The 500kg Automatic Corn Thresher is a fully automated machine designed for efficient separation of corn kernels from cobs. With a high-throughput capacity (500kg/hour) and precision engineering, it streamlines corn processing in agricultural cooperatives, food factories, and biofuel plants. This thresher integrates advanced technology to minimize kernel damage (<2%) and maximize yield, while separating cobs for secondary processing (e.g., animal feed, biomass pellets).

Stainless steel material
Equipped with a 2-meter-long infeed conveyor integrated with an optical sensor, the machine detects cob density in real-time. This smart technology adjusts the feeding rate automatically to prevent overloading, ensuring consistent performance and reducing the risk of mechanical strain. The seamless feeding process eliminates bottlenecks, allowing for uninterrupted operation.
At the core of the machine is an 800mm-diameter rotating drum fitted with rubber-tipped steel fingers. The drum’s speed is adjustable between 800-1200 RPM, enabling operators to optimize kernel separation based on corn variety (e.g., fresh, sweet, waxy, or thawed corn). This flexibility ensures high efficiency across different corn types, making the thresher versatile for diverse processing needs.
A built-in centrifugal fan with adjustable airflow (500-1000 m³/hour) effectively removes husks, dust, and lightweight debris from the kernels. This ensures the output is clean and ready for further processing, reducing the need for additional cleaning steps and saving time in the production line.
A vibrating sieve with 3mm and 5mm screens separates whole kernels from fragments, directing them to separate outlets. This feature enhances product quality by ensuring uniform kernel size, which is crucial for food processing applications where consistency matters.
The machine includes a dedicated conveyor system for automatic cob removal. For added convenience, an optional chopper attachment is available to reduce cobs to 50mm lengths, simplifying their handling and storage for secondary uses.

Processing 500kg of corn per hour, this thresher reduces labor costs by up to 70% compared to manual threshing or semi-automatic machines. Its automated design minimizes human error and downtime, ensuring consistent productivity even during peak processing seasons.
The precision threshing drum and adjustable speed settings protect kernel integrity, keeping damage below 2%. This preserves the market value of food-grade corn, making it suitable for sale as fresh produce, canned goods, or processed ingredients.
Powered by a 7.5kW motor with a soft-start function, the machine consumes 30% less energy than traditional threshers. It also features energy recovery from cob compression, further reducing operational costs over time.
Built with a heavy-duty steel frame and wear-resistant components, the thresher is designed to withstand 10,000 hours of continuous operation. This longevity ensures a strong return on investment for businesses looking to expand their processing capabilities.
Meeting ISO 22000 food safety standards and CE directives, the machine is safe for use in regulated environments, ensuring compliance with local and international industry regulations.
Whether you’re processing corn for food, feed, or biofuel, the 500kg Automatic Corn Thresher Cob Production Line delivers efficiency, quality, and versatility—making it a must-have for modern agricultural and food processing operations.
