Abstract: FIELD: machine building. 
     SUBSTANCE: in compliance with first version, granular material drier comprises great number of heat transfer plates spaced apart to allow passage of dried particles. Every heat conducting plate has inlet and outlet openings for passage of heating fluid flow through the plate. System of flowing fluid medium feed allows forcing blowing fluid between plates, for example, air, gas or water steam, across direction of dried material flow. System of flowing fluid medium feed forms the passage for said medium isolated from heating fluid medium flow through plates. In compliance with second version, granular material drier comprises great number of heat transfer plates spaced apart to allow passage of dried particles. Every heat conducting plate has inlet and outlet openings for passage of heating fluid flow through the plate. It comprises also the system of flowing fluid medium feed allows forcing blowing fluid between plates, for example, air, gas or water steam, across direction of dried material flow. Said system air permeable inlet tube running across direction of dried material flow through heat exchange plates to feed blowing fluid medium into drier, and, at least, one air permeable outlet tube running across dried material flow through heat transfer plates to discharge fluid medium from drier. Note here that flow of blowing fluid medium passes through heat transfer plates and is isolated form heating fluid medium flow transfer plates. In compliance with third version, volatile substance evaporator comprises set of het transfer plates spaced apart to allow passage of material flow and is provided with inlet and outlet openings for passage of heating fluid flow through the plate. It comprises also the system of flowing fluid medium feed allows forcing blowing fluid between plates, for example, air, gas or water steam, across direction of dried material flow. Said system comprises air permeable inlet tube running across direction of dried material flow through heat exchange plates and inlet and outlet boxes with heat transfer plates arranged there between. Note here that flow of blowing fluid medium passes through heat transfer plates and is isolated form heating fluid medium flow transfer plates. In compliance with fourth version, volatile substance evaporator comprises set of het transfer plates spaced apart to allow passage of material flow and is provided with inlet and outlet openings for passage of heating fluid flow through the plate. It comprises also the system of flowing fluid medium feed allows forcing blowing fluid between plates, for example, air, gas or water steam, across direction of dried material flow. Said system comprises air permeable inlet tube running across direction of dried material flow through heat exchange plates and inlet and outlet boxes with heat transfer plates arranged there between. In compliance with fifth version, volatile substance evaporator comprises set of het transfer plates spaced apart to allow passage of material flow and is provided with inlet and outlet openings for passage of heating fluid flow through the plate. It comprises also the system of flowing fluid medium feed allows forcing blowing fluid between plates, for example, air, gas or water steam, across direction of dried material flow. Said system comprises air permeable inlet tube running across direction of dried material flow through heat exchange plates and inlet and outlet boxes with heat transfer plates arranged there between. In compliance with sixth version, method of drying corpuscular material comprises introducing material into flow channels to ensure transfer of material in constricted flow by heat transfer plates and their spacing apart, driving the material in constricted flow by gravity in flow channels formed by heat transfer plates, driving heating fluid medium in heat transfer plates for direct and indirect heating of material flowing in flow channels and simultaneous feed of blowing fluid medium from inlet box into outlet box through material subjected to indirect heating across material feed direction and discharging it outside of outlet air box for removal of moisture formed in indirect heating of material. Note here that heating fluid medium flow through heat transfer plates is isolated form blowing fluid medium flow. In compliance with sixth version, method of removing volatile material comprises introducing material into flow channels to ensure transfer of material in constricted flow by heat transfer plates and their spacing apart, driving the material in constricted flow by gravity in flow channels formed by heat transfer plates, driving heating fluid medium in heat transfer plates for direct and indirect heating of material flowing in flow channels and simultaneous feed of blowing fluid medium from inlet box into outlet box through material subjected to indirect heating across material feed direction and discharging it outside of outlet air box for removal of volatile substances formed in indirect heating of material. Note here that heating fluid medium flow through heat transfer plates is isolated form blowing fluid medium flow. 
     EFFECT: higher efficiency.
