Vibrations in engineering and technology

Polievoda Yurii – candidate of technical sciences, associate professor of the department of technological processes and equipment for processing and food production, Vinnytsia National Agrarian University: Vinnytsia, st. Sonyachna 3, 21008, e-mail: vinyura36@gmail.com.

The considered effective way of processing by-products of biofuel production. The increase in the productivity of the technological line is achieved through the introduction of new vibration equipment for the primary purification of raw glycerin.

This study proposes a new approach to determine the efficient operation of a new machine, which is useful for the purification of glycerol based on the combinatorial process of centrifugation and vibration separation. The mathematical mechanical-rheological evaluations are developed based on the experimental results.

Has been proposed to evaluate the rheological characteristics of raw glycerin purification based on the experimental testing. A compression device has been used to determine the value of the unilateral deformation of this material, which allows simulating a condition of a material at various technological modes of processing. In this study, the changes of material properties under centrifugation and vibration separation processes in a vibrocentric machine have been investigated.

At a choice of optimum technological parameters of processing of food masses by means of vibration methods of rheology are widely applied. In particular, the interaction of the working body of the machine with the treated environment.

In order to find the optimal parameters of the technological regime, the process was considered comprehensively from the standpoint of mechanics and rheology. The methods of mechanics describe the interaction of the working body with the treated environment as a mechanical object; rheology, in turn, allows you to reveal the internal processes in the environment.

The system under study can be attributed to the elastic-viscous medium, which is described by a phenomenological model consisting of interconnected elastic and viscous elements.
