Video Monitoring System for Brewery Trub Removal

This application note details the implementation of a video monitoring system in a brewery to enhance the trub removal process and prevent cross-contamination of batches. The document outlines the challenges faced during trub removal, particularly the risks associated with incomplete flushing of the whirlpool tank. It describes the brewery's decision to install a video camera on the sight-glass of the whirlpool tank to monitor the process remotely. The note explains the installation steps, including discussions with operations personnel, data collection, and the selection of a suitable camera. It also addresses the environmental challenges that led to initial failures, such as condensation and overheating of the camera. Modifications were made to improve performance, including the use of a hydrophobic sight-glass and an air-cooled housing for the camera. The results demonstrated that the monitoring system effectively identified issues in real-time, leading to improved process efficiency and water savings. The system has been operational for over two years without maintenance issues.
