This section gives a record of all the work and inquiries about what has been done concerning the drying of maize. Since this project is generally about the drying methodology of maize, diverse techniques, essential parameters in the drying process, and each and every other component’s composition that will help in the design of the sun-powered maize dryer will all be examined in this chapter. A record of what was done in the past work concerning this project is given in this chapter. The composition/writing reviews in this endeavour are basic to help the design and recreation of this project. The literature survey fused into this chapter was extracted from sites, journals, books, and articles.
2.1 Types of Drying Method
There exist various types of grain drying systems which are basically recognised by the technique for drying. the two procedures are distinguished by the controlling components of drying the grain (Kenneth and Hellevang, 2017). Drying of maize is done either by methods for artificial drying or normal drying with no outside capacity to force heated warm air through the grain to dry it. At the same time, the two unforced air-drying and artificial air-drying systems are illustrated in the coming sections 2.1.1 and 2.1.2. Figure 2.1 exhibits the structure of drying systems
