With the continuous improvement of people's living standards, the demand for various convenience foods has also increased greatly, which has further driven the rapid development of China's food packaging industry. Vacuum packaging machine is one of the fastest developing packaging machinery, with broad development prospects. The vacuum packaging machine is put into the packaging bag of the packaged material through the air extraction nozzle, the air is evacuated, the air is exited, and then the sealing is completed.
Vacuum packaging technology originated in the 40s of the 20th century. Since the successful application of polyester and polyethylene plastic film in 1950, vacuum packaging machine has been rapidly developed, and its technical development trend is mainly reflected in high productivity, automation, stand-alone multi-function, composition production line.
High productivity:
The productivity of the vacuum packaging machine has developed from several pieces per minute to 10 pieces, and the productivity of the thermoforming-filling-sealing machine can reach more than 500 pieces / min.
Automation:
The automatic vacuum packaging machine has the function of vacuuming, sealing, printing and cooling at one time.
Stand-alone multi-function:
Multi-function on a single machine, which can easily expand the range of use. To achieve single-machine multi-function, it is necessary to adopt modular design, and through the transformation and combination of functional modules, it becomes a different type of vacuum packaging machine suitable for different packaging materials, packaging items, and packaging requirements.
Composition production line:
When more and more functions are needed, concentrating all functions on a single machine will make the structure very complex, operation and maintenance is not convenient, then several machines with different functions and matching efficiency can be combined into a more functional production line.
RITO vacuum packaging machine
Adopt the latest technology:
1. Part of the air (oxygen) in the packaging container is removed, which can effectively prevent food spoilage.
2. The use of packaging materials with excellent barrier (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of packaging content substances, which can avoid food weight loss, loss of taste, and prevent secondary pollution.
3. The gas inside the vacuum packaging container has been removed, which accelerates the conduction of heat, which can improve the heat sterilization efficiency and avoid the rupture of the packaging container due to the expansion of the gas during heating and sterilization.
4. RITO Machinery adopts new technology, and adopts a large number of inflatable packaging instead of vacuum packaging in packaging technology, closely combining the research of inflatable components, packaging materials and inflatable packaging machines; In control technology, more application of computer technology and microelectronics technology; In terms of sealing, heat pipe and cold sealing technology are applied, and advanced devices can also be installed directly on the vacuum packaging machine, such as high-precision combination scales for coarse-grained materials equipped with controllers; On rotary or vacuum packaging machines, advanced and high-speed circular arc cam indexing machinery is applied.
In the food industry, vacuum packaging applications such as:
Cooked products such as: chicken thighs, ham, sausages, etc.;
Pickled products such as: all kinds of pickles, soy products, preserved fruits, etc.;
Packaging of raw products such as tea, peanuts, shrimp, corn and other foods.
A wide variety of food products that need to be kept fresh are increasingly vacuum-packed. Vacuum-packed food has a long shelf life, which greatly extends the shelf life of food.
