MULTIPLE VERSIONS OF DEHUMIDIFIER SILO SYSTEMS TO KEEP BULK POWDERS DRY AND SILOS EFFICIENT

SILO MOISTURE PROBLEMS:


BULK POWDERS CAN ABSORB MOISTURE FROM THE ENVIRONMENT. HIGH RELATIVE HUMIDITY AND DEW POINTS CAN NOT ONLY BE A FRUSTRATING NUISANCE FOR STORING AND UNLOADING YOUR BULK SOLIDS, BUT IT CAN ALSO CONTRIBUTE TO MAJOR DOWN TIME AND MANY EXTRA MAN HOURS WHEN IT OCCURS. WE GENERALLY SEE CLUMPING, RAT HOLING, AND SLUGGISH FLOW OF FLOUR, SUGAR, DEXTROSE AND UREA, TO NAME A FEW, DURING HIGH HUMIDITY MONTHS THAT ALSO HAVE WEATHER CONDITIONS WHERE THE DEW POINT AND THE OUTSIDE TEMPERATURES ARE CLOSE TO EACH OTHER. CONDENSATION FROM HUMID AIR ENTERS STORAGE SILOS VIA THE PNEUMATICALLY CONVEYED AIR AND ALSO FROM AMBIENT OUTSIDE AIR ENTERING THROUGH YOUR BIN VENT DUST COLLECTOR FILTER. THE HUMID AIR CONDENSES ON THE INTERIOR SIDE WALLS OF THE VERTICAL EXPOSED SILO WALLS AND THEN DRIPS DOWN AND AGGLOMERATES YOUR PRODUCT CAN STICK TO SILO HOPPER WALL. MOLD, CORROSION AND DOWNTIME ARE THE RESULT.


THE FOLLOWING ARE TYPICAL HYGROSCOPIC BULK SOLIDS THAT ATTRACT MOISTURE:


• AMMONIUM SULFATE
• BAKING POWDER
• CALCIUM PHOSPHATE
• CAUSTIC SODA
• COFFEE
• CONCRETE
• CORN SUGAR
• DEXTROSE
• EPSOM SALT
• FLOUR
• GELATIN
• GYPSUM
• LIME
• PLASTIC PELLET RESIN
• POTASSIUM CHLORIDE
• SALT
• STARCH
• UREA


SILO MOISTURE SOLUTIONS


SILO BLANKETING SYSTEM WITH DEHUMIDIFIED COOLED AIR

 

BLANKETING THE SILO WITH DESICCANT DRY DEHUMIDIFIED AIR WHEN THE SILO IS AT REST CAN CONTROL THE OUTDOOR MOISTURE FROM ENTERING INTO THE SILO. THE DRY BLANKETING AIR CONSTANTLY KEEPS A SMALL POSITIVE PRESSURE ON THE TOP OF THE SILO, IN THE VOID SPACE, DRIVING ANY MOISTURE OUT THROUGH THE BIN VENT DUST COLLECTOR. SILO MOISTURE CONTROL WILL KEEP POWDERS, GRANULAR AND PELLET BULK SOLIDS FROM LUMPING, CLUMPING AND MOVING IN A FIRST IN FIRST OUT MASS FLOW. WE HAVE UNITS TO SUIT YOUR CONSUMPTION NEEDS, FOR ONE SILO TO MULTIPLE SILOS.


SILO HOPPER DEHUMIDIFIED COOLED AIR AERATION FLUIDIZER

 

