The Cabinet-type ERK solar dryer is manufactured by a temperature distribution process so that the inside appliance well distributed. cabinet-type comprises several components to maintain water content, including drying oven, air blower, heat-resistant pipe, hot pump, thermostat, heat exchanger, and heater. These tools are used convert radiation into conduction or convection dried agricultural ...

The objective of this work was to determine the effects of blanching and two drying methods, open-sun drying and natural convection solar drying, on the quality characteristics of red pepper. A 2 × 3 factorial design with experimental factors as 2 drying methods (open-sun drying and use of solar dryer) and 3 levels of pepper blanching (unblanched, blanched in plain water, and blanched in 2% NaC...

Since ancient times, conventional techniques of food drying, such as sun have been used. Currently, drying methods developed with the latest technology to reduce damages caused by biochemical changes, which decrease nutritional value during process. Some typical used for products are solar tunnel dryer, cabinet-type etc. While this is going on, cutting-edge being created combine several produce...

drying is a high energy consuming process. solar drying is one of the most popular methods for dehydration of agricultural products. in the present study, the performance of a forced convection solar dryer equipped with recycling air system and desiccant chamber was investigated. the solar dryer is comprised of solar collector, drying chamber, silica jell desiccant chamber, air ducts, fan and m...

Series production of R134a compressors started in 1990. 200 compressors, from the very first series, were built into cabinets placed in an apartment house in Denmark. Cabinets with R12 compressors were placed in the same apartment house as well. The cabinets have two separate cooling systems; one for a cold cabinet and one for a freezer. 10 running cabinets were called back for analysis; 7 cabi...

A domestic solar dryer with transparent external surfaces was designed, built and tested. Thin-layer drying models that describe the drying phenomena in a unified way, regardless of the controlling mechanism; have been used to estimate the drying period for several products. Temperature of the drying medium is one of the factors that affect the drying rate constant of the exponential model. Thi...
