The Industrial Composting Machine: How It Works?

There are three main techniques utilized in industrial composting and each one requires different types of equipment. The three types are: aerated static pile composting, in-vessel composting and windrow composting.

Windrow composting is a completely open-air process, which requires large areas of outdoor space. The composting materials are places in long piles of around 5ft in height. The piles are called “windrows” and they require regular turning to ensure fast, complete fermentation. Regular turning means that all the composting materials get to spend time decomposing in the warmest part of the piles where the bacterial activity is at its highest. The open-air nature of windrow composting means it’s most suited for garden waste and backyard waste that does not produce strong odors. The type of industrial composting machine needed for windrow composting is a fully hydraulic compost turner.

In-vessel composting is carried out in an enclosed environment. The technique can process huge quantities of waste with smaller space requirements than the windrow method. Furthermore, it can be used to compost all types of organic waste including animal manure, food scraps, and bio-solids. The process involving feeding organic waste materials into a concrete-lined trench, drum, silo or industrial aerobic fermentation pot. The temperature, airflow, and moisture content can all be more easily controlled due to the contained environment of the decomposing waste. What’s more, to speed up the composting process, the waste can be mechanically mixed to increase aeration and encourage bacterial activity. The vessels used for in-vessel compositing vary in capacity depending on the needs of the industrial composting business.

The time it takes for in-vessel compositing varies from weeks to months depending on the nature of the waste materials. Sufficient time is needed to allow the compost to cool down after microbial activity has ceased. Temperature probes are used to ensure the temperature of the piles reaches 140 degrees Fahrenheit for at least two consecutive days. This is necessary to guarantee that all dangerous bacteria are killed.

The aerated static pile composting process produces compost slowly. The process generally takes around three to six months. The method is ideal for composting homogenous mixes of organic waste and is commonly utilized by municipal waste processing facilities. To ensure the piles of waste are sufficiently aerated, layers of loosely packaged bulking agents, such as shredded paper and wood chips, are added.

Industrial composting is about more than just producing high-grade soil fertilizers for the agricultural sector; it also helps to deal with mounting waste disposal problems around the globe. It is one of the most environmentally friendly ways to process municipal waste like soiled paper, bioplastics, food scraps, yard trimmings, etc. With an industrial composting machine, it possible to process tens of thousands of tons of organic waste each year.

The cost of industrial composting machines varies depending on the method of composting being adopted by a business. If you are interested in investing in composting machinery, it’s important to determine the function, capacity and processing mechanisms required for your business.

Benefits of Using Cow Dung Powder Fertilizer Production for Agricultural Application

It is an age-old tradition to use cow dung in the garden. Most farmers use fresh cow manure in their fertilizers to improve crop production. But, fresh cow dung contains high levels of ammonia. This usually leads to plants dying when the farmer applies the manure directly. That is why modern farmers use cow dung powder instead of the raw product. They provide a lot of benefits that other types of manure may not offer.

Components of cow dung powder

Cow dung powder is a combination of many things. Although the dung consists of digested grains and grass, the powder used for fertilizer production goes through a composting process. Cow dung contains approximately 1% potassium, 2% phosphorus, and 3% nitrogen. Apart from these three essential elements, it also has a high percentage of ammonia that is harmful for pathogens. That is why farmers use composted cow dung so that it doesn’t contain the harmful ammonia gas.

Functions of cow dung powder for agricultural applications

Composted cow dung powder adds a significant amount of organic matter in the soil that promotes crop growth. It increases the moisture-holding capacity of the soil. So, farmers will need to water their crops less frequently. Countries that have scarce water supply use cow dung powder fertilizers so that they don’t have to rely heavily on water. The roots of the crop use additional nutrients and water whenever required.

In addition to increasing moisture-holding capacity, cow dung powder fertilizer which produces by cow dung powder making machine also improves soil aeration. It breaks down the compacted soils and increases porosity, allowing the crops to grow quickly. The healthy bacteria present in this type of fertilizer converts nutrients to different accessible forms that release the essential minerals slowly and steadily without burning the tender crop roots.

Composting cow dung powder

Cow dung powder is not only used in the fertilizers but also spread as a top dressing on crop soil. This nutrient-rich fertilizer is appropriate when it comes to producing fresh crops at the start of the growing season.

The composting process starts by collecting cow dung and mixing it with relatively lighter materials, such as hay or straw. Some of the other ingredients used in the compost mix are ash, lime, garden debris like leaves and twigs, and vegetable matter. Most manufacturers produce mass-scale cow dung fertilizer by self propelled compost turner or cow dung powder production line. So, they need sufficient space to allow the pile to get enough air.

Many farmers who need cow dung powder fertilizer in small quantities can make the same in their house. Since it doesn’t require too much heat, the farmer can keep the manure under a shade and keep twisting and turning it to provide air. On the other hand, manufacturers producing this fertilizer in large quantities use composting machines that mix the ingredients in equal quantities. They can control the temperature and also twist and turn the manure periodically.

This is one of the most inexpensive fertilizers in the agricultural sector. But, it helps to produce a high-quality crop, and that’s why most farmers use it widely all over the world.
