Granulation Production Line: Transform Food Waste to Organic Fertilizer

Plant to Convert Food Waste to Bio-Organic Fertilizer

Introduction for Plant to Convert food waste to Bio-Organic Fertilizer
The organic fertilizer Granule production line project with an hour output of 5ton planned by our company is a process of producing organic fertilizer by granulating organic waste after microbial fermentation. It is a high-tech project with significant economic and environmental benefits. At the request of your company, this plan is specially formulated for reference.

Technical Process for Plant to Convert food waste to Bio-Organic Fertilizer
The entire production line is mainly used to process materials (cow dung, sheep dung, pig dung, chicken dung, sludge, rice straw, corn straw) and other animal manure organic waste after fermentation and decomposing, which contains about 30%-35% moisture content. After crushing and sieving, the binder (bentonite, humic acid) and other ingredients that need to be proportioned are measured in the batching mixing system according to the proportioning requirements. (Adding functional bacteria can produce biological organic fertilizer, adding nitrogen and phosphorus , Potassium (the total nutrient content is less than 15%) can produce organic and inorganic fertilizer) dosing, mixing, the fully mixed material is uniformly and continuously fed into the granulator by the belt conveyor, and then rounded into spherical particles by the polishing and shaping machine. After drying at low temperature and high air volume by dryer (≤65ºC), it is cooled and sieved. The finished particles are conveyed to the finished product silo by belt, and are measured and packed into storage by the computerized quantitative packaging system.

Description for Plant to Convert food waste to Bio-Organic Fertilizer

3. The reducer adopts the national standard heavy duty;
4. The materials and equipment involved in this plan must be manufactured in accordance with the requirements of the national standard;
5. All configurations required in this technology are included in the total quotation;

How to Produce High Quality Organic fertilizer?
1st Step: De-watering process to low the moisture of the raw materials to be 50-60% by using De-watering machine or mixing dry grass or straw powder;
2nd Step: To mix the biological fermentation bacteria agent with the raw materials by using Wheel Loader or Forklift (we can provide the technology and fermenting bacteria agent.);
3rd Step: Aerobic fermentation by using Compost turner (Mobile type and Fixed type);
4th Step: Crushing the fermentation cake by using Single-level or Double-Level Vertical crusher or Horizontal crusher;
5th Step: Separating the crushed ready compost by using the Rotary Drum Screener;
6th Step: Mixing with other required components by using the Double-Shaft Mixer or Single-Shaft Mixer;
7th Step: Packing the ready powder organic fertilizer by the Packaging machine;

Till now, we already get the qualified powdery organic fertilizer. If you need to produce the granule or pellet fertilizer, we can do as below steps:

8th Step: Granulating or Pelletizing the powder fertilizer by using Disc Type Granulator, Rotary Drum Granulator, Organic-Compound Drum Granulator, Double Roller Granulator, Flat die Pellet mill, Ring Die Pellet mill;
9th Step: Drying the ready granule or pellet to be correct moisture depending on the different customers` requirements by using the Rotary Drum Dryer;
10th Step: Separating the different size Granular or pellet as different customers` requirements by using the Rotary Drum Screener;
11th Step: Cooling the separated granular or pellet bio-organic fertilizer by using the Rotary Drum Cooler;
12th Step: Coating the cooled granular or pellet bio-organic fertilizer by using the Rotary Coating machine, the coat can be dry powder or liquid;
13th Step: Packing the ready granule or pellet organic fertilizer by the Packaging machine;
14th Step: Palletizing the bags on the pallets by using the Palletizer.
