Industrial Composting Machine

Along with the development of modernization, people pay more attention to environment protection and green living. Composting becomes an efficient way to deal with large amount of organic waste. Industrial composting is often used for dealing with plenty of municipal sludge and food waste. The disposal of organic waste will occupy much space and may pollute environment. But the volume of organic waste will decrease by composting. And odor will disappear. What’s more, composted organic waste can become high-quality organic fertilizer, which can provide nutrients to plants. Therefore, it is a good way to adopt industrial composting on disposing city garbage. Generally speaking, the size of organic waste for industrial composting is large. So, it is necessary for you to adopt industrial composting machine. In terms of raw material, industrial composting process, system, composting equipment and design, we will provide detailed instructions bellow.

What kind of organic waste can be used for industrial composting?

Industrial composting usually refers to disposal of a lot of waste from city. And industrial composting dedicates to convert useless organic waste into nutrient-rich organic fertilizer. Besides landfill, many organic wastes can be recycled by composting. And the common waste includes:

  • Large amount of food waste from restaurants and residential area
  • Grass, leaves and tree branches from urban landscaping
  • Animal manure from zoo and pets

What is industrial composting process?

In order to convert organic waste into organic fertilizer by industrial composting. Firstly, you should collect the main raw material. Here we can make food waste composting as an example. You should periodically collect food waste from places, where have no solution on food waste disposal. At the same time, you can also collect dried leaves, lawn clippings, spent plant matter from the garden, used newspaper and straw. Because they can provide carbon and nitrogen, which can accelerate composting speed. Second, you can start to pre-treat the waste. For organic waste with high water content, you should decrease its moisture to 55% by solid liquid separator machine. In addition, you need to crush garden waste into pieces by straw crusher. Because too large size will influence fermentation speed and results. Finally, you can stack the waste together, and turn them regularly, so as to maintain good fermentation conditions.

Industrial composting systems

As mentioned above, you can start composting after collection and treatment of organic waste. There are three kinds of industrial composting system for you to reference. Windrow composting, groove type composting and composting with aerobic fermentation pot. And then we will introduce them separately.

Windrow composting

In terms of this system, you should stack organic waste on the ground by taking form of windrow or strip. On the one hand, the site you choose should be far away from residential area, due to odor produced in composting. On the other hand, you should build a roof for these compost piles. Because rain, snow and other bad weathers may cause adverse effect on composting period.

  • Capacity: 1500-1800 cubic meters/h
  • Color: Dark green (can be customized)
  • Application: Turning organic waste during composting

Groove type composting

Like windrow composting, groove type composting also needs large space. But the difference is that you should build some paralleled grooves to place organic waste. And the number of grooves depends on the amount of organic waste. What’s more, the fermentation groove not only can preserve heat during fermentation, but also store more organic waste than windrow composting under the same space.

Composting with aerobic fermentation pot

In view of odor from organic waste, aerobic fermentation pot is one of best industrial composting machines. Aerobic fermentation pot belongs to closed and aerobic composting equipment. The features of fermentation pot is space-saving, high output and short composting period. It can shorten fermentation period to 7-10 days. In addition, fermentation can effectively deal with odor by deodorization system.

In a word, these three industrial composting systems can finish composting with high efficiency. And you can choose the most suitable one, according to your actual requirements.

Industrial compost bin

Industrial compost bin is aerobic composting equipment. When you finish pre-treatment of organic waste, you can send them into industrial compost bin. Then, this equipment can automatically adjust fermentation conditions, such as temperature, oxygen content and moisture. The stirring apparatus inside compost bin will stir the organic waste regularly, so as to make thorough fermentation. At the same time, air system will send air to organic waste. The air supply not only can guarantee sufficient oxygen, but can prevent too higher heat in the fermentation pot. Finally, the composting period will be finished in 7-10 days. The deodorization system will deal with odor and exhaust harmless gas. Then you should place compost together for several days before application, so as to guarantee its stability and security.

Granulating equipment for granular organic fertilizer production

After composting, organic waste has become compost with the help of industrial composting machine. And then you can deeply process it by granular organic fertilizer production line. The purpose of granulating is to make fertilizer powder into pellets, which is more convenient for storage and transportation. In this process, Tongda granulating equipment adopts wet granulation to make fertilizer pellets. Moreover, there are new type organic fertilizer granulator, pan granulator and rotary drum stirring granulator. All of them are high-efficiency granulator, whose granulating ratio is above 93%. With the help of stirring force or centrifugal force and steam, fertilizer powder becomes compact pellets. After this, you may need to dry them by fertilizer drying machine, so as to decrease fertilizer’s moisture and extend storage time.
