Nanotechnology based Solar Dryer and Electric Smoker developed by AdtU & NERAMAC

By AT News |

Two innovative food processors namely a ‘Solar Drier’ and an ‘Electrical Smoker’ developed jointly by Assam down town University (AdtU) and North Eastern Regional Agricultural Marketing Corporation Limited (NERAMAC) were inaugurated at National Agri Horticultural Show 2021 on 21 January being held at Bokakhat, in Golaghat district of Assam by Atul Bora, Minister of Agriculture, Horticulture & Food Processing, Animal Husbandry & Veterinary, Govt of Assam. 

The processors were developed under an MoU signed between these two leading organisations. 

Talking to Assam Times, Dr Sunandan Baruah, Dean of Engineering & Technology and head of the innovation team of AdtU said, "The Nanotechnology based Solar Dryer uses an indirect heating technique to collect solar phonons and heat up a closed chamber which can be used for drying fruits, vegetables, fish, meat, etc. The prototype is equipped with 3 heating trays of dimension 2 feet by 2 feet. A typical outside temperature of 28oC can generate a chamber temperature of about 75 oC. The chamber temperature can be controlled using an electronic controlling system to maintain the taste and aroma. The drying trays are given an antifungal/antimicrobial nanocoating to ensure that the products that are dried are free from bacteria and fungi. The design can be scaled up/down to customize to user needs."

"On the other hand, the Electric Smoker is designed to smoke agricultural/horticultural/Meat/Fish produce to add flavour and ensure long shelf life. The traditional way of smoking creates carcinogenic compounds which can lead to health issues when consumed. The smoker designed at AdtU minimize the production of carcinogenic aromatic compounds and ensure safety of consumption of the smoked products. The smoker can also be used as a electric grill. The trays are coated with bio safe nanomaterials to ensure that fungal and microbial growth does not take place and the products have enhanced shelf life. The smoking can be carried out using wood dust from different plants, especially hard wood of fruit trees", Dr Baruah added.

The machines were also demonstrated before Rajesh Prasad, IAS, Principal Secretary to the Govt. of Assam; Akashdeep, IAS, Commissioner & Director, Agriculture, Assam. Few Ambassadors of African Nations also admired the prototypes and evinced interest in taking the technologies to Ghana. NERAMAC Managing Director Manoj Kumar Das and Dr Sunandan Baruah, Dean of Engineering & Technology, AdtU were present with their respective teams. 

It may be mentioned that NERAMAC, which is the only PSU to have 13 GI registrations in the world, which is for farmers’ benefit. NERAMAC participated in National Agri Horticulture Show 2021 with seven entrepreneurs from North East India. 

NER is a Bio Diversity Hot Spot of the World and due to its exotic eco system has evolved rich flora and fauna. It is rich in fruits and vegetables like Banana, Jackfruit, Areca-nut, Cashew-nut, Litchi, Orange, Star Fruit, Cauliflower, Cabbage, Sweet Potato, Tapioca, Tomato, Brinjal, Pumpkin, Wood Apple,  Bitter Gourd,  in large quantities and exotic fruits and vegetables like Elephant Apple, Tamarind, Plum, Olive, Assam Lemon, Ash Guard, Passion fruit, Drumstick, Hibiscus etc. and spices like Large Cardamom, Ginger, Turmeric, Chillies, Black Pepper, Star Anish, Jabrang, Alpena Galenga, Bay leaves, Long Pepper, Pipli, Cinnamon etc. It is also very rich in Medicinal & Aromatic Plants like Amla, Ashwagandha, Curry Leaves, Sugandh Mantri, Harad, Bhumura etc. It also of late started adopting high value exotic fruits like Dragon Fruit, Strawberry, Cocoa, Apple Plum etc. which is giving additional income to the farmers. NERAMAC has been procuring, processing and marketing these products through out the country through its marketing network.

Much of these above produces are wasted or are sold at throw away prices due to lack of primary processing, storage, conversion to products etc. These innovative processors are desired to be placed at household level to imbibe a culture of value addition at farm gate. This will help aggregation and marketing at scaled up level.Speaking on the occasion, Hon’ble Minister suggested development of a drier for reducing moisture in Assam Rice.

Fighting CAA in Court, Sharing Power in Govt – Where Does AGP Really Stand?

The Asom Gana Parishad (AGP) loves to wear the mantle of regionalism. It proudly recalls its birth from the Assam Agitation and the sacrifices of 855 martyrs. Yet every fresh controversy over the Citizenship (Amendment) Act (CAA) exposes the party for what it has become: a political outfit addicted to power, reduced to theatrics whenever Assamese identity is threatened. The script is depressingly familiar. In 2019, when CAA protests shook Assam, AGP staged a high-decibel drama—ministers resigned, alliance with the BJP was declared broken, the party promised to stand with the people. Two months later, under the cover of midnight negotiations, AGP crawled back into power, its leaders...

