INVT GD200A VFD Solution for Flour Mill and Oil Extraction Applications

Abstract: This article introduces the INVT GD200A VFD solution for flour mill and oil extraction applications in the agro-processing industry. By combining solar power with the GD200A inverter, the solution enables stable motor operation, reduces energy consumption, and lowers operating costs, making it suitable for atta chakki and oil expeller applications, especially in regions with unstable grid supply.

Keywords: GD200A solar drive, flour mill & oil extraction.

I. Introduction

An atta chakki, also known as a flour mill, is a machine used to grind grains such as wheat, rice, and corn into flour. The term "atta chakki" is commonly used in India and South Asia, where it is a popular household appliance used for making fresh flour for cooking and baking.

Oil presses, also called expellers or presses, use high pressure and heat to “squeeze” the oil out of plant products. These products – including seeds, nuts, vegetables, fruits and leafy plants – release their oil through this mechanical process.

Application process:
1) Power generation by the help of solar panels from sun light.
2) Then the power used to run drive and from where Expeller & Atta Chakki.
3) Oil extraction means to get oil from mustard seed & Atta Chakki is used for make wheat flour.
3) Here motor we used is of 11 KW & drive of 18 KW.

III. Advantages and benefits

* Firstly, Solar VFDs are energy-efficient, thus significantly reducing energy consumption cost.
* Increase productivity as in case of grid supply one need to wait for supply so in solar vfd we use solar supply.
* With the combination of solar energy and GD200A VFD technology, operational costs can be significantly reduced. The initial investment in a solar-powered system with a GD200A VFD can lead to substantial savings in electricity bills, making it an economically viable option for small-scale millers.
* By minimizing mechanical stress and wear on the motor, GD200A VFDs can prolong the lifespan of the atta chakki. Smooth starts and stops, along with controlled acceleration and deceleration, reduce the risk of damage, leading to lower maintenance costs.

IV. Conclusion

GD200A inverter is successfully used in multiple sites in India.

The combination of GD200A VFDs and solar power in atta chakki & Oil Extraction represents a significant step towards modernizing the traditional milling process. By enhancing energy efficiency, improving performance, and reducing operational costs, GD200A VFD play a crucial role in making solar atta chakkis & Oil Extraction a sustainable and economically viable option for millers.

As the agricultural sector continues to embrace renewable energy, the integration of these technologies will likely become increasingly important, paving the way for a more sustainable future.

INVT will continue to be committed to innovation and research and development of solar vfd products, providing customers with greener and more efficient solutions.
