The spiral vibration heat exchange dryer moves, dries continuously and mixes uniformly particles on the spiral heating plate. So this system is adequate to dry the powder-type food materials. The mass and heat balance equation is used to design dry capacity and water content measurement, sieve analysis and vibration moving test are practiced to lay out the spiral plate. Spiral vibration dryer(300 kg/hr) is manufactured and tested by Dashida powder of 4.8% water content at 80~85oC. The frequency of vibration motor is operated 45Hz, 55Hz, 60Hz and the product mass per time is measured by digital scale. The water content of product is 1.0~1.6% and the dry efficiency is 67.4~78.2%. The spiral vibration heat exchange dryer make 125~363 kg/hr of Dashida dehydrated with temperature consistency and without dust in case.
