Pulse drying is critical in producing many pulse-based products, as it directly impacts their quality, shelf life, and safety. However, achieving optimal drying can be challenging due to various factors affecting the process. If you’re concerned about pulse drying issues, it’s essential to carefully evaluate the process and implement the necessary precautions and quality control measures. So, what’s the ultimate solution? Don’t worry—Steamax is here to help with an innovative approach to the drying process.

Obstacles to Achieving Optimal Pulse Drying

Proper drying conditions, including temperature, air velocity, and humidity, ensure pulses dry uniformly without damaging the product. Pulses, such as beans, lentils, peas, and chickpeas, are high in protein and low in moisture, making them difficult to dry without encountering quality issues like over-drying or nutrient loss. Some of the main challenges associated with pulse drying include:

• Low Initial Moisture Content: Pulses naturally have a low moisture content, making it difficult to remove the remaining moisture without over-drying the product.
• High Protein Content: The high protein levels in pulses can lead to denaturation or degradation of protein structures during drying, negatively affecting texture and overall product quality.
• Complex Chemical Composition: Pulses contain a mix of starch, fibre, and minerals, complicating the drying process and potentially impacting the final product’s quality.
• Variable Sizes and Shapes: Pulses come in various sizes and shapes, affecting drying rate and uniformity, making it challenging to achieve consistent results.
• Enzyme Activity: The enzymes present in pulses can cause undesirable changes in flavour and colour during the drying process, further complicating the task.

Steamax’s Solution to Pulse Drying

The demand for pulses in India is substantial, with more than 25 million metric tons consumed annually. To meet this demand, numerous small—and medium-scale processing units are spread across the country. Traditionally, pulse drying is achieved by burning diesel or wood logs in inefficient furnaces, a costly and environmentally harmful method contributing to high greenhouse gas emissions.

Steamax has developed a biomass combustion system, the MREC, specifically designed to address this issue in these processing units.

• Cost Reduction: The MREC system can lower drying costs by 30-60% and reduce drying time by 20-40%.
• Enhanced Efficiency: It includes an auto-fuel feeding system that boosts efficiency and provides accurate temperature control, ensuring consistent and high-quality drying.
• Multi-Fuel Flexibility: The MREC system is multi-fuel compatible, allowing customers to use various local biomass fuels instead of a single type.
• Clean and Smokeless Combustion: The unit ensures clean and smokeless combustion, making it an eco-friendly solution that significantly reducing environmental impact.

Conclusion

By carefully evaluating the pulse drying process and implementing appropriate quality control measures and precautions, the risk of quality issues can be minimized, and a safe and high-quality final product can be ensured. Steamax’s biomass combustion system offers a modern, efficient, and environmentally responsible solution to the challenges of pulse drying.
