FIELD: fat-and-oil industry. SUBSTANCE: vacuum drying apparatus has pipeline 8, cyclones 9,10, condensing unit and separation unit arranged on portion of pipeline 8 between cyclones and condensing unit. Separation unit has hose-type filters 16 operating in parallel and equipped with vessel 25 for discharge of condensate, discharge branch pipes 29, locking fittings 19,20 and pressure equalizing system. Discharge branch pipes 29 are communicated with steam pipeline 15. Condensing unit has two successively arranged shell-and-tube heat-exchangers 11,12 and steam ejector arranged between heat-exchangers. Apparatus may be used in soap production enterprises for cooling and molding of soap bars in continuous vacuum installations. Construction of apparatus provides for reduced volume of sewage water and maximum catching of soap dust on recovered filtering surfaces and, as a result, reduced involving of soap dust into sewage water. EFFECT: increased efficiency and improved ecology control. 2 dwg
