PROCESS AND APPARATUS FOR FREEZING IN PLATES TO OBTAIN ICE MATRIXES WITH A UNIFORM DISTRIBUTION OF SOLUTES

摘要

This invention is a controlled freezing process and an apparatus that aims to attenuate the effect of cryoconcentration of solutes that occurs during the freezing of aqueous solutions, by means of a freezing method that gives the user an adequate control of the speed and of the direction of the interface between the solid and the liquid phases in order to incorporate the solutes uniformly in the ice matrix. This invention has applications in the pharmaceutical industry, the food industry and also in the industry for development and commercialization of cryogenic technology.
