The use of corn steeping liquid is mainly to dry and concentrate the corn steeping liquid for the production of feed. To dry the corn steeping liquid needs to consume a lot of steam and heat. In today's increasingly tense energy sources, it brings great economic burden to enterprises. The germ and corn fiber separated during the processing of corn starch need to be dried by a tube bundle dryer. The secondary waste gas generated during drying byproduct passes through the cyclone dust collector and is directly discharged into the atmosphere by the fan. The secondary waste gas has a temperature of 90~110°C. High temperature, secondary waste gas is directly discharged, and a large amount of waste heat is not used, resulting in a great waste of energy.

The high-efficiency and energy-saving evaporation system for corn steeping liquid uses the secondary waste gas of the tube bundles produced during the drying process of corn germ and corn fiber separated from the corn starch processing process to evaporate and concentrate the corn steeping liquid, so that there is no need to use raw steam or Utilizing the heat in the condensed water in the tube bundle dryer, the drying and concentration of the corn steeping liquid can be realized only by using the exhaust gas, so as to save energy and reduce costs.
