example 1

[0033] Example 1: The rapeseed cake is removed and pulverized to a fineness within 10 meshes, and quantitatively (2-2.5 tons) is added to the reaction tank, and 0.6% of calcium chloride, 10% of hydrochloric acid, and 4 times of hot water at 65°C are added. Stir fully for 20 minutes, then stand still for 15 minutes, then add 4 times of cold water, stir fully for 30 minutes, stand still for 10 minutes, then filter and drain through the filter tank, and the discharged filtrate is subjected to ion exchange adsorption after simple sedimentation to obtain phytic acid The water sample is then concentrated under reduced pressure to obtain a phytic acid water sample with a concentration of about 20%, then transferred to a crystallization tank for crystallization, the solid-liquid mixture after crystallization is centrifuged, and the separated solid is recrystallized with deionized water. Finally, centrifuge, dry, and crush to obtain a phytic acid product with a fineness of less than 100...

example 2

[0034] Example 2: After the rapeseed cake is removed and crushed, the metal contained in the rapeseed cake and the agglomerated rapeseed cake are crushed, and the fineness is within 10 meshes, and added to the reaction tank. By adding 50-80°C hot water, adding calcium chloride accounting for 0.1-1% of the raw material rapeseed cake, hydrochloric acid accounting for 5-10% of the raw material, and phosphate accounting for 0.2-1% of the raw material, the self-developed vegetable Seed detoxification reaction Stir filter tank for full reaction, discharge liquid, then add 2 to 6 times of water to filter through plate and frame filter press, filter cake is dried by pulse type two-stage airflow dryer, and then graded and screened by high square sieve The rapeseed protein concentrate is obtained, and the extracted water sample is extracted by ion exchange to extract phytic acid, and then purified by crystallization and recrystallization to obtain phytic acid with higher purity.

example 3

[0035]Example 3: The rapeseed cake is removed and crushed to within 10 meshes; quantitatively (2 tons) is added to the reaction tank, 8 tons of hot water at 50-80°C, and 1 kg of calcium chloride are added (the ratio is the raw material rapeseed cake 0.1% to 1% of the meal); fully stir for 15 minutes, and let stand for 10 minutes; add 8 tons of clear water (adding water for the second time), 160 kg of hydrochloric acid (the ratio is 5% to 10% of the raw rapeseed cake), and fully stir for 15 minutes. minute, stand still for 10 minutes; stir for another 15 minutes, stand still for 10 minutes; open the drain port at the bottom of the reaction tank, and the water containing glucosinolate glucoside, polyphenols, phytic acid and other toxic or anti-nutritional substances in the tank passes through the screen Drain after filtering; add 12 tons of clear water again (add water for the third time), stir for 15 minutes, and let stand for 10 minutes; open the drain port at the bottom of the...

Abstract

The invention provides a method for producing the rape seed concentrated protein and phytic acid by deep processing of rapeseed cake dregs: four mixing of the ordinary rapeseed cake dregs, reacting toproduce a filter cake, drying and screening to get the rape seed concentrated protein, which is used for assorted feed of the high sea water fish and eel; furthermore, extracting the discharge waterafter the second, third, fourth mixing reaction by the ion exchange column, which contains poisonous or anti-nutriment such as glucosinolate, polyphenol, and phytic acid, and purifying by a recrystallization means, getting high-purified phytate. The invention has a simple craft, a short line, a few hours and does not introduce harmful and poisonous organic or unorganic complex and benefits to theenvironment protection. The obtained rape seed concentrated protein can partly substitutes high quality import red fishmeal and white fishmeal to be added into the assorted feed, meanwhile, it can recovers the phytate with a high purity so as to get a high additive value of the rape seed process; at the same time, it promotes the technology upgrade of the rape planting, process, feed and aquaculture industry.

Description

technical field [0001] The invention relates to the field of deep processing of rapeseed cake, in particular to a method for preparing concentrated rapeseed protein and phytic acid through deep processing of rapeseed cake. Background technique [0002] Rapeseed is the main oil crop in my country, and its output ranks first in the world. However, the current rapeseed processing industry only produces rapeseed oil and cake, and ordinary rapeseed cake can only be added to compound feed at a ratio of ≤10%, and cannot be used in high-end pomfret, sea bream, eel, etc. In fish farming, the main reason is that rapeseed meal contains toxic or anti-nutrient substances such as glucosinolates, polyphenols and phytic acid. [0003] At present, mainly Wuhan Institute of Technology and Huazhong Agricultural University have published reports and patent applications on the use of rapeseed cakes to produce concentrated rapeseed protein. Wuhan Institute of Technology published "Method for Pr...
