Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular discloses a raw food thawing device for processing marinated products. Background Art

[0002] In the process of preparing marinated products, some purchased raw ingredients are frozen and transported for preservation, which requires thawing of the raw ingredients before pickling. At present, the thawing of raw ingredients in the industry is usually done in a thawing pool. During the thawing process, the frozen raw ingredients are put into the pool water, and then the thawing of the raw ingredients can be accelerated by heating the water or using an air pump to generate bubbles. However, during the above thawing process, the raw ingredients are soaked in water for a long time, which makes some meat products easily deteriorate after thawing, seriously affecting the taste of the final marinated products.

[0003] For example, the utility model patent with application number 202021818080.9 discloses a thawing pool, including a pool body, a steam heating component and a water supply component; the top of the pool body is open, the water supply component includes a main water supply pipe and an auxiliary water supply pipe, two auxiliary water supply pipes are provided, the main water supply pipe is connected to an external water source, one end of the two auxiliary water supply pipes are connected to the main water supply pipe, and the other end of the two auxiliary water supply pipes transports water toward the pool body; the steam heating component includes an air supply pipe and a vent pipe, the vent pipe is arranged inside the pool body to transport hot steam into the pool body, one end of the air supply pipe is connected to the vent pipe, and the other end of the air supply pipe is connected to the external high-pressure hot steam. Although the thawing pool disclosed in the utility model patent can quickly thaw meat products, the water in the pool body maintains a certain temperature after heat exchange with steam, and the quality of meat products will be affected if they are in a warm water environment for a long time. In addition, the thawing speed of warm water thawing is relatively slow, especially for some block-shaped meats. Although the outer part can be thawed quickly after heat exchange with warm water, the inner layer cannot be fully in contact with the warm water, resulting in a slow thawing speed of the inner layer and inability to effectively pickle. Therefore, in view of the shortcomings of the existing thawing pool when used for thawing the raw materials of marinated products, this application proposes a newly designed thawing equipment to achieve fast and uniform thawing while avoiding the deterioration of the raw materials during the thawing process. Summary of the invention

[0004] The present invention aims to provide a raw food thawing device for marinated product processing using microwave thawing, so as to achieve rapid and uniform thawing of frozen raw food, avoid deterioration of the raw food during the thawing process, and maintain the freshness of the raw food after thawing.

[0005] The present invention is achieved through the following technical solutions: A raw material thawing device for marinated product processing comprises a chassis, wherein both ends of the chassis are sealed and penetrated with a feeding unit, an upper surface of one end of the feeding unit extending out of the chassis is connected to a feeding mechanism, and a lower surface of the other end of the feeding unit extending out of the chassis is connected to a feeding portion, and a microwave thawing mechanism is arranged inside the chassis; The microwave thawing mechanism includes a plurality of rotating rings arranged side by side and rotating on the periphery of a feeding unit, and a rotating driving assembly for realizing synchronous rotation of the plurality of rotating rings around the center of the feeding unit is arranged in the chassis, a plurality of microwave generators arranged radially toward the feeding unit are evenly fixed circumferentially on each of the rotating rings, a carbon brush device is arranged on the side end of the microwave generator, a concentrically arranged insulating ring plate is fixed on one side of each of the rotating rings, a positive copper ring sheet and a negative copper ring sheet acting on the carbon brush device are arranged on the insulating ring plate, and the positive copper ring sheet and the negative copper ring sheet are connected to a power circuit through electric wires.

[0006] When the raw food material thawing equipment for marinated product processing disclosed by the present invention thaws frozen raw food materials, a feeding mechanism first squeezes and separates the raw food materials that are frozen together, and then the separated materials enter a feeding unit, which moves and transports the raw food materials from one end to the other end, so that the raw food materials pass through the inside of a chassis during the moving and transporting process.

[0007] During the operation of the microwave thawing mechanism inside the chassis, the rotary drive assembly causes the multiple rotating rings spaced apart on the periphery of the feeding unit to rotate synchronously at a set speed, allowing the microwave generator installed on the rotating ring to rotate 360°, so that the microwave signal emitted by the microwave generator can act evenly on the food inside the feeding unit from multiple angles, so that the food is thawed evenly. At the same time, as the microwave generator rotates with the rotating ring, the carbon brush device ensures that the microwave generator is always stably connected to the external circuit, ensuring that the microwave generator can thaw the food at the center from 360°. Finally, after the thawing is completed, the food is discharged from the unloading part of the entire thawing device and collected.

