Description

Technical Field

[0001] The present invention relates to the technical field of hard cheese production, and particularly to a hard cheese production device and method thereof. Background Art

[0002] Hard cheese is a dairy product. Hard cheese is large and thick, and its unique heavy sweetness takes a long time to mature.

[0003] In the related art, the industrial production process of hard cheese is as follows: First, the milk needs to be pasteurized. After sterilization, rennet is added to the warm milk, and it is stirred in a cheese emulsification and stirring tank to separate the milk fat and water in the milk, so that the protein in the milk gradually forms curds. After about 30 minutes, when the milk starts to solidify, the milk body is stirred into wheat grain shape, and the texture of the curd will become quite soft to obtain a good curd mass. The liquid in the milk body is filtered out to obtain dry cheese particles. The cheese particles are fully crushed by a crusher, and the cheese particles are extruded to form a semi-finished cheese product. Then, the semi-finished cheese product is pressed into a cheese block by a mold and dried to form hard cheese.

[0004] However, since the quality of milk is greatly affected by the milk source, the milk fat rate, milk protein, and somatic cell count in the milk directly determine the quality of milk, and the milk fat content depends on the feeding process of dairy cows. Therefore, there are also differences in the quality of milk provided by the same milk source at different times.

[0005] Therefore, when the quality of the milk from the milk source fluctuates, the emulsification treatment process of stirring and heating the milk added with rennet at a preset time and preset temperature cannot further meet the production quality control requirements of cheese.

[0057] The inventive concept of the present invention will be further elaborated below in conjunction with some specific embodiments.

[0058] The present invention provides a hard cheese production device.

[0059] Refer to Figure 1 and Figure 2 , Figure 1 which are the overall structural schematic diagrams of the hard cheese production device of the present invention, Figure 2 and which are the schematic diagrams of the use state of the hard cheese production device of the present invention.

[0060] In an embodiment of the present invention, as shown in Figure 1 and Figure 2 , a hard cheese production device includes a bearing assembly 100, a sampling mechanism 200, an image acquisition unit 300, and a main control module 400. The bearing assembly 100 is detachably arranged in an external cheese emulsification and stirring tank; the cheese emulsification and stirring tank includes a stirring mechanism 800; the sampling mechanism 200 is rotatably arranged on the bearing assembly 100. A standard color card 500 and a plurality of sampling color cards 600 are annularly distributed around the sampling mechanism 200. The sampling color cards 600 are used to contact and collect milk samples in the cheese emulsification and stirring tank; the image acquisition end of the image acquisition unit 300 faces and corresponds to one side of the sampling mechanism 200, and is used to acquire the image of the standard color card 500 and the image of the sampling color card 600; the image of the standard color card 500 includes standard color information, and the image of the sampling color card 600 includes the color information of the milk sample; the main control module 400 is electrically connected to the stirring mechanism 800, the image acquisition unit 300, and the sampling mechanism 200 respectively, and is used to obtain the standard color information and the color information of the milk sample. The main control module 400 compares the obtained standard color information and the color information of the milk sample, and outputs corresponding command signals.

[0061] For ease of understanding, a specific embodiment is shown below:

[0062] Hang the bearing assembly 100 on the side wall 700 of the external cheese emulsification and stirring tank, so that the sampling mechanism 200 is located in the cheese emulsification and stirring tank, and each sampling color card 600 on the sampling mechanism 200 can contact the milk in the cheese emulsification and stirring tank during the sampling process, so as to adsorb the liquid separated from the milk on the sampling color card 600.

[0063] Before the stirring mechanism 800 stirs the milk added with rennet in the cheese emulsification stirring tank, according to the color of the hard cheese to be prepared, a matching standard color card 500 is selected, and the standard color card 500 is installed on the stirring mechanism 800. The image acquisition unit 300 acquires an image of the standard color card 500, and sends the image color of the standard color card 500 to the main control module 400.

[0064] When the stirring mechanism 800 stirs the milk added with rennet in the cheese emulsification stirring tank, after a certain time, such as 15 minutes, the sampling mechanism 200 is started, and the liquid separated from the milk body is adsorbed on the sampling color card 600. The image acquisition unit 300 acquires an image of the sampling color card 600 carrying the milk body again, and sends the image color of the sampling color card 600 to the main control module 400.

[0065] The main control module 400 compares the image color of the standard color card 500 with the image color of the sampling color card 600, and outputs the comparison result.

