A machine for washing, drying and sterilizing textiles in a special purpose facility consists of a housing (13) (as an option, made of a composite material with a wall thickness of 2 mm, providing strength during operation under vibration conditions) inside which an electric motor (6) and a vacuum pump (10). Electric motor (6) (as an option, brand DC31-00002 (Electric motor [Electronic resource] https://radugard.ru/elektricheskij-dvigate\l-dlva-stiralnoy-mashine-DC31-00002) [4], through a belt drive (14) is connected to the drum (7) through the clutch (23) and provides its reverse rotation at various speeds.The drum (7) is rigidly and movably fixed inside the tank (3).The control unit (13) is rigidly fixed on the outer upper side of the housing (13 1), which has a program for various types of textiles and the degree of their contamination.It controls all the technological processes of washing, drying and sterilizing textiles.Tubular electric heater (5) (as an option, brand DC47-00006X ([Electronic resource] ( https://zipm.ru/goods/815870-nagrevatelniy-element-ten-dliy-stiralnoe-mashine-164940242965321568) [5], is rigidly fixed in the lower part of the tank (3), connected via a bus (22) to the power source. Vacuum pump (10) (as an option, brand DC31-00180A) (Vacuum pump [Electronic resource] https://radugard.ru/vacuum-nasos-dlva-stiralnoe-mashine-maxx-m50) [6],

fixed in the lower part of the body (13), connected through a vacuum air duct (15) with a tank (3) and a receiver (11) filled with water used for rinsing textiles. The receiver (11) is connected through the pipeline (18) to the outlet pressure reducing valve (22) and the sewer pipe (19). Ultraviolet lamp (9) (as an option, brand AquaPro UV-S-L (Ultraviolet lamp [Electronic resource] https://radugard.ru/ULTRA-FIOLET-LAMPA) [7], hermetically fixed in the rear wall of the tank (3), connected via bus with control unit (1).

A machine for washing, drying and sterilizing textiles at a special purpose facility operates as follows. Textiles are loaded into the drum (7). Depending on the type and degree of soiling, a washing program is selected. The water entering the tank (3) soaks the textiles. During the rotation of the drum (7), due to the centripetal force, the textiles actively collide with the inner ribs of the drum (7), as a result, dirt is knocked out of the fibers of the textiles. The duration, temperature mode of washing textiles depends on the selected washing program when starting the machine. Rinsing of textiles is carried out in the drum (7) with a rotation speed of 50 - 70 rpm, for 5-7 minutes. Rinsing removes detergent residues from textiles. The extraction of textiles is carried out in the drum (7). With the beginning of the spinning of textiles, the control unit (1) sends a command to the vacuum pump (10), which creates a vacuum in the tank (3) P=289 Pa, which allows you to reduce the boiling point of water to 75°C. Drying of textiles is carried out due to the synergy of the effects of the centripetal force of rotation of the drum (7) and the vacuum in the tank (3) (Amosov V.I. Vacuum drying of linen. Physical processes. - 2016. - No. 4. - P. 55-59. Lavrentieva L.V., Masterova Ya.V., Sosnin E.A. UV inactivation of microorganisms: a comparative analysis of methods // Bulletin of the Tomsk State University, Ser. "Biological Sciences", Appendix, 2003, No. 8, p.108- 113) [8, 9], which ensures the evaporation of water molecules from the fabric fibers in the process of its boiling (t _bale = 75°C) at a pressure inside the drum Р=289 Pa. The tubular electric heater (5) provides an increase in the temperature inside the tank up to 75°C. The increase in pressure in the tank (3) is controlled through the pressure sensor of the vacuum pump (20), the evacuated moist air from the drum (7) is fed through the vacuum air duct (15) to the condenser coil (21) of the receiver (11). Receiver (11) filled with water (t=15°С) for 1/3 of the volume provides steam condensation (t _bp =75°С) in the condenser coil (21) coming from the tank (3). During the injection of moist air in the receiver (11), an increase in the level of air pressure and water level is carried out. Removal of water and moist air from the receiver (11) is carried out into the sewer pipe (19) of the special purpose facility through the outlet valve of reducing pressure (24), to atmospheric pressure, through the pipeline (18).

Sterilization of textile products is carried out at the stages of their extraction and drying, due to the radiation of electromagnetic waves with an ultraviolet lamp, which have a bactericidal effect (λ = 210 nm), which ensures its sterilization from microorganisms, viruses and insects, from linen lice. Sterilization of textiles by ultraviolet radiation is carried out in the process of spinning τ=15 minutes, as well as in the process of drying textiles τ=15 minutes.

Experimental studies were verified on the basis of LLC Proektintertekhnika and allowed to obtain the following results: the use of ultraviolet radiation ensured a decrease in the development of microorganisms and viruses by up to 15-30% (Fig. 3).

Thus, the proposed machine for washing, drying and sterilizing textiles at a special purpose facility is new and provides new useful properties that make it possible to increase the efficiency of sanitizing textiles during sterilization during the technological cycle of processing textiles.
