Embodiment

[0015] Example: The slurry is pumped into the primary vertical sieve at the highest point of the process. After screening, the slurry flows into the primary net sieve for screening, and the sieved slurry flows into the raw slurry tank and enters the next process. The primary vertical sieve The slag produced by the centrifugal force falls directly into the primary filter press, and the slag is further pressed dry, so that more starch emulsion is separated from the slag. Flow into the net sieve together, continue to sieve and separate, the slurry screened out by the net sieve flows into the slurry tank, and the whey enters the raw pulp tank and enters a process. The slag pressed out of the primary filter press falls into the mixing tank, and at the same time, it is stirred with clean water, and flows into the secondary vertical sieve through the pipeline through the high-level difference for centrifugation. , used for water distribution of the primary and secondary pulverizers, ...

Abstract

The invention relates to tubers, in particular to a tapioca starch residue separation system, which comprises a raw material cleaning machine, disintegrators, a residue-starch tank, vertical sieves, sieve cleaners, filter presses and the like. Raw materials are cleaned and crushed by a primary disintegrator and a secondary disintegrator to flow into the residue-starch tank, disintegrated residue slurry is sent by a lifting pump from the residue-starch tank to a higher primary vertical sieve, the residue slurry is separated by the primary vertical sieve, dense starch solution passes through a primary sieve cleaner to enter a raw starch tank, the separated tapioca residue is subjected to filter pressing by a primary filter press, dense starch solution and screen washing water after filter pressing pass through the primary sieve cleaner to enter the raw starch tank, fine residue passing through the primary sieve cleaner automatically flows back to the residue-starch tank, the tapioca residue after primary filter pressing enters a stirring tank to be mixed with clear water, and secondary vertical sieving, filter pressing and sieve cleaning are operated as the primary process. Reclaimed water is recyclable, the tapioca residue after secondary filter pressing is dried or directly sold, and the problems that the existing potato starch-residue separation process is complex, large in occupied space and high in operating cost are solved.

Description

technical field [0001] The invention relates to a potato starch slurry and slag separation system, which is especially suitable for cassava starch processing. Background technique [0002] Cassava starch is mainly used as raw material in food, sugar, medicine, feed, textile, paper, chemical and other industrial sectors. The cassava starch production process is a physical separation process, that is, the starch in the cassava raw material is separated from other substances such as cellulose and protein. In the production process, according to the property that starch is insoluble in cold water and its specific gravity is higher than water, starch is separated from the water suspension with water and special mechanical equipment, so as to achieve the purpose of recycling starch. The traditional production process is divided into transportation , cleaning, crushing, screening, sand removal, separation and concentration, dehydration, drying, air cooling, packaging and other pro...
