In the tunnel washer system, a tumble dryer has a great impact on the whole tunnel washer system’s efficiency. The drying speed of a tumble dryer directly determines the time of the whole laundry process. If the tumble dryers’ efficiency is low, the drying time will be prolonged, and then the production circle of the tunnel washer system will be prolonged. For example, it could originally take an hour or less to wash and dry a batch of linen, but due to the slow drying speed of the dryer, it may take an hour and a half or even longer, which greatly reduces the system’s processing capacity per unit time.
Firstly, the efficiency of the tumble dryers is closely related to their method of heating. Currently, there are steam-heated tumble dryers, thermal oil-heated tumble dryers, and direct-fired tumble dryers on the market. Comparatively, direct-fired tumble dryers and thermal oil-heated dryers have higher efficiency than steam-heated tumble dryers.
The efficiency of the dryers is also deeply affected by external factors. Taking the steam-heated tumble dryer as an example, it is closely related to the steam pressure, pressure stability, steam saturation quality, pipe length, pipe insulation measures, linen material, and moisture content.
Regardless of the type of heating tumble dryer you choose, aside from the impact of these external factors on tumble dryer efficiency, the design of the tumble dryer itself also has a significant impact on its efficiency and energy consumption, such as the dryer’s air duct structure design, insulation measures design, water delivery system design, lint cleaning design, hot air recycling design, etc. In the following article, we will describe in detail the impact of tumble dryer design on efficiency.
