Hygiene and food safety of raw materials and end products are vital in the grain and feed

milling industry. Millers take great care to ensure processes meet all legislative and food safety requirements. At the same time, consumers expect food to be safe and are increasingly taking an interest in how their food is produced.

Cutting corners in the area of food safety can have a serious impact on business. Grain and feed products in mills are at risk of being contaminated by foreign material, insects, microbes and vertebrate pests. In addition to high hygiene standards, effective sanitisa-

tion reduces the risk of fine organic dusts accumulating on ledges and crevices, which could result in damage from a fire or dust explosion.

Food and site safety concerns, cou-pled with high costs for energy, water and wastewater treatment are motivating the requirement for hygiene systems that do not employ chemicals and that can save on large amounts of water.

Just as steam power became the fuel that drove the Industrial Revolution – dry steam technology is the latest development playing an increasingly important role in driving trends in 21st century industrial cleaning.

Innovative cleaning using minimal water

Compliance and stringent auditing requirements, combined with pressure of time constraints and cost concerns, means millers are looking for a hygiene system that can save money and work quickly, while being extremely effective.

OspreyDeepclean and its sister manu-facturer, OSPREYFRANK have developed an innovative dry steam technology system which uses less water than traditional clean-ing-in-place (CIP) methods. The new tech-nology meets the challenges of cleaning in environments such as dry food areas, where water systems can’t be used or where there

Tapco nonmetallic buckets have the ability to absorb impactin the elevator leg and “give” or “yield” to bypass an

obstruction. They then return to their original shape and keepon working for you.

Tapco buckets weigh less than their pressed steel counterparts,lack sharp edges and therefore are far safer and easier to handlewhen fitting an elevator.

With 900,000 buckets in 93 sizes stocked throughoutthe world, Tapco has what you want, when you need it!Tapco also maintains over 15 million elevator bolts

is sensitive machinery, motors or anything electric and adversely affected by water.

The technology, which is the first of its kind in the UK, uses a continuous flow heating coil system to heat water to such a high degree that it becomes extremely hot vapour. The emitted dry steam contains minimal moisture and efficient cleaning capa-bility is produced from the steam pressure made on the surface area.

Is all steam cleaning the same?So steam is simply steam? Well actually,

no. Steam can be produced in a range of different grades, each matching dif-ferent industry applications. Picking the cleaning method best suited to your operation depends upon a number of options including the nature of the sur-face to be cleaned and the type of material or residue found on crushing or milling appa-ratus, conveyors and elevator pits and silos.

To date, conventional CIP systems have tended to rely on traditional boiler systems which are only required to heat the water to a maximum of 75 degrees and rely on high water flow and minimal pressure, using a lot of water in the process.

Most food related sites use hot water that comes off the boiler through hoses, using foamers, liquid chemicals and other sanitation agents. They can use between 200-1,000 litres of water per hour to blast a surface clean. They can also have the nega-tive side effect of sending dangerous bacteria airborne, spreading them through the plant without killing them. This ‘wet steam’ system does not use a vapour process.

Benefits of dry steam cleaning Efficient cleaning capacity is produced

from the steam pressure made on the surface to be cleaned and the solvent power of micro drops at a high temperature, with minimal moisture present.

The continuous steam system provides constant steam quality which can be adjusted by volume and dryness. Water flow and heating power can be controlled and adapt-ed by an electronic control system.

The amount of water saved depends upon the flow rate of the water system and the pressure employed, but it can save up to 90 percent of water used. OspreyDeepclean’s dry steam technology will typically use between 10-30 litres of water per hour, whereas a conventional system will use between 200-1,000 litres per hour.

Conventional cleaning leaves the risk of potentially dangerous residues contaminating food and raw materials. Then you also have the issue of getting into difficult spaces, such as tight crevices in storage areas or complex shaped equipment.

Dry steam sanitises surfaces, penetrating cracks, crevices and other hard-to-reach areas where manual and traditional cleaning methods, which mainly rely on potentially hazardous chemicals, fail to achieve the required standards.

As well as being applicable to a wide range of work settings, steam can be used to undertake innumerable cleaning tasks. The system can be used on feeding, mixing and blending vessels, machinery, conveyor belts, rollers, pipelines and also general floor areas, storage spaces and much more. As it is applied to the surface, dry steam leaves very little residue and can almost touch dry, especially when compared

to any other clean-ing method.

No additional ingredients are required in the steam to improve cleaning power, as efficient cleaning capacity is produced from the steam pressure made on the surface to be cleaned and the solvent power of micro drops at a high temperature, with minimal moisture present. However, where specific tasks or loca-tions demand it, ingredients can be added to improve the solidifica-tion of specific substances, for instance within liquid fat appli-cation devices which could congeal with-out the use of additional ingre-dients.

Dry steam machines for different applications

The tech-nology Osprey Deepclean has developed is available in a range of dry steam machines for different applications, based on many years’ experi-ence of creating bespoke steam solutions. This

includes the fully auditable dry steam belt sanitation unit (BSU) which cleans conveyor belts to allergen level, saving up to 3 million litres of water per annum.

The organisation has also developed a central steam system for food production and packaging areas. This is much like a central vacuum, which facilitates cleaning by simply plugging the steam hoses into central steam pipes without the need for handling cleaning machines. The sophisti-

cated equipment can be used for the cleaning of heavy parts and for plastic parts cleaning. The machines start from a 3kW single phase unit and

reach up to 144kW units avail-able in electric, oil or

gas heated coils.

This fully integrated system permits the whole cleaning process to become auditable using sophisticated PC software.

TrainingModern milling machinery is more effi-

cient and faster than ever and is one of

the key investments a company makes. Given the significant sums of money for new machinery and the damage defective products can do, it pays to ensure staff are trained and confident to operating necessary equipment.

Any new sanitation process will require

training with regards to correct usage. The new dry steam technology can be adjusted by volume and dryness to provide a constant steam quality, which can be eas-ily managed and adapted by an electronic control system.

Osprey Deepclean’s technology is avail-able in a range of dry steam machines for different applications. Training is required, so the various accessories can be used effectively to safely remove micro-organisms and bacteria.

Due to the ease of use, industrial steam cleaners translate to labour savings as well. Running costs are reduced because the steam can reach the most inaccessible spots, avoiding repeated dismantling during main-tenance and upkeep operations, which can halve time taken.

This new boiler free technology is at the forefront of water saving science. Energy, water, and waste costs are kept to a minimum, reducing operating costs and overheads and therefore increasing turnover and profit. Thanks to its sanitis-ing properties, environmental edge and extreme versatility for all settings and cleaning tasks, dry steam cleaning is most definitely here to stay.
