吨包抽真空定型、脱气、计量充填是一个综合性的包装过程，通常应用于粉末、颗粒状物料的大包装，如化工原料、食品添加剂、矿物粉等。这个过程结合了抽真空、脱气、计量和充填等多个步骤，以确保包装物的质量和安全性。以下是对该过程的详细解析：

一、吨包抽真空定型

目的：

• 去除包装内的空气，防止物料氧化变质。

• 提高物料的堆积密度，减少包装体积，便于运输和储存。

• 保持物料的干燥性，防止受潮结块。

过程：

• 将吨包（集装袋）放置在抽真空设备上。

• 启动抽真空系统，通过真空泵将包装内的空气抽出。

• 根据需要，对包装进行热封或机械封口，以保持真空状态。

二、脱气

目的：

• 进一步去除物料中的气体，特别是溶解在物料中的气体或挥发性成分。

• 提高物料的稳定性和纯度。

过程：

• 在计量充填前，通过脱气设备对物料进行脱气处理。

• 脱气方法可能包括真空脱气、氮气置换等。

三、计量充填

目的：

• 精确控制包装内物料的重量或体积，满足客户需求。

• 提高包装效率和准确性。

过程：

• 使用计量设备（如称重传感器、流量计等）对物料进行精确计量。

• 将计量好的物料充填到吨包中。

• 充填过程中可能需要根据物料的特性调整充填速度和方式，以确保充填均匀。

四、综合应用

在实际应用中，吨包抽真空定型、脱气、计量充填通常是一个连续的过程，由专门的包装设备或生产线完成。这些设备通常具备高度自动化和智能化的特点，能够自动完成从物料输送、计量、充填到抽真空、封口等一系列操作。

五、注意事项

• 在进行吨包抽真空定型、脱气、计量充填时，需要确保设备处于良好的工作状态，并定期进行维护和保养。

• 根据物料的特性和包装要求选择合适的包装材料和封口方式。

• 严格遵守安全操作规程，确保操作人员的安全。

综上所述，吨包抽真空定型、脱气、计量充填是一个复杂而重要的包装过程，对于提高物料的质量和安全性具有重要意义。

Vacuum setting, degassing, metering and filling is a comprehensive packaging process, which is usually applied to the large packaging of powder and granular materials, such as chemical raw materials, food additives, mineral powders, etc. This process combines multiple steps such as vacuuming, degassing, metering and filling to ensure the quality and safety of the packaging. Here's a detailed breakdown of the process:

1. Tons of bags are vacuumed and shaped

Objective:

Remove the air inside the package to prevent oxidation and deterioration of the material.

Improve the bulk density of the material, reduce the packaging volume, and facilitate transportation and storage.

Maintain the dryness of the material and prevent agglomeration by moisture.

Process:

The big bags (FIBCs) are placed on the vacuum pumping equipment.

The vacuum extraction system is activated to extract the air from the package through a vacuum pump.

As needed, the package is heat-sealed or mechanically sealed to maintain a vacuum.

2. Degassing

Objective:

Further removal of gases from the material, especially gases or volatile components dissolved in the material.

Improve the stability and purity of the material.

Process:

Before metering and filling, the material is degassed by degassing equipment.

Degassing methods may include vacuum degassing, nitrogen displacement, etc.

3. Metering and filling

Objective:

Precise control of the weight or volume of the material inside the package to meet customer needs.

Improve packaging efficiency and accuracy.

Process:

Use metering equipment such as load cells, flow meters, etc. to accurately measure materials.

Fill the metered material into the ton bag.

During the filling process, it may be necessary to adjust the filling speed and method according to the characteristics of the material to ensure uniform filling.

Fourth, comprehensive application

In practical applications, the vacuuming, degassing, and metering and filling of ton bags are usually a continuous process, which is completed by special packaging equipment or production lines. These devices are usually highly automated and intelligent, and can automatically complete a series of operations from material handling, metering, filling to vacuuming and sealing.

5. Precautions

When carrying out vacuum setting, degassing, metering and filling of ton bags, it is necessary to ensure that the equipment is in good working condition, and regular maintenance and maintenance are carried out.

According to the characteristics of the material and the packaging requirements, select the appropriate packaging material and sealing method.

Strictly abide by the safety operation procedures to ensure the safety of operators.

To sum up, the vacuuming, degassing, and metering and filling of ton bags is a complex and important packaging process, which is of great significance for improving the quality and safety of materials.
