Description

Technical Field

[0001] The invention relates to the technical field of nutritious meal product processing, and in particular to a production and processing method of nutritious meal products. Background Art

[0002] Nutritional meal products usually refer to foods that are specially formulated to provide rich nutrients, meet specific dietary needs or support a healthy lifestyle. Liquid Super Muscle Meal is a nutritional supplement designed for fitness enthusiasts, athletes and people with specific nutritional needs who need to gain muscle and weight. It is a common nutritional meal product. The purpose of this type of product design is to provide fast and convenient nutritional supplements, especially when additional nutritional support is needed before and after training. It has the advantages of diverse flavors, portability and fast absorption. The current representative liquid super muscle meal is It is mainly prepared from raw materials such as milk protein, whey protein, casein, coconut oil, linseed oil, maltodextrin, polydextrose, vitamins, minerals, etc. The main nutritional content includes 20g / 370g protein, 10.5g / 370g fat, 60g / 370g carbohydrates, 7g / 370g dietary fiber, 8 kinds of vitamins and 4 kinds of minerals, a total of 12 trace nutrients. It generally includes raw material preparation and mixing, high-pressure homogenization, filtration, vacuum degassing, ultra-high temperature instantaneous sterilization, aseptic cold filling, labeling and coding, and box packaging.

[0003] The existing high-pressure homogenization step and filtration step require the mixed liquid to be transported to different equipment for processing. When transported from one equipment to another, the mixed liquid will be retained or lost in the pipeline, resulting in an increase in overall material loss, and the transportation process of the mixed liquid between different equipment will also increase the time, causing the overall processing speed to slow down; and in the existing filtration method, the mixed liquid is always concentrated in a single position of the filter screen, and the undissolved particles filtered by the filter screen are not convenient to be discharged from the filter screen in time. Since the undissolved particles in the filtered liquid continue to accumulate on the filter screen, as time goes by, the surface of the filter screen will gradually be blocked by particles and the filtration area of ​​the filter screen will be reduced, resulting in a slowdown in the filtration flow rate, resulting in a decrease in the overall filtration effect. Summary of the invention

[0004] The present invention provides a production and processing method for nutritious meal products, which solves the problem that in the existing high-pressure homogenization and filtration steps, a mixed liquid needs to be transported to different equipment for processing, resulting in the mixed liquid being retained or lost in the pipeline, increasing material loss and prolonging the processing time, thereby reducing the overall processing speed. At the same time, in the existing filtration method, the mixed liquid is always concentrated in a single position of the filter screen, and undissolved particles are difficult to be discharged in time. As the particles accumulate, the surface of the filter screen is gradually blocked, the filtration area is reduced, the filtration flow rate is slowed down, and the overall filtration effect is reduced.

[0029] In the present invention, the number of collisions between the mixed liquid and the spoiler knife group during the processing process is increased by using a spoiler knife group that can swing back and forth in the homogenization processing part, thereby increasing the collision and shearing effect between particles, and refining larger particles into smaller sizes, thereby effectively refining the particles in the mixed liquid. At the same time, the spoiler knife group can also increase the collision area with the mixed liquid flow, so that the particles can be better dispersed in the mixed liquid, reducing particle aggregation, and optimizing the homogenization processing effect.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0044] See also Figure 1 and Figure 2 The present invention provides a technical solution: a production and processing method of a nutritious meal product. The specific production and processing method of the nutritious meal product has the following steps:

[0045] S1. Raw material preparation and mixing: fully and evenly mix the prepared nutrient raw materials according to the formula ratio to obtain a mixed solution.

[0046] S2, high-pressure homogenization: The mixed liquid prepared in S1 is pressurized and pumped into the homogenization and filtration integrated mechanism 3 by a high-pressure pump for high-pressure homogenization. When the mixed liquid enters the homogenization and filtration integrated mechanism 3, the large particles in the mixed liquid are subjected to strong shearing and impact forces, and are thus broken into smaller particles, thereby refining the particles in the mixed liquid.

[0047] S3, filtration: The mixed liquid after the high-pressure homogenization processing of S2 is filtered through the integrated homogenization and filtration mechanism 3 to remove the undissolved particles and impurities in the mixed liquid. The integrated homogenization and filtration mechanism 3 can also automatically discharge the filtered undissolved particles and impurities in time while filtering.

[0048] S4. Vacuum degassing: The mixed liquid after S3 filtration is subjected to vacuum degassing treatment under vacuum conditions to remove dissolved gas and entrained air.

[0049] S5, ultra-high temperature instantaneous sterilization: heat the mixed liquid after S4 vacuum degassing to above 135℃ and keep it for a few seconds for ultra-high temperature instantaneous sterilization, and then quickly cool it to room temperature to completely kill bacteria and microorganisms to obtain liquid super muscle nutrition meal solution.

