Abstract
Description
Technical Field
[0001] This utility model relates to the field of frozen shrimp thawing technology, and in particular to an integrated industrial microwave thawing and drying device. Background Technology
[0002] Antarctic krill caught in the open ocean need to be frozen and transported to processing plants. Before extracting krill oil, the frozen krill need to be thawed.
[0003] Existing thawing methods utilize microwave heating, which can efficiently and quickly thaw frozen Antarctic krill. However, in practical use, it has been found that frozen krill close to the conveyor belt receive less microwave radiation during thawing. Under the same thawing time, the frozen krill at the bottom thaws poorly, affecting the uniformity of thawing and reducing the efficiency of microwave thawing. This requires longer microwave heating to achieve effective thawing, increasing the energy consumption of Antarctic krill thawing operations. Utility Model Content
[0004] To address the technical problem that frozen shrimp close to the conveyor belt receive less microwave radiation during thawing, resulting in poor thawing of shrimp at the bottom within the same thawing time, affecting the uniformity of thawing, and causing a decrease in the efficiency of microwave thawing of frozen shrimp, requiring longer microwave heating time to achieve effective thawing, and increasing the energy consumption of Antarctic krill thawing operations, this utility model provides an integrated industrial microwave thawing and drying equipment.
[0005] This utility model employs the following technical solution to realize an integrated industrial microwave defrosting and drying equipment, including a workbench, a pair of fixed frames fixed to the top of the workbench, a defrosting box fixed inside the pair of fixed frames, a microwave output device provided on the inner side wall of the defrosting box, a water pipe installed at the bottom of the inner side wall of the defrosting box, the water pipe passing through the workbench surface and having a collection box fixed to its bottom end, a feeding port provided above the defrosting box, a feeding conveyor platform provided above the feeding port, a fixed plate fixed to the vertical parallel side of the workbench, a drying box fixed to the fixed plate, the drying box being connected to the defrosting box, and a discharging conveyor platform provided at the bottom of the drying box.
[0006] The above technical solution uses a microwave output device installed on the inner wall of the thawing box to thaw Antarctic krill transported by the auger blades from all directions. A water pipe is installed at the bottom of the inner wall of the thawing box to collect the thawed water and prevent the water in the thawing box from absorbing microwaves, thus affecting the thawing efficiency of the Antarctic krill. The thawed Antarctic krill is then dried in a drying box for easy processing and storage.
[0007] As a further improvement to the above solution, an auger blade is rotatably connected to the middle of the inner side of the defrosting chamber, a fixing block is fixed to the top of the worktable, and a servo motor coaxial with the auger blade is fixed to the top of the fixing block.
[0008] Through the above technical solution, the servo motor drives the auger blades inside the thawing box to rotate, so that the Antarctic krill to be thawed can be thawed from all directions by a spiral conveyor.
[0009] As a further improvement to the above solution, multiple drying fans are provided on one side of the drying box, and inclined plates are fixed to the two vertically parallel inner side walls of the drying box. The thawing box and the drying box are connected by a connecting pipe, and a vent is provided on the top side of the connecting pipe. The connecting pipe is arranged in an inclined L-shape.
[0010] Through the above technical solution, Antarctic krill from the thawing box are transported to the drying box through connecting pipes. This allows the Antarctic krill to undergo drying and dispersion treatment while flowing towards the bottom of the drying box. Because multiple inclined plates are fixed to the two vertical parallel inner walls of the drying box, the Antarctic krill can turn over when sliding from the first inclined plate to the second inclined plate, thus accelerating the drying efficiency.
[0011] As a further improvement to the above solution, a feed box is fixedly connected to the top side of the thawing box, and the feed inlet is located at the top of the feed box.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention uses a microwave output device installed on the inner wall of a thawing chamber to thaw Antarctic krill transported by a screw conveyor. A water pipe is connected to the bottom of the inner wall of the thawing chamber to collect the thawed water, preventing the water in the thawing chamber from absorbing microwaves and thus affecting the thawing efficiency of the Antarctic krill. The thawed Antarctic krill is then dried in a drying chamber for easier subsequent processing and storage. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0021] Please combine Figures 1-4 This embodiment of an integrated industrial microwave defrosting and drying device includes a workbench 1. A pair of fixed frames 2 are fixed to the top of the workbench 1. A defrosting box 3 is fixed inside the pair of fixed frames 2. A microwave output device 4 is provided on the inner side wall of the defrosting box 3. A water pipe 5 is installed at the bottom of the inner side wall of the defrosting box 3. The water pipe 5 passes through the surface of the workbench 1 and a collection box 6 is fixed to its bottom end. An inlet 7 is provided above the defrosting box 3. An inlet conveyor 10 is provided above the inlet 7. A fixed plate 8 is fixed to the vertical parallel side of the workbench 1. A drying box 9 is fixed to the fixed plate 8. The drying box 9 is connected to the defrosting box 3, and an outlet conveyor 11 is provided at the bottom of the drying box 9.
