Centrifuge equipment continuous filtering centrifuges

Centrifuge Dryers Usually they are batch or continuous filtering centrifuges (Sec. 18, "Liquid-Solid Operations and Equipment ) with hot air being blown over the solids in the discharge section. Manufacturers include Heinkel and Bird-Humboldt.

The basic raw materials required include starting culture E. coli cells), nutrients (glucose and salts), tryptophan, water, ammonia and air. The process equipment includes fermentor, mixing tank, continuous heat sterilizer, centrifugal compressor, air filter and storage tank.

As shown in Fig. 11.1-1, the solids—liquid separation device is the link between the solids formation equipment and the diying operation, Thus, predictable and reliable operation is essential in this stage of the processing sequence. Continuous or baich-automatic centrifuges nad continuous vacuum filters are typically used to recover solid material from continuous crystal I ization operations. Many factors are considered in [ha final selection of the device. In any case, an equipment testing program is always essential to determine the capacity and performance of solids separation equipment. 

The cost of operation of chemical process equipment varies widely. Some equipment requires more skill, operators of better technical training, and more supervision than others (see Table 6-14). Engineering experience must be relied on to furnish most of this information. Available within each company are data on equipment operating labor costs, with typical values of 0.2 man per unit for continuous filters, evaporators, and columns, 0.5 man per unit for centrifuges, dryers, and continuous reactors, and 1.0 man per unit for batch reactors. 

Continuous flow centrifuges or other equipment that may produce aerosols are to be contained in devices that exhaust air through HEPA filters before discharge into the laboratory. 

Wet classification is performed by filtration, settling, centrifugation, Sind hydrocyclones. When operated in conjunction with grinding equipment, the wet classification equipment must operate continuously and give a pumpable fluid. This is often accomplished in practice with hydrocyclones because the other methods are unsuitable (e.g., settlers and centrifuges are used for dilute suspensions, filters and screens produce a nonpumpable cake.)...