[0050] S6. Aseptic cold filling: Fill the liquid super muscle nutrition meal obtained in S5 into a packaging container in a sterile environment to obtain a semi-finished nutrition meal.

[0051] S7, labeling and coding: labeling the semi-finished nutritious meal obtained in S6, and printing the production date and batch number to obtain the nutritious meal product.

[0052] S8. Packing: Pack the nutritional meal products into cartons, place a certain number of products in each carton and seal them tightly.

[0053] The production and processing method steps of the nutritious meal products in the above steps S1-S8 need to be completed by the support 1, the mounting plate 2 and the homogenizing and filtering integrated mechanism 3.

[0054] The upper end surface of the support 1 is fixedly connected with a mounting plate 2, and a homogenizing and filtering integrated mechanism 3 for homogenizing and filtering the mixed liquid is jointly arranged between the mounting plate 2 and the support 1. The homogenizing and filtering integrated mechanism 3 includes a homogenizing processing part 31 arranged on the mounting plate 2 for enhancing the shear force during the homogenization of the mixed liquid to make the particles in the mixed liquid more refined, and a self-scraping filtering part 32 arranged between the support 1 and the mounting plate 2 and located directly below the homogenizing processing part 31 for filtering the mixed liquid after the homogenization and automatically and timely discharging the filtered undissolved particles.

[0055] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the homogenizing processing part 31 includes a valve seat 311 fixedly connected to the upper front end surface of the mounting plate 2 through a fixing strip, a valve body 312 is fixedly connected to the front end surface of the valve seat 311, a plurality of S-shaped valve channels 313 are equidistantly provided between the valve seat 311 and the valve body 312, an inlet pipe 314 connected to the S-shaped valve channel 313 is fixedly connected to the upper end surface of the valve seat 311 and the valve body 312, a plurality of shearing pieces 315 are fixedly connected to the front and rear groove walls of the S-shaped valve channel 313 along an automatic path, and a plurality of shearing pieces 315 are equidistantly connected to the valve seat 311 along the path of the S-shaped valve channel 313. There are several rotating columns, the front end of which extends into the S-shaped valve channel 313 and is fixedly connected to a spoiler knife group 316. A drive swing assembly 317 for driving the rotating column to reciprocate is provided between the valve seat 311 and the fixed bar. The drive swing assembly 317 includes two electric sliders 3171 which are symmetrically slidably connected to the rear end surface of the valve seat 311, and a frame 3172 is fixedly connected between the two electric sliders 3171. A gear 2 3173 is fixedly connected to the outside of the rotating column, and a rack 3174 meshing with the gear 2 3173 is fixedly connected to each transverse section of the frame 3172 at an equidistant distance.

[0056] The mixed liquid is pressurized to a high pressure state (usually 100MPa-200MPa) by a high-pressure pump, and then the pressurized mixed liquid is pumped into the input pipe 314 in the homogenization processing part 31. The mixed liquid is then pumped into the S-shaped valve channel 313 under high pressure. During the high-speed passage of the mixed liquid in the S-shaped valve channel 313, it will collide with the shear plate 315, so that the large particles in the mixed liquid are subjected to strong shear force and impact force and are broken into smaller particles. The mixed liquid passing through the narrow gap of the S-shaped valve channel 313 will also produce strong eddy currents and cavitation effects, further refining the particles. At the same time, the electric slider 3171 is controlled to move back and forth laterally, and the electric slider 3171 then drives the rack 3174 to move back and forth laterally through the frame 3172, and the rack 3174 then drives the rotating column to rotate back and forth through the gear 2 3173, and the rotating column then drives the spoiler knife group 316 to swing back and forth, thereby increasing the collision area between the mixed liquid and the spoiler knife group 316 when the mixed liquid flows in the S-shaped valve channel 313, thereby further crushing and refining the particles in the mixed liquid until the mixed liquid is ejected from the lower port of the S-shaped valve channel 313, and the homogenization and refining processing of the mixed liquid can be completed.

[0057] See also Figure 6 and Figure 7 In this embodiment, the self-scraping filter part 32 includes two support plates 321 that are symmetrically fixedly connected to the upper end surface of the support 1, and the support plates 321 are symmetrically arranged in two rows front and back, and a buffer support component 322 is arranged between the two support plates 321, and an arc filter 323 is arranged on the buffer support component 322. The buffer support component 322 is used to buffer and weaken the impact of the mixed liquid sprayed from the homogenizing processing part 31 on the arc filter 323 during filtering. A self-scraping component 324 for timely scraping away the undissolved particles filtered from the arc filter 323 is commonly arranged between the front and rear support plates 321. The two self-scraping components 324 are symmetrically distributed on the left and right, and a converging component 325 for gathering the mixed liquid sprayed from the homogenizing mixing part is arranged at the front of the mounting plate 2 and between the self-scraping component 324 and the homogenizing processing part 31.

