The main feed machinery is mainly composed of feeding, mixing, granulating, transmission and lubrication systems. Its working process is to require the mixed powder with a water content of not more than 15%, enter the feeding auger from the hopper, adjust the speed of the stepless speed regulation motor to obtain a suitable material flow, and then enter the agitator, stir and steam through the stirring rod Mixing and conditioning. If you need to add molasses or fat, add it from the mixing drum to conditioning with steam. The amount of fat added is generally not more than 3%, otherwise it will be difficult to form. After conditioning, the temperature of the mixed powder can reach 64～85℃ , Humidity reaches 14～16%. Then pass through the chute through the optional iron absorption device to remove the iron impurities mixed in the powder, and enter the pressing chamber for granulation.
