Project Summary

A solar food dehydrator is used to dry foods, like fruits and vegetables, so that they can be stored for long periods of time. Running on solar power makes these food dryers efficient and inexpensive. Solar food dehydrators can be used in almost any climate. While people have been drying their surpluses of fruits and vegetables for centuries by hanging them out in the sun, modern solar food dryers combine these techniques with modern technology to make the most out of the sun's heat and energy. Why dehydrating foods so it is due to the reason that Taking advantage of freshly grown fruits and veggies by storing extras for use later in the year. Creating healthy snacks from fresh produce. Making fruit or vegetable leather, which is a chewy and tasty treat made from dried food. Saving money by drying and storing your own produce rather than purchasing it out of season. The working principle of the dehydrator is that Food is prepared by slicing or chopping and then placed on trays or layers of cheesecloth which are then placed inside the dehydrator. Instead of using electricity to direct warm air around the food to dry it out, a solar food dehydrator uses free, renewable energy from the sun. Depending on the design and size of your solar food dehydrator, the food inside is generally ready within two days the fruits which are appropriate for drying are apples, bananas, mangoes, strawberries, tomatoes, onions, garlic, beans, peas carrots, broccoli, pumpkin or squash, celery. The proposed project is focused on the design, construction, and performance of solar dehydrator for fruit preservation purposes. The solar dehydrator will be capable to measure humidity and inner and outer temperature. It will also be equipped with Arduino and related modules to send information to an android application, which will show all the necessary information on the user’s mobile screen. It will also be able to maintain a constant temperature inside the solar dehydrator with the help of automated doors. Battery and solar panel will include in the design to run the solar dehydrator to power up the circuit.   

Project Objectives

Following are major objectives 

• The objective of this study is to develop a solar dryer in which the grains are dried simultaneously by the heated air from the solar collector.
• This work will be based on the importance of a solar dryer which is reliable and economically design and construct a solar dryer using locally available materials and to evaluate the performance of this solar dryer
• Fabrication of solar dehydrator.
• To incorrupt smart features.
• Test.

Project Implementation Method

The Project implementation method is discussed below

• Recognition  of need
• Problem Definition
• Conceptual Design
• Geometric Model
• Engineering Analysis
• Manufacturing 
• Experimentation and testing  

Benefits of the Project

• It creates employment opportunities and sustainable profits.
• Dried products improve family nutrition because fruit and vegetables contain high quantities of vitamins, minerals and fibre.
• For diabetics dried fruit prepared without adding sugar is a healthy choice instead of desserts.
• Dried fruit can be used in stews, soups and casseroles or enjoyed as snacks. It can also be added to cereals for breakfast or used in making ice cream and baked products.
• It improves the bargaining position of farmers. Sometimes farmers sell at very low prices during the harvest season because they cannot store or preserve their surplus products.
• People are encouraged to establish their own gardens.
