What is a Water Filling Machine and How it Work?

Classification and Characteristics of Bottle Rinsing Machines

Bottle Rinsing Machine: The clean water is distributed to the bottle washing area through the water distribution plate, and the rinsing nozzle are evenly distributed in the bottle washing area to ensure a uniform water supply in each station.

Rising Nozzle: Single rinsing media and double rinsing media (aseptic line)

Rinsing Machine in 3 in 1 monoblock: Product water rinsing

Bottle Mouth Rinsing: All adopt flip bottle clamp

1) Fixed nozzles (this is generally used)

2) In-depth bottle mouth flushing-1L, 1.5L large bottles, bottles with high cleaning requirements, for bottles that have been transported over a long distance.

Bottle clamp and overturning mechanism sliding sleeve, using German IGUS corrosion-resistant and maintenance-free bearing.

It is equipped with bottle rinsing water recovery tanks and recovery pumps to minimize water consumption. (Most of the water is direct discharge, you can also add a filter to recycle bottle rinsing water, and the beverage line is often recycled to cooling tunnel)

The rinsing time is 4 seconds and the draining time is 2 seconds.

Rinsing angle: about 120°.

Bottle rinsing machine:

Rising classification (flushing medium).

1. Disinfectant and sterile water.

2. Sterile water

18-18-6 water bottling machine works

Working principle of filling machine:

Filling machine is generally divided into linear filling machine and rotary filling machine, now our company mainly produces rotary filling machine. The work flow of the whole filling machine (take the three-in-one water filling monoblock as an example, four-in-one and five-in-one will increase the bottle rinsing station): the bottle in the air conveyor is transmitted by the bottle clip type or star wheel type rinsin machine of the three-in-one filling machine.

The rotary disc of the bottle punching machine is equipped with a clamped bottle mouth type stainless steel bottle clamp, which holds the bottleneck and flips 180 °along a guide rail to make the bottle mouth downward. In the specific area of the bottle rinsing machine, special nozzles spray rinsing water to clean the inner wall of the bottle and the outer wall of the bottle at the same time. After the bottle is washed and drained, the bottle is clamped and turned 180 °along the guide rail to make the mouth of the bottle upward. The washed bottle is exported by the bottle rinsing machine and transferred to the filling machine through the bottle clip type or star wheel type transition pulley. The bottle entering the filling machine is held by the clamp on the lifting cylinder and rises and falls under the action of the cam. The filling machine adopts gravity filling mode, the bottle mouth rises and opens the filling valve to begin the filling, and the filling ends when the material rises to the position of blocking the return hole. After filling, the bottle mouth drops away from the filling valve, and the bottle enters the capping machine through the bottle clip type or star wheel transition pulley. The stop knife on the capping machine gets stuck at the bottleneck to keep the bottle upright and prevent rotation. The capping head rotates and rotates on the capping machine, and the capping, capping, capping and uncapping actions are realized under the action of the cam, and the whole capping process is completed. The finished bottle is transferred from the capping machine to the bottle conveying chain through the bottle plucking wheel, and the three-in-one filling machine is transmitted by the conveying chain.

There are liquid level floating balls in the annular tank to control high and low liquid levels. Our filling valve is the fastest in China, up to 200ml.

After the new valve is fitted with a fake cup, it can be completely closed and can be cleaned by CIP, either forward or backwash.

According to the filling principle, the filling machine is mainly divided into:

1. Gravity filling.

2. Isobaric filling.

3. Negative pressure filling.

4. Flowmeter filling.

5. Weighing filling

Gravity filling is mainly used in drinking water production line.

Gravity filling, also known as atmospheric pressure filling, is mainly used in production lines with low viscosity, no gas or low filling precision, such as water, fruit juice, tea drinks and so on.

The main principle is that the filling valve controls the rise and fall of the bottle through mechanical transmission control (cam) or cylinder transmission, open the valve, and the liquid is poured into the bottle with gravity. When the liquid rises to the position of the return hole, the filling stops and the bottle drops away from the filling valve.

