As the fast developing of chemical industry, there are many kinds of rubber product with similar producing process, mainly including: raw material preparing, Plastic refining, mixing, calendering, forming, vulcanizing etc., and most of these sections needs steam. Besides, some high temperature machines such as pressing, kneading, banbury machines, vulcanization molding, injection molding machine, cement mixer, conveyor belt dryer and molds heating and insulation also need thermal oil heater.
The boilers of food factories are mainly used in the process of distillation, disinfection, drying and maturation in food processing, and the high temperature steam is used for high temperature cooking, drying and disinfection of food. Therefore, steam boilers have the highest application frequency, mainly conveying steam through pipelines, requiring constant steam temperature, constant pressure, and even the quality of steam determines the quality of food products. Some food factories also use hot water boilers for central heating of their plants, office buildings, or special processing of certain foods.The boilers of food factories are mainly used in the process of distillation, disinfection, drying and maturation in food processing, and the high temperature steam is used for high temperature cooking, drying and disinfection of food.
