In tunnel washer systems, water extraction presses are important pieces of equipment connected to tumble dryers. The mechanical methods they adopt can reduce the moisture content of linen cakes in a short time with little energy costs, resulting in lower energy consumption for post-wash finishing in laundry factories. This not only enhances tumble dryers' efficiency but also shortens drying times, which can otherwise impact the tunnel washer systems' performance. If a CLM's heavy-duty water extraction press is set to operate at 47 bar pressure, it can achieve a 50% moisture content, which is at least 5% lower than conventional presses.
Take a laundry factory washing 30 tons of linens a day for example:
Calculated based on the ratio of towels to bed sheets being 4:6, for example, there are 12 tons of towels and 18 tons of bed sheets. Assuming the moisture content of the towel and linen cake is reduced by 5%, 0.6 tons of water can evaporate less per day during towel drying.
According to the calculation that a CLM steam-heated tumble dryer consumes 2.0 kg of steam to evaporate 1 kg of water (average level, minimum 1.67 kg), the steam energy saving is about 0.6×2.0=1.2 tons of steam.
A CLM direct-fired tumble dryer consumes 0.12m³ of gas to evaporate 1kg of water, so the gas energy saving is about 600Kg×0.12m³/KG=72m³.
This is just the energy saved by the heavy-duty water extraction presses of a CLM tunnel washer system in the towel drying process. Reducing the moisture content of sheets and quilt covers also has a great impact on the energy and efficiency of ironing equipment.
