“…Air that has been heated by the solar is forced through the drying chamber by air pressure, buoyancy forces, or a combination of both. Moist air is evacuated through a chimney or an exit at the top of the dryer [38], [39]. These dryers can be used to preserve fish, vegetables, and fruits at home by drying modest quantities of agricultural items at temperatures between 40°C and 50°C.…”

Efficient drying methods and post-harvest processes are crucial to reduce waste in fruits, vegetables, and agricultural products. Factors like moisture-related deterioration, climate change, mishandling, delayed shipping, improper storage, and sales delays contribute to post-harvest losses and quality degradation. Solar dryers, especially indirect-type solar dryers, provide a practical and environmentally friendly way to preserve these goods. In comparison to other types of solar dryers, indirect-type dryers have a number of advantages. This review focuses on evaluating the performance of different configurations of Indirect-type solar dryers in terms of drying time, maximum air temperature, drying efficiency for collectors, and overall dryer efficiency. The influence of various operating conditions on the thermal efficiency of Indirect-type solar dryers is also investigated. The study provides detailed information on the sensible and latent storage units and materials used in Indirect-type solar dryers, including those operating through natural or forced convection. The review also explores the utilization of advanced technologies, such as desiccant systems, recycling processes, the use of Nano fluids and nanoparticles, and thermal energy storage, to enhance the thermal performance of solar dryers. Additionally, the paper examines potential difficulties and suggestions for selecting, using, and testing thermal storage for indirect-type solar dryers. In summary, this review provides a comprehensive examination of indirect-type solar dryers, and their performance. It highlights the potential for improving drying efficiency through the integration of advanced technologies and thermal energy storage.

In order to meet the growing agricultural demands, modern machinery needs to be deployed and cheaper energy supply needs to be ensured. With advancements in artificial intelligence, fruit harvesting robots can improve both the quality and productivity of fruit picking and increase orange fruit exports. However, to ensure effective working of the fruit harvesting robot, an energy source that is both efficient and cost-effective is necessary. This paper aims at designing of a solar energy system for a lightweight fruit harvesting robot for orange orchards in Pakistan and conducting a feasibility study for the deployment of the robot for remote agricultural land. The site for fruit harvesting robot employment is decided by irradiance using random forest regression. Solar system sizing is done based on the design and energy requirements of the fruit harvesting robot. The Homer Pro software is used for simulation of the system to analyse the potential of using solar system for fruit harvesting robot in Sargodha, Pakistan. The results show that compared to hybrid system, a stand-alone system is a more cost effective, reliable, and efficient option with a payback time of 3.36 years and levelized cost of energy being $0.085 per unit kWh. This study proves that solar energy is a viable and cheaper solution for using modern agricultural machineries, like fruit harvesting robot, in remote areas in developing countries, like Pakistan, to enhance productivity and improving quality of the produce.

Coffee pulpers generally use combustion and electric engines in operation, which have many disadvantages such as expensive fuel, pollution, and limited usage in places where electricity is supplied by the government. Therefore, a wet pulper coffee powered by an alternating current electric engine based on solar panels was developed. This study aims to produce and test a solar-powered alternating current electric engine wet pulper for coffee. This research went through several stages which are collecting secondary data, designing the tools to be developed, technical analysis, and performance test. The development of the pulper machine included an electric motor with a power of 1103.64 W, with a maximum machine rotational speed of 1400 rpm, an inverter, a 12 V and 100 A battery, a solar panel, and a 24 A solar charge controller. The performance results showed a stripping capacity of 783.176 kg∙h−1 and the best percentage of stripped coffee pulp at a machine rotational speed of 467 rpm and a mass of 3 kg. The findings show that a pulper powered by a solar-based alternating current electric engine can be a viable solution for areas without electricity and a suitable replacement for combustion engines.
