Large-scale Fluidized Bed Dryer with In-bed Heat Exchanger

Working Principle: 　　 Preheated gas (air) is passed into the product layer under controlled velocity after being uniformed by the distributor so as to create a fluidized state. Fluidized bed dryer with in-bed heat exchanger is superior in an advanced drying technique combined with normal fluidized bed drying and indirect conduction type drying. The in-bed heat exchanger enhances heat transfer of solid particles and thermal medium and improves drying efficiency and drying capacity. Characteristics: 1. Efficiency in energy saving is high. Most heat is provided by the in-bed heat exchanger with the efficiency...

Large-scale Vibrofluidized Bed Dryer

Working Principle: Vibrofluidized bed is a new technology developed on the basis of static fluidized bed. Mechanical vibration is added on the fluidized bed. Wet material particles enter the air stream and form a fluidized bed. The material is ejected due to exciting force. Vibrations of an air distributing plate incite the fluidization of material particles and the movement of material in the fluidized bed. The fluidized material contacts the hot air and at the same time carries on heat and mass transfer. The dried product is discharged through the discharge port. Characteristics: 1. Uses the advanced vibr...

GLW Fluidized Bed Dryer

Working Principle: Preheated gas (air) is passed into the product layer under controlled velocity after being uniformed by the distributor so as to create a fluidized state. The raw material is fed into the bed. The dehydration process can take place under very good heat & mass transfer conditions (good uniformity of the material in the bed). The exhaust air is cleaned by cyclone. Characteristics: 1. Simple structure, convenient overhaul. 2. Simple steady operation 3. The air and solid contact evenly with high thermal efficiency. 4. Low expenses of equipment maint...

Large-scale Double Mass Vibrofluidized Bed Dryer

Working Principle: NGLZ large-scale vibrofluidized bed dryer uses double mass resonancetype structure. Inertia exciter and resonance mass make up a resonatingsystem. The ordinary electrical motor drives the gear exciter through gimbals to produce exciting force. The exciting force is enhanced several times by a resonating spring and acts on the mass to fluidize the material. The material is ejected due to the exciting force. At the same time,the hot air is supplied at the bottom of the vibrofluidized bed and penetrates the material layer,so the material particles get in full contact with the hot air jet and an ideal drying effect is achieved. ...

Spray Fluidized Bed Dryer

Working Principle: It has an additional atomizing device based on an ordinary fluidized bed structure. Hot air is supplied to the dryer from the bottom of wind box with an air distributor. Raw material is atomized by a spray nozzle and spread on the fluidized material to be coated and pelleted by different systems. The material after coating and pelleting can be dried and cooled in a fluidized bed. Characteristics: The surface modification of powder consists of coating and agglomerating, these two technologies to get desired granular products, and drying, pelleting and cooling are completed in one equipment...
