Filter Press in Starch Production

Starch is a vital carbohydrate derived from plants, such as potatoes, sweet potatoes, and cassava. It is a key ingredient in various industries, including food, textiles, and pharmaceuticals. The starch production involves several steps. Each requires precise filtration to ensure high-quality output. Compared to traditional manual processes, the filter press stands out as an efficient solution.

A filter press is a mechanical device used to separate solids from liquids by applying pressure. It consists of a series of plates and filter fabrics that form chambers, where it traps solids but allows the clarified liquid to pass through. Filter presses are widely used in various industries due to their versatility, efficiency, and ability to handle a wide range of materials.

Starch production involves several stages, including washing, extraction and purification. Filtration plays a pivotal role in these processes to remove impurities, and recycle water. The filter press is particularly well-suited for starch filtration due to its ability to handle high volumes of suspended solids.

Step 1: Washing Wastewater Treatment. During the starch production, large amounts of wastewater are generated, particularly during the washing stage. This wastewater often contains mud and peels. The filter press is used to treat this wastewater by separating the solid particles from the water, allowing the water to be recycled and reused in the production process. This not only reduces water consumption but also minimizes the environmental impact of starch production.

Step 2: Separation of Crushed Pulp. After the starch-containing plants (such as potatoes, sweet potatoes, cassava, etc.) are crushed, the crushed pulp contains a mixture of plant fibers and starch water. The membrane filter press will be used to separate the crushed plant fibers from the starch solutions. This step ensures that the starch water is free from unwanted fibers, making it easier to further process and purify the starch.

Step 3: Starch Filtration. The final step is to remove remaining impurities and achieve a high-quality starch. The filter press is used to filter the starch from water, ensuring that the starch is dryness for the following processes.

The filter press has many benefits in starch production. It cannot only efficiently get the starch, but also greatly recycle water, and lower production costs. With rich experience, Quanhong filter press is a perfect tool in starch production, playing a critical role in wastewater treatment, pulp separation, and starch extraction. With the increasing demand for starch, the filter press will be a reliable and essential technology in modern starch processing.
