LYOSENSE® for Online Moisture Control
LYOSENSE® from GEA, based on multipoint NIR measurements, provides the comprehensive and non-destructive evaluation of freeze-dried product cakes in real-time.
The lyophilization of pharmaceutical products such as vaccines enhances their stability and shelf-life. However, these properties can only be maintained when the resulting cake has a residual water level of 0.2–5.0%.
For this reason, regulatory guidance indicates that this parameter must be controlled and determined. Until now, however, techniques to measure such properties have been both destructive and time-consuming, and therefore uneconomical.
Our GEA LYOSENSE® sensor uses multipoint NIR measurements to comprehensively and non-destructively evaluate freeze-dried product cakes in real-time. This easy-to-install and use online measuring device is a fast and a non-invasive solution to moisture determination, enabling the effortless detection of residual moisture.
The LYOSENSE® STATION was designed for the quick, accurate and mobile testing of pharmaceutical glass vials for residual moisture. Mounted on wheels for easy maneuverability, the LYOSENSE® STATION is 900 mm wide and can readily pass through the doors and corridors of most pharmaceutical production areas.
The LYOSENSE® and LYOSENSE® STATION automatically measure the residual moisture content in lyophilized glass vials, which are manually loaded via a tray on the infeed turntable. Process parameters such as vial speed can be controlled using an integrated touchscreen and residual moisture limits can be controlled by a laptop via an interface. Checked vials are stored on the outfeed table and can be collected manually on the infeed tray.
The NIR sensors measure the vials from the side and/or from below. The results are sent to an external computer, which is isolated from the process area and reports any out-of-specification data. Rejected vials are collected in a container adjacent to the conveyor.
This miniaturized probe is simple to calibrate and enhances product development by facilitating Quality by Design. It also offers the following benefits:
Our LYOSENSE® products are verified before delivery in a factory acceptance test (FAT). The results comprise part of the documentation package. Designed to comply with the European Union’s CE Guidelines, they are supplied with a manual, safety instructions and wiring diagram.
GEA’s LYOVAC® industrial-scale freeze dryers are built to customer specifications and are available with production areas of 1–60 m² and condenser capacities of more than 1000 kg.
ALUS® Automatic Load & Unload Systems minimize the risk of operator/product contamination while loading and unloading a freeze dryer.
質の高いコールドチェーン管理の重要性を過小評価することはできません。傷みやすい生鮮食品が消費地で安全かつ高品質であることを保証することは、コールドチェーン施設を運営する人々にとって非常に大きな責任です。GEAは、低温貯蔵や配送センター向けに安全で持続可能な冷凍技術を提供する最前線に立ち、お客様の施設のエネルギー消費量と二酸化炭素排出量の削減を支援しています。
自動搾乳における最新の進化は、バッチ搾乳を導入することです。バッチ搾乳とは、通常1日に2~3回、決まった搾乳時間に乳牛をグループ分けして搾乳する酪農方法です。自動化技術は、酪農場における乳牛の福祉、柔軟性、そして持続可能性のバランスを取りつつ、それと同時にコスト構造を継続的に最適化し、より効率的になるという、酪農家の最近の課題を克服するのに役立っています。
多数の国では、安全な水と衛生設備を確保することがいまだに課題となっています。汚れの混じった飲用水により病気になったり、毎日水を汲みに行くという役割を果たすため、学校に通うことができない子供たちが多数存在します。ドイツのハンブルクを拠点とする非営利団体Viva con Aguaと協力することで、GEAは一部のタンザニアの学校にきれいな水を供給する手助けをしています。
