It is suggested that the food industry choose 304 stainless steel or ABS engineering plastic hand dryer.
2. Weight: It is necessary to consider whether the installation location and materials can bear the weight of the automatic hand dryer. For example, the weight of cement brick walls can generally be ignored, but the bearing capacity of materials such as color steel plates and gypsum boards should be considered.
3, color: hand dryers are rich in color, usually white and stainless steel are the best choice for food factories. If environmental factors must be considered, stainless steel paint is also a good choice.
4. Starting principle: manual timing switch, infrared induction, light blocking induction mode.
The latter two methods are non-contact induction, so it is suggested that food factories adopt hand dryers with the latter two startup methods, which can effectively avoid cross-infection.
5. Installation method: bracket installation, wall-mounted installation and direct desktop placement.
In most cases, it is recommended to install it on the wall, which is stable and durable.
6. Working noise: try to be as small as possible under the condition of meeting the hand drying speed.
7. Operating power:: The lower the better, under the condition of meeting the dry hand speed and maintaining comfort.
8. Hand drying time: the shorter the better, the better within 10 second (basically the same as using toilet paper).
9. Air temperature: Hand dryers with air temperature between 35 degrees Celsius and 45 degrees Celsius will neither waste electricity nor feel uncomfortable.
