Description

Technical Field

[0001] The invention relates to the technical field of food processing, and more specifically to a blueberry enzyme beverage, a preparation method and a preparation device thereof. Background Art

[0002] In the production process of blueberry enzyme beverages, the selection and processing of raw materials are crucial links. Blueberry enzyme beverages usually contain a variety of berries, such as blueberries, red beans, mulberries and cherries, which not only provide a rich taste and flavor for the beverage, but are also rich in a variety of nutrients that are beneficial to the human body, such as vitamins, minerals and antioxidants. However, in the process of converting these berries into beverages, especially in the crushing stage before enzymatic hydrolysis, the existing crushing devices face some technical challenges.

[0003] Most existing crushing devices are designed to process berries of a single type or similar size. However, berries such as blueberries, red beans, mulberries and cherries have significant differences in size and shape. For example, blueberries are usually small and round, while red beans are large and irregular in shape, mulberries are small but have a hard skin, and cherries are large and contain pits. These differences make it difficult for existing crushing devices to achieve ideal crushing effects when processing these berries at the same time.

[0004] And because the peel and pulp of berries are relatively soft, they are easily thrown out when whipping and adhere to the inside of the crushing device, which not only increases the difficulty of cleaning the equipment, but also may lead to a decrease in production efficiency and unstable product quality. The internal structure of the device is complex, and the adhered pulp and peel are not easy to clean. If the cleaning frequency is not high enough, the pulp and peel adhered to the inner wall will rot and breed bacteria, which will affect the hygiene and product quality of subsequent production. Frequent cleaning work is not only time-consuming and labor-intensive, but also reduces production efficiency and increases production costs.

[0005] In view of the above problems, there is an urgent need for a crushing device that can efficiently crush berries while reducing splashing and adhesion and reducing the difficulty of cleaning, so as to solve the problem of low production efficiency leading to increased production costs and prevent the production cycle and output of blueberry enzyme beverages from being affected. In view of this, we propose a blueberry enzyme beverage, a production method and a production device. Summary of the invention

[0011] Step 4: Slurry A and slurry B are mixed in a volume ratio of 2:1 to obtain a mixed slurry, skim milk (mass fraction of 3%), brown sugar (mass fraction of 0.8%) and xanthan gum (mass fraction of 0.07%) are added to the mixed slurry to obtain a mixture, and the obtained mixture is sterilized at 75-80° C. for 10-15 min, and then cooled to room temperature;

[0012] Step 5: After activating plant lactic acid bacteria, Lactobacillus rhamnosus, Lactobacillus casei, yeast and acetic acid bacteria, they are inoculated into the mixture prepared in step 4 according to inoculation ratios (mass fractions are 0.1%, 0.5%, 0.5%, 0.15% and 0.5%, respectively), and after fermentation, filtration and sterilization, a blueberry enzyme beverage is obtained, which is finally canned into a product.

[0024] Preferably, the method for using the above-mentioned screening and crushing equipment comprises the following steps:

[0025] S1, berry screening operation;

[0026] Berries such as blueberries, red beans, mulberries and cherries are first sieved by size through a vibrating sieving mechanism and then evenly put into the hopper in batches;

[0027] S2, crushing particle size adjustment operation;

[0028] Choose the appropriate gap treatment according to the size of the berries to be crushed;

[0029] S2.1. If the berries to be processed are small in size, the servo motor is driven to rotate forward to drive the second belt to pull the adjustment shaft to rotate in the output shaft. Since the output shaft is fixedly connected to the central gear, the output shaft drives the central gear to rotate. The central gear rotates and meshes synchronously to drive the five planetary gears to rotate. The rotation of the planetary gears drives the whipping assembly to rotate outward, compressing the gap between the inner wall of the crushing chamber and the whipping arc plate, so as to adjust the particle size of the berry crushing;

