Dark purple orthogonal monoclinic crystals are irritating. Used in the fields of glass manufacturing, printing and dyeing and chromium catalysts. It is obtained by reacting chromium trioxide with nitric acid and reducing it with sucrose.
Special dryer for chromium nitrate Product overview:
SZG double cone vacuum dryer is a new generation drying device developed by our factory in combination with domestic similar product technology. Double cone vacuum adopts belt-chain two elastic connection method, so the equipment runs smoothly. The specially designed process fully embodies the good concentricity of the two shafts. The heat medium and vacuum system use reliable mechanical seals or American technology rotary joints. On this basis, we have developed SZG-A which can be used for both stepless speed regulation and constant temperature control.
As a professional drying equipment manufacturer, our products are made from high-temperature heat-conducting oil, medium-temperature steam and low-temperature hot water. When drying viscous materials, the factory will specially design a [copy board" mechanism or set balls in the tank.
Special dryer for chromium nitrate Working principle:
◎Into the closed interlayer, heat energy (such as hot water, low-pressure steam or heat-conducting oil) is introduced, and heat is transferred to the dried material through the inner casing.
◎ Under the power drive, the tank body rotates slowly, and the materials in the tank are continuously mixed to achieve the purpose of strengthening and drying.
◎The material is in a vacuum state, the vapor pressure drops so that the water (solvent) on the surface of the material reaches a saturated state and evaporates, and is discharged and recovered in time by a vacuum pump. The water (solvent) inside the material continuously permeates, evaporates and discharges to the surface, and the materials are continuously dried in a short time.
Special dryer for chromium nitrate
It is suitable for the concentration, mixing, drying and low-temperature drying of powders, granules and fibers in chemical, pharmaceutical and food industries (such as biochemical products). It is more suitable for drying of materials that are easily oxidized, volatile, heat sensitive, strongly irritating, toxic materials and materials that are not allowed to damage crystals.
Special dryer for chromium nitrate Features:
◎ When the oil is heated. Automatic constant temperature control. Can dry biochemicals
◎ and mineral raw materials, the temperature can be between 20 ~ 160oC.
◎ High thermal efficiency, more than 2 times higher than the average oven.
◎ Indirect heating. The material will not be contaminated and meet the requirements of [GMP". Equipment maintenance is easy and easy to clean.
◎Recommended process placement demonstration solvent recovery process placement.
How to judge the quality of the double cone rotary vacuum dryer?
Double cone rotary vacuum dryer is suitable for vacuum drying and mixing of powder and granular materials in medicine, food, chemical and other occupations. It is especially suitable for materials with the following requirements:
Heat sensitive materials that cannot withstand high temperatures:
Simple oxidation, risky materials;
Materials that need to recover solvent and toxic gases:
a material that requires a very low residual volatile content;
Demand ample, uniform material.
How to judge and test the quality of the double cone rotary vacuum dryer? Just start with the appearance and quality of the double cone rotary vacuum dryer.
1) View the appearance quality of the double cone rotary vacuum dryer, including: welding and appearance of metal components such as double cone rotary vacuum dryer frame, double cone can body, etc., whether there are manufacturing defects, fillers at the junction of vacuum tubes, and sealing situation.
2) Investigate the accuracy of the seal manufacturing of the inlet (outlet) of the rotary can of the double-cone rotary vacuum dryer, and the manufacturing condition of the upper operating member.
3) The mechanical transmission of the double-cone rotary vacuum dryer has some equipment conditions, and the noise of the operation is large.
4) Electrically, the double-cone rotary vacuum dryer button station is not safe, beautiful and dustproof. That is, these are the first few. First of all, consider: safe operation, no problem, manufacturing level, equipment life and so on.
