PREFACE

This manual includes tables, specifications and procedures necessary to design conveyor line using the following Gates Mectrol Food Grade Belting:

∫ PosiClean® Belting∫ CenterClean™ Belting∫ FlatClean™ Belting

SAFETY POLICY

WARNING! Be Safe! Gates Mectrol belting is reliable when used safely and within Gates Mectrol application recommendations. However, there are specific USES THAT MUST BE AVOIDED due to the risk of serious injury or death. These prohibited misuses include:

Lift Systems

Do not use Gates belts or pulleys in applications that depend solely upon the belt to raise/lower, support or sustain a mass without an independent safety backup system. Gates belt drives systems are not intended for use in applications requiring special “Lift” or “Proof” type chains with minimum tensile strength or certified/test tensile strength requirements.

Braking Systems

Do not use Gates belts or pulleys in applications that depend solely upon the belt to slow or stop a mass or to act as a brake without an independent safety backup system. Gates belt drive systems are not intended to function as a breaking device in “emergency stop” systems.

SPLICING OPTIONSNOTE: Fastener strength ratings are specific to the belt to which they are applied. See Maximum Allowed Tension specifications in belting specifications tables.

∫ Factory Weld – uses a 78 mm (3.1”) or 85 mm (3.3”) long tapered finger and a platen press weld. The shear strength provided by the overlapping tension members provides for the highest maximum allowable belt tension.

∫ Field Weld - The preferred field splice for PosiClean is a split tooth weld. The weld of a straight cut through a tooth is stronger than that of a straight cut between teeth. This is because the weld surface area is larger through the tooth than between the teeth. A second benefit of

and less stress. Preparing belt ends with a straight cut requires only simple tooling and is done easily and quickly. Tapered finger welds can also be used for field welds but require more cumbersome finger punch tooling.

∫ PosiLace™ Fastening Pin – meets low to medium load requirements without welding to achieve the maximum allowable tension of 21 lbs/in. Belt ends are prepared at the factory and the belt is joined by a single pin inserted after the belt is placed in position on the equipment. This “living” fastening solution allows for removal and replacement of the belt as often as desired – without ever having to weld.

∫ Other Mechanical Fasteners - From wire hooks to metal staples, standard conveyor fasteners are available are available for those situations when quick assembly/disassembly is required. Belt ends must be cut properly prior to installing mechanical fasteners to ensure proper pulley mesh.

Belt guiding and tracking ∫ The conveyor frame must be rigid, square and aligned in all planes for the Gates Mectrol food grade

belts to track properly. ∫ PosiClean o PosiClean belts are not self-tracking designs. External guides along the belt edges are

required. Guides can be stationary or rollers. Surfaces on stationary guides that contact the belt should be made of UHMW-PE. Conveyor side rails or frames can serve as stationary guides.

C-6 ∫ FlatClean o V-Guides: See page B-14 for available V-guides and minimum recommended pulley

diameters.Carryway Support

∫ Continuous support rails, parallel to the belt length, made of UHMW-PE or acetal (POM), is the preferred carryway support for PosiClean, CenterClean and FlatClean belts. Gates does not recommend stainless steel support rails.

∫ Joints in support rails: downstream rail should be should be slightly lower than the joining upstream rail or have a beveled end to prevent damage to belt teeth or underside of the belt.

o PosiClean , PC10 and PC20, Figure C-5

o CenterClean, CC40, Figure C-3

FOOD BELT DESIGN MANUAL

GATES MECTROL

BELT SANITATIONGates Mectrol food grade belting is designed to be easy to clean and specifically for Clean-in-Place sanitation procedures. It does not require soaking and immersion to achieve proper sanitation levels. In order to achieve maximum belt life, immersion in chemical solution for sanitation is not recommended.

Recommended Sanitation Procedures

1. Remove large food residues by mechanical means (scraper/brushes etc.)2. Rinse conveyor with hot water to further remove food soils, preferably belt is not under tension

∫ Approximately 60°C/140°F (avoid boiling water for safety and belt life) ∫ NOTE: high water pressure may atomize water and make pathogens airborne

3. Apply cleaning detergent to the conveyor and belt ∫ Usually alkaline/surfactant combination

4. Rinse conveyor with hot water (approximately 60°C/140°F) ∫ NOTE: high water pressure may atomize water and make pathogens airborne

5. Apply sanitizer (germicide) to reduce microorganisms to safe level6. Rinse with water if necessary

∫ Dependent on sanitizer toxicity level

Common Sanitizing Chemicals∫ Sodium hyperchlorite (bleach) is a common sanitizer used in the food processing industry. It

attacks all families of thermoplastic polyurethane to some degree. In order to maximize belt life, the time that the bleach solution resides on the belt should be minimized and the solution should be at room temperature. Gates Mectrol belt jackets are made of polyether based thermoplastic polyurethane (TPU). This family of TPUs are more resistant to attack by the typical chemicals used in the food industry including sodium hypochlorite than the commonly used polyester based thermoplastic polyurethanes.

o Guidelines for Use of Sodium Hypochlorite on Gates Mectrol Food Grade Belting

o Maximum concentration level: 2,000 ppm of available chlorine

NOTE: If concentration levels exceed 200 ppm of available chlorine, the belt must be rinsed with potable water after the application of the sodium hypochlorite per US Government regulations 21 CFR Part 178 .

o Maximum residence time on belt for contraction levels exceeding 200 ppm : 20 minutes

o Maximum solution temperature: 90°F (32°C)

∫ Sodium hydroxide (caustic soda) is found in many cleaning/sanitizing solutions. Sodium hydroxide

∫ Quaternary ammonium compound (Quats) is a common sanitizer in the food industry. This sanitizer does not attack Gates Mectrol’s food belting.

longevity and food contact / environmental temperature. Gates Mectrol food grade belting does not require soaking and immersion to achieve proper sanitation levels. Immersion in chemical solution for sanitation is not recommended for our food grade belting in order to achieve maximum belt life. Our belting is designed for Clean-In-Place sanitation.
