Description
Centrifugal and vibrational technological effects are among the main approaches to intensify the process of plant raw materials hydrolysis for pectin extraction. With the impulse intensification of such a process, it is possible not only to increase its efficiency, but also to achieve the compactness of the equipment, reduce the cost of electricity and improve the quality of the product of hydrolysis. The hypothesis is confirmed, according to which the vibro - centrifugal intensification of hydrolysis increases the driving force of the process by not only activating the material flows of raw materials and reagents, but also by reducing the resistance in the tech nological environment.
Graphical and analytical dependencies of the power and energy parameters of the oscillatory system were obtained, which
proved the overcoming of the flow resistance of the liquid medium in the entire speed range of the drive shaft wi
th the potential to intensify the process at a power consumption of 2.0 – 3.0 kW and or by the force of 2.3 – 2.5 kN using the Lagrange and Cauchy methods for composing and solving the equations of motion of the moving components of the tested hydrolyser with vibrating activators, and the methods of mathematical analysis and their processing in the MathCAD. The analysis of the presented parameters of the studied process of mixing the pectin - containing mass in the hydrolyser allowed us to determine the ratio nal mode parameters of processing, which correspond to the angular velocity of the drive shaft rad/s at the power consumption of 500 – 600 watts.
