Abstract: The high-quality forage is the basis of the healthy development of modern animal husbandry, which requires scientific control of planting, field management, harvesting, and processing. Drying is a key link in the post-harvest processing of forage, which significantly affects the quality of forage. To provide reference and technical support for the development of China's forage post-production processing industry, this paper summarizes the technology of forage harvesting and drying, and reviews and analyses the research advances of forage drying characteristics and drying equipment under the main drying methods in China and other countries. The main drying methods of forage grass include natural drying, hot air drying, high-temperature-fast-drying, solar drying, etc. In recent years, domestic scholars have studied the drying characteristics of forage grass under different drying methods. The domestic forage drying technology has been gradually improved, but it still lags behind the mechanized production technology of forage drying in foreign countries. There are problems of domestic forage drying technology, such as the mismatch between harvest and drying process, the lack of design standards for drying equipment, and small enterprise scale. Thus, the development direction of our country's forage mechanized drying processing industry is to formulate standardized forage drying processing technology, strengthen the research of forage drying technology, realize intelligent and integrated forage drying equipment.