[0066] The main control module 400 controls the start and stop of the stirring mechanism 800, the start and stop of the sampling mechanism 200, and the start and stop of the image acquisition unit 300 according to the comparison result.

[0067] The technical solution of the present invention drives the sampling color card 600 through the sampling mechanism 200 to sample the milk body liquid formed by the milk added with rennet during the stirring process, and uses the standard color card 500 to compare the color with the sampling color card 600 carrying the milk body, so as to obtain the separation degree of the milk fat in the milk body, which can further meet the production quality control requirements of cheese, improve the finished product quality of hard cheese, and by adjusting different standard color cards 500, it can meet the production requirements of different types of cheese.

[0068] Continue to refer to Figure 2 。

[0069] Further, as Figure 2 shown, to facilitate increasing the adaptability and installation convenience of the bearing component 100, the cheese emulsification stirring tank includes a box body side wall 700; the bearing component 100 includes a hanging plate 110 and a bearing plate 120. One end of the hanging plate 110 is bent downward to form a bent portion 111 and an installation groove 112 for inserting the box body side wall 700, and the bearing plate 120 is arranged on the bent portion 111.

[0070] It should be noted that Figure 2 the up and down direction of

[0071] Continue to refer to Figure 1 and Figure 2 ,and refer to Figure 3 , Figure 3Schematic diagram of the installation structure of the sampling mechanism 200 according to the present invention.

[0072] Further, to facilitate the encapsulation of the sampling mechanism 200 and prevent the sampling mechanism 200 from contacting too much steam in the milk body, thereby reducing the service life of the sampling mechanism 200, a strip-shaped opening 121 is formed on the bearing plate 120. Two spaced-apart frames 122 are also provided on the bearing plate 120, and the strip-shaped opening 121 is disposed between the two frames 122; the sampling mechanism 200 includes a turntable 210, a rotating shaft 220, and a driving motor 230. The turntable 210 is vertically disposed in the strip-shaped opening 121. The turntable 210 is sleeved around the rotating shaft 220. The two ends of the rotating shaft 220 are respectively rotatably connected to the two frames 122. The output shaft of the driving motor 230 is connected to one end of the rotating shaft 220 to drive the rotating shaft 220 to rotate and drive the turntable 210 to rotate in the strip-shaped opening 121. While the turntable 210 rotates, it drives the standard color card 500 and the sampling color card 600 to rotate, so that the sampling color card 600 contacts the milk body in the cheese emulsification and stirring tank.

[0073] It should be noted that a housing for encapsulating the bearing plate 120 and various mechanisms and modules on the bearing plate 120 is also provided on the bearing plate 120, and the driving motor 230 is a servo motor or a stepper motor.

[0074] It should be understood that the bearing plate 120 is located inside the cheese emulsification and stirring tank and at the top of the cheese emulsification and stirring tank. After the bearing plate 120 is installed, only the standard color card 500 or the sampling color card 600 outside the turntable 210 can contact the milk liquid level in the cheese emulsification and stirring tank.

[0075] As another option of this embodiment, the sampling mechanism 200 is disposed at the edge of the bearing plate 120, so that the standard color card 500 or the sampling color card 600 disposed outside the sampling mechanism 200 can contact the milk body liquid in the cheese emulsification and stirring tank.

[0076] Continue to refer to Figures 1 to 3 , and refer to Figure 4 , Figure 4 Schematic diagram of the structures of the standard color card 500 and the sampling color card 600 according to the present invention.

[0077] Further, as Figures 1 to 4 shown, a first mounting hole is formed on the turntable 210; to facilitate the image acquisition unit 300 to sample the image of the standard color card 500, the standard color card 500 includes a standard color piece 520 and a transparent first card sleeve 510. The first card sleeve 510 is sleeved around the standard color piece 520. One end of the first card sleeve 510 is provided with a first connecting column, and the first connecting column is inserted into the first mounting hole.

[0078] It should be noted that the material of the transparent first card sleeve 510 is glass or transparent plastic; for the convenience of installing the standard color card 500, the first connecting column is a threaded column, the inner wall of the first mounting hole is formed with a thread adapted to the first connecting column, and the second mounting column is in threaded fit with the first mounting hole.

