Achieve repeatable reactions with this one-step solution

| By Mary Page Bailey and Gerald Ondrey

This company’s Continuous Hybrid Reactor (CHR; photo) has been designed to facilitate safe, efficient, repeatable chemical reactions. The CHR features a proprietary design that develops a deep vacuum to promote a high level of control over heat-transfer rate, residence time, mixing intensity and other reaction conditions. The CHR performs heating, cooling, mixing, degassing and other processes in a single step, automatically transforming liquids into powders or high-viscosity slurries, and powders or pellets into high-viscosity slurries or pastes. Suitable for processing elastomers, adhesives, sealants and other temperature- or oxygen-sensitive materials, the CHR feeds primary liquid, slurry or melted solid reactants, catalysts and other reagents through an injection port in the barrel. The integrated heating and mixing action drives the reaction during retention times of up to 1 h, or longer as needed. Consistent product quality is assured while any vapors, volatiles or particulate matter are eliminated, reduced or safely filtered and reused or removed. — Readco Kurimoto, LLC, York, Pa.
