Method and special bacteria-adding equipment for adding bacteria after preparing bio-organic fertilizer

Abstract

The invention discloses a method and a special bacteria-adding equipment for adding bacteria after preparing bio-organic fertilizer. When the bio-organic fertilizer is being produced, the water content is 25-30% during the granulation process; after the granulation, the high-temperature quick drying is adopted in a drying cylinder and the water content is not more than 5%; after drying and cooling by a cooling cylinder, a microbial inoculum is added before packaging; furthermore, the special bacteria adding device is adopted to carry out high-pressure haze spraying so as to carry out computation adding; subsequently, the post-procedure of bacteria adding is carried out and the special bacteria adding equipment is selected; the bacterial liquid is added so that the active bacteria number is kept at 2 billion / gram; and before the product is packaged, the humidity needs to be kept at 12% of the water content by mass percentage, thus leading the selected bio-organic fertilizer grains to keep uniform and leading moisture to keep in an environment needed by the added microorganism bacteria. The method effectively avoids the loss of the active bacteria number of the beneficial bacteria in the bio-organic fertilizer, ensures the active bacteria number of the beneficial bacteria during adding the bio-organic fertilizer, and leads the beneficial bacteria to bring beneficial functions tothe bio-organic fertilizers.

Description

field of invention [0001] The invention relates to the technical field of bio-organic fertilizer preparation technology. Specifically, the invention relates to the technical field of a method for post-adding bacteria to bio-organic fertilizers and special bacteria-adding equipment. Background technique [0002] At present, the main raw materials for agricultural production of bio-organic fertilizers are: (1) organic manure raw materials, poultry manure, crop straw, and weathered coal rich in organic matter. (2) Soil beneficial microorganisms that are beneficial to the growth of crops. (3) Appropriate amount of large, medium and trace inorganic nutrients for crops. Adding beneficial microorganisms to organic raw materials, the main difference between the production of bio-organic fertilizers and the production of ordinary organic fertilizers: before granulation production, organic raw materials are added with high-content and high-concentration bacterial agents made of bene...

AI Technical Summary

Problems solved by technology

[0003] However, in the current bio-organic fertilizer preparation process, the beneficial bacteria added in the early stage are often lost during the granulation process, and some organic fertilizer production processes even destroy the beneficial bacteria more thoroughly, causing the beneficial bacteria to be affected. Fatal loss, such as in the production process of disc granulation and drum granulation, often because the product granulation requires high moisture content, it is often dried at high temperature after granulation, the temperature is generally around 200°C, and the duration is generally In more than 15 minutes, traces of beneficial bacteria strains have been found in the dried product granules

In another kind of common extrusion granulation, because at the moment of high-strength mechanical extrusion, the temperature is often as high as above 60°C, even if the low-temperature drying method is used later, the beneficial activity is still lost. It is also the main reason why the content of beneficial microorganisms in bio-organic fertilizers on the market is somewhat low
