Individual Quick Freezing usually abbreviated IQF Freezing Machine is a freezing method used in food processing industry. Products commonly frozen with IQF Freezing technologies are typically smaller pieces of food products and can range from all types of berries, fruits and vegetables diced or sliced, seafood such as shrimps and small fish, meat, poultry and even pasta, cheese and grains. Products that have been subjected to IQF are referred to as Individually Quick Frozen or IQF'd

One of the main advantages of this method of preparing frozen food is that the freezing process takes only a few minutes. The exact time depends on the type of IQF Freezing and the product. The short freezing prevents formation of large ice crystals in the product’s cells, which destroys the membrane structures at the molecular level. This makes the product keep its shape, colour, smell and taste after defrost, at a far greater extent.

Another significant advantage of IQF Freezing technology is its ability to separate units of the products during freezing, which produces higher quality product compared to block freezing. This advantage is also important for food sustainability, as the consumer can defrost and use the exact needed quantity. There is a range of IQF Freezing technologies, but the main concept is to transport the product into the freezer with the help of a processing line belt or infeed shaker. Inside the freezer, the product travels through the freezing zone and comes out on the other side. Product transportation inside the freezer is by different technologies. Some freezers use transportation belts similar to a conveyor belt. Others use bed plates that hold the product, and an asymmetrical movement makes the plate advance by itself through the freezer.

IQF Freezing Machine :

The dryer vaporizes the moisture in the material by heating to obtain a solid material having a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. In modern enterprises, the use of compressed air is becoming more and more common. Common compressed air dryers mainly include adsorption GF Machine and freeze dry nachine. What is the difference between a Freeze Dry Machine and an adsorption dry machine?

1, the difference in working principle

According to the principle of freezing and dehumidification, the freeze dry machine cools the saturated compressed air from the upstream to a certain dew point temperature by heat exchange with the refrigerant, and condenses a large amount of liquid water, which is separated by the gas-liquid separator and automatically discharged outside the machine to the purpose of water drying. The Adsorption Dry Machine is based on the principle of pressure swing adsorption, and the saturated compressed air from the upstream is contacted with the desiccant under a certain pressure, and most of the water is adsorbed in the desiccant, and the dry air enters the downstream work to achieve the purpose of deep drying.

2, the difference in water removal effect

Because the Freeze Dry Machine is subject to its principle, if the temperature is too low, it will freeze, so its dew point is usually 2~10 °C. While the Adsorption Dry Machine does not have to pass the temperature change, and the desiccant (alumina) can be further dried. Therefore, the dew point of the outlet can usually reach below -20 ° C, which means deep drying can be achieved.

3, the difference in energy loss

For the Freeze Dry Machine , the cooling power is achieved by the compression of the refrigerant, so the power of the power supply will be high. Since the Adsorption Dry Machineonly controls the valve by the electric control box, the electric power is usually only about several tens of watts, that is, there is no power loss.
