ABSTRACT:
Process for quick freezing and conditioning of individual products, and apparatus to practice this process. The process is characterized in that it consists essentially in treating small individual quantities of different products in modular indivdual quick-freeze chambers (1) fed with cryogenic gas and connected each to a quick-freeze tunnel (3) so as to provide in the latter a low temperature, and in treating larger quantities of product pieces in the tunnel (3), provided with a conveyor belt (4) and which is also fed with cryogenic gas, in evacuating the residual warmed gas obtained from the interior of the tunnel (3), in packaging the products leaving the tunnel in insulating packaging disposed in a receiver (6) mounted at the outlet of the tunnel (3), or in filling the packaging with products issuing from a chamber, then in surrounding the assembly of products disposed in the packaging with a cryogenic product, and closing the packaging.
