Pay attention to the application progress and optimize the performance of the whole line

the packaging forms of beverages are diverse. Generally speaking, PET bottles, metal three piece cans, Tetra Pak and so on are common. As we all know, PET bottles have won the favor of consumers with their good performance and transparent appearance, so they have developed rapidly in recent years. Whether carbonated beverages or tea, fruit juice drinks, PET bottle packaging products occupy a large part of the market share. In addition, due to the rapid development of aseptic cold filling technology in recent years, pet is increasingly used as the outer packaging for some low acid beverages such as protein drinks or coffee. It can be seen that the whole line production of PET bottle products can be said to be the lifeblood of many beverage production enterprises, and its excellent performance directly affects the production level of beverage enterprises

The advantages of PET bottle production line are mainly reflected in high-efficiency production. The whole production line of beverages covers a complete set of links such as pre-processing, bottle blowing, filling and post packaging of beverages. Here we only focus on the major packaging links starting from bottle blowing. In this whole line link, every process is very important. If there is a problem with the equipment in one process link, it is bound to affect the production of the whole production line. Therefore, it is particularly important to pay attention to the technical progress of each link and configure their own packaging machinery as needed to improve the integration performance. Moreover, the management level of the beverage factory will also have a great impact on the performance of the whole line. Next, we will analyze how beverage enterprises should optimize the performance of the whole line from each link of the whole line and the overall management

bottle blowing link: not the fastest, just matching

for beverage manufacturers who blow bottles by themselves, the bottle blowing process is a very important process in the production of the whole line of beverages. If the process control in the bottle blowing stage is not good, it will directly affect all links behind the whole line, and then directly affect the performance of the whole line

the two-step bottle blowing process is more conducive to the optimization of the whole beverage line

some large beverage enterprises have higher requirements for product quality, so most of the packaging machinery adopts imported equipment. According to our investigation on the use of bottle blowing equipment by end users of five large beverage enterprises, among the leading beverage enterprises, bottle blowing equipment is almost the world of foreign equipment manufacturers, mainly French and Italian bottle blowing equipment. In recent years, the two-step bottle blowing process has developed rapidly, and more and more beverage enterprises have begun to apply the two-step bottle blowing process. The two-step bottle blowing equipment is mainly represented by the French Sidel company. At present, many beverage bottle blowing equipment suppliers in China mainly develop two-step equipment, because not only the two-step efficiency is relatively high, but also the two-step cost has certain advantages

for the whole line, two-step bottle blowing is more conducive to optimizing the performance of the whole line. Considering the normal operation and failure of the whole line, its advantages lie in the following aspects

during the normal operation of the whole line, there are three problems to be solved to improve the quality of the diaphragm: high porosity, thin film and production efficiency. The operation of the step blowing line requires less energy consumption, and the blown bottles have better performance. When an enterprise configures a two-step production line, the capacity configuration of the blank injection machine and the bottle blowing machine is usually not equal to 1:1, and will generally be configured to 0.8:1 or 0.85:1 accordingly, so that the energy consumption of the whole production line can be effectively reduced. Insufficient bottle blanks will be made up by the amount stored by the blank injection machine when it operates alone in the off-season of production. In addition, using two-step blowing, because part of the stress has been released during the cooling process of the bottle blank in the blank injection link, the second blow will be conducive to the uniform distribution of the thickness of the bottle wall, and the heat resistance, strength and other properties of the bottle will be improved accordingly

when the whole line breaks down, two-step bottle blowing can better reflect certain advantages. The most serious failure of the whole line is the failure of the filling equipment. If the filling machine fails for a long time, it will have disastrous consequences for one-step bottle blowing. If the filling machine fails for a few minutes, the one-step bottle blowing machine can be in the hot standby state. However, if the filling machine fails for a long time, the hot standby time of the one-step bottle blowing equipment will be extended, which will further prolong the particle plasticization process, resulting in a heavy plastic smell of the bottle. If you want to avoid this problem, you can only stop the bottle blowing equipment, but it will take several hours to restart the bottle blowing equipment, which will cause great losses for beverage enterprises. If the enterprise uses two-step bottle blowing, this problem will not exist. When the filling equipment fails, the bottle blank injection system will stop working, and the bottle blowing opportunity will blow the remaining bottle blank in the heating furnace into bottles. Then, nearly all lumia series of Nokia adopt polycarbonate shell, which will be in hot standby state until the fault is eliminated, so the loss to the beverage enterprise is relatively small

the bottle blowing speed should be in line with the filling speed

the technological development of bottle blowing equipment is quite rapid. Major bottle blowing manufacturers at home and abroad are constantly competing for the development and research of high-speed equipment. On average, the speed abroad is quite high, reaching more than 50000 bottles per hour, or even more than 70000 bottles. However, the technical level of domestic suppliers and foreign suppliers is still quite different. At present, the speed of our bottle blowing equipment is 12000 bottles per hour, and 25000 bottles per hour is being developed

