1) start initialization operation, after the completion of initialization operation, the heating device of upper space abuts the of upper space First lid of two transverse slats, upper space is not abutted with the frame portion of upper space, and the heating device of lower space abuts lower space The second transverse slat, lower space first lid is not abutted with the frame portion of lower space;
2) side door is opened, material to be dried is placed in the frame portion of upper space and in the frame portion of lower space;
3) close side door, start the first drying process, in first drying process, upper space and lower space plus Thermal opens and abuts the second transverse slat, the first lid of upper space and lower space with frame portion is not low connects, and work as air pressure When the measured value of sensor is greater than given threshold, open vacuum pump;
4) start the second drying process, in second drying process, the heating device of upper space and lower space is opened Open and abut the first transverse slat, the second lid of upper space and lower space with frame portion is not low connects, and work as baroceptor When measured value is greater than given threshold, open vacuum pump;
5) heating device for closing upper space and lower space, cancels vacuum state, opens side door, takes out dry complete Material.
First transverse slat of material load bearing unit has in face of the side of the first lid and the second transverse slat in face of the side of the second lid There is radiating fin.First lid of the material load bearing unit and the second capping all have gasket to the side of frame portion.The frame Portion is rectangle frame portion.The section of first polished rod and the second polished rod is rectangle.The duration of first drying process Equal to the duration of the second drying process.First transverse slat and the second transverse slat have radiating fin, thus heating device and first, When two transverse slats abut, heat can be quickly transferred at the first and second lid by radiating fin to help.Sealing at first and second lid Pad can prevent gap of the material between frame portion and the first and second cover from leaking out.
The principle of the present invention is first to be dried with side of first drying process to material, after a period of time, by first Lid, frame portion and the second lid overturning 180 degree, so that the other side to material is dried, consequently facilitating the water of the other side of material Divide quickly volatilization, drying efficiency is high.Switching between first drying process and the second drying process is as shown in figure 3, first make first The sealing of cover and frame portion, then declines movable plate, and then making frame portion and the first and second lid overturning 180 degree, (overturning is by the second motor Realize), then rising movable plate makes heating device abut the first transverse slat;Then open the second cover and frame portion.Movable plate Decline makes the overturning of frame portion, the first lid and the second lid for convenience.When heating device abuts the first transverse slat or heating device supports When connecing the second transverse slat, on the one hand it can be heated, on the other hand enable to the first transverse slat and the second transverse slat more stable, keep away Exempt from unexpectedly to rotate.In addition, the opening and closing of side door, initialization operation, the execution of the first heating operation and the second heating operation are held Capable and duration setting can be completed by touch screen, execute institute again after the first heating operation of duration needed for executing certainly The second long heating operation is taken, this switching can be what controller control executed automatically, and operator only need to start to set Well just.That is switching of the step 3) to step 4), which can manually perform, also can be performed automatically.
Although the present invention is illustrated and has been described with regard to preferred embodiment, it is understood by those skilled in the art that Without departing from scope defined by the claims of the present invention, variations and modifications can be carried out to the present invention.