[0059] See also Figure 7 , Fig. 9 and Fig.10 The reciprocating driving member 3b includes a rotating shaft 3b1 rotatably connected between the front and rear support plates 321, a paddle wheel 3b2 is fixedly connected to the outside of the rotating shaft 3b1, an incomplete gear 3b3 is fixedly connected to the rear of the rotating shaft 3b1, a rotating shaft 3b4 is rotatably connected to the front end surface of the support plate 321 at the rear, a gear 3b5 that cooperates with the incomplete gear 3b3 is fixedly connected to the outside of the rotating shaft 3b4, a telescopic lever 3b6 is fixedly connected to the outside of the rotating shaft 3b4, and the lower end of the telescopic lever 3b6 is hinged to the sliding sleeve 3242 at the rear.

[0060] See also Figure 2 and Figure 6 The focusing assembly 325 includes two arc baffles 3251 which are symmetrically fixed to the front end surface of the mounting plate 2 through fixing rods and are movably mounted on the outside of the paddle wheel 3b2. The upper part of the arc baffle 3251 is fixedly connected to an inclined guide plate 3252 located directly below the homogenizing treatment part 31.

[0061] See also Figure 8 The control member 3a includes an arc guide frame 3a1 fixedly connected to the upper part of the arc rail 3241 through a connecting block, a slider 3a2 is slidably connected with the arc guide frame 3a1 by interference fit, and levers 3a3 are hinged on opposite sides of the front and rear sliders 3a2. The upper end of the lever 3a3 is hinged to the transverse section of the L-shaped seat 3243, and a limiting plate 3a4 for limiting the position of the lever 3a3 is fixedly connected to the side of the slider 3a2 close to the L-shaped seat 3243.

[0062] See also Fig. 9 and Fig.10The reset member 3c includes an arcuate sliding groove 3c1, a sliding block 3c2 and a reset spring 3c3. The arcuate rail 3241 is provided with an arcuate sliding groove 3c1 on the side away from the L-shaped seat 3243. The inner wall of the sliding sleeve 3242 is fixedly connected with a sliding block 3c2 that is slidably connected in the arcuate sliding groove 3c1. A reset spring 3c3 is fixedly connected between the arcuate sliding groove 3c1 and the sliding block 3c2.

[0063] A portion of the mixed liquid sprayed from the lower part of the valve body 312 and the valve seat 311 will impact the inclined guide plate 3252, then flow toward the middle along the inclined surface of the inclined guide plate 3252, and then flow downward to impact the blades of the paddle wheel 3b2, while the other portion of the mixed liquid (i.e., the area located between the two rotating shafts 3b1) will directly impact the paddle wheel 3b2, so that the two paddle wheels 3b2 rotate in opposite directions respectively. The mixed liquid flowing out of the homogenizing treatment part 31 interacts with the paddle wheel 3b2 so that the paddle wheel 3b2 can impact the mixed liquid while being impacted and rotated. When the paddle wheel 3b2 blades rotate, the mixed liquid is dispersed under the action of centrifugal force, so that the mixed liquid is discharged from multiple directions and enters the arc filter screen 323. After impacting the paddle wheel 3b2, the mixed liquid flows downward and enters the arc filter screen 323, and is filtered by the arc filter screen 323.

[0064] After the paddle wheel 3b2 is impacted and rotated by the mixed liquid, it then drives the incomplete gear 3b3 to rotate through the rotating shaft 3b1. When the incomplete gear 3b3 engages with the gear 1 3b5, it drives it to rotate. The gear 1 3b5 then drives the telescopic lever 3b6 to rotate through the rotating shaft 3b4. The telescopic lever 3b6 then drives the sliding sleeve 3242 to move along the arc track 3241 from the initial position toward the middle away from the arc filter 323 (the initial position of the sliding sleeve 3242 is located at the shortest distance between the left and right sliding sleeves 3242).

