The product to be cooked is placed on a flexible belt, either orderly or randomly, where the product remains motionless. The belt runs a spiral-shaped path where the product is subjected to a suitable flow of hot air. Cooking can be made in a:
- humid environment obtained with direct steam injection;
- dry environment obtained with dry hot air make-up.
Both cooking types feature automatic humidity control.
A special horizontal air circulation system ensures a high degree of temperature uniformity across the belt.
The belt drive is based on a simple and reliable central drum system and requires low tensioning for correct operation. The dwell time/speed of the belt is regulated with frequency variators.
The whole system is enclosed within an insulated cabin.
Each standard MECAIR MA-C system can be individually configured to match customer needs and specifications.
