450L Yeast Propagation System for Mobile Brewery Operations

Product Introduction: 450L Yeast Propagation System

The mobile yeast propagation station is designed to revitalize dry yeast and prepare active yeast cultures for beverage fermentation. With a 450L tank, it integrates temperature regulation, yeast circulation, oxygen supply, and automatic nutrient management into one compact processing unit.
During operation, the tank heats the water to a preset starting temperature before yeast is introduced. A membrane circulation pump gently moves the mixture to disperse yeast clumps and maintain uniform conditions. Oxygen is supplied during circulation, while measured additions of wort or must provide nutrients for yeast development. Controlled cooling helps bring the mixture toward the required target temperature without sudden temperature changes.
A programmable controller allows operators to adjust starting and target temperatures, yeast concentration settings, and process timing. The stainless steel vessel, cooling jacket, automatic heating system, and integrated control cabinet support repeatable preparation cycles. Mounted on a wheeled frame, the station can be repositioned to suit different production arrangements. It is suitable for breweries, cider makers, wineries, and other beverage producers seeking more consistent yeast preparation, reduced handling effort, and improved fermentation reliability.

Working Principle

The mobile yeast propagation station works by combining controlled temperature adjustment, gentle circulation, oxygen supply, and nutrient addition to prepare yeast for fermentation.
First, water inside the tank is heated to the preset starting temperature. Once the target is reached, the operator introduces yeast according to the selected preparation procedure. The circulation pump moves the mixture through the system, helping disperse clumps and maintain uniform conditions.
Oxygen is supplied during circulation, while wort or must is added gradually to provide nutrients. The system manages the temperature profile through electric heating and the cooling jacket, helping prevent sudden temperature changes during the process. Operators can configure the required settings through the programmable controller.
After the yeast mixture reaches the specified preparation conditions, it is transferred to the target fermentation vessel. The station can then be cleaned and prepared for the next cycle.

Operating Process

Step 1: Initial Setup
Inspect the tank, circulation pump, water supply, oxygenation system, and transfer connections. Select the process settings required for the yeast strain.
Step 2: Water Heating
Fill the tank with the required water volume and heat it to the configured starting temperature.
Step 3: Yeast Addition
Introduce the dry yeast or yeast culture according to the manufacturer’s recommended preparation procedure.
Step 4: Circulation and Dispersion
Activate the circulation pump to gently move the mixture and help disperse yeast clumps.
Step 5: Oxygenation and Nutrient Addition
Supply oxygen and gradually introduce suitable wort or must according to the programmed process requirements.
Step 6: Temperature Regulation
Use the heating and cooling functions to guide the mixture toward the required target temperature while avoiding abrupt temperature fluctuations.
Step 7: Transfer to Fermentation
Transfer the prepared yeast mixture to the designated fermentation vessel when the required preparation conditions have been achieved.
Step 8: Cleaning and Reset
Clean the tank and associated product-contact lines using an appropriate cleaning procedure before the next production cycle.
