Paper is the product we use every day. The book we read, the tissue we use, the documents we printed, all these are accomplished with the help of paper.

We have use this product for centuries, our ancient also used paper to paint and record. Have you ever wonder about how paper is made? How can it become so smooth and pliable from the woods?

There are several steps in the production of paper and pulp, from cutting wood to making pulp and from the paper mill to packaging. The starch slurry employed in the process, however, is one of the most crucial procedures that we will cover in this article.

Paper benefits greatly from starch because it gives the paper both size and a coating. Paper has been made with starch for more than 6000 years. From the wet end to the size press, starch is employed. The cost of manufacturing paper is much lower when starch is used.

In order to obtain the molecules required for the application, starch is boiled and hydrated. Water and other chemicals are combined to create starch slurry, which has the qualities needed for spray coating.

Additionally, it functions as one of the binders in the coating formulation for paper, which consists of a blend of pigments, binders, and thickeners. The smoothness, hardness, brightness, and gloss of coated paper have all improved, which has improved its printing properties.

The problems of starch slurry

In the production of paper, the untreated starch slurry can cause various problems. The most direct result is the uneven surface of the paper. Also, due to the bad quality of the starch slurry, the quality of the paper can be affected.

Besides the poor quality of the final products, the production equipment would be also influenced by the unfiltered starch slurry. The equipment is easily clogged by impurities and undissolved starch particles in the starch slurry. More seriously, it can lead to the shutdown of the equipment, which brings huge losses.

The solution for the treatment of starch slurry

The best solution for filtration of starch slurry is automative self-cleaning filter, which can provide continuous filtration and be installed in the production line without affect on the original equipment.

By using a automative self-cleaning filter, manufacturers can easily obtain high-quality starch slurry and eliminate large granular impurities.

Before spraying in the paper mill, fine grits and undissolved starch particles are removed using a Brother Filtration Self Cleaning Filter. It’s crucial to get rid of the large contaminants because they would clog the spraying nozzle and reduce the paper’s quality.


Starch slurry is a crucial process for the pulp & paper industry, appropriate filtration is needed for this step. Brother Filtration has the ability to offer different kinds of automative self-cleaning filters, which can decrease batch time and reduce manual maintenance.
