Summary: Based on the analysis, it has been established that the existing glycerin purification technology is characterized by low productivity and high energy intensity of the process. To intensify this process, a vibrocentric machine for cleaning glycerin was developed, which combines the implementation of centrifugal filtration and vibration deposition of raw materials. As a result of experimental research the effective working modes of this machine are substantiated. In particular, the angular velocity of the driving shaft is 110-120 rad·s-1, the angular speed of the rotor is 120 rad·s-1, the amplitude of the vibration of the container is 4-4,5 mm. According to these parameters, the energy consumption is 1.4 kWh. It is proved that glycerin purification is rationally carried out at a temperature of 60-80 °C and the duration of vibrocentric influence is 300-420 s. The before mentioned parameters allow to obtain a product with a mass fraction of pure glycerol 88,5-89,5%. Provided that the process of initial purification of glycerin is increased 4 times to 90-94 kg·h-1.
