The ice produced by a portable icemaker is bullet-shaped and has a cloudy, opaque appearance. The first batch of ice can be made within 10 minutes of turning the appliance on and adding water. The water is pumped into a small tube with metal pegs immersed in the water. Because the unit is portable, water must be filled manually. The water is pumped from the bottom of the reservoir to the freeze tray.

In the process, tiny air bubbles get trapped, causing the cloudy appearance of the ice. However, most under-counter ice makers are clear ice makers in which the ice is missing the air bubbles, and therefore the ice is clear and melts much slower. </p> <div class="mw-heading mw-heading2"><h2 id="Industrial_icemakers">Industrial icemakers</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Icemaker&action=edit&section=8" title="Edit section: Industrial icemakers"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Commercial ice makers improve the quality of ice by using moving water.

The water tray at the bottom catches the cold water while deflecting Ice and re-circulates it back into the sump. The sump will typically use a float valve to fill as needed during production. Flake machines have a tendency to form an ice ring inside the bottom of the drum. Electric heaters are in wells at the very bottom to prevent this accumulation of ice where the crusher does not reach. Some machines use scrapers to assist this.
