“…The HAD group exhibited significant differences (p < 0.05) compared to the other groups. The conclusion is consistent with the findings of Srivastav S et al [28] and Pratiwi et al [29], who used electrohydrodynamics with electrode distance variation to process carrots and potatoes. These findings provide substantial evidence validating the efficacy of HVCD treatment in accelerating alfalfa's drying process.…”

“…In contrast, the HVCD group displays significantly superior dryin rates to the AD group, with its required time reduced by 3.25 times at maximum leve and by 1.67 times at minimum levels. Furthermore, both the drying rate and duration o the HVCD group exhibit an approximate inverse relationship with the air-gap spacing The HAD group exhibited significant differences (p < 0.05) compared to the other group The conclusion is consistent with the findings of Srivastav S et al [28] and Pratiwi et a [29], who used electrohydrodynamics with electrode distance variation to process carro and potatoes.

The high nutritional value of alfalfa hay makes it a widely utilized component in animal feed. However, the current prevalent drying methods for forage have a significantly detrimental impact on the quality of alfalfa during the drying process. This study investigates the effects of high-voltage corona discharge (HVCD) treatment on post-cut alfalfa. Gradient experiments are conducted by adjusting the air-gap spacing at a voltage of 25 kV. The results demonstrate that as the distance decreases, there is an observed increase in the drying rate, rehydration rate, and color intensity of the HVCD-treated material. HVCD treatment significantly enhances crude protein content, which increases with decreasing air-gap spacing. Meanwhile, it negatively affects lignin, neutral detergent fiber (NDF), and acid detergent fiber (ADF) levels. The relative forage quality (RFQ) of alfalfa reaches its peak at an air-gap spacing of 7 cm. The application of HVCD disrupts the fiber structure and induces significant electroporation effects in cells. Minimal changes in functional groups preserve nutrient integrity. Furthermore, HVCD exhibits lower energy consumption compared to hot air dryers. The HVCD treatment is a highly efficient and effective method, with a gradual improvement in alfalfa hay quality as the air-gap distance decreases.
