Abstract
A continuous constant-rate feeding system includes at least one storage unit, a scratching unit and a water-cooled screw feeding unit. The storage unit includes a tank and an agitator. The tank stores material and includes upper and lower chambers. The agitator is rotationally located in the upper chamber for agitating the material. The scratching unit includes upper and lower scratchers and a material divider. The upper scratcher is located in the upper chamber and can spin to convey the material from the upper chamber into the lower chamber. The lower scratcher is located in the lower chamber and can spin to convey the material from the lower chamber into the water-cooled screw feeding unit. The material divider locates between the upper and lower chambers and spin automatically or manually to fall the material from the upper chamber into the lower chamber through a specific aperture alternately.