[0079] Furthermore, for the convenience of setting the number of sampling color cards 600 according to the sampling period, and for the convenience of improving the sampling accuracy of the sampling color card 600 and preventing the liquids of the milk bodies carried on two adjacent sampling color cards 600 from being mutually contaminated, a plurality of second mounting holes are formed on the turntable 210, and the plurality of second mounting holes and the first mounting hole are annularly distributed along the circumferential direction of the turntable 210; for the convenience of the image acquisition unit 300 sampling the image of the sampling assembly 610 to display the color of the milk body liquid carried by the sampling assembly 610, the sampling color card 600 includes a sampling assembly 610 and a transparent second card sleeve 620, the second card sleeve 620 is sleeved on the periphery of the sampling assembly 610, one end of the second card sleeve 620 is provided with a second connecting column, and the second connecting column is inserted into the second mounting hole.

[0080] It should be noted that the material of the transparent second card sleeve 620 is glass or transparent plastic; for the convenience of installing the sampling color card 600, the second connecting column is a threaded column, the inner wall of the second mounting hole is formed with a thread adapted to the second connecting column, and the second mounting column is in threaded fit with the second mounting hole.

[0081] Continue to refer to Figure 4 and refer to Figure 5 Figure 5 which is a schematic structural diagram of the sampling assembly 610 involved in the present invention.

[0082] Furthermore, the sampling assembly 610 includes side plates 611 and a water absorption sheet 612. Side plates 611 are provided on both sides of the water absorption sheet 612. Concave grooves for the side plates 611 to be inserted and fitted are formed on the inner side walls of the two opposite sides of the second card sleeve 620. The water absorption sheet 612 is used to contact and collect the milk body sample in the cheese emulsification and stirring tank.

[0083] It should be noted that the water absorption sheet 612 includes a coating layer and a lining. The coating layer is coated on the periphery of the lining. After the coating layer comes into contact with the liquid in the milk body, in order to more favorably adsorb the liquid in the milk body and develop the color of the liquid in the milk body, the coating layer is any one of a white polyester fiber water absorption cotton sheet, a PVA water absorption sponge sheet, a white felt cloth sheet, a plant fiber water absorption cotton sheet or a PET water absorption cotton sheet.

[0084] It should be understood that the side plates 611 are made of a hard material such as plastic, stainless steel, etc. Concave grooves for installing the water absorption sheet 612 are formed on the two opposite sides of the two side plates 611 facing each other. The water absorption sheet 612 is inserted into the grooves to connect the two side plates 611 to the opposite sides of the water absorption sheet 612.​

[0085] Continue to refer to Figure 1 and Figure 2 and refer to Figure 6 , Figure 6 is a block diagram of the structures of the image acquisition unit 300, main control module 400, sampling mechanism 200, and stirring mechanism 800 according to the present invention.

[0086] Furthermore, Figure 1 , Figure 2 and Figure 6 As shown, the image acquisition unit 300 includes a camera module 310 and a storage module 320. The camera module 310 is disposed on the carrier board 120. The image acquisition end of the camera module 310 faces and corresponds to one side of the turntable 210, and is used to acquire images of the standard color chip 520 and the water absorption sheet 612. The signal input end of the storage module 320 is electrically connected to the signal output end of the camera module 310, and is used to receive and store the images of the standard color chip 520 and the water absorption sheet 612.

[0087] It should be noted that in Figure 6 , the white arrow indicates the transmission direction of the image color information of the standard color card 500 and the image color information of the sampling color card 600 carrying the milk body, and the black arrow indicates the transmission direction of the control signal of the main control module 400 to the camera module 310, the transmission direction of the control signal to the stirring mechanism 800, and the transmission direction of the control signal to the sampling mechanism 200.

[0088] It should be understood that the camera module 310 includes a camera for photographing the standard color card 500 and the sampling color card 600. The camera is disposed facing and corresponding to one side of the turntable 210. The shooting range of the camera can only cover one standard color card 500 or one sampling color card 600. That is, in each image acquisition process, the camera can only shoot an image of one standard color chip 520 or an image of a water absorption sheet 612 carrying a milk body sample. When using the camera for shooting, by driving the turntable 210 to rotate by the driving motor 230, the turntable 210 drives the standard color card 500 or the sampling color card 600 to rotate, thereby changing the relative position between the standard color card 500 or the sampling color card 600 and the camera, so as to move the standard color card 500 out of or into the shooting range of the camera, or move the sampling color card 600 out of or into the shooting range of the camera.

