To start busines of ice you can go with portable ice makers which are units that can fit on a countertop. They are the fastest and smallest icemakers on the market. 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. The pegs use a heating and cooling system inside to freeze the water around them and then heat up so the ice slips off the peg and into the storage bin.Ice begins to form in a matter of minutes, however, the size of ice cubes depends on the freezing cycle - a longer cycle results in thicker cubes. Portable icemakers will not keep the ice from melting, but the appliance will recycle the water to make more ice. Once the storage tray is full, the system will turn off automatically.

An ice machine, however, particularly if described as 'packaged', would typically be a complete machine including refrigeration, controls, and dispenser, requiring only connection to power and water supplies.
