We have an issue at our site. we are a producer of seed and kernel product for the bakery industry.
During production we use large steel bins, see the pictures for the bins, we store the seeds in here while they await their next processtep. the product can stay in these bins for several weeks.
The problem with these bins is that they can not be closed, so there is a chance dust and insects can get in the product. Now we are looking for an effective way to close the top but we can not find a good way.
We have thought of several things
- Hard plastic covers: The problem then is that these can break when we stack the bins, plus storage of the huge 2 by 2 meter covers can be a hassle
- Hard metal covers: these wont break but will be heavy and again the storage will be a problem
- Reuseable plastic flexible covers: these can become real dirty and we do not have a facility to wet clean them. (we only have dry cleaning in our facility)
- Sort of large hairnet that covers the whole bin and is only used ones: this will become very costly
Can someone relate to my problem and knows a way to tackle this?
