FIELD: processing industry; construction of heat-and-mass exchange apparatus for separation of multi-component materials into fractions. SUBSTANCE: heat-and-mass exchange apparatus includes monoblock unit made from non-heat-conducting material; it is inclined to level at angle of 1 to 35 deg. Monoblock unit consists of heater 1, sectional unit 2 and dephlegmator 3 with cover 4. Fitted in sectional unit 2 between vertical double partitions 5 and 6 are containers 7 with checker on perforated distributors 8. Each double partition has clearances of upper side of front partition with cover 4, between partitions 5 and 6 and their lower sides with bottom of sectional unit 2 for motion over them in servicing. Each container 7 is made from screened box with checker in it for motion between double partitions in mounting and servicing. Heat-and-mass transfer apparatus may be provided with monoblock articulated on foundation or chassis with hinge on lower end of sectional unit and secured on sectional unit 2; heater is connected with sectional unit by means of flexible hoses; rope-and-block system is also provided for control of angle of inclination of sectional unit on dephlegmator end. EFFECT: rectification, cracking or adsorption of oil, chemical or food- stuff materials. 3 cl, 3 dwg
