PUMPING SYSTEM AND METHOD FOR A BEVERAGE PRODUCTION APPARATUS |
摘要 |
The present invention presents a pumping system (1) with a preheated reservoir (2), a main pump (4) for pumping a preheated liquid (3) from the reservoir (2), and pressurizing means (5) for pressurizing the reservoir (2). Preferably, the pressurizing means set an absolute pressure of 0.5 to 1 bar in the reservoir (2). The liquid (3) in the reservoir (2) can be heated up to 90° C. or more. The present invention achieves a nearly complete suppression of the phenomenon of cavitation at the main pump entrance, and thus achieves an increased pumping performance at elevated liquid temperatures. |
