Description

Technical Field

[0001] The utility model relates to the technical field of vacuum frying machines, and more specifically, to an energy-saving cooling device for vacuum frying machines. Background Art

[0002] With the rise of vacuum frying and de-oiling machines, low-temperature fried foods are increasingly recognized by people. They are superior to ordinary fried foods in terms of taste and color. A vacuum frying and de-oiling machine, whose structure includes a frying and de-oiling chamber and an oil storage chamber in a tank body. With the help of an external circulation oil continuous heating and filtering device, the oil in the oil storage chamber is pumped into the frying and de-oiling chamber. After frying for a period of time, the oil on the food is thrown out through a centrifugal de-oiling device. Due to the use of low-temperature vacuum frying, generally around 90°C, the used oil can also be recycled. A large amount of high-temperature gas is generated during the operation of the vacuum fryer, which requires a corresponding cooling device for cooling.

[0003] After searching, the utility model patent with Chinese application number CN201620625255.1 discloses a cooling device for a vacuum fryer, including a vacuum fryer, the vacuum fryer is connected to an air supply pipe, the air supply pipe is connected to a cooling barrel, and the cooling barrel is connected to a refrigeration compressor. The high-temperature gas generated by the frying tank of the utility model is cooled by the refrigeration compressor in the cooling barrel, and the structure is simple, the space occupied is small, the installation and disassembly are convenient, and the cost is saved.

[0004] When cooling is performed, the compressed and cooled air enters the cooling barrel through the compressor outlet pipe, and is spirally arranged in the cooling barrel through the pipe, which is beneficial to cooling the high-temperature gas in the gas pipeline. After the temperature in the cooling barrel rises, the gas in the pipeline enters the compressor through the compressor inlet pipe, and the compressor circulates, which first reduces the temperature inside the cooling barrel and then cools the temperature inside the pipeline. In addition, since the gas has a certain flow rate in the pipeline, it is not convenient to directly cool the heat inside the pipeline, and the cooling effect is poor. The cold temperature inside the cooling barrel is easily dissipated through the cooling barrel, resulting in a waste of cold air, a waste of cold temperature, and an increase in cooling costs.

A first spiral tube 4 is arranged inside the cooling box 3, and the first spiral tube 4 is connected with the vacuum fryer 1 through an air pipe 5. A spiral sleeve 6 is sleeved outside the first spiral tube 4, and both ends of the spiral sleeve 6 are fixedly connected with sealing plates 14, and the two ends of the spiral sleeve 6 are sealed by the sealing plates 14. The bottom of the spiral sleeve 6 is connected with the air inlet end of the compressor 2 through an air outlet pipe 7, and the output end of the compressor 2 is connected with a condenser 8, and the condenser 8 is connected with the upper side of the spiral sleeve 6 through an air inlet pipe 9. A second spiral tube 10 is arranged inside the cooling box 3, and the second spiral tube 10 is connected with the first spiral tube 4 through a connecting pipe 11. One end of the second spiral tube 10 away from the connecting pipe 11 is connected with a vacuum pump air inlet pipe 18, and the vacuum pump air inlet pipe 18 extends to the outside of the cooling box 3, and the air inlet pipe 9 is connected with an external vacuum pump.

[0031] In this embodiment, the vacuum fryer 1 is evacuated by an external vacuum pump, and at the same time, the compressor 2 works. The gas compressed by the compressor 2 is dissipated through the condenser 8, and the low-temperature liquid refrigerant is transported to the interior of the spiral sleeve 6. The low-temperature liquid refrigerant is directly coated on the outside of the first spiral tube 4, and can directly cool the interior of the first spiral tube 4, thereby improving the cooling effect. Since the liquid refrigerant has a certain flow rate inside the spiral sleeve 6, the liquid refrigerant outside the first spiral tube 4 can quickly absorb the heat inside the first spiral tube 4. At the same time, the low temperature of the low-temperature liquid refrigerant located outside is transferred to the interior of the cooling box 3, so that the interior of the cooling box 3 is in a low-temperature state. The cooled gas inside the first spiral tube 4 is transported to the interior of the second spiral tube 10 through the connecting pipe 11, and the interior of the second spiral tube 10 is secondary cooled by the cold air inside the cooling box 3, thereby improving its cooling effect.

[0032] See also Figure 2 and Figure 5 The cooling box 3 is provided with a vacuum chamber 12 inside, and a vacuum tube 19 connected to the vacuum chamber 12 is provided at the bottom of the rear end of the cooling box 3. A valve 20 is installed on the vacuum tube 19. A plurality of support blocks 13 are fixedly connected inside the vacuum chamber 12, and the support is provided by the support blocks 13. The top of the cooling box 3 is connected with a box cover 16 through screws 15, and the box opening of the cooling box 3 is sealed by the box cover 16. The bottom end of the box cover 16 is fixedly connected with a heat preservation sealing pad 17 to ensure the heat preservation and sealing of the connection between the box cover 16 and the cooling box 3.

[0033] In this embodiment, the vacuum tube 19 is connected to an external vacuum pump and the valve 20 is opened to evacuate the interior of the vacuum chamber 12 through the vacuum pump, so that the interior of the vacuum chamber 12 is in a vacuum state. After the vacuum is evacuated, the valve 20 is closed. At the same time, the box cover 16 and the thermal insulation sealing pad 17 can achieve the effect of thermal insulation and sealing of the cooling box 3, thereby avoiding the loss of cold temperature inside the cooling box 3 and the loss of energy. Compared with the prior art, it has a certain energy-saving effect while ensuring the same cooling effect.

[0034] In summary, when the overall equipment is in use:

[0035] The vacuum pump inlet pipe 18 works with the vacuum pump connected to the outside to evacuate the interior of the vacuum fryer 1. The high-temperature gas inside the vacuum fryer 1 enters the interior of the first spiral tube 4 through the gas delivery pipe 5. At the same time, the refrigerant is compressed by the compressor 2 and transported to the interior of the condenser 8. The high-temperature liquid refrigerant is dissipated by the condenser 8 to generate low-temperature liquid refrigerant. The low-temperature liquid refrigerant enters the interior of the spiral sleeve 6 through the air inlet pipe 9. The interior of the spiral sleeve 6 forms a low-temperature environment, which cools the interior of the first spiral tube 4 and the interior of the cooling box 3.
