Abstract

Abstract

The laboratory equipments are important in elaboration of technologies in freeze

drying, for research of the product quality, amelioration, moreover determination of

transport properties. Our department has a laboratory vacuum freeze drying

equipment. We can register all the data during the procedure. It's important to analyze

this freeze drying procedure, because this is elementary for system designing. we have

constructed the necessary measuring instruments, their arrangement. The

automatitation of this process isn't a simple problem. The principal measured

characteristics are mass of dried product, temperature of dried product layer,

temperature of the heater, vacuum, freezing temperature. We can measure the dried

product's weight by a load cell, with the necessary accuracy.
