Using segmented damping press belt, all materials wrapped up by pressure zone will be delivered to by segmented damping press belt to pressure pressure, such as
Fruit cornerite is 180 degree, a diameter of 800 millimeters of dehydration roll, then pressed zone effective length just has 1256 millimeters, is tradition to roll-in
Squeeze design more than 4 times.In this pressed zone, bigger closer to two pairs of rollers squeezing point pressure, material water ratio is also lower, accordingly
, the relative movement resistance inside material is also bigger, in material pressure due to material the effect of inside moving resistance and decay,
It is higher to pressure suffered by the nearer material of pressure roller, it is lower from pressure suffered by the material more remote to pressure roller, then in squeezing passage
The mechanism being pressurized gradually is inside naturally form, high-moisture percentage material is dehydrated through low pressure, and low-water-content material is dehydrated through High Voltage,
This is completely the same with dewatering process requirement, because more dry material needs higher pressure to be dehydrated, conversely, moisture content
Higher material only needs relatively low pressure to be dehydrated.In order to which pressure is squeezed in more flexible control, multiple dampings can be set to pressure
Roller, the progressive supercharging drying zone of cattle horn shape is divided into the progressive supercharging drying zone of multiple small cattle horn shapes, regulation is each as needed
The pressure in area.
