Presently Tea Industry totally depends on old age technology based on batching systems for getting the tea made records which is not very reliable and huge complaint of frequent breakdowns are observed in many tea factories. TO OVERCOME this problem, Stesalit has introduced universally accepted Dynamic method for all event monitoring data of Dryer output. System Overview Stesalit Continuous Weigher (SCW) is uniquely designed for online continuous monitoring of tea made output from dryers. It is basically an electronically and sensor controlled specially designed belt weigher and can be easily placed in between dryer and sorting zone. It continuously records and displays all the events like cumulative output, total operation time, power cut time etc. This helps to monitor the productivity of the whole process at any instant. Salient Features Advantage Online display of current events like total operation time, power cut time and cumulative output Detailed event recording of individual batch for past 64 batches of all parameters with date and time Elaborate self diagnostics to detect the exact area of problems to get instant solution Easy and well defined calibration procedures for smooth and steady operation In case of power failure it starts automatically after one minute of power restoration All the parts come in contact with tea made are food grade stainless steel It can be linked with computer for remote monitoring of Stesalit Continuous Weigher (SCW) operation (optional) Different models are available from 300 kgs tea madehour to 1500 kgs tea madehour Dimension: L-1900mm x H-1200mm x W-970mm

Present practiceit is well accepted fact that relative humidity plays very important role during entire tea manufacturing at all processing zones. At present, tea planters are mainly dependent on conventional dry bulb & wet bulb thermometers and based on difference between dry bulb and wet bulb thermometers they derive the % rh from standard psychometric table. But it is very difficult to get the correct % rh since it is not possible to see the exact difference between dry bulb and wet bulb temperature in decimals and it is prone to get the erroneous %rh values resulting in taking incorrect decisions. To overcome aforesaid problem stesalit introduces the humidity management system which monitors the dry & wet bulb temperature digitally and display the % rh instantly following the standard psychometric chart. System overviewmicrocontroller based humidity management system senses the dry & wet temperatures of air through a highly accurate intelligent state-of-art sensor and directly computes the %rh as per the embedded psychometric logic inside. The single indicator & controller module digitally displays the current %rh and the dry bulb temperature of the surrounding air. The humidity management system has in-built facilities to set the lower and upper limits for the desired %rh, along with incorporated audio-visual annunciation control mechanism in case of any variation from the pre-set % rh limits. The control output signals can also be used to automatically activate de-activate any attached electro-mechanical devices in the installed air-humidification unit to maintain the desired %rh within the preset limits.
