Working Principle Of The Wort Grant

In recent years, more and more customers prefer to equip their brewing systems with wort tanks, especially for larger capacity breweries.

tanks are also known as buffer tanks.
As we all know, in a brewing system, the wort aid is usually located below thefermenter. During the wort emergence process, the wort will first enter the buffer tank by gravity rather than by pump. This will ensure smooth wort drainage and avoid over tightening the grain bed.

The wort will then be transferred back to the /fermenter via the pump. It is advisable to equip the wort grant with an automatic level control system. The pump will automatically turn on when the tank is filled with a large amount of wort. If there is not enough wort in the tank, it will stop automatically.

However, if there is no automatic control system, it may be necessary for the brewer to check the wort frequently and control the pump by hand. Typically, a valve will be installed between the wort grant and the pump.

Yeast propagation and growth

Yeast propagation and growth can be divided into six stages.

1) Adjustment stage
This stage, also called the initial stage, is the activation process of fermentation. This stage fluctuates considerably. It depends mainly on the type of organism, culture generation and conditions, etc. Once the cells start to separate, it means the end of the phase.

2) Acceleration phase
This stage is immediately adjusted and separation becomes faster.

3) Growth phase
In this phase, cells multiply logarithmically with maximum and stable speed. A new generation can be produced in the shortest possible time. Usually, under good conditions, the generation time is 90-120 minutes.

4) Deceleration period
Growth is inhibited due to many factors such as decrease in substrate and increase in metabolites. During the growth period there is a certain time limit, then the growth rate is reduced.

5) Stabilization period
The number of microorganisms in this stage is stable. The number of new cells is equal to the number of dead cells.

6) Death phase
In this stage, the number of dead cells is higher than the number of new cells and the number is less.
