Apparatus and Method for Chilling or Freezing Objects Utilizing a Rotary Drum Having Prominences Formed on an Inner Surface Thereof

摘要: In an apparatus and method for chilling or freezing objects, interior surface of a rotating drum includes recesses formed between prominences extending inwardly from the surface. One more liquid CO 2 nozzles inject solid towards The injected snow replenishes depth in empty partially and/or provides fresh layer on top objects. Because is made polyethylene replenished recesses, product/drum sticking problem experienced by conventional apparatuses methods reduced avoided. Optionally, into at least one first nozzle deposited objects second so that each opposing object direct contact with .