[0089] Further, the signal input end of the main control module 400 is electrically connected to the signal output end of the storage module 320. The first signal output end of the main control module 400 is electrically connected to the signal input end of the stirring mechanism 800. The second signal output end of the main control module 400 is electrically connected to the signal input end of the sampling mechanism 200. The third signal output end of the main control module 400 is electrically connected to the signal input end of the image acquisition unit 300. The main control module 400 is used for controlling the start and stop of the stirring mechanism 800, the start and stop of the sampling mechanism 200, and the start and stop of the image acquisition unit 300, and correspondingly outputs command signals.

[0090] It should be noted that the image acquisition unit 300 includes a camera module 310 and a storage module 320. The signal output end of the camera module 310 is electrically connected to the signal input end of the storage module 320. The signal output end of the camera module 310 respectively sends the images of the standard color card 500 and the sampling color card 600 collected by it to the storage module 320. The image acquisition unit 300 is electrically connected to the main control module 400. The signal output end of the storage module 320 is electrically connected to the signal input end of the main control module 400, so as to sequentially and respectively send the images of the standard color card 500 and the sampling color card 600 to the main control module 400. The main control module 400 compares the images of the standard color card 500 and the sampling color card 600, and outputs a comparison result. The comparison result is the color difference ∆E between the color of the image of the standard color card 500 and the color of the image of the sampling color card 600.

[0091] It should be understood that the circuit logic of the image acquisition unit 300 and the main control module 400, as well as the algorithm logic for the main control module 400 to compare the images of the standard color card 500 and the sampled color card 600, can refer to the colorimeters (color difference meters) available on the market. The colorimeters (color difference meters) are the latest type of portable color difference meters developed and produced in accordance with relevant international standards such as CIE1931 and 1976, and the national standard JJG595-2002. According to the type of photosensor, they can be divided into tristimulus color difference meters and spectrophotometric color difference meters; according to volume and usage scenarios, they can be further divided into handheld color difference meters, desktop color difference meters, and portable color difference meters. According to the measurement geometric structure, they can be divided into 8° / d, d / 8°, 45° / 0, etc., and whether they include specular reflection or not. The colorimeter can automatically compare the color difference between the sample (standard color card 500) and the tested product (sampled color card 600), and output three groups of data of CIE L, a, b and four groups of color difference data of ∆E, ∆L, ∆a and ∆b after color comparison. According to the data results displayed after color measurement by the colorimeter, the following analysis is carried out: ∆E is the magnitude of the total color difference between the sample (standard color card 500) and the tested product (sampled color card 600), ∆E = [(∆L) + (∆a) + (∆b)] * 1 / 2, ∆L = Lsample - Lstandard (brightness difference), ∆a = asample - astandard (red / green difference), ∆b = bsample - bstandard (yellow / blue difference), ∆L+ indicates a tendency towards white, ∆L- indicates a tendency towards black, ∆a+ indicates a tendency towards red, ∆a- indicates a tendency towards green, ∆b+ indicates a tendency towards yellow, and ∆b- indicates a tendency towards blue.

[0092] It should be noted that the image acquisition unit 300 (camera module 310 and storage module 320), the main control module 400, the sampling mechanism 200, the stirring mechanism 800, the drive motor 230, etc. in this solution are all common circuits or physical objects in the prior art. The innovation of this solution does not lie in a single circuit, but in the coordinated use of several modules and circuits to achieve the purpose of image acquisition of the standard color card 500 and the sampled color card 600 carrying milk, storing the image colors of the standard color card 500 and the sampled color card 600, transmitting the image colors of the standard color card 500 and the sampled color card 600 to the main control module 400, the main control module 400 comparing the image colors of the standard color card 500 and the sampled color card 600 and outputting the comparison result, the main control module 400 controlling the start and stop of the camera module 310, the main control module 400 controlling the start and stop of the drive motor 230, and the main control module 400 controlling the start and stop of the stirring mechanism 800, while realizing the control of the process of stirring the milk added with rennet, so as to improve the controllability of the emulsification process of stirring and heating the milk added with rennet, and improve the finished product quality of hard cheese while meeting the production quality control requirements of cheese.

[0093] In addition, based on the same inventive concept, the present invention also provides a method for producing hard cheese.

[0094] Continue to refer to Figures 1 to 6 and refer to Figure 7 , Figure 7 which is a schematic flowchart of the method for producing hard cheese according to the present invention.

