Best Bio Composting Techniques You Must Know

Utilizing the aerobic fermentation technology, our compost machine promote organic waste into bio-organic fertilizer after high temperature decomposition. This process require optimizing control conditions such as temperature, moisture, PH value and C/N ratio. Moreover, you can apply the bio compost processed by our equipment directly to farmland soil or landscaping. Through deep processing, you also can make compost into organic fertilizer for sale in the market.

Aerobic fermentation is an exothermic oxidation and decomposition process in the presence of good ventilation effect and well-oxygenated conditions. Microbes oxidize part of the absorbed organic matter into simple inorganic matter through their own vital movement, releasing energy for microbial growth activities.

Another part of the organic matter is synthesized into new cytoplasm, so that microbes continue to grow and reproduce, resulting in the production of more organisms. Usually, aerobic composting has higher temperature, so it is also known as high-temperature composting.

Vertical Fermentation PotHorizontal Fermentation Pot

Horizontal & Vertical Fermentation Tank

Horizontal fermentation tank is a device to mix manure with auxiliary materials and strains and transport them to the tank, and then stir by the rotation of the tank, with aeration system for required oxygenation. The thermal energy generated by electric heating and the activities of microbial bacteria, accelerate evaporation of water and organic material transformation.

  1. The material reduction cycle is shorter.
  2. The horizontal fermenter is much less investment about comparing the vertical fermenter, and the energy consumption is relatively low.

  1. The fermentation cycle is quite short, and the moisture content is high after the treatment.
  2. The relative degree of harmless treatment is low.
  3. Material maturity is not stable, and it takes a long time to decay.

Vertical aerobic fermenter is becoming more popular as aerobic fermentation equipment. It needs to add auxiliary materials to reduce moisture, increase the carbon to nitrogen ratio, and then mix bacteria strains.

Because it is in a sealed state and the material thickness is substantial, it requires stirring and forced aeration to ensure oxygen and moisture evaporation required for aerobic fermentation, as well as auxiliary heat to promote the shortening of the fermentation cycle.

Large single-day processing capacity; independent choice of capacity models; lower labor costs; higher automation; odorless fermentation process.

This fermentation type has high input costs and auxiliary material expenses, as well as electrical power consumption.

What Are Control Conditions of Composting Periods?

The amount of oxygen supply should be appropriate, normally 0.1-0.2m³/min. The oxygen supply is by forced ventilation, and materials need to maintain certain space.

Typical materials’ moisture content regulation at around 65% is ideal.

A desirable PH value range for microbial growth is between 6.5 and 7.5 PH value can be adjusted by adding acid and alkaline auxiliary materials.

Aerobic fermentation of carbon and nitrogen ratio is appropriate in the range of 25:1 to 30:1.

The aerobic composting process should be accompanied by two temperature rises, which should be divided into three stages: the intial stage, the thermophilic stage, and the cooling stage.

Mesophilic bacteria decomposition of organic matter in easily degradable carbohydrates, lipids, etc., while releasing heat to raise the temperature, which can reach 50 ℃.

Under aerobic conditions, high temperature resistant bacteria multiply rapidly. Most of the difficult degraded proteins, fibre, and so on continue to be oxidized and decomposed, releasing a lot of heat energy, causing the temperature to rise to 50-60 ℃, with a maximum reaching 70℃.

When the organic matter is essentially decomposed, heat production then ceases. The temperature of compost gradually falls, and when it stabilized about 50℃, it essentially reaches stability and produces humus. After cooling, some new microbes emerge from the residual organic waste, and the composting process will be finalized.

What Does A Bio Composter Machine Do in fertilizer Production Process?

Composting serves a variety of purposes, including waste utilization, pollution reduction, soil improvement, yield enhancement, quality improvement, etc. Most importantly, it can transform a large amount of organic waste into useful products while reducing environmental risks. Moreover, it can create valuable compost products that can be used as soil conditioners or organic fertilizer products, etc.

During composting, compost turner stirs and entirely mixes with primary raw materials and a variety of auxiliary ingredients to modify the carbon-nitrogen ratio, PH value, water content, etc.

The compost turner makes direct contact with the raw materials and the air. Mixing promotes aerobic microbes’ active behaviors, and is conducive to a variety of beneficial microbial bacteria in their adaptation to temperature growth and reproduction.

The bio mechanical composting machine can handle the material in small clumps, transforming the stick characteristics and dense pile of raw materials into powder with the required porosity.

Through the bio composting process, you can control suitable moisture content of raw materials fermentation about 60%.

For example, crushing raw materials needs to shape them, or achieves their quantitative displacement.
