[0049] The specific use process is as follows: during the potato mash conveying process, the cooked potatoes enter the first shell 3 from the feed hopper 2, the controller controls the first motor 12 to start, the cooked potatoes are squeezed into mashed potatoes by the two first screw push rods in the first shell 3 and conveyed to the second shell, the controller controls the second motor 46 to start, the density of the mashed potatoes is squeezed uniformly by the second screw push rod, so as to achieve the stability of quantitative conveying, and the mashed potatoes are conveyed to the mashed potato conveying pipe until the mashed potatoes are conveyed to the mashed potato extrusion pipe 41, the mashed potatoes can be evenly conveyed outward, and the second rotating shaft 29 has different rotation speeds. The amount of mashed potatoes conveyed per unit time is known. When the rotation speed of the second rotating shaft 29 is constant, when it is calculated that the mashed potatoes conveyed reaches the required amount, the controller controls the piston rod of the cylinder 44 to drive the extrusion port switch shaft 45 to move downward, close the outlet of the mashed potato extrusion tube 41, and control the first motor 12 and the second motor 46 to be closed at the same time; after a certain period of time, the controller controls the piston rod of the cylinder 44 to drive the extrusion port switch shaft 45 to move upward, open the outlet of the mashed potato extrusion tube 41, and control the first motor 12 and the second motor 46 to start, so that they continue to convey the mashed potatoes.

[0050] In this embodiment, a timing switch method is adopted, and the piston rod of the cylinder 44 drives the extrusion port switch shaft 45 to rise and fall to realize quantitative delivery of mashed potatoes. After the mashed potatoes have been delivered for a certain period of time, the quality of the delivered mashed potatoes meets the requirements, and the extrusion port switch shaft 45 is lowered by the piston rod of the cylinder 44 to block the outlet of the mashed potato extrusion tube 41. After a certain period of time and when the dough machine completes the dough kneading task, the extrusion port switch shaft 45 is raised by the piston rod of the cylinder 44 to open the outlet of the mashed potato extrusion tube 41 and resume delivery.
