Product overview
SZG double cone vacuum dryer is a new generation drying device developed by our factory in combination with similar domestic product technology. Double cone vacuum has two-stage elastic connection mode of belt and chain, so the equipment runs stably. The specially designed tooling fully reflects the good concentricity of the two shafts. The reliable American technology rotary joint is used for the heat medium and vacuum system. On this basis, we developed szg-a, which can not only stepless speed regulation, but also constant temperature control.
Application scope
It is applicable to the concentration, mixing and drying of powder, granular and fiber in chemical, pharmaceutical, food and other industries, as well as the materials that need low-temperature drying (such as biochemical products), more suitable for the drying of materials that are easy to oxidize, volatilize, heat sensitive, strongly irritating and toxic, and materials that are not allowed to destroy the crystal.
Working principle
Heat energy (such as hot water, low-pressure steam or heat transfer oil) is introduced into the sealed interlayer, and the heat is transmitted to the dried material through the inner shell. Driven by power, the tank rotates slowly, and the materials in the tank mix continuously, so as to achieve the purpose of intensified drying. When the material is in vacuum state, the water (solvent) on the surface of the material will be saturated and evaporated due to the decrease of steam pressure, and then discharged and recovered by vacuum pump in time. The water (solvent) in the material continuously permeates, evaporates and discharges to the surface. The three processes are carried out continuously, and the material is dried in a short time. The product features: when the oil is heated, it adopts automatic constant temperature control, which can dry biochemical products and mineral raw materials, and the temperature can be between 20-160 ℃. High thermal efficiency, more than 2 times higher than ordinary oven. Indirect heating, materials will not be contaminated, in line with the "GMP" requirements. The equipment is easy to maintain and clean.
