Description / remarks: 

Used Spiral Freezer: brand Thriphase type T303. This in mint condition spiral freezer has a freezing capacity of max. 2.340 kg/h based on potato products with an infeed temperature of +80°C. Production capacity depends on the product data. Specifications of this used spiral freezer:

  • Completely made of stainless steel
  • Infeed / outfeed: North/South
  • Infeed/outfeed height: 90 mm / 4165 mm
  • Type of belt: new stainless steel Ashworth 1” pitch Omnigrid fine mesh belt with B26-12-17 mesh overlay and stainless steel flites fitted to both edges

  • Effective belt length: 260 m
  • Maximum product height: 45 mm
  • Number of tiers: 28
  • Minimum/maximum belt speed: 7- 15 m/min.
  • Drum drive by chain
  • Stainless steel evaporator with 4 pieces high pressure ventilators of each 17kW with a total air flow of 180.000 m³/h and split up in 3 blocks of each 242kW at an evaporating temperature of -40°C, hot gas defrost
  • Stainless steel switchboard cabinet with Siemens PLC S7/Simatic touchscreen with graphical display
  • Defrost system by running fans after production (max.18 hours depending on the amount of snow on the evaporator)
  • Belt wash installation
  • The spiral freezer is designed in such a way that the freeze down process can be continued during a very long period of production by placing an extra evaporator block of 242kW (sequence defrost). During a defrost cycle with hot gas one cooler will be disconnected by means of an automatic sliding door, which guarantees the air flow by the other two remaining coolers.

This spiral freezer will be delivered without panels, floor and housing (if desired this can be provided by our company).

Freezer will be completely checked by Comron International after sale in case of mechanical/electrical defects. The gearboxes will be supplied with new oil, the evaporator blocks will be tested on nitrogen pressure and the freezer will be delivered with a 3 months guarantee on the main components.
