<p>#CMT# #/CMT# The drying process for crystalline carbonic acids involves mechanical drying in a first dryer (1) and feeding by a screw conveyor (2) to a fluidized bed produced by a fan (5) in a second dryer (3), then to a heat exchanger (4), drying it at a temperature not exceeding 100[deg] C, preferably not exceeding 90[deg] C and best not exceeding 80[deg] C, producing a product in which the moisture content is less than 1200 ppm (parts per million), preferably less than 700 ppm and best less than 350 ppm. #CMT#USE : #/CMT# For crystalline carbonic acids. #CMT#ADVANTAGE : #/CMT# Easier to transport and store hot acids. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the layout for a form of the process in which the circuit is open on the gas side. 1, 3 : Dryers 2 : Screw conveyor 4 : Heat exchanger 5 : Fan.</p> |
