The number of feed ports 351 can be any number, including but not limited to two as shown, and can be, for example, one, three, or others. In an embodiment where the number of feed ports 351 is plural, the plural feed ports 351 may be the same or different. Likewise, the number of ports 352 may be any number, including but not limited to two as shown, such as one, three, or others. In embodiments where number of ports 352 is multiple, the multiple ports 352 may be the same or different.

When the valve core 300 is at the material stopping position, the material discharging channel 350 of the valve core 300 can be stopped. Thus, the rice in the storage bin 800 cannot flow out through the discharging channel 350. The manner in which the feed channel 350 terminates can be varied, such as the inlet 351, the outlet 352, and/or any location intermediate the inlet 351 and the outlet 352. When the valve core 300 is at the blanking position, the blanking channel 350 can be conducted. In this way, the rice in the storage bin 800 can flow out through the discharging passage 350. Therefore, whether the rice in the storage bin 800 flows out or not can be controlled by moving the valve member 300 between the cut-off position and the discharging position.

For example, when the valve core 300 is in the material stop position, a sealing ring 340 may be disposed between the valve core 300 and the sidewall of the blanking opening 810.

Wherein, when the valve core 300 is at the material stopping position, the valve seat 200 can cover the feed inlet 351 and/or the discharge outlet 352. The valve seat 200 may expose the inlet 351 and the outlet 352 when the valve cartridge 300 is in the blanking position. At this time, the feeding hole 351 may communicate with the inside of the storage chamber 800, and the discharging hole 352 may communicate with the outside of the storage chamber 800. The rice in the storage bin 800 can pass through the feeding hole 351 to enter the discharging channel 350, and then flow out through the discharging hole 352.

Illustratively, the feed opening 351 of the blanking channel 350 may be located on a side of the valve cartridge 300. The discharge hole 352 of the discharging channel 350 may be located on the bottom surface of the valve cartridge 300. Wherein, when the valve core 300 is at the material cutting position, the valve seat 200 can cover the feeding hole 351. When the valve cartridge 300 is in the blanking position, the valve seat 200 may expose the inlet 351 and the outlet 352. At this time, the feeding hole 351 may communicate with the inside of the storage chamber 800, and the discharging hole 352 may communicate with the outside of the storage chamber 800. The rice in the storage bin 800 can pass through the feeding hole 351 to enter the discharging channel 350, and then flow out through the discharging hole 352. With this arrangement, the valve assembly 100 is simple in structure and low in manufacturing cost.

The storage compartment 800 may also be provided with an air inlet 950 and an air outlet 920.

Therefore, the sealing performance of the storage bin 800 is better, and the storage effect of the rice is better. The production process of the food material supply device 10 is simplified, and the production efficiency is improved. And as the sealant such as silica gel is cancelled, the safety of the rice is higher, and the health of the user is guaranteed.
