Yeast Pitching

The intelligent combination of a frequency-controlled pump and a controlled overflow valve allows the compensation of variations in yeast consistency and wort flow rate

The method GEA developed to determine the yeast cell count through differential turbidity measurement ensures accurate yeast pitching. Variations in the basic turbidity of the wort are compensated for. A static mixer developed especially for this application provides proper mixing of the yeast into the wort. As an alternative to differential turbidity measurement, the yeast volume can also be determined by a viable cell count.

Yeast quality – our conclusion

Design

  • Function-tested units preassembled on a compact base frame
  • Use of VARIVENT® components for highest hygienic standard and best CIP ability
  • Individual units can be upgraded from the simplest to the most powerful version welding and cutting work
  • Capacity adjustment by exchanging parts with detachable connections within the range of nominal widths DN 50 – DN 125.

Technical data

  • Integration of a serial interface for linking the line to a master control system
    Separation of wort and yeast pipe by VARIVENT® mixproof or normal shut-off valves
  • Differential turbidity measurement, based on the correlation between turbidity and yeast cell count
  • Control of the added viable cell count by measuring the electrical properties of intact cell membranes
  • Sizes (wort pipe): DN 50 to DN 150 (6“)
  • Wort flow velocity: 1.0 – 2.5 m/s
  • Wort pressure: yeast pitching unit max. 6.0 bar
  • Pressure drop in the wort pipe: yeast pitching unit < 0.5 bar
  • Yeast pitching range: 5 – 50 million yeast cells / ml wort
  • Nominal width of yeast pipe: DN 40 to DN 80
  • Supply pressure of the pitching yeast:
    > 0.5 bar above the CO² saturation pressure
    > 0.5 bar under the wort pressure at the dosing
  • Product flow rate: up to 1900 hl / h.

Dear partners,

We would like to inform you that in the framework of preventive measures aimed at effectively addressing the spread of “Covid19” disease and in accordance with the National Public Health Organization guidelines (https://eody.gov.gr/), our company is committed to ensure public health, safety of its partners and employees. Therefore we have recommended the fulfillment of our employees' tasks through teleworking.

The duration of this measure is initially set from 17.03.2020 to 30.04.2020

The design provides full operation, but due to special conditions, delays in specific tasks or communication may occur.

Our company will strive to keep its operation uninterrupted and secure by serving its clientele in ways and timeframes that are judged possible.

We thank you for understanding and we remain at your disposal.


Αγαπητοί Συνεργάτες,

Θα θέλαμε να σας ενημερώσουμε ότι στο πλαίσιο μέτρων πρόληψης με σκοπό την αποτελεσματική αντιμετώπιση εξάπλωσης του κορωνοιού και σύμφωνα με τις οδηγίες υγιεινής & ασφάλειας που έχει ορίσει ο ΕΟΔΥ (https://eody.gov.gr/), η εταιρία μας για να διασφαλίσει τη δημόσια υγεία, την ασφάλεια των συνεργατών και των εργαζομένων της, συστήσαμε την εκπλήρωση των καθηκόντων των εργαζομένων μας, μέσω τηλεργασίας.

Η διάρκεια του συγκεκριμένου μέτρου ορίζεται αρχικά από τις 17.03.2020 έως τις 30.04.2020

Ο σχεδιασμός προβλέπει πλήρη λειτουργία, ωστόσο εξαιτίας των ειδικών συνθηκών, ενδέχεται να παρουσιαστούν καθυστερήσεις σε συγκεκριμένες εργασίες ή και στην επικοινωνία.

Η εταιρία μας θα προσπαθήσει να διατηρήσει αδιάληπτη και ασφαλή την λειτουργία της, εξυπηρετώντας το πελατολόγιο της με τρόπους και σε χρονικά πλαίσια που κρίνονται δυνατά.

Σας ευχαριστούμε για την κατανόηση και παραμένουμε στην διάθεση σας.
