Application analysis of beer packaging production line (Part 1)

I. relevant market

beer packaging machinery is a single industry-specific equipment. The main market of China's beer packaging machinery is in Southeast Asia, Africa, Russia and other developing countries. The international market is basically monopolized by German companies such as Krones and KHS

10 years ago, China once exported a 20000 bottle/hour beer production line to Cambodia and several 8000 bottle/hour and 12000 bottle/hour beer production lines to Vietnam. At that time, the domestic beer machinery manufacturers used lm358 to carry out voltage measurement on the output signal. Due to the lack of comprehensive strength, they did not actively continue to explore the international market and gave up the Southeast Asian market for a long time. Only pay attention to the development of the domestic market. Before 1986, China's medium and high-end beer packaging equipment market was basically monopolized by German companies such as h&k, Sen, Krones, etc., and China could only produce low-end products - beer filling production lines with less than 8000 bottles/hour, and there was a big gap in technology compared with foreign advanced products. In 1986, the former China Light Industry Machinery Corporation of the Ministry of light industry introduced a 20000 bottle/hour beer production line from the German KHS company through the combination of technology and trade. In 1993, it introduced a 36000 bottle/hour beer bottling production line with contemporary technical level from the KHS company. Through the introduction of technology, digestion and absorption, the domestic processing technology and technology have undergone leapfrog development. Since then, the market share of domestic beer packaging equipment has increased steadily. Especially in recent years, the share of domestic equipment in China has increased rapidly. It is roughly estimated that the proportion of new domestic beer equipment purchased by domestic beer production enterprises has reached about 90%. The imported equipment selected are mainly some bottle and box detection equipment, electronic valve filling machine and a small number of high-speed labeling machines for pure draft beer. Recently, from the situation of beer packaging production lines purchased by Tsingtao beer, Yanjing Beer, China Resources beer, Kingway beer, Harbin beer, lion beer and other major beer groups, except for bottle and box detection equipment and individual filling machines, almost all of them are domestic equipment; More typically, Heineken Asia Pacific beer group, a foreign-funded international famous brand, also purchased in China for the first time two bottled beer filling production lines of 40000 bottles/hour and 20000 bottles/hour made by Guangdong Light Industry Machinery No. 2 Factory Co., Ltd. for plastic requirements of universal testing machines

II. Related technologies

at this stage, the production capacity of a single beer bottling production line designed in China can only reach 48000 bottles/hour (640ml). The maximum production capacity of a single beer bottling production line that can be produced in China has reached 40000 bottles/hour, while Germany has reached the level of 70000 bottles/hour, compared with which we still have a big gap. However, from the technical indicators of the existing medium and low-speed whole line equipment, the domestic technical level is basically close to the imported equipment, and the whole line efficiency of the domestic beer packaging production line can reach 85% - 90%, which is close to the level of similar foreign equipment. However, there is still a certain gap between the efficiency of some single machines and the imported ones. This gap can be made up by increasing the bottle storage capacity of the bottle conveying system and configuring individual single machines with slightly larger production capacity

the cleaning rate of domestic bottle washing machine can reach 99%, which is better than that of imported equipment. Because the domestic bottle washing machine is designed and produced according to the domestic source of recycled bottles, the soaking time of its lye is basically more than 10 minutes, and there is no problem washing recycled bottles. While the design benchmark of the foreign bottle washing machine is about 8 minutes, and the filling liquid level accuracy of the domestic filling machine has reached ± 4mm. If it is specially designed, it can reach more than 98%, the oxygen increase can be controlled below 0.04ppm, and the qualification rate of the gland can reach more than 99.9%, These indicators have basically reached the level of imported equipment, which shows that the level of domestic design and processing technology has made considerable progress

the core technology of sterilization machine is the control of sterilization Pu value. The domestic sterilizer adopts the Pu value fuzzy logic system to automatically control the Pu value, and also adopts the automatic cold water cooling device in the high-temperature area and insulation area, so that the Pu value control accuracy and the maximum increase of Pu value during temporary shutdown reach the level of imported similar equipment

III. related equipment

1. container handling machine

at present, the main types of domestic container handling machines are: four-bar structure and flat moving structure, which belongs to intermittent packing and unloading, and the single machine capacity can only reach more than 50000 bottles per hour at present; In addition to the above two types abroad, there is also a rotary continuous loading and unloading machine, whose single machine capacity can reach more than twice that of domestic equipment. In addition, in China, in order to improve the loading and unloading output of domestic loading and unloading machines, the four-bar loading and unloading machine is currently used most, which is characterized by mature technology, simple structure, practicality and low cost. Recently, some users began to use the translational loading and unloading machine, which is characterized by the adjustable separation of horizontal and vertical movements, which has certain advantages for carton loading

2. Bottle washing machine

the main models of domestic bottle washing machines are: single end immersion bottle washing machine and double end immersion bottle washing machine

the main models in foreign countries are: single end, double end immersion and dual-purpose continuous label removal new bottle washing machines for plastic bottles and glass bottles

the dual-purpose continuous label removal new bottle washing machine for plastic and glass bottles is still blank in China. Its biggest feature is that the label paper is separated from the bottle, which can be removed in a short time, which greatly reduces the pollution of the label paper to lye, and overcomes the problem of fibrosis of the label paper

at present, the bottle washing machine used in China is still a single instrument, which can be equipped with a photography device for microscopic photography. The end type accounts for the majority. Its characteristics are mature technology, strong adaptability, low cost and energy saving. But recently, more and more users choose to use double end bottle washing machine, which is mainly affected by foreign trends. In developed countries, due to the legal requirements for the classification of garbage and recyclables, the waste label paper discharged by the single end bottle washing machine cannot be separated from broken glass. On the contrary, the waste label paper discharged by the double end bottle washing machine does not contain broken glass, and the waste label can be recycled by pressing it dry by a dryer. Therefore, the use of double end bottle washing machines abroad has gradually become the mainstream

at present, the production capacity of domestic common bottle washing machines is less than 48000 bottles/hour, which is quite different from that of foreign countries. The main influencing factors are:

(1) transportation problems. Due to the relatively backward design of the height and width of tunnels, bridges and toll stations on roads and railways, the transportation of large equipment is limited

(2) manufacturing process problems
