Description

[0001] This application claims priority to Chinese application No. 202323616267.7 filed on December 28, 2023. TECHNICAL FIELD

[0002] The utility model belongs to the field of food processing equipment, especially a meat grinder. BACKGROUND

[0003] The working principle of the meat grinder is to cut the meat by shearing action of the rotating cutter blade and the hole blade on the hole plate, and under the extrusion force of the auger screw, the cut meat is continuously discharged out of the machine. Generally, a meat grinder only uses one auger to process meat, relying on one auger to simultaneously achieve the functions of conveying the meat poured in and forcing the meat to be transported to the cutter for mincing, which increases the pressure of the system. When a large amount of meat is poured into the hopper of the meat grinder at one time, it may cause blockage. Therefore, in actual feeding operations, operators usually adopt the strategy of reducing the amount of single feeding to prevent such blockage problems from occurring. This feeding method is time-consuming and inefficient.

[0004] Chinese patent CN222171118U discloses a double-auger meat grinder, which includes a frame, a feeding cylinder arranged on the frame, and a hopper arranged on the feeding cylinder. A rotating feeding auger is arranged in the feeding cylinder, the bottom of the hopper is connected to the inside of the feeding cylinder, and a stirring part is arranged in the hopper. A feeding screw sleeve is arranged at one end of the feeding cylinder, a fascia removal hole plate cutter is arranged in the feeding screw sleeve, and an auger conveying motor is arranged at the other end of the feeding cylinder to drive the rotating feeding auger to rotate. The rotating feeding auger includes two rotating augers used in cooperation. A stirring motor is further arranged at the bottom of the frame to drive the stirring part to rotate.

[0005] This patent uses the stirring part in the hopper to mix and pre-crush the meat, and then uses the left-rotating feeding auger and the right-rotating feeding auger arranged side by side to cooperate to convey the meat. Although the left-rotating feeding auger and the right-rotating feeding auger are arranged, the two augers are arranged side by side, which is easy to form a meat ball and cause material jamming. In addition, the stirring part is used to mix and pre-crush the meat, which increases the cost and system burden. UTILITY MODEL CONTENTS
