With the improvement of modern living standards, people are increasingly demanding the quality of fresh milk and dairy products, and the demand is increasing. It can be said that fresh milk and dairy products have become one of the indispensable foods for people. The boiler is an indispensable energy equipment in the production process of the dairy industry. The steam generated by the boiler is widely used in the processes of distillation, disinfection, drying and shaping in the processing of dairy products. To produce high grade dairy products whilst maintaining low production costs, it is essential that dairy processes are operated as efficiently as possible, making effective use of the heat available in the steam.
From the boiler house the steam is carried to processes within the dairy by the distribution system, where it should be available at the correct pressure, in sufficient quantity and in the best possible condition. Steam is used in the dairy for indirect heating, direct heating and sterilization processes. These applications will include:
Hot water heaters.
Indirect plate heat exchangers.
Clean in place (CIP) units.
Sterilize in place (SIP) systems.
Steam jacketed vessels for processing butter oil.
Multi-effect evaporators used to produce condensed milk.
Aseptic storage to provide a sterile barrier on product change over in pipework and tanks.
Dairy effluent holding tanks (waste fat) are kept warm to prevent solidification prior to disposal.
Direct UHT sterilizers used to pasteurize milk at higher temperatures.
Air heater batteries which provide hot air for spray drying and can drying.
Two main types of steam boilers are used for dairy industry: the fire tube boiler (which is the most common type in dairies) and the water tube boiler. Expect the dairy processing, ZBG provide various types of steam boilers to some other applications like food industry, rubber industries, paper industry, plywood industries, textiles, pharmaceutical industries etc.
