Food Grade Lubricants

METALUB are manufacturers of a full range of food grade lubricants, all having NSF H1, H2, H3 or 3H classification. Lubricants for use within food processing & manufacturing the products must be totally non-toxic and satisfy the regulations for non-food compounds used in food manufacturing and food packaging plants. These strict guidelines mean products are selected based upon their use/classification with either incidental food contact USDA H1 (now NSF H1 class), H2 Class (without risk of food contact) or H3 (direct food contact). Secondly they must perform well as lubricants, often extreme high or low temperatures or aggressive cleaning processes are encountered, all of which can adversely affect the life of the lubricant.

High Temp Chain In Bakery

In bakeries for example, the ovens can reach temperatures in excess of 260C. Conveying components and chain bearings operating in these conditions can often require frequent re-lubrication or cleaning to remove unwanted lubricant residue build up. We can supply everything from hydraulic, gearbox and general lubricating oils to food grade greases for extremes of temperature from –70 C to 260 C. We also have a range of biodegradable products should this be required. Using the correct lubricant in any given application can reduce costs, increase productivity and reduce costly failures whilst also reducing the overall environmental impact.

Lubricant Classification for Food Processing

For food and beverage producers, pharmaceu-ticals manufacturers, and producers of con-tainers used to package food-related products, there’s no more important lubrication issue than the use of what are typically referred to as “food-grade lubricants”. Lubricants intended for use in food production are registered with the National Sanitation Foundation (NSF) as either H1, H2 or H3, de-pending on the intended application and for-mulation. Registration is voluntary and simply requires a review of the product ingredients with a list of compounds known to be “safe” for incidental food contact at low levels. Food grade lubricants for packaging machinery that will contain food or beverages must now be produced on machines and equipment that use approved NSF certified lubricants. Of the three, H1 is by far the most important classification and is typically referred to as a lubricant designated for “incidental food con-tact”. This relates to applications where it is possible for the lubricant to touch the product (food, beverage, pharmaceutical, etc.) in low concen-trations due to leakage or over-lubrication.

Pharmaceutical

The only classifications for registration of a lubricant by the NSF are the following:-
H1 – General – incidental contact H2 – General – no contact H3 – Soluble oils HX-1 – Ingredients for use in H1 Lubricants (incidental contact) HX-2 – Ingredients for use in H2 Lubricants (no contact) HX-3 – Ingredients for use in H3 Lubricants (soluble oils) The 3 H classification is different and can be used for many different food processing sub-stances. It is classified 3H as a release agent for direct food contact. This could be chopping boards, meat slicing blades and mincers to stop the food sticking thereby acting as a lu-bricating film and release material.
