There is an NGO called Rural Communes based on the foundation of development, Rural Communes, founded in 1974 with the sole purpose of finding the right means to create a livelihood for the marginalized rural individuals and empower the society through Sustainable Development which is mainly focused on woman empowerment. One woman entrepreneurship group makes Nirgudi Oil for medical purpose disease like Simple Arthritis(Sandhiwat). This group is helped by Rural Communes. This woman entrepreneurship group makes Nirgudi Oil by manual process. So they require automation for large scale production and reduce human efforts. So we helped them for automation process.

Ashwini Bhandare, a DIC intern who has worked on this project with me.

For more information her project blog link:-

In this link, she has explained the whole process how they are making manually and she visited one more place Pen where they are also making this oil. I am her guide in this project and here is what I contributed to this project:-

Basically, this project was related to automating the whole process of Nirgudi Oil Extraction. In this project, we needed Stainless Steel Fabrication. In Ashram we don’t have this facility. So we decided to outsource this fabrication. As per discussion with Ranjeet Sir, I went to meet Anil Gosavi Sir, who was Ex-student of Vigyan Ashram, Pabal and is a Mechanical Engineer, They have their own company and fabrication workshop named as Climber Engineer located in Katraj. They have 25 years of experience in Design and Fabrication. They have developed 32 products in various sectors such as composting, agriculture and many more. They give us S.S. fabrication facility for developing the product.

I discussed this whole fabrication process with Anil Sir and decided to make this project in his workshop. Ashwini and I finalized some designs and materials and processes how we will make this machine. After discussing with Vaishali Gavande (Rural Communes) we passed the quotation and started working on the project.

After discussion with we approved design from Anil Sir, we have finalized this kind of design:-

We discussed all the materials required for this automation process. As per discussion with Rural Communes, they said all material should be stainless steel. So we make all material list and purchased this from the market.

We have finalized the following project material list:- while discussing with Anil Sir for making this machine:-

Open Steel Vessel 90 literBall ValveSocket
BurnerGas Pipe 
StirrerShaft(Stainless Steel Rod)Sleeve with 6205 BearingsBushSteel thick platesThreaded rodNutsBolts
Tube frame for supporting motor4mm hollow pipe,Nut and Bolts, WasherS.S. plates frame supporting for Motor and Stirrer

We bought this material from Rameshwar Chowk, Bhori Ali, Shukrwar Peth, Pune.

Some material was provided by Anil sir from his workshop. We bought S.S. material from Milan Metal, Katraj. We bought Ac synchronous motor from Srijan Control Drives, Katraj.

Working and Construction Process:-

1] First we fabricated burner to fix steel vessel like this:-


This fabricated burner will hold the 90-liter volume of S.S. vessel to heat.

2] After that we fabricated steel vessel and give outlet port of ball valve and socket drain out the oil like this:-


This steel vessel is fabricated and fixed with one ball valve with a socket to drain out the final product.

3]We fabricated 4mm thick hollow tube frame to hold the motor and stirrer like this:-


This hollow tube frame will hold the motor and stirrer.

4] We have fixed motor and stirrer shaft in a sleeve with bearings like this:-


The motor will rotate the shaft of stirrer through love jaw coupling and sleeve will hold the motor and stirrer shaft.

5] Again we fabricated stirrer blade in a bush like this:-


This stirrer blade is fixed in a bush, this will rotate stirrer shaft and will create vertex or stir the mixture of sesame oil and extraction of Nirgudi leaves.

6] RC unit and Motor:-


This box is the input of Motor, the motor requires 230V and 10A. This RC unit is providing exact power input to the motor.

7] Programming box of temperature:-

In this box, we have set temperatures for a buzzer. At 60-degree celsius buzzer will sound two times and the green LED will blink. At 80-degree celsius buzzer will sound four times and the yellow LED will blink. From 110 to 125-degree celsius buzzer will beep continuously sound and red LED will blink continuously. After 125 buzzers will sound continuous and a red light will on. Red LED and buzzer will indicate that we have to stop the heating process and turn off the gas.


8]Final assembly of this unit:-


After making this unit we have to take a trial on this model. So we did the whole process and take a trial on this model with Rural Communes.

While making the Nirgudi Oil whole process:-

1]While chopping the Nirgudi Leaves:-


2] While grinding the Nirgudi Leaves:-


3] While mixing water is mixed with grinded nirgudi leaves to make the extract:-


4] While filter the extract from grinded nirgudi leaves:-


5] Remaining dried nirgudi leaves after extraction:-


5] While pouring the Sesame oil in the vessel:-


6] While heating sesame oil up to 60-degree Celsius:-


7] While adding extract of nirgudi leaves in the vessel of heated Sesame oil:-


8]While stirring the mixture of Nirgudi extract and sesame oil:-


Trial video of stirring a mixture of Nirgudi extract and sesame oil:-

The video of programming box for buzzer alarm at 80’C.

We have marked on S. S. vessel to know exact liter in the vessel. It will know us that how much water should be evaporated.
