Fluidized bed freezer can quickly freeze a variety of fruits, vegetables and some seafood
Working guidelines:
Double-section structure can be adopted according to customer requirements
First, the rapid cooling phase
The second is the deep freeze stage
Independent speed control system, the speed of the two mesh belts can be infinitely changed
1.Fast cooling stage: food particles should be cooled quickly after entering the spray chamber
The particle surface will freeze and reach a temperature of 0 ° C
At the same time, under the action of the vibration device, the particles will neither stick together nor stick to the stainless steel mesh belt
2. Deep freezing stage: the food moves on the stainless steel mesh belt, and the food layer becomes loose as the air flow increases
When the air pressure reaches a certain level, some food particles float (this is why this device is not suitable for large pieces of food), which creates voids between the food particles, which is how the fluidized bed is generated.
Floating particles freeze quickly and individually because they blow strong cold air from all directions
