Lateral and Fluidized Bed Dryer

Drying aims to eliminate by vaporization the liquid impregnating a solid. Example applications: beetroot pieces, banana slices, yeast, dog kibbles, corn kernels, puffed rice, frozen peas, etc. Pedagogical Objectives: Study of drying of food or food-compatible products in an educational or research context. Learn about Lateral and Fluidized Bed Dryer exporters for optimal educational outcomes..

Technical Description: A circuit comprising 3 drying modules. Fluidized bed dryer: diameter 200 mm, load 500 g.

Air circuit: HORIZONTAL SWEEP MODULE — 304L stainless steel casing with front-opening door. Interior fitted with 3 stainless steel grid racks on an open structure resting on the balance platform. Balance located outside the casing to avoid high-temperature exposure. Peephole on door for product temperature measurement by pyrometer. Air flow diversion during weighing mode. FLUIDIZED BED MODULE — 304L stainless steel product bowl with interchangeable screen (two screens supplied, mesh size to be specified) and polycarbonate expansion zone for good product movement visibility. Fluidized bed diameter: 200 mm. Sample port nozzle for in-process moisture sampling. Mechanical locking of product bowl. Recovery hatch at the base of the fluidized bed. CONNECTING DUCTS — Food-grade thermolac-coated steel ducts (colour to be selected). Duct sections and drying modules connected by high-temperature clamp joints, easily demountable for cleaning. AIR HEATER — Two 15 kW modules. FAN — Direct-drive centrifugal fan. Flow adjustable by variator.
