Abstract: A method for removing impurities from shredded plastic uses a device having a first and second cleaning disc with a first and second cleaning surface respectively. The cleaning surfaces lie opposite each other and border a cleaning gap between each other. The cleaning discs are rotated and liquid is fed into the cleaning gap. Shredded plastic is fed between the cleaning discs and conveyed through the cleaning gap, and the shredded plastic is processed abrasively by the cleaning surfaces. The temperature difference of the liquid guided through the cleaning gap during entry into the cleaning gap and the temperature of the liquid as it exits the cleaning gap and/or at least one parameter characterizing this temperature difference is measured. The distance between the cleaning surfaces is set such that the measured temperature difference and/or the at least one parameter characterizing this temperature difference achieve a setpoint value.

Abstract: A multi-chamber conveyor type dishwasher uses a heat recovery unit (HRU) to heat water for a final rinse chamber during a preheat and/or dishwashing phase. The HRU heats water supplied by a low temperature water source using the dishwasher's hot vapor exhaust. An input supply of water for a downstream booster heater is varied based on a sensed temperature of the HRU's output water. If the temperature is acceptable, the HRU supplies input water to the booster heater for the rinse chamber. When the temperature drops below a threshold, the controller temporarily bypasses the HRU and supplies water to the booster heater from a high temperature water source. The HRU may be primed during a preheat phase using water from the high temperature water source. An amount of fan force used to pull the hot exhaust vapors through the HRU may vary based on the status of the dishwasher.
