Title: Innovations by Andreas Lehnberger in Crystallization Technology

Introduction

Andreas Lehnberger is a notable inventor based in Braunschweig, Germany. He has made significant contributions to the field of crystallization technology, holding a total of 3 patents. His work focuses on improving methods and devices for obtaining crystals from solutions, particularly in the sugar industry.

Latest Patents

Lehnberger's latest patents include a cooling crystallizer and a sugar crystallization method. The cooling crystallizer is designed for saccharose magma in a vertically oriented container. It features an upper inlet for supplying magma and a lower outlet for discharging it. The invention incorporates multiple cooling blocks that are spaced vertically, allowing a heat carrier fluid to flow through them. These cooling blocks are connected to a heat exchanger to dissipate heat from the magma. Additionally, multiple cooling blocks are combined to form a cooling packet, with each packet designed as a separate cooling circuit with its own heat exchanger.

The second patent details a method for obtaining crystals from a mother solution. This method involves feeding the mother solution into a crystallization device, where supersaturation is achieved through temperature control. Seed crystals are added at a specific seeding point, and these crystals grow as nuclei through continuous closed-loop process control. The method also includes sensors that detect data to determine the position of the limit for the formation of secondary nuclei, which is crucial for effective crystallization.
