Structure composition of Antioxidant 168 Vacuum Horizontal Disc Dryer
In the industrialized production of antioxidant 168, vacuum horizontal disc dryer plays an important role. By controlling the parameters of drying temperature, vacuum degree and material residence time, it successfully reduces the water content of antioxidant 168 to below the specified standard, and the purity and particle size of the product meet the requirements of high quality, which effectively improves the competitiveness of the product in the market. At the same time, the equipment is stable and reliable in the process of operation.
Meanwhile, this equipment is stable and reliable in operation, easy to operate and low maintenance cost, which brings good economic and social benefits for the enterprise.
(1) Cylinder: as the shell of the dryer, it is usually made of stainless steel and other materials with good corrosion resistance and sealing to ensure that the drying process is carried out in a vacuum environment. The inner wall of the cylinder is generally with a jacket, which can be passed into the steam, thermal oil and other heating media to provide heat for drying.
(2) Disc spindle: It is one of the core components of the dryer, the spindle is hollow design, steam is passed into the interior and distributed to the disc so that the disc can be heated evenly. Condensate and non-condensable gas are discharged from the end of the shaft through the rotary joint.
(3) Disc: the disc is usually installed on the main shaft, its surface is smooth, not easy to scale or wear, with good heat transfer performance. The outer edge of the disk is equipped with a curved plate, which can guide the material along the cylinder toward the discharge port.
(4) Transmission mechanism: it is composed of motor and deceleration mechanism, etc. It is used to drive the main shaft to rotate, thus driving the disc and rake leaves to move, so that the materials are constantly turning and moving on the disc to realize uniform drying.
(5) Steam heating system: including rotary joints, metal hoses, traps, shut-off valves, ball valves, sight holes and steam separator and other components, its role is to ensure that the spindle disc always maintains saturated steam state, and can be discharged smoothly condensate to ensure that the heating effect and the normal operation of the equipment.
Antioxidant 168 Vacuum Horizontal Disc Dryer Technical Advantages
(1)High drying quality
Low-temperature drying and anti-oxidation: working in a vacuum environment, it can reduce the boiling point of solvent in the material, so that the drying process can be carried out at a lower temperature, which effectively avoids the risk of oxidization and deterioration of Antioxidant 168 at high temperature, and ensures the stability of product quality and performance.
Avoiding material pollution: adopting indirect heating mode, the heating medium is not in direct contact with the material, the material will not be contaminated, which is in line with the relevant production requirements and ensures the purity and quality of Antioxidant 168.
(2)High drying efficiency
High-efficiency heat transfer: the disc surface is smooth and has good heat transfer performance, the built-in blade is deep into the material layer, which can make full use of the heat transfer area, so that the heat exchange between the material and the heating medium is more adequate, accelerate the drying speed and improve the drying efficiency.
Rapid evaporation: the vacuum environment makes the moisture and solvent in the material can be quickly evaporated at a lower temperature, the moisture evaporation rate is fast, the drying speed is also accelerated, which can greatly shorten the drying time and improve the production efficiency.
(3) Uniform material handling: the rotating disc is equipped with scraper, which can prevent the material from bonding and piling up on the surface of the disc, and at the same time ensure the uniform distribution and turning of the material on the disc, so as to make the drying of the material more uniform and avoid the phenomenon of local overheating or incomplete drying, thus guaranteeing the consistency of the product quality of the whole batch of Antioxidant 168.
(4)Easy operation and maintenance
Simple operation: the equipment runs stably and is easy to operate, supporting continuous or intermittent operation. The operator can easily realize the control of the drying process by adjusting the relevant parameters, such as the material flow rate, heating temperature, spindle speed, etc., so as to meet different drying requirements.
Low maintenance cost: the structure of the equipment is relatively simple, no complex transmission parts, low vibration and low noise during operation, reducing the failure rate and maintenance cost of the equipment, and the cleaning and maintenance of the equipment is also more convenient, easy to maintain the cleanliness and hygiene of the equipment to ensure the normal production.
(5) Safety and environmental protection is good
Safe and reliable: the whole drying process is carried out in a closed environment, which is suitable for dealing with toxic, odor or flammable and explosive wet materials, and can effectively prevent material leakage and dust flying, reduce the safety risks in the production process, improve the operating environment and reduce the hazards to the operators.
Energy saving and environmental protection: adopting conduction heating method, the heat is directly transferred to the material, the heat loss is small, compared with the traditional hot air drying and other ways of energy consumption is low. At the same time, the equipment can be equipped with a solvent recovery device to recover and reuse the volatile solvent, which not only reduces the waste of resources, but also reduces the pollution of the environment, in line with the requirements of environmental protection and resource conservation.
(6) Wide range of application: it can use a variety of heat transfer media, such as steam, thermal oil or hot water, etc., and can flexibly adjust the drying temperature, material residence time and other parameters according to different material characteristics and drying requirements, applicable to the drying of antioxidant 168 materials of various forms and properties, and can also be widely used in pharmaceutical, chemical, food, dyestuffs, and other industries for drying.
