In order to supply nutrients to the growth of crops and plants more efficiently, it is necessary to start bio fertilizer production. Because it can improve the efficiency of plants to absorb nutrients through the life activities of microorganisms contained in it. But compared with organic fertilizer manufacturing, it has a more complicated process. Besides fertilizer making, it is also essential to focus on microorganism adding. Then how to make biofertilizer smoothly? For this, there are various fertilizer machines for your choice, which can help you finish biofertilizer production easily and quickly.

Bio organic fertilizer making
  • Cpacity: 1-20 t/h
  • Area: 800-10,000 ㎡
  • Material: Carbon steel Q235/Alloy

  • Voltage: 220v/380v/415v/440v/480v(50Hz/60Hz)

  • Application: Disposal of aniamal manure, straw, sawdust, branches, biogas residues, etc.

What are the commonly used microorganisms in bio fertilizer making project?

The use of microbial strains is the core of bio organic fertilizer preparation. In general, microorganisms are divided into two types: composting microbial inoculant and functional bacteria. And you need to add them in different stages:

Composting microbial inoculant

As the name suggests, composting microbial inoculant is widely used in biofertilizer composting process. It is beneficial for facilitating manure composting and eliminating the odor of animal manure. And commonly, this microbial agent is a kind of complex bacteria. Including photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, penicillium, trichoderma, etc.

Functional bacteria

But the functional bacteria is suitable to use after composting, because high temperature will kill it. It contains azotobacter, phosphobacteria, silicate bacteria, lactic acid bacteria, pseudomonas, actinomycetes, etc. They play different roles in bio fertilizer production. You can choose according to your needs.

When is it suitable to add functional bacteria in bio fertilizer making?

Which step is the best choice to add functional bacteria

When you produce powder biofertilizer, it is an ideal choice to add functional strains after composting. But if you plan to make granular biofertilizer, it is advisable to spray microbial agent after granulation. In this way, the survival rate of functional bacteria can reach more than 95%.

How to provide a suitable environment for functional bacteria living

If you want to produce high quality bio fertilizer, you also need to focus on the adjustment of temperature, moisture content, organic matter content and C/N ratio.

What you need to do for better bio fertilizer composting?

In general, composting plays an important role in biofertilizer production. Because it can eliminate harmful substances and unpleasant odors of manure. Then how to start bio fertilizer fermentation better? Besides adding composting microbial inoculant, using a professional compost machine is your optimal option. It can turn materials regularly to supply oxygen and dissipate excessive heat. They are beneficial for better aerobic fermentation of biofertilizer. There are two compost turners that are very popular with biofertilizer suppliers now.

Wheel type compost machine for large scale bio fertilizer composting

When you want to buy equipment for large scale biofertilizer composting, we recommend you choose our wheel type composter. Because it has a turning width of 10-30 m and a turning depth of 1-2 m. This makes it process more organic litter materials than other compost machines within a certain time. In addition, in order to help you finish biofertilizer fermentation quickly, we especially equip it with an electrically automatic control system. So without worker operation, it can move automatically along the rails on the sides of fermentation groove to process bio fertilizer compost.

Windrow compost turner for small scale bio fertilizer fermentation

Then if you want to make biofertilizer compost fertilizer in a small scale, we also can offer you windrow compost turner. It can process compost piles of a width of 2.4-3 m and a height of 0.6-1.5 m. That is, it can help you process 500-1500 ㎡ of biofertilizer per hour. In addition, it also has a characteristic of easy operation. Even a semi-skilled worker can drive to compost the large amounts of fertilizer windrows on the flat ground easily.

How to make bio fertilizer into granules?

In order to make biofertilizer easier to transport, store and sell, most biofertilizer plants prefer to process biofertilizer into pellets. For this, it is essential to buy suitable granulation equipment. Here, we recommend you choose the following two organic fertilizer granulation machines. New type organic fertilizer granulator or rotary drum pelletizer.

New type granulation machine for small scale bio fertilizer granulation

Provided you need a small scale granulation machine for biofertilizer processing, new type organic fertilizer granulator is an excellent choice for you. It has a capacity of 1-8 t/h, which can fully meet your requirements of small scale capacity. In addition, because it mainly relies on mechanical force of stirring teeth rotation to granulate bio fertilizer compost. The final biofertilizer pellets have a higher hardness, which makes it more convenient for use.

Rotary drum pelletizer for large scale bio fertilizer particles manufacturing

When it comes to large scale biofertilizer granulation, we recommend you choose rotary drum pelletizer. Using it, you can even prepare 30 tons of bio fertilizer granules an hour. Moreover, with designs of rubber lining, clean holes and lift plates, it can produce biofertilizer with less sticking. That is, longer service, less material waste and higher granule making efficiency.

What can you do to upgrade your bio fertilizer making line?

If you want to make bio fertilizer in a simple manner, you only need to buy compost machine and granulation equipment. However, provided you plan to upgrade this biofertilizer manufacturing system, you also need to purchase machines as follows:

Manure dewatering equipment

Dehydrator can help you reduce the moisture content of manure to 30%-50% quickly. So you can start bio fertilizer compost making better.

Batching machine

Batching equipment can feed raw materials according to your requirements. Therefore, you can produce biofertilizer according to local farming conditions.


Crusher is widely used in grinding agglomerated into fine powder. It is beneficial for the composting and granulation of biofertilizer production.


Mixer can help you mix various raw materials evenly. Which is the secret of preparing bio fertilizer with a balanced nutrient content.


Compost screener is designed to separate the biofertilizer you need from the unqualified. Then you can return the unqualified products to reprocess.

Dryer and cooler

Dryer and cooler can further remove excessive moisture from your granular bio fertilizer. So it can meet the international requirements of bio fertilizer water content (14%).

Coating equipment

Coating machine can add a protective film to your bio fertilizer pellets. Which can prevent sticking and nutrient loss.

Packaging machine

This is the final step of biofertilizer making. After processing with our automatic bagging machine, your can transport, store and sell your bio fertilizer in an easier way.
