Technical Field
[0001] The utility model belongs to the technical field of stirring equipment, and in particular relates to a parallel-axis vacuum refrigeration stirring machine. Background Art
[0002] There are many ways to eat meat products. In addition to cutting the meat into pieces and processing them, you can also grind the meat into ham, meatballs, meat fillings and other meat products. At the same time, a variety of meat products with different flavors are added to the meat, which greatly enriches our food variety. In the meat processing process, a food mixer is used to mix the meat products.
[0003] The traditional mixer mixes and stirs the chopped meat and various complementary foods in the mixer cavity to make them mixed together for subsequent processing. The traditional mixer uses paddles or sticks of various shapes to stir the meat while the cavity rotates. The patent publication number CN201620391138.3 discloses a meat mixer, including a chassis and a stirring shaft driven to rotate by the chassis, a stirring box rotatably connected to the stirring shaft, a stirring rod is arranged on the stirring shaft in the stirring box, and a controller for controlling the periodic forward and reverse rotation of the stirring shaft is also arranged in the chassis. The length of the stirring box is 1-1.2 meters, and a plurality of stirring rods are arranged, and the plurality of stirring rods are evenly distributed along the circumferential direction of the stirring shaft. The stirring rods are all provided with stirring blades with an angle of 30-35° with the stirring shaft. The meat mixer has a good stirring effect. However, when the meat mixer is mixing meat, the viscosity of the meat causes excessive resistance when the mixing shaft rotates, and the transmission rigidity between the mixing shaft and the drive motor is too large, resulting in the mixing shaft breaking. In addition, a large amount of heat is generated during the mixing of the meat, which leads to a decrease in the activity and quality of the meat. Utility Model Content
