Abstract
A process for reclaiming the organic substance in the sewage of food processing factory includes such steps as mixing the oily mud coming from air dissolving apparatus with the liquid blood of animal, regulating pH=4-11, and heating to more than 60 deg.C to obtain a solid product containing blood protein.
Description
[technical field]
The present invention relates to the waste water processing of food processing plant, particularly a kind of processing and treating method that contains the trade effluent of fat, protein and other organic substance.
[background technology]
Almost each food-processing producer all uses a large amount of water to come cleaning food raw material, particularly animal to resemble pig, ox and poultry and slaughters processing producer.In the waste water of washing very high fat, protein and other organic substance are arranged.If these organism (resemble fat, protein or carbohydrate) flow into water drain or the river can cause high-load biological organism, bring difficulty for the water conditioning of water drain, and cause water pollution.In order to reduce the pollution of water quality, dissolved air floatation device (DAF-dissolved air flotation) can be used to make organism such as fat, protein and carbohydrate to combine a kind of greasy filth shape material of formation with nontoxicity chemical and dissolved air, and on climbing up on top of the water.Utilize mechanical means to separate this greasy filth and water then.But the general very oiliness of this greasy filth is particularly slaughtered processing producer to animal.Greasy filth generally contains about 80% moisture content.This greasy filth is difficult to processed processing, resembles to remove moisture content and be dried into solid product.A lot of animals are slaughtered processing producer greasy filth are thrown away place away from the city, have not only wasted these and have contained fat and proteinic material, and can cause environmental pollution.Also can cause transmission of disease if wherein have the animal germ.Slaughter the greasy filth of processing producer for animal, solids accounts for 20%.In this solids of 20% fat account for 11% and protein account for 7.5%.These organism can be used as the feedstuff raw material of animal, have valuable nutrition.For cereal processing factory, contain more carbohydrate in the greasy filth.After the processing of dissolved air floatation device, the organic content in the waste water is greatly reduced.
If the greasy filth that the application of heat method is slaughtered processing producer to animal is heated to about 100 ℃, fat becomes oil can be separated through whizzer, and solids also can be separated through whizzer.Three-phase centrifuge separates fuel-displaced, the aqueous solution and solids, but inferior separating effect, and the aqueous solution is very muddy.The fat mass of separating is relatively poor.Generally be semi-solid state at normal temperatures, before using, need heat treated to make it become liquid state, could mix with other feedstuff raw material then as feed fat raw material, very inconvenient.The selling price of this fatty raw material is below other half.
Slaughter in the course of processing animal, animal blood accounts for the 3-3.5% of living animal.Every pork pig of China 3 kilograms of pig blood are arranged approximately.Can get pig blood and estimate about 1.5 hundred million kilograms national every year, and as seen its annual production is considerable.The total amount of poultry blood is also considerable.Every beef cattle has more ox blood, but is less than pig and poultry in the amount of slaughtering of Chinese ox.How animal blood being utilized well in addition is a thing that needs to be resolved hurrily.Animal blood has very high protein content, and whole blood has protein 85% (in solid-state) approximately.Blood plasma is separated with erythrocyte albumen after centrifugation.Blood plasma has about 77% protein (in solid-state), its by spraying drying after product colour more shallow.Erythrocyte albumen accounts for the overwhelming majority in whole blood, about 80% (in solid-state).Red corpuscle albumen has 91% protein (in solid-state) approximately.Red corpuscle albumen has 91% protein (in solid-state) approximately.Whole blood and erythrocytic animal blood products have special blood garnet, have the blood smell to contain a large amount of protohemes, and agreeable to the taste sense is poor, is not generally liked by animal.