(Water line) Types and characteristics of filling valves:

Low speed water valve:

Features: slow filling speed, liquid level can not be too high, can not reach the position of the support ring.

Flow rate: about 140ML/S.

Applicable production line: 5,000-30,000BPH.

The principle of fixed liquid level: when the liquid level rises to the position of the return hole, plug the return hole to make the liquid stop filling.

The liquid level can be adjusted by controlling the thickness of the bottle mouth pad.

High speed water valve:

Features: large valve caliber, fast effluent speed, generally can only be full filled with water.

Flow rate: about 200ML/S

The principle of fixed liquid level: the material reflux pipe draws out the excess material and returns it to the raw water tank, which can also be discharged directly. The return pipe is matched with the false cup, and when the length of the return pipe is changed, the false cup needs to be replaced accordingly.

CIP cleaning: The new return pipe goes back to the outside of the liquid cylinder to ensure that the liquid cylinder is clean, and the return pipe of the old filling valve goes directly back to the liquid tank.

Types and characteristics of filling tank.

Combiblock is annular cylinders, and the cleaning period of CIP is shorter than that of the whole type.

Ordinary-integral type-high demand for water supply and stable flow.

Cip is easy to clean.

CIP– water.


Water (hot and cold water is fine).

Large equipment with circular, 36000BPH capacity.

Water line filling tanks are mainly divided into two types: integral and annular.

Integral type:

Features: independent of filling valve.

Advantages: CIP can disinfect more widely and completely without dead corner when cleaning.

Annular filling tank:

The annular filling tank is controlled by a floating ball to control the high and low liquid level, and the filling pump is fed at low level.

Filling valve flow rate: we are the fastest in China, single valve 200ml per second.

Advantages: suitable for high speed valve

Classification and characteristics of capping machines.

Magnetic torque.

Ordinary capping machine, washable capping machine, aseptic capping machine.

Ordinary: self-made.

Washable type: buy Warner swivel head only.

Aseptic: CSI, Arol

Classification and characteristics of capping head.

Pressing capping machine for bottle caps without threads.

Outsourcing brand: AROL (Italy), WARNER (USA), CSI (Germany)

Characteristics of Lubrication system of filling Machine.

Central lubrication + manual lubrication

Screw bottle inlet-more than 5L PET, glass bottle.

Block the cylinder (intercept the bottle in the air duct).

Fuel pump regular refueling-central centralized lubrication.

Cantilever touch screen-can rotate.

Our features: stainless steel platform panel through-hole tension structure, combined with O-ring sealing ring, so that all the bearing seats and supporting shafts and other easy permeability on the table may be reduced to zero.

Bottle delivery mechanism: quickly remove the guard plate of the plucking wheel and change it quickly.

Classification of empty bottle transmission structure in filling machine and their respective advantages and disadvantages.

1) clip, fragile parts, but can be replaced in a short time.

2) the pulley is sturdy, but it takes time to replace.

1. Transition nylon plucking wheel bottle body-glass bottle, heavy.

2. Steel pulley hanging bottle mouth-single bottle type, no need to replace parts, more stable.

3. Steel clip clamp bottle mouth-ordinary PET.

Types and disadvantages of empty bottle lifting in filling machine.

1) cylinder, more than 40 filling valves need to be lifted by cylinder.

2) double guide rail, for small machines, such as 32 filling valves need to use double guide rail type.

The advantages of the solid bottle transmission structure of the filling machine:

Out-of-bottle part: bottle plucking wheel-spiral drop tray (descending along the spiral curve without impact on the bottle).

Transmission classification of filling machines and their respective advantages and disadvantages.

Rely on servo motor for transmission, its advantage is that the operation is relatively stable and accurate.

Gear multi-section transmission-multiple motors-affect filling accuracy.

A motor, with universal coupling for long-distance transmission,-speed without clearance, good synchronization, high precision, more transmission stages, reducer, sudden stop has little impact on the motor.
