Description

Technical Field

[0001] The invention relates to the technical field of fresh noodle processing, in particular to fresh noodles with a long shelf life and preparation equipment thereof. Background Art

[0002] Fresh noodles are popular among consumers for their high moisture content, smooth and chewy texture, and strong wheat flavor. At the same time, due to the high moisture content, fresh noodles are also prone to deterioration, prone to mildew during storage, prone to yellowing of the apparent color, and spot browning. Therefore, fresh noodles usually have a short shelf life and are difficult to achieve industrial and large-scale production. Adding alcohol or preservatives and water activity reducers to the ingredient list of fresh noodles, or using alkali to preserve them, however, these treatment methods are prone to produce irritating alcohol odor or strong alkaline odor, and too many additives will also cause consumers to resist and reject them.

[0003] The applicant has observed for a long time that fresh noodles usually go moldy on the surface, cuts or breaks, or areas with high moisture content inside the noodles. The moisture content of noodles processed by a noodle press is significantly lower than that of noodles rolled by hand, and the main moldy situation occurs on the surface and cuts of the noodles. By making improvements here and reducing the invasion of external bacteria, the shelf life of fresh noodles can be extended. Summary of the invention

[0027] The core of the invention is to provide fresh noodles with a long shelf life and a preparation device thereof, and edible auxiliary materials are coated on the surface of the fresh noodles to increase the shelf life of the pressed noodles.

[0028] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] With reference to the accompanying drawings, Figure 1 This is a schematic front view of a section state of the fresh noodle preparation device of the present invention; Figure 2 This is a schematic front view of the noodle pressing state of the fresh noodle preparation device of the present invention; Figure 3 It is a partial cross-sectional schematic diagram of a part of the auxiliary material bin of the fresh noodle making equipment of the present invention in the noodle pressing state; Figure 4 It is a partial cross-sectional schematic diagram of two parts of the auxiliary material bin of the fresh noodle preparation equipment of the present invention in the noodle pressing state; Figure 5 It is a schematic diagram of the enlarged structure of the top rod assembly of the fresh noodle making equipment of the present invention.

[0031] Example 1

[0032] The fresh noodles with long shelf life of the present invention are processed by a noodle press and two sides of the noodles are evenly coated with auxiliary materials before cutting, and the auxiliary materials are corn starch mixed with calcium propionate. When cutting, a cutting roller group is used to press and cut.

[0033] Specifically, the mass percentage of calcium propionate in the auxiliary material is 1% to 2%, and the content of calcium propionate per kilogram of noodles is ensured to be no more than 0.2 grams according to the coating application amount. Calcium propionate, as an anti-mildew component, can effectively inhibit miscellaneous bacteria, and the intake is not harmful to the human body within a reasonable range, and it has no peculiar smell and does not affect the taste. Under normal temperature conditions, the shelf life of ordinary noodles is only 1 to 2 days, while the shelf life of the fresh noodle product in this application can be extended to 4 to 5 days.

[0034] By evenly coating a large surface of the noodle sheet with corn starch containing calcium propionate as an auxiliary material before cutting, it can not only prevent adhesion, but also fully coat the surface of the formed noodles. Auxiliary material powder will also be retained at the pressed incision to prevent bacteria in the surrounding environment from contaminating the noodles, thereby improving the shelf life of the noodles.

[0035] In a specific embodiment of the present invention, the flour raw material used for the dough sheet is sterilized by ultraviolet light before kneading.

[0036] Specifically, the water used for the dough sheets and noodles is warm boiled water or purified water.

[0037] By sterilizing the flour raw materials and using sterile warm boiled water or purified water, the possibility of mold growth inside the noodles can be reduced, thereby extending the shelf life.

