BULK STARCH SILO
131,000 LB. CAPACITY BULK STARCH SILO (12’ X 42’) (3.28)
This item consists of a silo, dust collector, cone aeration, and other equipment to store pearl starch. It includes:
- (1) Heavy-duty 12’ diameter x 42’ eave height silo to store approximately 131,000 lbs. of starch weighing 40 lbs. per cubic foot. The silo is fully skirted with welded construction and has the following features:
- (1) Access ladder with fallback and landing to meet OSHA requirements
- (1) Top railing with toe board.
- (1) Exterior surfaces painted with white enamel
- (1) Interior surfaces lined with non-FDA epoxy.
- (1) Explosion relief deck (weak seam design).
- (1) Bolted cone access man-way
- (1) Skirt access door.
- (1) 60º cone design.
- (1) Pressure vacuum relief valve.
- (1) Top access man-way.
- (1) High level (overfill) probe with audible alarm.
- (1) Low level probe with indication and alarm at starch room.
- (1) Truck fill station, complete with required fittings, 4” O.D. aluminum tubing, elbows and couplings.
- (1) Silo grounding package with clamp to ground delivery truck during the unloading process.
- (16) Aeration pads with manifold, pressure reducer, and control valve to aerate the silo using the plant’s compressed air.
- (1) Bin vent with nine pleated filter cartridges (202.5 sq. ft. breathing area), solid-state timer, and solenoids. This bin vent uses reverse blow down for cleaning.
- AUGER (SILO TO MIXER)
This item is used with the new or existing silo to feed pearl starch to the mixer; it includes:
- (1) Lot required transitions.
- (1) 6” O.D. auger housed in 7” O.D. mechanical tubing. The motor is rated “inverter duty”.
- (1) V.F.D. to control auger speed and thus accuracy.
- (1) Pair 6” butterfly valves, each with double-acting pneumatic actuator.
- (1) Set of additional electrical controls housed in the control panel listed earlier.
- 150’ PNEUMATIC BULK STARCH CONVEYING SYSTEM
Two-way, closed loop system designed to convey starch up to 150’ from the silo to the included 1,500 lb. capacity receiving hopper and auger (with V.F.D.) delivery system. It includes:
- (1) Conveying blower equipped with a T.E.F.C. 1,800 RPM motor mounted on a common base with guards, pulleys, belts, and a positive displacement blower.
- (1) Rotary airlock, slidegate, and transitions to meter starch into the conveying line.
- (1) Lot (approximately 350’) of aluminum tubing with 36” radius long sweep bends.
- (1) Lot required 3-bolt compression couplings with ground strip.
- (1) Lot (approximately 30’) of material handling hose with hose shanks and hose clamps as required.
- (1) Set of electrical controls (to be located at the silo skirt) in a dust-tight cabinet. These controls are to be pre-wired to terminal strips, consisting of side operated disconnect, control circuit transformer, selector switches with indicating lights, and starter with line and overload protection for the blowers, rotary airlock, and all other equipment located at the silo.
- (1) 1,500 lb. receiving hopper equipped with one vibrator and one airpad to eliminate hopper bridging, etc.
- (1) Hopper level probe for fill control.
- (1) 6” O.D. auger housed in a 7” O.D. mechanical tubing to feed pearl starch to the mixer. The auger is V.F.D. controlled.
- (1) Pair 6” butterfly valves, each with pneumatic actuator to seal the wet mixing process from the dry bulk starch.
- (1) Set of additional electrical controls to be housed in the starch room control panel.
- SUPER SACK HOPPER (FOR MODIFIED CARRIER STARCH)This item is intended to add dry modified starches in those plants that choose to run a modified carrier. It includes:
- (1) Steel hopper designed to hold pearl starch (approximately 1,500 lbs.). This hopper has been designed for use with a customer supplied crane (jib or gantry) and hoist. It is equipped with a turbine vibrator to prevent bridging.
- (1) Lot required transitions
- (1) Rigid auger with fixed drive
- (1) Pair 6” butterfly valves, each with double-acting pneumatic actuator
- (1) Set of additional electrical controls housed in the control panel listed earlier in this proposal
