The stainless steel reactor has the characteristics of rapid heating, high temperature resistance, corrosion resistance, sanitation, no environmental pollution, automatic heating of the boiler, and convenient use. The stainless steel reactor is widely used in petroleum, chemical, rubber, pesticide, dye, medicine, Food, used to complete the vulcanization, nitrification, hydrogenation, alkylation, polymerization, condensation and other processes, is based on the full mixing of the reacting substances, and requires the use of physical changes such as heating, cooling, liquid extraction, and gas absorption. Only the stirring device can achieve good results, and the outer coil reactor can be designed and processed for customers.
