Current technological aspects of lactose crystallization are considered. A promising lactose crystallization method involving simulation seed crystals is reported. Advanced engineering solutions for continuous crystallization using spraying in vacuo and scraped-surface heat exchangers are presented. Key words : lactose, heterogeneous and homogeneous crystallization, simulation seed crystals, continuous crystallization of lactose, scraped-surface plate-type cooling crystallizer, vacuum spray crystallizer. INTRODUCTION Lactose crystallization is among the necessary technological operations in the production of sweetened canned condensed milk. This operation consists of creating appropriate conditions for extensive formation of crystallization centers and for subsequent controllable crystal growth at certain processing parameters and under post-production storage conditions. The lactose crystallization kinetics can be described in terms of a C = f ( t
