Technical Field

[0001] The present invention relates to the technical field of pet food, and particularly to a preparation device and a preparation process for pet freeze-dried instant soluble soup. Background Technique

[0002] Pet food is specially provided for pets and small animals, and is a high-grade animal food between human food and traditional livestock and poultry feed. Its main function is to provide the most basic life guarantee, growth and development, and nutrients required for health for various pets. It has the advantages of comprehensive nutrition, high digestion and absorption rate, scientific formula, quality standards, convenient feeding and use, and can prevent certain diseases. Pet food is divided into dry pet food, such as: fish food, dog food, cat food, and leisure snacks; semi-dry pet food, such as: pet canned food, homemade dog food, cat food; pet liquid food, such as: pet meat paste, pet nutritional porridge, and so on.

Detailed implementation manners

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Example 1: Refer to Figure 1 , 2 , which is the first embodiment of the present invention. This embodiment provides a preparation device for pet freeze-dried instant soluble soup, including a freeze dryer 1. A conveying track 2 is arranged on one side of the freeze dryer 1. A conveying motor 3 is fixedly installed at one end of the conveying track 2. A material tray 4 is arranged on the conveying track 2. The material tray 4 is arranged at the bottom of the filling device 5. The two sides of the bottom of the filling device 5 are respectively fixedly connected to the conveying track 2;

[0033] The perfusion device 5 includes a housing 51, support legs 52, a double-output shaft motor 53, a bracket 54, a stirring assembly 55, a universal coupling 56, a transmission assembly 57, a turntable 58, and a discharge chute 59. Support legs 52 are fixedly connected to both sides of the bottom of the housing 51. One support leg 52 is rotatably connected to the transmission assembly 57. The transmission assembly 57 is connected to one end of the universal coupling 56 through bevel gears. The universal coupling 56 is rotatably installed on one side outside the housing 51. The other end of the universal coupling 56 is connected to the double-output shaft motor 53 through bevel gears. The double-output shaft motor 53 is fixedly installed on the top of the bracket 54. The bracket 54 is fixedly installed on the top inside the housing 51. A stirring assembly 55 is rotatably provided at the bottom of the housing 51. The stirring assembly 55 is fixedly connected to the double-output shaft motor 53. A turntable 58 is provided at the bottom of the stirring assembly 55. The turntable 58 is rotatably provided inside the housing 51. A number of discharge chutes 59 are provided on the circumference of the turntable 58;

[0034] The prepared soup stock is injected into the perfusion device 5. The double-output shaft motor 53 of the perfusion device 5 operates. The double-output shaft motor 53 drives the stirring assembly 55 to operate. The stirring assembly 55 stirs the soup stock, ensuring the uniformity of the soup stock. At the same time, the stirring assembly 55 prevents the soup stock from sticking to the wall. The soup stock falls into the discharge chute 59 of the turntable 58 under the action of gravity. The double-output shaft motor 53 drives the turntable 58 to rotate intermittently through the transmission assembly 57. The turntable 58 then drives the discharge chute 59 filled with the soup stock to rotate. After the discharge chute 59 rotates to the bottom, the soup stock inside is discharged, and the discharged soup stock falls on the material tray 4;

[0035] A number of storage grooves 41 are provided on the top of the material tray 4. A top plate 42 is movably provided inside the storage groove 41. The bottom end of the top plate 42 is fixedly connected to a movable rod 46. The end of the movable rod 46 away from the top plate 42 is fixedly connected to a piston 48. The piston 48 is slidably sleeved inside a cylindrical cavity 47. One end of a spring 49 is fixedly connected to the inner wall of the cylindrical cavity 47. The other end of the spring 49 is fixedly connected to the piston 48.

[0036] The soup stock falls into the storage groove 41 of the material tray 4. At the same time, the soup stock presses down on the top plate 42 under its own weight, increasing the capacity of the soup stock perfusion. After the top plate 42 is pressed down, it drives the movable rod 46 to move. The movable rod 46 then drives the piston 48 to move. The piston 48 squeezes the air inside the cylindrical cavity 47. At the same time, the piston 48 compresses the spring 49. After one storage groove 41 of the material tray 4 is perfused, the conveying motor 3 operates, driving the material tray 4 to move a certain distance, so that the next storage groove 41 moves to the bottom of the perfusion device 5, realizing the perfusion operation for the new storage groove 41. After the entire material tray 4 is perfused, the conveying motor 3 cooperates with the conveying track 2 to drive the material tray 4 to move to the position of the freeze dryer 1. Finally, the material tray 4 is placed into the freeze dryer 1 for freeze-drying operation.

