Development of chemical process equipment Development of a new type of vacuum rake dryer He Deqiang Yue Yongfei Zhang Yi Zhao Xinyi (Tianhua Chemical Machinery and Automation Research and Design Institute, Lanzhou, 730060) Table 1 Application data of a new type of vacuum rake dryer Material name Wet composition Allowed Drying temperature / °C Humidity (wet basis) /% Drying time per batch A Solvent recovery /% Thermal efficiency /% Feeding products New Other New Other Shampoo Additives Water and ethanol Pesticide intermediates MIBK and methanol Drying from Table 1 In terms of time, solvent recovery and thermal efficiency, the new vacuum rake dryer is significantly better than the conventional vacuum rake dryer.
4 Conclusion The heat transfer effect is good. Under the same operating conditions, the new vacuum rake dryer can shorten the 1/2 drying residence time compared with the conventional vacuum drying equipment; the solvent recovery rate is as high as 85%, especially for materials containing precious The solvent drying operation can greatly reduce the production cost of the product; this type of dryer can be used in vacuum drying operations with large output, and the heat transfer effect is much higher than the small vacuum rake dryer; due to the special sealing structure, The dried material has no potential for contamination, and is particularly suitable for the drying of special materials such as medicines and spices. It has a high thermal efficiency of up to 80% and saves energy.
It can be seen that the new type of vacuum rake dryer shortens the residence time of the material in the dryer, has good sealing performance and high thermal efficiency, and can meet the demand for large-sized dryers.
