80L Pressurized Yeast Storage Tank for Modern Brewing Use

Product Introduction: Pressurized Yeast Storage Tank

The pressurized yeast storage tank provides a practical solution for breweries that require controlled yeast storage, collection, cooling, and accurate dosing during fermentation. With an effective working capacity of 80 liters and a total vessel capacity of 88 liters, it accommodates yeast handling requirements in compact brewing operations.
The cylindrical tank incorporates a duplex cooling jacket that can be connected to an ice water or glycol system through hoses. This arrangement supports temperature management during yeast storage and handling. A top manhole allows convenient access for inspection and sanitation, while dedicated filling, discharge, air inlet, and outlet connections support process integration.
Designed for low-pressure operation with a maximum pressure of 0.5 bar, the vessel enables yeast dosing into fermentation tanks without requiring a dedicated transfer pump under suitable installation conditions. Its tiltable support structure allows the tank to incline up to 130 degrees in both directions, facilitating drainage of residual yeast. These features help simplify yeast handling, improve operational convenience, and support consistent fermentation preparation.

Working Principle

The yeast pressure storage tank combines low-pressure operation with jacket cooling to support yeast storage and dosing. Collected yeast enters the vessel through the designated filling connection. During storage, an external ice water or glycol supply circulates through the duplex cooling jacket to help control the tank temperature.
When yeast is required for fermentation, the vessel uses a suitable pressure arrangement to assist discharge through the designated outlet. Under compatible operating conditions, this allows yeast transfer without a dedicated dosing pump. After discharge, the tank can be tilted to facilitate drainage of residual yeast. The vessel is then inspected and cleaned according to the brewery’s sanitation procedures.

Working Process

Step 1: Yeast Collection
Collected brewing yeast is introduced into the vessel through the designated filling connection.
Step 2: Cooling Connection
The duplex cooling jacket is connected to an ice water or glycol system to maintain the required storage temperature.
Step 3: Controlled Storage
The yeast remains in the vessel under suitable operating conditions until it is needed for the next fermentation batch.
Step 4: Pressure-Assisted Dosing
The designated pressure and discharge connections are used to transfer yeast into a fermentation tank, subject to the system’s approved operating limits.
Step 5: Residual Yeast Drainage
The vessel is tilted within its designed range to facilitate drainage of residual yeast.
Step 6: Cleaning and Preparation
The tank is inspected and cleaned before being prepared for the next yeast handling cycle.

Important Factors for Selecting a Yeast Storage Tank

1. Working Capacity: Select a vessel according to the yeast quantity required for each fermentation batch.
2. Cooling Requirements: Confirm the required yeast storage temperature, available glycol or ice water supply, and cooling system capacity.
3. Operating Pressure: Ensure that the vessel’s pressure rating is compatible with the brewery’s transfer arrangement and applicable safety requirements.
4. Connection Compatibility: Check filling, discharge, air, and cleaning connections against the existing brewery piping.
5. Cleaning and Sanitation: Verify that the vessel design and cleaning procedures meet the brewery’s hygiene requirements.
6. Installation Space: Allow sufficient clearance for pipe connections, manhole access, maintenance, and the tank’s permitted tilting movement.

FAQ

Q1: What is the working capacity of the yeast pressure storage tank?
A: The effective working capacity is 80 liters, and the total vessel capacity is 88 liters.
Q2: What is the maximum operating pressure?
A: The specified maximum pressure is 0.5 bar. The vessel must be operated within its approved pressure limits.
Q3: How is the yeast tank cooled?
A: A duplex cooling jacket connects to an external ice water or glycol system through hoses.
Q4: Can yeast be transferred without a pump?
A: Yes. The pressure-assisted design supports pump-free dosing when the installation, pressure differential, and receiving vessel conditions are suitable.
Q5: Why does the tank have a tilting structure?
A: Tilting helps drain residual yeast and facilitates emptying and cleaning. The specified inclination is up to 130 degrees in both directions.
Q6: Can the tank be connected to an existing brewery system?
A: Integration depends on the existing pipework, connection sizes, pressure arrangement, and cooling supply. These details should be confirmed before installation.
Q7: Is the tank suitable for every type of yeast?
A: Suitability depends on the yeast strain, storage temperature, storage duration, and process requirements. These conditions should be reviewed before selecting the vessel.
