Description

Technical Field

[0001] The invention belongs to the technical field of energy utilization, and in particular relates to a system and method for rapidly boiling and cooling edible oil at high temperature. Background Art

[0002] In the food processing process, edible oil is an essential ingredient and must be heated to a high temperature before use. Existing methods for boiling edible oil at high temperatures involve first transferring room-temperature oil to an oil pan, heating it to the required temperature of 160°C or higher using gas, and then pumping the high-temperature oil to a wok. Two boiling pans are used alternately to achieve continuous production. Generally, to minimize disruption to actual processing, excess high-temperature oil is often prepared. This results in a large amount of excess oil remaining after processing. However, high-temperature oil easily oxidizes over time, degrading its quality. Existing methods for cooling edible high-temperature oil involve pumping the boiled oil to an open cooling tank, which is equipped with spiral blades to stir the oil and allow it to cool naturally. Consequently, both the boiling and cooling processes suffer from high energy consumption and low efficiency. Furthermore, the natural cooling method can easily cause oxidation of the oil, leading to heat loss and very low efficiency.

[0027] Then the first heated oil is introduced into the boiling pot and heated to above 180°C. Finally, the heated oil is directly introduced into the high-temperature tank for use in the frying equipment.

[0028] When cooling hot oil, first introduce the cooled heat exchange medium into the heat exchange device, and then introduce the hot oil into the heat exchange device for heat exchange. The oil is cooled to 40℃-50℃ and introduced into the temporary storage tank for temporary storage for filling.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. By connecting the tank and the pipeline to transport the edible oil, rapid transportation can be achieved when the edible oil is boiled or cooled. When the high-temperature oil flows in the pipeline and the tank, the contact with the outside air is reduced, thereby reducing oxidation. The use of a heat exchange device to exchange heat for the edible oil can achieve rapid cooling and heating of the edible oil. In addition, the heat can be replaced and recovered during the cooling process and can be used in other places, thereby improving the utilization rate of thermal energy.

[0031] 2. By setting up a gas source device on the high-temperature tank, nitrogen can be filled into the high-temperature tank for anti-oxidation protection, and the generated flue gas can be squeezed out by the nitrogen, and the flue gas can be adsorbed and condensed by the adsorption device to reduce emissions to the outside.

[0032] 3. By setting up a circulation loop of the first bypass pipe and the second bypass pipe, the normal temperature oil in the normal temperature tank can be self-circulated, especially when passing through the heat exchange device, simple heat exchange is performed, reducing the situation where the oil condenses and the fluidity decreases when the temperature drops. In addition, the filter component set on the heat exchange device can filter the oil and reduce impurities in the oil; it can also reduce the clogging and deposition of impurities on the heat exchange device, thereby improving the heat exchange efficiency between the heat exchange medium and the oil.

[0033] 4. The filter assembly can filter the oil entering the heat exchange tube, which not only ensures the cleanliness of the oil, reduces oil oxidation, but also avoids clogging in the heat exchange tube. In addition, when the adjustment table and the filter assembly are connected by the sleeve rod and the spring, the position of the filter assembly can be changed according to the direction of oil inlet on the heat exchange device. In particular, the movable ring can be opened or closed according to the flow direction of different oil under the driving action of the blade. When the movable ring is opened, the filter screen plays a filtering role. When the movable ring is closed, the flow will first have an impact on the filter screen due to the blocking effect of the groove on the protrusion, thereby achieving backwash on the filter screen, and the filtered impurities on the filter screen are flushed into the large cavity of the protrusion. Moreover, as the pressure increases, the blades are pushed and the movable ring is completely closed, making the entire filter assembly act as a baffle. The impurities flushed into the large cavity of the protrusion can be discharged outward through the drain pipe, thereby achieving the purpose of oil filtering and self-cleaning when the oil is fed from different directions.

[0044] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0045] like Figures 1-9 As shown, the specific scheme of this embodiment is: a system for rapidly boiling and cooling edible oil at high temperature, comprising a normal temperature tank 10, a high temperature tank 11 and a boiling pot 12, wherein the discharge end of the normal temperature tank 10 is connected to a heat exchange device 14, and the discharge end of the heat exchange device 14 is respectively connected to the boiling pot 12 and the temporary storage tank 13, and the discharge end of the boiling pot 12 is connected to the high temperature tank 11. Figure 1 As shown, the normal temperature tank 10, the high temperature tank 11, the boiling pot 12, the temporary storage tank 13, and the heat exchange device 14 are all connected by pipes, and various valve bodies are arranged on the pipes. The specific connection is based on actual needs, which will not be described here.