[0008] As a specific setting of the above scheme, the feeding unit includes a feeding barrel arranged through the chassis, a rotating shaft is arranged inside the feeding barrel, and an auger spiral blade is arranged on the rotating shaft, and a feeding motor for driving the rotating shaft is arranged at the end of the feeding barrel, and the feeding barrel, the rotating shaft and the auger spiral blade are all made of plastic. The above is one of the specific design schemes of the feeding unit, which can concentrate the material in the feeding barrel and advance it at a set speed uniformly under the premise of ensuring that the microwave signal is not shielded, and combined with the 360° all-round microwave thawing treatment, it can more conveniently achieve uniform thawing of the material.

[0009] As a further arrangement of the above scheme, the rotating shaft is hollow, and a hollow tube is concentrically fixed in the inner cavity of the rotating shaft, a connecting port is provided at the inner end of the connection between the hollow tube and the rotating shaft, the outer end of the hollow tube and the rotating shaft are commonly connected with a sealing end cover, and the hollow tube is connected with the water inlet cavity in the sealing end cover, the rotating shaft is connected with the water outlet cavity in the sealing end cover, and the sealing end cover is connected with a heating water tank through a pipeline and an infusion pump.

[0010] As a specific setting of the above scheme, the interior of the sealing end cover is divided into a water inlet chamber and a water outlet chamber by a sealing bearing, and the sealing end cover is provided with a water inlet pipe and a water outlet pipe respectively connected to the water inlet chamber and the water outlet chamber, and the pipeline is connected to the water inlet pipe and the water outlet pipe.

[0011] The present invention further adopts the above-mentioned design. While the microwave thawing mechanism performs 360° uniform thawing treatment on the food inside the feeding unit, hot water can also be circulated into the interior of the rotating shaft, so that the rotating shaft dissipates the heat of the hot water from the inside to the surroundings, thereby thawing the inner layer of the food close to the rotating shaft. The two thawing methods are carried out simultaneously, which not only improves the thawing speed, but also avoids the problem of uneven microwave thawing treatment of the inner and outer layers of food, thereby ensuring the uniformity of the overall thawing of the food inside the feeding unit.

[0012] As a specific setting of the above scheme, a bearing connected to the outer surface of the feed barrel is provided at one end of the inner ring of the rotating ring, and the insulating ring plate is concentrically sleeved on the periphery of the feed barrel and fixedly connected to the inner wall of the chassis through the outer protrusion of the side end.

[0013] As a specific setting of the above scheme, the rotary drive assembly includes a rotating rod rotatably arranged inside the chassis and parallel to the feeding barrel, the rotating rod is provided with a gear corresponding to each rotating ring, and the end of the rotating rod is connected to a rotating motor, and a large gear ring meshing with the corresponding gear is provided on the outer circular surface of the rotating ring near one end of the bearing.

[0014] As a specific configuration of the above solution, a plurality of radially concave mounting grooves are evenly arranged on the outer circumferential surface of one end of the rotating ring away from the bearing, and the microwave generator is fixedly arranged in the mounting groove.

[0015] The above is a design scheme for the specific installation structure of the microwave thawing mechanism and the feeding unit. Through the connection of the bearing, the rotating ring can stably rotate around the central axis of the feeding barrel, so that the microwave generator arranged in the installation groove can evenly defrost the food inside the feeding barrel from 360°, and ensure that the carbon brush device is stably connected to the external circuit during rotation.

[0016] As a further configuration of the above scheme, a plurality of groups of drainage holes are arranged at intervals on the lower surface of the feed cylinder inside the chassis, an arc-shaped water receiving trough is arranged below each group of drainage holes, and the lower end of the arc-shaped water receiving trough is connected to a drainage pipe extending out of the chassis.

[0017] By setting the drain holes and the arc-shaped water receiving trough, the thawed water can be discharged from the feeding barrel in time during the process of the material moving along the feeding barrel for thawing, thereby avoiding the accumulation of water inside the feeding barrel. Combined with the microwave effect, the water temperature is increased to affect the deterioration of the food due to the warm water.

[0018] As a further configuration of the above scheme, the carbon brush device includes two insulating guide tubes fixedly connected to the microwave generator, each of the insulating guide tubes is connected to a carbon column extending therefrom through a spring, the outer end of the carbon column is provided with a carbon brush block that acts on the positive copper ring sheet or the negative copper ring sheet, and the inner end of the carbon column is provided with a wire connected to the internal circuit of the microwave generator.

