ULTRA SCRAPED SURFACE CHILLER – FRIGOUNIVERSAL

Can be used for wine, grape juice and distillates.

Refrigeration of a liquid is achieved by operating, with an intermediate refrigerant fuido, a cycle involving the following steps:

  • Evaporation
  • Compression
  • Condensation
    Expansion

Freon or ammonia are used as refrigerants.

The output of a refrigeration system varies depending on a number of factors such as inlet and outlet temperature of the liquid to be refrigerated, temperature and flow rate of the air or condensing water.

Scraped surface evaporators (FRIGOUNIVERSAL)
Scraped surface evaporators consisting of:

  • One or more stainless steel evaporators where the liquid, with continuous passage, transfers heat directly to the refrigerant;
  • Hermetic, semi-hermetic or open type compressor;
  • Condenser designed for cooling with water or air;
  • Control and safety valves and instrumentation, electrical cabinet.

Each tubular element has the surface in contact with the liquid to be cooled continuously scraped by rotating vanes; on the other surface, evaporation of the refrigerant takes place.
The liquid to be cooled flows continuously within the chambers bounded by the tubular elements and two end caps, one of which supports the geared motor for rotation.
Each module is thermally insulated by a layer of polyurethane.
As a result of the scraped surface, a high heat exchange efficiency and uniform refrigeration is achieved even with very viscous liquids.

Dry expansion evaporators
Freon is normally used as the refrigerant.

Flood type evaporators
Ammonia is normally used as the refrigerant.
