LONGWELL Axial Flow Fans Boost Energy Efficiency in Brazil’s Poultry Farming Industry
🐔 Challenge Context: Farming Dilemmas in a Tropical Climate
On the tropical plains of Brazil, a large integrated broiler farming enterprise was facing new challenges. High temperatures, humidity, and stagnant air were subtly affecting the growth efficiency and health of the chicken flock. Traditional ventilation systems struggled to maintain a constant temperature, leading to high energy consumption and increased mortality rates. To address this problem, they turned to Ningbo Longwei Electric Co., Ltd.—LONGWELL.
At the start of the project, the LONGWELL engineering team traveled to the site for an in-depth analysis of the chicken house structure, airflow distribution, and climatic characteristics.
Location: Tropical plains of Brazil (A large integrated broiler farming enterprise)
|
Pain Point |
Description |
|
High Temperature and Humidity |
External temperatures reached up to $35\text{°C}$, with severe air stagnation inside the chicken house. |
|
Low Efficiency |
Chicken growth efficiency was affected, and the average weight was difficult to increase. |
|
High Mortality Rate |
Traditional ventilation systems failed to maintain a constant temperature, resulting in persistently high mortality rates. |
|
High Energy Consumption |
The traditional system had low operating efficiency and consumed a huge amount of electricity. |
💡 LONGWELL Solution: Tunnel-Type Smart Ventilation
Ultimately, LONGWELL customized a tunnel ventilation system solution for the enterprise, comprising high-performance axial flow fans. Each chicken house was equipped with multiple LONGWELL external rotor axial flow fans, combined with an automatic temperature and humidity control system, enabling intelligent, partitioned management.
· Core Product: LONGWELL High-Performance External Rotor Axial Flow Fans
· System Components:
1. Tunnel Ventilation System: Utilizes multiple large-air-volume axial flow fans to achieve rapid and uniform air exchange.
2. External Rotor Motor Design: Features a compact structure, high efficiency, and stable long-term operation.
3. Smart Control: Combines with an automatic temperature and humidity control system to realize partitioned and intelligent management.
During the day, the Brazilian sun is scorching, with external temperatures reaching $35\text{°C}$. However, with the continuous operation of the LONGWELL axial flow fans, the airflow inside the chicken house remained smooth and the temperature distribution was uniform. Factory Manager Carlos stood in the center of the chicken house, feeling the cool airflow, and smiled, saying: “Before, we hardly dared to enter the chicken house in the afternoon, but now it’s still comfortable inside, even when it’s scorching hot outside”.
📊 Project Results Highlights
After three months of system operation, the data feedback was surprising:
During the 42-day market-ready cycle,
· the average weight gain per chicken increased by 150 grams, raising the weight from 2.3 kg to 2.45 kg.
· The mortality rate dropped from $4.5\%$ to $1.8\%$.
· The annual economic benefit increased by approximately R$850,000.
· The Return on Investment (ROI) was achieved in 18 months.
· The enterprise successfully passed the Global G.A.P. Poultry Certification, becoming a demonstration base for green farming in the area.
