Problems solved by technology

Disadvantages: large area, incomplete decomposition, serious secondary pollution
Disadvantages: large investment in equipment and large investment
[0005] The key process of producing high-quality organic fertilizer is to fully decompose and ferment the raw materials, but any of the above-mentioned processes has obvious shortcomings, and the fermentation period of the two processes is long, and the phenomenon of incomplete sterilization of raw materials often occurs, and the product quality is not guaranteed

Embodiment 1

[0042] A method for producing tobacco bio-organic fertilizer by steam explosion technology, which is made according to the following steps:

[0043] a. Mechanical crushing of raw materials: crushing tobacco stalks, tobacco tendons, unsuitable tobacco leaves or other crop stalks;

[0044] b. Pressurized blasting: Put the crushed raw material particles in the above step into the steam blasting machine, when the temperature rises to 220°C-250°C, keep the pressure for 2-4 minutes, and start the blasting;

[0045] c. Adding strains: adding strains to the blasted raw material granules obtained in step b, adding cellulose-degrading fermentation bacteria, nicotine-degrading fermentation bacteria and lignin-degrading fermentation bacteria, potassium-degrading bacteria and selenium-degrading bacteria; Mix the raw material granules and strains evenly;

[0046] d. Fermentation: stack and ferment the raw material granules that are evenly mixed with the added strains on the fermentation fi...

Embodiment 2

[0050] A method for producing tobacco bio-organic fertilizer with steam explosion technology, characterized in that it is made according to the following steps:

[0051] a. Mechanical crushing of raw materials: crushing tobacco stalks, tobacco tendons, unsuitable tobacco leaves or other crop stalks to granules of ≤16mm, and keeping the water content of granules ≥10%;

[0052] b. Pressurized blasting: Put the crushed raw material particles in the above step into the pressure holding cylinder of the steam blasting machine, and pass in steam. When the temperature reaches 220°C, hold the pressure for 4 minutes, start the blasting switch, and the materials are ejected from the pressure holding cylinder Go outside the cylinder to complete the blasting process;

[0053] c. Add bacterial classification: add bacterial classification to raw material granule after the completion blasting of gained in step b, add cellulose degrading fermentation bacteria Bacillus licheniformis, Bacillus a...

Embodiment 3

[0057] A method for producing tobacco bio-organic fertilizer with steam explosion technology, characterized in that it is made according to the following steps:

[0058] a. Mechanical crushing of raw materials: crushing tobacco stalks, tobacco tendons, unsuitable tobacco leaves or other crop stalks to granules of ≤16mm, and keeping the water content of granules ≥10%;

Abstract

The invention provides a method for of producing a bioorganic tobacco fertilizer by a steam explosion technology. The bioorganic tobacco fertilizer is characterized by being produced according to the following steps: a, mechanically grinding raw materials; b, pressurizing and exploding; c, adding a bacterial strain; d, fermenting; e, mixing proportionally. The steam explosion technology has the effect of improving the inherent quality of the bioorganic fertilizer: after steam explosion, straws contain a large amount of saccharides and have the humic acid content as high as more than 30%, so that the bioorganic fertilizer is very suitable for growth and breeding of microbes; by adopting a porous structure, the bioorganic fertilizer is beneficial for solid fermentation; the microbes can grow fast on a fermented material treated through the steam explosion because of pressure change; in the steam explosion technology, high temperature and high pressure can effectively kill pathogenic bacteria and eggs in the straws, so that the safety of the bioorganic fertilizer can be ensured; by the steam explosion technology, a link of sterilizing the raw materials is omitted; compared with the conventional process, the steam explosion technology has the advantages as follows: the fermentation time can be shortened by about 10-15 days and the problem of a large floor area of a fermenting workshop is solved.

Description

technical field [0001] The invention relates to a method for producing bio-organic fertilizer for cigarettes by steam explosion technology. Background technique [0002] At present, there are two main production processes used in the production of organic fertilizers, one is the flat strip stack composting process, and the other is the tank type aerobic fermentation process. [0003] The production process of the plane strip stacking composting process: mechanical crushing of raw materials (tobacco stalks, tobacco tendons, unsuitable tobacco leaves and other crop stalks)--raw material sterilization (120°C for 15 minutes)--cloth bacteria feeding (adding bacteria and functional bacteria) --Screening--strip fermentation (mechanical turning)--mixing ratio (inorganic fertilizers, etc.)--testing and packaging (testing N, P, K, organic matter, moisture, etc.)--products. Advantages: small investment, relatively simple process. Disadvantages: large area, incomplete decomposition, s...
