  • 120-year-old creamery specifies MasoSine SPS2 from Watson-Marlow
  • High volume, low pressure application on new clotted cream line
  • Demo pump supplied initially to help customer meet pre-Christmas rush

A MasoSine SPS2 sanitary process pump supplied by Watson-Marlow Pumps Group has helped Rodda’s, a Cornish creamery with a history dating back over 120 years, to implement a new clotted cream line. Installed at the end of 2012 in time for the Christmas rush, the product benefits from the sine pump’s high flow yet gentle handling characteristics.

History in the making
In 1890, Eliza Jane Rodda started making clotted cream in her farmhouse kitchen in the heart of Cornwall. It was an immediate hit and before long she was ‘exporting’ it to London.

Over 120 years on, Redruth-based Rodda’s is still producing their famous Cornish Clotted Cream the same way, by gently baking rich local cream until it’s silky smooth with a characteristic golden crust , which is why it’s been awarded Protected Designation of Origin (PDO) status, along with other well known foods such as Champagne and Parma ham.

In terms of manufacturing operations, prestigious brands demand suitably befitting production equipment. Tasked with installing a new cream line, Engineering Supervisor at Rodda’s, Paul Johnson, knew the pump for the job.

“Clearly we are keen to avoid any product damage or compromise to product integrity,” he states. “Using a centrifugal pump, for example, would effectively turn the cream into butter. We already knew about the MasoSine sinusoidal pumps available from Watson-Marlow and we have found the pump compliments our new filling assembly.

Gentle handling
The MasoSine positive displacement pump features an exclusive sinusoidal rotor that overcomes the limitations of conventional rotary lobe pumps to produce powerful suction with low shear, low pulsation and gentle handling.

“This isn’t a high pressure application, rather a high volume one,” says Mr Johnson. “Essentially the pump transfers liquid cream from a tank to a hopper on a new production line. The machine then fills our range of pots.”

For this application, the MasoSine SPS series is an ideal match, offering gentle handing that minimises the potential for aeration, yet with the high flow (up to 100,000 litre/hr) required to match throughput demand at Rodda’s. It takes six pints of milk to make a 227g pot of Cornish Clotted Cream, and each day Rodda’s make enough clotted cream to outweigh eight rugby teams.

Powerful suction
High flow is achieved using the pump’s sine-wave-shaped rotor, which creates four moving chambers that convey the duty fluid from the inlet port to the discharge port. The scraper gate prevents any fluid passing back from the discharge side to the suction side of the pump. Rodda’s operate the MasoSine SPS in conjunction with a variable speed drive and ultrasonic level sensors in the hopper. If the level is high, the pump runs slower, and vice versa.

“At the time, because of the need to meet pre-Christmas demand, Watson-Marlow helped us out with the immediate delivery of a demo pump. It was a manual version of the pump we have now, and it got us through this busy period nonetheless.”

This was good news indeed for the company’s customer base, many of whom refuse to take anything less than Rodda’s PDO-certified Cornish Clotted Cream.

About us

Watson-Marlow Fluid Technology Group (WMFTG) peristaltic tube and hose pumps meet requirements including: value for money; low cost of ownership; reliability and ease of maintenance to the food and beverage, chemical, pharmaceutical, mining and many other industries.

We demonstrate how pumps deliver significant process efficiencies over the lifetime of the equipment. Whether performing flavouring addition in food processing, chemical metering in water treatment or mineral recovery, we have a solution which can cut pump downtime and reduce costs through higher accuracy metering and transfer. WMFTG has dedicated application engineers available to help customers make the right pump and tubing choice from a range providing microlitres per minute to 80 cubic metres per hour flow rates.

The only part of the pump to come into contact with the product is the tube or hose. This means there are no seals or valves that can wear or fail. Replacing the tube or hose can be performed quickly and safely. Peristaltic pump benefits include:

Total fluid containment with no seals No ancillaries Handle viscous and abrasive slurries and sludge Self-priming capability Dry running without damage to the pump In addition to their range of positive displacement pumps, Watson-Marlow Fluid Technology Group has added PTFE-lined chemical and industrial hoses to their range. Aflex hoses are reinforced to withstand the most severe conditions and use.
