Visually detectable standard parts are made of blue plastic.
The blue color makes them especially visible to the human eye and, perhaps more importantly, to optical monitoring systems. Especially in milk and meat products, but also in most other areas of food production, blue colors are rarely encountered and therefore stand out well.
Complete standard parts or only pieces of them that mistakenly end up in the food production can then be easily and reliably detected. In addition, contaminants and residues of food on standard parts and operating elements are also easier to identify thanks to the color contrast.
All visually detectable plastic standard parts are made of FDA compliant plastic granulate as per FDA CFR.21 and EU 10/2011 and can therefore be used safely in contact with food and in pharmaceutical production.
