Discussion on the use of air knife and system
For many engineering technicians or factory equipment technical transformation department leaders, some people hesitate to consider whether to use air knife or air knife system when they learn that their colleagues or leaders require energy saving and consumption reduction technical transformation requirements. In fact, because the DEREIKE air knife system is used for drying, dust removal, drying, coating, and cutting water, the use and practicality are very good. Therefore, the suggestions that need to be considered when implementing air knife drying technology transformation are:
1. Air knife- There’s no mechanical moving parts, which means it is maintenance-free.
2. Applicability—The drying device (air knife system) must first be applicable to specific materials and meet the basic requirements for material drying, including the ability to handle materials (feeding, conveying, fluidization, dispersion) , Heat transfer, discharge, etc.), and can meet the basic requirements of processing capacity, dehydration capacity, product quality, etc.
3. The drying rate is high-only in terms of the drying rate, the material is highly dispersed in the hot air during air knife convective drying, the critical moisture content is low, the drying speed is fast, and the same is convective drying, and the critical moisture content is different in different drying methods Different, so the drying rate is also different.
4. Low energy consumption----Different drying (air knife drying) methods have different energy consumption indicators. The thermal efficiency of general conductive drying can theoretically reach 100%, while convection drying can only be about 70%.
5. Saving investment——The (air knife) drying device that completes the same function sometimes differs greatly in cost, so choose the lower one.
6. Low operating costs---operating costs such as equipment depreciation, energy consumption, labor costs, maintenance costs, spare parts costs should be as low as possible.
7. Air knife is the preferred drying device with simple structure, sufficient supply of spare parts, high reliability and long life.
8. It meets environmental protection requirements, with good working conditions and high safety.
9. It is best to make a drying experiment of the material before selecting the model. In-depth understanding of the drying device (advantages and disadvantages) that similar materials have been used is often helpful for proper model selection.
10. Do not rely on past experience, pay attention to absorbing new technologies, and listen to the opinions of experts from professional air knife manufacturers.
