Chapter 27, Problem 1RQ
Which type of ice maker has a continuous harvest cycle?
Expert Solution & Answer
To determine
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.

Q2. Determine the safety factors for the bracket rod shown in Figure 2 based on both the
distortion-energy theory and the maximum shear theory and compare them.
Given: The material is 2024-T4 aluminum with a yield strength of 47 000 psi.
The rod length /= 6 in. and arm a = 8 in. The rod outside diameter od 1.5 in., id = 1 in, h=2 in.,
t=0.5 in., Load F= 1000 lb.
Assumptions: The load is static and the assembly is at room temperature. Consider
shear due to transverse loading as well as other stresses. (Note: solve in SI units)
