JENSEN-SENKING BATCH TRANSFER DRYING TUMBLER DT 60, 90, 120, 140, 190, 240 High production capacity, low energy consumption
SENKING batch dryers, 60-240 kg capacity Applications For shaking, conditioning or full drying of water extracted linen The dryer works in conjunction with water extraction presses or centrifugal extractors and a continuous batch washer or washer extractors Installation possibilities Side by side in a twin configuration For various forms of heating Steam Gas Thermal fluid oil Inner drum, path ring, running wheels.
Mechanical design High drum volume for increased output Larger perforated surface of drum guarantees high evaporation performance Possibility to control the rotation speed of the drum by means of a frequency converter Largely dimensioned loading door opening, complete front wall can be swung away for maintenance Drum removable from the front and rear sides Easily accessible axial seals with long life All parts coming in contact with linen are made of stainless steel High temperature resistant large-drum wheels with very long life Strong steel housing, (heat and noise insulated) with large maintenance doors for lint filter and control cabinet Almost maintenance free, encased slip-on gear mechanism (no greasing, no tensioning of chains or belts) Large opening angle of unloading door for fast unloading Easy access to all maintenance points All drive elements are fixed by conustensioning elements, easy to maintain (no feather key connections) Control Integrated INTERBUS system for all dryers 100 freely programmable drying programs Visualisation data entry for the compound Drying time control by temperature comparison Advantages High evaporation performance Low energy consumption for heating and drive Low noise level by optimized efficiency of ventilator and strong insulation Reduced maintenance requirements due to longer lifetime of moving elements and good access to all maintenance points Flexible drying programmes for all kinds of linen by easily programmable PLC-control with operator guidance and clear wording indication Basic version steam heated dryer Pedestal height, h = 1025 mm Insulation of housing: Loading and unloading door: Strong heat insulation by double wall door Side doors (lint filter): outstanding insulation by 3-fold wall Basic version gas heated dryer Same as steam heated dryer, plus: Gas burner with full modulating gas valve Air recirculation device Flexible gas connection Monitoring of fan by pressure switch Monitoring of lint filter by differential pressure measuring Sprinkler connection Options Cool-down by: Fresh air flap Partially opened loading door Overdrying protection by temperature control Heat recovery with heating register for steam dryer Automatic lint filter with collecting bag in pedestal Automatic lint filter with suction transport to common collection station Temperature control by motorised valve for steam heated dryers by control of recirculation and fresh air flap by motor (mixed ratio between warm/cold air, based on the exhaust temp.) Additional pedestal heights in steps of 125 mm Teflon coating of inner drum (inside and outside) Loading chute for loading by monorail system Suction loading on loading or unloading side Unloading by tilting device with: Exhaust duct separator Flexible steam/gas connection Flexible water connection for sprinkler for gas dryers Special voltage/special frequency Maintenance platform on the discharging side for simple maintenance Drying time control via measurement of the moisture retention or infrared sensor Drive elements.
Air circulation different principles 1. 2. 1. Air circulation 100% air discharge. 2. Air re-circulation 20% discharge. 3. 4. 3. Air circulation cool-down with fresh air flap. 4. Air circulation individually adjustable mixing temperature for delicate linen. Fresh air Warm air Mixed air
