Used Fermenters

Overview

Fermenters are vessels where wort transforms into beer under controlled temperature, pressure, and sanitation. They range from small pilot tanks to large production cylindroconicals and pressure-rated units for carbonation. Key choices include material, cooling (jacketed vs. glycol coil), valve and sampling fittings, and surface finish. Buyers prioritize easy cleaning (CIP), reliable temperature control, sanitary fittings, and access for yeast handling and maintenance.

FAQ

How do I choose the right fermenter size and type?

Match fermenter capacity to your batch size plus headspace (typically 10–20% extra). Choose cylindroconical for easy yeast harvesting, open tanks for certain mixed ferments, and pressure-rated tanks if you plan to carbonate in-tank.

What materials and finishes should I look for?

Stainless steel 304 or 316 is standard. Look for a smooth internal finish (low Ra), sanitary tri-clamp fittings, and food-grade welds. 316 is preferred for aggressive acids or long-term corrosion resistance.

How are large fermenters shipped and installed?

Clean and drain the tank, secure manways and fittings, and palletize or crate as needed. Heavy units often require a crane or forklift and may be shipped on skids. Confirm weight, dimensions, and lifting points with the carrier and insure the load.

Do used fermenters need inspection or certification before use?

Yes—pressure-tested and leak-checked if pressure-rated, visual weld inspection, sanitary surface check, valve/function test, and passivation if required. Keep records of any repairs or tests.

What is the recommended maintenance and cleaning routine?

Use CIP with caustic then acid cycles, rinse thoroughly, and sanitize before use. Regularly inspect and replace gaskets, check valves and seals, clean thermowells and probes, and maintain glycol jackets and pumps.

Which spare parts and accessories should I buy with a fermenter?

Keep spare tri-clamp gaskets, sample and racking valves, pressure relief valves, sight glass, spare thermowell probes, and replacement seals for any sanitary fittings.
