INDIVIDUAL QUICK-FREEZING OF MOIST ARTICLES USING DEEP FLUIDIZED BED AND INPUT CONDITIONER

摘要

Abstract of the DisclosureAn I.Q.F. system for deep freezing of food articles and the likeemploying a deep bed fluidization second stage freezer and an article condit-ioning first or input stage wherein the initially moist unrefrigerated articlesmassed in a relatively thin deposit are subjected to through-flow of subfreezinggas, preferably under fluidization conditions, for a predetermined period whichremoves substantially all of the sensible heat above freezing without removingthe latent heat from the articles, whereupon, articles thus in condition com-patible for deep bed fluidization freezing in the second stage are deliveredfrom the first to the second stage.
