Application and Development of Filling Machine for pickled Chinese cabbage Fish Paste and Watermelon Paste in Modern Food Processing Industry

With the continuous development of China's food industry, the market demand for all kinds of seasoning sauces continues to rise. As two characteristic sauces favored by consumers in recent years, pickled Chinese cabbage fish sauce and watermelon sauce have gradually expanded their production scale and become increasingly dependent on filling equipment. As the core equipment of the sauce production line, the filling machine directly affects the filling accuracy, production efficiency, and hygiene and safety level of the product. This article focuses on the technical characteristics, selection points and development trend of the filling machine for pickled Chinese cabbage fish sauce and watermelon sauce.

Pickled Chinese cabbage fish sauce is a compound sauce based on pickled Chinese cabbage, pickled peppers, fish sauce and a variety of spices. It is thick, contains certain granular materials, and has certain corrosivity and adhesion. Watermelon sauce is a sauce made mainly from watermelon flesh, supplemented with sugar, salt, and fermentation bacteria. It has a high water content and relatively good fluidity, but it is prone to layering and dripping during the filling process. These two sauces have significant differences in physical properties, therefore different requirements are put forward for the adaptability of the filling machine.

At present, the common sauce filling machines in the market are mainly divided into three categories: piston filling machines, rotary pump filling machines, and screw filling machines. The piston filling machine is suitable for filling materials with high viscosity and particles. It has good adaptability for pickled Chinese cabbage and fish sauce, which can avoid particle breakage and ensure the stability of the filling volume of each bottle. The rotary pump filling machine is more suitable for processing sauces with certain fluidity and requiring gentle conveying. It performs well in watermelon sauce filling operations and can reduce damage to the flesh tissue. Screw filling machines are commonly used for quantitative filling of medium viscosity sauces. They have a compact structure and are easy to adjust, making them suitable for small and medium-sized production enterprises.

When choosing filling machines for pickled Chinese cabbage fish sauce and watermelon sauce, enterprises should pay attention to the following aspects. Firstly, the filling accuracy is crucial. The net content of sauce products directly affects consumer rights and corporate reputation, and filling errors should be controlled within the allowable range of national standards. Secondly, there are material requirements. Due to the acidic or high salt content of the sauce, the contact part between the filling machine and the material should be made of food grade stainless steel, such as 304 or 316L stainless steel, to ensure corrosion resistance and food safety. Once again, the convenience of cleaning is important. Sauce residue can easily breed bacteria, so the filling machine should have quick disassembly and online cleaning functions. In addition, the degree of automation is also an important factor to consider. The fully automatic filling machine can integrate processes such as bottle sorting, filling, capping, and labeling, significantly improving production efficiency and reducing labor costs.

From the perspective of technology development trend, the filling machine for pickled Chinese cabbage fish sauce and watermelon sauce is evolving towards intelligent, flexible and green direction. In terms of intelligence, the combination of PLC control system and human-machine interface can achieve functions such as parameter memory, fault alarm, and remote monitoring. In terms of flexibility, the same filling machine can adapt to the production needs of different specifications and varieties of sauces by replacing the filling valve and adjusting parameters. In terms of greening, the application of energy-saving motors and low-noise designs can help reduce energy consumption and improve the working environment in the workshop.

The filling machine for pickled Chinese cabbage fish sauce and watermelon sauce plays an indispensable role in the food processing industry. Enterprises should scientifically select suitable filling equipment based on their own product characteristics, production scale, and budget conditions, and pay attention to the daily maintenance and upkeep of the equipment, in order to ensure stable product quality, improved production efficiency, and sustained economic growth of the enterprise.