[0037] Example 2: Refer to Figure 1-6, which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the top of the housing 51 is hollow and provided with a material storage cavity 511. The bottom of the material storage cavity 511 is communicated with a movable cavity 512. The bottom of the movable cavity 512 is communicated with a discharge port 513. The discharge port 513 is opened at the bottom end of the housing 51. The movable cavity 512 is hollow and arranged in the middle of the housing 51. The turntable 58 is rotatably arranged in the movable cavity 512.

[0038] The prepared soup stock is injected into the material storage cavity 511 of the perfusion device 5. Under the action of gravity, the soup stock enters the communicated movable cavity 512. The turntable 58 is rotatably arranged in the movable cavity 512. At the same time, the top discharge groove 59 is communicated with the material storage cavity 511. Then, after entering the movable cavity 512, the soup stock falls into the discharge groove 59.

[0039] Furthermore, the stirring assembly 55 is movably arranged in the material storage cavity 511. The stirring assembly 55 includes a transmission shaft 551, a support rod 552, and a scraping strip 553. One end of the transmission shaft 551 is fixedly connected to the double-output shaft motor 53. A plurality of support rods 552 are fixedly connected to the circumferential side of the transmission shaft 551. The end of the support rod 552 away from the transmission shaft 551 is fixedly connected to the scraping strip 553. The scraping strip 553 is in sliding contact with the inner wall of the material storage cavity 511.

[0040] The double-output shaft motor 53 works, driving the transmission shaft 551 of the stirring assembly 55 to rotate. The transmission shaft 551 drives the fixedly connected support rods 552 to rotate circumferentially. The support rods 552 stir the soup stock in the material storage cavity 511 to prevent the soup stock from coagulating and ensure the uniformity of the soup stock. When the support rods 552 rotate circumferentially, they drive the fixedly connected scraping strip 553 to rotate circumferentially. After the scraping strip 553 rotates circumferentially, it scrapes and moves the inner wall of the material storage cavity 511 to prevent the soup stock from sticking to the wall.

[0041] Furthermore, the scraping strips 553 are annularly and evenly arranged with the transmission shaft 551 as the center. The transmission shaft 551 is coaxially arranged with the material storage cavity 511. The bottom of the support rod 552 is provided with a slope inclined downward.

[0042] The coaxial arrangement ensures the stability of the rotation of the transmission shaft 551. The inclined downward slope of the support rod 552 applies a certain downward pressure to the soup stock when the support rod 552 rotates circumferentially, improving the driving force for the downward discharge of the soup stock.

[0043] Specifically, the transmission assembly 57 includes a rotating shaft 571, a limit plate 572, a rocker arm 573, and a transmission plate 574. The rotating shaft 571 is rotationally connected to the shell body 51 and the support leg 52 respectively. One end of the rotating shaft 571 is transmission-connected to the universal coupling 56, and the other end of the rotating shaft 571 is fixedly sleeved on the limit plate 572. One side of the limit plate 572 is fixedly connected to the rocker arm 573. One end of the rocker arm 573 away from the limit plate 572 is rotationally connected to a cylindrical pin. The bottom of the limit plate 572 slides in contact with the transmission plate 574. The transmission plate 574 is rotationally connected to the shell body 51 through the fixed support rotating shaft, and the end of the supporting rotating shaft is fixedly connected to the turntable 58.

[0044] Furthermore, a fan-shaped opening is provided on one side of the limit plate 572, and the rocker arm 573 is fixed in the middle of the fan-shaped opening. A plurality of arc-shaped openings 576 are provided on the circumferential side of the transmission plate 574, and the arc-shaped openings 576 are engaged with the limit plate 572. The limit plate 572 prevents the transmission plate 574 from rotating by itself, thereby ensuring the stability of the position of the transmission plate 574. A rectangular opening 575 is provided between two adjacent arc-shaped openings 576, and the rectangular opening 575 is engaged with the cylindrical pin. When the cylindrical pin rotates in a circle, it cooperates with the rectangular opening 575 to drive the transmission plate 574 to rotate, thereby realizing intermittent discharging operation. There are four rectangular openings 575, and there are four discharging grooves 59. The corresponding number of rectangular openings 575 and discharging grooves 59 ensure the stability of intermittent perfusion and the quantitative quality of the perfused soup.

