I. Problem: Before Buying a Flake Ice Machine, Answer These Three Questions

Many aquatic product wholesalers and food processing plants, when purchasing flake ice machines, ask right away, “How many tons do I want to buy?” The result is often: buy too small, and there is not enough ice during peak periods; buy too large, and equipment sits idle while electricity bills are wasted. The essence of flake ice machine selection is not choosing “large” or “small,” but matching daily output, storage capacity, and usage scenario as a trio.

II. Cause Analysis: Three Common Causes of Selection Mistakes

1. Focusing only on daily tonnage and ignoring peak demand: The daily output of a flake ice machine is calculated based on 24-hour continuous operation, while actual ice usage is often concentrated in two peaks, morning and evening; peak hourly ice usage can reach twice the average.
2. Ignoring on-site power supply conditions: Small machines can use 220V single-phase power, but once daily output exceeds 0.5 tons/day, most models require 380V three-phase power. Many customers only discover after installation that the electrical modification cost far exceeds expectations.
3. Choosing the wrong air cooling vs. water cooling: Air cooling is simple to install and requires no cooling tower, but in high summer temperatures, condensing pressure is high and ice output decreases; water cooling provides stable ice output but requires a cooling water system, making it suitable for factories with water source conditions in the workshop.

III. Principle: How a Flake Ice Machine Works

A flake ice machine uses a refrigeration system to maintain an evaporation temperature of around -20℃; water rapidly freezes on the surface of a rotating evaporator (ice drum), and is then continuously scraped off by an ice-scraping blade to form thin flake ice with a thickness of 1–3mm. Flake ice has a large contact area and cools quickly, making it an ideal ice for preserving seafood and meat. The equipment’s standard operating conditions are an ambient temperature of 25℃, inlet water temperature of 15℃, and condensing temperature of 40℃. Actual ice output decreases as ambient temperature rises; during selection, reserve a 15%~20% margin according to local summer high-temperature conditions.

V. Three-Step Selection Method

1. Calculate daily usage: Count the single-day peak ice usage during peak season, multiply by a safety factor of 1.2–1.3, and obtain the target daily output tonnage.
2. Determine cooling method: Choose water cooling if there is a cooling tower or water source conditions; choose air cooling if space is limited and simple installation is desired.
3. Verify basic conditions: Power supply (220V/380V), site dimensions (including ice storage bin footprint), and refrigerant (R404A is the current mainstream).

VI. Frequently Asked Questions (FAQ)

Q1: Is 220V household power enough for a 0.2-ton small machine? A: Yes. The LR-02T has a total power of only 1.1kW and can be used immediately with a 220V single-phase power supply, suitable for supermarkets, milk tea shops, and small restaurants. However, models above 0.3 tons usually require 380V three-phase power; be sure to confirm the site power supply before purchasing. Q2: Will an air-cooled flake ice machine produce insufficient ice in summer? A: It will decrease. The standard conditions are an ambient temperature of 25℃ and water temperature of 15℃; in a 40℃ summer environment, ice output may decrease by more than 20%. In high-temperature areas, it is recommended to choose one size larger or switch to water cooling. Q3: What is the difference between flake ice, block ice, and tube ice? A: Flake ice is 1–3mm thick, has a large contact area, and cools quickly, making it suitable for rapid preservation of seafood and meat; tube ice and cube ice melt slowly and look good, making them suitable for beverages and display purposes. Different ice usage methods require completely different selection. Q4: How should the ice storage bin capacity be matched? A: Ice storage bin capacity is generally configured at 0.5–1 times the daily output to buffer peak periods. Taking the LR-1T as an example, the standard ice storage bin is 1100×900×1080mm and can store about half a day’s output. Q5: How to choose between R22 and R404A refrigerants? A: R22 is an older refrigerant, still used only in some low-power models; for newly purchased equipment, R404A is recommended because it has better environmental compliance and is also the standard configuration of mainstream models.

Q6: How much installation space must be reserved for a flake ice machine? A: In addition to the main unit, space must be reserved for an ice storage bin, maintenance access, and heat dissipation. Small machines require about 2–3 square meters, medium machines 4–6 square meters, and large machines must be confirmed according to actual drawings; water-cooled models also require space reserved for a cooling tower.

7. Summary

The core of flake ice machine selection is to “speak with data”: first calculate peak ice usage, then determine tonnage; first review site conditions, then decide air-cooled or water-cooled; first verify power supply and refrigerant, then discuss price.
