Method for filter treatment i.e. cleaning, of milk, involves guiding free-flowing medium through bag filter, and guiding medium through another filter bag, where one of filters is cleaned during guiding of medium flow through another filter

摘要

The method involves guiding free-flowing medium through a bag filter (2), and measuring pressure difference between a filter input and a filter output of the filter. The medium flow is switched to another bag filter (3) during reaching of predetermined maximum permissible pressure difference. The medium is guided through the latter filter, and pressure difference between a filter input and filter output of the latter filter is measured. The medium flow is switched back to the former filter, where one of the filters is cleaned during guiding of the medium flow through another filter. An independent claim is also included for a filter device.
