Description

Technical Field

[0001] The invention relates to the technical field of food engineering, in particular to a cassava refiner. Background Art

[0002] Cassava's tubers are rich in starch and can be eaten or used as paste. They are often used to make cassava flour, bread, cassava starch, starch for washing and even alcoholic beverages. However, cassava's roots, stems and leaves contain cyanate toxins and must be bleached and soaked before they can be eaten to remove the toxicity. Therefore, cassava is used in the food industry far more than in daily cooking.

[0003] In the prior art, the large-scale production of cassava flour mainly adopts a wet process, and the steps include washing, peeling, grinding, dehydration, crushing and fine grinding, drying, etc. First, the cassava is washed and treated, and the soil and sand attached to the cassava, as well as the weeds and small stones mixed therein are removed by dry screening, and then the blade cleaning machine is used for countercurrent washing to remove the mud, sand and other impurities in the cassava raw materials. The second step is to grind and crush the cassava, using a segmenter and a rasp mill. The segmenter mainly cuts the cassava into small pieces, and then sends it to the rasp mill for rasp and beating. The third step is to dehydrate the cassava slurry, which is mostly dehydrated by a plate and frame filter press, and the cassava slurry is dehydrated to a water content of about 40%. The fourth step is to crush and finely grind the dehydrated cassava flour cakes, which uses a hammer crusher and a fine powder machine, and the cassava flour blocks are crushed by a hammer crusher, and then the crushed cassava flour blocks are finely ground by a fine powder machine. In the fifth step, the cassava flour is dried to obtain the finished cassava flour, which is then further processed. In the prior art, the coarse grinding and fine grinding of cassava are completed in two steps, which is not only time-consuming but also has high equipment costs and is not conducive to improving the overall process efficiency.
