Description

Technical Field

[0001] This utility model relates to the technical field of quick-frozen vegetable processing equipment, specifically, to a cooling system for quick-frozen vegetable processing. Background Technology

[0002] Quick-frozen vegetables typically refer to vegetables whose core temperature must drop from -1 degree Celsius to -5 degrees Celsius and then to below -15 degrees Celsius within 30 minutes during freezing.

[0003] The current processing steps for quick-frozen vegetables generally involve washing and removing impurities, blanching and sterilizing, cooling, quick-freezing, sorting, packaging, and warehousing before shipment. Taking sweet corn as an example, low-temperature water is output from an ice water tank to cool the blanched corn kernels. The heated water then re-enters the ice water tank for heat exchange, achieving water recycling. However, as the circulating water continuously washes over the corn kernels, it changes from clear water to turbid water containing starch and other substances, causing water pollution and increasing the risk of bacterial growth on the corn kernels, thus reducing the safety of sweet corn for consumption. Simultaneously, the increase in other impurities in the circulating water easily adheres to the inner wall of the circulating water delivery pipes, leading to reduced water delivery efficiency and even blockage. Impurities adhering to the outer wall of the heat exchange components reduce the heat exchange efficiency of the circulating water, decreasing the effectiveness of the ice water tank and increasing its energy consumption. Therefore, improvements and optimizations to the existing technology are necessary. Utility Model Content

In use, taking sweet corn kernels as an example, the raw material is blanched and sterilized before being transported to the feed end of the chute. The ice water tank is activated to output cooling water. The cooling water is pumped to the feed end of the chute via a built-in pump. Under the influence of gravity, the cooling water and the raw material gradually move downwards along the inclined chute, cooling the raw material and simultaneously rinsing it to improve its cleanliness. Raw materials and cooling water are guided into the draining system through chute one. The draining system can be any existing solid-liquid separation equipment or component, such as a screen or screen cylinder, to separate the raw materials and cooling water.

Fresh clean water is replenished into the ice water pool to ensure continuous cooling operations. This prevents used cooling water from flowing back into the ice water pool, which would increase the impurity content of the cooling water, reduce the water quality, and affect the working efficiency of the ice water pool.

[0053] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0054] Example 1, refer to Figures 1-3 This is the first embodiment of the present invention, which proposes a cooling system for quick-frozen vegetable processing.

[0055] In this embodiment, the cooling system includes a base frame 1, an ice water tank 2, a chute 3, a drain component 4, a water storage tank 5, and a drain pipe 6. In use, taking sweet corn kernels as an example, the raw material is blanched and sterilized before being transported to the feed end of the chute 3. The ice water tank 2 is started to output cooling water. The cooling water is transported to the feed end of the chute 3 through a built-in water pump. Under the action of their own gravity, the cooling water and the raw material gradually move downward along the inclined chute 3. The cooling water cools the raw material and washes it at the same time, improving the cleanliness of the raw material. Raw materials and cooling water are guided into the draining component 4 through the chute 3. The draining component 4 can be any existing solid-liquid separation equipment or component, such as a screen or screen cylinder, to separate the raw materials and cooling water. The cooling water falls into the water collection chamber at the lower end of the draining component 4, while the raw materials are collected and transported to the next processing step. The cooling water collected in the water collection chamber is transported to the water storage tank 5 through the drain pipe 6 and then transported to other processes for reuse. Fresh clean water is replenished into the ice water pool 2 to ensure the continuous operation of the cooling process. This prevents the cooling water that has been used once from flowing back into the ice water pool 2, which would increase the impurity content in the cooling water, reduce the water quality, and affect the working efficiency of the ice water pool 2.

[0056] Example 2, refer to Figures 1-3 This is the second embodiment of the present invention. Based on the first embodiment, this embodiment further adds a second chute 7, a first water supply pipe 8, a first filter element 9, a second water supply pipe 11, and a first conveyor belt 10. It also adds a second filter element 12, a second conveyor belt 13, and a second drain pipe 14. Additionally, it adds a spray element 15, a spray pipe 16, and a spray nozzle 17.

[0057] Taking sweet corn kernels as an example, the working process is explained as follows: When using the product, the raw material is first blanched and sterilized, and then conveyed to conveyor belt 2 13. Conveyor belt 2 13 is a perforated mesh belt in the existing technology, and water leakage holes 2 are opened on conveyor belt 2 13. Conveyor belt 2 13 conveys the raw material to the feed end of chute 2 7.

