General Description

The Computer Controlled Teaching Yogurt Incubator, "IYDC", is called yogurt maker or yogurt heater. This yogurt maker consists of aninsulated central body where yogurt fermentation is carried out.

There is a series of shelves inside to place the containers where yogurts are formed.

There is also a heating element to control the temperature required to make yogurt anda fan to cool down the unit and avoid overheating.

The instrumentation required for a complete monitoring of the process is also included:

  • Temperature sensor to measure the temperature inside the unit.
  • Temperature sensor to measure the temperature of the yogurt at any moment duringthe process.
  • pH sensor to measure the pH of the yogurt at any moment during the process.

For a safe operation, the unit includes a safety switch to prevent the heating elements from working with the door of the unit open.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + aControl Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, forcontrolling the process and all parameters involved in the process.

Exercises and guided practices

MORE PRACTICAL EXERCISES TO BE DONE WITH THE UNIT

  1. Many students view results simultaneously. To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
  2. Open Control, Multicontrol and Real Time Control. This unit allows intrinsically and/or extrinsically to change the span, gains, proportional, integral, derivative parameters, etc, in real time.
  3. The Computer Control System with SCADA and PID Control allow a real industrial simulation.
  4. This unit is totally safe as uses mechanical, electrical and electronic, and software safety devices.
  5. This unit can be used for doing applied research.
  6. This unit can be used for giving training courses to Industries even to other Technical Education Institutions.
  7. Control of the IYDC unit process through the control interface box without the computer.
  8. Visualization of all the sensors values used in the IYDC unit process.
  9. By using PLC-PI additional 19 more exercises can be done.
  10. Several other exercises can be done and designed by the user.
