Abstract
Description
Technical Field
[0001] This application relates to the technical field of carrying items to be cooled through a refrigeration zone using a conveyor device, and more specifically to a quick-freezing machine with a cleaning system. Background Technology
[0002] Utility model patent document CN211953399U describes a quick-freezing machine with a cleaning system. The quick-freezing machine has a heating chamber on one side, and a water outlet solenoid valve at the bottom of the heating chamber. The water outlet solenoid valve is connected to a drain pipe manual valve and a first connecting pipe via a three-way connector. A drain pipe is fixedly installed at the end of the drain pipe manual valve away from the three-way connector. The end of the first connecting pipe away from the three-way connector is fixedly connected to the input end of a water pump. A second connecting pipe is fixedly installed at the output end of the water pump. An output pipe solenoid valve is fixedly installed at the end of the second connecting pipe away from the water pump. An output pipe is fixedly installed at the end of the output pipe solenoid valve away from the second connecting pipe. Several cleaning nozzles are evenly installed at the bottom of the output pipe. When cleaning the quick-freezing machine, the water in the heating chamber is heated, and the water pump is turned on, allowing hot water to be delivered through the first and second connecting pipes to the cleaning nozzles to rinse the inside of the quick-freezing machine.
[0003] After the outlet pipe extends into the blast freezer to complete rinsing and drainage, and the refrigeration system inside the blast freezer is restarted, the water remaining in the drain pipe and cleaning nozzles exposed inside the blast freezes due to the low temperature, causing blockages in the drain pipe and cleaning nozzles. Although a manual drain valve can be opened to drain water from the heating tank and pipes, the drain pipe is horizontally positioned, and the cleaning nozzles are mounted on the drain pipe. Even opening the manual drain valve cannot drain the water remaining in the drain pipe and cleaning nozzles. Restarting the blast freezer will cause the remaining water in the drain pipe and cleaning nozzles to freeze and cause blockages, affecting the operation of the automatic cleaning system. Summary of the Invention

[0022] Reference Figure 1-2 This application proposes an embodiment of a quick-freezing machine with a cleaning system. The quick-freezing machine 10 has a drain outlet at its bottom, and the automatic cleaning system includes:
[0023] Heating box 20 is used to hold and heat cleaning liquid, and the heating box 20 is equipped with an air cap on the top;
[0024] The delivery pipe 30 is connected at one end to the outlet of the heating box 20 via a delivery pump 40, and at the other end to one end of a cleaning branch 50 via a three-way valve. The other end of the cleaning branch 50 extends into the quick-freezing machine 10. A nozzle 60 for spraying cleaning fluid into the quick-freezing machine 10 is installed on the cleaning branch 50. A first valve 70 is provided on the delivery pipe 30, and a second valve 80 is provided on the other port of the three-way valve.
[0025] The air compressor 90 is connected to the second valve 80.
[0026] See attached document Figure 1 As shown, when the automatic cleaning system is working, the heating tank 20 heats the cleaning liquid contained inside it, the first valve 70 is opened, the second valve 80 is closed, the delivery pump 40 is started, and the delivery pump 40 sends the cleaning liquid contained in the heating tank 20 through the delivery pipe 30 and the three-way valve to the cleaning branch 50, and sprays it into the quick-freezing machine 10 through the nozzle 60 on the cleaning branch 50. The wastewater after cleaning the quick-freezing machine 10 is discharged through the drain port, thereby cleaning the inside of the automatic cleaning system.
[0027] After cleaning is completed, the first valve 70 is closed and the second valve 80 is opened. The air compressor 90 is started and compressed air is supplied to the delivery pipe 30 through the second valve 80. The compressed air is delivered to the cleaning branch 50 through the delivery pipe 30, thereby pushing the residual water in the delivery pipe 30 and the cleaning branch 50 to continue to spray out from the nozzle 60. This sprays the residual water in the delivery pipe 30 and the cleaning branch 50 into the quick-freezing machine 10 through the nozzle 60. The air compressor 90 continues to supply compressed air to the delivery pipe 30. The compressed air enters the quick-freezing machine 10 through the nozzle 60. The compressed air helps to push the water accumulated in the quick-freezing machine 10 out of the drain port, thus preventing water accumulation in the quick-freezing machine 10.
[0028] Preferably, the system also includes an air heater 100, with the outlet of the air compressor 90 connected to the inlet of the air heater 100, and the air heater 100 connected to the second valve 80.
