The machine has advanced technology, reasonable design, compact structure, wide application range, large production capacity, good product quality and high efficiency, and its performance reaches the international advanced technical level.
Summary of sodium bromate:
Sodium bromate is a colorless crystalline, white particle or crystalline powder. No smell. At 381 ℃, oxygen is released. It is soluble in water, insoluble in ethanol, and the aqueous solution is neutral. The relative density was 3.34. It is oxidizing. Friction with organic matter, sulfide and easy oxide can cause combustion or explosion. It's irritating. It is mainly used for the preparation of inorganic chemical products and chemical reagents for the determination of phenols. It is also used as an oxidant. Daily chemicals are used in the production of perms. It is used as analytical reagent, oxidant and perm agent, and mixed with sodium bromide as gold dissolving agent.
Special dryer for sodium bromate:
Sodium bromate dryer is an efficient conduction type continuous drying equipment. Its unique structure and working principle determine that it has the characteristics of high thermal efficiency, low energy consumption, small floor area, simple configuration, convenient operation and control, and good operating environment. It is widely used in the drying operation of chemical, pharmaceutical, pesticide, food, feed, agricultural and sideline products processing industries. It is well received in the practice of various industries. At present, we produce three types of atmospheric pressure, airtight and vacuum, 1200, 1500, 2200, 3000, four kinds, a (carbon steel), B (contact material parts are evenly distributed stainless steel), C (based on B, the steam pipeline, main shaft and support are stainless steel, and the cylinder and cover are lined with stainless steel). Three kinds of materials, drying area of 4 ~ 180m2, a total of hundreds of types of series products, and can provide matching auxiliary equipment, can meet the needs of users for drying various materials.

Principle of sodium bromate dryer
The wet material is continuously added to the first drying plate on the upper part of the dryer from the feeder, and the rake arm with rake blade makes rotary motion, which makes the rake arm rotate continuously. The material flows through the surface of the drying pan along the exponential helix, and the material on the small drying plate is transferred to the outer edge, and falls to the outer edge of the lower large drying plate at the outer edge. On the large dry plate, the material moves inward and falls into the following layer of small drying plate from the middle blanking port. Large and small drying plates are arranged alternately from top to bottom, so that materials can flow through the whole dryer continuously. The hollow drying plate is filled with heating medium in the form of saturated steam, hot water and heat conducting oil. The heating medium enters from one end of the drying plate and leads out from the other end. The dried material falls to the bottom layer of the shell from the last layer drying plate, and then is transported to the discharge port by the rake blade. The moisture escapes from the material and is discharged by the dehumidification port on the top cover, and the moisture in the vacuum disc dryer is discharged from the vacuum pump port on the top cover. The dry materials discharged from the bottom layer can be packaged directly. By adding fin heater, solvent recovery condenser, bag filter, dry material back mixing mechanism, induced draft fan and other auxiliary equipment, the drying production capacity can be improved. The drying paste and heat sensitive materials can be recovered conveniently, and the pyrolysis and reaction operation can be carried out.
Performance characteristics of special dryer for sodium bromate:
The residence time of materials can be adjusted.
The operation is simple and easy
The start-up and shutdown operation of dryer is very simple.
(3) low energy consumption
The solvent recovery device is simple and the recovery rate is high. For flammable, explosive, toxic and easy to oxidize materials, nitrogen can be used as wet carrier gas for closed-circuit circulation, so that it can be operated safely. It is especially suitable for drying flammable, explosive and toxic materials.
Vacuum type: disc dryer operated in vacuum, especially suitable for drying heat sensitive materials.
Due to the arrangement of drying tray and vertical installation, the drying area is very large and the floor area is very small.
