You don't think about ice until you run out — and then it's a crisis. A commercial ice machine produces hundreds of pounds of ice daily and is one of the highest-maintenance pieces of equipment in a kitchen. Water quality determines everything about reliability and ice quality.
Cubed (full/half dice): Standard. Melts slowly, good for beverages. Clearer = better water filtration. Flake: Soft, chewable, molds to shape. Seafood displays, healthcare, blended drinks. Melts faster than cubes. Nugget (Sonic-style): Chewable, absorbs drink flavor. Cult following. Higher maintenance than cube. Gourmet: Clear, hard, slow-melting. Upscale bars and restaurants.
Ice machines are rated in pounds per 24 hours — but that's at ideal conditions (70°F air, 50°F water). Real-world output is 70-80% of rated. 100-200 lbs/day: Small bar, cafe. 300-500 lbs/day: Medium restaurant. 500-1000 lbs/day: High-volume, hotel, banquet. The bin should hold roughly 50-80% of daily production.
This is not optional. Hard water destroys ice machines — scale buildup on the evaporator plate reduces output and eventually kills the machine. Install a proper filtration system (not just a taste filter) that removes sediment and reduces scale. Budget $200-500 for the filter system. The cost of not doing it is replacing the machine in 2-3 years.
Ice machines need regular cleaning and sanitizing — health departments check them. You'll need to descale (remove mineral buildup) and sanitize (kill mold/slime) at minimum every 6 months, more in hard water areas. Self-cleaning features help but don't eliminate manual cleaning. Budget for professional service unless someone on staff is trained.
Budget ($300-800 used): Manitowoc (older Indigo series), Ice-O-Matic. Decent if maintained.
Mid-Range ($800-2000 used): Hoshizaki (the reliability king), Scotsman Prodigy. Worth the premium for uptime.
Premium ($2000+): Hoshizaki KM, newer Manitowoc NEO. Best warranty, easiest to service.
