Embodiment 1

[0032] Weigh 143g of shelled tung kernels and pulverize them, use a Soxhlet extractor to extract 60min at 60°C with 750ml of petroleum ether, take the extract, recover the solvent to obtain 85.9 grams of clear and transparent brown-yellow tung oil, with an oil yield of 60.07%; tung kernel powder 57.1 grams, the cake yield is 39.93%; take 50 grams of Tongren powder, 600 grams of tap water, the solid-to-liquid ratio is 1:12, adjust the pH to 10, the extraction time is 100 minutes, and the extraction temperature is 45°C. Vacuum filtration, the filter residue was washed twice with 50 ml of tap water, and 21 grams of the filter residue was obtained, which was used to extract calcium phytate to prepare organic compound fertilizer; the filtrate was adjusted to PH4.3, and left to stand for 3 hours, and the supernatant was separated, and the lower layer was taken under the condition of 3000r / min Centrifuge for 10 minutes, freeze-dry to obtain 15.8 grams of compound amino acid feed nutri...

Embodiment 2

[0035] Weigh 100g of tung kernels containing husks and pulverize them, use a Soxhlet extractor to extract 650ml of petroleum ether at 60°C for 60min, take the extract, recover the solvent to obtain 9.1g of clear and transparent brown yellow tung oil, obtain 90.9g of tung cake residue, and take 910g of tap water gram, adjust the pH to 10, the extraction time is 100min, and the extraction temperature is 45°C. Vacuum filtration, the filter residue was washed twice with 100 ml of tap water, and 48.7 grams of the filter residue was used to extract calcium phytate to prepare organic compound fertilizer; the filtrate was adjusted to pH 4.3, and left to stand for 3 hours. It was centrifuged for 10 minutes, freeze-dried to obtain 13.1 grams of compound amino acid feed nutritional additives, and the filtrate was sprayed, concentrated and freeze-dried to obtain 27.0 grams of glycosyl amino acid protein feed additives.

Embodiment 3

[0037] Take 50 grams of degreased and deoiled tung cake powder, 600 grams of tap water, solid-to-liquid ratio of 1:12, adjust the pH to 2.-3, heat at 90°C for 6 hours, vacuum filter, wash 2 times with 50 ml of filter residue, and prepare organic matter with 22.5 grams of filter residue Compound fertilizer; add 5 grams of activated carbon to the filtrate, stir and decolorize at 70°C for 30 minutes, vacuum filter, wash twice with a small amount of water, and use the activated carbon filter residue to prepare compound fertilizer; adjust the filtrate to PH4.2-4.3, let it stand for 4 hours, filter, and freeze-dry to obtain 10.7 grams of compound amino acid feed nutritional additives, the filtrate was sprayed and concentrated, and freeze-dried to obtain 13.9 glycosyl amino acid protein feed additives.

Abstract

The invention discloses a processing method comprehensively utilizing a plant oil cake and belongs to the technical field of subsidiary agricultural products processing. Composite amino acid feed nutritional additive, glycosyl amino acid protein feed additive, organic matter fertilizer and calcium phytic acid are prepared by 8 steps of preparing raw materials, preparing cake powder, extraction, hydrolyzation, decoloration, crystallization, digestion and secondary neutralization and sedimentation. The processing method has the following beneficial effects that the obtained products are safe and contain no toxic component or saponin; meanwhile, the products have high nutrition and the protein content is as high as 92.1%; the additives are animal feed nutritional additives with high digestibility and can improve the protein content of feed products and the nutrition utilization rate and lower feeding cost; and in addition, the operation is simple and the method is easy for popularization, thus a great quantity of resources can be saved for society, the environmental pollution can be effectively lessened and the economic benefits can be increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural and sideline product processing, in particular to a comprehensive utilization processing method of vegetable oil cake by further processing plant cake to prepare compound amino acid feed nutritional additive, glycosyl amino acid protein feed additive, organic fertilizer and calcium phytate. Background technique [0002] Vegetable oil cakes are rich in resources in our country, especially tung seed cakes, cottonseed cakes, rapeseed cakes, and tea seed cakes have high economic value, which will be introduced below. [0003] Tung seed cake is the residue after extracting tung oil. Tung tung is a specialty resource in my country, with sustainable development and rich sources. According to statistics, in 1989, the annual output of tung oil in the country was more than 100,000 tons, the rate of machine-extracted oil was 30%, and the rate of cake output was 40%. In the history of our country, the ...
