Open the vacuum tube and suck the liquid raw materials into the stirring chamber of the main chamber, and add the solid raw materials through the top feed port;

The control cylinder (38) adjusts the opening of the control rod (39) to accurately control the flow of gel through the discharging connecting pipe (42) to the discharging port (43). The discharging cylinder (40) drives the discharging push block (41) to push periodically and quantitatively inject it into the packaging tube.