[0038] Example 2

[0039] like Figures 1 to 5 As shown, the present invention also discloses a fresh noodle preparation device, which is consistent with the existing noodle machine and also includes a frame 1 and a hopper 2, an upper roller 3, an adjustable noodle pressing roller group 4 and a noodle cutting roller group 5 arranged on the frame 1 from top to bottom. Among them, the hopper 2 is connected by two places of the pin screw 1 202 and the pin screw 2 203 at the bottom. The drive of the upper roller 3, the adjustable noodle pressing roller group 4 and the noodle cutting roller group 5 can adopt a reduction motor to drive the gear group or a handwheel to drive the gear group. This part is the prior art and is not the technical point of this application. Therefore, this application will not repeat it. The drawings in the specification are also omitted. Among them, the diameter of the upper roller 3 is larger than the adjustable noodle pressing roller group 4, and the two upper rollers 3 are arranged in pairs above the adjustable noodle pressing roller group 4. The important difference between the present invention and the existing noodle machines is that the fresh noodle making equipment of the present invention further comprises an auxiliary material bin 1 6 and an auxiliary material bin 2 8, which are respectively arranged above the two upper rollers 3. When cutting noodles, the auxiliary material bin 1 6 and the auxiliary material bin 2 8 can continuously supply the auxiliary materials in Example 1 to the upper rollers 3.

[0040] By adding auxiliary material bin 1 6 and auxiliary material bin 2 8 for storing the auxiliary materials above the upper roller 3, the auxiliary material bin 1 6 and auxiliary material bin 2 8 continuously supply auxiliary materials to the upper roller 3 when cutting, and the upper roller 3 is used to apply the auxiliary materials while pressing the dough sheet, so that the auxiliary materials can be evenly applied on the two large sides of the dough sheet. At the same time, the upper roller 3 applies the auxiliary materials while rolling, and the pressure applied can ensure that the auxiliary materials are half-embedded in the noodles, not easy to fall off, and have a good adhesion effect.

[0041] In a specific embodiment of the present invention, Figures 1 to 4As shown, the fresh noodle making device of the present invention further comprises a movable cover 7 and a push rod assembly 9. A slide rail 101 is arranged on the inner wall of the side plate of the frame 1. The inner end of the lower discharge cut-off plate 10 for receiving the pressed noodle sheet is guided and detachably mounted on the slide rail 101. In a specific embodiment, the slide rail 101 is a horizontal receiving strip. The inner end of the lower discharge cut-off plate 10 is a horizontal plate with the outer end swinging downward. The inner end of the lower discharge cut-off plate 10 is horizontally spaced between the adjustable noodle pressing roller group 4 and the noodle cutting roller group 5. The bottom end of the push rod assembly 9 contacts the side edge of the lower discharge cut-off plate 10 or the slide rail 101. The top pin of the movable cover 7 is connected to the top of the auxiliary material bin 6, specifically through two coaxial pin screws 3601. The bottom end of the movable cover 7 is provided with a coating wheel 1701. The movable cover 7 can block and open the discharge port at the bottom end of the auxiliary material bin 6. The coating wheel 1701 can roll on the lower upper roller 3. The top pin of the auxiliary material bin 28 is connected to the pin screw 203 on the outside of the hopper 2, and the bottom outlet of the auxiliary material bin 28 is provided with a coating wheel 202 that can roll on the lower upper roller 3. Two sets of push rod assemblies 9 are arranged in parallel and the top ends are respectively abutted against the movable cover 7 and the bottom of the cantilever end of the auxiliary material bin 28. When the push rod assembly 9 pushes the movable cover 7 upward, the movable cover 7 swings a certain angle around the pin screw 3 601, and the coating wheel 1 701 is separated from the upper roller 3. The push rod assembly 9 pushes the auxiliary material bin 28 upward, and the auxiliary material bin 28 swings a certain angle around the pin screw 203, and the coating wheel 202 is separated from the upper roller 3.

