Self-Stacking Spiral Freezer

The product is sent into the vertical cold air flow area of the spiral freezer through the stacked spiral conveyor belt.
The cold air is exchanged via evaporator to freeze product quickly and evenly,resulting in product core temperature reaching requested degree finally.
The complete process ensures each product frozen individually and continuous mass production as well.The product passes through the ice crystallized zone at the maximum speed to reduce freezing time,leading to achieve higher quality product and minimal dehydration.

Working Principle

Spiral freezer 's working principle is described as follows:The product is sent into the vertical cold air flow area of the spiral freezer through the stacked spiral conveyor belt.The cold air is exchanged via evaporator to freeze product quickly and evenly,resulting in product core temperature reaching requested degree finally.The complete process ensures each product frozen individually and continuous mass production as well.The product passes through the ice crystallized zone at the maximum speed to reduce freezing time,leading to achieve higher quality product and minimal dehydration.

Product Application

High efficiency self-stacking spiral freezer is applicable for all kinds of common foods,such as poultry,segmented meat,prepared meal,ready-to-eat products,pasta products,baker foods,aquatic products,etc. And it is especially suitable for those products with high temperature infeed,such as fried foods,bakery foods,cooked foods and other products with high quality requirements.

Product Features

1.Unique stacking conveyor belt system

product blown off;Smaller belt driving force,requires small power motor and saves the energy;Mesh belt tension device adjusts tension automatically to avoid belt jamming and flipping.

2.Efficient vertical airflow

Centrifugal fan,bigger air pressure and volume,requires less fans;Fan placed on the “dry side” of evaporator,optimizes the air flow speed through evaporator;Cold airflow is vertically sent into the freezing area by the centrifugal fan, short quick freezing time,low dry loss and high quality.

3. Adjustable air pressure balance device

Improves airflow balance,increases cold capacity utilization rate,and eliminates internal and external heat exchange.

4. Automatic defrosting device

Improves the heat exchange efficiency of the evaporator and extends the continuous working time.

5. The automatic cleaning system

The automatic cleaning system stable and consistent cleaning effect,no bacterial growth residue,and more hygienic.

6. Modular fully welded stainless steel floor board design

Prevents water accumulation,avoids cold runaway and cold bridge phenomenon,and reduces the basic load.
