Potassium sulfate special disc dryer

Potassium sulfate material description:

Colorless or white crystals, particles or powders. No odor. Taste bitter. Hard in texture. Stable in the air. 1g dissolved in 8.3ml water, 4ml boiling water, 75ml glycerol, insoluble in ethanol. Potassium chloride and ammonium sulfate can increase their solubility in water, but they are almost insoluble in saturated solutions of ammonium sulfate. The aqueous solution is neutral with a pH of approximately 7. The relative density is 2.66. Melting point 1067 ℃. The main uses include biochemical testing of serum proteins, catalysts for Kjeldahl nitrogen determination, preparation of other potassium salts, fertilizers, drugs, preparation of glass, alum, etc.

The function and use of potassium sulfate material:

It is the basic raw material for manufacturing various potassium salts such as potassium carbonate, potassium persulfate, etc. Glass industry is used as a settling agent. Used as an intermediate in the dye industry. The spice industry uses it as an additive, etc. The pharmaceutical industry also uses it as a laxative. Potassium sulfate is a commonly used potassium fertilizer in agriculture, with a potassium content of about 50%, commonly known as "Baijiali" in Taiwan. In addition, potassium sulfate is also used in industry for glass, dyes, fragrances, pharmaceuticals, and more.

Working principle of potassium sulfate special disc dryer:

The wet material is continuously added to the upper layer of the dryer's drying disc from the feeder, and the rake arm with rake blades rotates to make the rake arm rotate and make the rake blades continuously flip the material. The material flows along an exponential spiral over the surface of the drying disc, and the material on the small drying disc is transferred to the outer edge, where it falls onto the outer edge of the large drying disc below. The material moves inward on the large drying disc and falls into the next layer of small drying disc from the middle discharge port. The drying plates of different sizes are arranged alternately up and down, allowing the material to flow continuously through the entire dryer. A hollow drying tray is filled with heating medium, which includes saturated steam, hot water, and thermal oil. The heating medium enters from one end of the drying tray and exits from the other end. The dried material falls from the drying tray at the bottom of the shell, and is then transferred to the discharge port by the rake blades. Moisture escapes from the material and is discharged through the dehumidification port located on the top cover. The moisture in the vacuum disc dryer is discharged through the vacuum pump port located on the top cover. Dry materials discharged from the bottom layer can be directly packaged. By adding auxiliary equipment such as fin heaters, solvent recovery condensers, bag filters, dry material mixing mechanisms, and induced draft fans, the production capacity of drying can be improved. Drying paste like and heat sensitive materials can facilitate solvent recovery and enable pyrolysis and reaction operations.
