[0002] Diglyceride oil is a healthy edible oil with a high diglyceride content and a low triglyceride content. In the production process of diglyceride oil, a specific refrigeration cycle system is required to transfer heat from a low-temperature environment to a high-temperature environment in order to lower the temperature of diglyceride oil and its related substances. Box-type water-cooled refrigerant is a commonly used refrigeration equipment in the production of diglyceride oil. A water-cooled refrigeration machine is a device that uses water as a cooling medium and achieves refrigeration function through a refrigeration cycle system. It is often used in air conditioning systems in industrial production, commercial places, and some large buildings to provide the required low-temperature environment for specific spaces or equipment.

[0033] Working principle: In the preparation of diglyceride oil, the preparation equipment can be connected to the inlet pipe and outlet pipe on the evaporator 21 through the connecting pipe. After the inlet pipe transports the high temperature oil into the evaporator 21, it can exchange heat with the liquid refrigerant. After the temperature of the high temperature oil is reduced, it can be discharged through the outlet pipe, thus realizing the cooling function of diglyceride oil.

[0034] After the liquid refrigerant absorbs heat from the oil, it vaporizes into low-temperature, low-pressure steam. The low-pressure steam is then drawn into the compressor 22 and compressed into high-temperature, high-pressure steam before being discharged into the heat exchange tube 24 inside the condenser 23. At this time, the water pump 32 is started to draw cooling water from the water tank 31. The water is then transported through the delivery pipe 33 and sprayed out through the nozzle 34. The sprayed cooling water can exchange heat with the high-temperature, high-pressure steam in the heat exchange tube 24. The high-temperature, high-pressure steam can then condense into a high-pressure liquid. The liquid is then guided by the guide pipe 25 and throttled into the expansion valve 26 to become low-temperature, low-pressure refrigerant. It then re-enters the evaporator 21 for heat exchange.

[0035] When the high-temperature and high-pressure steam in the heat exchange tube 24 is exchanging heat in the condenser 23, the fan 36 can be started. The fan 36 can drive the cooling airflow to be sprayed into the condenser 23 from the exhaust pipe 37. The cooling airflow can be combined with the cooling water to exchange heat with the heat exchange tube 24, which improves the heat exchange effect. The airflow after heat exchange can be discharged through the exhaust port 38, and the water flow after heat exchange can be returned to the water tank 31 through the return port for circulation. At the same time, the cooling water can be cooled by the cooling airflow during the fall, which reduces the temperature after heat exchange.

[0036] The drive assembly 47 can drive the rotating rod 45 to rotate, and the rotating rod 45 can drive the turntable 46 to rotate. When the turntable 46 rotates, it can drive the guide block 49 to slide along the guide groove 48. At this time, the spiral plate 43 can slide up and down along the outside of the heat exchange tube 24 under the guidance of the slide groove 41, so as to remove the impurities generated by heat exchange on the outside of the heat exchange tube 24 and prevent it from affecting the heat exchange effect of the heat exchange tube 24.

[0037] When water flows and exchanges heat in the water tank 31, evaporation will occur. When the water level in the water tank 31 drops, the float ball 52 can follow the liquid level down. When the float ball 52 moves the electric contact A53 down and contacts the electric contact B54, the indicator light 55 can be automatically activated to remind you to add cooling water to the water tank 31 in a timely manner.
