1. Product description for aquatic products quick-freezing machine:
Ultra low temperature liquid quick-freezing device made by our company is based on the design and manufacture of the cascade type low temperature refrigeration unit of our company, combined with the characteristics of food freezing process. This kind of equipment is widely used to quick-freeze aquatic products, such as tuna, lobster, large yellow croaker, etc. And it also widely used to quick-freeze health-care food, for example tricholoma matsutake.
2. Working principle
The working principle of ultra low temperature liquid quick-freezing device is put the food (which need to be packaged well first) directly into the pre-frozen low temperature liquid (usually adopt edible alcohol) and then quick-freeze together.
The more detailed operation step:
1.) To make the temperature of freezing-liquid (which is in the low temperature heat-insulation slot) drop to 35 degrees below zero to 80 degrees below zero (the temperature can be adjusted according to various kinds of foods). And then put the fresh foods (which need to be packaged well first) quickly into the low temperature heat-insulation slot (filled with pre-frozen low temperature freezing-liquid)
2.) To make the foods quick-frozen within 2 to 30 minutes, in order to avoid ice-crystals being formed inside the foods and keep the cell membrane of foods from being damaged. At the same time keep the nutrient composition of foods from losing after thawing and keep the original flavor, taste and nutritional value of foods. The taste of food may be even better than fresh food after treating by this way.
3. Components of the equipment system
1.) Refrigeration main-machine:
Adopt cascade type ultra-low temperature refrigeration unit made by our company, the temperature range of outputting liquid is 35 degrees below zero to 80 degrees below zero, the temperature range can be adjusted according to various kinds of foods. The main parts of the equipment adopt international famous spare parts. Ensure the equipment runs steady and efficient. The power of the equipment can be adjusted automatically.
2.) Low temperature liquid freezing-slot: Made of quality SUS304 food grade stainless steel and PU heat-insulation material. Cold-proof bridge is to be designed according to actually request of users.
3.) Shelf for putting products: Made of quality SUS304 food grade stainless steel. Adopt block-based design with fully consideration about liquid circulation channel.
4.) Auxiliary Equipments: Including low temperature liquid circulation pump, liquid storage barrel, cooling towers and so on.
5.) Control System: Adopt industrial grade PLC automatic electrical control system
4. Temperature Range and Freezing time
Temperature range: Liquid temperature 35 degrees below zero to 80 degrees below zero
Freezing time: 10 minutes～40 minutes (the temperature and freezing time can be adjusted according to various of foods)
5. Freezing capacity: 100～2000Kg/H
6. Advantage as shown (compare with the traditional quick-freezing method)
1. Short freezing time, high efficiency, large product yield per unit time, suitable for food processing.
2. Long preservation time, ensure good quality, Keep food in good condition.
3. Low power consumption, little loss of refrigeration capacity, low operation cost, environment-protective and security.
4. Less investment, cost saving more than 30％ compare with the traditional quick-freezing equipment.
5. Safety and sanitation, quick-freezing in relatively low temperature, the bacteria can be killed largely and stopped reproducing.
7. Field of application
Widely applied to food processing and other industrials, such as Tuna quick-frozen, lobster quick-frozen, large yellow croaker quick-frozen, tricholoma matsutake quick-frozen, etc.
