Description

Technical Field

[0001] The invention belongs to the technical field of food detection, and in particular relates to a method and equipment for detecting quality of baked products. Background Art

[0002] The shape of baked products is usually a relatively regular block, so as to avoid local burning. During the baking process, the dough is placed on the grill, heated up and down, and baked to obtain the baked product. The internal and external temperatures of the baked product are inconsistent, so the outside is usually ripened before the inside. The time and temperature required for baking the baked product are affected by factors such as the ratio of ingredients, size, and water content. It is necessary to undergo multiple tests to obtain the optimal baking temperature and baking time suitable for the baked product so that the baked product can obtain the best state. Therefore, it is necessary to test the baked product obtained by the test. The appearance of the baked product can be obtained by observation, while the temperature and humidity of the interior, especially the center, are crucial to whether it meets the standards. The traditional detection method is to manually break the baked product apart, roughly determine the center, and then take samples for detection, but this method has a large error. Therefore, how to quickly and accurately detect the same part of the baked product and provide guidance for the baking temperature and baking time of the baked product is a problem that technicians in this field need to solve. Summary of the invention

[0003] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a method and equipment for inspecting the quality of baked products, which can quickly determine the height and the height of the center of the baked products, so that the sampling component can quickly and accurately reach the center of the baked products for inspection or sampling, unify the inspection position of the baked products, and provide effective guidance for the selection of baking temperature and baking time of the baked products.

[0008] S3. Select a sampling component and insert the sampling component into the center of the baked product for sampling.

[0009] A baked product quality inspection device is used to implement a baked product quality inspection method. The device includes a fixed frame, height-fixing splints and a centering sampling device respectively arranged on the fixed frame. The height-fixing splints include a bottom plate, a top plate and a group of brackets. The brackets are respectively hinged in pairs by means of hinged rods. The bottom plate is connected to the top plate by means of mutually hinged brackets. The hinged rods are at the same vertical distance from the bottom plate and the top plate. Sampling holes are arranged on the top plate or the bottom plate. The centering sampling device includes a depth limiting plate and a sampling component. The end of the depth limiting plate contacts the hinged rod to form a depth limiting mechanism of the sampling component.

[0010] The brackets are hinged in pairs to form a V-shaped structure, and the ends of the two brackets are hinged to the bottom plate and the top plate respectively. The ends of the hinged rods extend outward from the brackets and contact the ends of the depth limiting plates to form a depth limiting mechanism of the sampling component.

[0011] The centering sampling device also includes a rotating disk, and the rotating disk and the depth limiting plate are respectively connected to the fixed frame. The sampling component is arranged on the rotating disk with the help of a second telescopic rod. The rotating disk and the sampling through-hole are eccentrically arranged. The sampling component is aligned with the sampling through-hole in sequence with the help of the rotation of the rotating disk. The sampling component has the freedom of lifting and lowering through the sampling through-hole with the help of the second telescopic rod.

[0012] The height-fixing splint also includes a first telescopic rod, the fixed end of the first telescopic rod is connected to the fixed frame, and the telescopic end of the first telescopic rod is connected to the bottom plate. With the help of the first telescopic rod, the height-fixing splint has the freedom to rise and fall relative to the centering sampling device. A sampling through hole is provided on the top plate, and the centering sampling device is located above the top plate.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0024] Specific embodiment, this embodiment relates to a method for detecting the quality of baked products, comprising the following steps:

[0025] S1, selecting a baked product 1; setting a number of combinations of different baking temperatures and baking times, and testing the baked product 1 obtained after baking under each combination of conditions;

[0026] S2, measuring the height of the baked product 1, and determining the height of the central part of the baked product 1;

[0027] S3. Select the sampling component 12 and insert the sampling component 12 into the central part of the baked product 1 for sampling and detection.

[0028] like Figure 1-3 As shown, a baked product quality inspection device is used to implement a baked product quality inspection method, comprising a fixed frame 2, a height-fixing clamp plate 3 respectively arranged on the fixed frame 2, a centering sampling device 4 and a first telescopic rod 5, wherein the height-fixing clamp plate 3 and the centering sampling device 4 have a relative degree of freedom of lifting and lowering by means of the first telescopic rod 5, the height-fixing clamp plate 3 comprises a bottom plate 6, a top plate 7 and a group of brackets 8, the brackets 8 are respectively hinged in pairs by means of hinged rods 9, the bottom plate 6 is connected to the top plate 7 by means of the mutually hinged brackets 8, the hinged rod 9 is at the same vertical distance from the bottom plate 6 and the top plate 7, a sampling through hole 10 is arranged on the top plate 7 or the bottom plate 6, the centering sampling device 4 comprises a depth-limiting plate 11 and a sampling component 12, the end of the depth-limiting plate 11 contacts the hinged rod 9 to form a depth-limiting mechanism of the sampling component 12. The hinged rod 9 is provided with an auxiliary depth-limiting switch matched with the depth-limiting plate 11, and the auxiliary depth-limiting switch is used to control the first telescopic rod 5. When the depth limit plate 11 contacts the hinged rod 9 , the depth limit plate 11 touches the auxiliary depth limit switch, and the first telescopic rod 5 stops extending.

