Kaychenov Improving the system of absorption unit refrigeration The problems of improving the absorption stove cooling system for high quality liquid smoke producing have been discussed in the paper. There is absorption stove construction presented which includes absorber, heat exchanger, low-temperature chamber, ultrasound radiator, and water spray generator. The data on the color depending of the experimental liquid smoke on main factors influencing the process – the coolant temperature and amount of fuel burned – have been presented. The specific surface of the fuel mass fraction of water in the fuel has been determined according to standard procedures. Transparency, color and intensity of staining smoke fluid have been determined organoleptically. The liquid smoke according to the requirements of the current normative documents on safety performance indicators has been tested by standard methods: determination of benzo(a)pyrene, phenol compounds and heavy metals. The equation for estimation the complex quality criterion of experimental liquid smoke on the basis of its chemical composition has been presented. The main factors influencing the complex quality criteria of experimental liquid smoke have been given there. They include the sound pressure level, amount of wood raw material required for pyrolysis, heat exchanging surface, refrigerant temperature, and ultrasound water spray generator efficiency. After processing the experimental data the regression equation of producing liquid smoke by absorption has been received. With the help of the mathematical modeling for absorption process of smoke components by fine-dispersed spray the rational parameters of liquid smoke processing have been founded. The project of technological instructions for the liquid smoke production by using the wood smoke and acoustically generated aerosol has been designed. The project of technical requirement "Liquid smoke Antonio Silver" has been designed as well; it has been tested at producing the commercial batch of dried hydrobionts (snakes). Key words: cooling system, absorption stove, liquid smoke, ultrasound, water spray, heat exchanger.
