Description

A kind of dry type tapioca(flour) refining technique
Technical field
The present invention relates to starch refining technique technical field, specifically a kind of dry type tapioca(flour) refining technique.
Background technology
Tapioca(flour) is meant after cassava is extracted through starch and dehydrates the powder that forms that it comprises ative starch and modified starch two big classes, is widely used in foodstuffs industry and the non-food product industry diversified utility value being arranged.
Traditional tapioca(flour) process for extracting adopts watermill process usually; Promptly; To buy good cassava earlier and be transported to the pond and clean, adding water with levigator then carries out size degradation, and the tapioca(flour) liquid behind the size degradation produces deposition after leaving standstill for some time; Tapioca(flour) liquid behind the size degradation is carried out the secondary size degradation with levigator; Obtain the tapioca(flour) aqueous solution, with the oscillatory type sieve apparatus with the tapioca(flour) that sifts out with chemical feedstocks bleach, again through desanding, separate, dehydrate, air-cooled, packing is put in storage at last.Adopt watermill process to refine tapioca(flour), have following defective: 1, water loss, current consumption are big, and production cost is high; 2, the wastewater flow rate that produces in the leaching process is big, and cost for wastewater treatment is high, influence ecological environment; 3, plant area is big, equipment cost is high, and the manpower consumption is big, and production process is complicated; 4, long processing time, yield in unit time is few, and production efficiency is low, and output is unstable; 5, in the bleaching process, tapioca(flour) per ton need add 0.1 kilogram/ton in 2 kilograms/ton in sulfuric acid, 0.5 kilogram/ton in chlorinated lime and potassium permanganate, and rotten to prevent that tapioca(flour) from producing, the product that makes has chemical substance residual, and product quality is relatively poor, not environmental protection.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect in the prior art; A kind of dry type tapioca(flour) refining technique is provided; It need not, and consume water consumes coal, current consumption is few, equipment cost is low, human cost is low, working (machining) efficiency is high, production cost is low, and the tapioca(flour) of extraction is the pure natural product, good product quality; And meet modern society's environmental protection requirement, economic benefit and social benefit are high.
For realizing above-mentioned purpose, the present invention adopts following technical scheme.
A kind of dry type tapioca(flour) refining technique, it comprises following procedure of processing:
Steps A, cassava is put into burnishing device carry out polished finish; Remove impurity such as the surperficial mud dirt of cassava, sand
Step B, cassava is put into shredding unit pulverize, wherein, shredding unit can be pulverized the starch more than 95% in the cassava, pulverize the fiber below 10% in the cassava, makes Tapioca Starch;
Step C, Tapioca Starch dropped in the screening plant separate, separate obtaining tapioca(flour) and manioc waste;
Step D, utilize material-gathering device that tapioca(flour) is carried out air-dry, cooling and collect;
Step e, tapioca(flour) is packaged into finished product, warehouse-in.
Wherein, in the said steps A, burnishing device is a polishing machine, and polishing time is 1-2min, and polishing velocity is 12.5-36.5t/h, and the power of polishing machine is 5.5-18.5kw.
Wherein, among the said step B, shredding unit is air-cooled supper micron mill, and wherein, the pulverizing order number of starch is the 80-200 order, and the pulverizing order number of fiber is the 20-200 order.The structure of air-cooled supper micron mill of the present invention and the applicant apply for that on September 10th, 2010 application number is 201010278308.4, and denomination of invention is that a kind of structure of shredding unit is identical.Regulate the wind-force size of kibbler and a small amount of pulverizing that the thickness setter can be realized the fiber below the starch pulverizing and 10% more than 95%, preferably, the pulverizing of fiber is a small amount of pulverizing below 5%.Certainly, shredding unit of the present invention can also be other kibblers, as long as it can realize pulverizing the starch more than 95% in crushing process, and the fiber of pulverizing below 10% gets final product.
Wherein, the pulverizing order number of said starch is 80 orders, and the pulverizing order number of fiber is the 20-80 order.
Wherein, among the said step B, the rotating speed of the crushing knife tool of shredding unit is 1430-4500r/min, is preferably 2900-4500r/min.
Wherein, among the said step C, screening plant is the air-flowing type sieve apparatus, and the order number of the screen cloth of air-flowing type sieve apparatus is the 20-200 order.
Wherein, the screen cloth of said air-flowing type sieve apparatus comprises first screen cloth and second screen cloth, and the order number of first screen cloth is the 80-200 order, and the order number of second screen cloth is the 20-80 order.The structure of air-flowing type sieve apparatus of the present invention and the applicant are on November 16th, 2011 application, and application number is 201110363085.6, and denomination of invention is that the structure of screening plant of micron order powder grain material screening plant and method for sieving is identical.Certainly, screening plant of the present invention can also be other air-flowing type sieve apparatus, as long as it can realize the synchronous screening of starch and fiber in screening process.
Wherein, said step B is 5-10s to the process period of said step D, and pulverising step is short process period with the screening step, helps energy-saving consumption-reducing on the one hand, improves working (machining) efficiency on the other hand greatly, helps reducing production costs.
Wherein, said steps A to the process period of said step D is less than 2.5min.