[0058] The cooling water in the water collection chamber at the lower end of the draining component 4 has two main destinations. The first destination is through the spray pipe 16 and the built-in power source, which transports the cooling water in the water collection chamber at the lower end of the draining component 4 to the spray component 15. The cooling water is then sprayed onto the raw material that has just finished the blanching operation through several spray nozzles 17 to perform preliminary cooling on the raw material. After cooling is completed, this part of the cooling water is guided and collected in the filter component 2 12 and transported to the water storage tank 5 through the drain pipe 2 14. The second destination is where the cooling water in the water collection chamber is transported to the feed end of the chute 7 via the water supply pipe 211 and the built-in power source. This cools and washes the raw materials entering the chute 7, and the flow of the cooling water drives the transport of the raw materials. The cooling water's enveloping transport of the raw materials reduces wear and tear during transport. Along the chute 7, the cooling water and raw materials are transported to the conveyor belt 10, which uses a perforated mesh belt and has drainage holes. The conveyor belt 10 transports the raw materials to the feed end of the chute 3. The cooling water output from the chute 7 is collected by the filter element 9 and transported to the water storage tank 5 via the drain pipe 6, thus completing the use of the cooling water.

[0059] The raw materials entering the feed end of chute 13 are transported into the draining component 4 by the cooling water output from water supply pipe 8 for solid-liquid separation. Throughout the process, the temperature of the cooling water output from ice water tank 2 is defined as A, the temperature of the cooling water in the water collection chamber at the lower end of draining component 4 is defined as B, and the temperature of the cooling water output from the discharge end of chute 27 is defined as C, therefore C > B > A. The temperature of the raw materials immediately after blanching is defined as H. After being sprayed by spray component 15, the temperature of the raw materials is defined as I. The temperature of the raw materials cooled by chute 27 and falling onto conveyor belt 10 is defined as J. The temperature of the raw materials cooled by chute 13 and falling onto draining component 4 is defined as K, therefore H > I > J > K. The cooling water flows through chute 13, draining component 4, chute 27, and water storage tank 5, improving the cooling effect and reducing the energy consumption of ice water tank 2.

[0060] Example 3, refer to Figures 1-3 This is the third embodiment of the present invention. Based on the second embodiment, in order to further improve the utilization rate of cooling water, this embodiment is further improved by adding a belt-type scalding machine 18 and a sealing cover 19, as well as a filter element 3 21, a conveyor belt 3 22 and a drain pipe 3 23, a drum washing machine 24 and a lift pump 25, and a water supply pipe 3 26 and a water supply pipe 4 27.

[0061] The cooling water entering the water storage tank 5 can be utilized in several ways. The first method involves transporting the cooling water to the drum washer 24 via the built-in water supply pipe 5 and a power source to clean and rinse the raw materials, improving their cleanliness. The drum washer 24 is a commonly used cleaning device in existing technology. After cleaning the raw materials, the drum washer 24 collects them into a conical collecting device, the lower end of which is connected to the water supply pipe 26.

[0062] The second method of utilizing cooling water involves using water supply pipe 26 to carry raw materials into lift pump 25. Lift pump 25 and water supply pipe 27 (fourth type) then transport the materials to conveyor belt 22. Lift pump 25 is a centrifugal pump, a technology currently available. As the cooling water flows through water supply pipes 26 and 27, it washes the raw materials, reducing impurities and dust, and improving the cleaning effect. Conveyor belt 22 is a perforated mesh belt, with drainage holes 3. Conveyor belt 22 transports the raw materials to the inlet of belt-type blanching machine 18. Cooling water is collected through drainage holes 3 at filter element 21 and then flows back to water storage tank 5 via drain pipe 23. These two methods improve the utilization rate of cooling water and reduce water waste.

[0063] The raw materials are blanched and sterilized on the belt blanching machine 18. The sealing cover 19 forms an independent sealed space to reduce the escape of high-temperature steam and reduce the consumption of steam energy. At the same time, the steam is drained through the steam outlet pipe 20 on the sealing cover 19 to avoid the formation of condensation on the inner wall of the sealing cover 19, reduce the risk of bacterial growth, and increase the effect of disinfection and sterilization.

[0064] Example 4, refer to Figures 1-3 This is the second embodiment of the present invention. Based on the first embodiment, this embodiment further adds an isolation wall 28. The added isolation wall 28 divides the water storage tank 5 into at least two chambers: the first chamber is a sedimentation chamber, and the second chamber is a circulation chamber. Cooling water is first transported to the sedimentation chamber for sedimentation. The isolation wall 28 acts as an overflow plate. When the liquid level of the cooling water in the sedimentation chamber exceeds the height of the isolation wall 28, the clearer cooling water enters the circulation chamber for reuse. Several isolation walls 28 are used, resulting in several sedimentation chambers. The cooling water undergoes multiple sedimentation processes to obtain clear, reusable cooling water.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
