Subjects of the research: process of multifunctional method of the apricot fruit drying. Purpose of work: The purpose of work consists in working out combined drying of apricot fruits with usage of new physical ways of influence and creation highly effective energy saving installations and devices. Methods of research: Researches on disscrtational work arc spent with application of traditional methods of measurement of temperature, humidity and the expense of heat-carriers, structure and weights of raw materials and finished goods. Processing of results of experiments on the combined drying is based on a method of planning of experiments Received results and their novelty. In work on the basis of the system analysis the expediency of processing of fruits is proved by the combined method, laws of mass-heat exchange characteristics of apricot fruits (hygroscopic, distribution of a time and energy communication of a moisture with a material) after their processing by IR-pulse influence and in sugar syrup arc revealed. The methodology of carrying out of process of the combined drying is developed. Analytical-experimental receptions receive mathematical model of investigated processes. It is experimentally studied kinetics of process of osmotic drying and adsorption in a sugar syrup. Rational values of the factors influencing process of osmotic drying and adsorption in a sugar syrup, and also IR - convective drying of fruits of an apricot arc revealed. Practical value. The scientific motivation of the choice of the apricot IR-convective drying technological mode with preprocessing the last in sugar syrup and development of the methods of the engineering calculation of the multifunction method of the drying. Increase of product output is more than 1,4 times. Degree of embed and economic effectivity: Expected economic benefit of introduction of the developed technology at processing of apricot fruits for a season will make 40,6 million sum, (taking into account drying of other fruits to 90 ton dried fruits for a year or with productivity of a technological line of dried fruits of 1000 kg/days) makes over 183 million sum in a year. Field of application: Tin industry.
