Processes that occur during sun drying

Exposing agricultural products to wind and sun is a centuries-old preservation method used all over the world. Cereals, legumes, and green forages are dried in the field as soon as they are harvested. Fruits, vegetables, spices, and seafood, as well as threshed grains, are laid out in thin layers on the ground or trays. Other methods include hanging the crop beneath a shelter, on trees, or on field racks.

To gain a better understanding of the processes involved in solar drying, the sun drying process is described first.

Heat is transferred to the crop by convection from the surrounding air and absorption of direct and diffuse radiation on the crop’s surface during sun drying. The converted heat is partly conducted to the crop’s interior, raising its temperature, and partly used to effect water and vapour migration from the interior to the surface. The remaining energy is used to evaporate water at the surface or is lost to the atmosphere via convection and radiation. Natural convection, aided by wind forces, must remove evaporated water from the crop’s surroundings.

These processes continue under ambient conditions until the vapour pressure of the moisture held in the product equals the vapour pressure of the atmosphere. As a result, the rate of moisture desorption from the product to the environment and absorption from the environment are in equilibrium, and the crop moisture content at this point is referred to as the equilibrium moisture content. The drying process is slow under ambient conditions, and the equilibrium moisture content is insufficiently low for safe storage in environments with high relative humidity.

Due to the hygroscopic properties of all agricultural products, the crop can be dried or rewetted during sun drying. Remoistening effects can occur either by condensation of dew or by vapour diffusion caused by osmotic or capillary forces, especially at night when the ambient temperature decreases in general, causing a simultaneous increase in humidity.

As previously stated, this drying method has numerous drawbacks. Solar drying is a technical alternative to the traditional method of sun drying.

The processes that happen during solar drying

The goal of a dryer is to provide the product with more heat than is available under normal conditions. This increases the vapour pressure of the moisture in the crop and significantly reduces the relative humidity of the drying air, which increases its moisture carrying capacity and ensures that the equilibrium moisture content is low enough.

Dryers that use the sun You can use these principles to make other products and designs, because they all need to remove water. It was made for rice, but they can also be used to make other products and designs.

Convection: The natural flow of air in a dryer moves the air. As it moves through the collector, it gets heated up and then cools down a little as it takes in moisture from the rice. Both the air and the sun are used to warm up the rice.

Warm air can hold more moisture than cold air, so the amount needed is based on the temperature of the collector and the amount of moisture it had when it came into the collector.
The goal of most drying processes is to get the moisture content of the product down to a certain level so that it can be used. Moisture content is a way to say how much water makes up a given amount of weight (wet basis)

When water evaporates, 2.26 kJ/kg of heat must be used to do it. As a result, it takes about 250 MJ (70 kWh) of energy to evaporate 100 kg of water. There is no set amount of solar heat that the dryer needs. This is because the air that comes in can use some of its own energy to evaporate the water (becoming colder in the process). Indeed, if the air around you is dry enough, no heat is needed.

However, extra heat is good for two reasons. The air needs less of it if it’s warmer. Second, the temperature of the rice grains may be important, especially in the later stages of drying when moisture must be “pulled” from the center of the grains to the outside of the grains. This temperature will be based mostly on the air temperature, but also on how much direct sunlight the product gets.

Many different types of solar dryers have been made to cut down on post-harvest losses and improve the quality of the products they make.

Solar Dryer Tent to Support Farmers in Africa

Agriculture is the most important part of the economy in the majority of African countries. Agriculture employs 80-90 percent of the working population. Despite these large numbers, national food production still falls short of meeting the population’s needs. The lack of appropriate preservation and storage systems resulted in significant losses, resulting in a significant reduction in food supply.
Food conservation, such as drying, can smooth out the dent in food production caused by crop failures as well as significant seasonal fluctuations in availability.

Because solar irradiance is very high for most of the year, sun drying of crops is the most common method of food preservation in many African countries. There are some disadvantages to the traditional method of drying, which involves spreading the crop in thin layers on mats, trays, or paved grounds and exposing it to the sun and wind.

Poorer food quality is caused by dust contamination, insect attack, enzymatic reactions, and microorganism infection.

This system is also labor- and time-intensive, as crops must be covered at night and during bad weather, and crops must be constantly protected from domestic animal attack.

Non-uniform and insufficient drying also contributes to crop deterioration during storage. Serious drying issues arise, particularly in humid tropical regions where some crops must be dried during the rainy season.

