Tawseef Thokar innovates a device that removes impurities from food


When Tawseef Thokarit’s the mother had to endure the taunts family members on the presence of impurities in the cooked food, an idea germinated in his mind – an idea to create something that can remove 100% of impurities from food.

After careful consideration, he succeeded in making a device that could detect the presence of foreign particles in food products. When using ultrasonic transmitters and receivers, the device can detect metallic and non-metallic foreign particles.

Tawseef believed that conventional machines for processing and cleaning food grains are not enoughs pebbles and other impurities can be found even after the cleaning process. The most common method of cleaning food grains is gravity. The method is not effective for smaller particles. Mmost of the time impure particles are added as adulterants and which in the future can harm the health of a consumerhe said.

The device he made removes all impure particles regardless of their size. “IIn cooked or uncooked food, metal particles, hair, pebbles, insects and other impurities can be detected and removed, regardless of their size, and one can enjoy pure food,” Tawseef complaints.

The device – A container similar to a rice cooker includes a non-metallic bowl and a container for food. It uses different modes of detection of impure particles.

Talking about the use of the device, he said that it can be used for cooking food in hotels, restaurants and also in households.

A metal detector based on either electromagnetic field, radio frequency, eddy current or capacitance, as well as an ultrasonic transmitter and receiver are part of the device.

The device also includes an interpreter which will interpret the observations of the various sensors and alert the user accordingly.

However, X-ray based detection is considered to be the most accurate and affordable, but for this Tawseef said there is a need to develop a closed box for detection and such a setup would only be viable. for hotels and restaurants, while the ultrasonic device and vibrating pad can be used in hotels and restaurants and is also suitable for households.

A control unit and a plurality of piezo drivers are mounted at one end of the sensing probe, the control unit being adapted to control the operation of the device. The plurality of the battery is mounted at the second end of the sensing probe.

The battery is then connected via connection means to the switch mounted on the outer surface of the detection probe.

At the top of the detection probe, an LED indicator is connected via connection means. Vibration sensor interpreters are mounted on the bottom surface of the sensing probe.

The detection probe upon detecting a foreign particle or impurity in the food which is placed in the bowl and being heated, will detect and indicate the LED indicator. The LED indicator will turn red when detecting an impure particle and will remain green only when not detecting an impurity. Then the impurity will be washed away immediately.

The device being automatic replaces the manual checking of food grains, which is also not efficient and puts a lot of strain on the eyes and neck.

Tawseef said the device has enormous utility. “It’s also useful for students and workers who stay away from home and need to cook on their own and also don’t have time to check food manually,” he said. .

Coming from a modest family, he thinks that one has to pay more to buy good quality food and that the weaker strata of society have to make do with inferior food.

“The poor, who cannot afford to pay more money for food, often eat food with impurities and adulterants that only threaten their health. This device is a solution to all problems related to food,” he added.

Originally from Baghbal village in kulgam district, his father works as a farmer and his mother is a housewife.

He believes that there is no weakness that can prevent the person from doing what he wants to do. Among his friends, he is known to have original ideas.

He said: “Many ideas come to my mind, but I should have the satisfaction that my innovations work for the weakest part of society and they should benefit from it.”

Recalling the time when, due to the accident, he was bedridden for nearly 4 years and had to deal with 15 leg surgeries, he said: “I used to think it was my weakness, but now I realized that weaknesses and difficulties make you strong and take you on the right path.

Tawseef was scouted by NIF (National Innovation Foundation) Cell, J&K, Institute of Technology, University of Kashmir in 2015. He was later awarded Dr. APJ Abdul Kalam IGNITE Award by the then President of India, Pranab Mukherjee during the function organized by the National Innovation Foundation, an autonomous body of the Department of Science and Technology, Government of India at Rashtrapati Bhavan, New Delhi.
