Description

Technical Field

[0001] This utility model belongs to the field of cooling spray technology, specifically relating to a cooling water circulation mechanism for a cooling spray system. Background Technology

[0002] Cooling spraying of fruits and vegetables is a pre-cooling and preservation technology. It mainly involves spraying cold water onto the surface of freshly picked fruits and vegetables, using the contact between the cold water and the fruits and vegetables to exchange heat, thereby achieving the purpose of cooling.

[0003] Existing equipment uses water from a tank to spray water through spray pipes for cooling fruits and vegetables. Because the water is added to the tank all at once and flows through a long pipeline, the water in the tank gradually exchanges heat with the external environment during the cooling process. As the spraying time increases, the water temperature rises, and the cooling effect on the fruits and vegetables diminishes, failing to achieve the goal of pre-cooling and preserving freshness. Furthermore, the existing equipment requires frequent refills of the tank to ensure continuous operation, resulting in very low production efficiency and high labor costs. Utility Model Content

[0004] The purpose of this invention is to provide a cooling water circulation mechanism for a cooling spray system, which solves the problem that the spray water temperature of existing equipment is uncontrollable and the cooling effect on fruits and vegetables is poor.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A cooling water circulation mechanism for a cooling spray system includes a water tank, an equipment compartment next to the water tank, a water pump and a heat exchanger installed at the bottom of the equipment compartment, an outlet pipe connected to the water tank, the other end of the outlet pipe connected to the water pump, a heat exchanger inlet pipe connected to the water pump, the heat exchanger inlet pipe connected to the heat exchanger, a circulation pipe connected to the heat exchanger, the other end of the circulation pipe connected to the water tank, an inlet pipe connected to the circulation pipe, and solenoid valves installed on both the circulation pipe and the inlet pipe. The heat exchanger is also connected to a refrigerant input pipe and a refrigerant output pipe, which are connected to a chiller assembly. The water tank is also connected to a water supply pipe. A temperature sensor is installed inside the water tank, and a control panel is also provided. The temperature sensor, chiller assembly, solenoid valves, and control panel are electrically connected.

[0007] Furthermore, a filter is installed at the end of the water outlet pipe near the water pump.

[0008] Furthermore, the heat exchanger is a plate heat exchanger.

[0009] Furthermore, the refrigeration unit includes a compressor, a condenser, and a heat exchange plate.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] 1. This utility model includes a water tank, an equipment compartment next to the water tank, a water pump and a heat exchanger installed at the bottom of the equipment compartment, an outlet pipe connected to the water tank, the other end of the outlet pipe connected to the water pump, a heat exchanger inlet pipe connected to the water pump, the heat exchanger inlet pipe connected to the heat exchanger, a circulation pipe connected to the heat exchanger, the other end of the circulation pipe connected to the water tank, an inlet pipe connected to the circulation pipe, a solenoid valve installed on both the circulation pipe and the inlet pipe, a refrigerant input pipe and a refrigerant output pipe connected to the heat exchanger, the refrigerant input pipe and the refrigerant output pipe connected to a chiller assembly, a water supply pipe connected to the water tank, a temperature sensor installed inside the water tank, and a control panel. The temperature sensor, chiller assembly, solenoid valve, and control panel are electrically connected.

[0012] This setup introduces cooling water from the supply pipe into the water tank until the tank reaches its maximum water level, at which point the water intake stops. During the water intake process, when the cooling water level in the tank reaches the minimum water level, the cooling water circulation mode is activated. The water pump starts, and the cooling water in the tank is discharged from the outlet pipe and enters the heat exchanger through the heat exchanger inlet pipe. Simultaneously, the chiller components start, causing the refrigerant and cooling water to exchange heat within the heat exchanger, lowering the cooling water temperature. The cooling water then flows out of the heat exchanger and returns to the water tank through the circulation pipe. After multiple cycles, the cooling water temperature gradually decreases. When the temperature sensor detects that the cooling water temperature has reached the preset value, the cooling water spray can then begin. In this mode, the control panel closes the solenoid valve of the circulation pipe and opens the solenoid valve of the inlet pipe. Cooling water flows out of the heat exchanger and into the inlet pipe, then flows into the subsequent spraying mechanism and returns to the water tank. The water pump continuously runs, drawing cooling water from the tank and sending it into the heat exchanger for heat exchange to ensure that the spray water remains at the preset temperature. This cycle ensures that the cooling water is always kept at the preset temperature during spraying, achieving precise control of the cooling water temperature, ensuring the cooling effect on fruits and vegetables, and the cooling water can be recycled, effectively improving the operating efficiency of the spraying system, ensuring production efficiency, and significantly reducing labor costs.

[0013] 2. In this invention, a filter is installed at the end of the outlet pipe near the water pump. This feature filters impurities in the cooling water, ensuring stable and efficient operation of the cooling water circulation mechanism during cooling water circulation. Attached Figure Description

[0025] A cooling water circulation mechanism for a cooling spray system includes a water tank, an equipment compartment next to the water tank, a water pump and a heat exchanger installed at the bottom of the equipment compartment, an outlet pipe connected to the water tank, the other end of the outlet pipe connected to the water pump, a heat exchanger inlet pipe connected to the water pump, the heat exchanger inlet pipe connected to the heat exchanger, a circulation pipe connected to the heat exchanger, the other end of the circulation pipe connected to the water tank, an inlet pipe connected to the circulation pipe, and solenoid valves installed on both the circulation pipe and the inlet pipe.

[0029] In the implementation of this invention, cooling water is introduced into the water tank through the water supply pipe until the water level reaches the maximum level, at which point the water supply stops.

The water pump starts, and the cooling water in the tank is discharged from the outlet pipe and enters the heat exchanger through the heat exchanger inlet pipe. Simultaneously, the chiller components start, causing the refrigerant and cooling water to exchange heat in the heat exchanger, reducing the cooling water temperature. The cooling water then flows out of the heat exchanger and returns to the water tank through the circulation pipe. After multiple cycles, the cooling water temperature gradually decreases.

In water spray mode, the control panel closes the solenoid valve of the circulation pipe and opens the solenoid valve of the inlet pipe. Cooling water flows out of the heat exchanger and into the inlet pipe, then flows into the subsequent spray mechanism and returns to the water tank. The water pump continuously runs, drawing cooling water from the tank and sending it into the heat exchanger for heat exchange to ensure that the spray water is maintained at the preset temperature. This cycle ensures that the cooling water is always kept at the preset temperature during spraying, achieving precise control of the cooling water temperature, ensuring the cooling effect on fruits and vegetables. Furthermore, the cooling water can be recycled, effectively improving the operating efficiency of the spray system, ensuring production efficiency, and significantly reducing labor costs.
