Krettek Separation horizontal peeler centrifuge: More Process-Equipment than dewatering device. Six step Course of Excellence, STEP 3 Counter Current washing
In Step 2 we showed you the exclusive possibilities of Extractions
Separation ProCent® Turbo-series is not only best in class peeler centrifuge for solids-liquids separation: The unique Krettek Backflushing Rotor as the key-element in a complete system offers much more than just centrifugal filtration of finest particles with maximum results at minimum effort.
The special design and various options allow complete process-steps inside the equipment, without additional external vessels, components, … such as:

Today’s topic: Counter current washing:
Counter current washing inside a peeler centrifuge is a feature, only possible in Krettek backflushing rotor centrifuges.
Wherever a solid product suspended in slurry needs not only mother liquids-removal but also maximum efficient washing, the Krettek-Technology provides the best-in-class solution.
The unbeaten high g-forces in combination with the wide choice of filter media generates in first step the maximum possible dewatering.
In the second step a washing liquid is fed to the machine from backflushing feeding. Since at the same time the filtrate skimmer device is in home position, the cake can be cross flow washed with the washing liquids for a freely adjustable contact time, while keeping the g-force at an useful level.
Where necessary the liquids can also be feed continuously via backflushing-pipe and skimmed of by overflow skimming device. Again, the freely adjustable g-force gives the possibility of continuously overflow skimming washing agent.
At the end, the dry spinning at market maximum speed results in driest possible and best washed solids.
Since all those steps are set once and controlled automatically from PLC the system can be freely optimized for each individual washing-system.
