Kjell Johansson

Title: Kjell Johansson: Innovator in Starch and Cellulose Solutions

Introduction

Kjell Johansson is a notable inventor based in Molnlycke, Sweden. He has made significant contributions to the field of starch and cellulose solutions, holding a total of 2 patents. His innovative methods have the potential to impact various industries, particularly in paper production.

Latest Patents

Johansson's latest patents include a dissolving method for preparing a starch solution. In this method, particles containing starch are mixed with cold water and subjected to shear forces, breaking up any agglomerates formed. Each individual particle is wetted, and the mixture is heated to at least about 60 degrees Celsius, maintaining the heated state until the viscosity maximum of the solution has passed. This process ensures that the wetting and heating occur before reaching an unacceptable viscosity for handling. Additionally, he has developed a process for producing cellulose fiber-containing products. This involves using a suspension of cellulose fibers and optional fillers, to which anionic inorganic particles and a cationic carbohydrate polymer containing aluminum are added. High cationized starch with a degree of substitution of at least 0.07 is especially suitable for this process.
