[0002] The basic principle of freeze-drying is based on the three states of water. Water exists in solid, liquid, and gaseous states, all of which can both convert into each other and coexist. When water is at its triple point (temperature 0.01°C, vapor pressure 610.5 Pa), water, ice, and water vapor can coexist and maintain equilibrium. Under high vacuum conditions, the principle of sublimation is utilized to remove moisture from pre-frozen materials directly from the ice into water vapor without melting, thus achieving the purpose of freeze-drying.

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] As attached Figure 1 To the attached Figure 4 As shown:

[0026] Embodiment 1: The present invention provides a novel feeding and discharging device for a food freeze dryer, comprising:

[0027] A freeze dryer body 1 is provided with a transmission mechanism 8 installed on both sides of the freeze dryer body 1. The transmission mechanism 8 is connected to the inner wall of the freeze dryer body 1 through a bearing seat 9. A traction chain 2 is installed on the periphery of the transmission mechanism 8. The ends of the traction chain 2 that are away from each other are respectively connected to a plurality of first hanging ears 3 and second hanging ears 4;

[0028] Guide rails 6 are installed at both ends of the freeze dryer body 1, and there is an inclined surface between the guide rails 6 at the entrance of the freeze dryer body 1;

[0029] A quick-connect latch mechanism 5 is installed on one end of the first hanging ear 3 and the second hanging ear 4 close to the guide rail 6;

[0030] The quick-connect latch mechanism 5 includes a spring 502 installed at one end of the first hanging ear 3 and the second hanging ear 4 close to the guide rail 6, the other end of the spring 502 is connected to a roller 501 in contact with the guide rail 6, and the end of the roller 501 away from the guide rail 6 is connected to a latch 503, and the latch 503 passes through the first hanging ear 3 and the second hanging ear 4 respectively.

[0031] The existing freeze-drying trolley has two protrusions at the bottom, with sockets at both ends of the protrusions. The distance between two adjacent pins 503 is the same as the distance between the sockets on the two adjacent protrusions.

[0032] As can be seen from the above, the door of the freeze dryer body 1 is opened, and the freeze-drying trolley carrying the freeze-dried products is pushed to the designated position in front of the door of the freeze dryer body 1 by the dedicated AGV trolley. The protrusion at the bottom of the freeze-drying trolley is inserted between the traction chain 2. The position of the socket on the protrusion is the same as the position of the latch 503. After the driving mechanism 11 is energized, the traction chain 2 is driven to rotate through the transmission mechanism 8. During the rotation of the traction chain 2, the quick-connect latch mechanism 5 is driven to move at the same time. The roller 501 pushes the latch 503 through the first hanging ear 3 and the second hanging ear 4 into the socket of the protrusion at the bottom of the freeze-drying trolley under the extrusion of the inclined surface of the guide rail 6. At this time, the spring 502 on the latch 503 is in a squeezed state, thereby realizing automatic docking. After the docking is completed, the freeze-drying trolley enters the cavity of the freeze dryer body 1 under the traction of the traction chain 2;

[0033] When the processed freeze-drying trolley needs to be guided out from the interior of the freeze dryer body 1, the driving mechanism 11 drives the transmission mechanism 8 to rotate in the opposite direction. During the reverse rotation of the transmission mechanism 8, the traction chain 2 drives the freeze-drying trolley inside the freeze dryer body 1 to move through the quick-connect latch mechanism 5, so that the freeze-drying trolley moves to the front end of the cavity of the freeze dryer body 1. When the roller 501 moves back to the inclined surface on the guide rail 6, the spring 502, which has been in an extruded state, opens, causing the roller 501 to roll along the inclined surface. At the same time, the latch 503 follows the movement of the roller 501 and is pulled out from the socket of the protrusion at the bottom of the freeze-drying trolley, realizing automatic disconnection and stopping the traction of the freeze-drying trolley. The disconnected freeze-drying trolley is now in a position where the special AGV trolley can receive traction. The special AGV trolley is controlled by the scheduling system to move the freeze-drying trolley.

[0034] By installing structures such as a traction chain 2, a quick-connect pin mechanism 5 and a guide rail 6, the freeze-drying trolley can be automatically connected to and disconnected from the freeze-drying trolley during use. After automatic connection, the freeze-drying trolley can be automatically towed into the cavity of the freeze-drying machine body 1 under the drive of the traction chain 2. When unloading, the freeze-drying trolley can be towed to the front end of the cavity of the freeze-drying machine body 1 by rotating the traction chain 2 in the opposite direction, and the connection between the quick-connect pin mechanism 5 and the freeze-drying trolley can be automatically disconnected at the same time, so that the freeze-drying trolley can be moved out from the inside of the freeze-drying machine body 1 using a special AGV trolley, saving manpower and improving processing efficiency.

[0035] Specifically, regarding the guide rail 6 , the distance between the inclined surfaces of the guide rail 6 is the same as the distance between two adjacent first hanging ears 3 .

[0036] As can be seen from the above, during the movement of the first hanging ear 3 and the second hanging ear 4, the quick-connect latch mechanism 5 will move along the inclined surface on the guide rail 6. After the roller 501 contacts the inclined surface, the latch 503 begins to move toward the socket position on the protrusion of the freeze-drying trolley until the roller 501 moves to the top of the inclined surface and the latch 503 is completely inserted into the socket on the protrusion.

[0037] Specifically, regarding the above-mentioned transmission mechanism 8 and driving mechanism 11, the transmission mechanism 8 includes a transmission shaft 801 and a chain gear 802. The transmission shaft 801 is rotatably mounted inside the bearing seat 9, and the rear end of the transmission shaft 801 passes through the bearing seat 9 and extends out of the freeze dryer body 1;

[0038] The chain gear 802 is installed on the periphery of the transmission shaft 801, and the chain gear 802 and the traction chain 2 are meshed with each other;

[0039] The output end of the driving mechanism 11 is connected to the transmission shaft 801 via a coupling 12 .

[0040] As can be seen from the above, during the operation of the driving mechanism 11, its output end drives the transmission shaft 801 to rotate through the coupling 12. During the rotation of the transmission shaft 801, the chain gear 802 is driven at the same time, thereby driving the traction chain 2 to rotate and move;

[0041] The coupling 12 can be used to firmly connect the output end of the driving mechanism 11 and the transmission shaft 801 so that they rotate together and transmit motion and torque to ensure that the two shafts cannot be separated when the machine is running.

[0042] Example 2: This example is basically the same as the previous example, except that a plurality of brackets 7 are mounted on ends of the guide rails 6 that are away from each other, and the bottoms of the brackets 7 are connected to the inner wall of the freeze dryer body 1;

[0043] Several bases 10 are installed at the bottom of the freeze dryer body 1 , and a base connected to the base 10 is installed at the bottom of the driving mechanism 11 .

[0044] The bracket 7 is located between the transmission mechanisms 8 .

[0045] As can be seen from the above, the guide rail 6 can be supported by the bracket 7 to prevent the guide rail 6 from being displaced inside the freeze dryer body 1, so that the movement of the quick-connect latch mechanism 5 is more stable. The freeze dryer body 1 can be supported by the base 10 during use to maintain a certain height between the bottom of the freeze dryer body 1 and the ground to meet the needs of cooperating with the AGV trolley to dock the freeze-drying trolley carrying the freeze-dried products.
