First, you have to decide what drinks to pack and how many bottles you want to pack a day. The price of machines with different output varies greatly. Judging from your investment budget, it is estimated that your output will not be great. I suggest you buy a semi-automatic bottle washer and an automatic stand-alone filling machine and capping machine. All three sets can be completed in less than 10W. Continuous spray sterilizer is the best high-temperature sterilization machine, but the price will exceed your budget. Generally speaking, it costs hundreds of thousands. Therefore, it is suggested that you put it in boiling water for more than ten minutes after screwing on the lid, and the same sterilization effect can be achieved.
