PET Packaging Know-How for Design and Performance

1. PREPARATION SYSTEM(WATER TREATMENT SYSTEM+HIGH-SHEAR SUGAR DISSOLVING KETTLE+BLENDING SYSTEM)

WATER TREATMENT SYSTEM

Applicable water source: Well water, underground water, tap water, river water, spring water, mountain water, etc.

Treated water kind: Pure water, still water, mineral water, alkaline water, etc.

Core filtration equipment: Reverse Osmosis or hollow ultrafiltration.

Electricity control system: Germany Siemens PLC

Treated the raw water into drinkable water.(Customized according to customer water quality)

HIGH-SHEAR SUGAR DISSOLVING KETTLE

In the entire batching system, the high-shear sugar dissolving tank does not operate in isolation; it is typically the starting point of the process, working in conjunction with other equipment to prepare the syrup.

 

Sugar Dissolving: Granulated sugar and hot water at approximately 80-85°C are added to the high-shear sugar dissolving tank in a ratio (e.g., 6:4) for high-speed shear dissolution for approximately 20-30 minutes to obtain crude syrup.

 

Reaction/Sterilization: The crude syrup is pumped into a reaction tank and kept at approximately 85°C for a period of time (e.g., 30 minutes) for thorough pasteurization.

 

Filtration: The sterilized syrup is passed through a filter (e.g., a dual-stage filter) to remove any activated carbon, trace impurities, or undissolved particles, resulting in clear refined syrup.

 

Temporary Storage/Cooling: The refined syrup is temporarily stored in a storage tank and begins cooling, awaiting final mixing with other ingredients in a blending tank.

 

After this step, the prepared syrup is degassed and cooled (to near 0°C) before being mixed with carbon dioxide under high pressure to form a carbonated beverage, which is then sent to the filling machine for bottling.

  

   

BLENDING SYSTEM

Function: As a mixing tank, it is used to final mix the base syrup, treated water, and various food additives according to the formula ratio to produce a standardized concentration of "blended syrup." As a storage tank, it is used to store the prepared syrup for the next process.

 

Working Principle: The tank is equipped with a stirrer, which uses rotating blades to tumble and thoroughly mix the materials. The 3-ton capacity determines the batch size for single mixing.

  

  

2.DRINKS MIXER

3.Chiller

Function: Provides a continuous and large volume of low-temperature cooling water (typically 0-4℃) for the mixer. Low temperature is essential for efficient CO₂ dissolution.

 

Working Principle: The refrigerant is cooled through a refrigeration cycle consisting of a compressor, condenser, evaporator, and expansion valve. The cooled chilled water then exchanges heat with the beverage materials through a plate heat exchanger. 60P refers to the compressor power; a higher number indicates stronger cooling capacity.

10.CIP Fully Automated Cleaning System

 

Function: Also known as a "Clean-In-Place" system, it automatically and thoroughly cleans and disinfects the inner surfaces of all tanks, pipes, and valves without disassembling the equipment.

 

Working Principle: The system includes multiple cleaning agent storage tanks (acid, alkali, disinfectant), as well as delivery pumps and control valves. Following a preset program, water → alkali → water → acid → water → disinfectant is pumped into the pipes and equipment to be cleaned in a set sequence at set temperatures, flow rates, and order. This circulates and flushes away residual materials and microorganisms, and finally, sterile water is used for rinsing. The entire process is automatically controlled by a PLC. 1.5 tons refers to the capacity of the cleaning agent storage tanks.

• 4.Filler

  The filling valve consists of a valve seat, exhaust pipe, inflatable valve stem, etc.

  a) Valve seat

  The valve seat is equipped with exhaust valve stem and centering guide. The valve stems are all closed with springs.

  b) Exhaust pipe

  The exhaust pipe determines the liquid level in the bottle. The returned gas returns to the filling tank through the exhaust pipe. The exhaust pipe is threaded, allowing the operator to replace it quickly and easily. The diversion umbrella is installed on the exhaust pipe.

  c) Inflatable valve stem

  The inflation valve stem closes the CO2 return passage in the filling valve. The movement of the external operated valve stem lifts the inflatable valve stem, thus opening the inflation/return air passage.

  The filling valve is located in the filling tank. It remains closed under the filling pressure in the tank. Its working process is as follows:

  When a bottle is pressed against the valve, the valve opening device opens the control valve stem and the CO2 channel opens. Make the pressure in the bottle equal to that in the tank, and the main liquid channel in the filling valve will automatically open. The inflowing main liquid discharges the CO2 and returns it to the tank through an exhaust pinhole and exhaust pipe. When the increasing liquid level seals the exhaust pipe, the pressure in the bottle is gradually higher than the pressure in the filling tank. Under the action of pressure, the filling valve stops filling.

  After the filling process is completed, the filling valve is mechanically closed through the valve closer from the outside, and the CO2 in the bottleneck is slowly released through the exhaust cam (note that the exhaust cannot be too fast, otherwise it will easily bubble).

  There is a mid-position cam between the valve opening device and the valve closing device, which is used to close the inflatable valve in time when a bottle is broken, so as not to cause the pressure of the filling tank to drop rapidly and affect the stability of the liquid level in the tank.

Working Procedure

1.Prepare for pressure

The inflation valve opens, forming a passage between the bottle and the return air channel. CO2 is filled into the bottle through this passage until the CO2 pressure in the bottle is equal to the pressure in the tank.

2.Filling

The filling valve opens, forming a passage between the bottle and the tank, through which liquid is filled in the bottle. At the same time, the CO2 in the bottle flows back to the tank through the return pipe at the same speed, until the liquid in the bottle rises and flows through the return pipe to form pressure balance, the compressed CO2 in the bottle seals the liquid to continue to flow out. When the liquid enters the bottle, it is evenly distributed to the bottle wall through the diversion umbrella to avoid foaming due to impact during filling.

3.Close valve

After the filled bottles have stood for a certain period of time, the liquid valve and the inflatable valve are closed to cut off the passage between the tank and the bottle.

4.Discharge

The exhaust valve opens, creating a passage between the tank and the atmosphere, the pressure in the bottle is thereby released. The final pressure release process is carried out until the bottle is separated from the filling valve.

5.Blowing residual liquid

When the filling valve is located between the bottle outlet and bottle inlet star wheels, the inflatable valve stem opens and then closes after the preset time. In this way, the CO2 gas in the tank will blow out the remaining liquid in the return pipe.
