Title: The Innovations of Kari Vanhatalo
Introduction
Kari Vanhatalo is a prominent inventor based in Helsinki, Finland. She has made significant contributions to the field of cellulose processing, holding a total of 10 patents. Her work focuses on innovative methods for producing microcrystalline cellulose and its applications in various industries.
Latest Patents
One of Kari Vanhatalo's latest patents is a process for producing microcrystalline cellulose from fibrous cellulosic material through acid hydrolysis at an MCC plant. This process involves thickening a suspension of cellulosic pulp to form filtrate. The consistency of the thickened suspension is adjusted to 5-40% by adding dilution liquid, and the pH is lowered to 4 or less using acid. The pulp suspension undergoes acid hydrolysis at temperatures of at least 120° C. in a reactor, resulting in a mixture of microcrystalline cellulose and hydrolysate. The mixture is then discharged to lower pressure and temperature to flash the mixture and generate flash steam. Microcrystalline cellulose is separated from the hydrolysate, and the separated cellulose is washed in one or several washing apparatuses. The consistency of the microcrystalline cellulose is further increased by thickening and/or drying for additional processing. Another notable patent involves a lignin-containing microcellulose as an animal feed additive, aimed at improving feed conversion rates for production animals, such as poultry.
