Abstract
The characteristic lies in that the parchloric acid or tartaric acid is added in the alcohol waste liquid to form potassium perchlorate or potassium tartrate and isolate the precipitaion. The filtration residue is used to make composite fertilizer, the supernatant liquid is condensed or powdered and can be used as a portion of fowl and animal fodder. the deprivation rate of potassium in the waste liquid of alcohol is over 90%. It provides a new method for comprehensive utilization of wastes.
Description
The invention relates to a method for producing livestock and poultry feed by using alcohol waste liquid, belonging to the comprehensive utilization technology of molasses alcohol waste liquid in a sugar refinery.
The molasses alcohol waste liquor is waste liquor discharged after the sugar-making by-product molasses of sugar refinery is fermented and the liquor is distilled out alcohol in a distillation tower, the waste liquor contains a plurality of mycoprotein, aminoacid and trace elements, and according to the determination data of the dry components of the alcohol waste liquor provided by a certain factory, the molasses alcohol waste liquor comprises the following components in percentage by weight: aspartic acid 2.75, threonine 0.16, serine 0.21, glutamic acid 1.55, glycine 0.24, alanine 0.46, cystine 0.12, valine 0.32, methionine 0.13, isoleucine 0.18, lysine 0.09, crude protein 18-21, calcium 7.54, nitrogen 3.37, P2O50.50，K2And (4.8). So richProtein and amino acid are good raw materials of animal feed, but the potassium content is too high, so that the protein and amino acid cannot be directly used as feed for feeding livestock, or the digestive system of the animal is damaged, and diarrhea and dehydration are finally caused to die. Although the Chinese patent 95103709.9 describes that the dry powder of alcohol waste liquid is added according to 3-10% of the total weight of the complete feed, the dry powder of alcohol waste liquid cannot be blended for a long time.
According to the reports of the literature, the potassium removal of the alcohol waste liquid by zeolite is adopted in the sugar refinery, which is widely known in Yunnan province, and the mechanism is that the potassium ions in the alcohol waste liquid are adsorbed by utilizing the microporous adsorption effect on the surface of the zeolite, but the zeolite also adsorbs other useful cations such as sodium, calcium, magnesium and the like while adsorbing the potassium, and the elements are beneficial to the growth of animals. In addition, the zeolite is quickly saturated after being adsorbed for a period of time, the surface needs to be eluted by acid or carbonate, new pollution is caused by the emission of the acid, and the zeolite needs to be eluted frequently due to the overlarge viscosity of the alcohol waste liquid, so that the continuity of production is damaged, and the production cost is increased.
The invention aims to provide a method for removing potassium from molasses alcohol waste liquid in a sugar refinery and producing livestock and poultry feed, which has the advantages of simple process, good potassium removal effect and lower cost and can be continuously produced.
The method comprises the processes of concentration and potassium removal of the alcohol waste liquid, separation of concentrated solution, re-concentration or drying, feed preparation and the like, and the specific technological process comprises the following steps:
1. the alcohol waste liquid is concentrated until the brix is between 10 and 70BX, preferably 40 to 60 BX. The solution is too dilute and too concentrated, which is not favorable for the potassium removal reaction, and the concentration method can adopt a steam heat-insulation evaporating pot or a spray hot air contact method.
2. Reaction for removing potassium, putting the concentrated waste liquid into a reaction tank, adding potassium removing agent while stirring, screening the potassium removing agent by the inventor, and selecting perchloric acid (HClO)4) Or tartaric acid (H)2C4H4O6) The chemical reaction is as follows:
reaction of KClO4Or KHC4H4O6Quickly depositing at the bottom of the solution, the potassium removing efficiency can generally reach about 90%, and the adding amount of perchloric acid or tartaric acid is added according to the potassium content in the alcohol waste liquid.
3. Centrifuging, discharging the obtained precipitate from thebottom of the reactor, slightly clarifying, and separating the precipitate with centrifuge or filtering out the residue with plate-and-frame filter.
4. Concentrating again, concentrating the potassium-removed solution with evaporating pot or thermal spray concentration method to obtain concentrated slurry with solid content of above 70% or directly drying into powder, and spray drying with hot-blast stove.
5. The thick slurry or the dry powder is directly added into feed raw materials to be mixed, the contents of starch, protein and various trace elements of the raw materials are analyzed before mixing, and then the adding amount of the raw materials is adjusted according to the requirement, so that the mixed feed is suitable for the requirements of various livestock and poultry animals.
The invention has the advantages that:
1. can remove over 90 percent of potassium in the alcohol waste liquid, is simpler than a zeolite adsorption method, is easy to operate, saves equipment investment and has no secondary pollution.
2. The waste alcohol liquid can be mixed into the feed in a large amount, the waste is utilized, and the waste is changed into valuable.
3. The prepared feed has good palatability for animals, high amino acid and protein content, saves a large amount of grain feed, and enables the animals to grow rapidly.
4. The filtered or centrifuged slag contains a large amount of potassium salt and organic matter, and thus can be used as a high-quality potassium-containing fertilizer to be applied to farmlands.
The following are examples of the present invention:
in the first embodiment, the first step is,
evaporating and concentrating the alcohol waste liquid output from the alcohol distillation tower to 40-60BX by a triple-effect evaporation tank, introducing into a reaction tank, and adding 30-50 kg of HClO per ton of concentrated liquid4Stirring the reaction mixtureNaturally precipitating, taking out the precipitate from the bottom, filtering with a plate-and-frame filter, mixing the residue with compound fertilizer or directly applying to farmland, concentrating the filtrate, mixing with feed materials such as soybean meal, corn flour, fish meal, etc., granulating, and oven drying to obtain high-quality feed for feeding livestock and fowl.
Example two, the alcohol waste liquid from the distillation tower is concentrated to 50-70BX by an evaporator, put into a reaction tank, added with 40-60 kg of tartaric acid under stirring per ton of alcohol waste liquid, naturally precipitated after reacting for 1 hour, separated by a centrifuge to obtain precipitate as high quality fertilizer for crops, and the concentrated waste liquid after reaction is dried again to powder by a spray dryer, mixed with feed in a weight ratio of 50% and directly fed to poultry.
Example III direct preparation of HClO without concentration of the waste alcohol from the distillation column, BX 10-204Adding 15-20 kg of waste liquid per ton, absorbing supernatant after reaction and precipitation to prepare liquid feed, directly conveying the liquid feed to a pig farm for feeding pigs, and adding rice bran, corn flour or bean flour during feeding, wherein the liquid fertilizer is popular with farmers, and the precipitate is directly pulled to a rice field for topdressing, and the yield of rice is increased by 10-15% compared with that of the rice field without waste liquid precipitate after trial in the early rice field in 97 years.
The application example is as follows:
a certain chicken farm uses the potassium-removed alcohol waste liquid concentrated solution in the embodiment I, the concentrated solution is mixed into broiler feed according to the weight ratio of 40 percent, compared with common feed as reference, 100 chickens are divided into two groups, and as a result, 50 chickens fed with the feed mixed with the alcohol waste liquid averagely gain 0.16 kg of weight per chicken after being fed with the feed mixed with the alcohol waste liquid for 50 days than the other 50 chickens fed with the common feed, the chickens eat actively in the feeding process, the diarrhea phenomenon does not occur, the growth is good, and the effect of the feed produced by the method is good.
