Sinusoidal Pump Beats Lobe Pump For Condensed Milk Handling

UK-based Kerry Ingredients & Flavours faced a challenge in finding a pump that could handle the demanding viscosity and flow properties of condensed milk being used in a new line of toffee sauce at its plant in Tenbury Wells, UK. After considering both a rotary lobe pump and a sinusoidal pump, Kerry selected the MasoSine SPS 2.5 sine pump from Watson-Marlow Fluid Technology Group (WMFTG). The pump’s innovative sinusoidal rotor overcame the limitations of a the rotary lobe pump to produce powerful suction with low shear, low pulsation and gentle handling that worked perfectly for the company’s new sauce.

New product poses challenges

The Tenbury Well plant is the ingredients and flavors arm of Kerry Foods, part of Kerry Group Plc, and everything produced at the 300+ employee factory is shipped to other plants. The factory specializes in wet and sweet products, including soft jams (called ‘yogfruit’), chocolate sauces for cakes, pie fillings, and commercial jams for doughnuts.

Kerry is one of the leading and most technologically advanced manufacturers and innovators of application-specific food ingredients and flavors in the world. However, when the plant wanted to introduce a new toffee sauce to its 10 production lines, the company was faced with the challenge of pumping condensed milk. Initially, volumes were small, typically 1-2 batches at a time, and Kerry used manual labor to perform the necessary operations. However, demand grew rapidly and it was soon apparent that they needed a more automated pumping solution.
