The main raw materials for organic fertilizer production include: pig manure, cow manure, chicken manure, etc. from the farm; ingredients include: straw, straw, charcoal, grass charcoal, rice husk, etc. Crop straw is rich in organic matter and is also an important carrier for organic matter elements. Therefore, it is an important auxiliary material for the production of organic fertilizer production process and bio organic fertilizer production. The bio-organic fertilizer produced from straw contains a large number of elements such as nitrogen, phosphorus and potassium required for crop growth, as well as medium and trace elements such as sulfur, calcium, magnesium, zinc, boron, molybdenum, copper and iron. In the organic fertilizer processing of raw materials, auxiliary materials such as straw also indispensable to increase the nutrient elements of organic fertilizer. It can not only meet the needs of crop growth, but also improve the adaptability of crops to adverse environments. The processes required for straw organic fertilizer processing include: crushing, stirring, fermentation and granulator, dryer, packaging machine, etc.
1. Crush:
First, it is necessary to use a straw crusher to crush the straw, and add an appropriate amount of animal manure and other raw materials to a certain fineness to adjust the carbon-nitrogen ratio and water of the compost. The organic fertilizer equipment includes straw crushers, mixers, etc.
2. Fermentation:
The pre-fermentation stage can be carried out in the open air or in a fermentation device. The stacking layer or fermentation device is provided with oxygen through forced ventilation, and livestock and poultry manure is added with straw as the main body. The main fermentation period of aerobic composting is about 3 to 10 days. The required organic fertilizer processing equipment includes fermentation turning machines, organic fertilizer turning machines, etc.
3. Granulation:
It is further dried and pulverized as needed, and then processed into special organic fertilizer. The process required in the deep processing stage is relatively complex, and the required equipment includes: crusher, granulator, dryer, packaging machine, etc.
It is recommended that the indoor trough fermentation of manure is more environmentally friendly for organic fertilizer production.
From manure to organic fertilizer, the price has increased a hundred times, the key is to add fermentation bacteria to do fermentation treatment.
Here is a brief introduction to the method of making organic fertilizer from manure and straw.The organic fertilizer production process includes:Put the fresh manure cleaned from the farm on the same day into the fermentation workshop, add bacteria, synergists and other auxiliary materials, after heating, mixing and stirring, it becomes compost.
In the high temperature, the germs and insects in the feces will be killed, and the macromolecular proteins are decomposed into small molecular proteins that are beneficial to the absorption of crops.
The biological fermentation process can effectively prevent the generation of harmful and odorous gases such as hydrogen sulfide, amine gas and indole in the feces, and completely remove the odor in the feces.The compost is sold in bags after the second aging and decomposing, or directly made into granular fertilizer and stored.
Fermentation cycle of manure organic fertilizer production process is generally 7-10 days, so we recommend customers to use indoor fermentation tank for fermentation.
Rust is a problem often encountered by the organic fertilizer production equipment, especially in rainy days.
Although the machine is not exposed to rain, it will still find rust when it is used later.
Let's explain how to prevent the fertilizer facilities from rusting in rainy days.There is more rain in autumn.
In rainy season, people will store the organic fertilizer equipment in the designated place as usual, but when it is reused after rainy day, it will be found that the organic fertilizer equipment is rusty, some mechanical parts are aging, and some parts are wet.
They are not well preserved, easy to rust and shorten the service life.
The machine should be painted with antirust paint and stored in a ventilated and dry place.2.
There are many sawdust sources in many places, but the pile of sawdust brings great pressure to the environment, especially when the wind blows, the sawdust flying all over the sky has a great impact on the local environment.
The fermented sawdust can be used as nutrient soil ingredients for nursery stock, flower matrix, organic fertilizer, crude protein feed for low animals, etc.It is difficult to ferment in natural accumulation and the fermentation time is very long.
Using Huaqiang organic fertilizer production equipment can realize industrial assembly line processing, and sawdust can be fermented in about 20 days.
Mix and dilute the fermentation agent with rice bran or wheat bran, stir evenly for standby.3.
It is very important to control the moisture content of sawdust by adjusting the moisture content of sawdust to about 65% and adding fresh feces or urea water during the adjustment.4.
Under normal temperature, the temperature of fermentation pile can reach above 50 ℃ on the second day and above 65-70 ℃ on the third day.
