Prefabricated food preservation packaging machineThe core technologies of our company revolve around three main objectives: freshness preservation, precise and efficient packaging, intelligent control, and safety assurance. At the same time, we also consider flexible production to adapt to multiple product categories. The following is a detailed analysis of each core technology:
Core technology of locking freshness and preservation
This type of technology is key to ensuring the taste and shelf life of pre made dishes. By regulating the packaging environment and optimizing the sealing process, it solves industry pain points such as oxidation deterioration and leakage.
Micro pressure gradient vacuum and modified atmosphere displacement technology: This is the mainstream freshness locking technology. On the one hand, the residual oxygen content inside the packaging is controlled below 0.8% through micro pressure gradient vacuum technology, which inhibits food oxidation and microbial growth. For example, the shelf life of pre made meat dishes can be significantly extended at room temperature after this treatment; On the other hand, with the use of a modified atmosphere displacement module, the ratio of nitrogen to carbon dioxide is intelligently matched. For example, for high moisture vegetables, 30% -60% carbon dioxide is added to suppress aerobic bacteria, while for meat, 2% -5% oxygen is retained to maintain color. This can extend the shelf life of pre made vegetables at room temperature to 180 days.
Precise low-temperature sealing technology: For pre packaged dishes such as soup and sauce that are prone to liquid leakage, the equipment can control the sealing temperature error within ± 1 ℃, while accurately regulating the sealing pressure, combined with food grade high sealing film to form dual protection. This technology can prevent air and liquid leakage at the sealing point from the root, prevent food from oxidizing and deteriorating when exposed to air, and is particularly suitable for the packaging needs of solid-liquid mixed pre made dishes.
Vacuum body packaging technology: By tightly wrapping ingredients and trays with thin film, it can not only reduce air residue inside the packaging, but also reduce the loss of juice from pre packaged dishes during freezing and transportation. For example, using this technology for pre made hotpot dishes such as beef rolls can increase the retention rate of juice after thawing by 20%, while avoiding the damage of frozen crystallization to the taste of the ingredients.
Accurate and efficient packaging technology
This type of technology focuses on improving production efficiency while ensuring packaging accuracy, adapting to large-scale production of pre packaged dishes and multi category packaging needs, and reducing labor and material losses.
AI vision and high-precision measurement feeding technology: The equipment is equipped with a 3D visual recognition system, which can automatically correct the feeding trajectory and solve the feeding deviation problem of irregular ingredients and layered packages. Paired with a dual measurement module for volume and weight, it can achieve precise feeding of solid ingredients with a weight error of<± 0.5% and liquid sauces with an error of<± 1ml. It also supports layered filling of main and side dishes, increasing the efficiency of complex meal packaging by three times.
High speed automation packaging integration technology: The equipment achieves full process automation of automatic bag retrieval, opening, filling, and sealing through high-precision mechanical claws and servo drive systems. For example, a single bag packaging machine can complete 2800 packages per hour, and a vacuum packaging machine can pack 20-50 pieces per minute, which is equivalent to the daily workload of 5-6 skilled workers. The bag opening rate and packaging qualification rate are both 99.9%.
Flexible transformation and adaptation technology: adopting modular design, it can switch between round bowls, square boxes, and irregular containers within 30 minutes, and adapt to pre made dishes of different sizes ranging from 200g to 2kg. Some models even take less than 5 minutes to change, which can meet the production needs of small batches and multiple categories, and avoid the waste of production capacity caused by frequent category switching for enterprises.
Intelligent control and security technology
This technology runs through the entire packaging process, ensuring controllable production and meeting food safety supervision and traceability requirements, reducing production risks.
PLC and MES system linkage technology: The equipment is equipped with a PLC control system, which can achieve automated connection of processes such as feeding, packaging, and sealing. At the same time, high-end models can be integrated with MES production management systems. The system collects key parameters such as vacuum degree, sealing temperature, and filling weight in real-time, and can also generate a unique traceability code. Scanning the code can view information such as packaging time and production batch, achieving full lifecycle traceability of the product.
Aseptic testing and foreign object removal technology: On the one hand, the equipment body is made of food grade 304 stainless steel material, with a protection level of IP66, which can be directly rinsed with water to avoid bacterial growth caused by food residue; On the other hand, it has built-in metal detection and X-ray foreign object screening modules, combined with an automatic defect removal device, achieving an accuracy rate of 99.99%. At the same time, the entire packaging process achieves zero manual contact, and the microbial control level is improved by 90% compared to traditional equipment.
Remote operation and intelligent warning technology: Some high-end models integrate IoT technology to support remote monitoring of device operation status. Real time monitoring of key components such as vacuum pumps and sealing parts through sensors can provide early warning of potential faults and reduce downtime for maintenance. At the same time, the sealing parameters can be automatically adjusted through infrared temperature feedback to solve the problem of packaging quality fluctuations caused by equipment aging or environmental temperature changes.
Energy saving and compatibility integration technology
Although this type of technology does not have direct preservation or packaging functions, it can reduce production costs for enterprises and meet the needs of automated production lines. For example, the application of new servo vacuum pumps can reduce power consumption by 35% and compressed air consumption by 50% compared to traditional models; The equipment can seamlessly connect upstream frying pans, cooling machines, downstream weight detection machines, and packaging robots, forming a complete automated production line. At the same time, it supports integration with RFID tag systems, further improving the traceability system of prefabricated food production and becoming the central node of the production line.
