Twist Freezer for Fruits & Vegetables

Cost effective solutions, outstanding quality and reliability are common for Fenco food processing machines.


  • TWIST FREEZER is particularly designed in accordance to the customer needs of "taylor made solution".
  • Very high mechanical reliability of spiral belt conveyor.
  • Reduced belt wear and elongation thanks to low tension drive system (the belt is pulled by means of dynamic friction on the total length).
  • Belt system lubrication is free of any possible risk of product contamination.
  • Long work cycles due to "symmetrical" large fins spacing design on the air entrance, and oversizing of evaporator.
  • Possibly to have bi-directional "clockwise, and counter clock wise" air flow in the evaporator "efficiency", having automatically longer running cycle.
  • TWIST FREEZER is designed as "Easy Clean" concept avoiding point of dirtiness accumulation.
  • TWIST FREEZER has as standard ventilation the "VOT" concept "horizontal tangential type" air flow.
  • Low maintenance cost, and low spare parts cost due to the use of high quality commercial components.
  • Belts and drum gear motors positioned outside the insulated cabin, avoiding any risk of contamination due to some oil leakages.
  • Central Drum drive supported by roller bearing.
  • Stainless steel flexible belt or plastic belt for special application such as sticky or tender products with low water content products.
  • Spiral structures made of stainless steel.
  • Low pressure fans to increase air speed and heat exchange.
  • Flat tin evaporators with low air pressure drop.
  • Fully automatic washing system (option) with lose water.
  • C.I.P. "Cleaning in Place" system with the possibility to use basic - acid - detergent and disinfectant solutions (option).
  • PLC and touch screen supervision system (option).
  • Ice Extraction Belt "Patented" (option), positioned just on top of the evaporator, which assure a continuous run minimum 48 hours between each defrosting cycle, with the possibility to work up to 72 - 120 hours in accordance to the type of product and the environmental conditions.

Applied in a freezer is a solution that provides to keep as much as possible the recycled air free from moisture - ice, and from product flying particles during the freezing operations.
Ice is generated due to the water - moisture losses coming from the products (evaporation) and from the incoming air during the product feeding - loading.
Quantity of products flying particles varies in accordance with the type of products, on process.
Usually ice and products flying particles are captured in the inner parts of the freezer, and mainly into the coils - evaporators.
With the increasing of ice accumulation into the coils - evaporators, the efficiency of those units will drop drastically, then usually to maintain the same efficiency - performances a higher power consumption is needed.
As consequences periodically the freezer needs to be stopped for the de-frosting operation, with considerable drop page in the production with a certain increase of the operative costs.
SFA concept and application will improve the following:-

  • - Considerable increase of the freezing cycle and production.
  • - Minimising the number of stoppages and defrosting cycles, with much lower operational costs.
  • - Minimising the energy consumption needed to obtain the final results.
  • - Improvement of the final product quality, while the frozen product is almost free from ice on its surface (this is particularly appreciate for the products which are packed in a transport packages).

SFA is a mesh wire conveyor positioned all around the coil - evaporator, and because of this is acting as continuous air filter.
It runs for the full length of the freezer, with an outside extension to discharge the ice - end product particles out of the freezer chamber.
The mesh is continuously cleaned - blow and dry before coming back into the cabin, it is possible to have also a water cleaning system in case of more demanding cleaning operation (optional).
The air flow pass first through the product and then to the SFA before it reaches the evaporators. The mesh filters will capture the majority of the ice - frost, and product debris. The freezer therefore remains relatively free with much longer freezing efficiency - production. As consequence the coils - evaporator surface will remain more cleaner giving better performance.
With this system the stoppages due to defrosting - cleaning and machine sanitation will be drastically reduced by approx. 50 - 80% , subject to the type of product.


  • Minimum defrost cycle:-    48 hours "guaranteed"
  • Nominal defrost cycle:- up to 72 - 120 hours
  • (subject of product type and environmental conditions).

This is Fenco "patented" solution.