"Lawless Country—or Lawless Citizens?”: Gemini Loriak’s Viral Video Exposes Public Hypocrisy

Arunachal Pradesh law teacher Gemini Loriak has shaken the internet with a viral classroom talk that cuts deep into India’s collective conscience. In her fiery remarks, she dismantles the stereotype of India as a “lawless country,” declaring that it is not the absence of laws but the refusal of citizens to follow them that creates chaos. Loriak points to everyday hypocrisy: bribing to bypass queues, fastening seatbelts only when police are in sight, dismissing domestic violence as a “private matter,” normalizing harassment, and celebrating VIP culture while preaching equality. Quoting the Constitution—Article 14 on Equality, Article 21 on the Right to Life with Dignity, and Article...

Child’s death at Guwahati flyover site leads to arrests of contractor firm officials

In a swift development following public outrage, Assam Police have arrested three officials of Bhartia Infra Projects Ltd (BIPL) after the tragic death of a three-year-old boy who fell into an uncovered drain at the Arya Nagar flyover construction site in Guwahati. The incident, which occurred earlier this week, triggered shock across the city and led to demands for accountability from both the company and government authorities. According to reports, the toddler, identified as Sunit Kumar, slipped into an unguarded drain within the construction zone. CCTV footage and eyewitness accounts later revealed several exposed manholes and drains left unattended at the site. The flyover work had...

A Cry for Dignity on a Sacred Day

The morning broke like any other Teachers’ Day in Assam. Classrooms across the state were filled with garlands, songs, and the eager smiles of children bowing before their teachers. But while thousands of students offered prayers and gifts, more than 9,000 tutors left their schools behind and walked instead to the Latashil playground in Guwahati. It was here, on this very day of reverence, that the tutors chose protest over celebration. With banners aloft and voices hoarse with slogans, they demanded not flowers but justice. “We have given our entire lives to teaching,” one grey-haired tutor said, his eyes moist, his voice trembling. “Today we should have been in the classroom,...

Teachers’ Association Calls New Provincialisation Law a “Teacher-Killer Act”

Guwahati, September 5: On the occasion of Teachers’ Day, the All Assam Non-Provincialised Teachers’ and Employees’ Association strongly condemned the state government for neglecting their long-standing demand for provincialisation of services. Addressing a press conference at Dispur Press Club today, the organisation’s leaders narrated the decades of hardship faced by nearly 4,500 teachers and employees who continue to serve schools and colleges without provincial status. Many of them have been working since the 1990s but remain deprived of government recognition and financial security. Association secretary Purabi Kalita Saikia termed the new provincialisation law introduced by the...

Another Life Snatched by Guwahati’s Killer Drains

Guwahati today is not just a city of chaos and waterlogging—it has turned into a death trap. Open drains and reckless construction lie in wait, ready to claim lives, while the authorities responsible look the other way. This week alone, tragedy struck twice. Four-year-old Sumit Kumar slipped into an uncovered drain near Nilachal Nagar and never returned home. Hours later, Phuljit Sharma, an elderly citizen, fell into another open drain in Kahilipara, narrowly escaping death but left seriously injured. But Sumit and Phuljit are not exceptions. They are part of a long, shameful list. In 2023, Priya Kumari, a college student, lost her life when her scooter skidded near Ganeshguri and she...

Two Labourers Electrocuted at Guwahati Flyover Site: Zero Accountability, Safety Lapses Exposed

Another tragedy has struck Guwahati’s flyover construction drive. Two labourers lost their lives and others were grievously injured after coming into contact with an 11kV overhead power line at the under-construction GNB Road flyover. One of the victims fell from the structure after being electrocuted, while others narrowly survived. Shockingly, despite repeated accidents — 2 deaths and 5 injuries in just nine months — no investigation has been launched, and no agency has accepted responsibility. The Assam Power Distribution Company Limited (APDCL) has washed its hands off, claiming responsibility only “up to the electricity meter.” The Chief Electrical Inspector’s office says it...

Assam Erupts in Protest: AJYCP Slams Centre’s “Foreigners till 2024” Decision

The All Assam Jatiyatabadi Yuba Chatra Parishad (AJYCP) has launched a fiery protest in Guwahati, accusing the BJP-led Central government of “betraying Assam” by extending the stay of non-Muslim foreigners till December 31, 2024. According to AJYCP, this move tramples upon the Assam Accord and loads Assam with a 53-year burden of illegal migrants. Leaders warned that the Centre is turning the state into a “dumping ground” for Bangladeshis and destroying Assamese identity. “This government has insulted the memory of five martyrs of the anti-CAA movement. Instead of respecting Assam’s sacrifice, they have added ten more years to the foreigners’ burden,” thundered AJYCP president...
