SHAFT MODULAR GRAIN DRYER OF LOUVERED TYPE Russian patent published in 2023 - IPC F26B17/12 

FIELD: drying equipment.

SUBSTANCE: to be used in agriculture and other grain dryers with a gravitational moving layer, for example, mine, louvered, column, etc. Shaft modular louver-type grain dryer, consisting of heated air chambers, humid air chambers, drying and cooling vertical chambers installed on the support frame from modules installed one above the other to form a shaft, each module contains several narrow shafts with top-down several rows of louvers separated from each other and from the walls of the module by inlet and outlet channels. The inlet and outlet channels of each module are separated by partitions from the inlet and outlet channels of the module adjacent to it and are arranged in a checkerboard pattern relative to the module connection boundary, so that the inlet channels of one module pass through the dividing wall into the outlet channels of the module adjacent to it, and the outlet channels of the module, respectively, through the dividing wall pass into the inlet channels of the adjacent module, while the plugs installed on the side of the drying agent inlet and on the side of the removal of the drying agent mixture and moisture from the inter-shaft space and separating the drying-cooling zone from the heating zone and the low pressure zone also arranged in a checkerboard pattern in accordance with the location of the inlet and outlet channels of each module.

EFFECT: due to the alternation of inlet and outlet channels along the width and height of the shaft, the grain dryer ensures uniform heating and drying of grain, high quality of the finished product.
