Keeping your food scales clean

feee

Scales used in the food industry often come into direct contact with the product. As such, liquid may accumulate on the scales and food particles may stick to them. Besides affecting the accuracy of weight readings, these also bring about the risk of microbial contamination.

It is extremely important, therefore, to ensure adequate cleaning of these food scales.

An effective and efficient cleaning is easier to achieve when you have the right equipment, so when you are looking to purchase, go for scales that are designed to prevent bacterial growth both on product and non-product contact surfaces.

Construction materials should be compatible with the product and environment, and should not have any water collection points. Every part of the equipment, even those that do not come into direct contact with food, should be easy to clean, maintain and inspect.

How to clean food scales

  • Firstly, turn off the balance display before cleaning.
  • Wipe the weighing pan and drip tray with a wet tissue daily if possible.
  • Non-food contact surfaces like the housing and terminal should also be cleaned.
  • The weighing pan, drip tray and draft shield panels can be placed in the dishwasher and washed with mild detergent if necessary.
  • Remember to wipe dirt away from the hole at the centre of the balance, and do not allow any substance to enter the internal parts.
  • Frequently disinfecting surfaces will ensure the elimination of bacteria.
  • Do a final rinse to remove all traces of soil, detergents and disinfection substances, so that none will get in contact with food.
  • Reassemble the balance, switch it on and make sure it is working correctly.

What you should not do

  • Do not apply too much pressure on the balance pan, as this can damage the internal mechanism.
  • Turning the scales upside down and shaking it is not a good way to remove residue and will only cause damage.
  • Do not use cleaning fluids that are harsh like ethanol, as it will react with agar, salts and other common ingredients.
  • Do not leave salts on the scales, as this can corrode the scales.
