Dryer selection
Selection
1 material original shape particles, powder, particles, sludge, crystals, liquids, pastes, suspensions, solutions, continuous flakes, slabs, irregular materials (small or large), viscous or blocky.
2 Average production continuous operation of feed amount or finished product, batch operation feed amount or finished product and its adjustment range.
3 finished particle state average particle size, particle size distribution, particle density, bulk density, rehydration, and the like.
4 Material inlet and outlet moisture content dry basis, wet basis.
5 material properties Chemical, biochemical, microbial activity, heat sensitivity (melting point, glass transition temperature), moisture isotherm (equilibrium moisture content).
6 drying time drying curve, the impact of operating parameters.
7 heater form contact method (direct, indirect).
8 fuel selection steam, coal, electricity, oil, gas.
9 drying auxiliary equipment fan, dry dust collector, wet dust collector, feeder, discharger, finished product cooling and conveying device.
10 Special requirements constitute materials, corrosive, toxic, non-aqueous solution, flammable and explosive limits, ignition point, color, structure, fragrance requirements.
10 Drying system The area of drying equipment and ancillary equipment. Equipment installation and commissioning process and general requirements
