IQF fruit blueberry freeze drying machine is the best choice for fast freezing of fruit and vegetable food monomers such as granules, flakes, bars or blocks.
Fruit and vegetable quick-freezing equipment is suitable for a variety of materials: blueberries, strawberries, french fries, corn kernels, carrots, mushrooms and so on.
Freeze drying machine working principle:
Blueberry quick-freezing machine adopts stainless steel mesh belt as conveyor belt. Fruit and vegetable food is blown by the strong cold air flow from the bottom to the top of the mesh belt to form a semi-suspended state. The cold air flow swirls around each food monomer, so that the heat of the food core is quickly dissipated and the cold and heat exchange speed is accelerated. At the same time, a large number of individual foods move forward with the stainless steel mesh belt in a semi-fluid state. The lower part of the mesh belt is designed with an efficient mechanical pulse vibration mechanism, which increases the fluidization effect and greatly improves the unit rate of food.
The quick-freezing device of IQF blueberry machine is divided into: one-stage and two-stage. The one-stage type is the fluidization movement of the material on a mesh belt throughout the entire freezing process, so it is suitable for quick freezing of easily broken food monomers, such as: asparagus, strawberries, and so on. In the two-stage method, fruits and vegetables are divided into two sections during the freezing process. The first section is fast freezing on the surface layer. Under the action of the pulse vibration device, the food particles are not sticky to each other, and then enter the second section for deep freezing. The food particles are completely frozen, and the two sections take different speeds to increase the yield.
