Martins Vibro Fluid Bed Drier is a quality drying machine which
works on the principle of vibrating Fluidized Bed. The wet tea is
dried efficiently by a control, uniform flow of hot air from any
source of heat. Fermented tea leaf is fed through a feed system
to the Drying chamber where mixed conditioned hot air is introduced
underneath a perforated Stainless Steel grid plate which carries
the wet tea by the principal of fluidization conveyed by combination
of hot air and vibration. In this process fermented tea is dried
uniformly to achieve best quality tea.
The drier has a feeding conveyor which delivers the wet fermented
leaf into the drying chamber. The chamber is actually the vibrating
bed with perforated grid plate under which hot air is forced in
an uniform manner from the Plenum Chamber. The hot air duct is aerodynamically
designed to force air through out the bed in a control manner.
The vibration is created from an eccentric drive transmitting
to the drying bed resting on series of specially designed spring
blades. The vibration is smooth giving uniform flow of air through
the grid plate and the wet tea moves forward in a fluidized manner
and is dried in the process.
The drier has a robust steel construction and fabricated base frame
and Stainless Steel plenum chamber which is well insulated to give
the maximum thermal efficiency. All contact point of wet tea is
on SS Sheets.
The sophisticated control panel with high sensitive
tripping system for the protection of the equipment is supplied
with the machine. IIRC fuses are used. Indicator lamps are provided
for overlapping tripping. Four temperature indicators and single
point controller are introduced through sensors to see the temperatures
inside the drying chamber.
SS 304 grade sheet is carefully
performed to make the air flow through this in a controlled manner
and gives forward direction of fluidization. This determines the
quality of the product from the Drier.
