Ice Making Machine

So most people are familiar with how regular ice trays work.
You put water into these pre-formed cubed trays. Place the trays into the freezer, wait, and then viola! you have ice!

Ice making machines aren’t as “simple.” Most machines use 1)an electric motor 2) water valve and 3) an electrical heating unit. To be able to get the machine up and running, you would need to connect it to an electrical circuit. The ice-making machine would also have to be set up to connect to the plumbing line to get fresh water.

Once this is all setup, the cycle can begin!

Step 1) A timed switch in the circuit delivers a current to a solenoid water valve. This valve is usually placed behind the fridge, and is connected to the central circuit by electrical wires. As the circuit sends a current, the charge move the solenoid, which then opens the valve.

Step 2) When the valve is open, it lets in enough water to fill the ice mold (plastic well).

Step 3) The machine waits for the mold to freeze. Throughout this process, the cooling unit in the fridge does the freezing work. The machine is able to tell the temperature of the water in the mold through a built-in thermostat.

Step 4) When the appropriate temperature is reached, another circuit sends a current to the heating coil, which is under the mold. As this heats up, the bottom is slightly melted, which loosens the cubes from the surface.

Step 5) Fresh ice is made, and the process is repeated!
