Abstract
A spray booth for producing cellulose insulation and a system for producing cellulose insulation uses the spray booth. Input cellulose material is fiberized and cellulose dust is removed from the fiberized cellulose material. The fiberized cellulose material is directed to a spray booth where cellulose fibers and matrices of cellulose fibers are sprayed with a liquid fire-retardant chemical to produce wetted cellulose fiber. The wetted cellulose fiber is dried in a dryer to produce cellulose insulation.