[0095] In an embodiment of the present invention, as Figures 1 to 7 shown, a method for producing hard cheese, which is used for the above-mentioned hard cheese production device, the method for producing hard cheese includes the following steps:

[0096] Step S1: Install the carrier assembly 100 in the cheese emulsification and stirring tank, and use the image acquisition unit 300 to acquire an image of the standard color card 500, and send the standard color information to the main control module 400;

[0097] Step S2: Disinfect the milk and load it into the cheese emulsification and stirring tank;

[0098] Step S3: Add rennet to the milk to form a milk body;

[0099] Step S4: Stir the milk body by using the stirring mechanism 800, and sample the milk body by using the sampling color card 600;

[0100] Step S5: Use the image acquisition unit 300 to acquire an image of the sampling color card 600, obtain the color information of the milk body sample corresponding to the image of the sampling color card 600, and send the color information of the milk body sample to the main control module 400;

[0101] Step S6: Use the main control module 400 to compare the standard color information and the color information of the milk body sample, and output the comparison result; the comparison result includes the color difference value between the standard color and the color of the milk body sample;

[0102] Step S7: Determine whether the comparison result meets the preset conditions;

[0103] Step S8: If not, after an interval of the preset time, the main control module 400 controls the sampling mechanism 200 to start and rotate, so that another sampling color card 600 samples the milk body, and step S5 is executed again until the comparison result meets the preset conditions;

[0104] Step S9: Filter the milk body to form a cheese mass;

[0105] Step S10: Press the cheese mass and cool it to form hard cheese.

[0106] It should be noted that during the process of stirring the milk added with rennet in the cheese emulsification stirring tank to separate the milk fat and moisture in the milk and gradually cause the protein in the milk to form curds, continuous stirring will cause more and more milk fat to be separated from the milk, resulting in the liquid separated from the milk body becoming yellower and yellower. By analyzing the color of the liquid separated from the milk body, it can be determined whether the liquid in the milk body can be filtered to obtain dry cheese particles. Specifically:

[0107] According to the taste and type of cheese to be prepared, select the corresponding standard color card 500. The color types of the standard color card 500 are yellow;

[0108] Use the image acquisition unit 300 to photograph the standard color card 500, store the image color of the standard color card 500 in the storage module 320, and then send it to the main control module 400 as a sample;

[0109] During the stirring process, start the drive motor 230 to rotate the turntable 210 to drive the standard color card 500 out of the shooting range of the camera, and drive a sampling color card 600 to contact and sample the liquid in the milk body and then move it into the shooting range of the camera;

[0110] Use the image acquisition unit 300 to photograph the sampling color card 600 carrying the milk body, store the image color of the sampling color card 600 in the storage module 320, and then send it to the main control module 400 as a sample to be inspected;

[0111] Use the main control module 400 to compare the image color of the standard color card 500 and the image color of the sampling color card 600, and output the comparison result;

[0112] When the comparison result is ∆E = ∆L +, it means that the color of the liquid in the milk body is relatively white at this time, and the milk body needs to be continuously stirred;

[0113] When the comparison result is ∆E = ∆b +, it means that the color of the liquid in the milk body is relatively yellow at this time, and it is necessary to control the stirring mechanism 800 to stop working.

[0114] It should be understood that the specific structure of this hard cheese production device refers to the above-mentioned embodiments. Since this hard cheese production method adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated here one by one.

[0115] Furthermore, the color difference between the standard color and the color of the milk body sample is ∆E. Before step S9, it further includes:

[0116] When the comparison result meets the preset conditions, the main control module 400 controls the stirring mechanism 800 to stop;

[0117] The preset condition is 0 ≤ ∆E ≤ 0.5.

[0118] It should be understood that, in order to more easily control the stirring time of the stirring mechanism 800 and prevent the quality of the cheese from deteriorating due to too long or too short stirring time, it is only necessary to stop the stirring mechanism 800 when ∆E meets the preset condition.

[0119] As an alternative implementation of the above embodiment, when the comparison result is ∆E = ∆L+, a preset time interval is set. After the preset time interval, the drive motor 230 is started to rotate another sampling color card 600 into the cheese emulsification stirring tank and contact the milk liquid to re-sample, and step S5 is re-executed until the comparison result meets the preset condition.

[0120] It should be noted that the visible light frequency of the standard color card 500 is 510 THz to 525 THz.

[0121] It should be noted that the serial numbers of the above embodiments of the present invention are only for description and do not represent the advantages or disadvantages of the embodiments. The above embodiments are only optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or directly or indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