[0042] Through the setting of the push rod assembly 9, only when the lower discharge cut-off plate 10 is disassembled, the bottom end of the push rod assembly 9 contacts the slide rail 101, and the push rod assembly 9 moves downward as a whole, so that the cantilever ends of the movable cover 7 and the auxiliary material bin 2 8 swing downward, and the coating wheel 1 701 and the coating wheel 2 802 respectively roll in contact with the corresponding upper rollers 3, so that the auxiliary materials can be transferred from the bin to the upper rollers 3. That is, when the lower discharge cut-off plate 10 is disassembled, the adjustable pressing roller group 4 can be discharged to the cutting roller group 5 for cutting, which ensures the mechanical interlocking. When the lower discharge cut-off plate 10 is installed, only pressing can be performed, and cutting cannot be performed.

[0043] In a specific embodiment of the present invention, Figures 1 to 3 As shown, the auxiliary material bin 6 is integrally formed on the bottom surface of the hopper 2, and the bottom wall of the hopper 2 is provided with an auxiliary material bin inlet 201 above the auxiliary material bin 6.

[0044] Specifically, the hopper 2 is made of transparent high-density polyethylene or polypropylene, which is convenient for observing the remaining material in the auxiliary material bin 6.

[0045] Specifically, if Figure 3As shown, the bottom side wall of the auxiliary material bin 6 is set as a spring sheet 602, the middle and bottom end of the spring sheet 602 are separated from the side wall of the auxiliary material bin 6, and the discharge port of the auxiliary material bin 6 is opened between the bottom wall and the spring sheet 602; when the top end of the push rod assembly 9 abuts against the bottom of the cantilever end of the movable cover 7, the coating wheel 701 presses the spring sheet 602 to close the discharge port of the auxiliary material bin 6.

[0046] By integrally forming the auxiliary material bin 6 on the bottom surface of the hopper 2, the bottom wall of the hopper 2 is used as the top wall of the auxiliary material bin 6, eliminating the need for a separate bracket, and making the structure more sophisticated; by using a transparent material to make the hopper 2, it is easy to observe the remaining material in the auxiliary material bin 6 and the amount of material discharged. By adding a spring sheet 602 above the discharge port of the auxiliary material bin 6, the spring sheet 602 is pressed to close the discharge port of the auxiliary material bin 6 when the coating wheel 701 is lifted, thereby reducing the leakage of the auxiliary material bin 6 downward during the noodle pressing process.

[0047] In a specific embodiment of the present invention, Figure 1 , Figure 2 and 4 As shown, the cross section of the auxiliary material bin 28 is a triangular profile bin body, and the auxiliary material bin 2 inlet 801 is provided at the upper position of the top wall of the auxiliary material bin 28. The auxiliary material bin 2 inlet 801 is provided at a position close to the pin screw 203. The corresponding side wall above the coating wheel 202 is provided with a spring sheet 203, and the side of the spring sheet 203 is separated from the side wall of the auxiliary material bin 28, that is, the end facing the coating wheel 202 is a cantilever elastic end. The discharge port of the auxiliary material bin 28 is provided between the bottom edge of the spring sheet 203 and the coating wheel 202. A top block 204 is provided on the inner side wall of the hopper 2, and the top block 204 is in an L shape with its head facing the spring sheet 203. The root of the top block 204 is integrally fixedly connected to the hopper 2. When the top end of the top rod assembly 9 abuts against the bottom of the cantilever end of the auxiliary material bin 28, the top block 204 presses the spring sheet 203 to close the discharge port of the auxiliary material bin 28.

[0048] By opening the auxiliary material bin second inlet 801, it is convenient to add auxiliary materials into the inner cavity of the auxiliary material bin second 8, and it is also convenient to observe the internal material conditions; through the cooperation of the top block 204 and the spring piece 2 803, when the auxiliary material bin second 8 is lifted by the push rod assembly 9, the discharge port of the auxiliary material bin second 8 can be closed to avoid material leakage downward during the dough pressing process.

