Description

Technical Field

[0001] The invention belongs to the technical field of freeze drying machines, and in particular relates to a high-efficiency freeze drying device. Background Art

[0002] The basic principle of the freeze-drying device is based on the three-state change of water. Water has solid, liquid and gaseous states. The three states can be converted into each other and can coexist. When water is at the triple point (temperature is 0.01°C, water vapor pressure is 610.5Pa), water, ice and water vapor can coexist and balance each other. Under high vacuum conditions, the sublimation principle is used to make the water in the pre-frozen material sublimate directly into water vapor in the form of ice without melting the ice, thereby achieving the purpose of freeze drying. The main disadvantage of the freeze dryer currently on the market in the process of freeze drying probiotics is that the freeze drying efficiency is low, resulting in a long freeze drying time, which is not conducive to improving the production efficiency of probiotics.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] A high-efficiency freeze-drying device comprises: a frame 1, a refrigeration device 2, a rack 3, and a connecting pipe assembly 4. The refrigeration device 2 is fixed in the frame 1, and freeze drying is performed by the refrigeration device 2. The rack 3 is installed in the frame 1 in a pull-out manner. Probiotics to be freeze-dried are placed in the rack 3. A refrigeration pipeline 5 is installed in the rack 3. The connecting pipe assembly 4 is respectively connected to the refrigeration device 2 and the refrigeration pipeline 5. The refrigerant in the refrigeration device 2 flows into the refrigeration pipeline 5. The refrigerant in the refrigeration device 2 flows into the rack 3 through the connecting pipe assembly. The rack 3 is quickly cooled through the refrigeration pipeline 5, thereby improving the freeze-drying efficiency of the probiotics in the rack 3, thereby improving the freeze-drying efficiency of the probiotics.

[0030] The connecting pipe assembly 4 includes a flexible connecting pipe 4-1 and a pipe winding piece. The two ends of the flexible connecting pipe 4-1 are respectively connected to the refrigeration device 2 and the refrigeration pipeline 5, so that the refrigerant in the refrigeration device 2 can flow into the refrigeration pipeline 5. The flexible connecting pipe 4-1 runs through the pipe winding piece. When the pipe winding piece rotates, the flexible connecting pipe 4-1 is wound on the pipe winding piece, thereby winding and storing the flexible connecting pipe 4-1. When the storage rack 3 is pulled out from the rack 1, the pipe winding piece rotates, and the flexible connecting pipe 4-1 wound on the pipe winding piece extends out, thereby ensuring that the storage rack 3 can be pulled out from the rack 1.

[0031] The pipeline winding member includes a winding shaft 4-2, an installation shaft 4-3 and a torsion spring 4-4. The winding shaft 4-2 is provided with a through hole 4-5. The flexible connecting tube 4-1 is inserted in the through hole 4-5, so that the flexible connecting tube 4-1 is twisted and wound along with the winding shaft. The installation shaft 4-3 is connected to one side end of the winding shaft 4-2. The winding shaft 4-2 is rotatably installed in the frame 1 through the installation shaft 4-3. The torsion spring 4-4 ​​is installed outside the installation shaft 4-3, and the two ends of the torsion spring 4-4 ​​are respectively connected to the frame 1 and the installation shaft 4-3. Under normal circumstances, the flexible connecting tube 4-1 is wound around the winding shaft 4-2. When the storage rack 3 is pulled out, the winding shaft 4-2 rotates, and the flexible connecting tube 4-1 extends out from the winding shaft 4-2, thereby ensuring that the storage rack 3 is pulled out; when the storage rack 3 is placed in the frame 1, the winding shaft 4-2 is reversely rotated by the torsion spring, and the flexible connecting tubes 4-1 at both ends of the through hole 4-5 are wound around the winding shaft 4-2.

[0032] The rack 3 is provided with a turning mechanism 3-1 and a grinding mechanism 3-2. The turning mechanism 3-1 is slidably installed on the rack 3. When the turning mechanism 3-1 slides, the probiotics attached to the bottom surface of the rack 3 are scooped up by the turning mechanism 3-1, which is convenient for refining the freeze-dried probiotic blocks. The grinding mechanism 3-2 is installed on the turning mechanism 3-1 to grind the material turned up by the turning mechanism 3-1. The probiotics are further refined by the grinding mechanism 3-2, thereby further improving the production efficiency of the probiotics.

