Those skilled in the art will appreciate that, in accordance with the freeze-dried tray rack shown in fig. 19, the rectangular frame 36 intermediate the side brackets 56 thereof can also receive and lock the respective trays as previously described.
According to the freeze-dried material conveying system of the invention, when the system is in operation, a material tray 38 carrying material to be processed moves forwards, for example, from the feeding end of the material tray conveying device 1 to the position above a driving plate 10 integrally arranged with a first guide plate 7 on the material tray feeding device 4 through the driving of a roller 103, and claws 8 positioned at two sides of the driving plate are just inserted into a first gap 102 between adjacent rollers and can support the bottom of the material tray. The first driving mechanism 9 of the tray feeding device 4 lifts the first guide plate integrally provided with the driving plate to a height corresponding to the level of the tray frame 2, then the second driving mechanism 13 transfers the tray 38 transferred onto the driving plate onto the freeze-dried tray frame 2, and locks the tray in the tray frame by using the locking blocks on the tray and the locking pins on the tray frame baffle 39, and adjacent trays can also be mutually locked by the respective locking blocks and the locking pins, thereby avoiding falling of the tray caused by shaking generated by the tray frame in the moving process of the tray frame.
The specific embodiments described above are merely illustrative of the spirit of the invention. Those skilled in the art to which the invention pertains will appreciate that various modifications and additions may be made to the described embodiments or substitutions in a similar manner, but these variations and modifications are within the spirit of the invention or the scope of the invention as defined in the accompanying claims.
