1. Equipment heating of raw sugar: Heater
2. The temperature control device: thermocouple, Controller
3. Insulation Division: In the mold using HRS has added insulation (space) to prevent an increase in temperature of the mold
4. Division adjust the movement of V / cell:
Piston, V / PinVpin linear motion up and down by compressed air pressure pushes the piston moves in the cylinder translational
