VIBRATORY FLUID BED DRIER

KEY FEATURES:

UNIQUE DRIVE MECHANISM - This is specially made for Vibro Fluid Bed Drier for accurate adjustment of drying time.

VIBRATORY BED - supported by leaf spring arrangement providing circular mixing and necessary velocity for Ideal Fluidisation.

PLENUM CHAMBER - specially designed based on aerodynamic requirement with Indepen¬dent Suspension and completely insulated and fabricated with High grade Steel.

HOT & COLD AIR BLOWERS -fitted with Heat Slingers , Aerodynamically designed and tested Impellers Dynamically and Statistically Balanced.

DUAL STAGE TEMPERATURE DRYING -for effectively arresting of Fermentation and minimising the loss of Essential Organic Compounds.

DUST EXTRCTION SYSTEM - consisting of Special Centrifugal Fans, Multi Clones and External Cyclones to extract humid air,wet tea particles from the drier bed and recycling the wet particles for polish drying and to collect fully fired Tea dust respectively.

HI-TECH AIR BALANCE MECHANISM - To ensure almost zero Fly-off and to provide nominal suction Pressure.


OPTIONAL FEATURES:

MANUAL CONTROL SYSTEM - 4 Stage Manual Control Knob is provided outside of the Inverter Casing since the Fan has to work in Full speed initially to remove moisture and then reduced speed is required.This requires Human supervision to vary accordingly.

FEED CONVEYOR - Compact Fees Conveyor with Food Grade PVC Belt feeds the fermented Tea uniformly into the drier by using Stainless Steel Spreaders to distribute to the Belt width.

VARIABLE FREQUENCY DRIVE - To control the rate of vibration of Plenum Chamber and residence of Tea in chamber controls firing

OPTIONAL FEATURES:

AGITATOR - To reduce the Ball formation by gently spreading the tea particles using slow rotating Stainless Steel Shafts for effective Orthodox Tea.

AIR DIRECTIONAL LOUVERS -To ensure Uniform drying in each temperature zone in the Plenum Chamber by adjusting Air flow independently changing the direction of air flow and to momentarily control the residence time and to prevent over and under firing.

HEATERS - To control the rate of vibration of Plenum Chamber and residence of Tea in chamber controls firing

AUTOMATION - To maintain the temperature of Hot air within the Plenum Chamber and automatically adjust Tea discharge depending upon the moisture and temperature of Fermented Tea for Homogenous Prime Quality Tea and Fuel savings.