[0045] When the dual-output shaft motor 53 is working, the universal coupling 56 is driven to rotate through the bevel gear transmission, and the universal coupling 56 drives the rotating shaft 571 of the transmission assembly 57 to rotate, and the rotating shaft 571 further drives the limit plate 572 to rotate, and the limit plate 572 synchronously drives the swing rod 573 to rotate in a circle with the rotating shaft 571 as the center. After the swing rod 573 rotates, it drives the rotating connected cylindrical pin to be inserted into the rectangular opening 575 of the transmission plate 574. After the cylindrical pin continues to rotate in a circle, it drives the transmission plate 574 to rotate 90 degrees. The transmission plate 574 drives the fixed turntable 58 to rotate synchronously. After the turntable 58 rotates, it drives the discharge trough 59 to rotate synchronously. After the discharge trough 59 filled with soup rotates to the bottom, the soup is discharged from the discharge port 513 under the action of gravity, and then falls into the storage trough 41 of the material tray 4.

[0046] Specifically, a plug-in groove 43 is concavely provided at the bottom of one side of the material tray 4, and a slow-motion component 40 is movably provided in the plug-in groove 43. The slow-motion component 40 is connected to the cylindrical cavity 47. A storage groove 44 is concavely provided at the bottom of the other side of the material tray 4, and a plug-in rod 45 is hinged in the storage groove 44.

[0047] When freeze-drying operation is required, multiple material trays 4 are spliced ​​together. During splicing, the plug-in rod 45 is inserted into the plug-in groove 43. The setting of the storage groove 44 facilitates the insertion of the plug-in rod 45, so that after the material tray 4 is placed on the conveying track 2, the plug-in rod 45 is prevented from obstructing the transmission of the material tray 4.

[0048] Further, an annular groove 451 is formed on the circumferential side of one end of the insertion rod 45, and a limiting rubber ring 431 is fixedly installed inside the insertion slot 43. The limiting rubber ring 431 is in clamping fit with the annular groove 451. When the insertion rod 45 is inserted into the insertion slot 43 and the limiting rubber ring 431 is sleeved into the annular groove 451, the clamping fit of the limiting rubber ring 431 with the annular groove 451 prevents the insertion rod 45 from detaching, ensuring the stability after splicing of multiple material trays 4.

[0049] Further, the slow-moving assembly 40 includes a control valve 401, a push rod 402, a valve rod 403, a return spring 404, an airbag 405, and a connecting channel 406. The push rod 402 is movably arranged inside the insertion slot 43. One end of the push rod 402 is fixedly connected to one end of the return spring 404, and the other end of the return spring 404 is fixedly connected to the control valve 401. The control valve 401 is movably connected to the valve rod 403. The valve rod 403 is movably arranged inside the return spring 404. One side of the control valve 401 communicates with the airbag 405. The airbag 405 is movably arranged inside the cavity formed in the material tray 4. One side of the control valve 401 communicates with a connecting channel 406, and the end of the connecting channel 406 far from the control valve 401 communicates with the cylindrical cavity 47.

[0050] After the soup stock is poured into the storage tank 41 of the material tray 4 through the pouring device 5, under the action of its own weight, the soup stock presses down on the top plate 42. After the top plate 42 is pressed down, it drives the movable rod 46 to move downward. The movable rod 46 drives the piston 48 to move downward. The piston 48 compresses the spring 49. At the same time, the piston 48 squeezes the air in the cylindrical cavity 47. The air enters the airbag 405 through the connecting channel 406 and the control valve 401 for storage. After multiple material trays 4 are spliced, the insertion rod 45 squeezes the push rod 402 of the slow-moving assembly 40. The push rod 402 drives the valve rod 403 to move. The valve rod 403 closes the control valve 401 to prevent the gas in the airbag 405 from flowing back. The spliced material trays 4 are placed in the freeze dryer 1 for freeze-drying operation. After freeze-drying is completed, the weight of the soup stock decreases. The elastic force of the spring 49 is greater than the weight of the freeze-dried soup block. Therefore, after the spliced material trays 4 are disassembled, the push rod 402 loses the restriction of the insertion rod 45. The elastic force of the return spring 404 drives the push rod 402 to move. The push rod 402 is fixedly connected to the valve rod 403, and thus synchronously drives the valve rod 403 to move. The control valve 401 is then connected. The elastic force of the spring 49 drives the piston 48 to move. At the same time, the piston 48 extracts the air stored in the airbag 405 through the connecting channel 406. The air slowly flows back into the cylindrical cavity 47. The elastic force of the spring 49 cooperates with the air pressure of the slowly flowing back air, slowly driving the top plate 42 to rise, avoiding the large elastic force of the spring 49 from causing the freeze-dried soup block to fly off. After the top plate 42 rises, it lifts the freeze-dried soup block, facilitating the removal of the freeze-dried soup block.

