Introduction：
◆ Jinling is a professional manufacturer of vacuum paddle dryers. This model is the third-generation product designed and upgraded by our company.
◆ Our company made a series of innovative improvements to the system in 2003, mainly focusing on thermal expansion, concentricity, shaft sealing, discharge valve, transmission structure, mixing mechanism, strength of main shaft, shaft heating, bearing structure, internal structure of mechanical seal, etc. Overall, mechanical seals can be used for vacuum drying instead, which has greatly improved the sealing performance and service life. This model is also applicable for large-scale drying machines with high vacuum level.
◆ The mechanical seal structure is mainly used to maintain a high vacuum level for a long time and effectively prevent impurities from entering the material. Generally, single-end mechanical seals, corrugated mechanical seals and double-end mechanical seals are used. The end-face materials are generally graphite, silicon carbide, and alloy steel.
◆ In order to ensure the airtightness and the service life of the dryer, a series of innovative designs and processing techniques have been applied, especially for the materials with high resistance towards abrasion and corrosion, such as salts, liquids, solvents, etc., in order to significantly improve the performance of equipment in terms of shaft runout, expansion and extension, stability, and the service life. Our company is currently the top-class manufacturer of vacuum paddle dryers domestically.
◆ Jinling developed and designed different paddle blade structures for different drying conditions: spiral belt style, shoveling plate style, disc style, triangular stirring paddle style, coulter style, etc. Also, heating method inside the shaft can be designed to increase specific surface area and improve drying efficiency.
