To
maximize the quality properties of black tea,12-16 hrs
of chemical withering is essential.
THINK AGAIN
Now it is possible in 4-6 hrs, ensuring superior quality.
Institute of Himalaya Bioresource Technology (IHBT) has
been doing research ,and discovered that it is possible
to accelerate both chemical and physical wither of green
leaf by creating controlled stress to trigger chemical
wither, This concept was patented six years back.
On the basis of this concept Mesco Equipment (P) Ltd,
designed and developed the machine which now is jointly
patented by IHBT and MESCO. After extensive trial the
machine is now ready to go for commercial use by the tea
industry.
SIGNIFICANT FEATURES
Controlled physical stress to trigger chemical wither.
Cooling at ambient temperature by cold air circulation.
Physical as well as chemical wither is achieved in
4:30 to 5:30 hrs for CTC and 5:30 to 6 for Orthodox.
The process work in all weather conditions.
Extra surface water on leaf will have to be removed
before setting the process. However if the process starts
with wet surface leaf it may become necessary to prolong
application of cold air.
The quality of tea through this machine is at par or
superior to normal process.
BENEFITS
Time saving—4:30 hrs to 5:30 hrs for CTC and 5:30 hrs
to 6 hrs for Orthodox.
Saving of energy by substantial reduction of number
of tough fan used.
Saving of fuel as hot air is not required.
Saving of man days.
Reduces the trough area requirement by 27% to 40% by
pre-treatment of green leaf.
SPECIFICATION
Compact with space requirement of 3.22 meter X 1.58
meter.
Flexibility of stroke and pressure in relation to horizontal
speed of movement.
Throughput 2500-5000 kg green leaf per hr.
One machine can cope with green leaf of a 10 lac kg
factory by adjustment of manufacturing time.
Easily adaptable to a continuous process from withering
to drying.
Substantial reduction of withering space requirement
and labour.
