ALPHA BATCH DRYER

ALPHA BATCH DRYER

The batch transfer drying tumblers are designed for the fully automatic shaking as well as pre- and full drying of water extracted linen batches.

 

They can be operated either within a complete washing system along with water extraction presses or centri-fugal extractors, in the preset cycle of the tunnel washer or in systems with washer extractors. It is also possible to operate the dryers as an isolated application without a direct connection to other machines. The dryer design allows a space-saving mirror positioning of two -dryers, directly side by side. The dryers can be heated in different ways, steam or gas is available.

 

Particular attention was paid to reach the highest possible productivity at simultaneous lowest media consumption keeping a very low maintenance effort. The housing was sealed and insulated carefully in order to use the energy for the drying process in an optimal way. Loading, unloading and revision doors were designed with multiple layers in order to keep the heat losses as low as possible.

 

Control:

Each dryer has its own switch panel with PLC control and own power supply. The operation and programming of the dryer is carried out by a separate compound control that connects all dryers with each other. A panel PC with a colour touch screen operates and visualizes the dryers and their transport conveyors, if existing. The JENSEN service helpdesk can establish a remote maintenance of the dryer control via an integrated Ethernet interface. Dryers of an isolated application are equipped with a smaller graphic operating terminal. Each dryer disposes of 100 free programmable programs.

The JENSEN dryer compound control connects all ALPHA D5 dryers with each other.

Mechanical design:

  •  
  • High drum volume with large perforated surface for optimized air flow and high evaporation performance
  •  
  • Frequency controlled regulation of the drum rotation speed, dependent on the program
  •  
  • Complete loading wall is pivotable e.g. for easy access to the drum
  •  
  • Unique sealing concept against jamming of even very gentle linen types; all sealings are easily accessible
  •  
  • Inner drum with machined path rings for a smooth operation of the drum and a long lifetime of the gear elements
  •  
  • Drum wheels are resistant to high temperatures and have a huge bearing force
  •  
  • Stable and well insulated steel plate housing with revision doors which can be wide opened for an easy maintenance
  •  
  • Good accessibility of all maintenance positions
  •  
  • Tilting device for a faster unloading of the linen batch, including exhaust duct -separator
  •  
  • Direct drum gear that is easy to maintain (no greasing or tightening of chains or belts necessary)
  •  
  • Modulating burners in gas heated dryers for a precise temperature regulation
  •  
  • Loading door which closes to the top to avoid jammed linen
  •  
  • Sprinkler device for gas heated dryers
  •  
  • Flexible media connections (steam, gas)
  •  
  • Inner drum with removable segment plates
  •  
  • Automatically tuned guide rollers for the inner drum

 

Options:

  •  
  • Cool-down via partially opened loading door or fresh air flap
  •  
  • Air recirculation device for heat recovery (standard for gas heated dryers)
  •  
  • Temperature control with motor control valve for steam heated dryers (e. g. for very sensitive linen with regard to the temperature
  •  
  • Automatic lint removal with collection bag (remote for each single dryer or with central suction for several dryers)
  •  
  • Maintenance platform including handrail at the unloading side of the dryer
  •  
  • Higher pedestal (standard height: 1025 mm)