To ensure a continuous food supply for the growing population and to enable farmers to produce high-quality marketable products, efficient and cost-effective drying methods are required. According to studies, even the smallest and most basic oil-fired batch dryers are unsuitable for most farmers due to a lack of capital and an insufficient supply of energy for the dryers’ operation

High temperature dryers used in developed countries are only economically viable on large plantations or large commercial establishments in developing countries. As a result, the introduction of low-cost, locally manufactured solar dryers represents a promising alternative to reducing the enormous post-harvest losses. The opportunity to produce high-quality marketable products appears to be an opportunity for farmers to improve their economic situation. However, given the low income of developing-country rural populations, the relatively high initial investment for solar dryers remains a barrier to widespread adoption.

Solar Tent Fish Dryer

Solar tent fish dryer is a new and innovative way of drying the fish. It is a solar powered dryer that can dry fish without applying any heat. Fish are dried in a closed environment and the water evaporates from the surface of the fish. The water vapor condenses on the inside lining of the tent, runs down to a collector at bottom, and then drips out of an outlet pipe to a container for collection.

This type of dryer is more energy efficient than other types because it does not require any power to run, which means it can be used anywhere in the world without worrying about electricity or fuel sources.

Design and Fabrication of Solar Dryers for Sustainable Livelihood of fishermen.

The design and fabrication of solar dryer is a sustainable solution for the livelihood of fishermen. This project is developed in partnership with the Coastal Community Network (CCN) and the Fisheries Development Project (FDP) in order to help fishermen to have a better way of drying their catch.

The design and fabrication of solar dryer will be an effective tool that can help fishermen to save their time, effort, and money. The fishermen will no longer need to use firewood or charcoal as fuel for drying their catch. They can also save fuel by using this solar dryer which will reduce pollution in coastal communities.

Recent Advances in Solar Drying of Agricultural Products.

Solar drying is one of the most promising technologies for sustainable food processing and preservation. It has been used for centuries to dry agricultural products, such as grains, fruits, and vegetables. Solar drying has many advantages over other drying methods, such as high energy efficiency, low environmental pollution and a long-term investment.

The use of solar dryers is becoming increasingly popular in both developing and developed countries due to their benefits. They are also more cost-effective than other traditional methods because they can be built with locally available materials at low cost.

Evaluating Economic Viability of Large Fish Solar Tent Dryers

Large fish solar tent dryers are a great way to dry fish in developing countries. Solar power is abundant and it is a sustainable energy source. This can help reduce the cost of running the dryer and make it more affordable for small-scale farmers.

Solar tent dryers lead to gender equality in the fish value chain.

Sudanese women are able to work in the fish industry because of solar tent dryers. A woman in Sudan can dry up to 100 kilos of fish a day and earn more than $500 per month.

Solar tent dryers are a great advancement for women as they provide them with an opportunity to work in the fish industry. This is important because it is one of the few industries that employs many women, and there are not many opportunities for them in Sudan. The solar tent dryers have led to a gender equality in the fish value chain, where men and women have equal chances at working.

A solar tent dryer is a type of dryer that uses the sun's energy to dry fish. It is similar to other drying equipment, but differs in that it has a separate solar collector and drying chamber. It was originally designed to dry paddy, but has also been used to dry fish.

The solar tent dries fish at a much faster rate than traditional drying methods. This results in cleaner, better-tasting fish that have a longer shelf-life. Traditionally, four out of ten fish caught during harvesting season will spoil before they're worth anything. With a solar tent, the fish are cleaner and have a longer shelf-life. The open-air drying process exposes fish to dust, house flies, and other contaminants.

Both methods of drying have their advantages and disadvantages. In fact, both techniques have their benefits and drawbacks. Sun-drying is more economical, but it results in a product that has lower nutritional value and lower flavor than its solar-dried counterparts. Furthermore, it produces a lower moisture content and can result in unacceptable colour changes.

Solar-drying is an economical method that can protect agricultural products. However, it often results in a lower quality product with unacceptably high levels of toxins and vitamins. It also has the potential to change colour if the crop is exposed to too much sunlight.

This process preserves the fish by removing moisture from it. The salt prevents bacteria from growing on the surface of the fish which would spoil it.

The drying of fish method has been used for centuries because it enables people to store food for long periods without refrigeration or freezing.

A solar tunnel dryer is a device that uses the solar energy of the sun to dry foods. The process is simple and requires no external energy, but the internal temperature can be quite high. To avoid any problems with temperature, a tunnel dryer should be positioned on level ground.

The solar tunnel dryer works by converting heat from the sun into heat. The process works by increasing the temperature of the air that circulates through the tunnel.

Some other drawbacks of solar drying include the high maintenance and operation costs. Despite these benefits, it is not feasible to use this method for all purposes. In addition, it is not suitable for drying materials that contain a lot of water. The heat generated by a solar dryer will cause the material to decompose, leaving it with a slimmer, more nutrient-rich product.
