Fruit Modified Atmosphere Packaging Machine

Fruit Modified Atmosphere Packaging MachineCore technical principles

1. Gas displacement and mixing
The modified atmosphere packaging machine is filled with a proportionally mixed preservation gas (usually nitrogen) after vacuumingN₂Carbon dioxideCO₂OxygenO₂Replace the air inside the packaging with two or three of them. among which
CO₂Inhibition of bacterial and fungal reproduction;
N₂As an inert gas filling to prevent oxidation;
O₂Used to maintain the respiration of fresh food or inhibit anaerobic bacteria.
The accuracy of gas mixing is usually controlled within±1%Within, the replacement rate can reach95%The above.

2. Preservation mechanism
Delaying food spoilage by reducing cellular aerobic respiration rate (such as in vegetables) or inhibiting microbial activity (such as in cooked food). Some equipment combines vacuum pre cooling technology to quickly cool down before packaging0-4℃Further extend the shelf life.

Fruit Modified Atmosphere Packaging MachineEquipment type characteristicsWith advantages

Extend shelf life and reduce losses

1. Inhibit microbial growth
By replacing the oxygen inside the packaging and filling itCO₂TheN₂Wait for gas, inhibit aerobic bacteria and mold growth, and extend shelf life3-10Twice. For example, fresh meat can have a refrigerated shelf life of up to7-30Tian, fruits and vegetables can be extended to10-30Oh my god.

2. Slow down oxidation and respiration
Inert gases (such asN₂）Reduce oxidative reactions, slow down respiration and metabolism of fruits and vegetables in low oxygen environments, and maintain freshness.

Maintain food quality and taste

1. original flavor
No need for high-temperature sterilization or chemical preservatives, avoiding loss of food nutrients and changes in taste. For example, cooked food products are sold throughCO₂andN₂Mixed gas preservation can maintain the original color and flavor.

2. Prevent physical damage
Sealed packaging reduces compression deformation during transportation and maintains the integrity of food appearance.

Safety and Environmental Protection

1. Reduce dependence on additives
Modified atmosphere preservation technology replaces some preservatives, which is in line with the trend of healthy consumption.

2. Reduce pollution risk
Sealed design prevents external pollutants from entering and avoids cross infection.

Efficient production and flexibility

1. High degree of automation
The fully automatic model realizes the automation of the entire process of vacuum pumping, inflation, and sealing, with an efficiency of6-8time/Minutes, reduce labor costs.

2. Adapt to diverse needs
The gas ratio can be adjusted according to the type of food, such as high oxygen preservation for meat and high oxygen preservation for cooked foodCO₂Antibacterial), supporting customized packaging solutions.
