Recent developments in drying processes and technologies have led to significant improvements in energy efficiency, environmental sustainability, and product integrity. This Special Issue focuses on cutting-edge advancements in drying methods, such as novel hybrid technologies, energy-efficient systems, and the optimization of drying parameters for different food materials.

The Special Issue will feature contributions that explore drying kinetics, the influence of drying on food nutritional and sensory attributes, industrial-scale applications, and the integration of drying with other food processing operations. The goal is to promote knowledge exchange and provide comprehensive insights into future directions of drying technologies in the food industry.

The aim of this Special Issue is to showcase the latest innovations and advancements in drying processes and technologies that play a pivotal role in modern food processing. Drying is a key unit operation in preserving food products, enhancing shelf life, and maintaining nutritional and sensory qualities. This Special Issue invites original research, reviews, and case studies focused on novel methods, optimization techniques, and energy-efficient approaches to drying technologies in food processing.

The scope covers a wide range of topics, including, but not limited to, the following:

  • Drying kinetics and modelling in various food materials;
  • Novel and hybrid drying technologies (e.g., freeze-drying, microwave drying, vacuum drying, infrared drying);
  • Energy-efficient and eco-friendly drying systems;

A three-stage research using distilled water and maltodextrin as model feed solutions was conducted to study the influence of inlet air humidity on spray drying performance. In the first and second stage, spray drying of distilled water and 30% (solids, w/w) MD solutions were tested at variable feed rate (0.16–0.83 mL/s), inlet air humidity (0.1–0.3, 1.1–1.3, 9–10 g/m3) and inlet air temperature (80–120 °C). In the third stage, the optimization of MD solutions spray drying process variables (80–120 °C inlet air temperature, 0.1–0.3, 1.1–1.3, 9–10 g/m3 inlet air humidity, 10–30% feed solution concentration) were verified for maximum powder recovery and powders of low moisture content and activity. It was noted that inlet air humidity influenced the spray drying performance. Reduced humidity improved the process conditions, but the most satisfying powder properties were noted at 120 °C, thus decreasing inlet air temperature was not necessary to ameliorate the process performance. Optimization in the third stage of the study enabled us to estimate the most satisfying properties of maltodextrin powders. The highest powder recovery and the lowest moisture content and water activity were optimal for spray drying at inlet air temperature of 120 °C, inlet air humidity of 0.1 g/m3, and feed solution concentration of 29.571%.

This study explores the combined use of convective and infrared drying (CIRD) for bread slices, utilizing advanced MEMS sensors to monitor temperature, moisture, and drying rates in real time, optimizing efficiency, and energy use. The dehydration kinetics of 1 cm thick bread slices under a controlled CIRD method was used. This analyzes drying rate (water loss speed, WLS) and energy efficiency (EE) using sensor technology. IR drying used 150 W lamps at 7 cm and 15 cm, while convective drying involved 60 °C hot air at 3 m/s. Sensor data aligned with gravimetric measurements. The most energy-efficient model used a 150 W IR lamp at 7 cm (0.645 kWh, 21.572 kWh/kg water removed) but had the longest drying time (220 min at 15 cm). The least efficient model used a 250 W IR lamp at 15 cm (EE = 32.734 kWh/kg). These results of CIRD in bread drying are statistically significant and can be applied to industrial bakery drying processes, helping manufacturers to reduce energy costs, and adopt sensor-driven process control for enhanced sustainability. The CIRD model, which uses a 150 W IR lamp placed 15 cm above the bread slices being dried, represents the most effective optimization strategy. Full article
