1. Key Features to Consider
Material & Safety
Stainless Steel Grade:
304 (18/8): Most common, corrosion-resistant, food-safe (meets FDA/GB 4806.9 standards).
316 (18/10): Higher corrosion resistance (ideal for salty/sour foods), more expensive.
Avoid 201 or non-food-grade steel (prone to rust).
Insulation Layer:
Vacuum insulation: Best performance (up to 24 hours), lightweight but costly.
Polyurethane foam: Affordable, thicker walls, slightly heavier.
Sealing: Food-grade silicone gasket, leak-proof design.
Capacity
36L: Suitable for 20–30 people (e.g., 15–20L of soup or 50–60 cups of drinks).
46L: For 30–50 people; note weight (~20kg when full)—opt for wheels/handles.
2. Thermal Performance
Hot Retention: Keeps liquids ≥70°C for 6–12 hours (depends on ambient temperature).
Cold Retention: Maintains ice for 12–24 hours.
Pro Tip: Pre-heat/pre-chill the bucket with boiling water/ice for better results.
3. Design & Usability
Wide Mouth (≥20cm): Easy to fill, clean, and scoop contents.
Accessories:
Tap/Spigot: For easy dispensing (ideal for drinks).
Handles/Wheels: Essential for 46L models.
Lid Lock: Prevents spills during transport.
Shape:
Vertical: Saves space.
Horizontal: Easier to scoop from (common for rice/solid foods).
