In modern dairy production enterprises, as consumers pay more and more attention to product quality, hygiene and safety, and packaging aesthetics, traditional manual filling methods can no longer meet the needs of high-efficiency and high-standard industrial production. In order to improve production efficiency, reduce operating costs and ensure food safety, more and more dairy companies have begun to introduce advanced automatic milk filling machines. This equipment not only greatly improves the accuracy and efficiency of milk filling, but also lays a solid foundation for the intelligent development of the entire dairy industry.

　　1. Definition and core functions of automatic milk filling machine

　　Automatic milk filling machine is a fully automatic equipment dedicated to filling liquid dairy products such as milk. It integrates multiple functional links such as automatic bottle sorting, disinfection and rinsing, quantitative filling, capping and sealing, coding, and detection, and is widely used in various packaging forms such as bottled, boxed, and bagged.

　　Its main functions include:

　　Automatic bottle feeding and positioning: accurately deliver empty bottles or packaging materials to the filling station through conveyor belts or star wheel systems;

　　Disinfection and cleaning functions: sterilize packaging containers with high-temperature water or ultraviolet rays before filling to ensure product sterility standards;

　　Quantitative filling system: use flow meters, servo control or isobaric filling methods to accurately control the filling capacity;

　　Automatic sealing/capping: complete the automatic installation and pressing of lids or sealing films;

　　Detection and rejection system: identify whether the filling is in place, whether the lid is tightly sealed, whether there are foreign objects, etc.;

　　Data monitoring and traceability system: set parameters through the touch screen and record production batches to meet traceability needs.

　　2. Special requirements for milk filling equipment

　　As a perishable and highly nutritious liquid food, milk's filling process puts forward higher hygiene and safety standards for equipment:

　　Aseptic filling environment: Equipment operation must meet GMP standards to prevent microbial contamination;

　　Temperature control technology support: Milk is mostly filled at low temperature (2~6℃), and it is necessary to ensure that the filling process does not heat up;

　　Selection of corrosion-resistant materials: All parts in contact with milk must be made of food-grade stainless steel 304/316 to avoid rust;

　　Easy to clean, automatic CIP function: The equipment supports the cleaning in place (CIP) system to reduce cleaning time and improve efficiency;

　　Foam control design: Prevent bubbles from being generated during the filling process to affect capacity and sealing.

　　3. Advantages of automatic milk filling machine

　　High filling accuracy and reduced waste: The high-precision filling system ensures the consistent capacity of each bottle of milk, effectively controls raw material loss, and improves product yield.

　　High degree of automation and reduced labor costs: The entire process is automatically operated, greatly reducing the need for manual operation and improving production stability and sustainability.

　　Strong sanitation and safety guarantee: Adopt closed filling system to avoid air and dust from entering, and ensure that the finished product meets national food safety standards.

　　Strong compatibility, suitable for a variety of packaging: Support glass bottles, plastic bottles, roof boxes, Tetra Pak and other packaging forms, one machine for multiple uses, strong flexibility.

　　Intelligent control and remote monitoring: Support PLC programming control, touch screen operation and IoT remote management, which is convenient for factory digital transformation.

　　As an important equipment for the upgrading of dairy industry, automatic milk filling machine is helping more and more companies to achieve the transformation from manual batch to intelligent and efficient. It not only improves the production efficiency and product quality of enterprises, but also guarantees consumers' trust and demand for healthy, nutritious and safe dairy products. As the dairy market continues to expand, automatic milk filling machine will also continue to develop in a smarter, cleaner and more environmentally friendly direction.
