Embodiment 1

[0018] (1) High-temperature hot pressing: Transfer 1 ton of high-quality peanuts into the stirring steamer, stir and fumigate with high-temperature steam for about 10 minutes, which can effectively kill various molds and harmful microorganisms. Transfer the high-temperature fumigated peanut kernels into a stirring frying pan for constant temperature stirring and frying. The temperature is controlled at 120°C to 125°C. Stir fry for 30 minutes, then send the fried peanut kernels into a screw press, and use traditional physical extrusion The principle is to force the peanut oil to be separated from its original flavor, retaining the original nutritional components of peanuts, various vitamins and minerals to the maximum extent, and refining the peanut oil after high-temperature pressing to obtain 400 kg of fragrant peanut oil. After high-temperature pressing, the residual oil rate in peanut cake is 8%.

[0019] (2) Edible alcohol extraction: Add 2000 kg of edible alcohol with a p...

Embodiment 2

[0027] (1) High-temperature hot pressing: 5 tons of high-quality peanuts are transported into the stirring steamer, stirred and fumigated with high-temperature steam for about 10 minutes, which can effectively kill various molds and harmful microorganisms. Transfer the high-temperature fumigated peanut kernels into a stirring wok for constant temperature stirring and frying. The temperature is controlled at 125 degrees, and stir-fry for 30 minutes. Peanut oil is separated from the original flavor, retaining the original nutrients of peanuts, various vitamins and minerals to the maximum extent, and the peanut oil after high-temperature pressing is refined to obtain 2,000 kg of fragrant peanut oil. After high-temperature pressing, the residual oil rate in peanut cake is 8%.

[0028] (2) Edible alcohol extraction: add 10 tons of edible alcohol with a purity of more than 99% to 3000 kg of peanut cake after high-temperature pressing and extract for 4 hours.

Abstract

The invention relates to a method for synchronously extracting peanut oil and performing high-value utilization to cakes, belonging to the field of deep processing and high-value utilization of peanuts. The processing method comprises the following steps: by taking high-quality peanuts as raw materials, performing high-temperature hot pressing, extracting with edible alcohol, filtering and evaporating, soaking Chinese herbal medicines, performing microbial fermentation, grinding, homogenizing, spray-drying and the like. According to the method, in the step of soaking the Chinese herbal medicines, herba portulacae, herba houttuyniae, fresh rhizoma phragmiti, skullcap, radix astragali seu hedysari, radix glycyrrhizae, acorus calamus and the like are added, and aspergillus parasiticus, aspergillus oryzae, saccharomyces cerevisiae and bacillus are adopted during microbial fermentation. Oil processed by utilizing the method is produced and eaten safely, the price of the peanut cakes is high, the protein solubility is good, the absorption utilization degree is high, the high-nutrition peanut hot-pressed cakes can effectively prevent various bred pest and disease damage as a feed, the cultured animals grow fast, the economic and social benefits are significant, and the high-value utilization of the peanut hot-pressed cakes can be realized.

Description

technical field [0001] The invention relates to a method for synchronously utilizing peanut oil and high-value cake, and belongs to the technical field of peanut deep-processing high-value utilization. Background technique [0002] my country is the world's largest producer and consumer of peanuts, as well as the largest producer and consumer of peanut oil and cake. 50-60% of peanuts in my country are used for oil extraction. Traditional large-scale peanut oil extraction companies mainly use hot pressing to produce peanut oil. After high-temperature pressing, the residual oil rate in peanut meal is between 7% and 9%. Peanut oil pressed at high temperature is sold as Luzhou Pure Peanut Oil. The residual oil in peanut meal is extracted by solvent extraction. After organic solvent extraction, the residual oil rate in peanut meal is less than 0.8%. This part of peanut oil extracted by organic solvent is blended into salad oil and blended oil for sale. Organic solvent extractio...
