Russian Plate and frame filter press application in a starch factory
The starch residue is a good feed material. Still, the starch residue after starch extraction from potatoes is wet, so it must be dehydrated and dried with equipment to become roughage or feed material. Therefore, in the starch production process, the filter press is used to dehydrate starch residue. This article will introduce the plate and frame filter press application in starch production.
Introduction to starch
Starch is a complex carbohydrate consisting of glucose units bonded together. Apart from its use as a food ingredient, starch finds extensive industrial applications in the production of dextrin, maltose, glucose, alcohol, and more. It is employed in various processes like printing paste preparation, textile sizing, paper gluing, and pharmaceutical tablet binding. Starch can be extracted from various starchy sources such as corn, sweet potatoes, wild acorns, and kudzu root.
Working principle of starch solid-liquid separation with plate and frame filter press
The fully automatic plate and frame filter press is primarily utilized to separate cassava flour from water. As the cassava slurry passes through the filter cloth, the solid cassava flour particles adhere to the cloth, gradually accumulating and forming a filter cake that fills the entire filter chamber. Simultaneously, the filtrate permeates through the filter cloth, following the groove of the filter plate toward the channel located at the corner of the plate frame. In this channel, the filtrate is discharged in a concentrated manner. In addition to achieving efficient separation, the automatic plate and frame filter press incorporates a washing process during the separation phase to ensure the production of a filter cake with high purity.
The plate and frame filter press serve a critical role in the cassava flour production line by facilitating the dehydration of cassava flour. This advanced equipment offers automated functionalities, including pressing, filtering, draining, squeezing, loosening, and more. With its highly efficient dehydration capabilities, the plate and frame filter press greatly enhances the cassava flour production process.
Why choose plate and frame filter press for the starch factory?
- Scalability: By adjusting the number of plates and frames, this filter press can accommodate different volumes of slurry, making it versatile across varied operational scales.
- Fine Filtering: The plate and frame design allows for the use of either filter cloth or filter paper, ensuring it can sieve even the finest particles.
- Customizability: Uniwin, as one of the filter press manufacturers, provides a diverse range of designs, sizes, and materials for plates and frames, catering to unique industry requirements.
- Ease of Inspection: The clear delineation between plates and frames simplifies the inspection, cleaning, or replacement of components without the need to dismantle the whole apparatus.
Other applications
Beyond its primary application in starch concentration, the plate and frame filter press in a starch factory can also be used in:
Wastewater treatment: The water extracted during the dewatering process can be purified and recycled back into the production process.
Recovery of by-products: The solid residues captured by the filter press, rich in fibers, proteins, and minerals, can be processed further for various applications, such as animal feed or biofuel production.