[0046] The heat exchange device 14 is provided with a plurality of pipes for facilitating the replacement of the input heat exchange medium. In this embodiment, the input heat exchange medium is cooling water for cooling the high-temperature oil and high-temperature steam for heating the normal-temperature oil, and is connected to the medium inlet of the heat exchange device 14 through different input pipes. In this solution, when heating the normal-temperature oil, the normal-temperature oil in the normal-temperature tank 10 is heated by the heat exchange device 14 and then output to the boiling pot 12 for further heating to the required temperature. In this way, two-step heating can be achieved, thereby improving the efficiency of high-temperature oil preparation and saving time. The hot oil in the high-temperature tank 11 is directly output for use. The output is connected to the frying system through a pipeline, which is not shown in the accompanying drawings, or the hot oil is cooled by the heat exchange device 14 and stored in the temporary storage tank 13 for filling. After the high-temperature oil is cooled by the heat exchange device 14, it can heat the cooling water, and the heated cooling water can also recover heat, which has a higher energy utilization rate. From the overall solution, edible oil is transported and stored in sealed pipes and tanks, which can greatly reduce the contact between oil and air, especially for oil heated at high temperature, which can reduce the oxidation of edible oil.

[0047] like Figure 2 、 Figure 8 、 Figure 9 As shown, as a preferred embodiment of the above embodiment, the top of the high-temperature tank 11 is connected to a gas source device 15 and an adsorption device 16 for adsorbing the high-temperature flue gas in the high-temperature tank 11 through pipelines. The gas source device 15 introduces protective gas into the high-temperature tank 11. Specifically, the protective gas filled in the gas source device 15 is nitrogen. Nitrogen is introduced into the high-temperature tank 11 to discharge the air in the high-temperature tank 11, reduce the oxidation of edible oil, and improve the quality of the oil. The adsorption device 16 is mainly provided to adsorb the high-temperature oil smoke discharged by the nitrogen to reduce emissions to the external environment.

[0048] Specifically, a first one-way valve 17 is respectively provided on the pipeline connecting the gas source device 15 and the adsorption device 16 to the high-temperature tank 11, and a pressure relief valve 18 is also provided on the pipeline connecting the adsorption device 16 to the high-temperature tank 11. The pressure relief valve 18 is mainly opened when nitrogen is filled into the high-temperature tank 11 and the air pressure increases, so that the high-temperature flue gas and excess air can be discharged. Among them, the adsorption device 16 includes a box body 161, and an adsorption chamber 162 connected to the high-temperature tank 11 is provided in the box body 161. The first adsorption plate 163 and the second adsorption plate 164 arranged at intervals from each other are detachably provided in the adsorption chamber 162. The first adsorption plate 163 and the second adsorption plate 164 are respectively connected to a power supply to form an electric field. The adsorption chamber 162 is also filled with a filter element 166, such as Figure 8As shown, the first adsorption plate 163 is connected to the positive electrode, and the second adsorption plate 164 is connected to the negative electrode, thereby forming an electric field between the first adsorption plate 163 and the second adsorption plate 164. Under the action of the electric field, the high-temperature flue gas can be adsorbed, and the filter element 166 mainly plays a filtering role and adopts a high-temperature resistant filter element; the first adsorption plate 163 and the second adsorption plate 164 are hollow inside and are connected to a water pipe 165 for circulating coolant. Cooling water is introduced into the first adsorption plate 163 and the second adsorption plate 164 through the water pipe 165, which can cool the flue gas and accelerate the condensation of oil smoke.

[0049] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 As shown, as a preferred embodiment of the above embodiment, the oil pipeline of the normal temperature tank 10 is connected to the oil outlet end of the heat exchange device 14 through a first bypass pipe 19, and the oil inlet end of the heat exchange device 14 is connected to the oil inlet pipe of the normal temperature tank 10 through a second bypass pipe 20, forming a circulation loop between the normal temperature tank 10 and the heat exchange device 14; the first bypass pipe 19 and the second bypass pipe 20 are respectively provided with control valves, and the first bypass pipe 19 and the second bypass pipe 20 are provided as auxiliary pipes, the purpose of which is to realize the self-circulation flow of the normal temperature oil in the normal temperature tank 10, especially in a low temperature environment, the normal temperature oil can be introduced into the heat exchange device 14 for simple heating treatment, thereby increasing the fluidity of the normal temperature oil and reducing condensation.

