Problems solved by technology

The disadvantage of this process route is that the evaporation and drying of the extracted meal further reduces the content and digestibility of protein amino acids, and most small and medium-sized enterprises are not equipped with extraction production lines, but directly sell peanut cakes to peanut oil extraction plants. This link greatly increases the oxidation of cake residue oil and the probability of aflatoxin contamination, and reduces the nutritional level and use value of peanut meal

Abstract

The invention discloses a production method for joint production of a peanut protein concentrate and a byproduct from a peanut meal. The production method comprises the following steps: stirring and extracting a meal powder crushed from the peanut meal under the action of mixed solvents of an aqueous alcohol solution and a vegetable oil extraction solvent or the aqueous alcohol solution and n-hexane; separating the meal powder and the mixed solution to obtain a wet meal after extracting; drying the wet meal at the low temperature; adjusting the content of moisture in the meal, continuing to remove the residual solvent, and forming a peanut protein concentrate product; separating to obtain an alcohol mixed solution and peanut mixed oil containing the vegetable oil extraction solvent; continuing to separate the alcohol mixed solution, recovering the aqueous alcohol solution, wherein the rest substances are a mixture of a raw sugar and a crude fat; then separating the mixture of the raw sugar and the crude fat to obtain a raw sugar substance and a crude fat substance. The dry basis protein content of the obtained peanut protein concentrate is more than or equal to 65%, the content of residual oil in the peanut protein concentrate is less than or equal to 0.5%, the yield of the raw sugar of the peanut (taking a hot rolling cake as a base number) is more than or equal to 7%, and the yield of the crude fat (taking the hot rolling cake as a base number) is more than or equal to 9%.

Description

technical field [0001] The invention relates to the technical field of peanut deep processing, in particular to a production method for extracting and extracting oil from hot-pressed peanut meal or hot-pressed peanut cake to co-produce peanut concentrated protein and by-products. Background technique [0002] Peanut is one of the main oil resources in my country, with an annual output of 14 to 15 million tons, 50% to 60% of peanuts are used for oil processing, and peanut meal, a by-product of peanut oil extraction, has a high nutrient content and is rich in protein , peanut polysaccharides and some insoluble peanut fiber components have high utilization value, especially the crude protein content in peanut meal is 40% to 50%, and the excellent palatability of peanut meal makes it a very important commodity for feed breeding industry Feed protein raw materials. [0003] Existing peanut oil processing technology, mainly divides two kinds of processes of cold pressing and hot pr...
