METHOD TO DRY PASTE-LIKE MATERIALS IN ROLL-AND-TAPE DRYER WITH VARIATION OF PLATE CONVEYOR MOVEMENT SPEED Russian patent published in 2011 - IPC F26B17/04 F26B25/22 

FIELD: construction.

SUBSTANCE: method to dry paste-like materials in a roll-and-tape dryer includes formation of dried material, its serial movement through drying chambers in process of counterflow-cross-like movement of a drying agent, removal of which is carried out in cyclic mode, which includes saturation of the drying agent and removal of the drying agent, besides, duration of removal and stop is identified depending on the specified moisture content of the drying agent. At the same time, depending on speed of plate conveyor movement, time of dried material stay is identified in n and n+1 chambers of the drying plant, in which the main or surface moisture is removed, and material moisture is assessed online in n and n+1 chambers with multiple sensors along neuron networks, compliance of calculated material moisture values with the rated ranges is verified, depending on which numerical estimates are defined for measures of trust to achieve the required material moisture at the drying plant output, and on the basis of produced values of material moisture in the specified chambers and numerical estimates of trust measures a fuzzy inference is produced, which defines the value to change the plate conveyor movement speed to achieve the required quality of material at the output of the drying plant.

EFFECT: achievement of the required material quality at the drying plant output with optimal efficiency of drying process.
