The Need for Automatic Soybean Seed Dryers

Oct 13, 2025 by thesweetdesigns.com 108 views

Introduction

Soybean is one of the most important food sources in Indonesia, and maintaining its quality is crucial for producing high-quality food products. However, traditional drying methods used by farmers have several limitations, including dependence on weather conditions, inability to monitor water content, and the risk of depreciation due to grain-eating animals. Therefore, innovation is needed in the form of an automatic dryer that can overcome these problems.

The Need for Automatic Soybean Seed Dryers

Traditional drying methods used by farmers have several deficiencies, including:

Dependence on weather conditions: Drying is often done naturally, which means that it is dependent on weather conditions, such as temperature and humidity.
Inability to monitor water content: Farmers have no way of monitoring the water content of the soybean seeds, which can lead to over-drying or under-drying.
Risk of depreciation due to grain-eating animals: Grain-eating animals can damage the soybean seeds, leading to a loss of quality and quantity.
Lack of cleanliness guarantees: Traditional drying methods often do not provide a clean and safe environment for drying soybean seeds.

Design and Development of Automatic Soybean Seed Dryers

To overcome these limitations, an automatic soybean seed dryer was designed and developed using the ATmega328 microcontroller. The prototype utilizes several important components, including:

DHT22 sensor: This sensor measures temperature and humidity levels, allowing for automatic setting of temperature and humidity levels.
LCD screen: The LCD screen displays the data obtained from the sensor, providing clear information to farmers regarding drying status.
Relay: The relay is used to control the heating element, allowing for automatic temperature control.
Lights and Fans: The lights and fans are used to provide a clean and safe environment for drying soybean seeds.
Buzzer: The buzzer is used to provide warning sounds when the drying process is complete or when there is an error in the system.

Working Principle of the Automatic Soybean Seed Dryer

The working principle of the automatic soybean seed dryer is as follows:

Temperature and Humidity Setting: The DHT22 sensor measures temperature and humidity levels, and the microcontroller sets the temperature and humidity levels based on the farmer's preferences.
Heating Element Control: The relay controls the heating element, allowing for automatic temperature control.
Data Display: The LCD screen displays the data obtained from the sensor, providing clear information to farmers regarding drying status.
Warning Sounds: The buzzer provides warning sounds when the drying process is complete or when there is an error in the system.

Testing and Analysis

The automatic soybean seed dryer was tested using soybean seed samples, and the results showed that the humidity level of the seeds could be reduced by up to 14%. The test analysis showed that the use of this tool not only increases the efficiency of drying but also improves the quality of the soybean seeds produced.

Conclusion

The manufacture of soybean seed dryers based on the ATmega328 microcontroller is not only a solution to the problems faced by farmers but also contributes to improving the quality of agricultural products in Indonesia. This kind of innovation is expected to be widely adopted, so that it can help increase the productivity and quality of other agricultural commodities in the country.

Future Work

Future work includes:

Improving the accuracy of the DHT22 sensor: The accuracy of the DHT22 sensor can be improved by using a more accurate temperature and humidity sensor.
Adding more features to the system: More features can be added to the system, such as automatic monitoring of water content and automatic control of the heating element.
Scaling up the system: The system can be scaled up to accommodate larger quantities of soybean seeds.
