Method and apparatus for controlling removal of gaseous cryogen from a continuous tunnel type freezer wherein the cryogen and product to be frozen travel in counterflow heat exchange relation to minimize ambient atmosphere moving into the tunnel and out of the exhaust system with the exhausted gaseous cryogen.

Exhaust system for a cryogenic freezer

Method and apparatus for rapidly crust or through freezing a particle by simultaneously moving the particle through a bath of cryogenic liquid and exposing the particle or portions of the particle not submerged in the liquid to a spray of the cryogenic liquid.

Liquid nitrogen immersion/impingement freezing method and apparatus

Method and apparatus for quick freezing particles with surface moisture by immersion in liquid cryogen to produce a frozen crust or layer on the particles followed by agitation in content with the vaporized cryogen to complete freezing and prevent clumping of the particles.

Method and apparatus for individually quick freezing small surface moist

Improving the connective heat transfer of a tunnel type cryogenic freezer by positioning the circulating fan blades upside down and closer to the articles moving through the tunnel.
