The development of modern equipment and technology leads to healthy competition, which in turn allows you to freely choose a machine or installation for the separation of liquid inhomogeneous systems. Each production when choosing equipment takes into account the relevant factors and its specifics.
Mathematical and statistical planning of a multifactorial experiment was used to refine the glycerin quality indicators and determine their weight.
The article constructs the response surfaces of the optimization criteria, which allow us to clearly illustrate the dependences of the values of the mass fraction of pure glycerin and energy consumption on individual optimization parameters. The research method includes the selection of optimal modes of operation of the vibrocentric machine for purification of liquid glycerol-containing raw materials according to technical and economic criteria for evaluation and determination of quality indicators of purified glycerol with variation of processing time, process temperature, etc. During the study, special attention was paid to the main operating parameters of this vibrating machine, namely: amplitude-frequency, power and energy.
The efficiency of the process of vibration-based purification of crude glycerol was evaluated on such parameters as vibration control, angular rate of flow, rate of temperature. The recommendations of the second basic parameters of the lateral period were determined in accordance with the second set of the second order.
Analyzing the results of studies of vibration-centrifugal separation of liquid inhomogeneous raw materials, it can be argued that the most influential factors in the separation of these products are the rotor speed, vibration shaft speed, oscillation amplitude, power, temperature and processing time.
