| dc.description.abstract | India is largest producer of milk in the world contributing 23 percent of the global milk production with an average production of 198.4 million tonnes in 2019-20 (NDDB). About 65% of milk is handled by small scale milk processor and 35 % goes to organized sector. The quality of the milk processed at unorganized sector is not much good because of the unavailability of milk processing equipment for small scale processing and availability of such equipment’s which is not affordable for small scale processing i.e. use of boiler sometimes is not feasible as it requires high initial investment. With this view Electric based milk heating system was designed and fabricated. Preliminary trials were conducted to confirm the feasibility of the system. Performance of the system was evaluated by heating milk from 4 to 90°C by using 3 paired heaters and 5 paired heaters for utilising different capacity of milk (10 L, 20 L, 30 L, 40 L, and 50 L) and cooling from 90°C to 37°C by natural cooling and by circulation of tap water. Performance parameters were taken as heating rate, cooling rate, temperature distribution, temperature profile and energy consumption. Time required to heat milk from 4°C to 90°C for capacity 20 – 50 L was observed to be 76 min to 151 min by using 3 paired heaters and 56 min to 106 min by using 5 paired heaters. Heating Rate and cooling rate for 20 L to 50 L using different paired heater was found to be 1.32 – 0.57 °C/min and 0.88 – 0.61 °C/min respectively. Localized heating on the vessel surface was reduced because agitator helped in proper mixing and better distribution of heat in complete vessel. Temperature gradient and energy consumption was found to be in range 0 – 1.30°C and 4.65 to 9.91 kWh for 20 L to 50 L capacity respectively. | |
