The bombay engg works manufactures a range of mixers/granulating drying fluid bed processors. These are designed to meet stringent production and environmental requirements of the pharmaceutical, food, chemical and allied industries. The range of machines offers improved performance, simplified maintenance and utilises modular construction techniques to provide flexibility in installation options. The machines made up off from 304, 316 grade stainless steel and constructed to high gmp principles. Particular attention has been paid to reduce any source of material entrapment by polishing flush all welds to create crevice free profiles both internally and externally. The construction is modular to give greater flexibility, eg, the fan and heater units can be located in a services area - thus simplifying access and maintenance work. The fluid bed dryers utilise the working principle of passing air at a high velocity through the bed of the material to be dried, thus causing it to fluidise. When the correct velocity of air current is maintained, the solid particles are suspended in the intense turbulence and are intermixed and constantly exposed to the drying air current. By application of heat to the air current drying occurs both very rapidly and evenly.
