INTRODUCTION
This document is the FDS (Functional Design Specification) for Winterization for Refined Oil (18/12 or Omega 30 %).
The purpose of this FDS is to specify design, operational and functional aspects of the system according to the requirements given in the URS-PWR.
SCOPE
The scope of this FDS is defined by the URS-PWR.
The Winterization system consists of feed tanks, crystallizers, centrifuge, olein tank and stearine tank.
The design of the Winterization for Refined Oil system is defined by the P&ID: CSL-123200-313-SC-PI-001 Rev. R1.
VALIDATION
The system will be located within a GMP compliant facility; however, it shall not be used for API production, and will have IQ (Installation Qualitification) and OQ (Operational Qualitifcation) completed. The system shall meet the requirements for food standards and hygienic design. The documentation shall comply with the principles described in the ISPE GAMP 5 guideline.
Change control shall become operative for this system when this FDS is approved and signed out by TASA Omega.
RESPONSIBILITY
Everybody involved in the project shall act in accordance with the scope, specifications and requirements of this document.
PROCESS AND OPERATIONAL DESCRIPTION
The oil shall be heated to 50 – 55 °C, and kept at elevated temperature until all solids are melted, prior to entering the crystallizer and cooled down according to a cooling curve dependent of the oil quality. Food grade propylene glycol is recirculated to cool the batch and make crystals. When the crystallization is finished the slurry shall be separated on a centrifuge. The centrifuge shall be primed with a melted stearine fraction and as soon as the feeding is started from the crystallizer the stearine feed shall stop.
Stearine will be separated and collected in a stearine melting vessel and pumped to the stearine tank. The olein phase is collected in a separate tank for approval prior to further processing.
