هندسة الأغذية بالطاقة الشمسية و دورها في التنمية الزراعية المستدامة في الجزائر : المجففات الشمسية أنموذجا

الملخص EN

In our research, we tried to address the problem of the sustainable agricultural development process and its relation to food security in Algeria and the seriousness of the policies allocated in this direction, While attempting to link the sustainable agricultural development process with the modern uses of renewable energy such as food engineering through the use of solar energy dryers.

A number of results have been reached, including: • Weak policies regarding self-sufficiency in agricultural and agricultural products, where a large proportion of foreign exchange earnings are directed to cover food imports, while national production is damaged and surplus is thrown into good production seasons.

• Algeria enjoys a distinct geographical location to achieve advantage of solar energy with the vastness of areas that receive sunshine throughout the year and high radiation rates, especially in the Algerian desert sprawling.

With an abundance of areas that receive the sun throughout the year with high rates, especially in the Algerian desert sprawling.

• Weak utilization of renewable energies due to excessive dependence on fossil energies such as oil and natural gas, which contributed to the erosion of their stocks due to excessive domestic consumption due to support for oil derivatives.

• Lack of interest in the dissemination of modern solutions to reduce waste of food, such as the use of solar dryers in the conservation of surplus in the harvest seasons And re-sell or export it when increasing the demand for them, resulting in the return of farmers, and a difficult currency for the state.
