Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a soybean milk residue-liquid separator. Background Technology

[0002] The production process of soy products such as soy milk, tofu, dried tofu, and fermented bean curd includes: grinding, separating the pulp from the residue, boiling the pulp, coagulation, pressing, and further processing. Pulp-residue separation is further divided into raw pulp separation and cooked pulp separation. Soy products such as soy milk, tofu, and dried tofu made using cooked pulp separation have a much better texture, chewiness, and quality than those made using raw pulp, and the yield is also much higher. The soy milk separation method in the original soy milk liquid involves grinding soybeans in a grinder, directly separating them into soy milk and soy residue using the grinder's internal separation device, or using a dedicated centrifuge to separate them. The soy milk is then heated in a boiling device to become cooked soy milk. The cooked pulp separation method involves not separating the ground soy milk and soy residue (also called slurry) initially, but cooking them together in a boiling device before separating them. Cooked soy milk is used to produce various soy products. However, the centrifuges currently used to separate raw soy milk cannot separate cooked soy milk. Cooked soy milk contains a lot of sticky substances that will clog the centrifuge's filter screen during separation. Therefore, it is impossible to separate it using centrifugal machinery. The only way is to use an old method: using gauze, suspending the edges of the gauze with ropes, pouring the cooked soy milk onto the gauze, and manually shaking the gauze, commonly known as "shaking the bag". This primitive and backward method is labor-intensive, requires many people, has poor separation effect, low output, and high production cost. It cannot meet the requirements of mechanized, automated, and large-scale production, which greatly restricts the production of soy product enterprises.

[0003] Therefore, in view of this situation, there is an urgent need to develop an automated soy milk residue removal device with an ingenious structural design, automatic waste removal, effective improvement of soy milk residue removal efficiency, and easy promotion, so as to overcome the shortcomings in current practical applications and meet the needs of soy milk production and processing. Utility Model Content

[0004] This utility model provides a soybean milk residue-liquid separator. The structure makes it easy for workers to install and replace the filter cloth, and the circulating filter cloth ensures the filtration effect. At the same time, since the slurry filtration is fully mechanized, it also reduces the labor intensity of workers and greatly improves the production efficiency of soybean product enterprises.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soybean milk residue separator, comprising: a frame, a separation box at the top of the frame, the separation box consisting of a lower cover fixedly connected to the top of the frame and an upper cover hinged to the top of the lower cover; an inlet pipe and a discharge port at opposite ends of the separation box; a drain port and a drain valve at the bottom of the lower cover; a hollow shaft fitted to the outside of the inlet pipe and extending into the separation box; a motor at the bottom of the frame, the motor and the hollow shaft being driven by a belt; a drive disc inside the separation box, the drive disc being connected to the end of the hollow shaft; a driven disc disposed inside the separation box and fitted to the discharge port via a bearing; a scraper disposed between the drive disc and the driven disc, and fixedly connected to the inlet pipe via a bracket; and a discharge trough, one end of which is connected to the top of the scraper, and the other end extending outward from the separation box via the discharge port.

[0006] Preferably, the slurry inlet pipe has a downward-facing elbow at one end corresponding to the inside of the separation box, and the bottom of the elbow is connected to a filter box, the bottom of which is densely covered with a number of filter holes.

[0007] Preferably, the slurry inlet pipe is fixedly connected to the frame; the hollow shaft is provided with a pulley outside the separation box and a connecting flange inside the separation box; the drive disc is connected to the hollow shaft through the connecting flange and has a through hole corresponding to the slurry inlet pipe.

[0008] Preferably, the scraper frame comprises a flat scraper bar corresponding to the top of the slag discharge trough and a plurality of arc-shaped scraper bars distributed above the slurry inlet pipe.

[0009] Preferably, it also includes a jet pipe extending into the interior of the separation chamber.

