sugar granule high efficient fluid bed dryer for food,chemical, medicine, drink powder or granule batch by batch drying
The basic concept of the high efficient fluidized bed dryer
1.1 The basic principle of boiling dryer
Definition of boiling dryer: Boiling dryer is also known as fluidized drying, which refers to the process of drying medium to dry solid particles in a fluidized state.
The principle of boiling dryer: refers to the drying medium to dry the solid particles in the fluidized state. The basis of the material drying process is the boiling of the powder. At the same time, under the action of exhausting, the fine powder in the container is captured by the bag. Filtered and discharged to the outside. During drying, due to gas-solid two-phase countercurrent contact, vigorous agitation. The solid particles are suspended in a drying medium and have a large contact surface area, which is excellent in heat transfer, mass transfer, volume dry strength, and thermal efficiency.
Because the boiling dryer has better adaptability to various materials, it has smaller floor space, larger production capacity, higher thermal efficiency, easier operation control and less particle damage than other dryers. It is widely used at present, especially in pharmaceuticals. In the industry.
1.2 Features of fluidized bed dryer
1.2.1 Because the contact area between the material and the drying medium is large, and the material is continuously stirred vigorously in the bed, the heat transfer effect is good and the heat capacity coefficient is large;
1.2.2 Due to the uniform temperature distribution in the fluidized bed, any local overheating of the product is avoided, so it is especially suitable for drying certain heat sensitive materials;
1.2.3 Continuous operation can be carried out in the same equipment, and intermittent operation can also be performed;
1.2.4 The residence time of the material in the dryer can be adjusted as needed, so the moisture content of the product is stable;
1.2.5 The drying device itself does not include mechanical moving parts, so the investment cost of the equipment is low and the maintenance workload is small.
Fluid bed dryer can be used for drying powder sugar, granule sugar, sandy sugar, sand sugar, also for Food powder or granule drying, chemical powder drying, medicine powder drying.
Used for boiling drying of particle material with a size of 0. 1-6mm, and suitable for speedy drying of finished product, intermediate (semi finished product) in such trades as pharmaceutical, food, light industry and chemical etc.
