Conventional packing method is first with bottle rinsing, then filling. But nowadays a modern better method to meet the food sanitary requirements is to reserve the tops of the bottle necks before bottles are sent to the beverage factory. As the top necks of bottles are eliminated by the neck trimmer, then sent into the filler at once.
The advantages are no need to rinse the empty bottles to save the water and avoid cleaning liquid remains in the bottles and the problem of waste water treatment. Neck trimmer is a rotary machine. It's suitable for eliminating the top neck of HDPE bottles. The change parts are easily exchangeable for handing different bottles size and the operation is performed without using any tools.
The machine includes electric height adjustment for different size of bottles. It's very convenient to adjust the height of machine. The tops are removed through a funnel immediately after being cut off. The bottles which have not been cut are ejected by inspection system located on the exit of machine.