[0049] In a specific embodiment of the present invention, Figure 1 , Figure 2 and Figure 5As shown, the push rod assembly 9 includes a main rod body 901 and a roller end 903. The cross section of the main rod body 901 is an equilateral polygonal profile. In a specific embodiment, the cross section of the main rod body 901 is a square. The main rod body 901 is vertically guided and connected to the inner wall of the side plate of the frame 1 through a plurality of matching guide sleeves 102. The upper and lower ends of the main rod body 901 are respectively fixedly connected to the roller end 903, and the roller of the roller end 903 rolls in contact with any one of the slide rail 101, the lower discharge cut-off plate 10, the movable cover 7 and the auxiliary material bin 8.

[0050] By adopting an equilateral polygonal profile as the guide cross-sectional profile, the roller end 903 can be prevented from rotating along with the main rod body 901, thereby ensuring that the roller is always rolled and lifted along the set direction; by adding a roller end 903 to the main rod body 901, rolling friction is used instead of sliding friction, thereby reducing frictional resistance and facilitating smooth lifting.

[0051] Specifically, if Figure 1 , Figure 2 and Figure 5 As shown, the push rod assembly 9 also includes a threaded section 902 and a double threaded sleeve 904. The middle of the main rod body 901 is disconnected and the rod at the disconnected portion is provided with a coaxial threaded section 902. The two opposite threaded sections 902 have opposite threaded directions. The double threaded sleeve 904 is threadedly connected between the two opposite threaded sections 902.

[0052] Specifically, if Figure 5 As shown, a wrench platform 905 is provided in the middle of the outer wall of the double-threaded sleeve 904, and the distance between opposite sides of the wrench platform 905 corresponds to that of an open-end wrench.

[0053] By adding a threaded section 902 with opposite thread rotation directions and a double threaded sleeve 904 in the middle of the main rod body 901, the length of the main rod body 901 can be adjusted, and the height of the lifting cover 7 and the auxiliary material bin 8 of the top rod assembly 9 can be adjusted, so as to better close the corresponding discharge port. By adding a wrench platform 905 in the middle of the double threaded sleeve 904, it is convenient to use an open-end wrench for adjustment.

[0054] The working process of the fresh noodle preparation equipment of the present invention is as follows: when pressing noodles, the dough or noodle flocculants are placed on the hopper 2, and the equipment starts the upper roller 3, the adjustable noodle pressing roller group 4 and the noodle cutting roller group 5 to start running. At this time, the lower discharge cut-off plate 10 is installed, and the lower discharge cut-off plate 10 separates the noodle cutting roller group 5. At the same time, the roller end 903 at the bottom end of the push rod assembly 9 abuts against the top surface of the lower discharge cut-off plate 10, and the roller end 903 at the top pushes the movable cover 7 and the auxiliary material bin 2 8 to the high position. The coating wheel 1 701 presses the spring sheet 1 602 to close the discharge port of the auxiliary material bin 1 6; the top block 204 presses the spring sheet 2 803 to close the discharge port of the auxiliary material bin 2 8. Manually and slowly feed the dough or noodle flocculants, the dough or noodle flocculants are first rolled by the two upper rollers 3, and then rolled downward by the adjustable noodle pressing roller group 4 for the second time, and then fall onto the horizontal plate of the lower discharge cut-off plate 10. After taking out the pressed noodles, fold them and put them into the hopper 2 again, press them repeatedly until continuous noodles of roughly equal width are formed, and then stop the equipment. To prepare for cutting noodles, first remove the screws between the lower discharge plate 10 and the frame 1, and remove the lower discharge plate 10. At this time, the roller end 903 at the bottom of the top rod assembly 9 moves downward and abuts against the slide rail 101, and the roller end 903 at the top lowers the movable cover 7 and the auxiliary material bin 2 8 to a low position, and the coating wheel 1 701 and the coating wheel 2 802 are respectively in contact with the corresponding upper roller 3. The equipment starts the upper roller 3, the adjustable pressing roller group 4 and the cutting roller group 5 to start running and cut noodles. The above complete dough sheet is placed on the hopper 2 and one end is put into the feeding port between the two upper rollers 3. During the initial rolling process of the two upper rollers 3, the coating wheel 1 701 and the coating wheel 2 802 respectively roll and contact with the corresponding upper rollers 3, and the auxiliary materials are transferred from the silo to the upper rollers 3. The upper rollers 3 roll and coat the auxiliary materials at the same time, which can completely and evenly coat the entire large side surface, and the applied pressure can ensure that the auxiliary materials are half embedded in the noodles and are not easy to fall off. After the secondary rolling by the adjustable noodle pressing roller group 4, it falls into the cutting roller group 5 for cutting, and finally the noodles are removed from the bottom of the equipment.

