Basic Concepts of Aseptic Filling System
Aseptic filling:
The process of filling and sealing commercially sterile liquid materials and sterilized packaging materials in a sterile environment allows the food to be transported and stored at room temperature within the shelf life.

Aseptic Filling Machine Mainframe Components and Working Content
Bottle Sterilization System
For sterilization inside the bottle, the atomized hydrogen peroxide passes through the heating device, and the temperature is raised to 130°C (<60°C when it reaches the bottle), and then distributed to the bottle dry sterilization system of the filling equipment through the hydrogen peroxide atomizing distributor.
The sterilization unit is equipped with a spray rod of the atomized hydrogen peroxide that can automatically raise and lower the dispenser. The effective length of the spray rod is generally 5mm (when the bottle type is different, the length of the spray rod is also designed according to the bottle type), which fully ensures that the inside of the bottle is completely covered by the high-temperature atomized hydrogen peroxide without dead corners, so as to achieve a completely effective sterilization effect.
This technology can also set different sterilization and blowing parameters according to the difference in bottle types to ensure that it can achieve effective sterilization, safe residue, and prevent bottle deformation.

Hot Air Decomposition System
The products of hydrogen peroxide decomposition are harmless oxygen and water.
The decomposition rate of hydrogen peroxide is extremely slow at room temperature. The decomposition rate of hydrogen peroxide can be quickly increased after heating.
Reliability: >LOG 6 bottle sterilization capacity (according to national standard indicator bacteria)
Safety: <0.5ppm H2O2 residual amount in the bottle at T0

Filling System
The filling system is one of the cores of this unit. The upper structure of the filling system is all outside the 100-level room. There are only the filling valve port and bottle clamping device in the 100-level room. This greatly simplifies the internal structure of the equipment and maximizes the process environment of the filling area.
Non-contact filling is used to avoid repeated contamination.
The original dual-speed filling technology is used. In the filling process, common products on the market do not foam.

Capping System
In view of the weaknesses of the traditional mechanical gear-transmitted capping system, such as the inability to adjust the capping speed, the impact movement of the capping head, and the difficulty of adjusting the capping torque technology.
The servo motor can control the speed, and the position accuracy is very accurate. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or speed output on the motor shaft.
The capping servo system of the equipment sets the capping parameters according to the beverage production process through the human-machine interface, including capping torque, capping speed and total capping angle, etc.
The capping system controlled by the servo motor can freely set the parameters of the capping servo motor through the human-machine interface, setting and modifying PLC parameters when changing product lines.
Atomized Hydrogen Peroxide Center Station
The equipment system consists of a hydrogen peroxide (hydrogen peroxide) atomization unit, a sterile water unit, a sterile gas unit and a waste gas recovery unit; SIP/SOP and sterile water preparation are completed in this system.

Cleaning Center Station
The cleaning center station adopts Siemens' top 1500PLC control, and valves and instruments use first-line brand accessories.
The cleaning center station adopts full automatic control according to the needs of production and maintenance. The system can automatically complete seamless switching between production and maintenance (CIP/SIP/COP) according to the needs of the process, and there is no need to manually switch valves during the whole process.
The cleaning center station also has a steam barrier function. The core component of the system is a four-way steam barrier anti-mixing valve. In this way, when switching between production and cleaning, the cleaning and sterilization of the steam barrier can completely prevent different liquids in the process pipeline from mixing and contaminating each other.

Automatic Capping and Cap Disinfection System
The automatic capping system consists of a cap bin and a cap sorting machine.
The cap disinfection system consists of a cap sterilizer, cap hot air decomposition, and cap conveying.
The cap sterilization adopts dry sterilization technology with gasified hydrogen peroxide as the sterilization medium.
The cap transmission is single-row forward to ensure that the sterilization time of all caps is consistent; hot sterile gas is used for high-speed blowing to ensure that the residual sterilization medium meets the standard.
Reliability: > LOG 6 cap sterilization capacity (according to national standard indicator bacteria)
Safety: < 0.5ppm H2O2 residual in the cap at T0 time.
