食品行业用气力输送设备有哪些特点？

What are the characteristics of pneumatic conveying equipment in food industry?

气力输送概念：

Pneumatic conveying concept:

气力输送是运用风机或其他动力设备，使管道内形成一定速度的气流，将散装物料沿一定的管路从一处输送到另一处，称为气力输送或气流输送。

Pneumatic conveying is the use of fans or other power equipment to form a certain speed of air flow in the pipeline and transport bulk materials from one place to another along a certain pipeline, which is called pneumatic conveying or pneumatic conveying.

食品行业主要粉体物料有：

The main powder materials in food industry are as follows:

面粉、淀粉、巧克力粉、果胶、纯碱、小苏打、食盐、味精、奶粉等等。在食品厂生产中，目前广泛采用的是使散装物料呈悬浮状态的输送方式或动态输送，按其工作原理可分为：吸送式、压送式、混合式和循环式。

Flour, starch, chocolate powder, pectin, soda, sodium bicarbonate, salt, monosodium glutamate, milk powder and so on. In the production of food factory, it is widely used to make bulk materials in suspension or dynamic transportation. According to its working principle, it can be divided into suction, pressure, mixing and circulation.

用气力输送食品物料具有以下特点：

Pneumatic conveying of food materials has the following characteristics:

优点：

advantage:

1、物料在管道中的输送，减少场所粉尘污染，工作环境卫生得到改善，降低了物料输送过程中的损耗。

1. The transportation of materials in the pipeline can reduce the dust pollution, improve the working environment and reduce the loss in the process of material transportation.

2、输送装置结构简单，无回程系统，管理方便、易于实现自动化操作。

2. The conveying device has the advantages of simple structure, no return system, convenient management and easy automatic operation.

3、输送路线容易选择，布置灵活，占地面积小。

3. The transportation route is easy to choose, the layout is flexible, and the floor area is small.

4、输送生产效率高，降低物料的装卸成本。

4. High efficiency of conveying production, reduce the loading and unloading costs of materials.

5、在输送过程中可以同其他工艺结合起来，进行干燥、冷却、分选及混合等操作。

5. In the transportation process, it can be combined with other processes for drying, cooling, sorting and mixing.

缺点：

Disadvantages:

1、动力消耗大，噪声高。近年来改进方案，引用磁动力原理，采用摩擦小噪音小的磁动力风机。

1. High power consumption and high noise. In recent years, the improved scheme uses the principle of magnetic force, and adopts the magnetic force fan with small friction and low noise.

2、管道及物料接触的构件易磨损。近年来应用陶瓷耐磨管道、弯头。也在不断研究新技术和解决问题的方案。

2. The components in contact with pipes and materials are easy to wear. In recent years, ceramic wear-resistant pipes and elbows have been used. We are also constantly studying new technologies and solutions to problems.

3、对输送物料有一定限制，不以输送、易于成块、粘结和已破碎的物料。对于比较特殊的物料，我们不断改进传统设备，传统工艺，要就更尖 端技术，不断扩大物料范围。

3. There are certain restrictions on the transportation of materials, not to transport, easy to block, bond and broken materials. For more special materials, we continue to improve the traditional equipment, traditional technology, to more sophisticated technology, and constantly expand the scope of materials.

食品物料应用粉体气力输送系统，是食品产业清洁生产的重要过程。可以有效解决近年来对于食品安全的忧患。

The application of powder pneumatic conveying system for food materials is an important process of clean production in food industry. It can effectively solve the food safety problems in recent years.