[0019] The above is a further arrangement of the carbon brush device, which uses the supporting force of the spring to push the carbon column toward the outer end of the insulating guide tube, so that the carbon brush block can effectively contact the positive copper ring sheet or the negative copper ring sheet, ensuring that the circuit can be stably connected during the 360° rotation of the microwave generator.

[0020] As a specific setting of the above scheme, the feeding mechanism includes a feeding hopper, in which two rollers are symmetrically arranged, and a driving assembly is connected to the same side end of the two rollers. Extrusion and crushing rods are arranged on the roller bodies of the rollers, and the extrusion and crushing rods on the two rollers are staggered along the axial direction.

[0021] The above is a specific design scheme for the feeding mechanism. During the feeding process, the frozen raw materials can be squeezed and sheared by two synchronously counter-rotating rollers combined with the action of staggered extrusion and breaking rods, so that the originally frozen together materials can be effectively separated. The separated raw materials can not only be stably transported along the inside of the feeding barrel, but also increase the surface area during thawing, thereby improving the thawing speed and uniformity.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The raw food thawing equipment for marinated product processing disclosed by the present invention adopts microwave thawing to thaw the food in the transportation process, and adopts a rotating ring as a carrier to allow the microwave generator to rotate 360 ​​degrees during the microwave thawing process, so that the food in the transportation process can be thawed by microwave from multiple directions, which not only improves the thawing rate, but also ensures that the food is thawed evenly, does not cause uneven thawing of the inner and outer layers, and ensures the freshness of the thawed food.

[0023] During the process of the microwave generator in the present invention rotating 360° along with the rotating ring, the microwave generator can always be stably connected to the external circuit through the action between the carbon brush device and the positive copper ring sheet and the negative copper ring sheet, thereby ensuring the continuity of the microwave generator in rotating and thawing the food.

[0024] The present invention further circulates hot water into the rotating shaft at the center of the feeding unit, so that while the microwaves thaw the food from the outside, the inner layer of the food near the central shaft can also simultaneously absorb the heat emitted by the hot water, so that the inner layer of the food can be thawed from the inside to the outside. Combined with the microwave thawing process, the thawing speed of the food can be further improved and the uniformity of the food thawing process can be ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 12 , and describes the application in detail with reference to embodiments. Example 1

[0029] Example 1 discloses a raw food thawing device for marinated food processing, Figures 1 to 3 The main body of the device includes a chassis 1, a feeding unit 2, a microwave thawing mechanism 3 and a feeding mechanism 4. The feeding unit 2 is sealed and penetrates the left and right ends of the chassis 1. The microwave thawing mechanism 3 is arranged inside the chassis 1 and thaws the raw materials during transportation. The feeding mechanism 4 is connected to the upper surface of one end of the feeding unit 2 extending out of the chassis 1, and then a feeding portion is arranged on the lower surface of the other end of the feeding unit 2 extending out of the chassis 1. Finally, a control box 7 for controlling the entire thawing device is arranged outside the chassis 1.

[0030] Reference Figure 3 and attached Figure 7 The entire chassis 1 is composed of a lower rectangular section and an upper semi-cylindrical section connected together. The feeding unit 2 includes a feeding barrel 201 that passes through the center of the semi-cylindrical section of the chassis 1 and is fixedly arranged. A rotating shaft 202 is concentrically arranged inside the feeding barrel 201, and a feeding motor 203 connected to the rotating shaft 202 is arranged on the end face of the feeding barrel 201 close to the feeding mechanism 4. Then, an auger spiral blade 204 that matches the feeding barrel 201 is arranged on the outer circumferential surface of the rotating shaft 202. In order to avoid metal shielding of microwaves, the feeding barrel 201, the rotating shaft 202 and the auger spiral blade 204 are all made of food-grade plastic.

[0031] The feeding mechanism 4 includes a feeding hopper 401 connected to the upper surface of the end of the feeding barrel 201, and two rollers 402 are symmetrically arranged in the feeding hopper 401. The same side end of the two rollers 402 is connected to a driving assembly 403 for realizing synchronous reverse rotation of the two rollers, and then the roller bodies of the two rollers 402 are provided with extrusion and crushing rods 404, and the extrusion and crushing rods 404 on the two rollers 402 are staggered along the axial direction. Through the design of the above-mentioned feeding mechanism 4, it can separate the raw materials that were originally frozen together (such as frozen chicken wings and frozen meat blocks) by squeezing and crushing rods 404, and then enter the feeding unit 2 for transportation after separation. The feeding part is arranged on the lower surface of the end of the feeding barrel 201 away from the feeding mechanism 4, and includes a feeding channel 205 connected to the lower surface of the feeding barrel 201, and then a guide hopper 206 is fixed on the end surface of the chassis 1 just below the feeding channel 205.

