Abstract
The data acquisition from the freeze-drying process is important for obtaining freeze-dried samples with the desired final moisture content under various operating conditions. The current study extensively presents a simple and low-cost methodology for implementing a data acquisition system in a laboratory-scale freeze dryer. The results showed that higher drying temperatures (40?C) increased the errors involved in measuring the mass of material; nevertheless, the application of correction blank curves statistically significantly reduced those errors. In general, the system developed provided precise and accurate measurements of the temporal changes in the sample mass and temperature, and chamber pressure variations, allowing monitoring of the production process of freeze-dried samples with low final moisture contents.