[0033] The material turning mechanism 3-1 includes a sliding bracket 3-1-1, a sliding drive member 3-3 and a turning block 3-1-3. The sliding bracket 3-1-1 is slidably installed on the storage rack 3. The turning block 3-1-3 is fixed on the sliding bracket 3-1-1, and the turning block 3-1-3 is adapted to the storage rack 3, that is, the turning block 3-1-3 is in contact with the bottom surface of the storage rack 3, the sliding drive member 3-3 is connected to the sliding bracket 3-1-1, the sliding drive member 3-3 drives the sliding bracket 3-1-1 to move, and the turning block 3-1-3 moves with the sliding bracket 3-1-1, so that the probiotics are shoveled up by the turning block 3-1-3.

[0034] In some preferred embodiments, in order to facilitate scooping up the probiotics by the turning block 3-1-3, the turning block 3-1-3 is in a trapezoidal structure, so that the probiotics can be scooped up during the movement of the turning block 3-1-3.

[0035] The sliding bracket 3-1-1 includes a connecting part 3-1-4 and a mounting part 3-1-5. The connecting part 3-1-4 is installed at the bottom of the rack 3 through a slide rail slider assembly 3-4 to ensure the movement stability of the sliding bracket 3-1-1. The two ends of the connecting part 3-1-4 are connected with mounting parts 3-1-5. The mounting parts 3-1-5 extend into the rack 3 to facilitate the connection between the sliding bracket 3-1-1 and the turning block 3-1-3. The turning block 3-1-3 and the grinding mechanism 3-2 are respectively connected to the mounting part 3-1-5.

[0036] The sliding drive member 3-3 includes a screw rod 3-3-1, a driving motor 3-3-2 and a screw nut 3-3-3. The driving motor 3-3-2 is connected to the screw rod 3-3-1. The screw nut 3-3-3 is installed on the screw rod 3-3-1, and the screw nut 3-3-3 is fixed to the connecting part 3-1-4. The sliding bracket 3-1-1 is moved by the screw rod 3-3-1 to ensure that the turning block 3-1-3 scoops up the probiotics.

[0037] In order to facilitate the installation of the drive motor 3-3-2 at the bottom of the rack 3 and prevent the drive motor 3-3-2 from extending outside the rack 3, the drive motor 3-3-2 is connected to the screw rod 3-3-1 through a belt 3-3-4 and a pulley 3-3-5, so that the drive motor 3-3-2 can be installed on the lower end surface of the rack 3.

[0038] The grinding mechanism 3-2 includes a grinding roller 3-2-1 and a grinding drive. The grinding roller 3-2-1 is rotatably installed between adjacent mounting parts 3-1-5 through a grinding shaft 3-2-2, and the grinding roller 3-2-1 is adapted to the upper end surface of the turning block 3-1-3, that is, the turning block 3-1-3 scoops up the probiotics, so that the probiotics move to the upper end surface of the turning block 3-1-3, and the grinding roller 3-2-1 crushes and refines the probiotics on the upper end surface of the turning block 3-1-3. The grinding drive is connected to the grinding roller 3-2-1 to drive the grinding roller 3-2-1 to rotate.

[0039] The material grinding drive comprises a rack 3-2-3 and a driving gear 3-2-4. The material grinding shaft 3-2-2 extends out of the mounting portion 3-1-5, and the driving gear 3-2-4 is mounted on the material grinding shaft 3-2-2. The rack 3-2-3 is fixed on the upper end surface of the storage rack 3, and the rack 3-2-3 is meshed with the driving gear 3-2-4. Since the position of the rack 3-2-3 is fixed, during the translation of the sliding bracket 3-1-1, the gear 3-2-4 rotates relatively, thereby driving the material grinding roller 3-2-1 to rotate, ensuring that the material grinding roller 3-2-1 can more effectively refine the probiotic blocks and improve the production efficiency of probiotic freeze-drying.

[0040] A slot 7 is formed on the inner wall of the frame 1 , and an inserting strip 6 is formed on the side wall of the storage rack 3 . The inserting strip 6 is adapted to the slot 7 , so that the storage rack 3 can be pulled out easily.
