Cold Press Juicer Buying Guide

1. Cold Press vs. Centrifugal Juicers

1. Nutrient Retention
   • Cold Press (Slow Masticating): Low speed (≤80 RPM) minimizes oxidation, preserving more vitamins, enzymes, and antioxidants.
   • Centrifugal (High-Speed): Heat and oxidation lead to greater nutrient loss.
     *WHALL’s model operates at 74 RPM, ideal for health-conscious users.*
2. Juice Yield & Texture
   • Cold press yields ~20% more juice with drier pulp, producing richer, non-separating juice.

2. Key Buying Factors

1. Motor Performance
   • Power: 150W–200W is sufficient (WHALL uses a 150W quiet motor). Excess power may damage fibers.
   • Torque: High torque (e.g., WHALL’s 40N.m) handles hard produce (carrots, ginger) better.
2. Feed Chute Design
   • Width: ≥3 inches (WHALL’s is 3.2") reduces prep time for whole fruits/vegetables.
   • Material: Food-grade ABS or Tritan ensures safety and durability.
3. Extraction Technology
   • Auger system: WHALL’s 7-stage spiral press maximizes efficiency.
     Reverse Function: One-touch reversal (WHALL includes this) prevents jams and eases cleaning.

3. WHALL’s Standout Features

1. Smart Touchscreen
   • One-touch soft/hard modes (e.g., strawberries vs. apples) for hassle-free adjustment.
   • Real-time operation display, perfect for tech-savvy users.
2. Easy-Clean Design
   • Dishwasher-safe parts (most WHALL components are compatible).
   • Includes a cleaning brush for hard-to-reach areas.
3. Quiet & Stable Operation
   • ≤60 dB noise level (WHALL measures 58 dB) with non-slip silicone feet.

4. Materials & Safety Certifications

1. Critical Components
   • Strainer: 304 stainless steel (WHALL uses a dual-layer filter for longevity).
   • Housing: BPA-free plastic to avoid chemical contamination.
2. Certifications
   • Look for CE/ROHS/FDA marks (WHALL is certified) for electrical safety.

5. Ideal Users & Scenarios

• Best For:
  • Households (1–2 cups daily).
  • Health/diet enthusiasts (retains fiber).
  • Parents (makes additive-free baby food).
• Not For: Commercial high-frequency use (opt for industrial models).

6. Comparison with Competing Models

7. Maintenance Tips

1. Rinse residue immediately to avoid clogging from dried sugars.
2. Soak the strainer weekly in citric acid to remove mineral buildup.
3. Run water through the juicer for 5 minutes before first use to clear factory residues.

Final Verdict: WHALL’s cold press juicer excels in smart features (touchscreen) and convenience (large chute + reverse function), making it ideal for mid-budget households prioritizing ease of use. If cost is a bigger concern, opt for a basic model—but expect fewer features.
