Title:
生産物をフリーズドライする方法と装置
Document Type and Number:
Japanese Patent JP2007524066
Kind Code:
A
Abstract:
The invention relates to a method and to a device for freeze-drying products using a chamber (1) having surfaces (2), whose temperature can be regulated, and condensation surfaces (5). Water penetrating from the product in the form of vapour condenses on the surface of the condensation surfaces, and measurements are taken on the documentation of the process during the freeze-drying process. The aim of the invention is to improve the freeze-drying process in relation to the documentation thereof and, at the same time, to reduce technical complexity of the device which is suitable for carrying out said method. As a result, running of the vapour flow is determined between the product and the condensation surfaces (5) and the amount of water penetrating from the product in the form of vapour is calculated by means of temporal integration.