[0032] Reference Figures 3 to 6 The microwave thawing mechanism 3 includes a plurality of rotating rings 301 which are sleeved on the periphery of the feeding barrel 201 at intervals. A bearing 302 connected to the outer surface of the feeding barrel 201 is provided at one end of the inner ring of each rotating ring 301. The rotating ring 301 can rotate around the central axis of the feeding barrel 201 through the connection and support of the bearing 302. A large gear ring 303 is provided on the outer circumferential surface of the rotating ring 301 near one end of the bearing 302. Then, a rotating rod 304 parallel to the feeding barrel 201 is rotatably provided at one side end of the inner cavity of the chassis 1. Gears 305 meshing with the large gear ring 303 on each rotating ring 301 are arranged at intervals on the rotating rod 304. Finally, a rotating motor 306 is connected to one end of the rotating rod 304. Under the drive of the rotating motor 306, combined with the meshing transmission of the large gear ring 303 and the gear 305, all the rotating rings 301 rotate synchronously around the periphery of the feeding barrel 201.

[0033] A plurality of radially concave mounting grooves 307 are evenly arranged on the outer circumferential surface of one end of the rotating ring 301 away from the bearing 302, and a microwave generator 300 is fixedly arranged in each mounting groove 307, and the emitting end of each microwave generator 400 is arranged radially toward the feeding barrel 201 through the through hole on the bottom wall of the mounting groove 307. An insulating ring plate 308 is concentrically arranged on one side of each rotating ring 301 and sleeved on the outer periphery of the feeding barrel 201, and the insulating ring plate 308 is fixedly connected to the inner wall of the chassis 1 through the outer protrusion of the side end. A positive copper ring sheet 309 and a negative copper ring sheet 310 are concentrically fixedly arranged on the side of the insulating ring plate 308 facing the microwave generator 300. The positive copper ring sheet 309 and the negative copper ring sheet 310 are respectively connected to the power circuit through wires, and then a carbon brush device is arranged on the side end of the microwave generator 300 close to the rotating ring 301 to contact the positive copper ring sheet 309 and the negative copper ring sheet 310 and realize circuit conduction.

[0034] For specific carbon brush devices, please refer to the attached Figure 8 , which includes two insulating guide tubes 311 connected to the microwave generator 300, and a carbon column 312 is arranged in the insulating guide tube 311 with the extended end. The outer end of the carbon column 312 is fixedly connected with a carbon brush block 313 that fits with the positive copper ring sheet 309 or the negative copper ring sheet 310, and the inner end of the carbon column 312 is provided with a wire 314 connected to the internal circuit of the microwave generator 300. In addition, an insulating end plate 315 is also provided at the inner end of the carbon column 312, and then a spring 316 that is sleeved on the outer periphery of the carbon column 312 is connected to the insulating end plate 315, and the end of the spring 316 is connected to the end wall of the insulating guide tube 311. Through the structural design of the above-mentioned carbon brush device, the two carbon brush blocks 313 connected to the positive and negative electrodes of the microwave generator 300 can always keep in close contact with the positive copper ring sheet 309 and the negative copper ring sheet 310, thereby realizing the smooth conduction of the circuit during the rotation of the microwave generator 300.

[0035] In order to discharge the water generated by the thawing of the original food during transportation, refer to the attached Figure 3 , Attachment Figure 7 and attached Fig. 9 , a drain hole 207 is provided on the lower surface of the feeding cylinder 201 between two adjacent rotating rings 301, and an arc-shaped water receiving groove 208 is fixedly provided below each set of drain holes 207. The lower end of each arc-shaped water receiving groove 208 is connected to a downpipe 209, and a drain pipe 210 extending out of the chassis 1 is commonly connected between the lower ends of all downpipes 209, so that the water generated during the thawing process of the original food can eventually be discharged from the entire thawing device through the drain pipe 210, so as to avoid the residual water body inside from heating up during the continuous microwave heating process, thereby preventing the high-temperature water body from directly contacting the food and causing deterioration.

