Description

Fertilizer-based Fertilizer Manufacturing Method

The present invention makes it possible to produce excellent organic fertilizers in the production of fertilizers based on phosphorus.

Phosphorus-based fertilizer is an excellent organic fertilizer produced by the complex fermentation of microorganisms and is fertilized in the soil to supply nutrients to the soil to improve plant productivity.

The present invention is a mixture of the main raw materials and by-products such as briquettes, shell husk chaff powder, etc. in a specially prepared fermentation tank while injecting air at a suitable temperature, pH, water content state to fermentation and fermentation ingredients such as manure and briquettes, shell meal Since the materials are to produce excellent organic fertilizers complementary to each other, the entire process of the embodiment can be divided into three steps in the process, and each of these steps is continuously performed.

[Step 1]

The pretreatment process removes rubber, plastic, glass, ceramics, and other foreign substances contained in the serving to facilitate the treatment of fertilizers in a 400 tons of manure storage tank.

Filter foreign substances are installed at the inlet of the manure storage tank to filter and remove the first foreign substances, and a basket is also installed at the bottom of the tank to remove the second foreign substances with a steam hoist.

Odor occurs in the manure tank, but the odor spill does not appear because the manure transfer process is transported in a closed tube.

When transferring manure to fermenter, add additives such as briquettes and waste shell meal.

Their input rate is 200 tons (58.8%) of manure, 110 tons (32.4%) of briquettes, 9 tons (2.6%) of waste shell meal, 9 tons (2.6) of rice husk powder, 9 tons (2.6) of sawdust powder, 3 tons of agricultural and fishery waste. (0.9%) Traces of known fermentation accelerators.

[Step 2]

In order for each raw material input into the fermenter to be well fermented and composted, a mixer equipped with three stages of lungs is used for complete mixing of raw materials and oxygen supply, and heating wire and insulation are maintained to maintain proper temperature of enzyme activity. A temperature control device was installed to maintain 38 ° C outside, and an air pump was installed to inject 200 liters of air per minute to provide oxygen for fermentation.

The synergistic effect of the serving stock of the present invention and the rich mother material is as follows.

The briquette material is similar to soil, so its absorption rate is high, so it can act as a beneficial factor for solid toby. In particular, its high gas adsorption power makes it strong in deodorizing action and prevents acidification of soil with weak alkaline components.

Shell lime (CaO) 39% and organic matter 41% quicklime (CaO) neutralizes the acid produced during the metabolism of microorganisms and regulates the physiological equilibrium between various inorganic salts in the cell to activate microorganism activity. Shellfish prevents the degradation of microorganisms due to the acidic neutralization, especially the production of organic acids at the beginning of the composting process, thereby promoting an increase in maturity and the complete decomposition of harmful intermediate products.

In addition, the crushed shell meal also serves to promote the coagulation of the colloidal material and intermediate product in combination with the water in the fermentation tank.

Other additives such as chaff powder and sawdust also help to increase odor adsorption, water absorption and fermentation.

Odor occurs immediately after mixing raw materials in the fermentation tank, but as the fermentation proceeds, it shows a decreasing trend as described in the table below.

TABLE 1

This is due to the interaction of briquettes, shell meal, chaff powder, sawdust, etc. added during the composting process by fermentation.

The fermentation tank is fermented for about 7 days, and the temperature and pH change ranges are measured as shown in the second chart below.

TABLE 2

The water content of the mixture in the fermentation tank is about 50-60%, and it can be seen that the conditions in the fermenter are the most suitable conditions for the fermentation microorganisms to be seen from the temperature and pH change shown in the first diagram.

[Step 3]

Fermented fermented product transferred from fermenter to stable tank contains 50 ~ 60% of water, and sodium hypochlorite (NaOCI) is added to remove odors and germs that may remain.

Subsequently, it is granulated with a ventilator, and the final moisture content is processed to 20% or less with a forced draft drying device, and then packaged into a product. The finished product of the present invention is a fully deodorized sterilized organic alkaline fertilizer which can prevent acidification of the soil and is a high quality phosphate-based organic fertilizer containing nitrogen, phosphoric acid and bran.
