A potato acid-thinned starch manual extraction manufacturing plant is a facility dedicated to producing modified starch from potatoes. The process begins with the manual extraction of starch from raw potatoes, typically involving washing, peeling, grating, and then separating the starch slurry from the pulp. This raw starch is then subjected to an acid-thinning process, where a controlled amount of acid is introduced to partially hydrolyze the starch molecules. This modification reduces the viscosity of the starch, making it suitable for various industrial applications such as in paper, textile, and food industries where a lower viscosity starch is desired for better flow and penetration. The manual nature of the extraction implies a more labor-intensive operation, often found in smaller-scale or specialized production units, emphasizing careful handling and traditional methods to achieve the desired starch quality.
