Which type of ice maker has a continuous harvest cycle?
The type of ice maker that has a continuous harvest cycle.
Explanation of Solution
Flake ice is generally made in a vertical cylinder and is placed inside the evaporator. It is a thin piece of ice and can be seen in restaurants.
It is formed by maintaining a water level inside the cylinder. An auger is rotated at constant rate inside the cylinder. The machine that makes this type of ice has a constant harvest cycle. This cycle is maintained as long as the auger and compressor are operating.
The auger is rotated by means of a motor which has a suitable gear arrangement. This motor may be kept on the top or at the bottom of the rotating auger.
The auger is placed in a vertical position and has a shaft seal. If the motor is on top of auger, the shaft seal prevents gear oil from draining into the ice. If the gearbox is placed at the bottom of auger, the shaft seal prevents the water from entering into the gearbox.
