Problem Statement:

More energy consumption during making the mawa


This is a mawa maker where the steam circuit (boiler, kadai, condenser, pipes) has been made as a closed leak proof design resulting in better fuel efficiency and minimal wastage. The used steam is also fed to the boiler alongwith condensate water through gravity. The close circuit design stops leakages, thereby reducing the additional water requirement (reducing from 1ton per hour to few liters per hour). Also the wood consumption has reduced drasticallyusing redesigned boiler with horizontal fire tubes, preheating of air with flue gases, and recycling of the steam back to boiler without condensation. The water filled in the boiler can be continuously used for a long time unlike traditional mawa machines, where it has to be filled almost every half an hour. Further to reduce human efforts, he has made the stirring operation automatic. In conventional practice of mawa making in kadai, continuous stirring is needed to prevent milk fat from sticking to the walls of container. For this, at least one person is needed at each kadai. Subhash has designed an automatic machine, which can process 10-12kg milk in a single batch with mechanized stirring and unloading of the prepared mawa. The heating requirements are accomplished by steam supplied from a wood fired horizontal fire tube boiler in closed circuit. The boiler is supplied with preheated air (heated using flue gases) by a blower, which is connected via a pressure actuated switch. The automatic operation of the boiler and machine reduces the wood consumption per unit of mawa produced considerably, while saving labour costs. This concept can also be used for efficient heating in dairy & food processing, textiles, rubber, plastic industries. Subhash is making machines with capacity ranging from 40 lit/h to 3000 lit/h (Costing Rs 60,000 to 10 lakh) depending on demand of customers. He has sold over 60 machines in different parts of North India. In all his creative pursuits, his mother has been a continuous source of help though his father believed he was wasting money. Being in a joint family also helped as he never had the pressure to make ends meet. A couple of other people also helped him to file a patent and generate resource for his work.