[0051] Example 3: Refer to Figure 1-6, which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. A preparation process of pet freeze-dried instant soup includes the following steps:

[0052] S1. Ingredient preparation: Select ingredient raw materials with good color, no pests and diseases, and good quality.

[0053] S2. Ingredient processing: Rinse the ingredient raw materials clean with a washing machine, drain the water after washing, cut the washed ingredients into sections with a vegetable cutter, and directly reserve them after cutting according to the characteristics of the ingredients, or blanch them in boiling water and then reserve them after cutting.

[0054] S3. Soup stock boiling and modulation: Boil fresh chicken, pig bones, beef bones or fish into thick soup, add the thick soup, starch, maltodextrin, salt, chicken powder, stabilizer, and antioxidant into water, heat it over low heat until the seasoning liquid becomes paste-like, and add yeast for fermentation.

[0055] S4. Filling and loading: Inject the soup stock in S3 into the storage cavity 511 of the filling device 5. The double-output shaft motor 53 works to drive the stirring assembly 55 to stir the soup stock in the storage cavity 511 to prevent the soup stock from coagulating and sticking to the wall, and ensure the uniformity of the soup stock. The soup stock enters the discharge groove 59 of the turntable 58 under the action of gravity. At the same time, the double-output shaft motor 53 drives the transmission assembly 57 to work. The transmission assembly 57 drives the turntable 58 to rotate intermittently, and then drives the discharge groove 59 to rotate intermittently by 90 degrees. The soup stock in the discharge groove 59 finally falls into the storage groove 41 of the material tray 4 through the discharge port 513. The top plate 42 is pressed down by the self-weight of the soup stock. The conveying motor 3 works step by step to drive the conveying track 2 to move step by step. The conveying track 2 drives the material tray 4 to move, so that the filling device 5 fills the storage grooves 41 opened on the material tray 4 respectively. After the filling is completed, the conveying track 2 drives the material tray 4 to convey towards the freeze-dryer 1.

[0056] S5. Freeze-drying: After splicing multiple material trays 4 in S4, during splicing, the insertion rod 45 is inserted into the insertion slot 43 to ensure the connection stability of the mutually spliced material trays 4. Then, the spliced material trays 4 are sent into the freeze-dryer 1, and the freeze-dryer 1 is sealed for freeze-drying operation.

[0057] S6, Sorting, Packaging and Warehousing: After the material tray 4 is taken out from the freeze dryer 1 and the freeze drying is completed, the weight of the soup material decreases. The elastic force of the spring 49 is greater than the weight of the freeze-dried soup block. Then, after the spliced material tray 4 is disassembled, the ejector rod 402 loses the restriction of the insertion rod 45. The elastic force of the return spring 404 drives the ejector rod 402 to move. The ejector rod 402 is fixedly connected to the valve rod 403, and then synchronously drives the valve rod 403 to move, so that the control valve 401 is connected. The elastic force of the spring 49 drives the piston 48 to move. At the same time, the piston 48 extracts the air stored in the airbag 405 through the connection channel 406. The air slowly flows back into the cylindrical cavity 47. The elastic force of the spring 49 cooperates with the slowly flowing back air pressure to slowly drive the top plate 42 to lift, avoiding the large elastic force of the spring 49 from making the freeze-dried soup block fly off. After the top plate 42 is lifted, it lifts the freeze-dried soup block, which is convenient for taking out and inspecting the freeze-dried soup block. The inspectors check whether the colors, shapes and drying degrees of the freeze-dried soup blocks are consistent, pick out the unqualified soup blocks in time, and package the qualified soup blocks.

[0058] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
