1. Acid detergents
Detergents with a pH value below 4 are potentially damaging to the
equipment. They are not suitable for daily cleaning and their use should
be restricted to once a month at most , followed by a thorough rinsing
process with clean water.
2. Neutral detergents
Use preferably neutral detergents with a pH value of 7.
2. Alkaline detergents
Alkaline detergents with a pH value between 7 and 12 are normally
suited to everyday cleaning.
However if any of these detergents are mixed with a Chlorine or strong oxidizing agent (used to
break down proteins and some vegetable staining such as carrot) then special care must be taken
to use not only the correct concentration but also to thoroughly rinse it off.
Typical concentrations should not exceed 2% and must be rinsed off within the specified time,
typically 10 to 15 minutes not more than 20 to 30 minutes and should never be permitted to dry
on the surface.
Since most detergents are sprayed on as a gel or foam, it is important to thoroughly rinse it off,
this also applies to the disinfectant, which if left to dry on a surface, will increase the effect of the
oxidizing agent in the detergent.
1.3 Cleaning Process
For most applications it will be perfectly acceptable to perform a wipe down of the system with a wet
or damp cloth. If the application is not messy (i.e boxed product), then a wipe down will be adequate
for the system. If however the product is naturally messy then a wash down will be required. A wash
down is described as follows:
The wash down process can be broken down into steps:
1. Removal of product and coarse dirt.
2. Application of detergent.
3. Period to allow detergent to become effective.
4. Washing down and final rinsing.
Please consult the manufacturer’s instructions for detergent use and pH level, and for any
recommended protective clothing.
1. Removal of product and coarse dirt.
The hinged lid on top of the system can first be opened and all product
spillage and coarse dirt removed from on and around the transport conveyors,
especially the weigh conveyor. Low air pressure may be used for the removal
of loose dirt or product from on and under the transport conveyors.
2. Application of detergent
Apply the detergent either manually or under low pressure. Use brushes where application is manual to
aid in the freeing of stubborn dirt, but do not use any abrasive tools, which may damage belts or rollers.
The Checkweigher wide belt or multiple tape conveyors are designed for quick and easy release and
removal. This will allow for more thorough cleaning (or maintenance) of each.
