Definitions

  • Food work pieces are often treated with antimicrobial solutions to kill or control microbial populations that may otherwise deleteriously affect the food product.
  • This disclosure relates to antimicrobial application methods and systems, and more particularly to a Peragonn antimicrobial application method and system with improved pH monitoring for use in connection with food work pieces and surfaces and other items associated with food processing.
  • the methods involve monitoring amounts of water and acid supplied to a system, and storing the starting volume and pH of the antimicrobial solution, and storing a running average of the volume of acid delivered per pump stroke, and calculating the strength of the solution based on the monitored original and added amounts of water and acid, together with the running average stroke volume of acid previously supplied to the system, which are representative of the strength of recycled aqueous antimicrobial solution. Amounts of acid added the system can be automatically adjusted in real time to maintain a desired strength of the antimicrobial solution.
  • the systems include modular monitors that can be used to measure the inputs to the system, and which can be separately installed and maintained.
  • a chicken carcass is first plucked, washed, cut into pieces and then put onto a conveyor belt.
  • the chicken pieces travel into a dip tank 10 and pass through an antimicrobial solution 20.
  • the antimicrobial solution 20 may be continually topped up in the tank from nozzles 30, or any suitable mechanism.
  • the base of the dip tank 10 can include a recycling tank 40 into which the antimicrobial solution is pumped after having been initially filtered with a large mesh.
  • the liquid from the recycling tank 40 is then passed via a conduit 50 to a sanitizer 60 where it is filtered and passes through a UV light sterilizer and is reused by being returned to the spray nozzles 30 and mixed with fresh antimicrobial solution.
  • Chicken pieces typically enter the dip tank 10 with water on them from the washing step that follows the plucking step. This water tends to come off the work pieces and be recycled into the recycling tank 40 along with the antimicrobial solution 20, which tends to dilute the acid antimicrobial solution. Also, as the chicken carcasses or work pieces are dipped or sprayed, some of the acid adheres to the carcass or piece itself and also to particles that fall from the carcasses and are filtered out. This additionally tends to dilute the acid solution.
  • computer-readable memory media may include any memory medium capable of being a memory for electronic data representative of data or computer instructions stored, communicated or processed in accordance with embodiments of the present invention. Where applicable, method steps described herein may be embodied or executed as computer instructions stored on a computer-readable memory medium or media.

Abstract

La présente invention concerne des procédés et des systèmes pour déterminer la concentration, et donc le pH, d'une solution antimicrobienne aqueuse pour le traitement de pièces de travail d'aliment. Les procédés mettent en œuvre le stockage de la quantité de départ originale et de la concentration d'eau et d'acide de la solution antimicrobienne, la surveillance des quantités d'eau et d'acide fournies à un système, le stockage d'une moyenne du volume d'acide distribué par course de pompe, et le calcul de l'activité de la solution sur la base des quantités surveillées conjointement avec le volume de course moyen d'acide précédemment fournies au système qui sont représentatives de l'activité de la solution antimicrobienne aqueuse recyclée. Les quantités d'acide ajoutées au système peuvent être automatiquement ajustées en temps réel pour maintenir une activité souhaitée de la solution antimicrobienne. Les systèmes comprennent des débitmètres modulaires et des pompes qui peuvent être utilisés pour mesurer les entrées dans le système, et qui peuvent être installés et maintenus séparément.
