Abstract:
As the world’s population is increasing, the demand for food is also increasing. Drying techniques increase the life and quality of crop and industrial food products. It also improves the economic condition of farmers. Drying reduces the water stored within the product by evaporation. It can be done by the use of conventional energy and different methods. Sun radiation is used for open sun drying around the globe. Open sun drying has many disadvantages in comparison to other drying techniques. Solar drying is comparatively clean and effective. Solar dryers are of mainly four types: 1) direct solar dryer; 2) indirect solar dryers; 3) mixed mode solar dryer and 4) hybrid solar dryers. Because electric and heat energy demand is increasing day by day worldwide, PV/T solar dryer becomes an interesting and upcoming interest of research nowadays. In this review article basics of different kinds of solar dryers and recent advancements in hybrid PV/T dryers have been presented. Results for drying grapes, medicinal herb, tomato, and wood using PV/T solar dryer are discussed in this study. Variations of drying time, energy consumption, efficiency with different air temperatures, air flow rate and RH are discussed. The use of different solar collectors, solar air heater and heat storage materials with hybrid PV/T dryer have also been reviewed.

Abstract:
Drying via solar energy is an environmentally friendly and inexpensive process. For controlled and bulk level drying, a greenhouse solar dryer is the most suitable controlled level solar dryer. The efficiency of a solar greenhouse dryer can be increased by using thermal storage. The agricultural products dried in greenhouses are reported to be of a higher quality than those dried in the sun because they are shielded from dust, rain, insects, birds, and animals. The heat storage-based greenhouse was found to be superior for drying of all types of crops in comparison to a normal greenhouse dryer, as it provides constant heat throughout the drying process. Hence, this can be used in rural areas by farmers and small-scale industrialists, and with minor modifications, it can be used anywhere in the world. This article provides a comprehensive analysis of the development of solar greenhouse dryers for drying various agricultural products, including their design, thermal modelling methods, cost, energy, and environmental implications. Furthermore, the choice and application of solar photovoltaic panels and thermal energy storage units in the solar greenhouse dryers are examined in detail, with a view to achieving continuous and grid-independent drying. The energy requirements of various greenhouse dryer configurations/shapes are compared. Thermodynamic and thermal modelling research that reported on the performance prediction of solar greenhouse dryers, and drying kinetics studies on various agricultural products, has been compiled in this study.

Abstract:
This paper aimed to design an autonomous indirect solar dryer, which can dehydrate the aguaymanto in a costeffective manner, yielding a quality product suitable for export from the central part highland of Peru. To complete this task, it was proposed to design a prototype of autonomous solar dryer of 100 kg per batch of aguaymanto, equipped with flat reflectors and forced air feed, and powered with photovoltaic energy. This system allows to dry aguaymanto fruit at the requirements needed for its exportation. The fryer has the following dimensions: inner dimensions of the drying chamber: bottom 0.60 m, width 1.40 m, and height 1.10 m, with additional 0.05 m for insulation. Hence, the outer measures are bottom 0.70 m, width 1.50 m, and height 1.20 m. Two solar collectors are proposed with the dimensions of each: 1.50 m wide, 2.40 m long, and 0.15 m height; 2 flat mirror reflectors are required. A 80 Wp photovoltaic panel was selected for the forced air system and process control. This solar dryer is expected to cope with the problem of post-harvest deterioration. Also, it will facilitate the export by improving product quality and providing a cost-effective technology.

Abstract:
The photovoltaic (pv) forced convection solar dryer comprises the solar collector, dryer and pv assemblies. It is designed for a continuous operation throughout the day. The direct solar irradiation is utilized during sunshine hours and it automatically switches power supply to the battery during cloud covers and non-insolation periods. The inclusion of a heat reservoir enables heat transfer to continue during this period. In this study, thermal and dryer analyses were done. Experimental investigations were carried out to evaluate the performance of the system by drying plantain chips. The useful power collected was found to be, 391.50W, collector efficiency, 65.6%, dryer efficiency, 39.6%, average drying rate during insolation, 0.0169kg/hr and total drying time was 23 hours. The maximum temperature attained was 55oC. The average drying non insolation period was 0.0112kg/hr. The capital cost is less than $350.

Abstract:
A solar dryer hybrid photovoltaic thermal (PV/T) system has been designed, built and its performance has been studied. This research aims to develop a stand-alone solar dyer system, portable and less maintenance. This system consists of three main parts; PV/T system with configuration-Z thermal absorber plate, multi-direction solar collector with cross absorber plate and drying chamber. Solar thermal collector which was designed in the system is called a multi-direction solar collector because the solar radiation does not get the heat through the upper part but also on the lower sides. This situation will then increase the amount of heat that will absorb by the absorber plate. The cross absorber plate will be used in a multi-direction solar collector because it can be assembled row by row. Six sets of cross absorber plates are used in this system. PV/T airflow uses configuration-Z absorber plate which is placed under the photovoltaic (PV) module. The amount of heat produced from the PV/T configuration-Z is used as the pre-heat before the hot air flows to the multi-direction solar collector. While electric energy from PV is used to operate the ventilation fan. The solar dryer hybrid PV/T system tested its effectiveness in the field under the daily solar radiation. The total efficiency generated from PV/T configuration-Z system is in the range of 35% to 52%. For the multi-direction solar collector system, the output range was generated between 32.0 °C to 46.6 °C, whereas the thermal efficiency is in the range of 50% to 70%.

Abstract:
Solar drying is one of the most vastly used technologies in rural areas, especially in developing countries, allowing for self provision and commercialization of products with an added value. Among the technical problems encountered, is the control of the operating conditions, due mainly to the intermittency of solar radiation which in turn produces a non homogeneous treatment of the product making it necessary to control both temperature and air velocity. Considering these facts, the design of a dryer for the treatment of grains is proposed, with the intention of obtaining control on the kinetics of drying using direct or indirect solar heating and electrical energy storage from a solar photovoltaic system within established air velocities and temperatures ranges. The energy required for the grain treatment is provided by a solar thermal-photovoltaic multipurpose solar unit installed in the solar testing platform at CIE-UNAM. Solar heating can be carried out by indirect heating of air using a thermo hydronic system with a water to air heat exchanger or by means of an one pass solar air heater. The heating of air can be direct during the day or using thermal storage both at night as well as the following day. The dryer can be operated during the day or the night or 24 hours a day if it is required, depending on the thermal and photovoltaic system configurations. The photovoltaic system is composed of photovoltaic panels, batteries and a charge controller and it has been designed to operate the fan motor as well as the lamps in the night time, however a total solar operation is possible by activating circulation pumps between the solar array and the dryer, between the solar collectors field and the thermal storage tank and between the storage tank and the dryer. Part of the electricity generated is for day use for the fan and the other electric components and the rest is stored for night utilization. This paper presents the conditions and parameters for the design of the grain dryer, the different heating circuits and the integration aspects of measurement and control devices of the multipurpose solar unit, as well as the operating modes.