[0050] As a preferred embodiment of the above embodiment, the heat exchange device 14 includes an outer shell 1401 and a plurality of heat exchange tubes 1402 arranged inside the outer shell 1401. Specifically, a plurality of heat-conducting fins are arranged on the heat exchange tubes 1402, and the heat-conducting fins are spiral-shaped. The outer shell 1401 and the heat exchange tubes 1402 are isolated from each other and not connected to each other. When heat exchange is performed, the oil passes through the inside of the heat exchange tubes 1402, and the heat exchange medium passes through the outer shell 1401, completely wrapping the heat exchange tubes 1402, thereby completing the hot and cold exchange between the oil and the heat exchange medium. An interface 1403 is provided on the outer shell 1401, one of which is connected to the input heat exchange medium pipeline, and the pipeline connected to the other interface 1403 discharges the medium after heat exchange.

[0051] In order to further improve the efficiency of heat exchange, in this embodiment, a plurality of heat conducting plates 1404 in contact with the heat exchange tubes 1402 are provided inside the outer shell 1401, and a plurality of flow guide ports 1405 opening toward the outer surface of the heat exchange tubes 1402 are also provided on the heat conducting plates 1404. Figure 4As shown, when the heat exchange medium passes through the guide port 1405, under the guidance of the guide port 1405, the heat exchange medium can be directed toward the surface of the heat exchange tube 1402, thereby forming turbulence on the surface of the heat exchange tube 1402 and increasing the heat exchange efficiency.

[0052] As a preferred embodiment of the above, both ends of the outer shell 1401 are connected with connectors 1406, the connector 1406 is connected with a connecting pipe 1407, the connecting pipe 1407 is connected with a pipeline 1408, the pipeline 1408 is provided with two branches connected with the connecting pipe 1407, and each branch is provided with a second one-way valve 1409. Figure 3 As shown, the pipeline 1408 is symmetrically arranged at both ends of the connecting head 1406 and the connecting pipe 1407, and the flow direction of the branch pipe close to the connecting head 1406 is outward, and the flow direction of the other branch pipe is inward; a filter component 1410 is movably provided in the inner cavity of the connecting pipe 1407 for facilitating filtering of the oil. The filter component 1410 is mainly used to filter the oil, which can avoid impurities from causing blockage when passing through the heat exchange tube 1402, and can also reduce the quality change of the oil caused by oxidation of impurities after high-temperature frying.

[0053] An adjustable seal is provided in the connecting tube 1407 with an adjustment platform 1411. Specifically, the adjustment platform 1411 and the connecting tube 1407 are threadedly connected to each other, and a sealing ring is provided between the two. A sliding sleeve is provided on the adjustment platform 1411 and is movable with the filter assembly 1410. A spring is provided in the sliding sleeve to facilitate the elastic movement of the filter assembly 1410. Specifically, the central axis of the filter assembly 1410 is inserted into the sliding sleeve, and the two cannot rotate with each other and can only slide with each other along the axial direction. Therefore, under the action of the spring in the sliding sleeve, the filter assembly 1410 can be driven to reciprocate in the connecting tube 1407; Figure 5 As shown, a stepped chamber is provided in the connecting pipe 1407, and the filter assembly 1410 moves only within the chamber communicating with the connector 1406, and the range of movement of the filter assembly 1410 is only on both sides of the branch pipe of the pipeline 1408 close to the connector 1406, so as to attach Figure 3 、 5Taking the up, down, left and right directions as an example, when the oil in the left side pipe 1408 of the heat exchange tube 1402 flows out of the heat exchange device 14, the filter assembly 1410 on the left is squeezed toward the adjustment platform 1411, and the filter assembly 1410 will retract toward the side of the adjustment platform 1411, and the branch pipe close to the connector 1406 is directly connected to the small chamber on the connecting pipe 1407, while the flow direction in the pipe 1408 on the right side of the heat exchange tube 1402 is toward the heat exchange device 14, and flows into the inner cavity of the connecting pipe 1407 through the branch pipe away from the side of the connector 1406, thereby generating a thrust toward the side of the heat exchange tube 1402 on the filter assembly 1410. At this time, the filter assembly 1410 on the right side will filter the oil. Therefore, as long as the pipeline 1408 on which side of the heat exchange tube 1402 belongs to the oil input end, the filter assembly 1410 at this end will play a filtering role. Since the filter assembly 1410 at the other end is pushed toward the side of the adjustment platform 1411 by the oil pressure, the impurities filtered on the filter assembly 1410 can be discharged through the backflushing effect. Therefore, when oil is input into one of the pipelines 1408, the filter assembly 1410 at one input end plays a filtering role, and the filter assembly 1410 at the other end is backflushed to play a self-cleaning role; the backflushed impurities flow into the large chamber of the connecting pipe 1407.

