Desalination alludes to the methodology of expelling salt and different minerals from water. Water is desalinated with a specific end goal to change over salt water to new water so it is suitable for human utilization or watering system. In this paper, a novel design of pentagon still was designed and operated along with dryer using biomass energy to increase the productivity of desalination and drying efficiency of the dryer at THE same time. The basin plate of the conventional still was modified with wide area and double slope covers at the top to act as pentagon still the single basin dryer was operated in series. A biomass heater was connected in between these two to supply heat. The Pentagon still was operated with different depths of water, energy storing, exposure materials to strengthen its production. A heat exchanger was attached at the basin plate with extended surfaces to circulate heat. A conventional still was operated in the solar mode in the same location to compare the performances with modified still. Solar dryer was used to dry pineapple with the waste heat from biomass heart source. The productivity of pentagon still was 29%, 47% higher than conventional still when operated in solar, biomass heated modes. Addition of energy storage, exposure materials strengthen the productivity by 47%, 48%, and 41% respectively, adding extended surfaces in heat exchanger improves 20% in production. The drying efficiency was good in biomass mode when compared to solar mode. The payback period for the Pentagon still was very less. The energy balance for the boiler was also performed.
