Traditional Drying Method:
Green Tea Drying: In Conventional drying process, leaves are swivelled for nearly 30 minutes at 55°C warm air.
In this process, the leaves lose about 50% of their moisture content. But physical and chemical changes occurred during drying process which affects the final tea quality. Black tea drying: In Conventional Drying Process, hot air
at 120°C is passed over the product for removing the moisture content. The colour and aroma in tea comes
from different constituents like polyâphenols. At high temperature some of these constituents is getting lost
and affect the final quality of the tea which can be minimized if temperature is low.
Continuous Infrared Microwave Tea Drying Method:
Twin Engineers has developed Continuous Tea Dehydration Technology which includes sequential Infrared Hot air & Microwave system especially for the Tea Processing. There is no requirement of Boiler or any other type of fuel in this technology. This is a fully electrical system with control of Belt speed, Product Temperature & Power Density.
ï· In Infrared Microwave Tea Dehydration Technology, uniformly heating of every
edge of tea avoiding burning corners, stem and edges. We can have better
quality tea product without any coal smoke effect as compared to hot air
ï· There is no wastage of energy in structure and environment heating as in
conventional heating. No need for preheating of the system so energy & time
ï· Infrared Microwave technology is a low temperature drying process.
ï· The structure of cells is uniform and better maintained by microwave drying.
The tea quality can be assured by using Infrared microwave dehydration with
less damaged cell structure and more retained nutrients which correspond to
the highest sensory score.
ï· With Microwave â Infrared Drying technology we can have commercial
sterilization effect within drying process. We can also have special sterilization
module with drying line which will have efficient microbial load killing effect in
less time. Because of this, product shelf life will be increase with Microwave
Infrared drying process compared to conventional.
ï· Environment friendly, Instant start up & Instant shut down are attractive
features of the system.
ï· Space and time saving with clean working environment are another attractive
features of this technology.
ï· Product Temperature Indicator with Controller
ï· Belt Speed Control
ï· Microwave power control
ï· Multi magnetron system for uniform Heating
ï· Modular Design â In Future expansion you just
have to add module in place of total new
ï· Energy Efficient & Environment friendly
ï· Emergency Switch
Twin Engineers not only sell Drying System but also support in process setting for your product. We are also having process lab in
our company to take process trials for new products.
