Why Blue Plasters? Because it gives high visibility amongst food where the colour does not naturally occur. Why Metal Detectable Plasters? To detect contamination in cans and foil packaging as well as cartons, trays etc. Sources of Contamination
Raw materials – wire in fabric
Personal effects – hair clips, coins, paper clips
Maintenance – swarf following repairs
In-Plant processing – metal slivers from knives
Steroplast Blue Plasters ARE:
Metal Detectable as non-ferrous. (The Steroplast Blue has an aluminium strip located behind the lint).
Steroplast Blue Plasters ARE NOT:
Metal Detectable as ferrous (no ferrous component in the Steroplast Blue.
X Ray Detectable (Steroplast Blues do not contain tungsten)
Detectable when used in conjunction with food packed into aluminium foil trays.
The Detectability of Steroplast Blue Plasters
Sensitivity of the Metal Detector. Ideal setting should be to 2.5mm non-ferrous
Metal Detectors respond to: a) Amplitude Detection Rejects when the signal exceeds a pre-determined level. Ideal for longer metal pieces OR b) Narrow zone/zero crossover Rejects when any signal is produced Disadvantage is that when several different size pieces pass almost together the signal from the largest piece fools the detector, which may miss the following smaller piece. Factors affecting sensitivity i) Type of metal Iron is easily detected, stainless steel is not ii) Shape of metal Spheres are easier to detect than thin wire of the same metal – eg 1.5mm dia stainless steel ball equates to 1.6mm wire 8mm long for detection at the same setting. iii) Orientation of metal in product Due to the shape of the magnetic fields in a detector, certain parts of the field are more sensitive compared to others, therefore potential blind spots can occur. iv) Environmental Conditions A detector operating next to a hot oven, freezing tunnels or vibration affect sensitivity. v) Product Dry Products – eg cereals easy to detect metalFresh meat – creates an interference signalPickles – the vinegar creates a false signalTreacle – very dense product high sensitivity required To ensure metal detection at low sensitivities the setting pieces used are placed in the middle of products as well as on the product. Therefore if changing from one type of product to another, the detector settings have to be changed due to the densities of the product.
