Product catalog summary
Overview of Yeast Propagator
The Yeast Propagator is a system consisting of one or more individually controllable propagation tanks. The number and size of these tanks are determined by the brewery's capacity and processes. The yeast propagation process involves filling the propagator with a yeast suspension and mixing it with fresh wort until the desired yeast quantity and cell concentration are achieved. The mixture is aerated and gently recirculated to ensure homogeneity. Oxygen or sterile air is used for aeration, and the O2 content is continuously monitored by a high-precision OXYTRANS sensor from Centec. This setup ensures the production of vital and healthy yeast cells with nearly 100% viability, which can be used for fermentation or further growth in other propagators. The system's components are designed to treat yeast gently, preserving cell viability and vitality.

Yeast Propagator-1

The Process Technology Company. Yeast Propagator Propagation of Yeast (Yeast Management) Propagation von Hefe (Hefemanagement) The Yeast Propagator consists of one or more individually controllable propagation tanks. The number and the size of these propagators relates to the brewery’s capacity and the processes. For yeast propagation the yeast suspension is filled into the propagator and mixed with fresh wort until the desired yeast quantity and cell concentration are reached. At the same time the mixture is aerated and gently recirculated to achieve homogeneity. Inside the propagator the yeast cells grow in sterile environment. For aeration oxygen or sterile air is used. The O2 content is permanently monitored using a high precision optical OXYTRANS sensor made by Centec. Ideal and stable conditions inside the propagation tank result in vital and healthy yeast cells with nearly 100 % viability. The yeast cells can be pitched into the wort stream for fermentation, or they are transferred to other propagators for further yeast growth. All yeast pumps and components in the system are designed for very gentle yeast treatment, so as to fully preserve the viability and vitality of the yeast cells. Der Yeast Propagator besteht aus einem oder mehreren, individuell regelbaren Propagationstanks. Die Anzahl und Größe dieser Propagatoren steht in Bezug zur Kapazität der Brauerei und den Prozessen. Zur Hefepropagation wird die Hefesuspension in den Propagator gefüllt und mit frischer Würze gemischt bis die gewünschte Hefemenge und Zellkonzentration erreicht sind. Gleichzeitig wird die Mischung belüftet und schonend in Umlauf gebracht, um Homogenität herzustellen. Innerhalb des Propagators vermehren sich die Hefezellen in steriler Umgebung. Zur Belüftung wird Sauerstoff oder Sterilluft verwendet. Der O2 Gehalt wird permanent überwacht durch einen hoch genauen optischen OXYTRANS Sensor von Centec. Ideale und stabile Bedingungen im Propagationstank führen zu vitalen und gesunden Hefezellen mit nahezu 100 % Lebensfähigkeit. Diese Hefezellen können in den Würzefluss dosiert werden zur Fermentation oder sie werden in die anderen Propagatoren transferiert für weiteres Hefewachstum. Alle Hefepumpen und Komponenten im System sind auf sehr schonende Hefebehandlung ausgelegt, um die Lebensfähigkeit und Vitalität der Hefezellen vollstä
