The drying of straw crop resources can impede the growth and reproduction of microorganisms,achieve the goal of long-term preservation,and after drying treatment,the weight and volume decrease.It not only saves storage space and transportation costs,but also improves the economic benefits of agricultural products.Traditional drying techniques have problems such as long drying cycles,poor quality,and high energy consumption.Solar-assisted heat pump drying,as a new drying method,has been prac-tically applied in the field of agricultural product drying.It is evident that the solar assisted heat pump drying technology has the po-tential for further improvement in terms of system energy efficiency,stability and reliability enhancement,and intelligence level im-provement.This article discussed the development and application of solar-assisted heat pump drying technology in the field of agri-cultural drying,and pointed out three ways to improve the performance of solar-heat pump systems,i.e.,improving photovoltaic thermal energy system,optimizing solar collectors,and developing multi-heat source heat pump system.This article analyzed the current research state on the application of solar-assisted heat pump drying technology in straw materials,including the drying perfor-mance,control systems,and prediction models of these systems.It also discussed future research directions and development priori-ties of solar heat pump systems,and explored the potential of drying schemes with waste heat secondary recovery to enhance their ap-plication in the field of agricultural drying.
