Ultrasonic Drying of Biodegradable Molded Recycled Paper Fiber-Based 3D ProductsCoated and Impregnated with Biodegradable Pulp Additives and Barrier Dispersions. February 18, 2024 Heat Technologies, Inc. (Atlanta) GA has recently completed a series of ultrasonic drying tests (by its Spectra HE Ultra TM drying system) aimed at establishing optimized operating parameters for single serving containers manufactured from recycled paper fiber suitable for food products with contained moisture. Two groups of identical shape and weight containers were tested. One group was impregnated and non-impregnated with biodegradable additives, and the second one was not. Both groups were coated with equal quantities of the Reef biodegradable coatings. Both the additive and the coating were manufactured by Cellucomp (UK) and independenlty tested by the QC laboratory of Danish Technological Institute (Denmark). Results of the tests (COB1800, MTR-WTR), best coat weights to obtain positive results, operating temperatures,production throughput,as well as general dimensions, energy consumption are prsented in the attached article.
