Dryers vacuum rotary

Dryers. Drying, another type of evaporation technique, is suited for waste streams of very high soHds content. Several common types of dryers are vacuum rotary dryers, dmm dryers, tray and compartment dryers, and pneumatic conveying dryers. 

Design Methods for Batch Vacuum Rotary Dryers The rate of heat transfer from the heating medium through the diyer wall to the sohds can be expressed by... 

Performance and Cost Data for Batch Vacuum Rotary Dryers Typical performance data for vacuum rotaiy diyers are given in Table 12-26. Size and cost data for rotaiy agitator units are given in Table 12-27. Data for double-cone units are in Table 12-28. 

TABLE 12-26 Performance Data of Vacuum Rotary Dryers ... 

Use alternate drying method (ex. vacuum drying instead of atmospheric drying vacuum tray dryer, freeze drying, cryogenic CO2 drying, instead of vacuum rotary dryer) where material is subdivided in multiple locations... 

Vacuum rotary dryers plastics, organic polymers, nylon chips, chemicals of all kinds, plastic fillers, plasticizers, organic thickeners, cellulose acetate, starch, and sulfur flakes... 

Vacuum Rotary Dryers. Material is subjected to agitation within a stationary, horizontal shell tinder vacuum. The agitation may be heated to increase drying effectiveness. 

A typical vacuum rotary dryer is illustrated in Fig. 12-74 and a double-cone vacuum dryer in Fig. 12-75.

Type of equipment A continuous vacuum rotary dryer is recommended for case of solvent recovery, rapid evaporation, reduced drying time, and a minimum of loss and injury to the BHC product.
