The Duraisamy Modern Rice mills is a located at Chinna Salem, Tamil Nadu. The company was founded by Mr. Sundra Moorthy in 2003. Their brand Mayil(Peacock) is one of the famous selling brands in Tamil Nadu. They offer finest quality South Indian rice varieties like Thanjavur Ponni rice and Raja boham Rice which is sourced from reliable and local farmers. Possessing state-of-the-art processing and storage facility set up by bhuler. They have paddy storage of 4 silos of 1000 mt. capacity each. Known for aged single boiled rice, the standard storage time for rice is 1 year in controlled temperature. The biggest challenges for them is storing the grain in metal silo during the summers (the temperature can rise up to 42°C).
Due to grain temperature and humidity the risk of moisture, color, cracks are always there. They wanted a solution for paddy stored in silo with no loss. In 2018, Mr. Yuvaraj and his technical team showed interest towards using grain chilling technology from Grain Technik Pvt. Ltd. The loading cycle of the silo at site would begin in the month of Nov and end within Feb each year. The ambient temperature in summer range would be between 36°C – 44°C
In 2019, the GT-250 was installed and cools the grain from 40°C to 18° during the peak summer. Then after being monitored the moisture level and temperature for 2 months. The next cooling cycle is applied, the target is not to do deep cooling due to ageing. The detail method of cooling and the result are here(Know more) . in the next span of 2 months, the paddy was taken for milling and the results are here (know more).
The GT-250 proved to be an efficient tool to bring down the temperature & relative humidity to safe storage levels & met the performance parameters expected.
