Aerodynamic Grain Dryers Metra—A Revolutionary New Level of Grain Cleaning

Grain crops form the backbone of North America’s agricultural sector as they play a crucial role in food production, exports, and livestock farming. The agribusiness sector fully meets domestic market needs and ranks among the world’s leaders in grain exports.

Carefully selected soils, adherence to agronomic best practices, and the use of modern equipment ensure high yields and premium grain quality. Metra’s aerodynamic grain dryers boost profitability and competitiveness for both small farms and large agribusiness holdings.

The Role of Modern Metra Grain Dryers in Agribusiness Development

Metra’s aerodynamic grain cleaning machines have driven a significant leap forward in the development of the agribusiness sector. The primary distinction of Metra’s machines is the combination of drying and cleaning functions within a single unit. Additionally, these machines are energy-efficient due to their innovative design—a highly efficient motor with direct airflow that minimizes air stream loss.

The Impeller Power Regulator handle allows for precise adjustment of the cleaning process for any type of grain, significantly reducing the machine’s setup time.

Major Challenge in Mechanical Drying and Cleaning

A critical problem with traditional mechanical drying and cleaning is grain damage. Whole, healthy grain can only be preserved using air separation—a sieving method where the grain mass is divided into fractions by an air stream. Traditional mechanical dryers push grain through rigid grids, causing damage. In contrast, air separation leaves the grain intact, significantly increasing the yield of seed material.

Airflow streams do not damage the grain and provide highly accurate calibration. The uniformity of grain kernels after air separation is approximately 98%.

The ability of Metra’s grain cleaners to separate grain by relative density allows for the effective removal of fungus-infected grains, including those affected by vomitoxin, fusarium, aflatoxin, and other harmful fungi that damage grain. Identifying grain diseases is difficult, and traditional separation methods are ineffective.

Unique and Versatile Design of Metra Grain Dryers

The unique construction of Metra’s grain dryers makes them universally effective for use across different types of farming operations. Small farms growing corn, soybeans, and wheat prefer Metra’s grain dryers as they boost the next season’s yield and significantly enhance grain quality.

Large agribusiness complexes involved in the procurement and processing of cocoa beans and coffee are also switching to Metra’s dryers to improve the quality of their finished products.

Metra aerodynamic grain dryers with cleaning functionality are a patented, one-of-a-kind invention based on aerodynamic principles. They use an air stream to accurately separate grain by relative density. Metra’s machines are capable of processing all types of grain, including:

• Wheat
• Oats
• Barley
• Corn
• Soybeans
• Lentils
• Hemp

Key Advantages of Aerodynamic Grain Dryers

1. Energy Efficiency

Metra’s aerodynamic grain dryers consume minimal electricity. It takes only 22 kWh to dry and clean 200 bushels per hour.

2. Mobility and Reliability

Metra’s simple design and innovative technology make their dryers essential assistants for farmers. The machines are lightweight, compact, and do not require special installation. They operate effectively both as stationary units and on the move.

3. Cost-Effectiveness

Metra’s dryers have no moving parts or lubrication points, meaning they experience minimal wear and tear. Notably, it is unnecessary to change screens for each type of grain. This boosts production efficiency by eliminating downtime for equipment setup. Switching from one grain type to another takes only 5-10 minutes.

4. Versatility

With high productivity and the ability to separate grains, Metra’s dryers can perform pre-cleaning, primary cleaning, and secondary cleaning simultaneously on a single machine. This also allows for the identification of the best seed material, optimizing sowing efficiency and increasing yields by up to 40% due to the uniform ripening of crops. The machines can clean and dry grain in a single pass.

5. Top-Level Service

Metra guarantees 24/7 technical support. Each machine is equipped with an intelligent system, allowing support staff to connect remotely for configuration adjustments and diagnostics, both before and after the harvest season.

6. Cyclone-Style Filtration

Metra’s grain dryers are equipped with a specialized cyclone filter that removes dust and pests, ensuring clean, healthy grain as the final product.

The company offers a broad selection of grain dryers and cleaning machines with processing capacities ranging from 200 to 8,000 bushels per hour, enabling each farm to choose the right solution for its needs.

Fast Detection of Diseased Grain

One of the standout features of Metra’s aerodynamic grain dryers is the integration of cutting-edge technology. The machines identify healthy grain and separate infected or pest-damaged kernels. Infected kernels often have no visual differences in color or size, making them impossible to detect with standard screen or color sorters. Metra’s machines also separate grains infected by any type of fungus, including vomitoxin (VOM), fusarium (FUS), and aflatoxin (AFLATOXIN). Grain is sorted by relative density, ensuring optimal germination and superior results.

Summary of Aerodynamic Grain Dryer Benefits

• Replaces a 2-3 unit processing line with a single machine
• Significantly reduces electricity consumption
• Preserves the integrity of grain
• Adapts to any type of grain
• Sold directly from the manufacturer at prices 25% below market rates

Metra’s aerodynamic grain dryers are the best solution for all grain processing challenges. With aerodynamic dryers from Metra, you can increase yield and boost the value of your grain crops.
