China (Mainland)
Application:
It suits for the big sized foods (such as packed by barrels, boxes and plates), especially fits for the foods which need a long time to be frozen (such as meat, bulk seafood and ice cream)
Major technical parameter of SDD series:
Features:
1. Multi-layer tunnel freezer includes continuous reciprocal series and independent series.
2. Continuous reciprocal series also can be divided into cargo basket model and tray model. The former one has a larger capacity while the latter one works more reliable.
3. The independent series is equal to the addition of several individual tunnel freezers in height.
4. Advanced blowing method and shutter device of wind adjusting ensure the air-flow sensible in cabinet, and make foods be frozen homogeneously.
5.Insulation cabinet: Sandwich structure, composed by foamed PU materials and coated by stainless steel 304 plates on both sides. The density is 42kg/m3. The cabinet door is equipped with electrical heating device (36V) which can prevent the door from freezing. The insulation cabinet contains a special repair door and there is a wide repair path inside the cabinet.
6. Aluminum evaporator: The shell is made of stainless steel. All the evaporators are designed by our engineers. The special different fins distances structure reduces the defrosting intervals, meanwhile, it also can prolong the continuous working time of equipments. Big fins and big upsiding down edges improve the efficiency of heating exchange and make the inner cleaning easy.
7. Special fans for low temperature: Equipped with axial fans whose air box is made of stainless steel and blades are made of aluminum. The shell of motor is hot dip galvanized. Totally enclosed low-temperature moisture-proofed and water-proofed motor (reach IP56) is efficient, energy-saving and reliable.
8. Mesh belt: made of long-range elasticity stainless steel wares. The surface is flat and neat, and it is powerful enough in load bearing. The speed of mesh belt can be adjusted by converter steplessly.
9. Sensible drainage design: The water plate is located at the bottom of cabinet, whose features are welded completely, never penetrate and leak, smooth corner, no sanitation dead angle, slope to waterspout, easy to be cleaned.
10.(Optional)PLC and touch screen: the electrical controlling box is made of stainless steel and is water-proof and dust-proof. The temperature in cabinet is showed by numbers, so it is easy to operate. We adopt SIEMENS PLC. Touch screen can show the operating condition dynamicly. You can set many controlling points by touch screen, for example, the fans, the electrical heating device, ultra-high alarming device and so on. So the operation is more clearly and human.
11.Advanced restriction device of location: it is equipped with special restriction device of loacation on every layer, which ensures the trays work reliable.
