DEVELOPMENT OF ROTOR-VACUUM FILM EVAPORATOR FOR CONCENTRATING CONIFEROUS EXTRACTS

A new structure of a rotor-vacuum film evaporator used for intensifying the concentration of liquids containing biologically active substances has been developed and investigated. A mathematical model has been constructed; on its basis, an apparatus design algorithm block-diagram has been devised to permit the optimization of the process. Dependences of the main physico-chemical and thermophysical characteristics of coniferous medicinal extract on the temperature and concentration have been established. Based on the carried out investigations and the constructed mathematical model, a prototype of the rotor-vacuum film evaporator has been worked out and produced; it can be used in pharmaceutical, food, microbiologic industries and other branches of biotechnology for concentrating liquids, with biologically active substances maintained in their native state. Dependences of the physical and chemical characteristics of a conifero medicinal extract have been determined; they have been used for analyses optimization of the apparatus operating conditionsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
