TROUGH WITHERING FAN

KEY FEATURES:

SPECIAL DESIGN - FRB FAN is designed in a manner such as to provide the necessary air current required withering the green tea leaves and sustaining the de-moisturization process with varying gust upto 76000 m3/Hr and Static Pressure of 12.7mm WC.

CASING - Heavy Gauge MS Sheet of high grade and corrosion resistant quality is fabri¬cated with flared inlet fro smoother and increased suction.

IMPELLER - Made of Die Cast Iron and with Aerofoil design and tested. Positioned with dynamical balance and directly mounted onto the Rotorshaft.

BLADES - The aerodynamically designed Blade Profile of the impeller to deliver optimum air quantity with minimum Power Consumption. The pitch of the Blade can be varied based on air flow and high effeiciency requirement.

PROTECTION GUARD -Fabricated with Weld mesh on a circular frame is bolted at the free end of the casing to prevent damage to the impellers.

FAN - Dia ranging from 36" to 54" with 2 to20 HP motors suitable for 415V ± 10% as well as 380 V ± 10 %, 50 Hz ± 5%, 3 Phase power supply.

MIXING CHAMBER - Made of Fabricated Steel with Damper fixed dual air entries one for Hot air inlet in the sides and another for fresh air in front and in the axial with the fan. The Hot air can be provided through drier exhaust or any heating source.

SPEED CONTROL SYSTEM -Variable Speed Drive ,AC Inverter controls the speed of the Fan Motors.

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.

AUTOMATIC SPEED REDUCING SYSTEM -A PLC Reducing System with Step down system increased to seven times and five different programmes available.

*  Due to Continuous Development Process the Design is subject to change without notice.


Advantages:

Simple and Rigid Construction.

For uniform current of air the Impellers are in dynamically balanced position.

Upgraded Steel have been used for Casing.

The blade Profile is designed for maximum air flow with minimal effort.

Protection Guard made with Weld Mesh is bolted to avoid damage to casing.

Available in 3, 5 & 7.5 HP models

Direct drive and belt transmission.