INJECTING DRY DEHUMIDIFIED COOL AIR INTO THE CONE HOPPER OF A SILO CAN PROMOTE CONSISTENT PRODUCT FLOW OUT OF SILO WITH BULK SOLID PRODUCTS THAT ARE HYGROSCOPIC AND TEND TO HAVE SLUGGISH FLOW WHEN MOISTURE IS PRESENT. OUR SKID MOUNTED DEHUMIDIFIER/AIR-TO-AIR HEAT EXCHANGER/ PRESSURE BLOWER PACKAGE IS DESIGNED TO CONTROL MOISTURE BY INTRODUCING PRESSURED DRY COOLED AIR INTO THE HOPPER. AIR FLUIDIZERS, AERATION BIN DISC, SOLIMAR PADS ARE POSITIONED ON THE SILO CONE AT THE STORAGE HOPPER DISCHARGE TO PROMOTE CONSISTENT FREE FLOWING PRODUCT OUT. DRY AIR PERCOLATES UP THROUGH THE POWDER, WHICH WILL REDUCE MOISTURE CONTENT IN THE PRODUCT WHEN AT REST. FLUIDIZATION ALSO PROMOTES FLOW.


BULK TRUCK UNLOADING WITH DRY COOLED AIR AND SILO BLANKETING SYSTEM


BULK TRUCK UNLOADING WITH DRY COOLED AIR AND BLANKETING SYSTEM USING OUR SKID MOUNTED DEHUMIDIFIER/AIR-TO-AIR HEAT EXCHANGER/ PRESSURE BLOWER PACKAGE IS DESIGNED TO BYPASS USING AMBIENT HUMID AIR TO CONVEY YOUR PRODUCT. WE CONDITION THE PNEUMATIC CONVEYING PRESSURED AIR TO CONVEY OUT OF YOUR SUBCONTRACTED BULK TRUCK. BULK TRUCK DRIVERS BYPASS THERE PTO BLOWER AND CONNECT TO YOUR COMPRESSED AIR. THIS ALLOWS FOR MANAGING THE AMOUNT OF MOISTURE THAT IS WITHIN THE POWDER OR GRANULAR PRODUCT TO NOT INCREASING ONCE THE PRODUCT IS DRIVEN ONTO YOUR SITE. YOU MAY NOT BE ABLE TO CONTROL THE AMOUNT OF MOISTURE IN THE PRODUCT BEFORE IT IS DELIVERED, BUT OUR SYSTEM WILL CONTROL IT AFTER IT ARRIVES. BY CONVEYING WITH COOL AIR FROM OUR HEAT EXCHANGER, THIS ELIMINATES THE TYPICALLY HOT AIR FROM THE TRUCK BLOWER. HOT PNEUMATIC CONVEYING AIR COMING IN CONTACT WITH YOUR BULK SOLID DRIVES MOISTURE OUT OF EACH SMALL PARTICLE, MOVING THE MOISTURE TO THE EXTERIOR OF THE PARTICLE. THIS MOISTURE IS A PROMINENT REASON FOR AGGLOMERATION AND PRODUCT STICKING TO THE WALL OF YOUR SILO. CHILLERS HAVE ALSO BEEN SKID MOUNTED TO DROP CONVEYING TEMPERATURES BELOW AMBIENT. ONCE THE BULK TRUCK UNLOADING PROCESS IS COMPLETE, THE SYSTEM CAN BE SWITCHED TO A DRY AIR SILO BLANKETING SYSTEM.


PNEUMATIC CONVEYING SYSTEM WITH DEHUMIDIFIED COOLED AIR


PNEUMATIC CONVEYING SYSTEM WITH DEHUMIDIFIED COOLED AIR FOR SUGAR, FLOUR AND OTHER BULK SOLIDS CAN REDUCE PRODUCTION DOWN TIME AND MAINTENANCE OVERTIME HOURS BY KEEPING PRODUCT FROM STICKING AND AGGLOMERATING OF PNEUMATIC CONVEYING ELBOWS. DRY COMPRESSED COOLED CONVEYING IS A PROVEN WAY TO KEEP STICKY BULK SOLIDS CONSISTENTLY MOVING TO PROCESS AREA. WHEN RELATIVE ENVIRONMENTAL HUMIDITY IS HIGH, THAT DAMP CONVEYING AIR IS ALLOWED TO INCREASE THE MOISTURE CONTENT OF YOUR PRODUCT. THE HIGH MOISTURE CONTENT CAN CREATE SLUGGISH FLOW OUT OF DAY BINS AND HOPPERS, SLOWING DOWN YOUR PRODUCTION.
