That is, when the container B conveyed along the conveyor 200 is simultaneously injected into the inlet 401 of the alignment guider 400, the container B is inserted into the inlet 401 of the alignment guider 400, The supply of the fuel is slowed or stopped. Therefore, the container buffer means 500 can not be introduced into the alignment guider 400, but the container B is separately rotated and fed to the inlet of the alignment guider 400, So that it can be sequentially injected into the entrance 401 of the guider.

5 and 6, the container buffer means 500 is rotatably installed on the rotating shaft 511a of the decelerating motor 511, which is constituted by the front side of the conveyor 200 The container B which is filled at the inlet of the aligning guider 400 flows into the aligning guider 400 and the container B which has been introduced is rotated and then moved back to the inlet 401 of the aligning guider 400, And the rotating disk 510 is configured to be re-introduced into the rotating disk 510.

Further, as shown in FIG. 7, It is preferable to control the rotation speed of the deceleration motor 511 to be controlled. That is, the sensor S is configured to control the rotation speed of the deceleration motor 511 by sensing the state of the container B supplied to the inlet side of the alignment guider 400. [ Accordingly, the sensor S rapidly rotates the deceleration motor 511 when the amount of the container B supplied along the conveyor 200 is increased so that the container B at the inlet 401 of the alignment guider 400 If the amount of the container B supplied along the conveyor 200 is reduced, the speed reduction motor 511 is slowly rotated so that the container B conveyed along the conveyor 200 is rotated by the alignment guider 400 To the inlet 401 of the apparatus.

8, the container B supplied from the container supply unit 100 is conveyed along the conveyor 200 to the drying chamber 100 side. At this time, the container B conveyed to the drying chamber 100 side along the conveyor 200 is first guided through the conveying guider 300. The container randomly transferred along the conveyor 200 through the conveying guide 300 is guided along the inclined guide plate 430 of the aligning guider 400 so that the forward alignment guide plate 410 and the rear guide plate 420 into the inlet 401, one at a time.

Therefore, the containers B injected between the forward alignment guide plate 410 and the rear guide plate 420 are conveyed to the front of the drying chamber 100 while being arranged in a line. At this time, the container B is not introduced into the alignment guider 400 and the container B loaded at the inlet 401 of the alignment guider flows into the rotary disk 510 through the entrance 521 of the circular guide plate, And is discharged to the entrance 521 while being guided along the circular guide plate 520. [ Thus, since the container B loaded at the inlet 401 of the sorting guider is rotated with time through the container buffer means 500 and is then configured to re-enter the inlet 401 of the sorting guider again, So that the container B can be sequentially injected at the entrance 401 of the guider without cumbersomeness.

The containers B transferred in a line to the drying chamber 100 side along the conveyor 200 through the alignment guider 400 are sequentially conveyed by the container introducing means 120 installed in front of the drying chamber 100 And is stacked in the back-and-forth direction by a shelf inside the drying chamber 100. [

As such, the freeze dryer according to the present invention is characterized in that when the container supplied from the container supply portion is supplied to the front of the drying chamber along the conveyor, the container which is loaded at the inlet of the alignment guider is rotated with time through the container buffer means, It is possible to smoothly carry out the operation of feeding the containers in a line to the drying chamber along the conveyor in a smooth manner and thus the productivity can be improved .
