Pressure leaf filter principle and operation details

Pressure leaf filter principle of the operation






PRESSURE LEAF FILTER 


THE PRESSURE LEAF FILTER  CHANNELS  ARE  UTILIZED IN EDIBLE OIL REFINERY FOR THE FILTRATION OF VEGETABLE OILS IN DIFFERENT HANDLING STAGES LIKE PRESS OIL CLEANING, WINTERIZATION, BLANCHING AND BEFORE DEODORIZATION OF EDIBLE OIL.

PRESSURE LEAF OPERATION PRINCIPLE 


1. CAKE BLOATING of PRESSURE LEAF FILTERS


THE OPERATION OF THE CHANNEL DEPENDS ON THE GUIDELINE OF SPENT EARTH FILTRATION.

THE CHANNEL COMPONENTS CHANNEL LEAFS COMPRISE OF A SYSTEM WHICH IN A FEW LAYERS IS SECURED WITH FINE-FIT METAL NET. A FEW CHANNEL SHEETS ARE ORGANIZED IN THE CHANNEL BOX ON THE RELEASE PIPE. THE CHANNEL BOX IS FILLED UNDER WEIGHT WITH SHADY OIL. THE OIL COURSES THROUGH THE SURFACE OF THE CHANNEL COMPONENTS INSIDE THE SYSTEM AND LEAVES BY MEANS OF THE RELEASE PIPE. THE CAKE AND THE CHANNEL HELP ARE GATHERED AT THE SURFACE OF THE CHANNEL SHEETS. IN THE EVENT THAT AN ADEQUATELY THICK LAYER OF SIFTED CAKE HAS FRAMED ON THE SURFACE OF THE CHANNEL SHEETS THE SEPARATED OIL CAN BE REROUTED INTO THE UNADULTERATED OIL TANK. THIS STAGE IS CALLED CAKE SWELLING. AMID CAKE SWELLING THE OIL IS DRIVEN ONCE AGAIN INTO THE OVERCAST OIL TANK. THIS PROCEDURE CAN BE QUICKENED BY THE UTILIZATION OF CHANNEL HELPS.


2. PRESSURE LEAF FILTRATION PROCESS


ADEQUATE DEVELOPMENT OF CAKE AT THE CHANNEL COMPONENTS ENDS UP NOTICEABLY EVIDENT WITH THE EXPANSION OF WEIGHT AND THIS CAN BE OUTWARDLY WATCHED. THE SPAN OF THE FILTRATION STAGE AND THE AMOUNT OF THE ACQUIRED OIL ARE DICTATED BY A FEW MEASURED FACTORS:

OIL TEMPERATURE, WHICH IS BASIC FOR THE KINEMATIC THICKNESS,

EXTENT OF CAKE IN THE OVERCAST OIL,

MOLECULE ESTIMATE CIRCULATION IN THE CAKE - AN ESTEEM WHICH IS FIRMLY RELIANT ON THE WORKING METHOD OF THE OIL PRESS

THE SORT AND AMOUNT OF THE CHANNEL HELPS UTILIZED SAWDUST, CELLULOSE

3. RECOVERY OF PRESSURE LEAF FILTER


IN THIS STAGE THE UPSIDES OF THE WEIGHT LEAF CHANNEL END UP PLAINLY CLEAR IN CONTRAST WITH THE CHAMBER CHANNEL PRESSES. THIS METHODOLOGY, AND ALONG THESE LINES THE WHOLE PROCEDURE, CAN BE TOTALLY ROBOTIZED. ALSO, THE METAL FIBER CHANNELS HAVE A MORE DRAWN OUT LIFETIME THAN THE CHANNEL FABRICS OF THE CHAMBER CHANNEL PRESS.

ON THE OFF CHANCE THAT A SPECIFIC WEIGHT IS ACHIEVED, THE SUPPLY OF OVERCAST OIL HAS INTERFERED THE OVERCAST OIL FROM THE FULL CHANNEL IS RELEASED INTO THE SHADY OIL TANK. ALONG THESE LINES THE STICKY CAKE ON THE CHANNEL COMPONENTS ARE DRIED BY PRESSURIZED AIR. AMID THIS STAGE, AIR DEPLETED THROUGH THE RELEASE PIPE IS SLICK AND SHOULD BE FIRST DRIVEN THROUGH AN OIL SEPARATOR.

THE DRY CHANNEL CAKE CAN BE EFFECTIVELY DISCHARGED FROM THE CHANNEL COMPONENTS BY THE PNEUMATIC SHAKER. THE CHANNEL CAKE FROM THE CHANNEL IS RELEASED THROUGH A PNEUMATIC FOLD. THE FOLD IS AGAIN SHUT, THE VALVES COME BACK TO THE POSITIONS FOR CAKE SWELLING, AND ANOTHER CHANNEL CYCLE CAN START.
