Central Wash Pump System

Saving energy and providing increased efficiency for food preparation area cleaning

Cleaning the food preparation area in a factory environment is a problem requiring an innovative solution. The use of a high pressure washer system is sometimes not ideal because of the potential for spreading bacteria in airborne particles and the aerosol effect.
This has meant that central wash pump system pressures less than 20 Bar may be used which, although often effective, can lead to the need for more manual cleaning and the use of more aggressive chemicals to remove protein build up etc.

Food process cleaning – the problem

There are now pressures on the management of food factories not only to comply with the high hygiene standards now required but also to control costs and maximise energy efficiency and minimise waste. A central wash pump system should be efficient for its electrical pumping system, its oil or gas water heating and economic in its use of water and subsequent waste disposal. These factors must all be considered without compromising the cleaning standards.

Central washdown system – the solution

B&G bespoke central wash pump systems are designed for cost-effective, efficient and responsible cleaning and can achieve a variety of pressure levels to suit the factory manager’s requirements, from one system.

Over recent years cleaning pressures have risen to allow a reduction in the water flow from each gun. In low-risk areas medium pressures of 40 to 100 bar are common. In high-risk areas lower pressures are common.

Water usage can be optimised by providing the correct pressure for the cleaning task. Electrical energy can be optimised by the use of the central wash multi-pump concept. If only one or two operators use a wash system during the production shift but then say 12 operators are required to clean the factory before the next day, a multi-pump with say 30 litres/minute pumps provides the ideal energy efficiency. This can be achieved with a six pump machine whereby two operators share a pump, or even a twelve pump unit depending on the ideal flow per operator.

B& G has developed a computer controlled wash-down system for larger requirements which uses two of its standard six pump assemblies connected to the same ring main. The system switches on just the number of pumps required depending on how many operators are using the system at the same time, and also ensures that pumps receive equal usage over time. This creates an energy efficient system which uses on average 5.5Kw of electrical power maximum for one high pressure gun. This design would absorb less power for lower pressures.

A Central Wash Pump System using a medium pressure pump set has now been introduced, using a seal-less pump system. This uses 30 litres/min pumps capable of a maximum pressure of 70 Bar. A single pump assembly is available for smaller producers as well as assemblies up to six pumps.

Coupled with efficient satellite foam/sanitiser connection points and a well designed ring main, B&G Cleaning Systems can provide an efficient, operator friendly, turn-key project. We have a wealth of experience in food preparation cleaning and so can offer outstanding advice and information.
