How does a manure composting machine improve fermentation odor?

2025-07-15

Composting is a good way for farms to deal with manure. However, the foul smell emitted during manure composting will not only be complained by surrounding residents, but will even face fines for failing to meet environmental protection standards. Traditional composting faces the problem of “the more it piles, the more it stinks”.

 

At present, with the development of technology, professional sealed composting tank for manure fermentation have been created, which can not only solve the deodorization problem, but also turn waste into treasure. But among many suppliers, which one should we choose? As a leading manufacturer of manure composting machine, Bolong will provide you with the most appropriate solution.

 


 

Why is it difficult to ferment manure?

 

Three major sources of odor removal

 

  • A large amount of organic matter:  Manure contains a large amount of organic matter, such as protein, sulfur-containing compounds, etc. When they are decomposed by microorganisms, they will produce ammonia, hydrogen sulfide and other gases with strong irritating odors. When the concentration is too high, it will cause respiratory discomfort.
  • Fermentation environment out of control:   Traditional composting is mostly open or semi-open fermentation. Fermentation conditions such as oxygen and temperature are unstable, which can easily lead to anaerobic fermentation environment, faster biological reproduction, and more odorous gases, resulting in more and more odor.
  • No protective measures:  Without sealing measures, odorous gases are directly discharged into the air, and the odor spreads more widely.

How can a manure composting machine achieve efficient deodorization?

 

Source control and terminal deodorization

 

  • Source control:  Bolong’s sealed composting tank for manure fermentation adopts a vertical closed tank design. The seamless welding process prevents gas leakage. The fermentation process is not in contact with the outside world, cutting off the possibility of odor diffusion from the source.
  • Terminal deodorization:  The standard heat exchange deodorization device is equipped with a spray tower, which uses the characteristics of ammonia being easily soluble in water to significantly reduce the ammonia concentration. The deodorization efficiency is more than 95%, which meets the national emission standards.

 

The anti-corrosion stainless steel composting tank for persistent odor problems uses the principle of high-temperature aerobic fermentation to monitor fermentation conditions in real time, promote the efficient reproduction of aerobic microorganisms, inhibit anaerobic odor-producing bacteria, and reduce the generation of odorous gases from the fermentation process. The Bolong composting machine manufacturer must be your only choice.

 


 

What is the use of livestock manure after composting?

 

The manure that has been decomposed by Bolong’s sealed composting tank for manure fermentation has a high organic matter value. Compared with traditional organic fertilizers, the eggs and bacteria in it are killed and can be directly used for farmland fertilization to improve soil fertility. Crops grown in the same farmland grow better when composted manure is applied, and organic fertilizer can also be sold to the outside for additional income, or used in its own planting base to reduce planting costs.

 

Bolong manure composting machine is also an industrial-grade composting tank for large-scale farm waste odor elimination. It has solutions that meet a variety of processing volumes. The 7-day rapid decomposition technology reduces the fermentation cycle while ensuring that the manure is fully fermented, which meets the organic fertilizer industry standards.

 


 

Benefits to Farm Enterprises

 

  • Environmental compliance:  The deodorization effect of Bolong manure composting machine has been tested by a third party and has met the standards, avoiding penalties for excessive odor and solving complaints from surrounding residents.
  • Cost reduction and efficiency improvement:  The sealed composting tank for manure fermentation adopts an intelligent control system, which is easy to operate and saves manpower; at the same time, it can also increase income through the sale of organic fertilizer.

 


 

Right manure composting machine eliminates odors, boosts profits

 

The odor of manure fermentation is difficult to remove. The root cause is that good measures have not been taken to control odor. Professional manure composting machines use multiple means to deodorize. Bolong’s industrial-grade composting tank for large-scale farm waste odor elimination are the preferred options.
