SUMMARYA solar dryer fitted with a novel design of absorber having inbuilt thermal storage capabilities was designed, fabricated, simulated and also tested at Rajiv Gandhi College of Engineering Research & Technology, Chandrapur (MS) India. Thermic oil was used as a storage material. The main objective of the study was to reduce the drying period and enhance the quality of dried product mainly chillies and fenugreek leaves. The products were laid in a single layer. The dimensions of the dryer were arrived at using the well-defined procedure available in literature. The mass of thermic oil needed in the absorber and mass of product to be dried in trays were optimized using simulation techniques. The maximum drying air temperature required for drying agricultural products was around 658C: The ambient conditions at the location were 25-408C; 16-43% RH and solar radiation 105-1024 W m À2 : Experimental studies based on temperature and humidity measurements were performed on the dryer. The research concluded that the desired drying air temperature was achieved and maintained for a longer period. The length of operation of the solar air heater and the efficiency of the dryer were increased, and better quality of agricultural products in terms of colour value were obtained compared with open sun drying.

“…It is essentially a technique for preservation of food materials by reducing the activity of water to a level for enhancing length of desired self-life [2]. In several cases, the drying process is connected to some physical and chemical processes inducing proper internal biochemical and/or microbiological changes, which should take place simultaneously to ensure the characteristic quality features of the product like color, smell, taste, consistence and shape [3]. Drying is an energy intensive process and generally it is defined as the removal of moisture by the application of heat and it is practiced to maintain the quality of product during storage [4].…”

Drying or dehydration is a simple, low-cost way to preserve food that might otherwise be spoiled. Drying removes water and thus prevents fermentation or the growth of molds. In ancient times, fruits and vegetables were exposed to direct sun light for drying. However, in this method, there are several drawbacks. In the present work, a photovoltaic integrated solar dryer has been fabricated and tested for drying of fruits and vegetables. A d.c. fan powered by photovoltaic cell has been incorporated in the system to create forced air circulation in transferring thermal energy for drying without the use of grid connected power supplies. The dryer has been coupled to a solar air heater having a sun-tracking facility and blackened absorber for enhancing solar energy absorption. The system consists of a photovoltaic panel, solar air heater and a drying chamber with chimney. This system can be used for drying various agricultural products like fruits and vegetables. In this work, the experimental study has been conducted for the forced mode of drying for cabbage.

In this paper, a new design of a natural convection solar dryer used to dry fruits is presented; taking into account the local climatic conditions prevailed in Jordan during summer season. The dryer will have a capacity of 100 kg of sliced apples and the simulation is based on mass and heat balances. It is deemed that such new design will be able to reduce the original moisture content, of the final product, to 10% within two days. The special tailored program could be used to calculate drying parameters for similar products under different climatic conditions. The next step will be focused on constructing the solar dryer in order to conduct actual experiments in the field.
