Embodiment 1

[0029] The preparation of embodiment 1 detoxified tung meal

[0030] (1) Preparation of soaking solution: in 3M 3 Add 1 ton of dechlorinated tap water to a reactor with a heating jacket, add 200 grams of 2000 IU / ml liquid acid amylase, food grade CaCl 2. 2H 2 O 20 grams, 10000 IU / ml liquid acid cellulase 1000 grams, adjust the pH value of the solution to 4.5-6.5 with hydrochloric acid;

[0031] (2) tung meal is pulverized and sieved with 80 meshes;

[0032] (3) 1 ton of the above-mentioned tung meal powder is gradually added to the soaking liquid, and constantly stirred when adding, so that the tung meal powder can fully absorb the soaking liquid, and ensure that the liquid level of the soaking liquid is higher than that of the tung meal powder;

[0033] (4) Under continuous stirring, use a heating mantle to increase and maintain the temperature of the reactor at 45-60°C, and then stir once every hour for 48 hours.

Embodiment 2

[0037] The preparation of embodiment 2 detoxified tung meal

[0038] (1) Preparation of soaking solution: Add 1 ton of dechlorinated tap water to a 3M3 reaction kettle with a heating jacket, add 500 grams of 2000IU / ml liquid acid amylase, food grade CaCl 2. 2H 2 O 100 grams, 10000IU / ml liquid acid cellulase 1500 grams, adjust the pH value of the solution to 4.5-6.5 with hydrochloric acid;

[0039] (2) tung meal is pulverized and sieved with 80 meshes;

[0040] (3) 1 ton of the above-mentioned tung meal powder is gradually added to the soaking liquid, and when adding, it is constantly stirred to allow the tung meal powder to fully absorb the soaking liquid, and to ensure that the liquid level of the soaking liquid is higher than that of the tung seed cake powder;

[0041] (4) Under continuous stirring, use a heating mantle to increase and maintain the temperature of the reactor at 45-60°C, and then stir once every hour for 80 hours.

Abstract

The invention relates to soak solution for removing toxin in tung meal and a method for industrialized detoxification. The soak solution is prepared by mixing food-grade CaCl2.2 H2O, 2,000 IU / ml of liquid acid amylase, 10,000 IU / ml of liquid acid cellulose and water. The method for industrialized detoxification comprises the following steps of: adding tung meal powder into the soak solution successively; heating and stirring the mixture; extracting with butarol; separating extract liquor; and separating under reduced pressure at the temperature of between 60 and 80 DEG C to recover the butarol until exhaust liquor becomes paste. By the method for detoxification, over 1 ton of tung meal can be thoroughly detoxified each time, industrialized and large-scale detoxification is realized, and great social and economic benefits are brought.

Description

technical field [0001] The invention relates to a method for recovering useful substances from waste materials, in particular to a soaking solution for removing toxins from tung meal and an industrial detoxification method. Background technique [0002] Aloe tung tree, named vemicia fordii (Hemsl) Airy-shaw in Latin, belongs to Euphorbiaceae (Euphorbiaceae) genus Vernicia Lour. One of the famous economic plants. Its main product is tung oil, one of the best drying oils and widely used in industry. According to statistics, at present, in the field of national economy, there are more than 1,000 products directly or indirectly using tung oil, and with the increasing development of various industries, the use of tung oil will be more extensive. my country is rich in tung meal resources, and it is of practical significance to develop and utilize this resource well. [0003] Tung cake (meal) is mainly the by-product left after tung oil is extracted from tung oil, and its protei...
