Summary: Freeze drying, also known as lyophilization, is a vacuum-sublimation drying process for pharmaceutical products. Microwave-assisted freeze drying is an alternative method that utilizes microwave irradiation to dry the product, reducing drying time by 70%-80%. This article provides exact and approximate analytical solutions for conventional, microwave-assisted, and hybrid freeze drying, serving as reference solutions for validation and offering computationally efficient and accurate results.

Summary: The challenges in direct methane conversion to higher-value chemicals include catalyst deactivation and low single-pass conversion. In this paper, microwave irradiation was integrated with heterogeneous catalysis to enable higher methane conversion at lower temperatures. The results showed that microwave irradiation facilitated the catalysis process thermally and non-thermally, leading to improved methane conversion. Finite-element modeling was used to explain the non-thermal effects of microwave-assisted catalytic reactions.

Summary: Freeze-drying, a common process to preserve food and bioactive substances, has a long drying time and high production costs. This study investigates the effects of modulating the electromagnetic field in microwave-assisted freeze-drying (MFD) for process improvement. The simulation and experimental results show that targeted frequency modulation can enhance energy efficiency and drying homogeneity during MFD. The frequency-based control of MFD represents a promising approach for process control and intensification.

Summary: Waste in the food supply chain exacerbates world hunger, with most of it occurring in developing countries due to the lack of appropriate and affordable preservation techniques. Traditional open sun drying, though popular due to low cost, is highly energy intensive, unhygienic, and time consuming.

Summary: This paper discusses the factors affecting the microwave drying characteristics of rutile TiO2 and fits the data with nine common thin layers drying kinetic models. The results show that the drying efficiency of rutile TiO2 is positively related to microwave power, initial moisture content, and initial mass. The Modified Page model agrees well with the experimental data and provides a theoretical and scientific basis for the application of microwave drying techniques in the metallurgy and chemical industry.

Summary: Recently, microwave-assisted freeze-drying (MFD) has gained attention for its ability to significantly reduce the drying times of biopharmaceuticals compared to conventional freeze-drying (CFD). This study presents a new technical MFD setup that allows for the retrofitting of standard lyophilizers with microwave modules. Process data was collected to evaluate the speed, settings, and controllability of MFD processes, as well as the quality and stability of monoclonal antibody (mAb) formulations. The findings demonstrate that MFD can drastically shorten drying times, maintain good controllability, and produce stable lyophilizates with an elegant cake appearance.

Summary: This study investigates the drying properties of potato peels (PP) using two different processes: convection drying (CD) and microwave drying (MD). The drying kinetics were analyzed at various temperatures for CD and different powers for MD. The study also evaluated the effectiveness of these processes in terms of antioxidant contents and capacity. A total of 22 mathematical models were used to predict the drying kinetics, and the Sledz model was found to be the most suitable. The best drying rates for PP were achieved at a temperature of 120 degrees C and a power of 600 W. The energy consumption increased with higher temperature or power. MD showed shorter drying time, lower energy consumption, and better preservation of antioxidants compared to CD. The proposed microwave drying process for PP is recommended for various industries, including food processing.