[0010] The beneficial effects of this invention are as follows: During operation, the operator opens the top cover and places the filter cloth between the drive and driven discs, forming a cylindrical structure. At this point, the top of the scraper is in contact with the filter cloth. During filtration, the upstream equipment pumps the raw liquid to be filtered into the separation tank through the inlet pipe. The motor is then started, causing the filter cloth to rotate. The residue in the soybean milk adheres to the inside of the filter cloth until it encounters the scraper, detaches from the filter cloth, and falls into the slag discharge trough. The inclined slag discharge trough discharges the scraped residue from the separation tank through the discharge port. Once the soybean milk in the separation tank has been filtered, the operator stops the motor and opens the drain valve, thus obtaining filtered, pure soybean milk. This structure facilitates the installation and replacement of the filter cloth, and the cyclical operation of the filter cloth ensures effective slag removal. Furthermore, because filtration is fully mechanized, it reduces the labor intensity of workers and greatly improves the production efficiency of soybean product enterprises. The filter box is used for initial filtration of the soy milk raw material, while also dispersing the flow area of ​​the soy milk raw material and generating more bubbles, which facilitates the capture of residue in the soy milk concentrate by the filter cloth. The flat scraper is used for final scraping of residue from the filter cloth, and the various arc-shaped scrapers facilitate the loosening of residue, thereby improving the filtration effect of the filter cloth. High-pressure air can also be blown into the separation chamber through the air jet pipe, which facilitates the removal of extremely small residues in the soy milk concentrate from the filter cloth, ensuring the filtration effect of the filter cloth.

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a soybean milk residue separator includes: a frame 1, a separation chamber at the top of the frame 1, the separation chamber consisting of a lower cover 3 fixedly connected to the top of the frame 1 and an upper cover 2 hinged to the top of the lower cover 3; an inlet pipe 4 and a residue outlet 5 at opposite ends of the separation chamber; a liquid outlet 6 and a liquid drain valve at the bottom of the lower cover 3; a hollow shaft 7 fitted to the outside of the inlet pipe 4 and extending into the separation chamber; and a motor 9 at the bottom of the frame 1. The hollow shaft 7 is driven by a belt. A drive disc 10 is located inside the separation box and connected to the end of the hollow shaft 7. A driven disc 11 is located inside the separation box and engages with the slag discharge port 5 via a bearing. A scraper is located between the drive disc 10 and the driven disc 11 and is fixedly connected to the slurry inlet pipe 4 via a bracket. A slag discharge trough 12 is connected at one end to the top of the scraper and at the other end to the outside of the separation box via the slag discharge port 5. The slurry inlet pipe 4 is fixedly connected to the frame 1. The hollow shaft 7 has a pulley corresponding to the outside of the separation box and a connecting flange corresponding to the inside of the separation box. The drive disc 10 is connected to the hollow shaft 7 via the connecting flange and has a through hole corresponding to the slurry inlet pipe 4.

[0020] With the above setup, during operation, the operator opens the top cover 2 and places the filter cloth 17 between the drive disc 10 and the driven disc 11, forming a cylindrical structure. At this point, the top of the scraper is in contact with the filter cloth 17. During filtration, the upstream equipment pumps the raw liquid to be filtered through the inlet pipe 4 into the separation tank. The motor 9 is then started, causing the filter cloth 17 to rotate. The residue in the soybean milk adheres to the inside of the filter cloth 17 until it encounters the scraper, at which point it detaches from the filter cloth 17 and falls into the slag discharge trough 12. The inclined slag discharge trough 12 discharges the scraped residue through the slag discharge port 5 into the separation tank. Once the soybean milk in the separation tank has been filtered, the operator stops the motor 9 and opens the drain valve, thus obtaining filtered, pure soybean milk. This structure facilitates the installation and replacement of the filter cloth 17, and the cyclical operation of the filter cloth 17 ensures effective slag removal. Furthermore, because the filtration is fully mechanized, it reduces the labor intensity of workers and greatly improves the production efficiency of soybean product enterprises.

[0021] The slurry inlet pipe 4 has a downward-facing elbow at one end corresponding to the inside of the separation box, and the bottom of the elbow is connected to a filter box 13, the bottom of which is densely covered with a number of filter holes.

[0022] The filter box 13 in this setup is used for initial filtration of the soy milk raw materials, while also dispersing the flow area of ​​the soy milk raw materials and generating more bubbles, which helps the residue in the soy milk concentrate to be captured by the filter cloth 17.

[0023] The scraper frame comprises a flat scraper 14 above the slag discharge trough 12 and multiple arc-shaped scraper 15 distributed above the slurry inlet pipe 4. The flat scraper 14 in this configuration is used to finally scrape off the slag on the filter cloth 17, while the arc-shaped scraper 15 facilitates the loosening of the slag, thereby improving the filtration effect of the filter cloth 17.

[0024] It also includes an air jet pipe 16 extending into the separation chamber. High-pressure air is blown into the separation chamber through the air jet pipe 16, which facilitates the removal of extremely small residues in the soybean milk concentrate from the filter cloth 17, thus ensuring the filtration effect of the filter cloth 17.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
