VACUUM-SUBLIMATION DEVICE FOR APPLICATION OF THIN LAYER OF LIQUID PRODUCT ON MOVABLE SURFACE Russian patent published in 1998 - IPC

FIELD: vacuum-sublimation devices. SUBSTANCE: device includes evaporation chamber provided with liquid product supply branch pipe and distributing device connected with sublimation chamber; one generating surface of evaporation chamber is movable surface. Distributing device is made in form of hollow rod located in parallel with movable surface and perpendicular to direction of motion of surface. Rod has longitudinal slit where porous material is secured; porous material is in contact with movable surface. Evaporation and sublimation chambers are connected by means of slit-like hole formed by movable surface during contact with face of evaporation chamber at point where layer of product escapes from evaporation chamber. Width of hole exceeds length of rod of distributing device. EFFECT: smooth distribution of product to be dried over movable surface. 2 dwg
