children, the elderly, and those with weakened immune systems.

[0003] During the processing of bean curd sheets, they need to be brine-treated to leave a small amount of salt on the surface, which changes their taste and also helps with storage and processing. Currently, the industry basically controls the brine level manually when brine-treating bean curd sheets. The level fluctuates, which can easily lead to uneven salt content in the bean curd sheets after brine treatment, affecting product quality. Moreover, the excess brine adhering to the surface of the bean curd sheets will also increase the energy consumption for drying. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a brine-water treatment mechanism for oily skin, which can automatically adjust the liquid level in the brine tank and scrape off excess brine from the surface of the oily skin using a salt scraper shaft, thus saving brine loss and reducing drying energy consumption.

[0005] This utility model is achieved through the following technical solution:

[0006] A brine conveying mechanism for oily skin is provided, comprising a feed belt and a discharge belt. A brine tank is disposed between the feed belt and the discharge belt below in the conveying direction. An oily skin transition shaft parallel to the width direction of the oily skin is rotatably installed inside the brine tank. A fixed salt scraping shaft parallel to the oily skin transition shaft and capable of abutting against the upper surface of the oily skin is also installed between the oily skin transition shaft and the discharge belt inside the brine tank. A connecting port is opened on the outer side wall of the brine tank on one side of the oily skin length direction, and an inlet pipe is connected to it through a liquid level adjustment mechanism.

[0007] Furthermore, the liquid level regulating mechanism includes a water receiving box fixed to the outer wall of the brine tank and connected to the brine tank. An L-shaped notch is formed at the upper corner of the water receiving box near the side wall of the brine tank. A float is provided inside the water receiving box at the L-shaped notch. A water outlet cavity connected to the inlet pipe is connected to the inner top surface of the water receiving box. A water baffle extending to the bottom of the water outlet cavity and having an area not less than the cross-section of the water outlet cavity is connected to the side of the float.

[0008] The water receiving box is connected to the brine tank. The float in the water receiving tank can rise and fall automatically according to the buoyancy of the liquid level in the brine tank. When the float rises and falls, it drives the water baffle on its side to rise and fall synchronously. The amount of brine entering the water receiving box can be controlled by blocking the end face of the water outlet by the water baffle, thereby realizing liquid level regulation and control.

[0009] Preferably, the side of the float is vertically slidably connected to the inner wall of the water receiving box via a slider and a groove.

[0010] The side of the float is slidably connected to the inner wall of the water receiving box through a groove and a slider, which can guide and limit the up and down movement of the float, ensuring the stability of the float's up and down movement, thereby achieving stable sealing of the water outlet end face of the float's side baffle, ensuring the stability of liquid level regulation.

[0011] Preferably, a rotating salt scraping shaft is installed inside the brine tank between the fixed salt scraping shaft and the discharge belt. This rotating shaft is parallel to the fixed salt scraping shaft and abuts against the lower surface of the oil skin.

[0012] By setting a rotating salt scraper between the fixed salt scraper and the discharge belt, the rotating salt scraper comes into contact with the lower surface of the oil skin. On the one hand, it can block and scrape off the salt particles attached to the lower surface of the oil skin, causing them to separate from the lower surface of the oil skin. On the other hand, the rotation can reduce the frictional resistance of the oil skin conveying, ensuring the stability of the oil skin conveying.

[0013] Furthermore, the bottom of the brine tank is a V-shaped bottom that convexes downwards.

[0014] The bottom of the brine tank is designed in a V-shape, which helps the precipitated salts to sink to the bottom of the V-shaped tank, preventing them from contacting the oil skin and adhering to it, thus avoiding uneven salinity distribution on the oil skin.

[0015] Furthermore, a drain outlet is opened on the side wall of the brine tank on the other side along the length of the oil slick, and the drain outlet is located at the lowest end of the V-shaped bottom surface.

[0016] A drain outlet is provided on the side wall of the brine tank, and the drain outlet is located at the lowest end of the V-shaped bottom surface. The brine in the brine tank can be drained through the drain outlet, which facilitates the replacement of the brine in the brine tank and ensures product quality.

[0017] Furthermore, both the feed belt and the discharge belt are belts with diamond mesh.

[0018] By setting the surfaces of the feed belt and discharge belt to have diamond mesh, the friction between the oil film and the belt can be increased, allowing the oil film to smoothly enter the discharge belt from the feed belt through the brine tank, thus ensuring the stability of the oil film conveying.

[0019] The beneficial effects of this utility model are:

[0020] This invention achieves automatic adjustment of the liquid level in the brine tank by installing a water receiving box on the side wall of the brine tank and slidingly connecting a float inside the water receiving box. The buoyancy controls the raising and lowering of the float, which, together with the water-blocking part on its side, seals and separates the end face of the water outlet, thus realizing automatic replenishment of brine.