[0055] In summary, the fresh noodle preparation equipment of the present invention, by adding auxiliary material bin 1 6 and auxiliary material bin 2 8 for storing the auxiliary materials above the upper roller 3, the auxiliary material bin 1 6 and auxiliary material bin 2 8 continuously supply auxiliary materials to the upper roller 3 during cutting, and the upper roller 3 is used to apply the auxiliary materials while pressing the dough sheet, so that the auxiliary materials can be evenly applied on the two large sides of the dough sheet. At the same time, the upper roller 3 applies the auxiliary materials while rolling, and the applied pressure can ensure that the auxiliary materials are half-embedded in the noodles, not easy to fall off, and the adhesion effect is good. In addition, through the setting of the top rod assembly 9, only when the lower discharge cut plate 10 is disassembled, the bottom end of the top rod assembly 9 contacts the slide rail 101, and the top rod assembly 9 moves downward as a whole, so that the cantilever ends of the movable cover 7 and the auxiliary material bin 2 8 are both swung downward, and the coating wheel 1 701 and the coating wheel 2 802 are respectively in rolling contact with the corresponding upper roller 3, so that the auxiliary materials can be transferred from the material bin to the upper roller 3. That is, when the lower discharge cut-off plate 10 is disassembled, the adjustable noodle pressing roller set 4 can be discharged to the noodle cutting roller set 5 for noodle cutting, which ensures the mechanical interlocking. When the lower discharge cut-off plate 10 is installed, only noodle pressing can be performed, and noodle cutting cannot be performed. By integrally forming the auxiliary material bin 6 on the bottom surface of the hopper 2, the bottom wall of the hopper 2 is used as the top wall of the auxiliary material bin 6, eliminating the need for a separate bracket, and making the structure more sophisticated; by using a transparent material to make the hopper 2, it is easy to observe the remaining material and the amount of material discharged in the auxiliary material bin 6. By adding a spring sheet 602 above the discharge port of the auxiliary material bin 6, the spring sheet 602 is pressed to close the discharge port of the auxiliary material bin 6 when the coating wheel 701 is lifted, thereby reducing the leakage of the auxiliary material bin 6 downward during the noodle pressing process. By opening the auxiliary material bin second inlet 801, it is convenient to add auxiliary materials to the inner cavity of the auxiliary material bin second 8, and it is also convenient to observe the internal material conditions; through the cooperation of the top block 204 and the second spring piece 803, when the auxiliary material bin second 8 is lifted by the top rod assembly 9, the discharge port of the auxiliary material bin second 8 can be closed to avoid material leakage downward during the pressing process. By using an equilateral polygon profile as the guide cross-sectional profile, it is possible to prevent the roller end 903 from rotating with the main rod body 901, ensuring that the roller is always rolling and lifting along the set direction; by adding a roller end 903 to the main rod body 901, rolling friction is used instead of sliding friction, reducing friction resistance, and facilitating smooth lifting. By adding a threaded section 902 with opposite thread rotation directions and a double-threaded sleeve 904 in the middle of the main rod body 901, the length of the main rod body 901 is adjustable, and then the height of the top rod assembly 9 lifting the movable cover 7 and the auxiliary material bin second 8 is adjustable, so as to achieve better closing of the corresponding discharge port. By adding a wrench platform 905 in the middle of the double-threaded sleeve 904, it is convenient to use an open-end wrench for adjustment.
