Long time freezing will lead to form block ice in cells. These block ice will damage cells and influence the quality of IQF fruits or vegetables. Instant freezing is an effective way to avoid it. Different with other freezing machines, the air blast from bottom to top, all the surface will contact with cold air evenly, articles are frozen in a short time, generally the freezing duration is 10-15 minutes. Fluidization makes freezing more deeply, quickly and thoroughly.
Our fluidized IQF tunnel freezer for vegetable and fruit correspond to standard of food hygiene. Energy saving and high efficiency. The largest capacity of the freezing machine can reach to 5000kg/h. It is also available to design based on customized requirements.
Runing Principle
• Low temperature - Freon system supply cold energy, the evaporative temperature can be -45℃ or lower. Cryogenic environment is kept in insulation cabinet.
• Two phases freeze - Initial phase generates small ice rapidly and freeze articles surface, the duration is about 5 minutes. Final phase hardens the small ice, The core temperature reaches to -18 degrees Celsius. This duration is about 5-10 minutes.
• Blast freezing - Powerful fans in the bottom of the freezer. Those fans supply enough air volume to form fluidized state.
• Vibratory conveying system rotate and tumble to prevent articles from sticking with each other.