[0029] The quick-freezing machine 10 has many internal components. After the automatic cleaning system rinses the quick-freezing machine 10, moisture often remains on the inner wall, evaporator coil, fan, and conveyor belt of the quick-freezing machine 10. Restarting the internal refrigeration system of the quick-freezing machine 10 after rinsing it may cause freezing on the inner wall, evaporator coil, fan, and conveyor belt of the quick-freezing machine 10, affecting the normal operation of the quick-freezing machine 10.
[0030] Therefore, in this embodiment, an air heater 100 is also provided between the second valve 80 and the air compressor 90. After the air compressor 90 generates compressed air, the compressed air is heated by the air heater 100 before being sent into the conveying pipe 30, the cleaning branch 50, the nozzle 60 and the quick-freezing machine 10. The heated air is sent into the quick-freezing machine 10 to blow hot air to dry the inside of the quick-freezing machine 10, thereby increasing the evaporation rate of moisture in the conveying pipe 30, the cleaning branch 50, the nozzle 60 and the quick-freezing machine 10.
[0031] Specifically, a drain valve 110 is provided on the drain outlet.
[0032] When the automatic cleaning system rinses the quick-freezing machine 10, the drain valve 110 is opened; after cleaning is completed, the drain valve 110 is closed, and the compressed air generated by the air compressor 90 is heated by the air heater 100 and then sent into the quick-freezing machine 10, extending the residence time of the heated compressed air in the quick-freezing machine 10, so that the heated air can fully exchange heat with the quick-freezing machine 10 before being discharged, ensuring the heating effect inside the quick-freezing machine 10. The drain valve 110 can be controlled to open and close according to the working process of the cleaning system. For example, when the cleaning system is rinsing the inside of the quick-freezing machine 10, the drain valve 110 is opened. After the cleaning is completed, the first valve 70 is closed and the second valve 80 is opened to discharge the residual water. The drain valve 110 is closed for a period of time to allow hot air to heat the inside of the quick-freezing machine 10. After the residual water is fully heated and steam is generated, the drain valve 110 is opened to discharge the steam and hot air, so as to avoid the compressed gas from generating too much pressure inside the quick-freezing machine 10 and affecting its performance. At this time, the inside of the quick-freezing machine 10 is heated, and the air compressor 90 continues to deliver compressed gas, which continues to evaporate and heat the residual water.
[0033] Preferably, the drain valve 110 is connected to the sewage collection pipe 120.
[0034] After the hot cleaning fluid rinses the inside of the quick-freezing machine 10, depending on the quick-frozen product, the wastewater after rinsing the inside of the quick-freezing machine 10 may carry contaminants such as grease, food residue, and microorganisms. Therefore, the wastewater after rinsing is discharged and collected through the wastewater collection pipe 120 to facilitate the subsequent treatment of the rinsing wastewater.
[0035] Preferably, an exhaust pipe 130 is installed at the top of the sewage collection pipe 120, and an automatic exhaust valve 140 is installed at the upper end of the exhaust pipe 130. After the residual moisture in the conveying pipe 30, cleaning branch 50, nozzle 60, and quick-freezing machine 10 is removed, compressed air will pass through the cleaning branch 50 into the sewage collection pipe 120 and be discharged through the automatic exhaust valve 140. Referring to the attached drawings, the height of the automatic exhaust valve 140 is higher than the height of the bottom of the quick-freezing machine 10.
[0036] In this embodiment, a control box 150 is also included. The first valve 70, the second valve 80, and the drain valve 110 are all solenoid valves. The control box 150 is connected to the delivery pump 40, the first valve 70, the second valve 80, the drain valve 110, the air compressor 90, and the air heater 100, respectively. The control box 150 notifies the delivery pump 40, the first valve 70, the second valve 80, the drain valve 110, the air compressor 90, and the air heater 100 to control their actions, thereby realizing the automatic cleaning of the quick-freezing machine 10.
[0037] Preferably, the cleaning branch 50 includes a collection path 51 and multiple cleaning sub-paths 52. One end of the collection path 51 is connected to the delivery pipe 30 through a three-way valve, and one end of each of the multiple cleaning sub-paths 52 is connected to the collection path 51. The multiple cleaning sub-paths 52 are arranged at intervals along the length of the quick-freezing machine 10 to ensure effective cleaning of the inside of the quick-freezing machine 10.
[0038] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