[0021] The oil skin is guided by the oil skin transition shaft into the brine tank to soak in brine. Before entering the discharge belt, it comes into contact with the oil skin by a fixed salt scraper shaft. As the oil skin moves, the friction between it and the fixed salt scraper shaft can scrape off the excess brine adhering to the surface of the oil skin, thereby saving brine consumption and reducing subsequent drying energy consumption, effectively reducing production costs.

[0028] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0029] Example 1:

[0030] like Figure 1 and Figure 2 As shown, an oil-skin conveying mechanism includes a feed belt 1 and a discharge belt 2. In order to increase the friction between the oil skin 4 and the belt and ensure the continuity of oil skin conveying, both the feed belt 1 and the discharge belt 2 are belts with diamond mesh.

[0031] A brine tank 3 is provided between the feed belt 1 and the discharge belt 2 below the conveying direction. In this embodiment, the bottom surface of the brine tank 3 is a V-shaped bottom surface that convexes downward.

[0032] A transition shaft 5, parallel to the width direction of the oil film 4, is rotatably installed inside the brine tank 3. A fixed salt scraping shaft 6, parallel to the transition shaft 5 and capable of abutting against the upper surface of the oil film 4, is also installed between the transition shaft 5 and the discharge belt 2 inside the brine tank 3. An inlet 12 is provided on the outer wall of the brine tank 3 along one side of the length direction of the oil film 4, and an inlet pipe 10 is connected to it via a liquid level adjustment mechanism. A drain 11 is provided on the side wall of the brine tank 3 along the other side of the length direction of the oil film 4, and the drain 11 is located at the lowest end of the V-shaped bottom surface.

[0033] The liquid level adjustment mechanism includes a water receiving box 7 fixed to the outer wall of the brine tank 3 and connected to the brine tank 3 through a connecting port 12. An L-shaped notch 13 is formed at the upper corner of the water receiving box 7 near the side wall of the brine tank 3. A float 9 is provided inside the water receiving box 7 at the L-shaped notch 13. A water outlet cavity 14 connected to the liquid inlet pipe 10 is connected to the inner top surface of the water receiving box 7. A water-blocking part 11 extending to the bottom of the water outlet cavity 14 and having an area not less than the cross-section of the water outlet cavity 14 is connected to the side of the float 9.

[0034] In use, before the production of the oil sheet, the inlet pipe 10 for conveying brine is opened, and the brine enters the receiving box 7 through the inlet 8. The receiving box 7 is connected to the brine tank 3 through the connecting port 12, allowing the brine to enter the brine tank 3. When the liquid level rises, the float 9 experiences increased buoyancy, and the brine lifts the float 9. Simultaneously, the water-blocking part 11 on the side of the float 9 rises, blocking the outlet at the end face of the outlet chamber 14. As the oil sheet 4 carries away the brine, the brine level in the brine tank 3 decreases, the float 9 descends, and it opens the outlet at the end face of the outlet chamber 14, allowing the brine to re-enter the brine tank 3, thus achieving automatic replenishment of the brine.

[0035] The oil skin produced by the oil skin machine is conveyed to the brine tank 3 via the feed belt 1. The oil skin 4 enters the discharge belt 2 from the lower part of the oil skin transition shaft 5. The discharge belt 2 drives the oil skin 4 to move towards the discharge port. An oil skin traction device, such as a rotating clamping roller, can be set behind the discharge port to pull the oil skin to move from the feed direction to the discharge direction. The liquid level in the brine tank 3 must exceed the oil skin transition shaft 5 to ensure that the oil skin 4 passes through the brine. The fixed salt scraping shaft 6 is placed in the slot of the brine tank 3. The fixed salt scraping shaft 6 does not rotate and will abut against the oil skin 4. In this way, the excess brine that has not penetrated the upper surface of the oil skin 4 will be scraped off by the fixed salt scraping shaft 6, which saves brine loss and reduces drying energy consumption.

[0036] Example 2:

[0037] like Figure 4 As shown, this embodiment, based on embodiment 1, limits and guides the lifting and lowering action of the float 9. In order to ensure the stability of the float 9 floating up and down, the side of the float 9 and the inner wall of the water receiving box 7 are vertically slidably connected by a slider 15 and a chute.

[0038] like Figure 3 As shown, a rotating salt scraping shaft 16, which is parallel to the fixed salt scraping shaft 6 and abuts against the lower surface of the oil skin 4, is also installed between the fixed salt scraping shaft 6 and the discharge belt 2 in the brine tank 3.

[0039] In this embodiment, compared to the technical solution of Embodiment 1, the salt scraping treatment of the upper and lower surfaces of the oil skin 4 can be achieved simultaneously. Excess brine that has not penetrated the upper and lower surfaces can be scraped off from the oil skin, effectively saving brine loss and reducing production costs.
