Use of Pump Rotors in Poultry and Meat Processing Industry

October 23, 2018

In a progressive cavity pump, a mechanism that's using a helical rotor, food industry mediums are being processed by the chrome-plated component. The near-solid mix contains soft tissue, which means there's raw meat moving in discrete pockets around and through the screw pump rotor. Sanitary by design, the equipment endures when stringy, possibly acidic, probably oily meats are conveyed. One thing's for sure, every part of the pump is food-hygiene certified.

Poultry and Meat Processing

By "processing," we could be referring to one of a dozen possible food industry applications. Meat is being conveyed to a destination, where it'll be worked upon further by another station. It could also be a waste recovery line, a section of the food preparation factory that removes offal and other waste products. Gently pumping the edible fare, meat or poultry, onwards, the pump rotor is once again made of a super-toughened alloy, which in turn is double coated in chrome, nickel or some other hardened metal. Differently, at least this time around, the fluid is loaded with unique material challenges, as delivered by a stringy meat/bone mix.

Sanitary-Certified Conveyance Mechanisms

Food grade stainless steel works at the heart of the machine. No bacterial colonies can gain purchase when this polished metal is used for a pump rotor. Also, again from a food-safe vantage point, that screw coating never flakes, never discharges metallic contaminants, and it certainly never uses jointed parts, which are known germ harbouring sites. No, the outer substrate coating of a poultry and meat processing rotor has to be smooth, entirely featureless, and easy to clean. This means the rotor alloy has to resist corrosion, as caused by acid and oil-loaded soft tissue, and it has to be tough enough to stand firm when a bone edge abrades the alloy. Beyond those features, however, the rotor and stator combo must be easy to clean.

Pumping offal and waste away, the maceration of this foul mix doesn't create an issue. It's when a consumable meat and poultry runnel experiences this effect that problems occur. A figurative red light flashes on and off above the process line. After all, those discrete pockets of meat-filled soft tissue require gentle handling. Fortunately, or should we say, by design, the rotor moves slowly and deliberately, not like a regular pump, which would chew the meat up until it was an unidentifiable stream, full of meat slush. Remember now, the process leader wants the chunks of meat and poultry segments to arrive at their final destination unbruised and fresh, even when it's being processed by an energetic pump.
