What equipment does it take to turn food waste into organic fertilizer

Technology to turn food waste into organic fertilizer

Composting can bring a variety of environmental benefits, including reducing water pollution, and the economic benefits for farmers, gardeners and landscape architects are huge.

◆Dehydratio

Water is the basic component of food waste, accounting for 70-90%, and is the basis of food waste spoilage. Therefore, dehydration has become the most important part of the process of food waste conversion to organic fertilizer.

Food - kitchen waste treatment plant is the ideal equipment for processing food - kitchen waste. It mainly includes: sieve dehydration system → feeding system → automatic sorting system → solid-liquid separator → oil-water separator → composting machine in container. The basic process can be divided into flow parts:

1. Food waste must be pre-dehydrated first, as it contains too much swill.

2. Classify the inorganic waste in food, such as metal, wood, plastic, paper, fabric, etc.

3. After sorting, the kitchen waste is sent to the spiral solid-liquid separator for crushing, dehydration and degreasing.

4. The extruded kitchen waste shall be dried and sterilized at high temperature to remove excess moisture and various pathogenic microorganisms. To achieve the required fineness and dryness of compost, and can be directly fed into the pot composter through the belt conveyor.

5. The water removed from food waste is a mixture of oil and water separated by an oil-water separator. The separated oil is further processed into biodiesel or industrial oil.

◆Compost

The pot compost is a kind of completely enclosed fermenter which adopts high temperature aerobic fermentation technology. The rapid composting process of the container composting machine produces superior compost that can be more tightly controlled, leading to faster decomposition and more consistent product quality.

The odorless and aseptic organic manure produced by composting machine not only saves landfills, protects the environment, but also produces certain economic benefits.

◆Granulation

Particulate organic fertilizers occupy an important position in the fertilizer supply worldwide. The key to improve the yield of organic fertilizer is to choose the appropriate organic fertilizer granulator. Granulation is the process of material formation of small particles, it improves the technical performance of the material, prevent caking, increase flow performance, make the material dosage is small, easy to load, transportation and so on. All raw materials can be made into round organic compost by our organic compost granulator. The granulation rate of the material can reach 100% and the organic content can reach 100%.

◆ Drying and cooling

Rotary drying and cooling machines are often used in organic fertilizer production lines. Remove the moisture of organic fertilizer, reduce particle temperature, to achieve the purpose of sterilization and deodorization. These two steps minimize nutrient losses in organic fertilizers and produce smoother boundaries.

◆ Check and package

The screening process is to separate the unqualified granular fertilizer, which is completed by the drum screen machine. Unqualified granular fertilizer sent to reprocessing, qualified organic fertilizer with automatic packaging machine packaging.

The benefits of organic food waste:

Converting food waste to organic fertilisers brings economic and environmental benefits that improve soil health, help reduce erosion, and improve water quality. Similarly, renewable natural gas and biofuels can be produced from recycled food waste, using them to help reduce our dependence on greenhouse gas-intensive fossil fuels.

By composting food waste you don't need, you're providing energy to the soil for the plants of the future. High-quality organic fertilizers will be used for a variety of purposes, including agriculture, local farms and flower displays in public Spaces. Organic fertilizers are the best nutrients for the soil and have many benefits for the soil. It is a good source of nutrients for plants, including nitrogen, phosphorus and potassium, as well as micronutrients, which are essential for plant growth. It can control some plant diseases and also reduces the need for various fungicides and other chemicals.
