Drying kilns for accelerated drying

type SKC
Home > Drying kilns for accelerated drying

The accelerated drying is most often used for drying soft wood species, high humidity.

 

Drying kilns of this type are characterized by higher thermal energy and faster air circulation.

 

All our drying kilns include: highly insulated aluminum construction, reversible heating and ventilation technology, maximum quality and drying performance, environmentally friendly solutions and energy efficiency.

CHARACTERISTICS:

  • The accelerated drying is most often used for drying soft wood species, high humidity
  • This dryer model has a higher installed heating power, increased air exchange and a larger number of circulation fans
  • Chamber capacity from 30 to 120m3 per drying cycle
  • Working medium: hot water system 90 / 70oC (max 120C) or steam 2.5 bar
  • Standard dryer width: 4,6/ 6,6 / 8,6 / 10,6 / 13,0 m
  • Standard depth of dryer: 7.0 m
  • Stacking height: 4.1 m
  • Automatic control of the drying process via the MC-2000 or MC-3000 automatic controllers installed for each dryer individually
  • Remote monitoring and control on a PC using Nigos DryerManager software, via RS485 standard

Heat recovery unit (recuperator) installed in chamber type SKC allows up to 50% higher heat recovery rates to be achieved. In addition of thermal efficiency, the use of a heat recovery unit also shortens the drying time and improves the quality of the dried material. Investment in heat recovery units is minimal and return of investment period is very short.

Energy consumption is also mitigated by the use of wood waste or sawdust as a fuel for heating the boiler, so this type of drying kiln is recommended to customers who have at their disposal a boiler or wood waste in significant quantities.

Drying kilns for accelerated drying allows more cycles per month.

“NIGOS – electronic” gives its customers 3 years warranty for whole kiln, and 5 years for the automatic control unit.

TECHNICAL FEATURES:

  • Complete construction of solid aluminum profiles allows high roof loads (up to 250kg / m2 of snow) and resistance of the drying kiln to wind gusts of 150km / h
  • Drying kiln walls made of aluminum cassettes, connected with stainless steel screws and silicone of high resistance to temperature and acid from wood
  • Insulation of hard pressed wool 10 cm thick
  • Exterior facade of sinusoidal aluminum sheets
  • Aluminum subceiling allows even circulation through all layers
  • Double sided heat exchangers made of stainless steel and bimetallic pipes stainless steel / aluminum 25/54
  • Reversible fans with high efficiency (H-class motors)
  • Energy saving by changing the fan speed, via frequency inverters for each fan separately
  • Flow speed through the stack is 3.5-4m / s
  • Heat recovery unit for air exchange enables finer air exchange and thermal energy savings of 30-50%
  • Additional servo flaps
  • High pressure humidifying system (pump, valve, filter, etc.); double: on the back wall and in the front of the false ceiling (nozzles, stainless steel pipes), harmonized with the direction of fans, which prevents the appearance of stains
  • Possibility of installing equipment, doors and control systems in the customer’s masonry building
