We use cleaning brushes and wet cloths to clean conveyor belts that carry sugary and powdery candy. But we find that they aren't very effective. Using a large volume of water isn't a good idea as the powder gets all sticky and hardens in a short amount of time. Using compressed air is a no go as there is potential for dust explosions. Any ideas on how we can improve effectiveness of our cleaning?

Hot hot water is the best thing to get sugar, most syrups, honey...If it's your dry side and you don't want to bring in water (water will up your risk with the bagging side of sugars, I'd stay away from it for routine cleaning if possible) then you will want dust collectors for your combustible dust and soft bristle brushes for your line/conveyers. Make sure they are correctly controlled (for example not food contact color coded and not floor color coded..) and kept to whatever standards you have for cleaning utensils.

If you CAN'T or don't want to go dust collectors, you will need to add deep cleaning of the entire room to whatever level keeps your dust buildup below combustible dust standard for sugar (it's been like 12 years, but I want to say around 1/3 inch? LOOK IT UP THOUGH).

 

Edit: Why are the brushes you use now not effective? Is the room especially humid?

Thanks, TimG. The problem we have is that the amount of sugar and dust that accumulates over a week (cleaning is done at the end of the week) is significant, and the brushes we have work only so well in getting them off considering that so much of it is sticky dust.

When production ends, the air conditioning system is turned off and the room does gets very muggy.

What type of conveyor are you using?  Is changing those out a possibility?

Steam?

Easiest solutions based on this would be either brushing just the conveyers down at the end of each shift, or keeping the room climate controlled in between end of week cleanings. It sounds like your muggy nights are melting your crystal buildup, which is causing your issue.

In my bagging plant we ran that air all week and the powder stayed dry enough that daily brush downs were sufficient to keep buildup down on the bagging line. We had short lines from the hopper through the metal detector to palletizing, so it was fairly easy in our case to brush down several times a shift.

These are plastic Intralox belts.

Got it. Do you think it is worth exploring the possibility of using detergents?

 Is it worth switching out? that belt style is best for full wet washdown
