Method for drying cashmere loose fibers through radio frequency
A radio frequency drying, cashmere fiber technology, applied in drying, method combination to dry solid materials, dry solid materials and other directions, can solve the damage to the surface state and internal structure of cashmere fibers, the difference between the dry and wet of cashmere fibers, and the drying of cashmere fibers. Uneven drying and other problems, to achieve uniform drying effect, avoid large differences in dry and wet, and accurately control the effect of moisture regain

Embodiment 1
[0013] Embodiment 1, a method for drying cashmere loose fibers using radio frequency, is characterized by comprising the following steps: Step A): dehydrating the cashmere fibers with a centrifugal dehydrator, the rotational speed of the centrifugal dehydrator is 6000 rpm, The dehydration time is between 10 minutes, and the moisture content of the cashmere fiber is uniformly controlled at 40% after dehydration. Step B): spread the dehydrated cashmere fibers on the conveying flat curtain, and feed them between the upper and lower plates of a radio frequency generator with a power of 80KVA at a speed of 18 m / h. The distance between the upper and lower plates is 400 mm, the radio frequency generator emits a radio frequency of 27.00 MHz to the cashmere fiber to dry the cashmere fiber. Step C): During the drying process, the moisture evaporated from the cashmere fibers is discharged out of the radio frequency generator through an exhaust fan. Step D): collecting and packaging the ...
Embodiment 2
[0014] Embodiment 2, a method for drying cashmere loose fibers using radio frequency, is characterized by comprising the following steps: Step A): dehydrating the cashmere fibers with a centrifugal dehydrator, the rotational speed of the centrifugal dehydrator is 7000 rpm, The dehydration time is between 15 minutes, and the moisture content of the cashmere fiber is uniformly controlled at 38% after dehydration. Step B): Lay the dehydrated cashmere fiber on the conveying flat curtain, and feed it between the upper and lower plates of a radio frequency generator with a power of 100KVA at a speed of 20 m / h. The distance between the upper and lower plates is 300 mm, the radio frequency generator emits a radio frequency of 27.12 MHz to the cashmere fiber to dry the cashmere fiber. Step C): During the drying process, the moisture evaporated from the cashmere fibers is discharged out of the radio frequency generator through an exhaust fan. Step D): collecting and packaging the dried...
Embodiment 3
[0015] Embodiment 3 A method for drying cashmere loose fibers using radio frequency, which is characterized by comprising the following steps: Step A): dehydrating the cashmere fibers with a centrifugal dehydrator, and the rotational speed of the centrifugal dehydrator is 8000 rpm , the dehydration time is 20 minutes, and the moisture content of the cashmere fiber after dehydration is uniformly controlled at 36%-. Step B): Lay the dehydrated cashmere fiber on the conveying flat curtain, and feed it between the upper and lower plates of the power 150KVA radio frequency generator at a speed of 22 meters per hour, and the distance between the upper and lower plates is 200 mm, the radio frequency generator emits a radio frequency of 27.50 MHz to the cashmere fiber to dry the cashmere fiber. Step C): During the drying process, the moisture evaporated from the cashmere fibers is discharged out of the radio frequency generator through an exhaust fan. Step D): collecting and packagin...
