Fluidised freezing tunnels series M




Tunnels series M - capacities from 1700 to  3400 kg/h for green peas or 1200 to 2400 kg/h for strawberries.


Both ammonia NH3 (R717) as well as freon R404A or R507 can be used as refrigerant in freezers series M.


All tunnels of this series can be additionally equipped with UDS (Equipment for continuous frost removal from evaporators) providing longer operation time between defrostings. As standard execution you will find pulsator, which supports fluidisation effect and improves quality of frozen product (IQF) and also external system of washing the first belt.


Washing system of the first belt can be activated by operator at any time. System can operate periodically or in automatic cycle.
