The ice storage capacity that you need is the amount required for your daily ice usage.
Calculate the ice consumption by considering your daily customer count. The average ice consumption per customer is approximately 1.5 pounds (0.68 kg) in restaurants, 3 pounds (1.36 kg) in bars, and 5 pounds (2.26 kg) in hotels and supermarkets. So, if your guest count is 400, your daily ice consumption will be around 600 lbs (272.15 kg). Therefore, you should consider investing in an 800 lbs (362.87 kg) ice maker for your establishment, taking into account the potential melting and production losses. Then, calculate your hourly needs since the customer or guest count fluctuates. Ice makers with bins have their ice bins and help you maintain a steady stock of ice throughout the day.
