Integrated fluid bed dryers for easy removal of moisture
Shachi Engineering provides a wide range of industrial dryers including industrial fluid bed dryers. These dryers are used to reduce moisture from large quantities of bulk materials. Fluid bed dryers are customized to deliver on specific process and production requirements. Shachi can provide fluid bed dryers across varying capacities ranging from small scale pilot plant to a full-scale industrial plant. Fluidized bed dryers are generally used in industries such as food, fertilizers, pharmaceutical industry, and plastic industry among others. Businesses prefer fluid bed dryers due to their high efficiency, relatively low maintenance costs, reduced contact time for drying, and ease of control.
Working principal of fluid bed dryer
Fluidized spray dryer comes with a perforated metal base, through which hot air is introduced to dry the feed on flow. In fluid bed dryers, the material to be dried is held afloat by a layer of air. Air must flow in the right velocity through the bed of solids so that the weight of the particle in a fluidized state is supported. This mechanism results in an intense movement of the particles as bubbles form and collapse within the particles. In this state, solids tend to behave like free-flowing liquids. As there is intimate contact between particles and fluidized gas, high heat and mass transfer rates can be obtained.
Types of fluidized bed dryers
Fluidized bed dryers are broadly classified into batch-type and continuous fluid bed dryers. There can also be static and shaking fluid bed dryers. However, these dryers can be modified and integrated with many other drying mechanisms to obtain desired results.
Batch type dryers
Batch type dryers are suitable for processing granules or crystallized materials Perforated belts are used in batch-type dryers to transport feed material through the dryer. These machines can be modified with multiple belts and work as multiple-pass machines. Extraction in fluidized bed dryers is normally central-induced.
Continuous fluid bed dryers
Continuous fluid bed dryers are better suited for materials with relatively high moisture content. They have multiple zones for heating and cooling of the material. Resident time of the product in any zone is dependent on length o the zone, frequency and amplitude of vibration and the use of dams.
Integrated fluid bed spray dryers
A fluidized dryer is integrated with spray dryers as the combination allows a longer residence time at lower and safer temperatures without the risk of over-drying. Shachi’s integrated fluid spray dryers come with several inherent core strengths that include high yield and energy efficiency and one of the lowest operating costs in the industry.
Integrated fluidized spray dryers are employed for producing large and agglomerated particles. These dryers are customized to deliver on specific process and production requirements. Fluidized spray dryer comes with a perforated metal base, through which hot air is introduced to dry the feed on flow.
