Cobi pet food liquid packaging PET darling

For pasteurized dairy products and other perishable dairy products and juices, the appearance of PET bottle packaging offers a new way to ensure their long shelf life at room temperature. Since PET blow molding and filling lines are targeted at factories of modern companies, improving the overall efficiency of PET packaging becomes more important. In the process of technological innovation, how to combine the blowing, filling and capping of PET bottles is a technical problem. This situation has continued until the time when Sidel launched the Combi machine seven years ago. Today, 100 Combi machines all over the world continue to create surprises.

The birth of the birth of the Combi machine stems from the concept that within a single piece of equipment, the liquid PET bottle is packaged in three main steps. This is because its creator - Sidel has always been pursuing optimal production. The concept of controlling hygienic packaging conditions and reducing the floor space of equipment. This concept applies to all liquid foods, from carbonated drinks, sensitive drinks, to semi-liquid products (such as ketchup and mayonnaise). Semi-liquid products (such as ketchup and mayonnaise). In 1997, the Combi machine that produced gas-free drinking water took the lead in entering the market. This type of machine is still the majority in the sold Combi. This proves that the Combi machine can face fierce competition in the water market. Combi machines are a better choice for dairy products, fruit juices and even carbonated drinks. Today, seven years later, the Combi machine was used in 38 countries, indicating that this concept has clearly penetrated all liquid food markets on all continents.

Advantage Combi is a new industrial concept of PET bottle packaging, which can fully increase the production capacity and hygiene of PET bottles. The Combi machine can be equipped with 4 to 28 blow molds, with production speed ranging from 5,000 to 42,000 bottles/hour, and can be produced by any of Sidel's filling technologies. Several steps are performed within a single device and the process can be fully controlled at any production speed. This reduces interface problems and improves overall production. These advantages are similar to the inclusion of capping in the filling machine. The integrated concept of the Combi machine eliminates the necessary air transport links in the traditional solution. The positive transport of bottles from blowing to filling reduces the bottle weight and increases the freedom of bottle design. This significantly reduces the cost of materials and energy consumption. Because of the small footprint of the equipment, the Combi can provide the perfect solution for today's planning needs and the humanized design of the plant. Only one operator is required to perform simple operations on site. The blowing bottle is closely connected with the filling operation. The stainless steel hood with no negative pressure inside, the air filter system, and the surface and product circuit are clean. All of these elements ensure the sanitary status of the whole production process. Therefore, the Combi machine not only protects the PET package from damage, but also keeps the liquid food safe.

The comprehensive technological advantages and equipment innovation of the Sidel Group drive the progress and improvement of the Combi. Recently, the Combi machine has produced a half-liter PET bottle for carbonated beverages at a rate of 42,000 bottles/hour. It has written a new world record and has become a major technological innovation. Sidel has developed a pressure-free collection container consolidation platform. In order to further compact the machinery and equipment and improve the integrated packaging solution, the Combi machine has eliminated this link, simplified the operation, and increased the range of adaptation of various bottle types.

The dairy industry in the application <br> <br> from China liquid food market, the application of PET packaging in the beverage industry is already quite extensive and sophisticated, but the application in the dairy industry is relatively small. In fact, except for white milk, which needs pasteurization and special processing to store it, any flavored dairy products can be stored in conventional PET bottles. Therefore, PET packaging holds great promise in the dairy industry. Based on Sidel's PET blowing and filling expertise and experience with aseptic filling of dairy products, the emergence of the Combi will strongly promote the development of dairy PET packaging.

As an integrated packaging system that integrates blowing, filling and sealing functions. Under the premise of cold chain sales, the ESL (long shelf life of cold chain sales) dairy products filled with this system do not require chemical additives and do not need to be rinsed to make the storage period of milk and lactic acid drinks separately. Arrived at 3 weeks and a month. In addition, this system requires no air conveyor belt between the blower and the filler, which saves a considerable amount of workshop space.

There are four Combi models for milk packaging in PET bottles, suitable for bottles of different capacities from 200 ml to 2 litres.

* SF Combi Classic standard models include Sidel SBO blow moulders and FMf series capacity fillers with flow meters. This packaging line is used to fill pasteurized dairy products sold in cold chains, with a shelf life of 2 to 5 days.

* SF Combi selec Enhance models: Pasteurized milk products with a shelf life of 2 to 3 weeks, or lactic acid drinks with a shelf life of 1 month for cold chain sales. The packaging line includes a preform sterilization module, an SBO blow moulder and an FMf series volumetric filling machine with a 100-layered flowmeter.

* The Combi Ultra model also includes a preform sterilization module, but adds a step to hydrogen peroxide sterilization. The accompanying SBO blow-molding machine uses sterile air blowing. The filling machine is the FMf series capacity filling machine with a 100-layer flow meter. This system is suitable for cold-chained flavored dairy products, milk coffee, milk tea, and ultra-high temperature instantaneous sterilized tea beverages. The shelf life is 2 to 3 months.

* SF Combi Aseptic aseptic models for long shelf life dairy products sold at room temperature. This filling line includes the SBO blow moulder, decontamination and rinsing module (washed with PAA superacid and disinfectant water), an aseptic filler (Fmi series, capacity flow meter with overpressure protection) and Two process platforms: "Logiface" (used to control the sterilized dairy feed filter, and the dry cap with sterile air, the CIP field cleaning device inside the machine and the SIP field sterilizer) and "PAA" (used to control the PAA Peracetic acid, disinfectant and SOP field machine external sterilizer supply and circulation). The model is suitable for flavored milk, milk coffee, milk tea and tea drinks. SF Combi Classic standard models, SF Combi Select enhanced models, SF Combi Aseptic aseptic models can be up to 32,000 bottles/hour depending on filling capacity. Combi Ultra's ultra-clean models have a maximum speed of 24,000 to 28,000 bottles/hour depending on the process and bottle capacity.

As a packaging medium, PET has its flexibility and rapidity, enabling manufacturers to quickly bring new products and their corresponding series of products to the market, and also to achieve diversification and individualization of packaging. It can be foreseen that PET bottle packaging will further develop with the rapid increase in demand for pasteurized dairy products and fruit juices. Combi machines with excellent performance will inject more vitality into the liquid food market.
