Pulse drying is an important step in the production of many pulse-based products. Proper drying is essential for ensuring these products’ quality, shelf life, and safety. Pulse drying can be an issue in certain situations because it can cause product quality problems. It is essential to carefully evaluate the Pulse drying to ensure uniform and gentle drying to prevent product quality issues. If you are worried about pulse drying, it is crucial to carefully evaluate the process and ensure that the appropriate precautions and quality control measures are in place. So what is the ultimate solution? Don’t worry; Steamax is here to help with the drying process.


Obstacles to Achieving Optimal Pulse Drying

It is essential to carefully control the drying conditions, such as temperature, air velocity, and humidity, to ensure that the pulses are dried uniformly without causing damage to the product. Pulses, which include beans, lentils, peas, and chickpeas, are high-protein, low-moisture foods that can be difficult to dry without causing quality issues such as over-drying or nutrient loss. Some of the main challenges associated with drying pulses include the following:

  1. Low initial moisture content: Pulses have a low initial moisture content, making removing the remaining moisture easier after over-drying the product.
  2. High protein content: Pulses are high in protein, which can lead to denaturation or degradation of the protein structure during drying, resulting in a poor texture and reduced product quality.
  3. Complex chemical composition: Pulses contain complex chemical compounds such as starch, fibre, and minerals, which can affect the drying process and the quality of the final product.
  4. Variable sizes and shapes: Pulses come in different sizes and shapes, which can affect the rate and uniformity of drying.
  5. Enzyme activity: Pulses contain enzymes that can lead to undesirable changes in flavour and colour during drying.

Steamax’s solution to Pulses Drying

The demand for pulses in India is enormous, with more than 25 million metric tons consumed annually. Many small and medium-scale processing units operate nationwide to meet this demand. During processing, the pulses require drying, traditionally achieved by burning diesel or wood logs in inefficient furnaces. This method is costly and environmentally damaging, resulting in high greenhouse gas emissions. To address this issue, we have developed a biomass combustion system (MREC) designed explicitly for these processing units. The key features of this unit include the following:

  1. The system lowers the drying cost by 30-60% and drying time by 20-40%.
  2. It consists of an auto-fuel feeding system, increasing efficiency and providing accurate temperature control.
  3. MREC is multi-fuel, meaning a single fuel type does not bind the customer. It is flexible to use various local biomass fuels.
  4. The unit, thus, results in clean and smokeless combustion.

By carefully evaluating the pulse drying process and implementing appropriate quality control measures and precautions, it is possible to minimize the risk of quality issues and ensure a safe and high-quality final product. In case of further queries, please feel free to CONTACT US.
