I. silica gel project overview:
Silicon rubber is a kind of high active adsorption material, which belongs to amorphous material. Its chemical formula is msio2 · nH2O. Insoluble in water and any solvent, non-toxic and tasteless, stable in chemical properties, no reaction with any substance except strong base and hydrofluoric acid. Different types of silica gel have different microporous structures due to different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that can not be replaced by other similar materials: high adsorption performance, good thermal stability, chemical stability, high mechanical strength, etc. Silica gel can be divided into: macroporous silica gel, macroporous silica gel, B-type silica gel and microporous silica gel according to its pore size.
II. Overview of silica gel special boiling dryer equipment:
It is composed of air filter, fluidized bed main engine, cyclone separator, bag filter, high-pressure centrifugal fan and operation platform. Due to different properties of dry materials, when supporting dust removal equipment, it can be considered as required, and cyclone separator, bag type dust remover or one of them can be selected at the same time. Generally speaking, only the cyclone separator is needed for drying the powder and particle materials with large proportion. Small granular and powdery materials with light specific gravity need to be equipped with bag type dust remover, and equipped with pneumatic feeding device and belt conveyor for selection.
The granular solid materials are added into the fluidized bed dryer by the feeder. After the filtered clean air is heated, it is sent to the bottom of the fluidized bed by the blower and contacted with the solid materials through the distribution plate, forming a fluidized state to achieve the heat and mass exchange of gas and solid. After drying, the material is discharged from the discharge port, and the waste gas is discharged from the top of the boiling bed, and then the solid powder is recovered by the cyclone dust collector group and the bag dust collector, and then discharged.
Steam, electricity and hot air stoves can be matched (matching according to the user's requirements).
It is suitable for the drying of granular materials, such as APIs, tablet pressing granules, traditional Chinese medicine granules, plastic resins in chemical raw materials, citric acid and other powdery and granular materials, as well as the drying of food and beverage granules, grain processing, corn germ, feed, etc. The particle size of the material can be up to 6 mm, preferably 0.5-3 mm.
