The entire process of organic fertilizer production in agriculture

Organic fertilizer production is an ecological cycle of “turning waste into treasure.” Organic fertilizer production lines transform agricultural waste into nutrients that nourish the soil, and the entire process is guided by a green and environmentally friendly philosophy.

The first step in production is the collection and mixing of raw materials. Common raw materials include plant residues such as crop straw, rice husks, and peanut shells, as well as livestock manure such as chicken, cow, and sheep manure. These raw materials must be strategically combined to achieve a carbon-to-nitrogen ratio of approximately 30:1, for example, a straw-to-manure ratio of approximately 3:1. A small amount of wood ash is added to adjust the pH and create a suitable environment for microbial activity.

Next, the fermentation and composting stage begins, the core of organic fertilizer production. The mixed raw materials are transferred to a fermentation silo where they are regularly stirred by a turning device to maintain a temperature of 55-65°C. This temperature not only kills pathogens, insect eggs, and weed seeds, but also stimulates microbial activity. After 20-30 days of composting, the raw materials will gradually darken and soften, emitting a faint earthy odor, indicating that the organic matter has been fully decomposed.

The composted material needs to be refined. First, it is crushed into a fine powder by a crusher to remove impurities and large particles. Then it enters the granulation stage, where a granulator is used to make the powder into granules with a diameter of 2-5 mm for easy storage and application. Finally, it is screened by a screening device to separate the qualified granules, and the unqualified crushed materials are returned for reprocessing.

The finished product also undergoes quality inspection, testing for organic matter content, pH, and heavy metal content to ensure compliance with national standards. Qualified organic fertilizer granules are uniform, have a moderate moisture content (approximately 20%), and slowly release trace elements such as nitrogen, phosphorus, potassium, and calcium and magnesium.

The entire production process utilizes agricultural waste as a resource, addressing environmental pollution while replenishing natural nutrients to the soil. This “take from the field, return to the field” model is the key to the sustainable development of organic agriculture.

How to Choose the Right Double Roller Press Granulator for Farms

Due to its unique advantages, double-roller press granulators have become essential equipment for farms to process manure and produce organic fertilizer. When selecting a granulator, you need to consider multiple factors to ensure it meets your production needs.

First, you need to determine your production scale. Small and medium-sized farms have limited daily manure processing capacity, so choosing a small machine with an hourly capacity of 1-3 tons can meet daily granulation needs while avoiding idle equipment. Large-scale farms require a machine with an hourly capacity of 5 tons or more and strong continuous operation capabilities to ensure timely manure processing and stable fertilizer output.

Second, consider the characteristics of the raw materials. Farms primarily use livestock and poultry manure as their raw material, which is high in moisture and contains impurities such as crude fiber. Therefore, the equipment needs to have strong anti-clogging capabilities, and the roller surface should be made of a non-slip and wear-resistant material to prevent slippage and affect granulation efficiency.

Supporting facilities should be planned simultaneously. It’s recommended to use pre-treatment equipment such as dewatering machines and crushers to control the moisture content of raw materials within an appropriate range, and to configure screening devices to grade finished particles to improve fertilizer quality. Furthermore, consider equipment energy consumption, prioritizing energy-efficient models to reduce operating costs.

A balance should be struck between price and after-sales service. Avoid blindly pursuing low-priced equipment, as its materials and workmanship may be defective and increase maintenance costs. Choose a manufacturer that can provide installation and commissioning, operator training, and rapid fault response to ensure stable operation after the equipment is commissioned and minimize losses caused by downtime.

A comprehensive assessment of production scale, raw material characteristics, equipment quality, supporting capabilities, and after-sales service is crucial to selecting a double-roller press granulator suitable for your farm, ensuring efficient resource utilization of manure.
