Functional Floors for the Meat Industry
By selecting and planning for the correct flooring solution from the word ‘go’, your Abattoir, Butchery or Meat Processing plant is able to spare itself a number of serious headaches later.
In a bid to increase and ensure health safety within the food production sector more stringent standards apply when it comes to clean room design, materials of construction – such as flooring – and factory layout.
Building finishes are set to be emphasised in the new standards, ensuring application of coatings that are easy to clean and are more resistant, suggested solutions include epoxy-floors, polyurethane flooring and becoming increasingly popular is the steel floor option.
Consumers have also become highly sensitive to foreign body complaints or anything that might affect their individual health, calling for a good amount of funds to be invested in food safety equipment and measures, including flooring.
One of the main considerations in selecting a flooring option includes considering the volume and type of traffic that a floor is expected to carry. Meat processing plant managers are compelled to consider skid-resistant floors to ensure personnel safety and potential liability issues by using textured or grit surfaces.
The degree of texture is typically determined by the conditions of operation, frequency of cleaning and maintenance, and presence of oils, greases and other potentially slippery substances.
Environments are often damp or wet, either from cleaning agents or from the inherent exposure to oils and grease. A flexible membrane may be a viable option applied beneath floor coatings where high impact and heavy loads are part of the traffic pattern.
The floor, or subsequent floor coating, must be durable enough to handle vigorous cleaning procedures that typically incorporate the use of very hot water, steam and aggressive cleaning chemicals. Only high-performance floor coatings will withstand such punishing maintenance.
Differing plant areas have differing corrosive conditions, such as dry areas, cold storage rooms, and food production areas. Another deciding factor in floor and coating selection includes application conditions. While not so relevant in new facilities, it is indeed important when updating or refurbishing an existing facility.
Apart from limiting downtime, food processing areas are often damp, sometimes cool or even cold, and sometimes hot – all in a typical day. The selected coating must be able to be installed under any and all of these conditions.
There are specialty coatings that have the ability to cure even under this unusually broad range of conditions.
Urethane modified cementitious flooring systems, for example, can perform in steam heat as well as freezing or below zero temperatures. Some of these systems also offer a rapid return to service which could be critical to plant operations.
A strong driver for food production hygiene standards is the Hazard Analysis Critical Control Point (HACCP) food safety management system. The HACCP principles require that throughout the various processes within a facility, all possible points of risk should be designed out of the system, and where the risk points cannot be excluded altogether, sufficient monitoring and control systems should be put in place to best manage the risk.
Consequently, the meat industry environment calls for smooth, non-porous operating surfaces across a variety of plant areas that promote easy cleaning within a strict cleaning regime. Coatings should be durable enough and thick enough to create a protective barrier to prevent contaminants from permeating the concrete substrate and ensuring a hygienic surface.
Uncoated concrete floors may be perfectly acceptable in warehouses and light industrial areas, but cleanliness and purity are of paramount importance to hygiene and safety requirements, calling for seamless, hygienic floor coating systems.
Selecting the correct type of floor coating is therefore one of the most important product specifications a plant manager is likely to make and each product caters for a number of requirements and are available in several formulations.
Types of floor coating
Epoxies are available in a range of flooring systems including high-solids or 100% solids epoxy flooring products that provide outstanding protection against acids and alkalis. Key benefits include outstanding adhesion; an excellent ability to withstand abrasive cleaning procedures and chemicals; fast curing properties for minimized downtime of the area being treated; and compatibility with textured, anti-slip additives. Additionally, high-solids formulations are low in Volatile Organic Compounds (VOCs).
100 % solids epoxies, on the other hand, are a wise choice for coating floors when a rapid return to service is required. Benefits include having strong bonding characteristics, resistance to thermal and mechanical shock, and the ability to endure frequent cleaning with hot water at high pressure.
In less demanding environments like food packaging, waterborne epoxies are a good fit since these areas don’t have the same high protection demands. In general, though, the use of waterborne epoxies for this industry is limited.
Urethanes are also a popular option in the food industry. Polyurethane coatings are generally supplied in slurry form and, although initially more costly, its service life often outlasts other product categories.
When compared to epoxy and vinyl coatings, urethane cement slurry and mortar systems provide better resistance to thermal cycling, as well as excellent long-lasting performance. They also have a very low odour during application and have a seamless, easy-to-clean surface when dry.
But without a doubt, the most significant benefit of some mortar systems is their quick drying capabilities as plants can be returned to service in a few hours. However, slurries are not recommended for floors that are sloped to drain.
Polyureas prove excellent when the environmental demand is for tough, flexible and impact resistant floors. They provide a seamless and flexible surface that has the ability to withstand temperatures as low as -20°F to 250°F. All polyureas are formulated with no VOCs, have no odour and dry tack free in as little as 45 seconds. Their elasticity makes them ideal for substrates such as concrete, which tends to crack. As an elastomer, these coatings have the ability to stretch and bridge gaps and are not limited by temperature extremes.
