Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food engineering, in particular to a cassava grinding machine. BACKGROUND

[0002] The tuber of cassava is rich in starch, which can be used for food or paste, and is often used to make cassava flour, make bread, provide cassava starch and starch for washing, and even alcoholic beverages. However, the roots, stems and leaves of cassava contain cyanide toxins, which must be treated by soaking to remove toxicity before being edible. Therefore, the application of cassava in the food industry is much more than daily cooking applications.

[0003] In the prior art, the large-scale production of cassava flour mainly adopts a wet process, including the steps of cleaning, peeling, grinding, dewatering, crushing and fine grinding, drying, etc. First, the cassava is cleaned, and the dry screen is used to remove the soil, sand particles and mixed weeds and small stones attached to the cassava, and then the pulp washing machine is used for countercurrent washing to remove the dirt, sand and other impurities in the cassava raw material. The second step is to grind and crush the cassava, using a cutting machine and a grinding machine. The cutting machine mainly cuts the cassava into small pieces, which are then sent to the grinding machine for grinding and pulping. The third step is to dewater the cassava pulp, which is usually dewatered by a plate and frame filter press to a water content of about 40%. The fourth step is to crush and fine grind the dewatered cassava flour cake, which is crushed by a hammer crusher and then fine ground by a fine powder machine. The fifth step is to dry the cassava flour, and finally obtain the cassava flour product for further processing. In the prior art, the coarse grinding and fine grinding of cassava are completed in two steps, which not only takes a long time but also has high equipment cost, and is not conducive to improving the overall process efficiency.
