A hop house (also known as a hop dosser, dry hopper) is used for adding pellet hops into a closed fermentation tank without exposing the beer to oxygen. The vessel is mounted on top of the fermenter and allows controlled transfer of hops by opening the butterfly valve beneath it. This setup is typically used for dry hopping in craft breweries that want to minimise oxygen pick-up during hop additions.

Technical description:

• Designed for 4-5 kg of pellet type 90 hops.

• Connection to fermenter: 4" Tri-Clamp.

• Top lid: 8" Tri-Clamp, fitted with a handle for safe opening and handling.

• The lid includes two welded 1/4" BSP threaded ports:

  • one female thread (internal)

  • one male thread (external)
    These ports can be used for a pressure gauge, a small bleed valve for venting, or CO₂ supply.
    Pressure gauges, valves and plugs are not included.

• Compatible with fermentation tanks that have a 4" Tri-Clamp connection at the top.

• For operation, a 4" butterfly valve is required between the vessel and the tank to release hops into the fermenter.
  Butterfly valve, gasket and clamp are not included.

• Internal surface and welded connections are polished to ensure sanitary operation and easy cleaning.

This hop dosing vessel is intended for breweries that need a safe and oxygen-controlled method of introducing hops during the fermentation or dry-hopping phase.
