Example 3

On the basis of the

embodiment

1 or 2, the following optimization is also made, and the extrusion back plate 1 is provided with an opening and closing device 7 for opening and closing an outlet of the wet grain bag.

Specifically, if this embodiment is based on the solution of embodiment 2, the opening and closing device 7 is disposed on the side of the extrusion backplate 1 away from the depressed groove 5. The position is more convenient to operate the outlet position of the wet grain bag.

The outlet of the wet grain bag is opened and closed by the opening and closing device 7, so that the outflow of soup can be reduced or avoided, air and bacteria can be isolated, and the safety problem caused by deterioration of wet grains can be avoided.

Specifically, the opening and closing device 7 may adopt at least any one of the following schemes:

1. the opening and closing device 7 comprises an opening and closing gate 71, a spring 72 connected to the opening and closing gate 71 and used for providing reset elastic force, and an electromagnet 73 used for electrifying and attracting the opening and closing gate 71; the electromagnet 73 attracts the opening and closing gate 71 by magnetic force to open or close the outlet of the wet grain bag.
