ABSTRACT
The main objective of Muskmelon seed drying is the reduction of its moisture content to a safe level and to overcome the main problem associated with the drying of muskmelon seeds. The problem encountered during convention drying is the lump formation causing uneven and under-drying of muskmelon seeds, therefore vibro-fluidized bed dryer (VFBD) was designed with better heat and mass transfer and shorter drying time. Muskmelon seeds were dried in the VFBD at 60°C, 70°C and 80°C and drying characteristics were studied. VFBD is having capacity 7-8 kg/batch, air flow rate of 700 m3/h, bed velocity of 1.9 m/s. The frequency of the vibrations was varied between 6 to 11 Hz and the amplitude of vibrations was 10 mm. Average moisture content of seeds was reduced from 100% dry basis db to 7% db. Based on experiments it was found that time required to dry the seeds is considerably reduced when drying at higher temperatures i.e., at 80°C for 25 minutes.
Key words: Drying, Vibro-fluidized Bed Dryer, Moisture Content, Fluidization, Drying Rate.
