Description

Technical Field

[0001] This application relates to the field of edible oil processing technology, and in particular to a circulating water cooling device. Background Technology

[0002] In edible oil processing, after many high-temperature treatment steps, it is necessary to quickly and safely cool the oil to the target temperature. For example, in the deacidification process, the oil temperature is high after deacidification and needs to be cooled quickly to prevent oil deterioration; in the decolorization process, the oil temperature rises after decolorization and needs to be cooled to a suitable temperature for subsequent processing; in the post-refining cooling process, the refined oil is usually at a high temperature and needs to be cooled to the packaging temperature to ensure oil quality stability.

[0003] Currently, the cooling process for cooking oil involves either stirring the oil and using a fan to expedite the cooling process, or immersing the oil tank directly in a water bath. Both methods have relatively low cooling efficiency and therefore require further improvement. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a circulating water cooling device to solve the problems in the prior art.

[0005] The circulating water cooling device provided in this application adopts the following technical solution: A circulating water cooling device includes a plate heat exchanger, a cooling tower, a water tank, and a circulating water pump; the cooling tower, water tank, and circulating water pump form a circulating water circuit with the cold fluid inlet and cold fluid outlet of the plate heat exchanger through pipelines; the hot fluid inlet and hot fluid outlet of the plate heat exchanger are for the inflow and outflow of high-temperature edible oil from the outside.

[0006] By adopting the above technical solution, when high-temperature edible oil needs to be cooled during edible oil processing, a cooling tower, water tank, and circulating water pump are used to form a circulating water circuit between the cold fluid inlet and cold fluid outlet of the plate heat exchanger through pipelines. The high-temperature edible oil flows into the plate heat exchanger through the hot fluid inlet, exchanges heat with the cold water flowing into the plate heat exchanger to cool it down, and then flows out through the hot fluid outlet to cool the high-temperature edible oil. The cooling efficiency is high.

[0007] Optionally, a partition is provided in the middle of the water tank to divide the interior of the water tank into a return water zone and a water outlet zone. The top of the partition is lower than the top edge of the water tank so that the top of the return water zone and the top of the water outlet zone are connected. The water cooled by the cooling tower flows to the return water zone, and the water in the water outlet zone flows to the plate heat exchanger.

[0008] Optionally, the bottom of the water tank is provided with a drain outlet in both the return water area and the outlet water area, and a drain valve is installed on the drain outlet.

[0009] By adopting the above technical solution and setting up sewage outlets and sewage valves, it is convenient to carry out sewage treatment during the subsequent cleaning process.

[0010] Optionally, the bottom of the return water zone and the outlet water zone is conical.

[0011] By adopting the above technical solution, the bottom of the return water area and the outlet water area are designed in a cone shape, which can prevent mud accumulation and blockage and improve cleaning efficiency.

[0012] Optionally, a removable filter screen is installed in the water outlet area. The filter screen is used for vertical filtration, and the inner side of the filter screen is lower than the top of the partition, while the outer side of the filter screen is angled downwards.

[0013] By adopting the above technical solution, the top of the water tank is designed to be open and unsealed to ensure its own heat dissipation capacity. This open structure makes it easy for external debris to fall in. However, by installing a filter screen in the outlet area, this debris can be filtered out, preventing it from flowing into the plate heat exchanger and causing blockages. Furthermore, when water in the return water area flows into the outlet area through the opening at the top of the baffle, the filter screen's guiding effect expands the water flow area, further increasing its heat dissipation efficiency.

[0014] Optionally, the outer side of the filter screen has an upward-curving conical opening, and both the front and rear sides of the conical opening are sealed. The front and rear sides of the conical opening, as well as the outer side, are all tightly attached to the inner wall of the return water zone.

[0015] By adopting the above technical solution, during the filtration process, the filtered debris can flow downwards into the conical opening on the outer side of the filter screen for collection, making it easier to remove the filter screen for cleaning. Without this conical opening structure, debris on the filter screen would easily fall into the outlet area during removal.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to cool down the high-temperature edible oil during edible oil processing, a cooling tower, water tank, and circulating water pump are used to form a circulating water circuit between the cold fluid inlet and cold fluid outlet of the plate heat exchanger through pipelines. The high-temperature edible oil flows into the plate heat exchanger through the hot fluid inlet, exchanges heat with the cold water flowing into the plate heat exchanger to cool down, and then flows out through the hot fluid outlet to cool down the high-temperature edible oil. Its cooling efficiency is high. 2. The bottom of the return water area and the outlet water area are designed in a cone shape to prevent mud accumulation and blockage, and to improve cleaning efficiency; 3. To ensure the water tank's own heat dissipation capacity, its top is designed to be open and unsealed. This open structure makes it easy for external debris to fall in. However, by installing a filter screen in the outlet area, this debris can be filtered out, preventing it from flowing into the plate heat exchanger and causing blockages. Furthermore, when water from the return water area flows into the outlet area through the opening at the top of the baffle, the filter screen's guiding effect expands the water flow area, further increasing its heat dissipation efficiency. 4. During the filtration process, the filtered debris flows downwards into the conical opening on the outer side of the filter screen for collection, making it easy to remove the filter screen for cleaning. Without this conical opening, debris on the filter screen would easily fall into the water outlet area during removal. Attached Figure Description

[0020] 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.

