What It Is

AGAIS (Armazenagem de Grãos, Agroindústria e Simulação) is a Portuguese-language agricultural engineering technology website. Its purpose is to share methods, techniques, and concepts related to agro-industrial systems engineering. According to the site content, it focuses on grain drying, storage, and processing; the organization of agro-industrial system operations; and the use of operations research, modeling, and simulation in technical and economic evaluation. It is not a typical MOOC or commercial course platform, but is closer to a specialized knowledge base and collection of engineering calculation tools maintained by a university professor.

Core Content and Format

The content is divided into sections such as “Armazenagem” (storage), “Agroindústria” (agro-industry / agricultural product processing), and “Modelagem & Simulação” (modeling and simulation), covering topics including drying, aeration, storage, agricultural product processing regulations, and simulation of agro-industrial environments. The site also provides online or downloadable applications, including calculations for psychrometrics, impurity and moisture losses, equilibrium moisture content, intergranular air relative humidity, rack dryer drying simulation, aeration scenario analysis, as well as financial calculations such as capitalization, financing, and Price tables. The captured text also mentions an AgaisPsicro demo video and a lecture titled “Efficient Storage: Reducing Losses and Optimizing Operations.”

Instructor, Pricing, and Certification

The site was developed by Prof. Luís César, a professor in the Department of Agricultural Engineering at the Federal University of Viçosa in Brazil. His focus areas include agricultural product storage and processing, and he has experience in logistics, agro-industrial systems, and modeling and simulation of grain storage systems. He has also taught at UNIOESTE and UFES, and served as an instructor at CENTREINAR-UFV. The site content does not specify pricing, payment methods, certificates, or accreditation, so it should not be treated as a course product that provides formal certification.

Pros and Cons

Its main strength is its strong professional focus, especially for niche use cases such as grain storage, drying, aeration, and agro-industrial simulation. The calculation tools can also support engineering judgment and teaching demonstrations. The drawbacks are that it is not highly structured as a course: there is no clear learning path, quizzes, assignments, community, or learning support. Some page information is also repetitive, and the site is mainly in Portuguese, which creates a language barrier for Chinese learners.

Who It’s For and Access from China

It is better suited to agricultural engineering students, researchers, grain storage and processing professionals, and engineers who need to perform technical and economic calculations. Access from China cannot be determined from the available content, so it should be treated as “unknown.” If using it, users should focus on assessing their Portuguese reading ability and whether the tools fit their needs.
