| Abstract | The objective of this research was to apply micro- and nanometer-scale bubble technology, or micro-nano bubble (MNBs), for cleaning dairy milking equipment. A micro-nano bubble generator was designed and constructed, and its cleaning efficiency was evaluated by measuring microbial residues on four surfaces of the milking equipment: the milk bucket, the inner surface of the milking liner at depths of 1 cm and 10 cm, and the milk tube, over a period of three months. Additionally, the hardness of the milking liners was examined before and after use. In the first experiment, the optimal cleaning duration using micro-nano bubbles with water (MNBs-W) was determined. The milking equipment was randomly assigned into four groups according to cleaning times of 0, 5, 10, and 20 minutes. Samples were collected from the four surfaces, with three replications. Results showed that cleaning with MNBs significantly reduced the number of microorganisms on the surface of milking equipment at 5 minutes (3.64 Log10 CFU/swab), 10 minutes (3.61 Log10 CFU/swab), and 20 minutes (3.73 Log10 CFU/swab), compared with the control group at 0 minutes (4.69 Log10 CFU/swab) (P<0.05). However, no significant differences were observed among the 5-, 10-, and 20-minute treatments (P>0.05). Therefore, a 5-minute cleaning duration was selected for further evaluation in a dairy farm. Subsequently, the cleaning efficiency of the milking equipment was tested in a dairy farm. The equipment was randomly assigned according to a completely randomized design into two groups, with three milking sets per group: Group 1) cleaned using the farmers’ conventional method (Conventional), and Group 2) cleaned with micro-nano bubbles combined with water for 5 minutes (MNBs-W). The cleaning tests were conducted daily for a continuous period of three months (January–March). Results indicated no significant difference in microbial counts between the two groups (P>0.05). However, after three months of use, the milking liners in the MNBs-W group exhibited significantly lower hardness in the middle and barrel end compared to the conventional cleaning method (P<0.05). The findings demonstrate that applying micro-nano bubble technology with water for cleaning milking equipment is as effective as the conventional method involving brushing and chlorine soaking in reducing microbial contamination. Moreover, MNBs cleaning offers an alternative approach that avoids detergents and chlorine solutions, while also reducing the hardness of milking liners. |
