METHOD OF DRYING BAST RAW MATERIALS Russian patent published in 2014 - IPC F26B3/00 F26B3/08 

FIELD: heating, drying.

SUBSTANCE: invention relates to the field of drying, namely, to methods of drying stem bast-fibre materials, and enables to improve the efficiency of their drying before mechanical treatment on scutching-and-breaking machine and to reduce energy consumption of drying equipment. The method of drying bast raw materials comprises its preparation, transportation with simultaneous blowing with hot air in the form of a flow of a layer limited in width and directed simultaneously from above and below the middle zone and along the stems. According to the invention the fed flow of heated air flows downwards and upwards through the stem layer due to the change in the trajectory of its motion on the predetermined law by means of mounting on the upper and lower surfaces bounding the air stream of inclined deflectors on the specific scheme.

EFFECT: intensifying the process of drying flax stock through the rational use of coolant.
