Departing for Brazil! Cow Manure Fermentation Tanks

Today, a fermentation tank customized for a Brazilian customer was loaded onto a truck and will depart from Shanghai Port, crossing the Pacific Ocean to South America. This equipment, embodying Chinese manufacturing expertise, is specifically designed for large-scale agricultural waste treatment in Brazil. It will become a core component for the synergistic fermentation of sugarcane bagasse and livestock manure, injecting new impetus into South America’s agricultural circular economy.

As a major agricultural nation, Brazil generates vast quantities of agricultural waste, including sugarcane bagasse and coffee husks, annually. To address this challenge, the fermentation tanks feature an ultra-large volume (50 cubic meters per tank) and a twin-helix mixing system, ensuring uniform mixing of 80 tons of material per batch. This reduces the fermentation cycle to 10 days, a 40% increase in efficiency compared to traditional fermentation equipment. The tank’s interior is constructed of food-grade 316 stainless steel, resistant to corrosion from the high concentrations of organic acids in the bagasse, resulting in a service life of over 15 years.

The equipment has been specifically optimized for Brazil’s tropical climate. An intelligent ventilation system installed on the tank roof automatically adjusts the air exchange rate based on the internal temperature (55-65°C) to prevent the decline in microbial activity caused by high temperatures. A nano-insulation layer covers the outer wall, maintaining a stable fermentation temperature even at 35°C outdoors, reducing energy consumption by 25%. In-plant testing shows that the organic matter conversion rate of materials processed by this equipment reaches 85%, far exceeding the Brazilian organic fertilizer industry standard.

At the loading site, the logistics team implemented meticulous operations: the fermentation tanks are modularly packaged and smoothly loaded onto the truck using specialized lifting equipment. Vulnerable parts such as the agitator blades are individually custom-made shock-resistant wooden boxes with built-in cushioning. The electrical control system is moisture-proof and equipped with a humidity monitor to monitor the entire transportation environment. Included with the shipment is a Portuguese operating manual, 3D installation drawings, and a spare parts package worth $30,000, including seals, sensors, and other key components. “This fermentation tank will completely change our waste management model,” the customer’s representative stated at the loading ceremony. Their agricultural consortium processes 200,000 tons of sugarcane bagasse annually, and the inefficiency of the existing equipment resulted in a significant backlog of material. Once operational, the new equipment is expected to produce 12,000 tons of organic fertilizer annually for surrounding soybean plantations, reducing chemical fertilizer use by 30% and increasing annual revenue by approximately 2 million reais.

To ensure smooth delivery, we have partnered with agricultural machinery service providers in São Paulo, Brazil, to establish an after-sales network, promising a 72-hour response to repair requests and a 24-hour Portuguese technical hotline for remote commissioning support. Upon arrival, our engineers will be stationed to oversee installation, commissioning, and technical training.

This loading and delivery marks a significant milestone in China-Brazil agricultural equipment cooperation. We will continue to focus on the needs of the South American market, providing customized equipment and comprehensive services to help more countries realize the resourceful utilization of agricultural waste.
