A comparative study on drying of basil leaves CIGR Journal
Parmar, Mansukhlal Ramjibhai; Kumpavat, Mahendrasinh T.; Doshi, Jayesh Sevantilal; Kapdi, Shyamsundar S..
Basil is a popular aromatic and annual herb growing in many regions of the world.  Immediately after its harvesting, the highly perishable raw material, i.e. leaves, have to be preserved against deterioration and spoilage.  More often, during peak period, most of the crop is lost/wasted due to lack of proper post-harvest processing techniques.  Drying is by far the most widely used treatment, which needs to be performed very carefully and preciously so as to preserve the aroma and color of the leaves.  Various drying treatments and experimental methods viz., solar drying, tray drying, vacuum drying and fluidized bed drying were carried out at the temperatures of45°C,55°Cand65°Cto find and suggest the optimum drying condition for acquiring quality dried...

Developing a mixed solar drier for improved postharvest handling of food grains CIGR Journal
DHANDE, HIMANSHU KISHOR; SHELARE, SAGAR DNYANESHWAR; KHOPE, PRAVIN BALKRUSHNAJI.
Drying of grain is usually achieved by spreading grains on earth for solar radiation. This technique is moderate, but being unsecured from a downpour, dust, invasion of bugs, rodents, and distinct animals, items might be severely degraded to the degree that occasionally becomes contaminated and issued loss of nourishment excellence. To defeat this, solar drying is the greatest assuring technique for the protection of agricultural commodities. In the proposed research, the low-cost mixed-mode solar dryer was developed (Workshop of Dr. D. Y. Patil Institute of Technology, Pimpri, Pune, Maharashtra, India) using locally accessible, environmentally friendly materials, and the performance was evaluated. The solar dryer was developed using the components like a...

Effectiveness of a solar grain dryer for drying paddy seed in Bangladesh CIGR Journal
Roy, Dipika; Saha, Chayan Kumer; Alam, Md. Monjurul; Alam, Md. Ashraful; Sarker, Tumpa Rani.
Proper and timely drying is needed for producing quality paddy seed. Open sun drying is often produced seed with foreign materials.  Solar dryer produced by science for society (S4S), India might be suitable for country like Bangladesh. Therefore, an attempt was taken to evaluate S4S seed dryer at the Workshop, Department of Farm Power and Machinery, Bangladesh Agricultural University, Mymensingh. In this experiment, the spatial and temporal distribution of temperature and moisture in S4S solar grain dryer was investigated and the seed quality was also evaluated. The dryer performance was evaluated with six trials in Boro season from May 10 to June 6, 2017 and with three trials in Aman season from November 7 to 11, 2017. Paddy seed samples were also dried...

Experimental study of dehydration processes of raspberries (Rubus Idaeus ) with microwave and solar drying Ciênc. Tecnol. Aliment.
RODRIGUEZ,Anabel; BRUNO,Estela; PAOLA,Carlos; CAMPAÑONE,Laura; MASCHERONI,Rodolfo H..
Abstract The aim of the present study was to evaluate the effect of solar and microwave drying on raspberries (Rubus Idaeus) cv. Heritage. The efficiency of drying was evaluated in terms of weight reduction in function of the time. The quality properties evaluated were color, texture, antioxidant capacity and total polyphenols content. The results showed that solar drying and microwave drying allowed a good preservation of surface color in the final product. However, the solar drying achieved a desirable texture in dried raspberries compared to microwave drying. Neither solar drying nor microwave drying allowed a high retention of the antioxidant capacity. Nevertheless, both processes allow obtaining final stable fruits (low water activity) at any time of...

Modeling of drying thin layer of tomato slices using solar and convective driers CIGR Journal
Khama, Réda; Aissani-Benissad, F; Alkama, R; Fraikin, L; Léonard, A.
This paper presents a mathematical modelling of thin layer drying of tomato (Solanum lycopersicum L.). To this end, two different methods are used to dehydrate tomato slices namely the solar drying (in an indirect solar dryer), and the forced convective drying (in a convective dryer). In the solar dryer, the experiments are carried out at a constant air velocity of 1 m/s and average temperatures of 37.2, 39.9, 42.5 °C. In the convective dryer, the experiments are performed with five different temperatures (30, 40, 50, 60 and 70 °C) at a constant air velocity of 1 m/s. In order to estimate and select the appropriate drying curve equation, fifteen different thin layer mathematical drying models available in the literature are applied to the experimental...
