IF Blancher

The OctoFrost™ IF Blancher achieves the quickest heat transfer by means of a rain shower system. It allows accurate temperature control within 0.2°C to avoid over-blanching the product. The filtered and recirculated water is heated by steam injection and free falls gently over the product.


Every product is surrounded by a static layer of air that insulates it and slows down heat transfer. The OctoFrost™ IF Blancher and Chiller use a rain shower system to break this static layer through impingement technology. This results in the fastest heat transfer through conductivity – the essence of OctoFrost™ Impingement technology.


Due to the OctoFrost™ cross-flow water system, the water flowing through the IF Blancher and Chiller has the exact same temperature in all zones. The user has absolute control over the blanching and chilling temperatures as well as time.


  • Weighing Belt for an even infeed into the blancher
  • Flexibility of different temperature zones to avoid over-blanching
  • Energy Efficient steam injection into the blanching water
  • Cross-flow water circulation
  • Quicker chilling process which improves yield and product quality
  • System temperature in the IF Chiller is below 6°C for reliable food safety
  • Low temperature of chilled products improves IQF Freezer performance and product quality (longer time between defrost, higher capacity, and less lump formation)
  • Significantly faster transfer due to the impingement rain shower system
  • High volume of recirculated water over the product
  • CIP system in place