At the processing technology of above-mentioned greasy filth and goods such as animal's whole blood or red corpuscle albumen from the dissolved air floatation device, carried out a large amount of scientific researches both at home and abroad and produced some patented technologies.United States Patent (USP) 4138505 (1979) has been invented a processing technology, and animal blood mixes mutually with fat after heating, and increases alkalescence to pH value 11 to 13 again and forms the gel-like prod that a kind of fat and protein connect together.This processing technology is in strong basicity, and the blood smell and garnet still exist.Wang Chuanhuai etc. (1992) use hydrochloric acid hydrolysis, decolouring, depickling and drying and other steps to prepare pig blood becomes amino acid.Yan Benju etc. (1994) the with an organic solvent precipitator method come to produce superoxide-dismutase from pig blood and meet amino acid.With the hydrolysis of 6N hydrochloric acid reflux, hydrolyzed solution catches up with acid to thick with thickener.After the dilution, hydrolyzed solution filters with decolorizing with activated carbon, passes through the anion-exchange column depickling again, has been concentrated into amino acid and has separated out cooling drying again.United States Patent (USP) 5514388 (1996) has been invented a processing technology, increases the paramount strong basicity of haemproteins, adds fatty the mixing, and then reduces the pH value to acid 3 to 5 formation container.Increasing considerably or reducing of acid-basicity makes mixture toughness change greatly, and makes product have very high ash.United States Patent (USP) 5880266 (1999) has been invented a patented technology, washes with water, potential of hydrogen variation, membrane sepn and acid-basicity return haematochrome is removed from animal blood haemoglobin.The course of processing relates to a plurality of procedure of processings.United States Patent (USP) 6229031 (calendar year 2001) has been invented a patented technology, and lipid acid and calcium oxide are prepared into calcification soap form in strong basicity.This calcification soap products can be used for increasing milk yield by milk cow.But animal dislikes the taste of calcification soap, and tooling cost also is a factor.United States Patent (USP) 6368657 (2002) is that the author has invented the greasy filth that a patented technology changes the dissolved air floatation device and becomes solid product, and product even not have physics oiliness fat content in product be 40%, moist product can be become drying products by general drying plant drying.But product colour is still very dark, but also scent of.
[summary of the invention]
The present invention will solve in order to solve existing food processing plant wastewater through organic matter treatment process, can not effectively remove the technical problem of this greasy filth oiliness and environmental pollution, and organic working method in a kind of food processing plant waste water is provided.
We find can be mixed by liquid animal blood (whole blood or erythrocyte) from the greasy filth of dissolved air device, and acid-basicity pH value can be adjusted to 4 to 11, is heated to the solid product that forms a kind of greasy filth and haemproteins more than 60 ℃.This solid product does not have oiliness.Some feed grade chemical resembles calcium or magnesium compound also can help to form this solid product.If hydrogen peroxide or peroxide salt (for example calcium peroxide or peroxidation are received) are added into, concentration can be (part by weight) below 3%, general about 0.3% can since change product color from dark red color to brown or yellow.For example the hydrogen peroxide of 10 grams 33% joins in the greasy filth and haemproteins mixture of 1000 grams (0.3%) after heating.Except that color, local flavor (particularly smell) and microbe quantity are clearly improved.Free moisture content can be removed with whizzer, filtering net or squeezer.Solid product can also can be processed with other products and be used by convection drying and use.Superoxide can also help to form this solid product, make its particle bigger, be convenient to the separation of free moisture content more.Superoxide can be used, and also can not be used, and the use of superoxide can prepare more valuable solid product.Superoxide uses before can being removed at free moisture content, also can be used after free moisture content is removed, and this depends on uses the particular case that technology and equipment are arranged in this technical process.Greasy filth also can be heated earlier and be processed into greasy filth oil (particularly animal being slaughtered producer) in addition, and greasy filth oil has more stable fatty amount, so prepared solid product has stable fat and protein content.
This prepared solid product can be applied the general feed or the raw material of organic fertilizer, also can be applied to helping in the milk cow feed to produce more milk.Protein and the fat of finding this organic solid-state product in the test of giving an example can be used for producing milk by milk cow.
This new processing technology adapts to the greasy filth or the processing of greasy filth oil of any food producer, and animal blood derives from any animal's whole blood or erythrocyte resembles pig, ox, chicken, duck or sheep blood.
Working method of the present invention has following advantage:
1. product does not have oiliness.
2. improve the smell of product.
3. improve the color of product.
