Resin Drying Time at 11% heat-up and bed-stabilization allowance: a worked example

This worked example runs the resin drying time numbers for a tougher week than the baseline: 11% heat-up and bed-stabilization allowance instead of the typical 15%. Estimate total resin drying time from dryer throughput, batch size, and a startup/stabilization allowance.

The inputs for this scenario

  • Resin batch size to dry: 100 kg (held at the documented default)
  • Desiccant dryer throughput rate: 25 kg/hr (held at the documented default)
  • Heat-up and bed-stabilization allowance: 11 % (the input this scenario stresses; the baseline uses 15)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base drying time = Batch size / Dryer throughput rate.
  • Total drying time (with heat-up) works out to 4.44 hrs at these inputs, and this is the headline figure for the scenario.
  • Net drying time works out to 4 hrs at these inputs.
  • Heat-up/stabilization time added works out to 11 % at these inputs.
  • Dryer throughput rate works out to 25 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where heat-up and bed-stabilization allowance sits at 15% and the headline result is 4.6 hrs, this scenario comes in 3.48% below the baseline at 4.44 hrs.
  • Use it when scheduling startups, material or color changes, and shift handoffs so resin is dry the moment the press is ready. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total drying time (with heat-up): 4.44 hrs (headline result)
  • Net drying time: 4 hrs
  • Heat-up/stabilization time added: 11 %
  • Dryer throughput rate: 25 pieces / min