[0065] The sliding sleeve 3242 then drives the L-shaped seat 3243 to move, and the L-shaped seat 3243 then drives the scraper 3244 to move. During the movement of the sliding sleeve 3242 away from the middle of the arc-shaped filter screen 323, since the slider 3a2 and the arc-shaped guide frame 3a1 are connected in an interference fit manner, there is friction resistance between the slider 3a2 and the arc-shaped guide frame 3a1. Therefore, the movement of the sliding sleeve 3242 at this time will pull the lever 3a3 through the L-shaped seat 3243 to rotate around the hinge between the lever 3a3 and the slider 3a2, and the rotating lever 3a3 drives the L-shaped seat 3243 to gradually move downward, and the L-shaped seat 3243 then moves downward. Then the scraper 3244 is driven to move downward until it contacts the upper surface of the arc filter 323, and then the sleeve 3242 drives the L-shaped seat 3243, the lever 3a3 and the slider 3a2 to move synchronously, so that the slider 3a2 offsets the friction between it and the arc guide frame 3a1 and then slides in the arc guide frame 3a1. The scraper 3244 contacts the upper surface of the arc filter 323 and moves upward to scrape the undissolved particles that have been filtered and intercepted upward until the undissolved particles are scraped to the inclined guide plate 4, and then the undissolved particles are discharged to the outside under the action of the inclined surface of the inclined guide plate 4.

[0066] At this time, the incomplete gear 3b3 rotates to separate from the gear 1 3b5, and then the return spring 3c3 in the compressed state begins to return and pushes the sliding sleeve 3242 to move along the arc track 3241 toward the middle of the arc filter 323. In this process, the sliding sleeve 3242 will move synchronously by driving the L-shaped seat 3243, so that the L-shaped seat 3243 pushes the lever 3a3 to rotate around the hinge point between the lever 3a3 and the slider 3a2, until the lever 3a3 rotates to abut against the limit plate 3a4 and stops rotating. 3 drives the L-shaped seat 3243 to gradually move upward, and the L-shaped seat 3243 then drives the scraper 3244 to move upward, so that the scraper 3244 is separated from the arc-shaped filter screen 323; when the lever 3a3 rotates until it contacts the limit plate 3a4, the sliding sleeve 3242 drives the slider 3a2 to move synchronously through the L-shaped seat 3243 and the lever 3a3, and then the slider 3a2 starts to slide in the arc-shaped guide frame 3a1, thereby preventing the scraper 3244 from scraping the undissolved particles on the arc-shaped filter screen 323 to the middle of the arc-shaped filter screen 323 during the reset movement.

[0067] After the sleeve 3242 quickly moves to the initial position, the incomplete gear 3b3 rotates to mesh with the gear 1 3b5 again, and then the above steps are repeated again. The incomplete gear 3b3 drives the gear 1 3b5 to rotate, and the gear 1 3b5 then drives the scraper 3244 through the control member 3a. The scraper 3244 again contacts the arc filter 323 and moves laterally from the middle of the arc filter 323 to scrape away the undissolved particles intercepted on the arc filter 323 again, so that the undissolved particles filtered by the arc filter 323 can be discharged in time, ensuring that the arc filter 323 is always in the best filtering state.

[0068] See also Figure 6 , Figure 7 and Fig. 9 In this embodiment, the buffer support component 322 includes an arc-shaped support bar 3221, a horizontal auxiliary rod 3222 and a top spring 3223. The two horizontal support plates 321 are fixedly connected to the arc-shaped support bar 3221 on one side close to the homogenizing processing part 31. The arc-shaped filter screen 323 is fixedly connected to the upper part of the two arc-shaped support bars 3221. The opposite sides of the two arc-shaped support bars 3221 are fixedly connected with a plurality of horizontal auxiliary rods 3222 at equal intervals along the arc of the arc-shaped support bars 3221. The horizontal auxiliary rod 3222 is fixedly connected with a plurality of top springs 3223 that touch the lower surface of the arc-shaped filter screen 323 at equal intervals. The longitudinal section of the horizontal auxiliary rod 3222 is an equilateral triangle shape. The inclined surface of the horizontal auxiliary rod 3222 is used to enable the mixed liquid flowing out from under the arc-shaped filter screen 323 to be quickly discharged along the inclined surface when it contacts the horizontal auxiliary rod 3222, thereby reducing the amount of mixed liquid attached to the horizontal auxiliary rod 3222.

[0069] When the mixed liquid flows downward and impacts the arc-shaped filter screen 323, a plurality of top springs 3223 arranged along the arc direction and the front-to-back direction provide elastic support to the lower surface of the arc-shaped filter screen 323 from multiple support points. When the arc-shaped filter screen 323 is impacted by the mixed liquid sprayed from the homogenizing processing section 31, the elastic support can effectively absorb a part of the impact and make the force distribution of the arc-shaped filter screen 323 uniform, thereby ensuring that the working state of the arc-shaped filter screen 323 remains stable and avoiding displacement or deformation of the filter screen due to impact. At the same time, the arc-shaped filter screen 323 will not directly bear excessive impact pressure, thereby reducing the risk of damage to the arc-shaped filter screen 323.
