Abstract
The invention discloses a method for preparing sulfur-free konjac fine flour. The method comprises the following steps of: a, selecting a raw material: selecting fresh konjac without rot or foreign matters as the raw material, wherein pesticide residue and heavy metal residue of the fresh konjac are qualified according to the detection; b, peeling and removing apical buds: peeling and removing the apical buds from the selected qualified fresh konjac; c, cleaning: cleaning the fresh konjac; d, quickly squeezing: conveying the cleaned fresh konjac to a squeezer to perform quick squeezing to obtain konjac residue; e, crushing: crushing the konjac residue into granules of 40 to 120 meshes; and f, drying: drying the granules obtained at the step d at the temperature of between 120 and 160 DEG C to obtain the sulfur-free konjac fine flour. The method for preparing the sulfur-free konjac fine flour simplifies the production process and reduces the production cost; the fresh konjac does not produce brown stain during sulfur-free processing; and the obtained sulfur-free konjac fine flour has good luster and high quality.
Description
Technical field
The present invention relates to a kind of method of deep processing of farm products, especially a kind of preparation method who does not have the sulphur konjaku powder with fresh Amorphophallus rivieri as feedstock production.
Background technology
The preparation method of domestic existing no sulphur konjaku powder mainly contains two kinds, a kind of be with fresh konjak through peeling, clean, pulverize making beating, make konjaku powder after diluting deposition, centrifugation, drying with alcohol; Another kind be with fresh konjak pulverize through peeling, cleaning, pulverizing, preliminarily dried, secondary and drying after make konjaku powder; The shortcoming of above-mentioned two kinds of methods is complex manufacturing; Production cost is high; Fresh konjak is prone to take place brown stain, the konjaku powder shade deviation of production in no sulphur process.Konjaku itself is not contain sulphur, but in traditional processing technology in order to prevent that fresh Amorphophallus rivieri from brown stain taking place in process, add sulphur and konjaku carried out color-protecting function, thereby cause the sulfur dioxide in the konjaku flour to exceed standard as color stabilizer.Konjaku reason of brown stain in process has aspect two, and the firstth, cause brown stain thereby the aldehydes matter in the konjaku is oxidized in process, a kind of in addition is microbial metabolism and the brown stain that causes.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method who does not have the sulphur konjaku powder, has simplified production technology, has reduced production cost; Need not add sulphur as color stabilizer; Brown stain can not take place in fresh konjak in no sulphur process, the no sulphur konjaku powder color and luster that obtains is good, and quality is high.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: a kind of preparation method who does not have the sulphur konjaku powder, and this method may further comprise the steps:
A, material choice: selecting not have fresh konjak rotten, no foreign matter is raw material, and it is qualified that the residues of pesticides of fresh konjak and heavy-metal residual detect;
B, remove the peel and go terminal bud: will select qualified fresh konjak peeling and remove terminal bud;
C, cleaning: fresh konjak is cleaned up;
D, squeezing fast: the fresh konjak that cleans up is sent into squeezer squeeze fast, the pan feeding processing speed is 12～25m
3/ h, temperature of charge is controlled at 12 ℃～18 ℃ in the squeezing fast, obtains the konjaku slag, and the moisture Control of konjaku slag is at 30-35%, and the konjaku slag speed of response is 6～12 m
3/ h;
E, pulverizing: the konjaku ground-slag is broken to 40 orders～120 order particles;
F, drying: the particle that step e obtains is dried down at 120 ℃～160 ℃, and promptly getting does not have the sulphur konjaku powder.
Use pneumatic drier to dry among the described step f.
Among the described step f, drying is carried out with the rapid draing mode, and be 0.5～1 minute drying time.
A kind of preparation method who does not have the sulphur konjaku powder provided by the invention, beneficial effect is following:
1, adopt the fresh konjak dry mode after squeezing fast, pulverizing after cleaning to make no sulphur konjaku powder; Lean on physical pressure with the konjaku slag directly from fresh Amorphophallus rivieri separate; Overall process does not have any chemical addition agent; Guarantee product safety, health, pollution-free, molecular structure is not damaged.Do not adding under the prerequisite of sulphur as color stabilizer, utilizing quick Technology in Pressing to make fresh Amorphophallus rivieri dry out fast, preventing oxidizing brown stain, the no sulphur konjaku powder color and luster that obtains is good, and color is the konjaku specific color, and quality is high.
2, with respect to the preparation method of existing no sulphur konjaku powder, the fresh konjak after the cleaning only need squeezing fast,
Pulverizing, dry three steps can obtain not having the sulphur konjaku powder, have simplified production technology, have reduced production cost.
3, do not add sulphur in the whole machining process process and just can make finished product keep good color and luster, thus the content of sulfur dioxide of the no sulphur konjaku powder that has guaranteed to make less than 50ppm, the no sulphur konjaku powder quality that obtains is high.
4, adopt pneumatic drier as drying equipment, dry tenacity is big, the thermal efficiency is high, and treating capacity is big; The dry used time is short; Material contacts with external environment and lacks in the dry run, is not vulnerable to pollute, and has guaranteed end product quality; Simple in structure, volume is little, and is easy to operate.
5, with further processing as semi-finished product, greatly reduce moisture, guaranteed the quality of final products through the konjaku slag after the quick dehydration of squeezing.
