Pastry-based foods mostly refer to flour, oil, sugar, salt as the main raw materials, add eggs, milk, fruits, cream, nuts and other auxiliary materials, the production process includes baking, steaming, frying and so on. Bread, cakes, snacks, etc. that are common in our daily life are all pastry foods. In recent years, the pastry and food market has been developing steadily, with a market sales growth rate of 7.28% in 10 years. With the consumption upgrade, the compound growth rate of the pastry food market is expected to reach 14.10% in the next five years.
Nowadays, people's life rhythm is accelerating continuously, and the requirements for pastries are also shifting to portability and long-term maintenance. As a result, the share of pre-packaged pastries in the market is increasing. With the help of food machinery, the degree of automation of the production of pre-packaged pastries is constantly improving. Among them, the application of automatic packaging equipment in pre-packaged cakes is indispensable, not only can prevent human safety hidden dangers, but also improve packaging quality.
Packaging equipment can automatically complete the main processes including filling, wrapping, sealing, etc. At present, there are many types of packaging equipment on the market, including vacuum packaging machines, stretch film packaging machines, bag-feeding packaging machines, nitrogen-filling packaging machines , Pillow packing machines, etc. Pastries are relatively "fragile" foods. Therefore, the packaging cannot use vacuum form, to avoid the impact of the product shape and mouth feeling caused by atmospheric compression.
In the packaging of pastry foods, a pillow packing machine is relatively common equipment. A Pillow packaging machine is a continuous packaging device, which longitudinally seals and transversely seals the packaging film wrapped with pastry in the former, with fast temperature and high stability. The equipment can be used not only for the packaging of transparent or unbranded packaging materials, but also for the packaging materials pre-printed with patterns and trademarks. The packaging speed is fast and the quality is high.
Pillow type packaging machines mostly use PLC control systems, and the degree of packaging automation is extremely high. The packaging film cutting tool can perform reciprocating cutting, which is accurate in one step. The incision will not cause the packaging material to stick to the knife or hot film, etc., and the packaging seal is beautiful. However, in the packaging process of printing packaging materials, equipment manufacturers should pay attention to the influence of factors such as the stretching of the packaging material and mechanical transmission during the operation of the equipment, which makes the sealing and cutting position error.
To eliminate this error, equipment manufacturers also need to improve the automatic positioning capabilities of the equipment. Enterprises can install a continuous photoelectric automatic positioning system in the equipment to eliminate possible positioning errors in the packaging process. At the same time, it is also necessary to improve the level of intelligence of the equipment, to implant intelligent servo technology in the equipment, integrating motion control technology, DSP technology, PLC technology, field bus technology and other modern control technologies into one, to promote the equipment to be intelligent, network Development of modularization, modularization and digitalization.
Nowadays, consumers prefer pre-packaged pastries with medium and long shelf life such as 20 days and 45 days. In the production of such pastries, automated packaging equipment is indispensable. Pillow type packaging machine has a high degree of automation and fast packaging speed, which can well improve the production efficiency and packaging quality of cakes. For the pillow packaging machine industry, in order to continue to grow and develop, it also needs to develop in the direction of faster and more stable packaging, low energy consumption, low manual, low waste rate and so on.
