SHAFT KILN FOR LOOSE MATERIAL CALCINATION Russian patent published in 2017 - IPC F27B1/14 F27D1/16 

FIELD: food industry.

SUBSTANCE: invention relates to sugar production technology, namely to equipment for obtaining saturation gas used for purifying the raw juice, and is used for obtaining lime in shaft kilns in the industry of construction materials, chemical and metallurgical industries. The shaft kiln for loose material to obtain saturation gas used for purifying the raw juice contains a cylindrical lined shaft, the outer surface of which is coated with fine fiber basalt material made in the form of twisted bundles arranged as extended in height from the box operating in the air supply mode to the charging device.

EFFECT: shaft kiln for the loose material calcination, ensuring the reduction of energy consumption for the heat and mass transfer process of obtaining saturation gas by maintaining the given temperature mode inside the kiln without additional fuel costs for heating lime raw material from the ambient temperature, especially at low and negative values and in case of moistening by precipitation, to the calcination temperature.
