The customer from Iran

Contenu

Biogas residue is a high-quality raw material for making organic fertilizer. En mars 28, 2025, we received an inquiry from a customer in Iran. "I have a biogas system fed with cow manure, and I want to manage the digested waste in a way that ensures the quickest possible return on investment." After thorough communication, we offered him a customized powdered fertilizer production solution based on digestate as fertilizer. This approach focuses on low investment, fast processing, and quick market entry. Below are the details of our project discussion.

Is It Possible to Turn Digestate into Fertilizer with Low Cost and Fast Payback?

The customer in Iran is looking for a fast and cost-effective way to profit from digestate as fertilizer. Producing powdered biofertilizer is a smart solution. The process is simple and requires relatively low investment.

  • D'abord, dewater the digestate, as its high moisture content is unsuitable for further processing.

  • Alors, mix in straw powder, fermentation agents, and adjust the pH and C/N ratio to optimize composting conditions.

  • Suivant, carry out aerobic composting to eliminate pathogens and stabilize the material.

  • Après le compostage, screen the material to remove impurities, then crush it into fine powder.

  • Enfin, you can blend microbial agents in a mixer and package the finished powdered fertilizer into various sizes for market.

Main Equipment Provided by YUSHUNXIN for the Iranian Customer

Based on the above customer's production plan, YUSHUNXIN supplied the following key equipment:

Screw press dehydrator reduces the moisture content of biogas residue to around 25%, ensuring a high separation efficiency between biogas slurry and solid residue. It significantly improves the material's suitability for composting.

For efficient aerobic composting, we recommended a crawler-type compost turner. It offers two major advantages: Excellent mobility on various terrains, helping reduce site construction costs; High turning capacity for fast, uniform fermentation of digestate.

The machine help separate clumped materials and achieve the desired size for powdered biofertilizer. Made of galvanized steel, the screen is highly durable and corrosion-resistant.

Since the customer wanted to add nitrogen-fixing and compound microbial agents, we suggested adding them after crushing. Le mélangeur à arbre ensures thorough and efficient blending, maintaining microbial viability.

This crushing machine is essential for producing fine powdered fertilizer from digestate. It features a compact structure, fast crushing speed, and adjustable settings to deliver consistent powder quality with high efficiency.

For final packaging, le single-bucket bagging unit enables quick and accurate filling of finished products into 25kg, 50kg, or 100kg bags, ready for sale.
