PET Bottle Filling Machine

AGICO PET Bottle Filling Machine Introduction

PET bottle filling machine (also called hot filling machine) is a kind of 3-in-1 filling machinery, which integrates washing, filling, capping together, and is widely used for hot filling of PH<4.5 sensitive fluids such as milk, green tea, fruit and vegetable juices, and beverages in various types of PET bottles.
It is suitable for the hot filling of various juices and tea beverages and can be used for the filling of purified water and mineral water by replacing a small number of parts. The output is 5000-24000 bottles/hour, which can be selected by users. Using the advanced micro-negative pressure gravity filling principle, it fills quickly, steadily, and accurately. It is equipped with a perfect material return system, which can realize an independent gas return, not contact with materials, and reduce the probability of secondary pollution and oxidation of materials.

AGICO PET bottle-filling machine can meet the technical requirements of hot filling below 95 degrees Celsius. The filling valve and the material inlet and outlet pipelines have no sanitary dead ends and are equipped with a CIP system, and the RO water flushing device for the bottle mouth is provided before capping to ensure that there is no mold at the bottle mouth. It adopts a magnetic torque type capping head to realize the function of grabbing and capping. The whole machine adopts touchscreen control, PLC computer program control, inverter control, and other advanced technologies. PET bottle filling machine has the functions of automatic control of a capping system, automatic detection of filling temperature, high-temperature alarm of materials, low-temperature shutdown and automatic reflow, waiting for missing bottles, and stopping without caps. 

AGICO PET bottle-filling machine combines the three functions of rinsing, filling, and capping on one machine, and the whole process is automated, which is suitable for filling fruit juice drinks and fruit tea drinks in high-temperature resistant polyester bottles, and also for filling carbonated beverages such as mineral water and purified water. This machine is made of high-quality SUS304 material, the key components are precision processed by CNC machine tools, and the whole machine adopts advanced photoelectric to detect the operation status of each component.

The main performance of the AGICO PET bottle-filling machine:

  • The bottle feeding adopts an air-conveying device, which is fast and will not deform the bottle.
  • The bottle mouth flusher adopts advanced block bottleneck technology to avoid contact with the threaded mouth, which is more hygienic. The bottles are conveyed using block bottleneck technology, so there is no need to adjust the height when changing the shape of the bottle. The filling adopts a valve lifting device, and the filling valve adopts a new type of micro-pressure filling principle, which is accurate.
  • The cap sorting device is installed at a low level and fed horizontally.
  • PET bottle three-in-one filling machine integrates rinsing, filling, and capping, and is developed according to the filling process requirements of juice and other beverages. The temperature of the filled liquid is generally around 82-85 degrees Celsius.

Technical characteristics of AGICO PET bottle-filling machine:

a. Rinsing part

This machine is mainly used for rinsing new bottles of juice. The bottles are then sent to the filling machine for juice filling. 
The PET bottle enters the machine by the star wheel and the clamp clamps the bottle mouth and turns it to the bottle mouth facing down. The bottles are rinsed with sterile water, drained, automatically flipped upwards, and transported to the filler through the star wheel. 
The main structure and external protective cover of the equipment are made of high-quality stainless steel. 
Brand new stainless steel clamp, simple structure, easy to adjust. It has less contact area with the bottle mouth, which effectively avoids secondary pollution of the bottle mouth. 
The bottle rinser is equipped with a water tray to recycle the rinsing water.

b. Filling part

The filling part is to fill the material into the washed bottle sent by the bottle rinser. The filling valve adopts pressure filling, which is fast and sensitive. There is no spring in the valve, and the juice does not contact the spring, which is conducive to cleaning inside the valve.
The filling cylinder adopts a full cylinder to ensure pressure stability in the cylinder.
The whole machine has a perfect CIP cleaning interface.
The machine adopts PLC automatic control, and the fault is displayed online, such as bottle blockage, missing cap, etc. 

c. capping part

The capping part is to screw the cap onto the bottle that has been filled with juice and send it to the back process by the conveyor chain. 
The cap screwing machine drives the turntable to rotate through the reducer. Make the lid exit the hopper from the lid outlet under the action of centrifugal force. The cap is screwed by magnetic force, which has the function of overload protection, and the capping torque is stable and reliable.
