The microorganism fermented feed can improve the production performance, enhance immunity and improve meat quality in pigs, and the production of fermented feed is solidstate fermentation in domestic. In order to produce fermented feed in feeding field and automatic feeding, an automatic fermenting and feeding equipment was designed. The equipment was composed of feed fermentation system, PLC and PIC MCU control system and feeding system. The complete diet mixed with bacterial liquid was placed in the hopper, and conveyed to the transverse screw conveyor through the metering grooved wheel under the hopper, and then conveyed to the fermentor by a longitudinal screw conveyor. In the screw conveyors, bacteria and feed were fully mixed. The fermentor was designed with 100L in volume and 7 in number, which can ensure punctual feeding for different breeding objects. When fermentation was over，feed was layout from the fermentor to the feeding vehicle automatically, and then discharged into different trough quantitatively. The PLC system and the PIC MCU system constituted the control system, and wireless communication was used between them. The operator only needed to pour the feed to be fermented into the hopper, and then set the parameters of the fermentation time, the volume of the feed and the feeding object in the humancomputer interface. This equipment would automatically accomplish the whole process from fermentation to feeding. The test result showed that the volume errors of screw conveyors and feeding vehicle were both less than 6%; the positioning error of feeding vehicle to the troughs was less than 11.75mm; the parameters included fermentation time, feeding object and feeding vehicle speed were controlled accurately. The equipment worked stable and reliable, which can reduce labor intensity significantly and meet the requirements of solidstate fermented feed production and feeding in feeding field.
