Abstract: A multi-surface scraped surface heat exchanger for heating or cooling of liquids or slurries having a series of three or more concentric tubes that provide four or more heat transfer surfaces, three of which are independently temperature and flow controllable. Slurry products are cooled or heated across all of the surfaces in line or in parallel. Scrapers are mounted on a rotor assembly and are magnetically or spring tensioned to increase surface engagement and may be contoured to enhance folding and mixing of product.

Abstract: A method for the rapid continuous mashing and cooking of grains, legume pulses, corn kernels, seeds or the like, as a stage in the production of a food product, said method including the steps of: introducing said grains, legume pulses, corn kernels or the like into a continuous throughput high-shear mixing/cooking device in which said materials are heated at a pressure of up to 40 Bar and to a temperature of between 100° C. and 200° C. and are then expelled from said device and cooled to a target temperature for storage or further processing.

Abstract: The modular, angular direct steam cooker of this invention provides an agitated continuous cooker apparatus which is heated with direct steam injection. The body of the cooker is designed in sections to allow increasing the capacity of the apparatus by adding sections of injectors to the length of the cooker. The food product is pumped into one end of the cooker and elevated to discharge out of the upper end of the cooker thus preventing air or steam vapor from forming pockets in the product as it progresses through the cooker from inlet to outlet. The slope of the cooking chamber can be increased or decreased to improve mixing and reduce compaction of different food products.
