dust control

Is this a hazardous area application where the dust is potentially explosive in certain concentrations and you are trying to limit the possibility of an explosion? What type of dust are you storing?

You have to supply much more information please, we cannot read your mind.

Here you can see where the dust is:

Grass is extremely important to most people's lives, whether they know it or not. For one thing, grass is a major food source all over the world. Rice, corn and oats come from grass plants, for example, and most livestock animals feed primarily on grasses. In some parts of the world, people use grass plants in construction (bamboo is a grass, for example), and wherever it grows, grass plays a vital role in curbing erosion. Grass is also used to make sugar, liquor, bread and plastics, among many other things.

Well, other thoughts... To cool down the air inside the store with a good air conditioner could be an idea, because more dust can be found in hot air then in the cold air. A statue in the middle of the store would do the trick:

Is this dust countable ?

Dust in the air can be measured: some answers are found by searching for "air testing particulate matter"

For methods and equipment for sampling and testing, search "measuring particulate matter"

For ideas to control dust, it would be necessary to know: what is the source of the dust? If dust is produced in a production process, there may be ways of filtering or collecting dust during the process. What type of dust particles?

Basically we are in spices.

So the dust is powder form of spices.

Step 5: Figure out the four steps.

Is the dust caused by the processing (grinding) or during other handling (weighing or measuring) ?

Is dust in the air the main problem, or dust residue that settles on surfaces?

Yes dust cause is processing and grinding and also other handling.

Without knowing what machines are involved, I would suggest that you review the handling procedures. I'm assuming that the grinding is done with a machine that is completely contained (with a lid of some kind closed during the grinding).

The dust problem would be worst if you are pouring the ground spices from the grinder into another container. Also any other handling that involves pouring, which is the worst method for releasing fine particles into the air.

I would experiment with a handling method other than pouring if possible: using a scoop, for example, to transfer the material. There's a technique I use to take ashes out of my furnace. Fill the scoop (or in this case a shovel) by digging into the powder while disturbing the upper layer as little as possible. Let any dust settle for a moment before you move it. To transfer it to a container, slide the material off the scoop, again taking care not to disturb the surface layer on top. That is the best technique to minimize dust escape into the air.

In the case of my ashes, there's a draw from the open flue which conveniently sucks any fine ash particles in the air back into the furnace. There are appliances that can be designed to do this for your spice operation. The dust collector setup for spice grinding might be similar to a "fume hood" type of enclosure, where any disturbed dust is drawn into or kept inside the enclosed area by a fan set into the upper surface of the enclosure. This sort of setup would work for open grinding processes as well.

Otherwise, if it is necessary to pour the powder at some stage of the operation, use a plastic bag around the pouring operation, I mean, bring the bag up tight around the receptacle that's being tipped, so that the whole operation is contained. Let the dust settle completely inside the bag before further handling.

For the dust that you can't avoid, microfibre cloth technology is excellent for general cleanup of dust on surfaces: fine particles cling to the damp microfiber cloth much better than an ordinary cloth or mop.

Dear Artsmith,

what you say its correct. even we want to reduce ash percentage in our product.

Please suggest me something good design of dust collector which i can get easily in India.

What is this microfibre cloth technology?

sandeep,

RE: the dust collector, you should get talk to a suppllier or get professional advice about which model, I cannot help you there. Spice dust is heavier than 'fumes' so I'm not sure what kind of fan or filters you would need. Maybe even a range hood fan would be good enough. I was thinking something along these lines:

RE: microfiber:

This is about the technology: http://en.wikipedia.org/wiki/Microfiber

This is how to find a supplier: Google for : microfiber cleaning cloth wholesale India

You can see in this arrengement they provide air through solenoied valve which get operated every after 30 seconds. But I have problem of condensate in compresser air. Also this chilly powder seeds itself having some amount of oil this get stuck on filter bag.

These are some photoes I am sending. we have 25 nos. of bag in this chamber and from top of it we have blower to suck air through this filter bag. I dont know material of this filter bag but I will tell you tommorrow.

Very interesting to see the pictures! Please show the grinder too and tell us as much as you can about it.

This is industrial equipment and maybe someone here can help you better if you post a thread showing your photos and call it "filter problem with industrial grinder" or something to get the right person's attention.

The make and model of the system would be helpful too.

If condensate in your compressed air is a large problem, several manufacturers offer what they call a 'comressed air evaporator'. I find this is a very effective way to remove moisture from tool air... things last longer, run better and quieter, there are no more stains in the wood from the occasional 'sneeze' from an air exhaust...

May or may not be of use in your application, but sometimes, several small solutions are the answer.
