Title: David Roschli: Innovator in Flavoring Technology
Introduction
David Roschli is a notable inventor based in Pfungen, Switzerland. He has made significant contributions to the field of flavoring technology, holding a total of 3 patents. His work focuses on innovative apparatuses and methods for preparing flavoring agents.
Latest Patents
One of Roschli's latest patents is an "Apparatus for preparation of a flavoring agent." This apparatus integrates a mixing unit for combining powder-form and liquid ingredients into a paste-like mixture. It also features a kneading and heating unit for plasticizing the mixture, a heating tube for reacting the plasticized mixture, and an extrusion die that opens into a chamber maintained under reduced pressure by a pump. The pressure for propelling the plasticized mixture can be generated by a positive pump or by closely spaced flights of a screw extruder positioned before the heating tube.
Another significant patent is related to the "Preparation of a seasoning." In this process, a protein hydrolysate and at least one reducing sugar are mixed with water to create a paste-like mixture. This mixture is then kneaded and heated to plasticize it. The plasticized mixture is propelled through an extrusion unit under a pressure ranging from 1 bar to 100 bar and heated at temperatures between 80°C and 140°C for a duration sufficient to effect the Maillard reaction. The reacted mixture is extruded into a chamber under reduced pressure for drying and cooling, ultimately providing the flavorant.
