Ice machine sizes are stated as the amount of ice that they can produce in a 24 hour period. This is called the "24 hour yield" or "ice yield" of the ice machine. Different types of ice machines yield different amounts of ice. Small undercounter or countertop machines may provide as little as 50 lb. of ice in 24 hours, just enough for a small beverage station in an office setting. On the other hand, large 48" wide modular units can produce as much as 2500 to 3400 lb. of ice per machine per day.
