Automatic vacuum packaging machine: a tool to improve the efficiency of food and industrial product packaging

　　In the modern packaging industry, vacuum packaging technology has become an important means to extend the shelf life of food and ensure product quality. The traditional manual or semi-automatic vacuum packaging method of low efficiency, packaging consistency is poor, can not meet the needs of mass production. With the development of automation technology, automatic vacuum packaging machine came into being, with high efficiency, standardization, saving labor costs and other advantages, widely used in food, medicine, electronics, chemical industry, hardware and other industries, become an indispensable equipment in the packaging line.

　　First, the definition and working principle of automatic vacuum packaging machine

　　1.Definition

　　Automatic vacuum packaging machine is a kind of equipment by automatically extracting the air inside the bag and sealing the seal. Its role is to:

　　Extend the shelf life: by extracting the air inside the bag, reduce the oxygen content, inhibit microbial growth, thereby extending the shelf life of food or other products.

　　Anti-moisture and anti-oxidation: vacuum packaging of electronic components, precision instruments, etc., effectively preventing oxidation, corrosion and moisture.

　　Saving volume and convenient storage and transportation: the volume of products after vacuum packaging is smaller, which is convenient for storage and transportation.

　　2.Working Principle

　　The workflow of automatic vacuum packaging machine mainly includes the following steps:

　　1. Automatic loading and positioning: the products are automatically fed into the packaging machine by conveyor belt or robot.

　　2. Vacuum extraction and inflation (optional): the equipment automatically extracts the air inside the bag and can be filled with nitrogen, carbon dioxide or mixed gases according to the demand to prevent the food from oxidizing.

　　3. Sealing & Cooling: The bags are sealed by heating device and cooled and shaped to ensure the sealing.

　　4. Automatic collecting and conveying: after the packaging is completed, the products are automatically output through the conveyor belt to enter the next process.

　　Second, the core advantages of automatic vacuum packaging machine

　　1. Improve production efficiency, save labor costs: automatic vacuum packaging machine automatic operation, can realize continuous, high-speed packaging, significantly improve production efficiency. Single machine can complete thousands of bags of vacuum packaging per hour, far beyond the manual or semi-automatic packaging speed. Reduce manual operation and labor intensity, saving labor costs.

　　2. Extend shelf life, maintain product freshness: vacuum packaging can block oxygen, inhibit bacterial growth, effectively extend the shelf life of food. For meat, aquatic products, fruits and vegetables, recreational food, etc. has a significant preservation effect. For electronic components, pharmaceuticals, metal parts, etc. can prevent moisture and rust, to maintain product quality.

　　3. Consistent packaging effect and stronger sealing: automatic equipment ensures sealing consistency and avoids air leakage through precise control of temperature and time. Stable packaging quality, neat and beautiful appearance of the finished product, conducive to the brand image of the product.

　　4. Easy operation and intelligent control: equipped with PLC control system and touch screen operation interface, the parameters can be set freely and the operation is convenient. With memory function and automatic adjustment ability, it can realize the switching of multi-species packaging.

　　5. Energy saving and environmental protection, reduce material waste: vacuum packaging machine can accurately control the amount of packaging film, reduce waste. High sealing efficiency, reduce the failure rate, reduce material loss.

　　Third, the application of automatic vacuum packaging machine

　　1. Food industry: widely used in fresh meat, seafood and aquatic products, pickled food, frozen food, fruits and vegetables and leisure food vacuum packaging. Vacuum packaging can effectively prevent food oxidation, corruption and crosstalk, prolong shelf life and maintain the original flavor. Part of the equipment to support nitrogen or mixed gas packaging, for potato chips and other puffed food.

　　2. Pharmaceutical and health care industry: vacuum packaging for pharmaceutical reagents, medical devices, pharmaceutical raw materials, to prevent moisture and oxidation. Medical devices (such as syringes, catheters, gauze) vacuum packaging to ensure sterility.

　　3. Electronics and semiconductor industry: vacuum packaging for circuit boards, chips, precision instruments, electronic components, moisture and oxidation. Protect electronic products from the external environment, prolong service life.

　　4. Hardware and industrial parts industry: vacuum packaging for metal parts, bearings, fasteners, to prevent oxidation and rust. Improve the storage stability and appearance of products.

　　5. Daily chemical and chemical industry: vacuum packaging for cosmetics, chemical reagents, paints, chemical raw materials, etc. to prevent volatilization and deterioration. Effectively improve product shelf life and transportation safety.

　　Fourth, the future development trend of automatic vacuum packaging machine

　　1. Intelligent and digital control: future equipment will be combined with the Internet of Things and big data to achieve remote monitoring and intelligent control. Through data collection and analysis, optimize packaging parameters, improve packaging quality and efficiency.

　　2. Modular and flexible production: automatic vacuum packaging machine will be modular and flexible design development, can quickly adapt to different packaging specifications and materials. Support the rapid replacement of molds and bag specifications to meet the needs of multi-species, small batch production.

　　3. Energy saving and environmental protection and green packaging: the use of energy-saving motors and environmentally friendly materials to reduce energy consumption and environmental pollution. Use of biodegradable packaging materials to realize green packaging.

　　4. High-speed and automation integration: future equipment will be integrated with automated conveyor lines, testing equipment, palletizing robots, etc., to achieve integrated packaging and unmanned production. Further enhance the production efficiency and intelligence level.

　　Automatic vacuum packaging machine as the core equipment of modern packaging automation, with high efficiency, precision, good sealing and labor cost saving advantages, in the food, medicine, electronics, hardware and other industries play a vital role. With the rise of intelligent manufacturing, flexible production and green packaging trends, automatic vacuum packaging machine will realize more efficient, more environmentally friendly, more intelligent development in the future, bringing more competitive advantages for various industries.
