COOLING SPEED & QUALITY
The range from 0℃ to -5℃ is called "Maximum Icing Crystal Formation Zone" in food freezing, and the speed to pass through this temperature zone will influence the size and shape of ice crystal formed, then determine the quality of frozen foods.
  • SLOW FREEZING：
    The ice crystal formed in large shape and small quantity among cells, would destroy the food structure, then drip away nutrition and water and lose weight after defrost.
     
  • QUICK FREEZING：
    The crystal formed becomes a large number and minified shape, would not destroy the food structure, reserve the freshness and quality; less weight lost after defrost.
     
  • DOUBLE FREEZING EFFECT： 
    The FRESER CONVEYOR IQF, with its stainless steel conveyor belt, delivers the foodstuffs into a polyurethane well-insulated freezing chamber; with -35℃ cooling air blasts over the top of foods, and direct contact with the stainless steel belt at the botton. The steel belt is sprayed ed with -40℃ cold brine from below and cooled down.Under this double freezing effect, foodstuffs can be deeply frozen in quite a short time with identical surface and core temperature.

    Since the speed of passing through "Maximun Icing Crystal Formation Zone" is much faster than conventional freezers, the ice crystal formed in small shape and large number, will not destroy the food structure, reserve the freshness and quality, thus the color, taste and flavor can be restored after defrost.
FEATURES：
  • Full-Function Control System：
    Equipped with digital display, can be precisely monitoring temperatures of refrigerant and brine, the load conditions of major equipments in the system; also provides setting and control, alarm and protection required.
     
  • Durable Insulated Cabinet：
    Adopt high quality steel plates with formed-in-place polyurethane insulation to make the panels. With the assembly desigh feature, easy to install, reassemble and maintenance, and the flexibility to increase capacity.
     
  • Efficient Air Blast System：
    High quality special fan motors for inside use in freezing chamber, engineering air volume design, number of cooling units and its layout, assuring the most efficient cooling air flow recirculating system for saving energy.
     
  • Speed Adjustable S/S Conveyor：
    The stainless steel belt is in full contact with the products, renders high efficiency of heat transfer; equipped with cleaning device to maintain sanitation of belt surface; the time for food to pass through the freezing chamber can be adjusted by speed adjuster according to different products and its thickness in order to reach complete freezing effect.
     
  • Variety of Application：
    The stainless steel belt can assure the fine freezing treatment with no deformation of products, with or without packing. Therefore, the FRESER IQF can be extensively applied to the freezing process of processed food, marine and agriculture products.
