Silicon carbon spiral dryer

1、 Product Introduction

Shanghai MinjieSilicon carbon spiral dryerIt is the core specialized equipment under the VSD continuous drying system, relying on the company's 25 years of vacuum drying technology accumulation, specially tailored for powder/particle materials with high purity requirements, heat sensitivity, and easy agglomeration. The equipment innovatively integrates silicon carbon heating technology and spiral dynamic drying structure, strictly follows GMP standard design, and uses food grade and pharmaceutical grade 304/316L stainless steel contact materials to achieve continuous and pollution-free treatment of materials from wet state to dry finished products. Its core advantage lies in low-temperature efficient drying and purity maintenance, which is widely used in industries such as chemical, electronics, new materials, and pharmaceuticals. It is particularly suitable for large-scale production of materials sensitive to purity and temperature, such as silicon carbide powder and special ceramic powder. It is a professional drying solution that balances efficiency, quality, and environmental protection.

2、 Working principle

1. Continuous feeding and uniform distribution: Wet materials are stably fed into the drying machine through a dedicated continuous feeder, and evenly dispersed through a spiral conveying structure to avoid material accumulation and ensure an enlarged heating area.

2. Silicon carbon heating and temperature control: Using high-performance silicon carbon heating element as the core heat source, its high temperature resistance and oxidation resistance can achieve precise temperature control in a wide range of 20-300 ℃. Heat is evenly transferred to the material through conduction, and the heating is fast and the temperature stability is strong.

3. Vacuum environment enhanced drying: The equipment quickly builds a stable vacuum chamber, reduces the boiling point of water or solvents in the material, and can achieve rapid evaporation at low temperatures, avoiding material denaturation and purity decrease caused by high temperatures.

4. Spiral dynamic efficiency enhancement: Spiral blades continuously stir while conveying materials, breaking the surface gas film of the materials, enhancing heat and mass transfer efficiency, avoiding local overheating or agglomeration, and ensuring uniform drying.

5. Continuous discharge and medium recovery: The dried finished product is automatically output by a vacuum continuous discharge device, with no retention throughout the entire process; The water vapor or organic solvent vapor generated by evaporation is centrally processed through a condensation recovery system, which not only meets environmental requirements but also improves resource utilization efficiency.

3、 Product advantages

1. Low temperature high fidelity drying: Silicon carbon heating combined with vacuum environment achieves low-temperature drying within an adjustable temperature range of 20-300 ℃, maximizing the retention of active ingredients and original physical and chemical properties of materials, especially suitable for maintaining the purity of high-purity materials.

2. Excellent drying efficiency: Silicon carbon heating element heats up quickly and has high thermal efficiency. Combined with spiral dynamic stirring and vacuum strengthening, the material drying cycle only takes 20-80 minutes, and the water evaporation rate can reach 8-150kg/h (depending on the model), which is more than 40% more efficient than traditional drying equipment.

3. adaptabilityexcellentOptimized design for high viscosity, easy to agglomerate, and heat sensitive materials, it can handle various powder/particle materials with a feed moisture content of 10% -80%. The dry material moisture content can be accurately controlled at 0.3% -5%, suitable for special material requirements such as silicon carbide powder and ceramic powder.

4. Safety and environmental compliance: The fully enclosed system design avoids dust flying and material pollution, complies with GMP standards and environmental requirements; The part in contact with the material is made of 304/316L stainless steel, and special materials can be selected as needed, with no risk of material precipitation.

5. Energy saving and economical operation: Silicon carbon heating element has low power consumption and long service life. With heat recovery design, the operating cost is significantly lower than traditional heating and drying equipment; Fully automated control, requiring only 1-2 operators, significantly reducing labor costs.

6. Easy operation and maintenance: Adopting a PLC fully automatic control system, precise control of temperature, vacuum degree, feeding speed and other parameters, no manual intervention is required after one click start; The equipment structure is streamlined, with fewer vulnerable components, supporting online cleaning, long maintenance cycles, and low costs.
