Vacuum capping machine for melon seed paste and black pepper paste: packaging edge device for vacuum sealing

The vacuum capping machine for melon seed paste and black pepper paste is one of the important equipment in the modern food packaging industry, which is widely used in the packaging production line of all kinds of sauce products. This equipment ensures freshness of soy sauce products in packaging process and prolongs shelf life through efficient vacuum sealing technology, and improves market competitiveness of products.

The working principle of the vacuum cap screwing machine is to extract the air in the packaging container through the vacuum pumping system to form a vacuum environment for cap screwing and sealing immediately. This process prevents the oxidative deterioration caused by the contact of soy sauce products with air, and inhibits the growth of microbes, thereby significantly prolonging the shelf life of the product. Vacuum packaging is especially important for oxidizing and perishable foods such as melon seed and black pepper sauces.

In terms of equipment structure, the vacuum cap screwing machine is usually composed of conveying system, vacuum pumping system, cap screwing system and control system. The conveying system is responsible for orderly sending the filled sauce bottles into the working area; The vacuum pumping system quickly extracts the air in the bottle through the vacuum pump; The cap screwing system adopts high-precision torque control technology to ensure that the cap is tightened in place without damaging the bottleneck; The control system integrates the automatic operation interface, which is convenient for adjusting parameters and monitoring the production status.

For the characteristics of melon seed paste and black pepper paste, special attention shall be paid to several aspects in the design of vacuum cap screwing machine. First of all, due to the high viscosity of the soy sauce, the equipment needs to be equipped with a drip prevention device to avoid the overflow of the soy sauce and pollution of the equipment during the capping process. Secondly, according to different specifications of bottle types and caps, the equipment shall have the function of quickly changing moulds to meet the needs of multiple varieties of production. In addition, given the potential for soy sauce to contain particles, critical parts of the equipment need to be made of wear-resistant materials to extend their life.

The vacuum cap screwing machine generally adopts PLC control system, which is characterized by high automation degree and easy operation. Operators only need to set parameters such as vacuum degree and screwing torque through the touch screen, and the equipment can automatically complete the whole packaging process. Some models are also equipped with visual detection system, which can automatically identify the defects of the bottle cap and remove unqualified products, further improving the packaging quality.
In terms of hygiene and safety, the vacuum cap screwing machine is usually made of stainless steel, meeting the food hygiene standard. The equipment surface shall be smooth and free of dead corner, convenient for cleaning and disinfection. Some models are also equipped with CIP cleaning system, which can automatically complete the cleaning inside the equipment and greatly reduce the risk of food pollution.
With the progress of technology, the new generation of vacuum cap screwing machine also has a significant improvement in energy conservation and environmental protection. The vacuum pump with frequency conversion technology can adjust the power according to the actual demand, which can reduce the energy consumption. Meanwhile, the optimized sealing structure reduces the consumption of compressed air and makes the equipment operate more economically and environmentally.
For manufacturers of melon seed and black pepper sauces, there are many factors that need to be considered in selecting the proper vacuum capping machine. First of all, the capacity requirements of the equipment shall be determined according to the production scale. Generally, the semi-automatic model can be selected for small and medium-sized enterprises, while the full-automatic production line is more suitable for large enterprises.

Second, the product characteristics shall be considered, such as the viscosity of sauce, particle size and other factors will affect the equipment selection. In addition, after-sales service and technical support are important considerations.
