Comprehensive Analysis of Beer Brewing Equipment Materials

Main Material Types

1. Stainless Steel

• 304 Stainless Steel: The most commonly used food-grade stainless steel, offering excellent corrosion resistance and mechanical properties.

• 316 Stainless Steel: Contains molybdenum for enhanced corrosion resistance, particularly suitable for highly acidic environments.

• 430 Stainless Steel: Lower cost, but with poor corrosion resistance, mostly used for non-critical components.

2. Copper

• A common material used in traditional brewing, offering excellent thermal conductivity.

• It can promote certain chemical reactions and affect beer flavor.

• It requires regular polishing and maintenance to prevent oxidation.

3. Plastics

• HDPE (High-Density Polyethylene): Commonly used in fermentation vats and storage containers.

• PET (Polyethylene Terephthalate): Used for disposable fermentation containers.

• Please note food-grade certification and temperature range.

Equipment Component and Material Correspondence

Saccharification Equipment:

• Typically uses 304 or 316 stainless steel.

• Heating elements are often copper or stainless steel.

Fermentation Tanks:

• Commercial-grade equipment is often stainless steel.

• Household-grade equipment is often made of plastic or stainless steel.

Cooling System:Plate heat exchangers are often made of stainless steel.

• Cooling Coolers are often made of copper or stainless steel.

Piping System:

• Stainless steel is the mainstream.

• Some traditional breweries still retain copper piping.

Material Selection Considerations

Maintenance and Cleaning Notes

Stainless Steel Equipment:

• Regularly use an alkaline cleaner.

• Avoid chlorine-based disinfectants to prevent pitting.

• Inspect welds and seals.

Copper Equipment:

• Polish regularly.

• Use a specialized cleaning agent.

• Be aware of the toxicity of copper oxide.

Plastic Equipment:

• Avoid high-temperature sterilization.

• Inspect for scratches and aging.

• Replace regularly to prevent oxygen infiltration.