[0022] The Antarctic krill transported by the screw conveyor blades 12 is thawed from all directions by a microwave output device 4 installed on the inner wall of the thawing box 3. A water pipe 5 is installed at the bottom of the inner wall of the thawing box 3 to collect the thawed water and prevent the water in the thawing box 3 from absorbing microwaves, thus affecting the thawing efficiency of the Antarctic krill. The thawed Antarctic krill is then dried in a drying box 9 for subsequent processing and storage.
[0023] Combination Figure 2 and Figure 3 The defrosting chamber 3 has a screw conveyor blade 12 rotatably connected to the middle of its inner side, and a fixing block 13 is fixedly connected to the top of the worktable 1. A servo motor 14 coaxial with the screw conveyor blade 12 is fixedly connected to the top of the fixing block 13.
[0024] The servo motor 14 at the top of the fixed block 13 drives the auger blades 12 inside the thawing box 3, which is fixed inside the fixed frame 2, to rotate. This allows the Antarctic krill to be thawed to enter through the feed inlet 7 and be conveyed from one end of the thawing box 3 to the connecting pipe 17 in a spiral rotational manner for thawing.
[0025] Combination Figure 2 and Figure 4Multiple drying fans 15 are installed on one side of the drying chamber 9. Inclined plates 16 are fixed to the two vertical parallel inner side walls of the drying chamber 9. The thawing chamber 3 and the drying chamber 9 are connected by a connecting pipe 17. A vent hole 18 is opened on the top side of the connecting pipe 17. The connecting pipe 17 is set in an inclined L-shape. Antarctic krill from the thawing chamber 3 is transported into the drying chamber 9 through the connecting pipe 17, so that the Antarctic krill undergoes drying and dispersion treatment while flowing towards the bottom of the drying chamber 9. Because multiple inclined plates 16 are fixed to the two vertical parallel inner side walls of the drying chamber 9, the Antarctic krill can turn over when sliding from the first inclined plate 16 to the second inclined plate 16, which speeds up the drying efficiency. A feeding box 19 is fixed to the top side of the thawing chamber 3, and the feeding port 7 is located at the top of the feeding box 19.
[0026] Antarctic krill exiting the thawing box 3 are transported to the drying box 9 via an inclined L-shaped connecting pipe 17. This allows the krill to undergo a drying process while simultaneously flowing towards the bottom of the drying box 9. Because multiple inclined plates 16 are fixed to the two vertical parallel inner walls of the drying box 9, the krill can flip over when sliding from the first inclined plate 16 to the second inclined plate 16, thus accelerating the drying efficiency.
[0027] The implementation principle of the integrated industrial microwave defrosting and drying equipment in this application embodiment is as follows:
[0028] Before starting, a large batch of Antarctic krill to be thawed is placed on the surface of the feeding conveyor 10. The krill to be thawed is then conveyed to the feeding port 7 and enters the feeding box 19 from the feeding port 7. From the feeding box 19, the krill enters the thawing box 3 on the workbench 1.
[0029] At this time, the servo motor 14 at the top of the fixed block 13 is turned on to drive the auger blades 12 inside the thawing box 3 to rotate, so that the Antarctic krill that has entered the thawing box 3 moves from one side of the thawing box 3 to the other side in a spiral transport manner after the rotation of the auger blades 12, and is microwave thawed by the microwave output device 4 installed on the inner wall of the thawing box 3 during the movement.
[0030] During this period, the moisture generated by microwave defrosting enters the collection box 6 through the water pipe 5 installed at the bottom of the defrosting box 3.
[0031] Antarctic krill from the thawing box 3 are transported to the drying box 9 via the connecting pipe 17. This allows the krill to undergo a drying process while simultaneously moving towards the bottom of the drying box 9. Because multiple inclined plates 16 are fixed to the two vertical parallel inner walls of the drying box 9, the krill can flip over when sliding from the first inclined plate 16 to the second inclined plate 16, thus accelerating the drying efficiency. Furthermore, the gas generated during drying flows out through the vent 18 at the top of the connecting pipe 17.
[0032] Finally, the dried Antarctic krill are transported from the bottom of the discharge conveyor to the next processing area.
[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
