Ctc Tea Processing Machineries

Continuous Chemical Withering Machine

Chemical Withering:

Responsible for changes in the chemical properties of the leaf shoot, which eventually develops the liquor quality of made tea.

Minimum duration should be 6 hrs under controlled conditions of - air exit velocity, volume, static pressure, relative humidity, and dry bulb temperature.

The objective is to achieve 'zero moisture loss'.

Advantages of separate mode of chemical withering:

1. Savings in space - Withering troughs not required.
2. Savings in labour - Numbers of workers required for withering 1-2.
3. Savings in energy - Reduction of power in withering section
4. Consistent quality of withering.
5. Automatic spreading of leaf inside both CCW and CPW

Feature:

1. Specially imported belt for conveying of leaf.
2. Main dive and driven rollers with auto tracking belt arrangement.
3. Variable frequency drive to monitor and control residence time of chemical wither.
4. Unique feeding mechanism for uniform and proper distribution of leaf in the container.
5. Specially designed distribution plate for uniform air distribution.
6. Aerodynamically designed fans with individual humidification system.
7. Centralized Operating console with AC variator and throughput time indicator for residence time control.
8. Discharge doffer arrangement.
