   Production in the dairy industry, a reasonable selection of advanced machinery and equipment, to ensure product quality, reduce operation and maintenance costs and increase the competitiveness of dairy products and economic efficiency, and promote the development of dairy industry and the technological advances of great significance. In liquid milk, the selection process for aseptic filling equipment and is particularly prominent, but there are also a selection of equipment to reduce operating costs.

     Industrial production of milk falling film evaporator design and selection of the traditional design of falling-film evaporator is the use of steam by increasing the number of (single-effect multi-effect variable) to achieve the purpose of saving energy and reducing consumption. However, the effect of an increase in the number of steel consumption increased by leaps and bounds, the cost is doubled, due to restrictions on heat transfer temperature difference, the increase in efficiency generally does not effect more than seven. With steam-jet pump, the use of hydraulic jet of double-effect falling film evaporator for the common falling-film evaporator design.
