Self-Stacking Spiral Freezer

Description

DSA self-stacking spiral freezer is a kind of spiral freeze without traditional rail support, the equipment is supported by side plates installed on both sides of the conveyor belt. The lower layer provides support to the upper layer without needs for orbit. Entering from the bottom, the conveyor belt rotates a circle to rise with a thread pitch; at the same time, the second layer belt enters to support the former layer. Accumulations of layer by layer form an overall barrel shape, the conveyor comes out from the highest layer finally. The cold air enter from the upper layer and are restricted in the circular passage enclosed by plates that are installed on both side of conveyor, freezing materials by bellowing layers.

Self-contained freezing zone, with benchmark hygiene (100% air flow), high efficiency, lower consumptions, reliable and less maintenance realized comes from high quality of Aerospace technology; continuous producing creates by comprehensive cleaning system-lower consumption of water, energy and chemicals. So it is more suitable for meat balls, fish balls, sausage, Spring rolls, chicken wings, legs, etc.

Spiral series of quick-freezing device is suitable for the following product:

1.     Prepared food: Dumplings, rice dumpling, steamed stuffed bun, spring roll, meat ball, fried product, ice cream and small package food.

2.     Aquatic products: Fish, shrimp, crab and scallop, etc.

3.     Meat: Kebab and dressed meat, etc.

4.     Baked food：Bread, etc.; Fermentation of various pastries.

Main Characteristics

◆Compact design and less occupied area

◆Unique ventilation, superior quality and high production efficiency

◆Efficient usage on energy and low basic energy-consumption

◆Reasonable design and more reliable operation

◆Thoroughly sanitary freezing environment. According to HACCP sanitary safety concept, the inner is designed for simple cleaning and maintenance, fully conforming to food sanitary requirements. The internal body and mesh belt are made of stainless steel SUS304.

◆With hydrophilic film, the fins of heat exchanger can be avoided from harmful powder of alumina.

◆All roller wheel, turn hub, and guideway are made of sanitary ultra-high molecular weight polyethylene.
