  • Department of Mechanical Engineering, Lakshmi Narain College of Technology, Bhopal − 462021, Madhya Pradesh, India


Background/Objectives: Today the greenhouse drying technology has reached at a remarkable stage due to its tremendous contribution towards saving the agricultural products from spoilage. This has helped the whole world to progress at a fast rate as they are able to save a lot of conventional energy requirements which was being wasted earlier in food. The main objective of this paper is to provide a general idea of progress that has occurred in the field of active greenhouse solar dryer time to time. Methods: This paper focuses on some historical work in the field of active greenhouse drying and recent development in this field to improve the performance in terms of temperature and quality of the agricultural products. Findings: This review paper provides detailed and systematic information of research carried out in the field of solar greenhouse drying operated under forced convection mode. Applications: This review work not only provides the general reference to the researchers working in the same field but also helps to farmers for the possible modifications in the method of drying and further improvements in future.