[0036] In the thawing process of the thawing device disclosed in the embodiment 1 for thawing raw meat ingredients such as frozen chicken wings and frozen meat blocks, the raw meat ingredients frozen together are first separated by the feeding mechanism 4, and then enter the feeding unit 2. The feeding unit 2 is driven by the feeding motor 203 to rotate the rotating shaft 202 at a set speed. During the rotation of the rotating shaft 202, the raw food is transported from one end of the feeding barrel 201 to the other end through the action of the auger spiral blade 204, and passes through the interior of the chassis 1 during the transportation process.

[0037] When the raw food moves along the inside of the feeding barrel 201 through the inner cavity of the chassis 1, all the rotating rings 301 rotate synchronously under the driving action of the rotating motor 306, and the microwave generator 300 can emit microwave signals from 360° to the center of the feeding barrel 201 during the rotation of the rotating ring 301. At the same time, due to the contact between the carbon brush device and the positive copper ring sheet 309 and the negative copper ring sheet 310 throughout the entire process, the microwave generator 300 is fully connected. Therefore, through 360° microwave treatment, the raw food in the feeding barrel 201 performs electric field polarity movement under high-frequency electronic movement, thereby frequently colliding to generate friction heat, so that each part of the raw food simultaneously obtains heat energy and heats up, realizing the thawing process. In addition, the melted water in the thawing process can drip into the arc-shaped water receiving trough 208 through the drain hole 207, and then discharged from the chassis 1 by the downpipe 209 and the drain pipe 210.

[0038] Finally, when the raw food is transported to the discharge channel 205, the thawing is completed and it is discharged from the discharge channel 205 to the feeding unit 2, and finally introduced into the cleaning tank by the guide hopper 206 for cleaning. After cleaning, the pickling, braising and other processes can be carried out. Example 2

[0039] Example 2 discloses a raw food thawing device for marinated product processing that is improved and designed based on the technical solution in Example 1, and the similarities between it and Example 1 will not be described again.

[0040] Reference Figure 1 , Attachment Fig.10 , Attachment Fig.11 and attached Fig.12 In this embodiment 2, the rotating shaft 202 is designed as a hollow shaft, and one end of the rotating shaft 202 extends out of the end of the feeding cylinder 201. A hollow tube 211 is coaxially fixed in the inner cavity of the rotating shaft 202, and a communication port 212 is provided between the hollow tube 211 and the inner end wall of the cavity of the rotating shaft 202, and the other end of the hollow tube 211 extends out of the open end of the hollow tube 211.

[0041] A sealing end cover 213 matching with the rotating shaft 202 and the hollow tube 211 is arranged on the outer end surface of the feeding barrel 201. The interior of the sealing end cover 213 is divided into a water inlet chamber and a water outlet chamber by a sealing bearing 214. The end of the hollow tube 211 extends into the water inlet chamber and is connected thereto, and the rotating shaft 202 extends into the water outlet chamber and is connected thereto. A water inlet pipe 215 and a water outlet pipe 216 connected to the water inlet chamber and the water outlet chamber are arranged on the side of the sealing end cover 213, respectively. A heating water tank 5 is fixedly arranged on the outer surface of the chassis 1, and then an infusion pump 6 is arranged on the heating water tank 5. A water inlet pipe 601 is connected between the infusion pump 6 and the water inlet pipe 215, and a return water pipe 501 is directly connected between the water outlet pipe 216 and the heating water tank 5.

[0042] Through the above-mentioned improved design, in the present embodiment 2, when the feeding unit 2 feeds the raw food into the chassis 1 for thawing by the microwave thawing mechanism 3, the heating water tank 5 is fed into the hollow tube 211 through the infusion pump 6, and then when the hot water flows along the hollow tube 211 to the end of the inner cavity of the rotating shaft 202, it flows back along the ring between the rotating shaft 202 and the hollow tube 211 through the connecting port 212, so that the inside of the rotating shaft 202 has continuously flowing hot water, and the heat generated by this part of hot water can be diffused from the middle of the feeding tube 201 to the surroundings, so as to heat and thaw the raw food in the center inner layer during the transportation process, and then combined with the 360° microwave thawing treatment on the periphery, it can not only speed up the thawing speed of the food, but also allow the inner and outer layers of the food to thaw at the same time, making the thawing process more uniform and improving the thawing effect.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
