“…The FUM used was manually harvested from Tieli City, Heilongjiang Province, China. After harvesting, the FUM was mixed with soil, transported to the laboratory using a specialized truck, and stored in a freezer at a temperature of 2-6 C and a humidity of approximately 13%-14% to prevent water loss (Song et al, 2023).…”

“…Due to the relationship between the absorbed energy and the collision height of FUM, the collision-absorbed energy factor can be replaced by the collision height. According to theoretical analysis, the maximum collision height of FUM in the drum is 1500 mm (Song et al, 2023), and the critical height for FUM damage is 300 mm (Li et al, 2021); therefore, the value range of collision height for this study was set to 300-1500 mm. According to the principle of equal levels, the five collision heights were 300, 600, 900, 1200, and 1500 mm.…”

“…Efficient production also requires efficient harvesting techniques and the drum screening process is an essential part of harvesting (Song et al, 2023). The collisions between FUM bulbs that occur during the drum screening process are highly complex interactions owing to the collisions between large and small FUM bulbs in addition to collisions between bulbs in different positions and directions.…”

During the drum screening of Fritillaria ussuriensis Maxim (FUM), collisions between FUM bulbs are the main cause of mechanical damage. The effects of the mass relationship and the position, direction, and height of the collision on the absorbed energy and mass–loss ratio of FUM were analyzed through collision tests. The results of the constructed regression models showed that the collision direction has no significant effect on the mass–loss ratio, whereas the mass relationship and the position, direction, and height of the collision showed significance. Under different mass relationships, the collision positions and direction, and the collision height are positively correlated with the absorbed energy and mass–loss ratio, and the absorbed energy is also positively correlated with the mass–loss ratio. In addition, the influence of the mass relationship and collision height, position, and direction on the absorbed energy are highly significant. The research findings serve as a valuable reference for designing and developing low‐loss drum screening processes.Practical applicationsFritillaria ussuriensis Maxim (FUM) is a traditional Chinese medicine. The planting area is wide and the economic benefit is high. The annual economic benefit for farmers is about 1.8 billion yuan. However, the existing production method has a low degree of mechanization, especially the harvest stage, which mainly relies on manual harvesting, is limited by the number of labor force and the harvest time is in the rainy season (FUM is easily spoiled in water), which is easy to cause economic losses. To determine better working parameters, the damage factors of FUM during screening were analyzed by developing and testing the drum‐type FUM harvester. It is helpful to improve the production efficiency of FUM, and reduce the labor demand and the damage of screening to FUM.
