Impingement tunnel freezer Product details:

1. Design process structure parameters based on the characteristics of frozen products. The evaporator design adopts a super large effective surface area, a large spacing aluminum alloy finned tube group, and a variable spacing design to reduce the temperature difference between the evaporator and the warehouse. The design selection is calculated based on the evaporation temperature of -45 degrees Celsius. Adequate evaporation area, high heat transfer efficiency, fully considering the influence of incoming and outgoing temperatures, designed to delay frosting and extend the working time of the quick freezing machine.

2. The evaporator is equipped with a stainless steel SUS304 air duct bracket and stainless steel fan blades, which are high-efficiency, low-noise, waterproof, moisture-proof, and low-temperature resistant centrifugal fans.

3. The quick freezing machine is equipped with multiple high-pressure air ducts that blow air onto the upper and lower surfaces of the product through specially customized nozzles. This blowing method allows for sufficient evaporation area to better dissipate heat and achieve rapid freezing of the product. Adopting a unique jet blowing design to improve the quick freezing efficiency of cold air on frozen products. The frozen product is winded up and down, making it freeze faster and of uniform quality. Simultaneously design and install low-temperature resistant soft air curtains at the import and export ports. The internal air guide adjustment device can adjust the wind direction at any time to control the symmetry of the cold air and prevent it from overflowing. The fan is equipped with an air guide device on the side of the wall panel perpendicular to the air outlet; The adjustable windbreak insulation device controls the feeding height and avoids the loss of cooling capacity.

4. Adopting an external centralized water valve to control uniform water flushing frost, prevent bacterial growth, maintain cleanliness and hygiene, and meet food hygiene requirements. The indoor evaporator for quick freezing adopts multi-point water spraying to evenly flush frost, and is equipped with a welded stainless steel water pan as a whole; The bottom plate is inclined to prevent water accumulation from turning into ice, and a stainless steel large water tray is also installed on the bottom plate; The warehouse is equipped with electrically heated maintenance doors, and all corners of the quick freezing machine are easy to clean and maintain; Except for the slow operation of the mesh belt, all other transmission devices are located inside the insulation cover, which is easy to disassemble and assemble; Install emergency stop safety buttons and safety warning signs.
