Embodiment Construction
[0021] Such as figure 2 As shown, the traditional cassava cleaning process is relatively simple. Fresh cassava is firstly dry-cleaned to remove sediment and cassava skin, and then enters the washing process. It is roughly washed by rolling in the washing tank, and then enters the cleaning process. Chips and the like are removed as impurities, there is no recycling process for crushed cassava, and the utilization of reused water is not enough, so the waste of resources is obvious.
[0022] The technological principle of the present invention is: utilizing the difference in specific gravity between cassava and sundries, cleverly combining the effect of recycled water, effectively removing iron blocks and stones in cassava raw materials. The method is: first use centrifugal force to separate the crushed cassava from the sundries, and separate the cassava skin while recycling the crushed cassava, then drop the water and cassava into a washing machine to complete the first reuse w...

The invention provides a water-saving cassava cleaning and processing technology and device. The process comprises the following steps: dry-cleaning and peeling cassava; and discharging precipitation impurities, such as iron and stone, in a screw conveying rinsing bath using the specific gravity difference between the cassava and foreign bodies; wherein through roller cleaning twice, in conjunction with recovery utilization of cleaning water, the cassava is washed clean; cleaning processing devices comprise a dry cleaner, an iron and stone remover, a rinsing bath and cleaning machines; the rinsing bath adopts the screw conveying rinsing bath; the iron and stone remover is mounted below the rinsing bath; the iron and stone remover is communicated with the screw conveying rinsing bath and a back water pump through water conveying pipes; the cleaning machines adopt a structure with two taper roller cleaning machines connected in series; a cleaning water recovery tank, a broken cassava recoverer and an impurity separator are arranged below the cleaning machines; after the cleaning machines clean the cassava, polluted water with broken cassava is separated by the impurity separator, the broken cassava enters the recoverer and is recovered, and part of the polluted water enters a reuse water storage tank, thereby solving the problems that too water is used in the cleaning workshop section of cassava starch production, and too broken cassava is drained.
Description
technical field [0001] The invention relates to a novel water-saving process for the raw material cleaning section in the potato starch processing process and equipment using the process, and is especially suitable for the cassava cleaning section. Background technique [0002] Tapioca starch is dehydrated and dried cassava powder after starch extraction. Tapioca starch has two types: original starch and various modified starches. It is widely used in food industry and non-food industry. The raw materials of cassava starch factory are fresh cassava and cassava dried slices. After fresh cassava is harvested, the soil, roots and woody parts should be removed in time, and iron blocks, iron nails, stones and other sundries should be avoided as much as possible. It is required to harvest on the same day , Enter the factory on the same day, and process on the same day to ensure the freshness of raw materials, thereby improving the extraction rate and product quality. The processi...
