The Development History of Rice Vacuum Packaging Machines
The Early Exploration Stage (Early 20th Century - Mid - 20th Century)
In the early 20th century, vacuum technology began to develop gradually. However, the relevant equipment was mainly used for some special needs in the industrial field, such as the manufacturing of electron tubes, and was far from being applied to rice packaging.
By the mid - 20th century, with the development of the food industry, people started to attempt to apply vacuum packaging technology to food preservation. Some simple vacuum packaging equipment initially appeared, with a rather rudimentary structure. It was mainly used by some small food factories for packaging a small quantity of products. For granular products like rice, the packaging effect was not ideal. The packaging efficiency was low, and it was difficult to achieve large - scale production.
The Technological Development Stage (Mid - 20th Century - Late 20th Century)
From the 1960s to the 1970s, with the continuous progress of vacuum technology and the improvement of mechanical manufacturing processes, vacuum packaging machines specifically designed for granular materials such as rice began to emerge. These devices adopted more advanced vacuum pump technology, which could extract the air inside the packaging more quickly, improving the vacuum degree of the packaging and thus better maintaining the quality of the rice. At the same time, there were improvements in the structural design of the packaging machines, with the addition of material conveying and metering devices, enabling more accurate quantitative packaging of rice.
From the 1980s to the 1990s, microprocessor technology was introduced into rice vacuum packaging machines. Controlled by a microprocessor, the packaging machines achieved automated operation, and could precisely control various parameters in the packaging process, such as the vacuuming time, sealing temperature, and sealing time. In addition, they were equipped with fault diagnosis and alarm functions, making it convenient for operators to detect and solve problems in a timely manner, which improved the stability and reliability of the equipment. Rice vacuum packaging machines began to be widely used in rice processing enterprises.
The Stage of Intelligent and Diverse Development (Early 21st Century - Present)
Since the beginning of the 21st century, with the rapid development of computer technology, sensor technology, and artificial intelligence technology, rice vacuum packaging machines have been developing towards intelligence and diversity. Intelligent rice vacuum packaging machines are equipped with advanced sensors, which can automatically detect information such as the flow rate, weight of the rice, and the position of the packaging materials, realizing a fully automatic packaging process. Meanwhile, the equipment can be connected to the enterprise's production management system through the network, enabling remote monitoring and data analysis. Enterprise managers can understand the operating status and production data of the packaging machines in real time, so as to carry out production scheduling and quality control.
In terms of diversity, in addition to the traditional regular packaging specifications, rice vacuum packaging machines can meet the diverse needs of different customers for packaging forms and packaging quantities, such as small packages, large packages, and special - shaped packages. Some high - end rice vacuum packaging machines also have the function of filling inert gases such as nitrogen, further extending the shelf life of rice and enhancing the freshness preservation effect of rice. Moreover, to adapt to rice processing enterprises of different scales, various models and capacities of rice vacuum packaging machines have emerged on the market, ranging from small single - unit equipment to large automated packaging production lines, meeting the needs of different users.
