Opportunity:
A manufacturer requires a heating controller for candy processing. They want one control that will do several functions. The control needs to be easy to setup and use.
Problem:
The manufacturer needs to heat up their candy to a temperature of 200°F using the "ramp to set point at start" to prevent damage to the candy at start up. Once it reaches 93°C (200°F), two things need to happen:
- Inform the operator "batch finished" via a pilot light and remain "on" until this batch is removed.
- Automatically change the set point from 93°C (200°F) to a cooler 76°C (170°F) until this batch is drained, which could be hours later. This prevents the candy from being overcooked.
Solution:
The 988B-25BD-JARG and DB1C-3027-K200 DIN-A-MITEs®;, along with a sanitary RTD probe for direct immersion into the candy was a perfect solution! Our three outputs were able to:
- Output 1 - 240V control voltage to four DIN-A-MITEs wired in parallel set at 93°C (200°F).
- Output 2 - 120V control to a pilot light and latch it on at 93°C (200°F), event 1 input resets it.
- Output 3 - Used as an input for "event 2," which tells the control to go to an idle set point of 76°C (170°F).
Once the batch is removed and a new batch is filled, the "start batch" input needs to be pressed and the pilot light will turn off. The main set point of 93°C (200°F) is reinstalled.
