Embodiment 1

[0065] (1) Collection and crushing: Most of the unsuitable tobacco leaves contain pathogenic bacteria and insect eggs. Firstly, the unsuitable tobacco leaves are collected in a closed way to reduce the pollution of diseases and insect pests to the tobacco field, and are pulverized by a shredder.

[0066] (2) High-temperature and high-pressure separation and sterilization treatment: After collecting and crushing unsuitable tobacco leaves, transport them to the filling port of the separation tank with a lifter, reach the inside of the separation tank, and raise the temperature of the raw materials in the container to 158-164°C. The steam pressure reaches 0.5-0.6Mpa, and the duration is within 1 minute, and then the outlet is quickly opened to complete the sterilization and meet the harmless treatment standard.

[0067] (3) Fermentation step: Mix unsuitable tobacco leaves, nutrient sources and auxiliary materials that have been sterilized and harmless in a mass ratio of 70:10:20, ...

Embodiment 2

[0083] (1) Collection and crushing: Most of the unsuitable tobacco leaves contain pathogenic bacteria and insect eggs. Firstly, the unsuitable tobacco leaves are collected in a closed way to reduce the pollution of diseases and insect pests to the tobacco field, and are pulverized by a shredder.

[0084] (2) High temperature and high pressure separation and sterilization treatment: After collecting and crushing unsuitable tobacco leaves, transport them to the filling port of the separation tank with an elevator, and reach the inside of the separation tank, raise the temperature of the raw materials in the container to 158°C, and the steam pressure It reaches 0.6 Mpa, lasts for 50 seconds, and then quickly opens the outlet to complete the sterilization and meet the harmless treatment standard.

Abstract

The invention discloses a process technology for producing a functional fertilizer by utilizing tobacco waste. The process technology for producing the functional fertilizer by utilizing the tobacco waste comprises the following steps: collecting tobacco waste, smashing, carrying out high temperature and high pressure separation and sterilization treatment, and fermenting, wherein the fermenting step concretely comprises the steps of mixing the tobacco waste, nutritional substances and auxiliary materials in mass ratio of (70-75):(10-20):(10-20), regulating moisture content to be 50-60% and adding AT fermentation substance accounting for 0.05-0.1% of the total weight of fermentation materials. According to the process technology for producing the functional fertilizer by utilizing the tobacco waste, the AT fermentation substance can overcome influence of nicotine in the tobacco waste, quick warming and decomposition can be realized, high temperature higher than 60 DEG C is formed in a decomposition process and can be maintained for more than one week, pathogenic bacteria, eggs, weed seeds and the like can be effectively killed, and macromolecule substances not applicable in tobacco leaves can be quickly converted into micromolecule substances which can be absorbed and utilized, such as micromolecule sugar and micromolecule amino acid, through treatment by virtue of a high temperature and high pressure separator and high temperature decomposition; volume weight of soil can be reduced, formation of a soil granular structure can be promoted, and soil fertility and soil microbial activity are improved; the nicotine has a strong killing effect on plant diseases and insect pests in soil, so that soil-borne diseases can be prevented and qualities of tobacco, vegetables and fruits can be improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco waste treatment, and in particular relates to a technology for producing functional fertilizer by using tobacco waste. Background technique [0002] Traditional agriculture is facing problems such as environmental pollution, ecological destruction, and resource depletion. Therefore, it is an important task for the development of modern agriculture to explore a high-quality, efficient and recyclable new agricultural production mode through the development of circular economy, and to form a production mode of "resources→agricultural products→renewable resources→agricultural products". [0003] Tobacco is one of the leading industries in my country's rural economy, and the country's tobacco planting area has reached more than 15 million mu. Tobacco growth requires a large amount of potassium and phosphorus elements, and potassium and phosphorus resources need to be added to the soil every year. Tob...
