Fluid bed dryer from chitra machineries is used for generating hot air stream at the base of the product container filled with the material. The unit comes with a blower that creates induced draught and fresh air is sucked. The electrical heaters or steam or thermic fluid heaters in the unit heats fresh air and hot air stream expands the material bed at certain velocity & rating turbulance. This process known as fluidisation generates full agitation of solid particles and since hot air surrounds each particle it results in high and uniform heat transfer. This fluid bed dryer helps in fast drying of product without appreciable heat loss and the integrated filter bags helps in preventing particles to escape from the dryer. Fluid bed dryer offers advantages like less floor space occupancy; easy operation; dries material in reduced time compared to tray dryer; distributes uniform temperature through out the product; transfers high heat rate; better production rates with reduced drying time; effective for heat sensitive products; and continuous product movement during drying minimize lump formation, case hardening, etc. This fluid bed dryer is constructed with characteristics like electrically / steam & thermic fluid heated general structure; mild steel & coloured standard model; made out of s.S.304 quality material & polished to the matt finished gmp model; s.S.304 / s.S. 316 quality material product container and retarding chamber contact parts; non-flameproof blower motor [flameproof motor option] suitable to dry wet material; 10 / 30 / 60 / 120 / 150 / 200 / 250 kgs capacity; and steam heating / electrical heating & thermal heating facility. Some of the other salient features of these fluid bed dryers include atmospheric inlet air filtered by non-woven filter cloth; pre /micro v & hepa filters at an extra cost prevent fine dust to pass through the products; digital temperature indicator cum controller for inlet air & digital temperature indicator for outlet air for electrically heated model; digital temperature indicator for inlet & outlet air in steam / thermic fluid heated model [temperature controlling valves on request]; manually operated air dampers control inlet and outlet air flow; adequate capacity explosion safety flap at the rear of dryer and an earthing point to prevent static charge in the machine; and ss304 made contact parts of retarding chamber & product container polished to mirror finished and other parts are made out of ss 304 and polished to the matt finished in gmp model & made out of m.S. & coloured in standard model. The fluid bed dryer find applications for drying granular, crystalline, coarse or similar material in pharmaceuticals, fine chemicals, dyes, food and allied products.
