A towel dryer is one of the towel cleaning devices that is typically used to remove moisture from towels and other linens after the water has been eluted.
1, the size of the towel dryer heater power
The greater the heat power of the heater, the more heat energy is generated per unit time, the easier it is to dry the clothes. The most common heating methods for the dryer are electric heating, steam heating, gas heating, and the heat power is in unit time. How much heat is generated to measure the electric power of the electric heater, and the heat generated by the gas heater in the unit time is determined after the burner size and the gas type are determined. Electric heaters can generate 860 calories per kWh on average, and gas-fired dryers can produce 8600 calories from 1 cubic meter of natural gas. At present, the market is about 0.8 yuan, and one cubic meter of gas is 3 to 4 yuan. From the perspective of heat, the use of gas dryers is definitely cheaper than electric heating and steam heating. The heat generated by the steam heater is more complicated, in addition to the steam heater tube and the heat sink surface, and also has a great relationship with the steam pressure and the air volume and temperature flowing through the heater. If the steam pressure is high, the temperature of the surface of the steam heater is high, and the amount of heat generated is large, and vice versa. Therefore, whether it is electric heating, steam heating or gas heating, the hot energy generated per unit time is higher as the heat of the dryer fan is the same. When the heat power is high, the temperature of the air is high, which satisfies the three favorable conditions of rapid evaporation of water, and the higher the temperature, the more favorable the conditions for drying.
2. The load ratio and rotation speed of the towel dryer drum
The industry standard stipulates that the dryer load ratio is greater than 1:18. Under normal circumstances, the load ratio is 1:20 or higher, but in foreign or domestic garment washing industry, due to the special use of 1:25 and 1:30. It can be affirmed that under certain conditions, the same amount of clothes are dried. If the volume of the drum is larger, the drying speed is increased. In addition, the rotation speed of the drum will directly affect the uniformity of the laundry in the drum during the drying process. Sexuality, the more uniform the clothes are thrown under the premise of determining the volume of the drum, which means that the larger the exposed surface area of the water in the clothes, the more favorable the evaporation of moisture in the clothes. The excessively high and low speeds will affect the clothes. The uniformity, the speed is too high, the clothes will stick to the roller; the rotation speed is too low, the clothes will roll, which will affect the drying speed and heat utilization.
3, the towel dryer to dry the load of clothing
The load of clothes directly affects the moisture content of the clothes, and it also affects the uniformity of the clothes thrown in the drum. The clothes are loaded less, the moisture is less, and the drying is surely fast; on the other hand, the clothes are loaded less and dried. During the process, the surface area of the moisture in the clothes is large, and it is more favorable for increasing the drying speed. However, if the laundry load is too small, although the drying speed is fast, the heat energy loss rate is high. Therefore, considering the comprehensive energy consumption and drying speed, the laundry load of the dryer is generally reasonable from 50% to 80% of the approved drying capacity.
4. What is the variety and water content of the towel dryer?
The greater the moisture content of the laundry, the more heat is required to evaporate the water in the laundry. Due to the different textures or different loadings of the fabrics, the moisture content of the fabrics is still very different after dehydration by the same type of industrial washing machine or dewatering machine. The moisture content of towels and clothes is very different, so the time to dry the towels and the time to dry the clothes are very different. Therefore, in order to shorten the drying time, it is particularly important to choose a washing machine with a high dehydration value, because the cost of evaporating one kilogram of water in the laundry is much greater than the one kilogram of water from the washing machine.
