Fermentation tank

Fermentation tank

Terlet’s fermentation tank is ideal for fermenting milk in a low-spore environment to prepare yoghurt or rennet. After the desired level of acidity is reached, the yoghurt or rennet is effectively stirred to add and mix the separated whey quickly.


Beneficial tank design

The fermentation tank (to e.g. prepare rennet and yogurt) is fit for a slight overpressure of sterile air to prevent disruption by infection of outside phages or bacteria. The stainless steel stirring mechanism has blades that help to produce both axial and radial flow movements of the rennet or yogurt.

The gate stirring device is entirely produced of solid stainless steel, which applies both the shafts and the stirring blades. Because of this, problems that arise from product remnants being left behind are prevented. This could happen if tubular materials (in stead of solid steel) are used and holes are created by corrosion.


Features and benefits

In general, the fermentation tank offers the following benefits:

  • Very even and effective cooling
  • Optimum mixing action
  • Hygienic design
  • Stirring mechanism completely made to measure for the process.
  • C.I.P cleaning possible

Yogurt tank specific advantages

This type of tank is a perfect yogurt tank. An extremely even flow is realized when stirring the final product, keeping the structure intact. Besides, the yogurt tank is equipped with a stirring mechanism completely made-to-measure to process yogurt.

Culture tank specific benefits

Being a culture tank, a smooth rennet is produced because of the effective stirring movements. Even cooling and heating is achieved in this type of tank. 

The gate stirring device consists of a number of pressing paddle blades in combination with offset vertical blades. The blades are linked to each other with rods to ensure proper cleaning. The stirring blades help to produce both axial and radial flow movements of the rennet in the product, so that a smooth rennet is created by the effective stirring action. More specifically about the stirring movements:

  • The pressing and scooping bottom blade produces turbulence over the bottom.
  • Both uppermost scooping blades produce an axial stirring action.
  • The offset vertical blades, which are directed inwards, produce both the axial and radial flow movements.
