The designing of appropriate equipment is of great importance for the success of technology. Therefore, it is necessary that researchers who introduce a certain technology into practice constantly bear in mind the possible engineering solutions which would be compatible. This technology comprises osmotic dehydration, as a pretreatment, and hot air convective drying. The limit criteria for selection of the technology parameters were formed based on the requirement that the product quality is preserved to a high degree. Another important quality of this technology is energy sustainability, which is based on renewable energy sources. Special attention was given to the protection of fruits and vegetables from mechanical damage. For this purpose, the system of material handling in shallow crates was designed during the process of osmotic drying and sulphurisation. Adhering to the previously mentioned principles, the following original equipment was designed and constructed: osmotic dryer, sulphuring chamber, convective dryer with racks, evaporator of osmotic solution and solar air heater.