[0030] S2.2, if the size of the berries to be processed is large, the servo motor is driven to reverse and drive the second belt to pull the adjustment shaft to rotate in the output shaft. Since the output shaft and the central gear are fixedly connected, the output shaft drives the central gear to rotate, and the central gear rotates synchronously and drives the five planetary gears to rotate. The rotation of the planetary gears drives the whipping assembly to rotate inward, releasing the gap between the inner wall of the crushing chamber and the whipping arc plate, so as to adjust the particle size of the berry crushing;

[0031] S3, berry crushing and water injection operation;

[0032] The servo motor is driven to drive the second belt to pull the adjusting shaft to rotate in the output shaft, and the output shaft drives the central gear to rotate. The central gear rotates and meshes synchronously to drive the five planetary gears to rotate. The planetary gears rotate and mesh with the synchronous gears. The synchronous gears rotate and mesh with the rack plate, and the rack plate slides on the insertion hole of the sleeve to extend and retract. Since the injection plate is fixedly connected to the rack plate, the rack plate drives the injection plate to extend and retract synchronously. The external water source enters multiple telescopic hoses through the multi-tube joints and is injected into the injection plate and then sprayed out. Then the reduction motor is driven to drive the first belt to pull the output shaft to rotate on the shaft seat, thereby realizing synchronous water injection during the crushing and beating process.

[0033] S4, cleaning operation of inner wall residue;

[0034] When the berries are not crushed, the berry crushing mechanism is idle, the external water source is pressurized, and the water source is rotated and sprayed out through the spray holes of the spray plate to efficiently clean the crushing chamber.

[0035] The present invention also provides a blueberry enzyme beverage prepared by the preparation method of the above-mentioned blueberry enzyme beverage, wherein the blueberry enzyme beverage comprises the following raw materials in parts by weight: 50 parts of blueberries, 5 parts of red bean fruits, 15 parts of mulberries, 15 parts of cherries, 5 parts of schisandra fruits, 5 parts of acanthopanax fruits, 3 parts of skim milk, 0.8 parts of brown sugar, 0.07 parts of xanthan gum, 0.1 parts of plant lactic acid bacteria, 0.5 parts of rhamnosus lactobacillus, 0.5 parts of casei lactobacillus, 0.15 parts of yeast, 0.5 parts of acetic acid bacteria, and the rest is water.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The present invention provides a driving mechanism on the frame, a berry crushing mechanism on the front of the frame, the driving mechanism is connected to the berry crushing mechanism, a feeding hopper is provided at the top of the berry crushing mechanism, a spiral feeder is provided at the bottom of the berry crushing mechanism, a mounting frame is provided at a position directly above the frame, a vibration screening mechanism is provided on the mounting frame, and the output end of the vibration screening mechanism is connected to the input end of the feeding hopper; the berries are first screened by size through the vibration screening mechanism, the crushing particle size of the whipping component is adjusted by the adjustment component, and then the berries of the same size are put into the crushing box, and the whipping component is driven by the driving mechanism to rotate in the crushing box for efficient crushing, and a synchronous cleaning component is also provided on the berry crushing mechanism. In the process of crushing the berries, water is injected synchronously when the berries are evenly whipped through the synchronous cleaning component, which makes the uniform effect better, and there will be no strong granularity and sediment that affect the taste. After crushing, water can be injected separately for rotation and spraying. The present invention has high manufacturing, production and maintenance efficiency.

[0038] 2. In the present invention, the second belt is driven by a servo motor to pull the adjustment shaft to rotate in the output shaft. Since the output shaft is fixedly connected to the central gear, the output shaft drives the central gear to rotate, and the central gear rotates synchronously to drive the five planetary gears to rotate, and the planetary gears rotate to drive the whipping assembly to rotate, so as to adjust the particle size of the berry crushing. Since different berries have different sizes, hardness and shapes, the design of the adjustable gap enables the berry crushing mechanism to adapt to the crushing needs of various berries. By quickly adjusting the gap, not only can it ensure that all kinds of berries can get a uniform crushing effect, but also can quickly solve the shutdown problem caused by material blockage or poor crushing effect, reduce downtime, and improve production efficiency.

