The vacuum cap screwing machine for rice sauce and mixed sauce is an important equipment in the modern food packaging industry, which is widely used in the condiment production field. This kind of equipment is mainly used for vacuum sealing packaging of various kinds of sauce products, which can extend the shelf life of products, maintain food flavor and improve the market competitiveness of products.

The working principle of the vacuum cap screwing machine is to extract the air in the bottle through the vacuum pumping system to form a negative pressure environment and complete the cap screwing and sealing. The equipment is mainly composed of bottle inlet conveyor belt, vacuum pumping system, cap screwing mechanism, bottle outlet conveyor belt, etc. The whole workflow is highly automated, easy to operate and stable in production efficiency.

The following key factors need to be considered when selecting the vacuum cap screwing machine for rice sauce and mixed sauce:

The first is productivity. Select equipment with proper capacity according to the actual output demand of the enterprise. For small production lines, 20-30 bottles/minute equipment can be selected, while for large production enterprises, 60-100 bottles/minute high-speed models shall be considered.

Secondly, the applicable bottle type range. Different brands of soy sauce products have different packaging bottle types, and the equipment shall have the adjustment function to adapt to various specifications of bottles and lids. The equipment is usually equipped with a quick change device, which can complete the bottle type conversion in a short time.

Vacuum degree control is another important indicator. The rice paste and mixed paste products have high requirements on vacuum degree, generally reaching vacuum degree of -0.08 MPa to -0.1 MPa. The equipment shall be equipped with accurate vacuum control system to ensure the vacuum degree of each bottle of product is stable and consistent.

Material of equipment also needs attention. Since the sauce product is corrosive, all the parts in contact with the product shall be made of food grade 304 stainless steel, complying with food safety standards. In particular, the parts that directly contact the product, such as screwing head and conveyor belt, shall be strictly inspected.

The ease of operation cannot be ignored. Modern vacuum cap screwing machine mostly adopts PLC control system, equipped with touch screen operation interface, and the parameter setting is intuitive and convenient. Some models also have fault self-diagnosis function, which can greatly reduce downtime.

For maintenance, the equipment shall be reasonably designed for daily cleaning and maintenance. Key components, such as vacuum pump and transmission system, shall be easy to be maintained and equipped with automatic lubrication system to extend the service life of equipment.

Safety performance is also indispensable. The equipment shall be equipped with perfect safety protection devices, including emergency stop button, protective cover, etc., to ensure the safety of operators. The electrical system shall comply with relevant safety standards to prevent electric leakage and other accidents.

In practical application, the vacuum cap screwing machine for rice sauce and mixed sauce can not only improve the production efficiency, but also significantly improve the product quality. Vacuum packaging can prevent the product from oxidative deterioration and maintain the original flavor and nutrients. At the same time, packaging under vacuum can avoid leakage during transportation and improve product image.

With the development of food industry, the vacuum cap screwing machine technology is also constantly innovating. Intelligence, flexibility, energy conservation and environmental protection have become the main direction of equipment development. In the future, intelligent cap screwing machine with Internet of Things function will be able to realize remote monitoring and data analysis, providing more value-added services for manufacturers.