[0054] In order to remove the impurities cleaned by backwashing on the filter component 1410, in this embodiment, a drain pipe 1412 is also provided on the connecting pipe 1407. The drain pipe 1412 is connected to the largest chamber in the connecting pipe 1407, and the drain pipe 1412 is connected to an accumulator 1413 and an electric control valve 1414. The specific arrangement of the accumulator 1413 allows the oil in the largest chamber in the connecting pipe 1407 to flow. The accumulator 1413 is provided with a pressure sensor 14131. The pressure detected by the pressure sensor 14131 is used as a control signal for the electric control valve 1414 to be energized and opened. When the pressure sensor 14131 detects that the pressure value exceeds the set value and is a stable pressure value, it sends a signal to the controller, and the controller then controls the electric control valve 1414 to be energized and opened. After the drain pipe 1412 is opened, the impurities in the connecting pipe 1407 can be discharged to the outside.

[0055] like Figure 6 、 Figure 7As shown, as a preferred embodiment of the above embodiment, the filter assembly 1410 includes a support ring 14101 interconnected with the adjustment platform 1411, that is, the central axis of the support ring 14101 is inserted into the sleeve rod on the adjustment platform 1411, and a movable ring 14102 is provided on one side of the support ring 14101, and a filter screen 14103 for filtering edible oil is provided between the support ring 14101 and the movable ring 14102, and a blade 14104 is also provided at the end of the movable ring 14102, and the movable ring 14102 and the blade 14104 are fixed to each other and can rotate synchronously; a groove 14105 is provided on the central axis of the support ring 14101, and a protrusion 14107 that can extend into the groove 14105 is provided on the movable ring 14102, and a rebound member 14106 that can push the protrusion 14107 to rotate and reset is provided in the groove 14105, and the rebound member 14106 can be selected from a spring or a shrapnel , which can limit the rotation of the support ring 14101 and the movable ring 14102 within a certain range; therefore, in terms of the overall solution of the filter assembly 1410, when one side of the blade 14104 is pushed by the positive oil, the blade 14104 will rotate under the action of the oil pressure, thereby driving the movable ring 14102 to rotate, and under the push of the rebound part 14106, the movable ring 14102 can slowly cover the filter screen 14103. In the process of slowly covering, the oil pressure will backwash away the impurities on the filter screen 14103. Until the movable ring 14102 completely covers the filter screen 14103, the support ring 14101 and the movable ring 14102 are equivalent to completely blocking the position of the filter holes of the filter screen 14103, thereby completely forming a plate-like structure, which only serves as a partition to reduce the continuous flow of oil to the position with impurities, so as to facilitate the subsequent discharge of impurities.

[0056] In addition, the present application also provides a method for completing high-temperature cooking and cooling of edible oil using the above edible oil rapid high-temperature cooking and cooling system. Specifically,

[0057] When boiling hot oil, the heated heat exchange medium is first introduced into the heat exchange device 14, and then the room temperature edible oil in the room temperature tank 10 is introduced into the heat exchange device 14 for heat exchange, and the oil is heated to 100°C-120°C, completing the first heating; then the first heated oil is introduced into the boiling pot 12 and heated to above 180°C, and finally the heated oil is directly introduced into the high temperature tank 11 for use in the frying equipment;

[0058] When cooling hot oil, the cooled heat exchange medium is first introduced into the heat exchange device 14, and the hot oil is then introduced into the heat exchange device 14 for heat exchange. The oil is cooled to 40°C-50°C and introduced into the temporary storage tank 13 for temporary storage for filling. After the heat exchange, the temperature of the cold heat exchange medium increases and can be used for other purposes.
