preparation example Construction
[0041] The first aspect of the present invention provides a method for preparing tobacco microporous particles, comprising the following steps:
[0042] Step a. Tobacco waste is removed and dried to obtain material A;
[0043] Step b. Material A is expanded to obtain material B;
[0044] Step c. The material B is obtained by pulverizing and sieving;
[0045] The tobacco waste refers to the solid phase of tobacco leftovers after enzymatic hydrolysis, extraction, and solid-liquid separation;
[0046] Preferably, the tobacco offals include tobacco shreds and / or tobacco shreds.
[0047] Those skilled in the art can use conventional methods to enzymatically hydrolyze tobacco leftovers, extract solid-liquid separation and obtain solid phases, which can be used as raw materials for the preparation of tobacco microporous particles.
[0048] Optionally, the enzymatic hydrolysis refers to the operation of enzymatically hydrolyzing tobacco leftovers with hydrolase and protease, and th...
Embodiment 1
[0079] 1, a kind of tobacco microporous particle, its preparation method is as follows:
[0080] (1) Raw material pretreatment
[0081] The tobacco leftovers used in this example refer to the tobacco powder raw material. The solid phase is removed first, and after confirming that there are no impurities such as sand, metal, and hemp rope, it is dried at 100°C until the moisture content is 20wt%. After drying, the material is sealed and stored in a film bag.
[0082] (2) Microwave heating expansion treatment
[0083] The pretreated material is subjected to microwave heating and expansion treatment, the microwave power is 600W, and the microwave expansion time is 9 minutes.
[0084] (3) crushed and sieved
[0085] The material obtained in step (2) is pulverized with a ball mill, and the pulverized material is sieved with a 20-mesh and a 50-mesh sieve to obtain particles with a particle size of 20-50 mesh.
[0086] (4) Fragrance
[0087] Evenly spray the spices into the gran...
