Bonding mutually easily between the big particle of surface viscosity, after by predrying device processes, thereby its surface moisture content descends, viscosity descends dispersion.Need meet the following conditions to handling the drying of back particle this moment:
1, particle need be detained the regular hour in drying tower, so that particle can be dried fully as required.
2, because this device is used for the processing of reconstituted rice/recovery cereal, because the cereal difference of processing, parameters such as required drying time, dry back water content also are not quite similar, so the holdup time of particle in drying tower must be controllable.
3, owing to the particularity of reconstituted rice/recovery cereal processing, the drying time of particle can not be of a specified duration excessively, causes the particle surface be full of cracks to avoid its internal-external dehydration inequality.
4, because particle surface viscosity is bigger, though through predrying device processes, its surface viscosity has reduced, yet still need avoid intergranular bonding.
