Immersions Freezers are a unique freezer for specialty applications in the food and pharmaceutical industries. Products are dropped into the liquid from the top where they either float or drop to the conveyor submerged in nitrogen. The belt speed determines the total immersion time. Products must generally be sturdy as the mechanical dropping process combined with the submersion and immediate cooling may affect some sensative products.

  • Freezes surface, reduces clumping.
  • Compact size, saves space.
  • Reduce shrink substantially
  • Retain color, moisture, texture and taste.
  • Eliminate drying out of product
  • Perfect for shrimp, mussels, soft fruits and vegetables.  Also freezes chicken tenders plus various meat products, seafood and prepared foods.
  • Excellent pre-freezer for subsequent mechanical refrigeration systems.
  • Easy operation; simple controls
