The technology of producing new types of processed products original DDGS are proposed. The scheme for production powdery product based on rational limits of the physical parameters of the drying process of the thin stillage are developed. This technology allows to get a high quality feed additive in animal rations. Evaporating and drying installations, as well as accessories, working in a closed thermodynamic cycle, results in reducing the consumption of electricity and heat energy as well as steam flow rate. The calculation of the material balance of the process of obtaining a powdered product from the thin stillage are performed. Nutrients and vitamins that saved in the finished product will come in handy to improve the quality of the powder itself. Energy costs were reduced in an average of 15% by using of steam jet installation and recirculation loop for drying agent. Energy consumption of the processes of evaporation and drying the thin stillage are reduced by using of waste heat steam ejector after heating the air before it is fed into the spray dryer. Efficiency of separation whole stillage on a suspended and a liquid fractions and quality of the finished powdery product are increased by using a spray drier with a drying agent with a low temperature in range 75–80°C.

V.S. Ruban, E.G. Stepanova

The questions of preparation of pectine contained raw materials (PCR) to hydrolysis extraction according to the equation of process of hydrolysis of protopectin are considered. Possibility of use of the electroactivated water solutions (EWS) is investigated by preparation of PCR and hydrolysis extraction of the pectic substances (PS) from it. As PCR are used dried apple and citrus marcs. Efficiency of process was estimated on extent of extraction of PS, a constant of speed of hydrolysis extraction and the main quality indicator – jelly-forming ability of the extracted pectin. The comparative analysis of the pectin obtained with use by extragent EWS, hydrochloric and lemon acids is carried out. Besides jelly-forming ability the ash-content and organoleptic properties of the obtained pectins were investigated. It is established that PS greatest an exit and a constant of speed of hydrolysis extraction are reached when using by extragent hydrochloric acid. On 3–4% lower these indicators at the pectins obtained with use of anolytes, prepared on different initial water solutions with various salinity. The lowest an exit of PS and a constant of speed of hydrolysis extraction – when using lemon acid. It is established that EWS application for PS extraction from vegetable raw materials allows to raise an exit and purity of pectins, to simplify process due to preliminary washing of raw materials. Optimum parameters of raw materials preparation processes and PS hydrolysis extraction from it are determined.

Analysis of kinetics of the drying process of potato and vegetables (carrots and beets) superheated steam at atmospheric pressure in a pulsed fluidized bed indicates the presence of the following periods: warm-up period, constant speed and the period of decreasing speed. Were considered the basic laws of heat and mass transfer process of drying food plants (potatoes, carrots and beets) allowing for the change in the kinetic characteristics of each period. In the warm-up period, which is characterized by condensation of vapor on the surface of the product and water absorption, there is an intensive moisture transfer on the surface of the interfacial section “solid – liquid” as a result of thermal diffusion caused by the temperature gradient. Revealed that during the drying intensity oscillate heat exposure is directly proportional to the product of the increment of enthalpy values irrigation steam flow per unit area of the gas distribution grid, the pulsation frequency and inversely proportional to the duty cycle of the steam. Some reduction in the impact velocity superheated steam heat in a period of decreasing drying rate due to the changing nature of the moisture transfer. In this period there was a slight decrease in the beginning of heat transfer coefficient, followed by a sharp decline at the end of the period. The basic laws of heat and mass transfer during drying edible raw superheated steam. Criterial equations obtained to determine the heat transfer coefficient in the periods constant and decreasing the drying rate. The change of temperature and humidity of potatoes and vegetables superheated steam at atmospheric pressure in a pulsed layer.

A.I. Smelyagin, I.V. Yukhnevich

It is shown that for an intensification of chemical and food processes except vibro-mixing devices it is expedient to use reciprocating rotary mixing devices. These devices, thanks to a reciprocating rotary motion of working bodies, have executive mechanisms simple and convenient in operation that does them perspective for application. Use of reciprocating rotary mixing devices restrains because of insufficient development of their executive mechanisms. The conducted researches showed prospects of application of cogwheels as executive mechanisms for reciprocating rotary mixing devices. For obtaining a reciprocating rotary motion it is expedient to use transfers with not round cogwheels. The carried-out analysis of kinematics (the transfer relation) couples of not round cogwheels allowed to formulate a condition under which the unidirectional rotary motion of an entrance link will be transformed to a reciprocating rotary motion of an output link. The original design of the planetary gear mechanism, as with round, and not round cogwheels, for receiving a reciprocating rotary motion is offered. With application of a method of Kutzbach–Smirnov the kinematics of this executive mechanism is investigated, the law of change of the transfer relation is found and is proved that the output link makes reciprocating rotary motions.
