PERFORMANCE EVALUATION OF DESICCANT SEED DRYER FOR DRYING TOMATO SEEDS

Abstract

The technical evaluation of desiccant seed dryer and analysis of dried tomato seeds for germination and vigour index has been done in the present study. Dryer can dry seeds in deep bed at safe temperatures for good shelf life, germination and vigour index. The dryer has two chambers one is air conditioning unit and other is seed drying chamber. The dryer has two mode of working i.e. seed drying and desiccant regeneration mode. We can change the flow of drying air from top to bottom and vice versa in seed chamber for uniform drying in deep bed. Desiccant used in dryer is silica gel. Tomato seeds were dried with hot and dehumidified air at five different drying air temperatures i.e. 38, 40, 42, 44 and 46⁰C and at five different air flow rates i.e., 1, 1.2, 1.4, 1.6 and 1.8 m3/min.. Germination of tomato seeds varied from 86-64% as temperature varied between 38-46⁰C, and vigour index varied from 1007.9 - 558.7.
