Yeast Management System

Hypro complete solution for Yeast Management including Yeast Propagation, Storage & Pitching Systems are designed with hygienic aspects as a focus and offer the Brewer a plant and its ancillaries which can be effectively CIP and keep contaminations at bay. The Yeast Storage Systems are equipped with agitation at low speeds to avoid shear damage to the yeast cells. Gravimetric pitching is provided as a standard.

 

 

Product Description

Yeast Propagation Plant & Yeast Storage Vessel are built with utmost consideration of hygienic design and construction. St St 304 L is the material that is used and the surface is finished to < 0.6 uRa on our automatic polishing machines. The tank is equipped with CIP'able safety fittings; adequate instrumentation level for consistent output coupled to PLC based automation. The design and construction of the vessel and associated pipework ensures contaminations cannot occur.

Features

  • Consistent vitalization of the yeast
  • Maximum yeast viability
  • Gentle homogenization
  • Optimal aeration rates
  • Temperature control

Functionality

 

The Yeast Propagator is either single stage or two stages. The Yeast Propagator cooling and heating system are designed to the pre-defined wort volumes thus facilitating sterilization of wort and its rapid cooling. For propagation of yeast, the propagator is aerated with sterile air by way of sparging inside the vessel or externally during circulation. Internal Air sparger is an easily removable type with CIP/SIP. To accelerate and promote propagation the wort is circulated within the vessel.

 

The yeast is chilled on line during cropping prior to storage. The cooling system is designed for facilitating its further cooling if needed and to maintain the yeast temperatures during storage. For homogenization of yeast the mass is circulated inside the vessel.

Advantages

  • Gravimetric measurement of Mass
  • Yeast cell concentration measurement and monitoring
  • Automatic polishing machines
  • Easy and effective CIP operation
  • Lower operating cost

 Often combined with

Hypro has successfully installed more than 20 Yeast Management System to date around the world and numbers are growing. Yeast Propagation & Storage Plant is best combined with Industrial Brewery and CO2 Recovery System in order to recover the CO2 which is the by-product of the yeast fermentation.

 

Product FAQs

Yeast is generally acid-tolerant and therefore grow at lower pH level. Best suitable pH range of yeast is between 4-4.5.

Fermentation rate is affected by variety of factors like nutrient availability & concentration, pH level, temperature etc.

Yeast fermentation is at its best at temperature range of 90-95 F i.e. 32- 35 deg C. Every degree above this range is hazardous during the later stages of fermentation.

Yeast flocculation is desirable characteristics as the yeast cells aggregate into clumps forming multi-cellular mass and sediment at the bottom of the fermentor which in turn results in the clear beer with a desirable flavor.
