Description

Technical Field

[0001] This utility model relates to the field of food processing, and in particular to a continuous vacuum concentration device for pork trotter rice noodle soup. Background Technology

[0002] As a popular local delicacy, the flavor and quality of the broth are the core competitive advantages of braised pork trotters with rice noodles. In the broth preparation process, the concentration step plays a crucial role, effectively enhancing the richness of the broth's flavor and extending its shelf life. In existing continuous vacuum concentration equipment for pork trotter rice noodle soup, placing the filter at the outlet is a common practice. However, this design has significant drawbacks in practical applications. After vacuum concentration, the soup becomes much more concentrated and viscous, easily adhering to the filter screen as it passes through the outlet, causing rapid clogging of the filter channel. This not only severely impacts output efficiency and disrupts production, but also requires frequent shutdowns for cleaning. The cleaning process results in a large amount of concentrated soup residue being wasted, significantly increasing production costs. Skipping the filtration process entirely and sending unfiltered broth directly to the concentration process has equally serious consequences. Impurities from the broth will remain in the concentrated broth, directly affecting the product's appearance and taste, reducing product quality and market competitiveness. For example, if consumers find bone fragments in their food, it will severely damage their eating experience and consequently harm the product's reputation. More importantly, some impurities may contain sharp objects. These sharp objects, if introduced into subsequent packaging processes, may damage packaging materials, leading to poor sealing, affecting the product's shelf life, and potentially even causing food safety issues. In view of this, it is necessary to propose an optimized continuous vacuum concentration device for pork trotter rice noodle soup to address the problems mentioned above in the filtration process.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a continuous vacuum concentration device for pork trotter rice noodle soup base, comprising a tank body 1, a tank cover 2 embedded in the top of the tank body 1, and a control unit 4 on the front side of the outer wall of the tank body 1 for operating the device. The tank body 1 has an inner tank 16 and multiple heating wires 15 inside. The multiple heating wires 15 are located between the tank body 1 and the inner tank 16 and are in close contact with the outer wall of the inner tank 16 and are evenly distributed. The tank body 1 is made of heat-insulating material, and the inner tank 16 is made of heat-conducting material. The heating wires 15 are L-shaped and attached to the bottom and sides of the inner tank 16, so that the inner tank 16 is heated evenly around its perimeter and bottom during heating, thereby improving the concentration efficiency. The control unit 4 is electrically connected to the entire device, and the device can be operated through the control unit 4. The control unit 4 is equipped with a temperature sensor, and the heating temperature of the heating wires 15 can be adjusted by setting a temperature controller, thereby facilitating effective heating of the soup base inside the inner tank 16.

[0018] Reference Figure 1 The bottom of the tank body 1 is fixedly connected with four support legs 3. The bottom center of the tank body 1 is provided with a discharge pipe 11, which is equipped with a shut-off valve. The top front side of the tank cover 2 is provided with an air pipe 8, which is equipped with a sealing cap. It is used to open during discharge or feeding to maintain an air pressure balance inside the inner tank 16, ensuring the normal discharge or feeding process.

[0019] Reference Figure 1 - Figure 3 An air pump 9 is connected to the top rear side of the can lid 2, and a pressure gauge 10 is provided on the top right side of the can lid 2. The air pump 9 is used to extract air from the inside of the inner can 16 to keep the inside of the inner can 16 in a vacuum state. The boiling point of water is lowered in a vacuum state, making water easier to evaporate, so as to achieve the purpose of low-temperature concentration of soup ingredients and avoid the loss of a large amount of volatile aroma components in the soup ingredients due to high-temperature heating, which would destroy the nutrients in the soup ingredients and affect the quality of the soup ingredients. The pressure gauge 10 is used to monitor the air pressure inside the inner can 16.

