New Dupps evaporator plant one of North America's largest.
When West Coast Reduction, Ltd made the decision to build a brand new rendering plant for non-SRM beef products at their Alberta Processing Division location in Calgary, one operating criterion took precedence: the new facility had to be energy efficient.

The solution: an evaporator system that takes advantage of recycled waste heat from other plant systems to dramatically reduce natural gas consumption. It's one of the largest and most advanced evaporator plants for rendering ever built, with a raw material capacity of up to 65,000 lbs. per hour.

The new Dupps hybrid HCPR™ (High Compression Press Release) screw shaft for Pressor® high-pressure screw presses can extract more fat by dramatically lowering residuals in most rendered products.

The patent-pending HCPR design combines high compression with a release/re-compression feature. By compressing material twice, the HCPR releases more residual fat. In the same way that squeezing a household sponge twice releases more moisture, the HCPR shaft can release more fats by eliminating voids in the feed as it travels through the press.

Combined with precision-cut barrel bars, the HCPR shaft can provide up to 25% lower residual fat in pressed crax for most rendered products. Which means that depending upon Pressor capacity, the HCPR shaft can deliver up to 110 lbs. more fat per hour. Download brochure
