Walk-in Freezer for Food Quick-Freezing (RXLK15)

Walk-in freezer for food quick-freezing (5 degrees Celsius to 85 degrees below zero)
The so-called quick freezing refers to a quick frozen method to ensure the food pass through the Maximun ice-crystal forming zone quickly when the average temperature reaches to 18 degrees below zero. Various changes for food will happen during the freezing process, such as physical changes (volume, heat conductivity, specific heat, dry consumption changes, etc), chemical changes (protein denaturation, color changes, etc), cell tissue changes, biological and microbiological changes, etc.
The characteristic of the quick-frozen food is to maintain the maximum original nutritional value and flavor of foods. In other words, it is necessary to ensure various changes above reach to the maximum reversibility during the freezing process.

The advantages of quick frozen food are as follows:
1. Avoid forming ice crystals among the cells.
2. Reduce the moisture precipitates inside the cells, less loss of juice when the food is being thawed.
3. Obviously shorten the time for the concentrated solute, food organization, colloid and various nutrient components inside the cell tissue to touch each other, the concentrated perniciousness decreased to the lowest degree.
4. To make the food temperature drop quickly below the microbial growth and activity temperature to resist the microbial growth and biochemical reaction advantageously.
It is a short time for food to stay inside the freezer, so it is beneficial to improve the usage rate and continuous productivity of the equipment.
5. Most foods begin to freeze when the temperature drops to 1 degree below zero, most ice-crystal will be formed when the temperature drops between 1 degree below zero to 5 degrees below zero. The stage is called the maximum ice-crystal forming stage. Quick freezing can shorten the freezing time of this stage and remove this part of heat capacity at the quickest speed. It has very important meaning to improve the quality of the frozen food.
