Amino acid and double cone rotary vacuum dryer is widely used in pharmaceutical, chemical, food, dye, powder metallurgy powder, granular (including goods like) drying.
Amino acid (amino acid): a general term for a class of organic compounds containing amino and carboxyl groups. The basic unit of the biological function of macromolecular protein, constitute the basic material of animal nutrition required protein. Organic compounds containing a basic amino acid and a carboxyl group. Amino connected to the alpha carbon of α - amino acids. The amino acid composition of protein are alpha amino acid.
The intermediate acid special double cone rotary vacuum dryer body is cylindrical, both ends is conical, conical top, a discharge port (used as a manhole, tank), is divided into three layers, the intermediate jacket heating medium can be steam or hot water circulation, heat preservation layer of alkaline superfine glass cotton, inner energy consumption; delivering material, rotary drying under vacuum conditions, material edge flip side of through wall heat gain, to speed up the drying, so as to avoid the heat sensitive materials in the drying surface yellowing phenomenon, and greatly shorten the drying time, drying time only for similar materials needed in vacuum oven is about 2/3, improving labor productivity; especially suitable for easy oxidation and flammable, explosive materials and drying heat sensitive materials; in the strict requirements without damaging the product shape material, metal material limited and discharging volatiles (or toxic substances) to recovery (or destroy toxic) material, more can show its superiority.
Advanced technology with vacuum vacuum pipe and the tank body synchronous rotation, so as to avoid the other manufacturers of equipment due to wear of cylinder and vacuum tube and cause the product to be residual material or sealing ring wear material pollution ills. Many enterprises in use, good effect has been widely praised. Considered the best measures at home and to solve this problem.
Both ends of the cylinder body adopts the most advanced rotary joint sealing, changed bad phenomenon before packing seal is easy to wear and tear drain vacuum.
Amino acid and double cone rotary vacuum dryer has the advantages of simple operation, convenient access to material, greatly reduces the labor intensity of workers, but also reduce the material in the drying process of the pollution of the environment, improve the quality of the products. In conformity with the "GMP" hardware requirements.
Silicon nitride, chemical formula Si3N4, is a kind of important ceramic materials. It is a kind of super hard material, itself with lubrication, and wear resistance, as the atomic crystal; high temperature oxidation. But it can also resist the impact of hot and cold, the air is heated to 1000 ℃, rapid cooling and rapid heating, also won't break. It is because of silicon nitride ceramics is so excellent, people often use it to manufacture bearings, gas turbine blade, mechanical permanent mold ring, seals and other mechanical components. If the heating surface with high temperature resistance and not easy to manufacture silicon nitride ceramic heat engine components, not only can improve the quality of diesel engine, fuel saving, but also can improve the thermal efficiency. China and America, Japan and other countries have developed this kind of diesel engine.
Silicon nitride used as high-grade refractory materials, such as SiC combined with SI3N4-SIC refractory used for blast furnace and other parts; and the BN node cooperation SI3N4-BN material, used for horizontal continuous casting of separating ring. SI3N4-BN series horizontal continuous casting of separating ring is a fine structure of ceramic materials, uniform structure, high mechanical strength. The thermal shock resistance is good, and not by the steel liquid wetting, to meet the requirements of renju process.
Silicon nitride special double cone rotary vacuum drying machine working principle:
SZG double cone rotary vacuum dryer is a double conical rotary tank, equipment the middle cylindrical, both ends is conical, conical top head is designed to open the feeding (and manhole), another end for discharging valve. The tank body, is divided into three layers, the intermediate jacket heating medium can be steam, hot water or heat conducting oil circulation, heat preservation layer of alkaline superfine glass cotton, energy consumption; the inner layer on the material. When the tank in a vacuum state, the jacket is filled with heat conducting oil, hot water or steam, heat medium is heated, heat transfer to the wet material through the inner wall of the tank.
As the silicon nitride special double cone rotary vacuum dryer tank body is in a vacuum state, the solvent of various materials (including water) under the condition of vacuum can be rapidly vaporized in temperature lower, and the rotary material constantly, and turning, surface material constantly more new and wall contact in order to make full use of the wall, the conduction of heat, drying speed, improve the drying efficiency, and can achieve the purpose of uniform drying.
Solvent wet materials after heat absorption evaporation (water vapor), through the vacuum pump vacuum suction tube is withdrawn. Midway through the low temperature condensation system (use tap water or frozen brine) for cooling, in order to achieve the purpose of recycling, saving the production cost, and improve the vacuum pump working conditions, but also reduce the pollution of the environment. |
