Milk Filter Bags

Most dairies filter their incoming milk by means of a large tubular filter where bags are supported by perforated stainless steel baskets, (such as the LD filter). The filter bags are designed to filter out grass, grit and other extraneous matter.

The common material has been bleached cotton, which, because of its construction, has more cotton fibre than holes. It is also not very accurate in terms of filtration. The cotton bags, after use, are washed and dried, which is time consuming and not very cost effective.
