When the purpose of the invention is to prevent the heater, with the granules, the work is discharged and the rolls are reduced to foaming; when the drainage is silted during their operation due to the temperature difference in the carbonation. 10 as a result of heat losses, the pore size
нагревател меньше, чем на периферииthe heater is smaller than the periphery
