Description

Technical Field

[0001] The utility model relates to the technical field of freeze dryers, in particular to a fruit freeze dryer. Background Art

[0002] A freeze dryer, also known as a freeze dryer, is a cold drying device that freezes water-containing substances into a solid state and then sublimates the water from the solid state into a gaseous state, thereby removing the water and preserving the substance.

[0003] Since cold air will inevitably encounter resistance and diversion during the transportation process, diversion will cause the cold air to lose some of its coldness during the transmission process, making the temperature of the cold air finally reaching the far end different from that at the near end. Compared with the fruit near the cold air outlet, it takes longer for the fruit in the far end to achieve the expected freeze-drying effect, which will extend the entire freeze-drying cycle and reduce production efficiency. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 5 The utility model provides a fruit freeze dryer, comprising: a main body 5, a freeze drying rack 2 arranged above the main body 5, and a vacuum cover 1 covering the outside of the freeze drying rack 2.

[0027] Since cold air will inevitably encounter resistance and diversion during the transportation process, diversion will cause the cold air to lose some of its coldness during the transmission process, making the temperature of the cold air finally reaching the remote area different from that at the near end. Compared with the fruit near the cold air outlet, it takes longer for the fruit in the remote area to achieve the expected freeze-drying effect, which will extend the entire freeze-drying cycle and reduce production efficiency.

[0028] In order to promote the low-temperature dehydration of fruits and accelerate the internal circulation of frozen cold air to complete freeze-drying in advance, the freeze-drying rack 2 includes a support frame 25, a plurality of ring sleeves 22 longitudinally arranged on the support frame 25, and a plurality of grid linings 21 arranged inside the ring sleeves 22.

[0029] In order to promote the low-temperature dehydration of fruits and accelerate the internal circulation of frozen cold air to complete freeze-drying in advance, the grille lining 21 includes a plurality of lining surfaces 211 and a plurality of inclined filter plates 213 welded at intervals on the lining surfaces 211. Grille gap grooves 212 are formed between adjacent inclined filter plates 213, and the inner side of the inclined filter plates 213 is inclined at an angle of sixty degrees.

[0030] A cold air output pipe 26 is provided above the support frame 25 . The cold air output pipe 26 is communicated with the refrigeration component inside the main body 5 , and the opening of the cold air output pipe 26 faces downward.

[0031] The cold air is released downward through the cold air output pipe 26 to impact the uppermost grille lining plate 21 , and guided by the inclined filter plate 213 and the grille slit groove 212 , the cold air impacts the middle of the adjacent grille lining plate 21 below, thereby gathering and impacting the cold air layer by layer.

[0032] In order to achieve significant vacuum sealing and vacuum refrigeration operation effects, the preliminary assembly work parts need to be strictly coordinated, and also include a sealing ring 3 arranged under the vacuum cover 1, and the sealing ring 3 is inserted above the main body 5.

[0033] In order to stabilize the freeze-drying rack 2 and prevent it from tipping over and affecting the fruit freeze-drying process, a reinforcing rib plate 23 is tightly attached to the bottom of the lining surface 211 . Two reinforcing rib plates 23 are provided and are horizontally welded to the bottom of the ring sleeve 22 in a cross-shaped manner.

[0034] In order to prevent the freeze-drying rack 2 from tipping over and affecting the fruit freeze-drying operation process, a group of positioning components 24 are fixed below the reinforcing rib plate 23, and the positioning components 24 are set at the left and right lower corners of the reinforcing rib plate 23.

[0035] In order to prevent the freeze-drying rack 2 from tipping over and affecting the fruit freeze-drying operation process, the positioning assembly 24 includes a positioning frame 241 and a snap-on bolt cap 242. The positioning frame 241 is embedded and installed on the inner side of the support frame 25, and the snap-on bolt cap 242 is installed inside the positioning frame 241 by rivet connection.

[0036] In order to promote the internal circulation of cold air settlement for high-level cooling, there are four grille linings 21, and they are all embedded in the ring sleeves 22 and laid horizontally. There are three groups of ring sleeves 22, and the ring sleeves 22 are fixed on the support frame 25 through the positioning assembly 24. The bottom of the support frame 25 is inserted and fixed inside the main body 5.

[0037] In order to connect the entire circuit in series and prevent short circuit and open circuit, the surface equipment has the working effect of a closed loop. The front face of the main body 5 is tightly attached to the touch screen 4, and the front side and left and right sides of the main body 5 are welded with heat dissipation network ports 7. A switch 6 is installed in the upper left corner of the main body 5. The switch 6 starts the power supply and turns on the circuit in the main body 5 in series with the touch screen 4 to manually control the working status of the refrigeration component.

[0038] The staff assembles the vacuum cover 1 with the built-in freeze-drying rack 2, which is put on the sealing ring 3 and the main body 5. The staff turns on the switch 6 to turn on the power circuit to the touch screen 4 to facilitate the operation of the freeze dryer to freeze-dry the fruit. Then, when the main body 5 is overheated, the heat can be dissipated through the heat dissipation network port 7. Then the staff places the fruit on the grille lining 21 and the ring sleeve 22, and uses the reinforcing ribs 23 and the positioning components 24 to support the load-bearing layered frame on the support frame 25, so that the lining 211 and the positioning frame 241 support the snap bolt cap 242 at a right angle to the fixed position and the load-bearing structure. Then, the high-position condenser 26 is used in conjunction with the freezing and cooling treatment to integrate the cold air dehydration and freeze-drying operations in the vacuum environment of the vacuum cover 1. The grille slit groove 212 and the inclined filter plate 213 form an internal cold air circulation effect to increase the freeze-drying efficiency, ensuring that the freeze-drying cycle of large quantities of fruit can be compressed, the time cost can be shortened, and the amount of frozen fruit can be increased.
