Description
Technical field
The present invention relates to a kind of methods that albumen is recycled from soya whey wastewater, belong to soybean protein recovery technology neck
Domain.
Background technology
Soya whey wastewater is to produce the technique waste water discharged during soybean protein (soy protein concentrate or protein isolate).
Soy protein concentrate and protein isolate production are all using defatted soybean meal as raw material, and the production of soy protein concentrate is generally passed through
The technical process such as acid is heavy, alcohol precipitation, heat treatment realize albumen precipitation separation, and the production for producing soybean protein isolate generally uses alkali soluble
The heavy method of acid.Containing 0.4~0.6% protein in technique waste water, that is, soya whey wastewater caused by alkali extraction-acid precipitation, and lead
If the soybean whey protein of highly-water-soluble and soy-bean whey globulin.
At present, it is direct to carry out anaerobic and aerobic biological treatment to reduce waste water for the processing method of soya whey wastewater
In COD and BOD values, using microorganism come the organic substance in degrading waste water.As CN105439397A discloses a kind of soybean
Albumin milk stripping water treatment technology, which is characterized in that include the following steps：(1) temperature adjustment：Soya whey wastewater adds in steam and carries out
Temperature controls；(2) quenched 1：Whey wastewater after temperature adjustment adds in titanium dioxide acid pickle；(3) quenched 2：Hydrogen-oxygen is added in solution
Change calcium solution；(4) air supporting 1：Anion amide is added in solution, air supporting is carried out by entering air floatation machine 1 after mixer mixing, Gu
Mutually enter scum silica frost pond, liquid phase 1 enters subsequent processing；(5) quenched 3：Calcium hydroxide solution is added in liquid phase 1；(6) air supporting 2：Solution
Middle addition anion amide carries out air supporting by entering air floatation machine 2 after mixer mixing, and solid phase enters scum silica frost pond, and liquid phase 2 enters
Subsequent processing；(7) quenched 4：Titanium dioxide acid pickle is added in liquid phase 2, weakly alkaline solution is adjusted, into anaerobic biochemical treatment system
System.
Although reaching national wastewater discharge standard after above method processing, a large amount of utility in waste water but by
Dispose, in terms of the utilization of resources for, a undoubtedly very big waste.Moreover, waste water disposal facility investment is huge, fortune
Row administration fee is high.Therefore, the method that utility is recycled in developmental research from whey wastewater has important practical significance,
Not only it can guarantee the safety dumping of waste water but also can realize making full use of for resource.
Invention content
For this purpose, the purpose of the present invention is to provide a kind of method that albumen is recycled from soya whey wastewater, this method was both
Can guarantee the safety dumping of waste water can realize making full use of for resource again, have important economic benefits and social benefit.
In order to achieve the above object, the present invention adopts the following technical scheme that：
A kind of method that albumen is recycled from soya whey wastewater, includes the following steps：
(1) it is concentrated after the pH of soya whey wastewater being adjusted to alkalinity；Soya whey wastewater is acid, if directly evaporated
If, chlorion and hydrogen ion can be split into inside water, affect the quality of water in this way, environment is adversely affected, and adjusted
Into alkalinity, then chlorion, sodium ion can be stayed in concentrate, so as to finally also stay in albumen powder, the albumen powder containing sodium chloride
Taste is slightly salty, does not influence other qualities of albumen powder, further increases the flavor of albumen powder；
(2) the clear concentrate regulatory protein a concentration of 12~16% of beans after step (1) is concentrated, for example, 12.5%,
13%th, 14%, 14.5%, 15%, 15.6% etc., it is spray-dried to obtain the soyabean protein powder.
Preferably, in step (1) pH of soya whey wastewater be adjusted to 7.3~9.0, for example, 7.5,7.8,8.1,
8.4th, 8.8 etc., above range is more advantageous to chlorion, sodium ion is stayed in concentrate, and preferably 7.5~8.
Preferably, pH is adjusted is carried out by adding in NaOH solution.
Preferably, a concentration of 3-10% of the NaOH solution, preferably 5%.
Preferably, concentration is carried out using vacuum separation machine.Vacuum separation extracts the moisture of evaporation using negative pressure outward, simultaneously
It can also achieve the purpose that eliminate the unusual smell.The clear water meet the requirement of environmental protection being evaporated.
Preferably, the pressure of vacuum separation machine is-0.5-- 2.0MPa, preferably-1.0MPa during concentration.
Preferably, be concentrated into liquid level be original liquid 0.5-2%, preferably 1%.
In step (2) adjusting of protein concentration be according to the amount of liquid number, measure concentration using centrifuge, so
Dilution water is centrifuged or added afterwards according to ratio.
Then concentrate after regulatory protein concentration utilizes high pressure homogeneous pump, warp through overregulating tank, impeller pump, filter
It crosses high pressure nozzle spray and forms dry powder.
Preferably, the temperature of hot wind is 180-200 DEG C during spraying, preferably 190 DEG C, pressure 30-50MPa, preferably
40MPa.Flow during spraying can be 5-7 cubes m/h, preferably 6 cubes ms/h.
In one embodiment of the invention, described method includes following steps：
(1) it is concentrated after the pH of soya whey wastewater additions NaOH solution being adjusted to 7.3~9.0 using vacuum separation machine；
(2) the clear concentrate regulatory protein a concentration of 12~16% of beans after step (1) is concentrated, it is spray-dried to obtain institute
State soyabean protein powder.
Preferably, the method for the present invention includes following steps：
(1) pH value that soya whey wastewater is adjusted to soya whey wastewater in agitator tank with NaOH solution is 7.3~8,
Into vacuum separation machine, beans are concentrated clearly, moisture forms clear water by evaporation；
(2) it is spray-dried to obtain the soyabean protein powder by the clear concentrate regulatory protein a concentration of 12~16% of beans.
Present invention utilizes vacuum heat pump vapo(u)rization systems, and the protein content of albumen powder obtained is more than 90% after drying.
The present invention is for improving the comprehensive benefit of soybean protein manufacturing enterprise, reducing the environmental pollution journey of soya whey wastewater
Degree has far-reaching significance.The albumen that the present invention recycles is expected to play a significant role in dairy industry and beverage industry.The present invention
It realizes that solids extract is albumen powder in beans stripping water, liquid evaporation is into liquid water, realizes zero-emission, save sewage disposal expense in year
8000000 yuan/line.Have far-reaching significance to mitigating sewage municipal ductwork pressure, improving ambient enviroment, intangible value is big.
