Description

Technical Field

[0001] The utility model relates to the field of sugar making cleaning equipment, in particular to a raw sugar evaporation cleaning system. Background Art

[0002] In the existing raw sugar evaporation and cleaning system, the high-pressure pump cleaning water pressure can only be maintained at a maximum of about 80MPa for a long time. During manual cleaning, due to safety considerations, the maximum pressure is only 65Mpa. The cleaning pressure is insufficient. After a round of cleaning, there is still a lot of scale residue on the heater and evaporator, and the descaling rate is low. In addition, in order to ensure the balance of the pressing volume and production during the crushing season, the tank is stopped for cleaning for a limited time and cannot be repeatedly cleaned. The incomplete cleaning and residue of scale cause the heat transfer efficiency of the heater and evaporator to decrease, increase the consumption of heating steam, increase production energy consumption, and thus increase production costs. The cleaning pressure of the high-pressure pump in the existing raw sugar evaporation and cleaning system can no longer meet the cleaning needs. Therefore, a raw sugar evaporation and cleaning system is now needed. Utility Model Content
