Abstract

The comparative analysis of existing methods of dehydration of thermosensitive materials was conducted, the main advantages and disadvantages were highlighted.

The energy-efficient device for concentration (dehydration) of thermolabile materials in anaerobic conditions was proposed.

The required quantity of heat, the amount of heat transfer agent and the minimum surface area of heat-mass exchange for the dehydration process in the rotary film evaporator were calculated.

The experimental study of the dehydration of solutions of methanogen, grown on the molasses and distillery stillage showed the possibility of obtaining the concentrated solutions, and the possibility of their application at startings and failures in the reactor operation. The activity of the obtained concentrates of methanogens is 1-3×107 cells/l.

The possibility of using the rotary film evaporator for concentration of thermosensitive materials in anaerobic conditions was studied. The optimal technological and thermophysical parameters of the concentration (dehydration) process were experimentally determined.
