Description
(Sodium Fluoride Powder) Spray Dryer is the most widely used process in liquid shaping technology. It is suitable for producing powder and granules solid products from solution, emulsion, soliquoid, and pumpable paste materials. Therefore, when the particle size, final moisture, bulk density and granules shape meet the accurate standard, centrifugal spray drying is a ideal drying process.
Working Principle:
Liquid material is atomized through a special pressure nozzle with a high-pressure pump. Hot air enters the dryer after being adjusted by an air distributor. The material and hot air is mixed in the dryer, rapidly carries on heat and mass transfer. Powder or granular products are produced in a very short time. Products with larger particles size are discharged from the bottom of the dryer, smaller particles enter the cyclone with hot air. The exhaust gas is discharged into the air after dust removal in a scrubber. The dryers can be divided into high, middle and low-pressure spray dryers according to different pressures of atomization, while taking into account different flow fields, they are divided into co-current, fountain mode and counter-current spray dryers.
Characteristics:
1. High operational flexibility on non-adhesive or low-adhesive liquid materials.
2. Simple structure of the spray nozzle, easily used and maintained.
3. Less power consumption, low cost.
4. The hollow spherical product with big particles, good mobility and solubility.
5. Can be used to spray-cooling granulation process, such as paraffin, grease particles, special resins, etc.
Applicable Materials
Sodium Fluoride Powder
Sodium fluoride (NaF) is an inorganic compound with the formula NaF. It is used in trace amounts in the fluoridation of drinking water, toothpaste, in metallurgy, as a flux, and is also used in pesticides and rat poison. It is a colorless or white solid that is readily soluble in water. It is a common source of fluoride in the production of pharmaceuticals and is used to prevent dental cavities.
Food: Amino acid, vitamin, egg powder, bone powder, protein, milk powder, blood powder, soy sauce powder, coffee, tea powder, glucose, pentadiene carboxylic acid, pectin, flavours, vegetable juice, yeast, starch, etc.
Ceramic: Alumina, zirconia, magnesium oxide, Titania, pottery clay, china clay, all kinds of magnetic porcelain and metal-oxides, etc.
Chemical: Aluminum polychloride, disperse dyes, reactive dyes, organic catalyzer, white carbon black, washing powder, zinc sulfate, silica, sodium metasilicate, potassium fluoride, calcium carbonate, potassium sulfate, inorganic catalyzer, wasted liquid, etc.
