Embodiment 1
[0025] The present embodiment provides a kind of preparation method of natural Sapindus chinensis air purification medium, the preparation method of described air purification medium is as follows:
[0026] (1) hot air drying: take the clean Sapindus fruit, put it into a dryer and dry it with hot air for 2 hours at 80°C, so that the water content of the fruit does not exceed 4%;
[0027] (2) Separation of the seed coat: cutting and separating the Sapindus fruit with a water content no more than 4%, to obtain the Sapindrome seed and the Sapindrome pericarp;
[0028] (3) Seed pulverization: the obtained Sapindus seeds are mechanically pulverized twice, and passed through a 10-20 mesh sieve to obtain Sapindus seeds pulverization;
[0029] (4) oil extraction: extracting oil by pressing the crushed material of Sapindella seed, to obtain Sapindant seed oil and Sapindant seed oil residue;
[0030] (5) Drying of the oil residue: place the oil residue of Sapindus seeds in an oven at 8...
Embodiment 2
[0041] The present embodiment provides a kind of preparation method of natural Sapindus chinensis air purification medium, the preparation method of described air purification medium is as follows:
[0042] (1) hot air drying: take the clean Sapindus sapindus fruit, put it into a dryer and dry it with hot air for 1.5 hours at 85°C, so that the water content of the fruit does not exceed 4%;
[0043] (2) Separation of the seed coat: cutting and separating the Sapindus fruit with a water content no more than 4%, to obtain the Sapindrome seed and the Sapindrome pericarp;
[0044] (3) Seed pulverization: the obtained Sapindus seeds are mechanically pulverized twice, and passed through a 10-20 mesh sieve to obtain Sapindus seeds pulverization;
[0045] (4) Oil extraction: extract the oil from the crushed seeds by ethanol extraction, and extract the crushed seeds and 95% ethanol solution at 55° C. for 4 hours according to the ratio of solid to liquid of 1:5. Sapinberry oil and Sapin...
Embodiment 3
[0052] The present embodiment provides a kind of preparation method of natural Sapindus chinensis air purification medium, the preparation method of described air purification medium is as follows:
[0053] (1) hot air drying: take the clean Sapindus fruit, put it into a dryer and dry it with hot air for 1 hour at 90°C, so that the water content of the fruit does not exceed 4%;
[0054] (2) Separation of the seed coat: cutting and separating the Sapindus fruit with a water content no more than 4%, to obtain the Sapindrome seed and the Sapindrome pericarp;
[0055] (3) Seed pulverization: the obtained seeds are mechanically pulverized twice, passed through a 10-20 mesh sieve, and sieved to obtain the pulverized seeds;
[0056] (4) Oil extraction: extract the oil from the crushed seeds by ethanol extraction, and extract the crushed seeds and 95% ethanol solution at 60°C for 3 hours according to the solid-liquid ratio of 1:5. Sapinberry oil and Sapinberry seed oil residue are ob...
