1. Zhengchang microliquid adding system fits the demand of the national market and fills up the blank of the country，fitting the continual surface spraying of microelement like liquid enzyme and oil to finished pellet feed.
2. The system tests the instantaneous material weight of the flow scale, according to set adding proportion,adjust the liquid flow automatically through the metering pump,the liquid after atomization sprayed in pellet feed surface evenly,have the functions of stopping spraying automatically when lack of liquid and giving alarms when error happens.
3. The system could be added several kinds of nutrient substance with small quantity mixed through stirring pipe producing atomization sprayed in the material surface, the adding quantity is less than 0.2L/H, having water atomization and gas atomization for option.
4. High degree of automation,easy operation and convenient installation.