[0029] During inspection, the top plate 7 is raised to provide sufficient placement space for the baked product 1 between the top plate 7 and the bottom plate 6; then, the baked product 1 is placed on the bottom plate 6, and the top plate 7 is moved downward until it contacts the upper surface of the baked product 1, and the distance between the top plate 7 and the bottom plate 6 is the height of the baked product 1; the brackets 8 are hinged in pairs by means of hinged rods 9 and the bottom plate 6 is connected to the top plate 7 by means of the mutually hinged brackets 8, so that the vertical distance between the hinged rod 9 and the bottom plate 6 and the top plate 7 is always the same, so when the top plate 7 contacts the upper surface of the baked product 1, the height of the hinged rod 9 is the height of the center of the baked product 1, and the height of the center of the baked product 1 can be quickly determined accurately and reliably through the connection between the bracket 8 and the hinged rod 9 and the connection between the bracket 8 and the top plate 7 and the bottom plate 6. The depth limit plate 11 or the height setting clamp plate 3 moves in the vertical direction. In this embodiment, the height setting clamp plate 3 moves until the end of the depth limit plate 11 contacts the hinge rod 9. The moving distance of the sampling component 12 can be obtained according to the moving distance of the depth limit plate 11. Preferably, the positions of the depth limit plate 11 and the sampling component 12 are fixed, and the sampling component 12 and the end of the depth limit plate 11 are located at the same height. The height setting clamp plate 3 moves synchronously relative to the depth limit plate 11 and the sampling component 12. When the depth limit plate 11 contacts the hinge rod 9, the sampling component 12 reaches the height of the center of the baked product 1, making the detection process convenient and quick.

[0030] Further, such as Figure 1 , Figure 3As shown, the brackets 8 are hinged in pairs to form a V-shaped structure, and the ends of the two brackets 8 are hinged to the bottom plate 6 and the top plate 7 respectively. The ends of the hinged rods 9 extend outward from the brackets 8 and contact the ends of the depth limiting plates 11 to form a depth limiting mechanism of the sampling component 12. The brackets 8 have the same length, and the left and right sides of the bottom plate 6 are connected to the top plate 7 by means of the brackets 8 hinged to each other in a V-shaped structure. The connection structure of the brackets 8 with the bottom plate 6 and the top plate 7 in the V-shaped hinged manner is simple. The top plate 7 can be raised by pulling up, and the top plate 7 can be vertically dropped to the upper surface of the baked product 1 under the action of its own gravity when the top plate 7 is released.

[0031] Furthermore, the centering sampling device 4 also includes a rotating disk 13, and the rotating disk 13 and the depth limit plate 11 are respectively connected to the fixed frame 2. The sampling component 12 is arranged on the rotating disk 13 with the help of a second telescopic rod 14. The rotating disk 13 and the sampling hole 10 are eccentrically arranged. The sampling component 12 is aligned with the sampling hole 10 in sequence with the help of the rotation of the rotating disk 13. The sampling component 12 has the freedom to rise and fall through the sampling hole 10 with the help of the second telescopic rod 14.

[0032] In this embodiment, the sampling components 12 on the rotating disk 13 are respectively a sampling tube, a temperature sensor and a humidity sensor. The sampling component 12 working in conjunction with the depth limit plate 11 is one of the sampling tube, the temperature sensor and the humidity sensor, and the sampling component 12 is selected according to the actual detection items.

[0033] In the initial state, the second telescopic rod 14 is in a retracted state. During the test, the rotating disk 13 rotates, and the sampling component 12 is selected to be located above the sampling hole 10 according to the required test items. Then, the second telescopic rod 14 connected to the sampling component 12 is extended so that the sampling component 12 and the end of the depth limit plate 11 are at the same height. The extended length of the second telescopic rod 14 is a preset fixed length. The sampling component 12 and the depth limit plate 11 can be selected according to different test items for matching and setting for sampling and testing.

[0034] Furthermore, the fixed end of the first telescopic rod 5 is connected to the fixed frame 2, and the telescopic end of the first telescopic rod 5 is connected to the bottom plate 6. The height-fixing clamping plate 3 has the freedom to rise and fall relative to the centering sampling device 4 by means of the first telescopic rod 5. The top plate 7 is provided with a sampling hole 10, and the centering sampling device 4 is located above the top plate 7. After the top plate 7 contacts the upper surface of the baked product 1, the telescopic end of the first telescopic rod 5 extends to lift the height-fixing clamping plate 3 and move it toward the centering sampling device 4.

[0035] In this embodiment, the depth limit plate 11 is an inverted T-shaped plate, and the horizontal end of the T-shaped plate contacts the hinged rod 9 to form a depth limit mechanism of the sampling component 12. Since the heights of the baked products 1 are inconsistent, the positions of the hinged rod 9 on the horizontal plane are different. The horizontal end of the T-shaped plate has a wide coverage range, which can ensure that the depth limit plate 11 can be adapted to baked products 1 of different heights while using less material, thereby saving the manufacturing cost of the detection equipment.

[0036] Preferably, Figure 1 , Figure 3 , Figure 4 As shown, a horizontal centering assembly 15 is provided on the bottom plate 6, and the horizontal centering assembly 15 includes a pair of double-headed screws 16 and a set of push plates 17. The double-headed screw 16 is rotatably provided on the bottom plate 6, and the two ends of the double-headed screw 16 are respectively provided with positive threads and negative threads. The push plates 17 are respectively provided at the two ends of the double-headed screw 16 and are threadedly connected with the double-headed screw 16. The double-headed screws 16 are arranged in a cross-shaped manner, and the intersection is coaxially arranged with the sampling hole 10. The bottom plate 6 is provided with a guide slide hole 18 matched with the push plates 17. In the initial position, the two push plates 17 on the double-headed screw 16 are at the same distance from the intersection.

[0037] After placing the baked product 1 on the bottom plate 6, the two double-headed screws 16 are rotated respectively to make the push plates 17 on each double-headed screw 16 move toward each other. The push plates 17 push the baked product 1 until the baked product 1 is in contact with the push plates 17 on the double-headed screw 16, ensuring that the center of the baked product 1 is located on the axis of the sampling through hole 10, thereby improving the selection accuracy of the center of the baked product 1.
