Spiral freezer

With the rapid development of food industry and the continuous innovation of food machinery, DLD and SLD series of screw quick freezing devices, a new type of quick freezing device with compact structure and small floor area, which is efficient and energy-saving, have become the choice of large and medium-sized quick freezing food enterprises.

The stainless steel material conveying net belt of DLD and SLD series spiral quick freezing device makes spiral rotation in the freezing room, so as to realize the rapid freezing of materials. The air distribution mode of top blowing and side blowing is adopted respectively, and the freezing time can be selected from 20 to 90 minutes. It is suitable for quick freezing of conditioning food, small package food, cut meat, ice cream, etc. it can also be used for seafood, fruits and vegetables which are not suitable for fluidization and quick freezing.

>>Features of DLD series double helix quick freezing device

◆ compact structure and small floor area: due to the multi-layer spiral structure, the floor area of the freezer is 1 / 3 to 1 / 2 smaller than that of other freezers with the same output.

◆ reasonable design, safe and reliable operation: after years of continuous practical experience and learning from foreign advanced technology, the structural design of the freezer is reasonable, protected by both mechanical and electrical, and reliable operation.

◆ convenient and flexible use: DLD and SLD series quick freezers can be imported and exported in various directions, especially suitable for matching with different food production lines to realize assembly line production.

◆ simple operation, easy maintenance and cleaning: no special technology is required for operation, and you can go to work after simple training. The evaporator is made of aluminum alloy, with large fins that are easy to clean, so as to reduce the residual food and prevent the spread of bacteria; the feeding section is equipped with a strong cleaning device, which can blow the net belt dry at any time to ensure the health of the conveyor net belt; the internal space is large and the number of vulnerable parts is small.

◆ wide range of frozen products: noodles, vegetable rolls, spring rolls, vegetables, fruits, meat, fried products and other small package foods.

◆ stainless steel structure: made of SUS304 stainless steel material, frozen products can be directly placed on the mesh belt to freeze, and the extremely smooth mesh makes the frozen products almost leave no mark; the chain pieces on both sides of the mesh belt are provided with retaining edges, so the frozen products or plates are not easy to slide off the mesh belt.

◆ unique air duct design: the baffle around the spiral tower and evaporator is designed as a symmetrical and smooth circular air duct, which can enhance the heat exchange effect of frozen products and make the inlet and outlet not run cold, and the operator can also enter the warehouse at any time to check the operation.

◆ double sided stainless steel heat insulation storehouse: the heat insulation storehouse adopts double-sided stainless steel polyurethane storehouse plate, the storehouse door is double-layer sealing strip and equipped with heater to effectively prevent freezing.

◆ reliable transmission control: screw drive introduces advanced technology from the United States, frequency conversion control is adopted for mesh belt operation, and the speed can be stepless and adjustable. Stainless steel electric control box, digital display of temperature in the warehouse, reliable operation of the whole equipment.

◆ the large water tank at the bottom of the warehouse is not leaking, and the drainage is convenient: the whole bottom of the warehouse is made of 3 mm SUS304 stainless steel plate, which is impermeable, easy to clean and fast to drain.
