Generally, solar dryer cabinets are made up of sheet metals that are heavy, costly, tend to rust over time, and possess the high heat rate to the outer atmosphere. In order to overcome these drawbacks, this research urges to develop a natural fiber reinforced polymer-based cabinet dryer, specially designed and fabricated for the purpose of solar drying. Nylon is used as the matrix material and Prosopis juliflora in particulate form is used as the natural fiber reinforcement. The dryer cabinet was designed at industrial scale to dry 5 kg of ginger at a single setting. This work also studies the efficiency of the polymer composite cabinet integrated with a flat plate solar collector system that is coated with copper and black chrome attached to corrugated fins in between the absorber plate and storage medium. The FRP chamber was compartmented in its interior with aluminium perforated sheets and experimentation was performed to determine the efficiency of the composite cabinet based on reduction of heat loss from the system. The performance of the coating, storage medium materials, and overall storage efficiency were also studied. The FRP cabinet resulted in a moisture level less than 8.5% within 4–7 days. Exergy studies showed 75% efficiency and energy studies gave 25.5 kJ/kg peak readings of drying efficiency for a period ranging between 11 and 12 hours. This was a 75% increment in energy efficiency. Thermal degradation of the FRP material was found to be stable up to 300°C. The overall weight of the constructed polymer cabinet was 25% lesser than the conventional systems.

“…The processing of fruits and vegetables at high‐temperature and long duration leads to alter the color, flavor and bioactive compounds, thus the product obtained is of reduced nutritional value (Davoodi et al., 2007). Different studies have reported the effects of drying methods, drying temperature and time on the stability of carotenoids, vitamins, antioxidants and polyphenols of fruits and vegetables (Bhanu et al., 2021; Gupta et al., 2021; Jha et al., 2015).…”

Sweet peppers (Capsicum annuum L.) are vegetable crops that possess varied aroma, color, flavor, nutritional and medicinal value (Melgar-Lalanne et al., 2017). In the last few years, sweet peppers gained the attention of researchers due to the presence of an ample amount of phytochemicals such as phenols, antioxidants, carotenoids, flavonoids, and fiber that impart neutraceutical properties. Thus, sweet pepper represents a source of beneficial compounds, which makes it a good antioxidant additive for food and increases its potential usability as a functional food (Hernández-Carrión et al., 2015). Moreover, sweet peppers have been recently reported to be effective in protecting against diabetes, cardiovascular and carcinogenic diseases because of their hypolipidemic, hypocholesterolemic, antithrombotic and anti-hypertensive effects. They also possess many other biological activities such as antimicrobial, antiasthmatic, antimutagenic, and immunomodulatory activities (Blanco-Ríos et al., 2013). Sweet peppers are strong-flavored vegetables used in a wide variety of ways, hence used as a coloring and flavoring agent in sweets, soft drinks, snacks, sauces, soups and other processed products (Giuffrida et al., 2013).However, sweet peppers are highly susceptible to microbial decay due to their high water content, therefore, need to be preserved.To enhance the shelf-life and extends the storage stability of sweet peppers various methods such as drying, evaporation, canning and freezing have been used. Drying is a widely employed method to enhance their shelf life by decreasing the moisture content which aids in microbial stability (Vincente et al., 2014). The hot-air drying is a commonly used drying technique relating to its low investment, minimum operating cost and simple process (Wang et al., 2017). Drying

Ivy gourd with a good amount of potassium (K) and calcium (Ca) offers greater benefit to human health. Studying the drying mechanism of fresh ivy gourd is very important for subsequent processes and the quality of the product. The present study is intended to perform a mineral analysis (K and Ca), ash content and color parameter (L*, a*, b*, C*, H*, and whiteness and yellowness index) of solar‐dried ivy gourd. Drying experiments are performed in a single slope solar dryer and open sun drying. During the drying process, the temperature of the dryer is maintained from 45 to 75°C, undergoing forced convection drying (air velocity of 1 m/s). Fresh and dried ivy gourd samples had high amounts of Ca (379.26–4992.24 mg/kg) and K (330.63–14690.24 mg/kg). The highest mineral values were determined in the ivy gourd samples dried inside a forced convection solar dryer. Open sun (L*43.29, a*−0.57, b*16.78, C*16.78, h*88.05), natural convection (L*41.74, a*−1.74, b*15.82, C*15.98, h*83.54) and forced convection (L*41.72, a*−2.02, b*15.81, C*15.94, h*82.72) revealed better color values in the dried ivy gourd samples. The moisture is reduced from 93.5% to 10% wet basis in the natural and forced convection solar dryer within 9 and 6 h, whereas it took 10 h under open sun drying. Forced convection solar dryer dried the ivy gourd sample in a minimal time with better mineral retention and color parameter values when compared to natural and open sun‐dried samples.
