Description

Technical Field

[0001] The utility model belongs to the field of edible oil cooling circulation system, in particular to an energy-saving edible oil cooling double circulation system. Background Art

[0002] During the filling process of small-packaged edible oil, the temperature of the edible oil must be controlled (the optimal filling oil temperature is 20-25℃). If the temperature is too low, the viscosity of the edible oil will be greater and the filling speed will be slower; if the temperature is too high, the plastic bottle will have a bottle suction scene, affecting the product appearance and thus sales. Therefore, controlling the temperature of edible oil is an indispensable part of production. In summer, the oil temperature is relatively high, or in winter, the oil temperature just produced in the refining workshop is relatively high. Immediate filling will affect the product. In the process, chilled water is needed to control the temperature of the edible oil at a constant temperature.

[0003] like Figure 2 As shown, the current method for constant temperature control of edible oil is to use the chilled water produced by the refrigerator 100 to directly enter the heat exchanger 101 to exchange heat with the edible oil. The chilled water after heat exchange enters a water storage tank 102, and then the water in the water storage tank 102 is pumped out by a water pump 103 and enters the refrigerator 100 for refrigeration. This cycle is repeated to achieve the purpose of temperature control. This is a single cycle mode. The selected type of freezer 100 is generally greater than the required cooling heat (the best energy-saving mode is 75% of the operating load), so the freezer 100 will not work all the time. After the freezer 100 quickly reaches the set temperature, it is in standby mode. At this time, the water pump 103 can be stopped, but this method uses the water pump 103 to supply water to the freezer 100 and to the heat exchanger 101 at the same time. After the freezer 100 is in standby mode, the heat exchanger 101 still needs water supply for cooling, so the water pump 103 cannot be stopped. The power of the water pump 103 directly connected to the freezer 100 needs to be matched with the freezer 100, and the power selection is relatively large. If it is always running, the power consumption is relatively large. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an energy-saving edible oil cooling double circulation system.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] An energy-saving edible oil cooling double circulation system comprises a heat exchange module, an oil delivery pipeline, an oil outlet pipeline, a refrigerator, a return water tank, a cold water tank, a first water pump and a second water pump. The heat exchange module is provided with two sets of heat exchange pipelines which are independent of each other and transfer heat to each other. The refrigerator is used to freeze and cool the water passing through the heat exchange module. The oil delivery pipeline and the oil outlet pipeline are connected to the two ends of one set of heat exchange pipelines. The return water tank is provided with a return water inlet and a return water outlet. The cold water tank is provided with a cold water inlet and a cold water outlet. The water outlet, the return water outlet and the cold water inlet are connected at both ends of the freezer, the cold water outlet and the return water inlet are connected at both ends of another set of heat exchange pipes, the first water pump is connected between the return water outlet and the freezer to pump the water in the return water tank from the return water outlet through the freezer and then flow into the cold water tank from the cold water inlet, the second water pump is connected between the cold water outlet and the heat exchange module to pump the water in the cold water tank from the cold water outlet through the heat exchange module and then flow into the return water tank from the return water inlet.

[0007] Preferably, the return water tank is provided with an overflow water port and a water inlet, and the water inlet is connected to an external water source.

[0008] Preferably, the return water tank is provided with an exhaust port.

[0009] Preferably, the heat exchange module includes three heat exchangers connected in parallel.

[0010] Preferably, the heat exchanger is a plate heat exchanger.

[0011] Beneficial effects of the utility model

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] When the utility model is in use, the first water pump draws the water in the return water tank from the return water outlet, and after being frozen and cooled by the refrigerator, the cold water flows into the cold water tank from the cold water inlet for storage. The second water pump draws the cold water in the cold water tank from the cold water outlet, and after exchanging heat with the edible oil through the heat exchange module, the cold water flows into the return water tank from the return water inlet for storage. When the refrigerator reaches the set temperature and is in standby mode, the first water pump can be stopped, and the second water pump continues to transport the cold water stored in the cold water tank to the heat exchange module for heat exchange with the edible oil. The second water pump is only connected to the heat exchange module but not to the refrigerator, so a water pump with smaller power can be selected to achieve energy saving.

The water outlet 62, the return water outlet 52 and the cold water inlet 61 are connected at both ends of the freezer 4, the cold water outlet 62 and the return water inlet 51 are connected at both ends of another group of heat exchange pipelines, the first water pump 7 is connected between the return water outlet 52 and the freezer 4 to pump the water in the return water tank 5 from the return water outlet 52 through the freezer 4 and then flow into the cold water tank 6 from the cold water inlet 61, the second water pump 8 is connected between the cold water outlet 62 and the heat exchange module to pump the water in the cold water tank 6 from the cold water outlet 62 through the heat exchange module and then flow into the return water tank 5 from the return water inlet 51.

[0020] When the utility model is in use, the first water pump 7 pumps the water in the return water tank 5 out from the return water outlet 52, and after being frozen and cooled by the freezer 4, the cold water flows into the cold water tank 6 from the cold water inlet 61 for storage, and the second water pump 8 pumps the cold water in the cold water tank 6 out from the cold water outlet 62, and after heat exchange with edible oil through the heat exchange module, the cold water flows into the return water tank 5 from the return water inlet 51 for storage. When the freezer 4 reaches the set temperature and is in standby mode, the first water pump 7 stops at this time, and the second water pump 8 continues to transport the cold water stored in the cold water tank 6 to the heat exchange module for heat exchange with the edible oil. The second water pump 8 is only connected to the heat exchange module but not to the freezer 4, so a water pump with smaller power can be selected to achieve energy saving.

[0021] Furthermore, when the freezer 4 is in standby mode after reaching the set temperature, the first water pump 7 stops and the second water pump 8 continues to work, and the cold water in the cold water tank 6 is pumped out from the cold water outlet 62. After heat exchange with the edible oil through the heat exchange module, the cold water flows into the return water tank 5 from the return water inlet 51 for storage. Since there is no first water pump 7 to pump water out of the return water tank 5, the water in the return water tank 5 becomes more and more and overflows. In order to prevent the water in the return water tank 5 from overflowing, an overflow water port 53 is provided on the return water tank 5 to directionally discharge the excess water in the return water tank 5. When the freezer 4 and the first water pump 7 start working again, water is replenished in the return water tank 5 through the water inlet 54, and the water inlet 54 is connected to an external water source 55.

[0022] Furthermore, the return water tank 5 is provided with an exhaust port 56 to facilitate exhausting the hot air generated when the water temperature output by the heat exchange module is high.

[0023] Furthermore, the heat exchange module includes three heat exchangers 11 connected in parallel, so that the number of heat exchangers 11 participating in the work can be selected by switching valves on and off according to demand.

[0024] Preferably, the heat exchanger 11 is a plate heat exchanger.
