This invention relates to a pre-treatment device and method for pig feed, belonging to the technical field of
pig farming equipment. It includes a mixing device, a
drive motor mounted at the bottom of the mixing device's outer shell, a mixing shaft at the output end of the
drive motor, a
discharge port on one side of the bottom of the mixing device's outer shell, a liquid inlet
pipe fitted onto the surface of the mixing device's outer shell, a
servo reduction motor mounted on one side of the top of the mixing device's outer shell, a gear mounted at the output end of the
servo reduction motor, and a toothed ring fitted onto the outer surface of the mixing shaft; a stirring rod
assembly is mounted on the surface of the mixing device. This invention integrates a stirring rod
assembly, a surrounding liquid inlet
pipe, a spiral deep kneading plate, a bottom baffle with micropores, and wall scraping strips into a pre-treatment device for pig feed, achieving zoned mixing, precise liquid inlet control, deep kneading and blending, and simultaneous wall scraping to prevent clogging, solving the problems of uneven mixing, clumping, and wall adhesion in traditional methods, and improving pre-treatment efficiency and quality.
