From Artisan Industries, Inc.
Caravan Ingredients, a leading supplier of food emulsifiers, was using vertical wiped-film evaporators to recover monoglyceride. The process required recycle during startup to achieve product purity, yield was marginal, and frequent shutdown for mechanical repair was raising operating costs. Artisan's engineers designed a multi-stage falling-film evaporator/stripper that vacuum strips virtually all of the glycerine from the product. This stream is then directed to a molecular still for monoglyceride separation, and the high-purity glycerol is recycled.
