AF80 Ice flaker – 70Kgs/24Hrs

Scotsman AF80 Ice Flaker Detailed Summary (South Africa)

Key Specifications

• Ice Production: Up to 65–73 kg (143–161 lbs) of flake ice per 24 hours, calculated at 10°C ambient and 10°C water temperature. Production varies by source (e.g., 65 kg/24 hours per Performance Health, 70 kg/24 hours per Ice2o, 73 kg/24 hours per Scotsman SA).
• Storage Capacity: 25 kg (55 lbs) built-in, food-safe integral storage bin.
• Ice Type: Granular flake ice, 75% hardness, extruded at just below 0°C, with 25% residual water content, ideal for rapid cooling and molding to any shape.
• Dimensions:
  • Without legs: 535 mm (W) x 620–626 mm (D) x 797–813 mm (H)
  • With legs: 535 mm (W) x 620–626 mm (D) x 890–933 mm (H)
• Weight: 50–72 kg, depending on source.
• Power Requirements: 230 V, 50 Hz, single phase, ~350–450 W, 13 A plug, with average energy consumption of 7.5 kWh per 64 liters of water at 15°C.
• Refrigerant: R-134a (CFC-free) or R-290 (propane) in EcoX models, with a low global warming potential (GWP) of 3, compliant with F-Gas regulations. Some sources note a transition to R-452A for newer models.
• Condensing System: Available in air-cooled or water-cooled versions. Air-cooled models feature front-in, front-out airflow for built-in or under-counter installations.
• Water Requirements:
  • Minimum water temperature: 5°C
  • Maximum water temperature: 38°C
  • Minimum water pressure: 1 bar (14 psi)
  • Maximum water pressure: 5 bar (70 psi)
  • Water consumption: ~64 liters per 24 hours at 15°C.
• Drainage: Gravity drainage (20 mm diameter sump drain at floor level). No built-in Progressive Water Discharge (PWD) system, unlike some Scotsman models (e.g., EF series with drain pump).

Key Features

1. Flake Ice Production:
   • Produces granular flake ice (75% hardness, 25% residual water content) by freezing a thin layer of water on a horizontal evaporator drum, scraped off by a revolving auger to form flakes. Ideal for food displays (e.g., seafood), cocktails, smoothies, and medical applications like physiotherapy ice packs or organ transportation.
   • Flake ice molds easily to any shape and cools rapidly, making it suitable for fisheries, laboratories, and food processing.
2. Design and Build:
   • Grade 304 Stainless Steel Exterior: Corrosion-resistant, durable, and hygienic, ensuring longevity and a professional appearance.
   • Compact Footprint: 535 mm width allows for under-counter or built-in installations, with front-in, front-out airflow requiring no side clearance.
   • Ergonomic Access: Slanted, disappearing storage bin door with a one-touch lift for easy ice access, enhancing staff efficiency.
3. Maintenance and Hygiene:
   • XSafe Sanitation System: Integrated 24/7 natural UV-based sanitation, standard since September 2020, destroys 99% of bacteria and viruses, including COVID-19, preventing mold, mildew, slime, and odors.
   • AgION Technology: Built-in antimicrobial protection resists microbe growth and odor development in plastic components.
   • Clean Alert: External indicator lights blink to signal when cleaning is required.
   • Front-Access Condenser Air Filter: Removable and washable, recommended for monthly cleaning to maintain performance and extend machine life.
   • One-Touch Cleaning: Initiated via electronic controls, using Scotsman Ice Machine Cleaner, followed by automatic rinsing, reducing labor costs.
   • Regular Bin Sanitization: The bin interior, in contact with food-grade ice, should be cleaned and sanitized weekly with a commercial food-grade sanitizer.
4. Ease of Use:
   • Electronic Controls with Self-Diagnostic Functions: Front panel includes LEDs for reset/washing, alarm (e.g., high condenser temperature), bin full, operation, and power supply, providing early alerts and fast diagnosis of issues.
   • Five Sensors: Monitor machine health (e.g., condenser temperature, ice production), communicating with the control board to optimize energy use and protect components like the fan motor.
   • Water In/Ice Out Concept: Matches water consumption to ice production, minimizing water and energy wastage.
5. Optional Demineralization Kit:
   • Available for use with soft or deionized water, ensuring compatibility in laboratory settings (e.g., AF80 LAB model).

Applications

• Ideal for foodservice (cocktails, smoothies, seafood displays), medical (physiotherapy ice packs, organ transportation), laboratories, and food processing (preservation of perishables like fish or superfoods).
• Flake ice’s ability to mold to any shape and cool rapidly makes it perfect for fisheries, pharmaceutical applications, and high-end beverage presentation.

Operational Considerations

• Environmental Conditions: Operates effectively in ambient temperatures from 10°C to 43°C and water temperatures from 5°C to 38°C.
• Installation Requirements: Requires a permanent water supply (3/4” inlet) and gravity drainage (20 mm sump drain at floor level). Must be connected to a neutral wire and solid earth ground to prevent electrical shock or equipment damage. Not suitable for stacking.
• Recommended Water Filter: AP3S or HF20-S water filter recommended to maintain ice quality and reduce scale buildup.
• EcoX Initiative: Some AF80 models use R-290 or R-452A refrigerants, making them environmentally friendly and compliant with F-Gas regulations.
