WASHSYSTEMS In the food production and processing environment your cleaning objective is to produce surfaces free from debris and food residues which may harbour bacteria.Hugh Crane systems provide: . improved cleaning efficiency • simplicity of operation • ease of maintenance • high quality components • hygienically designed cabinets minimising bacteria harbouring • low water usage
Pressures and Temperatures AOSS-3 wall mounted outlet point with simple product selection.
On the following pages we address the different pressure and flow requirements for a wide variety of environments. Inadequate pressure can often result in poor cleaning results. Excessive pressure will cause aerosols and splashing which increases the risk of both cross contamination and equipment damage. Typically, washing temperatures over 65˚C are commonly used in meat production; however heat can have a detrimental effect on some chemicals and can even fix some proteins such as egg. Hugh Crane engineers are here to advise on the appropriate pressures, temperatures, flow rate and chemical application equipment needed for your processing requirement. Please call us on 01493 750072.

LOW PRESSURE Typically 0 - 500psi, 0 - 35 bar Low pressure wash systems offer several advantages, and can be very effective when used in the correct environment. Lower pressure reduces the risks of: • Aerosols • Splash-back • Cross contamination • Water ingress • Personal injury

Another consideration is that to produce good quality foam at pressures below 500 psi / 35 bar requires air injection from an outside source. This need not be a problem as long as compressed air is available, as a stabilised foam air injection system can be installed, which could be wall or trolley mounted giving the versatility you require.
Au t o
These points make a more user friendly system, however due to the lower pressure a higher flow rate is normally required, which can lead to increased heating and running overheads. This is usually offset by lower maintenance costs.

MEDIUM PRESSURE Typically 500-1000 psi / 35-70 bar Systems operating at these pressures are becoming the most popular choice in the food processing environment. A well designed system with the correct flow rate can be just as effective as systems with higher pressures.
Medium pressure offers many of the benefits of low-pressure: • Low aerosols • Reduced cross contamination • Reduced water ingress • Reduced personal injury risk Unlike low pressure systems it is possible to create reasonable quality foam without the aid of compressed air by using dynamic lances.
Wo r kin g
Our design team have developed a range of advanced pump systems with fully modulating return valves, which unlike most systems, do not waste energy by continuing to pump a percentage of the flow back to the tank when demand is increased. These systems offer the user a choice of pressure and flow so that more delicate areas can be cleaned with confidence thereby making interim cleaning easier.

o ur future
All systems are supported by on site maintenance programs and extensive staff training which makes them very attractive and cost effective packages.
HIGH PRESSURE Typically 1,000 psi / 70 bar plus In environments such as abattoirs, poultry sheds and farm buildings high pressure systems are ideal. The pressure can be combined with chemicals and heat to give a very powerful cleaning effect.
Advantages: • Easy removal of stubborn greasy soiling • Detergents can be easily foamed • Flexibility
Elements to consider: • Equipment damage • Aerosols • Health and safety
Flexibility: A well developed high pressure system will provide the benefit of multi pressure outlets to ensure you have the flexibility for changing production areas as you add new machinery and vary production methods.
1000 Ba r
Centralised multi-pump systems with selectable flow and pressure are worth considering as you can add pumps as your demand increases. You may require a stand-alone diesel or petrol powered unit or perhaps a small single lance electric model. Whatever your requirements you can rest assured we will be able to guide you to the correct solution.

FINAL APPLICATION The final application method is a very crucial part of the cleaning operation. Having selected a quality chemical product, your costs and bug counts will depend largely upon using the correct concentrations. To ensure the correct dilution at all times we at Hugh Crane have developed a range of high-quality hygienically designed outlet stations and equipment to complement any wash system. They range from simple bucket fillers or valves with snap on injectors to specialised mixing units with recording systems to accurately monitor chemical and water usage for ease of documentation. They also feature easy selection of wash, detergent and disinfecting functions, saving valuable time as well as reducing equipment costs.

DOSINGMETHODS The need for precise dosing of chemical products is a critical part of the production process. To fulfil this requirement different methods can be employed, including:
Proportional Dosing The main flow of water through the unit drives a piston, directly linked to this is a second smaller piston that lifts the chemical and injects it into the water stream. By adjusting the stroke of this second piston, the dosing rate will change.
Timed Dosing This method can be used to effectively dose tanks or vessels. An electronic timer and pump unit is programmed to issue initial and top-up doses.
Conductivity Dosing Some chemicals affect the electrical conductivity of water; this can be used to accurately maintain the chemical content. By inserting a probe into the vessel to be dosed, conductivity levels are monitored and chemical is automatically added as and when required.
Venturi Dosing The water flow is fed through a venturi, which pulls the chemical into the stream via an orifice, the size of which determines the injection rate.

STORAGE & DECANTING With tightening COSHH and Health & Safety regulations safe storage and decanting of chemical products is very important.
Considerations • • • • •
Bunding Temperature Materials Decanting Drench showers
If chemicals are to be stored in transportable containers, bunded flooring, secure storage containers or sump pallets can be used. A wide range of trolleys incorporating accurate decant systems for the direct dosing of fryers, vessels, tray and rack wash machines are available from stock or custom manufactured.
Where bulk storage is required we offer a range of plastic or stainless steel bunded tanks with options of fully sealed insulation and immersion heaters to prevent freezing. Accurate air or electric powered decanting systems can distribute chemical to production areas to accurately dose cooking vessels etc. Drench showers with eye flooding facility are also available to be installed alongside your chemical storage facility and in key areas within production.
