The fluidized bed freezer machine for quick freezing all kinds of fruit & vegetable and some of the seafood
Working principle:
Adopts the two stage belting structure
First, quick-cooling stage
Second, deep-freezing stage
Independently speed control system, and the speed of the two mesh belts can be changed infinitely
1. Quick-cooling stage: the food particles are to be quick cooled after entering into the blast room
The surface of the particles would frozen and reach the temperature of 0°C
Meanwhile, with the help of the striking chain, the particles would neither stick together nor sticker on the stainless steel mesh belt
2.Deep-freezing stage: food is to be moved on a stainless steel mesh belt, the foodstuff layer loosens with the increasing of the airflow
Some of the foodstuff particles become floating(this is the reason why this equipment is not applicable to big bulk foodstuff) when the air pressure reaches a certain scale, O que traz o espaço entre as partículas de alimentos, é assim que o leito fluidizado passa a ser
porque estão soprando com ar forte de todas
, as partículas flutuantes congeladas de maneira rápida e individualmente
