Abstract
A method for removing deposits inside a section in a food processing system is provided. The method comprises introducing a cleaning liquid into the section, inducing boiling of the cleaning liquid by adjusting a pressure and/or a temperature inside the section to a first pressure value and/or a first temperature value, thereby forming bubbles in the cleaning liquid, imploding the bubbles by adjusting the pressure and/or temperature to a second pressure value and/or a second temperature value, thereby forming a mechanical impact on the deposits such that these are released from the section, and transferring the deposits being released by the cleaning liquid out from the section.
Claims15
A method for removing deposits inside a section in a food processing system, said method comprising
- introducing a cleaning liquid into the section,
- inducing boiling of the cleaning liquid by adjusting a pressure and/or a temperature inside the section to a first pressure value and/or a first temperature value, thereby forming bubbles in the cleaning liquid,
- imploding the bubbles by adjusting the pressure and/or temperature to a second pressure value and/or a second temperature value, thereby forming a mechanical impact on the deposits such that these are released from the section,
- transferring the deposits being released by the cleaning liquid out from the section.
A food processing system comprising
- a product inlet pipe arranged to transport a food product during a production phase and a cleaning liquid during a cleaning phase,
- a heating unit arranged to heat the food product during a production phase and the cleaning liquid during a cleaning phase,
- a section arranged downstream the heating unit and configured to hold the food product during the production phase and the cleaning liquid during the cleaning phase,
- a counter-pressure valve arranged downstream the section,
- wherein the counter-pressure valve is configured to adjust a pressure inside the section,
- a control unit configured to, during the cleaning phase, induce boiling of the cleaning liquid by adjusting a pressure and/or a temperature inside the section thereby forming bubbles in the cleaning liquid, and to implode the bubbles by adjusting the pressure and/or temperature, thereby forming a mechanical impact on deposits in the section such that these are released.
