Food Processor Chooses Sinclair for Special Parboil Conveyors
A major food processor recently awarded B. W. Sinclair Inc. the contract for a pair of special processing screw conveyors to convey, mix, and “parboil” wild rice.
The tubular units feature 36” dia BWSI LongSpan™ rotors with reduced pitch and mixing paddles to retard transfer and promote mixing. The rotors are designed to provide several minutes of retention time to expose the material to low-pressure saturated steam.
The steam is introduced via a series of multiple steam nozzles, each fitted with flexible tubing to allow thermal expansion. The fittings are eccentrically positioned to concentrate the steam per the client’s requirements. A series of condensate collection ports are mounted on the lower centerline to collect liquids and drain them off to a central takeoff. Each port is individually controllable to provide maximum process flexibility.
Custom features that add to the material handling and processing benefits include:
Cinchseal™ silicone elastomer purged gland seals with thermal expansion capability
Dodge SAF-XT™ spherical roller bearing pillow blocks for rotor support
BWSI Expansion-Pedestal Bearing Mount to allow unequal thermal expansion
Rectangular inspection ports fitted with polycarbonate view windows
Multiple instrument connection ports for customer’s designation
Integral support stanchions
Sealed cleanout and access door on discharge spout featuring tubular “poke port” to clear downstream blockage
High efficiency Dodge Quantis™ gearmotor with roller chain primary drive for slow speed operation
Inverter-rated Reliance Electric® motor for adjustment of retention time
All Type 304-L-SS construction
Fine-mesh screens mounted at all steam inlets and condensate drains
