Dharamveer Kamboj, from a rickshaw puller to a guest at Rashtrapati Bhavan

Kamboj has also visited various trade fairs and agricultural melas for promotion of his machine.  “I have been getting orders from abroad too. Currently, I have an order of 20 such machines from a firm in Kenya,” he said.

Speaking about his childhood, Kamboj said he was restless and inquisitive as a child.

When he was in Class VII, he used to make small heaters from old tin cans and coils and sell them for Rs 15.  

Kamboj's machine has a device capable of pulverizing and extracting oil or gel from various herbs.

The machine consists of an autoclave unit for sterilization, a boiler unit for boiling, the extractor unit for extracting juice or gel, a drive means for a source of power attached to the apparatus.  

The main chamber is enclosed with an oil jacket to avoid direct heating of the herbs.

The unit can process 100 kgs of Aloe Vera in an hour.  About 1.25 kg of Aloe vera leaves are converted to one litre of gel in the unit.
