Core structure composition:

Feeding and conveying system: The material is placed on a variable speed stainless steel mesh belt and enters the blanching box in sequence under the action of the conveyor belt. There are two types of conveying methods: mesh belt conveying and chain plate conveying, and the overall material is made of SUS304 stainless steel. The running speed of the conveyor belt adopts variable frequency speed regulation to ensure that the material can be blanched in the box for a controllable time. The equipment can achieve automatic transmission of both incoming and outgoing materials.

Blanching and cooling treatment system: The equipment is divided into a blanching section and a cooling section. The blanching section completely immerses the material in high-temperature water (commonly 95-100 ℃), and the automatic temperature control system maintains even water temperature. After blanching, the material enters the cooling section through a conveyor belt and is quickly cooled to 2-7 ℃ using room temperature cold water or ice water. The cooling machine adopts an air jet rolling structure, which cools quickly and evenly.

Discharge and water circulation system: The material is automatically sent out by the conveyor belt after being blanched and cooled. The water cycle circulates from the discharge end to the feed end, making the temperature more balanced. Install a filtration system in front of the circulating water pump to prevent impurities from being pumped into the pump. The equipment is equipped with an automatic feeding and discharging system, which can smoothly connect upstream and downstream production lines.

Simplify the operational process

Before starting up, check whether there are any debris in the equipment and slot, and confirm that all components are intact. Connect the power supply, start the conveyor belt no-load test machine, and observe whether it runs smoothly. Set the blanching temperature (95-100 ℃) and conveying speed, evenly feed the material into the inlet, and automatically discharge it after blanching and cooling. Clean the equipment promptly after processing is completed.
