  • Patent number: 11116232
    Abstract: A method for producing a first milk product having a first fat content and a second milk product having a second fat content. The method includes separating raw milk into cream and skim milk, diverting a first part of the cream into a first cream pipe, and a second part of the cream into a second cream pipe, dividing the skim milk in the main skim milk pipe, such that a first part of the skim milk flows into a first skim milk pipe and a second part of the skim milk flows into a second skim milk pipe. Flow rates for the two cream parts and the skim milk parts are determined, and valves are adjusted based on the determined flow rates, such that the milk products are obtained when mixing the cream and skim milk parts.

  • Patent number: 11100630
    Abstract: A method of defect detection in packaging containers for liquid food is disclosed, where packaging containers are produced in a machine. The method comprises capturing image data of the packaging containers, defining image features in the image data representing defects in the packaging containers, associating the image features with different categories of defects, inputting the image features to a machine learning-based model for subsequent detection of categories of defects in packaging containers based on the image features, determining time stamps for the occurrence of defects in said subsequent detection, determining associated production parameters of the packaging containers in the machine for the occurrence of defects based on the time stamps, and correlating said occurrence and category of the defects with said production parameters. A system for defect detection in packaging containers is also disclosed.
