Mobile Grain Dryer User Guide

With the modernization of agriculture, mobile grain dryers have become an important tool for farmers to cope with humid weather and reduce post-harvest grain losses. Jinlu Machinery will provide detailed instructions on how to use this convenient equipment correctly.

During the harvest season, weather fluctuations are often a major concern for farmers. Traditional drying methods rely entirely on weather conditions. If there is continuous rain or overcast weather, the grain is prone to mold and mildew, resulting in significant losses. The emergence of mobile grain dryers has completely changed this situation.

01 Equipment Features and Advantages

The most significant feature of mobile grain dryers is their ease of mobility. Equipped with heavy-duty tires and a traction device, they can be towed directly to the fields by a tractor, enabling “wherever needed” operation.

Compared to traditional fixed drying equipment, mobile dryers offer advantages such as low investment, flexibility, and ease of operation, making them particularly suitable for small and medium-sized farms and individual farmers.

02 Detailed Instructions for Use

① Preparation

Before use, check that all equipment components are in good condition, confirm that the power supply lines are secure, and clean debris and dust from inside and outside the equipment. At the same time, measure the initial moisture content of the grain to be dried and sort grains with similar moisture content into batches for processing.

② Loading Techniques

Place the grain evenly in the dryer, taking care not to overfill or crowd it. This ensures that the hot air can evenly pass through the grain layers, ensuring consistent drying results.

③ Temperature Control

Adjust the appropriate drying temperature based on the grain type and initial moisture content. Generally, the drying temperature should be kept between 50-70°C. A temperature too high will affect grain quality, while a temperature too low will result in poor drying efficiency.

④ Drying Process Monitoring

Regularly check the moisture content of the grain during the drying process. Typically, sample grain from the sampling port every 20-30 minutes for moisture testing. Observe the equipment’s operating status to ensure proper operation.

⑤ Completion and Maintenance

Once the grain reaches the safe moisture content (generally below 13%), stop heating and allow the equipment to cool before turning off the fan. Clean the equipment promptly after use and perform regular maintenance.

⑥ Precautions

When using a mobile grain dryer, pay special attention to fire safety. Flammable items should not be stored around the equipment. At the same time, ensure the equipment is placed stably to avoid movement during operation. Different grain varieties require different drying parameters. When using the equipment for the first time, refer to the equipment manual or consult a technician.

⑦ Economic Benefit Analysis

The use of mobile grain dryers can effectively reduce post-harvest grain losses. Based on my country’s average post-harvest grain loss rate of 8%-12%, using a dryer can reduce this rate to below 2%, resulting in significant economic benefits. Furthermore, by eliminating the manual turning and collecting required for traditional drying, labor intensity is significantly reduced and work efficiency is improved.

As a vital piece of equipment in modern agriculture, mobile grain dryers are solving grain drying challenges for farmers. Proper use and maintenance of the equipment not only ensures grain quality but also generates substantial economic benefits. With continued technological advancement, this equipment will play an even greater role in sustainable agricultural development.
