Soft drink filling machines are a type of beverage filling equipment widely used in the beverage filling industry. Due to the varying gas conditions inherent in the filling process of beverages, as well as differences in product performance, models, and processing methods, soft drink filling machines can be broadly categorized into several major types. These primarily include atmospheric carbonated beverage filling machines, pressurized carbonated beverage filling machines, and vacuum carbonated beverage filling machines. The primary form of carbonated beverage filling machines is the pressurized carbonated filling machine, which is designed to achieve efficient processing machinery.
This equipment adopts a reliable, user-friendly, and easy-to-maintain microcomputer control system and a pneumatic control system. It integrates the entire process of bottle washing, filling, and capping under enclosed conditions, effectively preventing potential secondary contamination of purified water or mineral water during the filling process. This ensures truly aseptic filling, making it currently the ideal purified water/mineral water filling equipment in the domestic market.
For atmospheric carbonated beverage filling machines, this form is similar to carbonated beverage filling machines and allows for filling through liquid gravity. The equipment employs a reliable, user-friendly, and easy-to-maintain microcomputer control system and a pneumatic control system. It integrates the entire process of bottle washing, filling, and capping under enclosed conditions, effectively preventing potential secondary contamination of purified water or mineral water during the filling process. This ensures truly aseptic filling, making it currently the ideal purified water/mineral water filling equipment in the domestic market. Atmospheric carbonated beverage filling machines can be divided into two types: timed carbonated beverage filling and fixed-volume carbonated beverage filling. They are more suitable for filling low-viscosity, non-carbonated liquids such as fruit juice and milk.
As for vacuum carbonated beverage filling machines, the bottle pressure is lower than atmospheric pressure. This design offers broad adaptability to material viscosity, high filling efficiency, and a simple structure, making it suitable for oils and fruit wines. The commonly used pressurized carbonated beverage filling machine is a typical carbonated beverage filling machine that operates under pressure higher than atmospheric pressure. Pressurized carbonated beverage filling machines are also divided into two types: one is isobaric carbonated beverage filling, and the other involves a storage tank pressure higher than the bottle pressure, allowing liquid to flow into the bottle through pressure difference. The latter method is often used in high-speed production lines, while the former, where liquid flows into the bottle by its own weight, is more commonly preferred.
Additionally, traditional carbonated beverage filling technology and equipment can no longer meet the quantitative filling requirements of pulp-containing beverages. The sealing technology of carbonated beverage filling machines differs from traditional isobaric filling technology in that the filling volume is controlled by a flow meter. As a sealing technology for carbonated beverage filling machines, it is also an extremely critical operation at the end of the processing task, which encompasses a series of measures such as sterilization and sealing. It is necessary to effectively eliminate algae proliferation and spores, ensure the sealing of caps in medical-grade clean standard rooms, and truly achieve a series of unmanned procedures in the cleanroom during the sealing process of beverage filling machines.