[0020] Reference Figure 1 - Figure 4A feed pipe 7 is provided on the top left side of the can lid 2. The left end of the feed pipe 7 is fixedly connected to the processing box 12. A feed pipe 6 is provided on the left side surface of the processing box 12. The feed pipe 6 is equipped with a shut-off valve. A fixing rod 26 is fixedly connected to the center of the bottom of the inner wall of the processing box 12. A sleeve rod 24 is connected to the fixing rod 26 through a thread on its circumferential surface. A scraper 25 is fixedly connected to the upper side surface of the sleeve rod 24. A circular ring base 23 is rotatably connected to the bottom circumferential surface of the sleeve rod 24. A filter cylinder 20 is rotatably connected to the bottom side wall of the circular ring base 23, and a rubber ring 22 is provided at the connection. The filter cylinder 20 is shaped as a sloping cylinder with a lower left side and a higher right side. The base 23, sleeve rod 24, and scraper 25 are all located inside the filter cylinder 20. The top edge 27 is fixedly connected to the top of the filter cylinder 20. The top edge 27 fits against the inner wall of the processing box 12. A handle 21 is fixedly connected above the top edge 27. The filter cylinder 20 can be moved up and down by the handle 21. When the filter cylinder 20 moves up and down, the sleeve rod 24 will rotate continuously in the ring base 23 through the thread on the fixed rod 26. This drives the scraper 25 to scrape the upper inner wall of the filter cylinder 20, so that the soup residue falls into the bottom of the filter cylinder 20 for preliminary treatment of the soup residue, preventing the soup residue from clogging the upper filter holes and effectively ensuring the filtration efficiency of the soup residue.

[0021] Reference Figure 1 - Figure 4 The top of the processing box 12 is connected to a cover plate 13 by screws. A handle 14 is fixedly connected to the upper surface of the cover plate 13. The cover plate 13 can be opened by the handle 14. After opening, the filter cartridge 20 can be lifted directly by the handle 21 to pour out the soup residue and thoroughly clean the filter cartridge 20. This prevents the soup residue in the filter cartridge 20 from deteriorating and affecting the next concentration process, thus effectively improving the quality of soup production.

[0022] Reference Figure 2 , Figure 3 A motor 5 is fixedly connected to the center of the top of the can lid 2. The output end of the motor 5 is fixedly connected to a rotating shaft 17 through the bottom of the can lid 2. Four scrapers 18 are fixedly connected to the circumferential surface of the rotating shaft 17. The four scrapers 18 can fit against the inner wall of the inner can 16. Multiple stirring paddles 19 are fixedly connected to the side of the four scrapers 18 near the rotating shaft 17, which can stir the soup inside the inner can 16. During concentration, the soup can fully contact the inner walls and bottom of the inner can 16, increasing the contact area between the soup and the inner wall of the inner can 16, and further improving the original uniformity of heating.

[0023] Working principle: During use, open the shut-off valve of the feed pipe 6 and the sealing cap of the air pipe 8, and close the shut-off valve of the discharge pipe 11. The rice noodle soup is then introduced into the processing tank 12 through the feed pipe 6 for filtration. The filtered soup residue will automatically fall to the bottom of the filter cylinder 20. The filtered soup will then enter the inner tank 16 through the feed pipe 7. At this time, the shut-off valve of the feed pipe 6 and the sealing cap of the air pipe 8 are closed, keeping the inner tank 16 sealed. The control unit 4 activates the air pump 9, heating wire 15, and motor 5. The air pump 9 then circulates the air through the inner tank 16. The interior is vacuumed; the soup in the inner tank 16 is heated and concentrated by heating wire 15; the motor 5 drives the rotating shaft 17 to rotate scraper 18 and stirring paddle 19 together. The stirring paddle 19 can continuously stir the soup inside the inner tank 16, and the scraper 18 can continuously scrape the inner wall of the inner tank 16 to prevent the soup from sticking to the inner wall of the inner tank 16 during vacuum heating and concentration. After the soup is concentrated, the sealing cover of the air pipe 8 can be opened to keep the air pressure inside and outside the inner tank 16 balanced, and the shut-off valve of the discharge pipe 11 can be opened to discharge the concentrated soup.

[0024] During the feeding process, the cover plate 13 can be opened, and the filter cylinder 20 can be moved up and down by the handle 21. The sleeve rod 24 will rotate continuously in the ring base 23 due to the thread on the fixing rod 26, which will drive the scraper 25 to scrape the upper inner wall of the filter cylinder 20, so that the soup residue falls into the bottom of the filter cylinder 20 for preliminary treatment of the soup residue and to prevent the soup residue from clogging the upper filter holes. After the soup is concentrated, the filter cylinder 20 can be lifted out directly, the soup residue can be poured out, and the filter cylinder 20 can be cleaned.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