however, it should be noted that beverage enterprises should not blindly seek high-speed bottle blowing equipment when configuring the whole line, because the core part of the whole line is the filling equipment, and beverage enterprises usually set the appropriate filling speed first, and the operation speed of the rest of the equipment should match the operation speed of the filling equipment according to the situation. Therefore, as long as the speed of the bottle blowing machine in the whole line configuration can meet the requirements of the production line, there is no need to blindly pursue high speed, otherwise it will cause a waste of operating costs

filling link: the top priority, "one call for all"

the speed of filling equipment determines the speed of the whole line

in the whole production line of beverage enterprises, filling equipment is the top priority. Most beverage enterprises will determine the speed of the required filling equipment according to the product sales and production capacity, and then configure the appropriate filling equipment as needed. The speed of filling equipment plays a decisive role in the speed of the whole line. When the filling speed is determined, the speed of the whole line is basically determined. At the same time, the speed of filling equipment also restricts the running speed of all packaging machinery on the whole line, such as the speed of bottle blowing equipment and the speed of rear packaging equipment. Every beverage enterprise will have one or several main products. The production volume of these products is large, and the packaging appearance and product specifications will not change much in a certain period of time. Therefore, for these products, enterprises will consider high-speed and high-efficiency beverage production lines when choosing production lines, so they will be equipped with some high-speed equipment to ensure the high output of products. In the whole beverage production line, the filling link has a great impact on the quality of products, and the price of filling equipment is also the most expensive, which plays the most important role in the operation of the whole production line. Therefore, many beverage manufacturers have invested a lot in filling equipment at all costs. Like bottle blowing equipment, large domestic beverage enterprises prefer to choose imported filling equipment for performance reasons. According to the current development status of equipment technology, the maximum speed of filling equipment can generally reach more than 60000 bottles per hour, but it is mostly used in the production line of purified water. The filling speed of tea drinks, fruit juice drinks and other products is generally 36000 bottles/hour

aseptic cold filling production line is a double-edged sword

in terms of filling technology, the topic of cold and hot filling is one of the most concerned topics of beverage enterprises in recent years. At present, hot filling is still the mainstream filling process. Carbonated drinks, most bottled water drinks, fruit juice drinks and tea drinks are still filled in the form of hot filling. Now there are more and more aseptic cold filling products in the beverage market, such as Huiyuan, Tongyi, heisong... More and more beverage manufacturers pay more attention to aseptic cold filling technology. It can be said that aseptic cold filling is the more fried, the more "hot"

generally speaking, the aseptic cold filling technology in foreign countries is relatively mature, and the representative manufacturers are SIG, bogoma, etc. Some domestic manufacturers, such as Jiangsu xinmeixing, Lehui (industrial) group and daylong, have also solved the problem of aseptic cold filling external equipment, which is still a long way away

compared with hot filling, aseptic cold filling has obvious advantages in the cost saving of packaging materials and the maintenance of product nutrition and taste. Especially today, when the price of pet continues to rise, the cost savings of sterile cold filling production line for packaging raw materials is indeed enough to make enterprises excited. But at the same time, we should also be soberly aware that for the whole sterile cold filling production line, once the sterile cold filling equipment has problems, the negative impact will also be immeasurable. Moreover, the aseptic cold filling production line has very high requirements for the environment and personnel when running, and the environment in which the equipment is located must reach a certain aseptic level. Once the sterile cold filling production line has problems (such as power failure), the sterility of the sterile room decreases, which cannot meet the requirements for sterility in production, and the equipment must be re purified. This will have an impact on the maintenance cost and the efficiency of the whole line for the production enterprises that fight against every minute

rear packaging link: high automation is favored, so that the whole line "starts and ends"

the rear packaging equipment we want to discuss here includes labeling equipment and packing, sealing and other equipment. As the last link of the whole line, the rear equipment also plays a very important role. In pursuit of high efficiency today, beverage manufacturers are no longer satisfied with manual back-end operation. Many manufacturers have introduced many back-end packaging equipment such as packing machines and sealing machines. In order to optimize the performance of the whole line, the leading enterprises in the beverage industry we interviewed chose foreign rear packaging equipment, such as SMI in Italy

in addition, the chief technical engineer of a well-known enterprise also said in the interview that in order to ensure the smooth production of the whole line, the operation speed of the rear packaging equipment should usually be 15 to 20 percentage points higher than the operation speed of the filling equipment. If the filling speed of a beverage production line is calculated at 36000 bottles/hour, the speed of the rear packaging equipment is designed to be more than 40000 bottles per hour. Sometimes, beverage enterprises will configure two sets of labeling equipment and packing, sealing and other rear equipment to ensure the speed and stability of the whole line

among the suppliers of packaging equipment in the later stage, it is particularly worth mentioning that Taiwan's packaging equipment suppliers are widely recognized by users. They occupy a large market share in the whole rear packaging field with their cost-effective advantages. In particular, Taiwan's labeling equipment is widely used in domestic beverage enterprises. Over the years, Taiwan's labeling equipment has gained a deep foothold in the domestic beverage industry because of its stable performance compared with domestic equipment and its price advantage of being cheaper than imported equipment. Taiwan Peixin and Taiwan Jinhuang are the most influential enterprises in the set of standards. At present, their set of standards equipment and technology are very good
