Granular material feeder for foam forming
By using a combination of rotary airlock valves and pressure supply pipelines in the foam forming system, the problem of air entrainment during the supply of superabsorbent materials was solved, achieving continuous material supply and foam stability, and improving the operating efficiency of the headbox and the quality of the foam.

Abstract
A process and system for adding particulate material to a foam stream in a headbox. The particulate material feeder includes: a first feed hopper capable of being filled with particulate material; a second feed hopper; and a rotary airlock valve disposed between the first and second feed hoppers. The rotary airlock valve is configured to transfer superabsorbent material from the first feed hopper to the second feed hopper. A pressure supply line is connected to the rotary airlock valve and configured to allow air to flow into and / or out of the rotary airlock valve.