[0021] like Figures 1 to 2 As shown, the present invention provides a circulating water cooling device, including a plate heat exchanger 1, a cooling tower 2, a water tank 3, and a circulating water pump 4; wherein, the cooling tower 2, the water tank 3, and the circulating water pump 4 form a circulating water circuit through pipelines with the cold fluid inlet and cold fluid outlet of the plate heat exchanger 1, and the hot fluid inlet and hot fluid outlet of the plate heat exchanger 1 are for the inflow and outflow of high-temperature edible oil from the outside.

[0022] When edible oil processing requires cooling of high-temperature edible oil, a circulating water circuit is formed between the cooling tower 2, water tank 3, and circulating water pump 4 and the cold fluid inlet and cold fluid outlet of the plate heat exchanger 1 through pipelines. The high-temperature edible oil flows into the plate heat exchanger 1 through the hot fluid inlet, exchanges heat with the cold water flowing into the plate heat exchanger 1 to cool down, and then flows out through the hot fluid outlet to cool down the high-temperature edible oil. The cooling efficiency is high.

[0023] In this embodiment, a partition 31 is provided in the middle of the water tank 3. The top of the partition 31 is lower than the top edge of the water tank 3, dividing the interior of the water tank 3 into two areas: a return water area 32 and an outlet water area 33. The tops of the return water area 32 and the outlet water area 33 are connected. During operation, the water cooled by the cooling tower 2 flows to the return water area 32, and the water in the outlet water area 33 flows to the plate heat exchanger 1.

[0024] The bottom of the water tank 3 has drain ports at both the return water area 32 and the outlet water area 33, and drain valves 34 are installed on the drain ports. During subsequent cleaning, the drain ports and drain valves 34 can be used to drain waste, which facilitates subsequent cleaning work.

[0025] In this embodiment, the bottom of the return water zone 32 and the outlet water zone 33 is conical, which can prevent sludge accumulation and blockage and improve cleaning efficiency.

[0026] In this embodiment, a removable filter screen 35 is installed in the water outlet zone 33. The filter screen 35 is used for vertical filtration, and the inner side of the filter screen 35 is lower than the top of the partition plate 31, while the outer side of the filter screen 35 is angled downwards. The outer side of the filter screen 35 has an upward-curving conical opening 351, and both the front and rear sides of the conical opening 351 are sealed. The front and rear sides and the outer side of the conical opening 351 are all tightly attached to the inner wall of the return water zone 32.

[0027] To ensure the heat dissipation capacity of the water tank 3, its top is designed to be open and unsealed. This open structure makes it easy for external debris to fall in. However, by installing a filter screen 35 in the outlet area 33, this debris can be filtered out, preventing it from flowing into the plate heat exchanger 1 through the outlet of the outlet area 33 and causing blockage. Furthermore, this single-sided filtration method ensures that the top of the return water area 32 remains open, maximizing its heat dissipation effect. Additionally, when water from the return water area 32 flows into the outlet area 33 through the opening at the top of the baffle 31, the filter screen 35 guides the flow, increasing the water surface area and further enhancing its heat dissipation efficiency.

[0028] In addition, during the filtration process, the filtered debris can flow downwards into the conical opening 351 on the outer side of the filter screen 35 for collection, making it easier to remove the filter screen 35 for cleaning. Without this conical opening 351 structure, the debris on the filter screen 35 would easily fall into the water outlet area 33 during the removal of the filter screen 35.

[0029] Specifically, in this embodiment, support blocks 36 are fixedly provided on the inner wall of the water outlet zone 33 and the side wall of the partition 31 to support the filter screen 35, so as to form a removable installation method.

[0030] The working principle of the circulating water cooling device disclosed in this application is as follows: When high-temperature edible oil needs to be cooled during edible oil processing, a circulating water circuit is formed between the cooling tower 2, water tank 3, and circulating water pump 4 through pipelines and the cold fluid inlet and cold fluid outlet of the plate heat exchanger 1. The high-temperature edible oil flows into the plate heat exchanger 1 through the hot fluid inlet and exchanges heat with the cold water flowing into the plate heat exchanger 1 to cool it down. Then it flows out through the hot fluid outlet to cool the high-temperature edible oil. The cooling efficiency is high.
