Referring to fig. 1 to 5, according to an embodiment of the present application, a food processor, particularly a pulverizer and a wall breaking machine, is provided.
Referring to fig. 1, the food processing machine in this embodiment includes a base 10, a cup 20, a crushing cutter set 30, a driving assembly 40, a cup cover 50, a vacuum-pumping device 70, and a heating device 60.
Wherein, the bottom of frame 10 is provided with bottom 13, sets up first PCB board 11 and second PCB board 12 on the frame 10, is convenient for control the cooking machine. The cup 20 is detachably mounted on the housing 10 to contain food materials. A crushing blade set 30 is installed in the cup 20 to crush food materials in the cup 20. The driving assembly 40 is mounted on the housing 10 and is in driving connection with the crushing cutter set 30 to drive the crushing cutter set 30 to rotate in the cup body 20 to crush food materials. A cup cover 50 is mounted on the cup body 20 for opening or closing the cup opening. When the food processor in the embodiment works, firstly, the cup body 20 is placed on the machine base 10 under the action of the cup handle 21 arranged on the cup body 20, then food materials are put into the cup body 20, and then the cup body 20 is buckled by the cup cover 50. At this time, the driving assembly 40 can be started to drive the crushing cutter set 30 to rotate through the control action of the first PCB 11 and the second PCB 12 on the base 10, so as to crush the food materials in the cup body 20.
Since a certain amount of air is present in the cup 20, the food material in the cup 20 is easily oxidized. Therefore, the cup cover 50 in this embodiment is provided with a vacuum device 70 for performing vacuum treatment on the cup body 20, and the vacuum device 70 is electrically connected with a control board inside the stand 10 through the coupler 100.
