Description
Technical field
The present invention relates to Protein Extraction technology, be specially a kind of corn starch wastewater and extract phi protein and preparation method thereof.
Background technology
From Semen Maydis, extract corn starch need the technical process through " leaching, two mills, three separation ": " leaching " refers to that Semen Maydis is after cleaning screens out the impurity such as corn cob, stone, use and soak acid reflux type immersion, deliver to broken process after immersion and crush；" two mills " refers to that the plumule in Semen Maydis and fiber, after corase grind and fine grinding, are separated by soaked Semen Maydis；" three separate " i.e. one point plumule, two points of fibers, three points of starch and seitan.
In production process, to add water from soaking the multiple process procedures of beginning, after last one separation circuit " seitan concentrates, is dehydrated, is dried ", be extracted the waste water of seitan concentrated solution just as producing waste water discharge.Wastewater Pollutant COD is at concentrations up to 7000-11000mg/L, and float is up to 700-1500 mg/L.Through assay, the composition of these pollutant is mainly that Semen Maydis is broken, after fine grinding, the material in water is remained in after three separation and Extraction plumules, fiber, starch and protein, its main matter composition is the seitan (protein) of fine particle, account for 50-60%, separately have a small amount of starch, fiber fines.Because waste water generation amount is big, and Pollutants in Wastewater COD, concentration of suspension are high, and big to water environment harm, traditional way is to use physics, biochemical method to process this waste water.
The method is used to carry out sewage treatment technology process longer, and owing to dissolved oxygen during biochemical treatment controls bad grasp, flocculant injected volume and the most bad control of in good time adaptation processed between requirement, so the process control making actual treatment is extremely difficult to perfect condition, discharge beyond standards often occurs, and the power consumption such as water pump, blower fan, compression device is high, accounting for about the 16% of full factory power consumption, and medicament is costly, integrated treatment is costly.
Summary of the invention
The present invention is to solve that existing starch wastewater uses physico-chemical process to process and has that operation is loaded down with trivial details, discharge exceeds standard and problem costly, it is provided that a kind of corn starch wastewater extracts phi protein and preparation method thereof.

When extracting, after corn starch wastewater flow to regulating tank, through high-pressure hydraulic pump by its suction membrane separator, meanwhile, open air pump；In corn starch wastewater enters housing, under the filtration of tubular film fenestra, clear water is discharged and is recycled, dry forms concentrated solution under the barrier effect of fenestra, simultaneously, the compressed air of the airduct blowout near tubular film, to the concentrated solution vortex stirring around tubular film, prevents blocking；Seitan dehydration procedure when the concentration of concentrated solution can reach the concentration that former seitan dehydration procedure sets, in the extraction of direct suction corn starch；When the concentration of concentrated solution does not reaches the concentration that former seitan dehydration procedure sets, and when reaching the concentration of former seitan enrichment process setting, suction corn starch extract in seitan enrichment process, overcome existing starch wastewater and use physico-chemical process to process to have that operation is loaded down with trivial details, discharge exceeds standard and problem costly.
Airduct is arranged on the center of tubular film, housing bottom is provided with outlet pipe, concentrated solution pipe it is provided with out on the housing of tubular film lower end, this structure design corn starch wastewater enters in tubular film, concentrated solution is stayed in tubular film, clear water enters housing and discharges through outlet pipe, and the concentrated solution at tubular film inwall fenestra is stirred by the air discharged in airduct eddy current hole.
The quantity of airduct is some, and it is arranged on outside tubular film around, it is provided with outlet pipe on the housing of tubular film lower end, housing bottom is provided with out concentrated solution pipe, this structure design corn starch wastewater enters in housing, concentrated solution is stayed in housing, and clear water enters tubular film and discharges through outlet pipe, and the concentrated solution at tubular film outer wall fenestra is stirred by the air discharged in airduct eddy current hole.
Corn starch wastewater extracts the preparation method of protein, after using following steps: a, corn starch wastewater to flow to regulating tank, through high-pressure hydraulic pump by its suction membrane separator, meanwhile, opens air pump；B, when corn starch wastewater enters in housing, and under the filtration of tubular film fenestra, clear water is discharged and recycled, dry forms concentrated solution under the barrier effect of fenestra, meanwhile, the compressed air of the airduct blowout near tubular film, to the concentrated solution vortex stirring around tubular film, prevents blocking；C, when the concentration of concentrated solution can reach former seitan dehydration procedure set concentration time, direct suction corn starch extract in seitan dehydration procedure；When the concentration of concentrated solution does not reaches the concentration that former seitan dehydration procedure sets, and seitan enrichment process when reaching the concentration of former seitan enrichment process setting, in the extraction of suction corn starch.
Present configuration and technical flow design are the most reliable, by corn starch wastewater is separated again, stop the phenomenon of contaminated wastewater environment, and obtain protein product, the setting of airduct simultaneously improves separation efficiency and effect, has the advantage that operation is simple, cost is relatively low and easy to operate.
