In previous articles, we’ve mentioned that in tunnel washer systems, the consumption of steam relies on the water consumption when washing, the dehydration rates of water extraction presses, and the energy consumption of tumble dryers. Today, let’s dive into their connections in detail.
The Water Consumption of a Tunnel Washer Washing 1kg of Linen
The core of water consumption is water recycling. The recycled water is not cold. Recycling it can reduce the steam required for heating. However, the design of recycled water must be reasonable. If the design of recycled water is unreasonable, the actual effect will not be obvious despite it can save some water and steam compared with industrial washing machines. In addition, it is necessary to understand whether it has a lint filtration system. If the lint filtration system is not well designed, the recycled water may contaminate the linens again.
The Dehydration Rates of the Water Extraction Press
If the dehydration rate of the water extraction press is not high, then the moisture content of bed sheets, quilt covers, and towels will be high, which will have a bad effect on the speed of the ironing line. In this condition, making sure the linens are handled on time requires more ironing equipment and more employees. Also, if the moisture content of towels is high, it will take longer time, more steam, and more tumble dryers to dry those towels to ensure a timely supply of linens.
The Steam Consumption, Drying Time, and Energy Consumption of a Tumble Dryer Drying 1 kg of Water
Take 120kg tumble dryers for example. When drying towels of the same moisture content, some tumble dryers only use less than 25 minutes while some 120 kg tumble dryers require 40 minutes. In this case, their gap after a month will be huge.
If any one of all three designs above has some problems, the efficiency and energy consumption of overall tunnel washer systems will be badly affected. In the following articles, we will analyze these three designs one by one.
