Problems solved by technology

[0003] In the process of producing silicone resin, the traditional drying method, one is to remove the solvent in the original production equipment to obtain the product, and the other is to enter the spray drying system through the pipeline, and the product is obtained after spray drying; the characteristic of the first method is that when the product When the content of the solvent is not required to be high, it is convenient to obtain qualified products. When the content of the solvent is not higher than 3%, it is difficult to obtain qualified products by this method, and it is easy to obtain a qualified product during the process of removing the solvent and drying. Due to the high temperature, the material turns yellow and deteriorates; although this method is simple to recover the solvent and does not pollute the environment during the process of recovering the solvent, the drying efficiency of this method is low, which greatly affects the production efficiency. The second method can be a good solution In the first method, the finished product requires low solvent content, and the production efficiency has also been greatly improved; but the problem in the second method is that the solvent is difficult to recycle, which causes great harm to the environment
