We have new machinery installed that will produce a product that is for pet food.
in the process of production the mixed product is formed then passes through a cooling system to harden the product, this product is packed and naturally softens in the warehouse in ambient temperatures.
We are BRC accredited and this new machine will be in the scope of our next audit my query is that they operators currently record temperature of the cooling system every hour and document. the limit of the cooler has a small tolerance of 6°c.
The problem is that the cooler temperatures changed regularly so that the end product comes out hardened, leaving the temperature at a set point may work one day/per production run but then not the next leaving a soft end product.
The recording is quite different to the tolerance and I have been asked weather we need to have a tolerance to aim for at all seeing as the final product being hardened is the sole aim of the cooler.
The thoughts I have are if there is no target then recording seems to be futile.
If the tolerance is set to incorporate all that different temperatures that it has worked at then it will be a large margin 15°c
Any advice on this would be appreciated.
to note: the analytics of the end product are the same weather it is softer or hardened the sole purpose is to have a hardened product which makes the product not fall to pieces when being packed.
