CIP pumps provide hygienic solutions for Russian food plant

05 August 2017

Watson-Marlow Fluid Technology Group (WMFTG) has supplied its Bredel CIP (clean-in-place) pumps to a sauce and condiments manufacturing plant in Russia. 

Replacing pumps that were proving difficult to clean and maintain, Bredel CIP 50 models are being used to pump products such as cheese sauce, tomato ketchup and mayonnaise.
The pumps are available with the option of externally-operated retracting shoes that release the hose so that the line is open and unobstructed for cleaning.Pumps featuring this option are used at the Russian plant, with a food-approved hose and food grade lubricant, both supplied by WMFTG, while stainless steel sanitary connectors include DIN, ASA and JIS types.
 Hygiene and sterility are crucial at the plant where, depending on the production plan, CIP is often scheduled daily. The process takes place at full velocity using food industry standard cleaning agents such as Tarmo (1.0%) and ET (0.3-0.5%).
The new pumps have been installed on two filling lines to transfer cheese sauce, which is heated to 75°C. Here, the sauce needs to be pumped quickly from the hoppers to the filling lineat flow rates of up to 7000 l/hr. If the sauce cooled in the pump hose or in the transfer lines, it would solidify, which would cause huge cleaning issues because hot water and stronger cleaning agents would be needed to break down the starch and fats.
Ketchup and mayonnaise
Elsewhere on site, Bredel CIP pumps transfer ketchup through 20m long pipework with 7m delivery. The pumps dose ketchup with a viscosity of 50,000 cP (at 30-40°C) from the hoppers to a line that fills plastic single serving sachets for fast food outlets. 
Aside from ease-of-cleaning, there were other important factors to consider when selecting a pump, including the shear thinning of these thixotropic sauces. Other factors included the avoidance of air entrainment which could lead the sachets to burst upon filling, and the need for sterility. 

The success of the pumps on the site have resulted in a planned upgrade at another site in Russia, where Bredel pump technology will again be deployed.