[0039] 3. In the present invention, a crushing cone is arranged on the outer wall of the whipping arc plate. The design of the crushing cone enables a more delicate crushing effect to be produced when crushing the berries, and the berries are crushed into smaller particles, thereby increasing the fineness and smoothness of the blueberry enzyme beverage and improving the overall taste experience. In addition, the fine crushing reduces the difficulty and time consumption of the subsequent processing steps, thereby improving the production efficiency of the entire blueberry enzyme beverage production line. At the same time, due to the better crushing effect, the required crushing time and energy consumption are also reduced accordingly.

[0040] 4. The present invention also rotates and sets a sleeve on the inner wall of the inspection door panel. When the servo motor drives the second belt to pull the adjustment shaft to rotate in the output shaft, the output shaft drives the central gear to rotate, and the central gear rotates synchronously and meshes to drive the five planetary gears to rotate. The planetary gears rotate and mesh with the synchronous gears, and the synchronous gears rotate and mesh with the rack plate to slide on the inserted card hole of the sleeve to retract. Since the injection plate is fixedly connected to the rack plate, the rack plate drives the injection plate to retract synchronously. The external water source enters multiple telescopic hoses through a multi-tube joint and is injected into the injection plate and then ejected. Water is injected during the crushing and whipping process, which helps the berries to be more fully mixed and crushed during the crushing process to form finer particles. This increases the smoothness and fineness of the blueberry beverage enzyme, making the taste softer and more comfortable. The design of adding water synchronously also simplifies the production process and reduces the difficulty and time-consuming of subsequent processing steps. This helps to further improve the production efficiency of blueberry beverage enzymes and reduce production costs.

[0041] 5. When the berries are not crushed, the present invention idles the berry crushing mechanism, pressurizes the external water source, and the water source is rotated and sprayed out through the spray holes of the spray plate, simulating the throwing path of the pomace during the crushing process, which can more accurately locate and clean those areas where pulp and peel are easily accumulated, and the rotary cleaning can cover a wider area, ensuring that every corner inside the crushing device can be thoroughly cleaned. Regular and effective cleaning can prevent the pulp and peel from rotting and breeding bacteria inside the device, thereby protecting the equipment from corrosion and damage.

When the servo motor 3022 drives the second belt 3023 to pull the adjusting shaft 3024 to rotate in the output shaft 204, the output shaft 204 drives the central gear 3027 to rotate, and the central gear 3027 rotates and synchronously engages to drive the five planetary gears 3026 to rotate, and the planetary gears 3026 rotate and engage the synchronous gear 3043 to rotate, and the synchronous gear 3043 rotates and engages the rack plate 3044 to slide on the insertion hole 3042 of the sleeve 3041 to retract and retract. Since the injection plate 3045 is fixedly connected to the rack plate 3044, the rack plate 3044 drives the injection plate 3045 to retract and retract synchronously, and the external water source enters the multiple telescopic hoses 3052 through the multi-tube joint 3051 and is injected into the injection plate 3045 and then sprayed out. Injecting water during the crushing and whipping process helps to more fully mix and crush the berries during the crushing process to form finer particles. This increases the smoothness and fineness of the blueberry beverage enzyme, making the taste softer and more comfortable. The design of adding water simultaneously also simplifies the production process and reduces the difficulty and time-consuming of subsequent processing steps such as stirring and mixing. This helps to further improve the production efficiency of blueberry beverage enzymes and reduce production costs.

[0079] When the berries are not crushed, the present invention idles the berry crushing mechanism, pressurizes the external water source, and the water source is rotated and sprayed out through the spray holes 3046 of the spray plate 3045, simulating the throwing path of the pomace during the crushing process, and can more accurately locate and clean those areas where pulp and peel are easily accumulated, and the rotary cleaning can cover a wider area, ensuring that every corner inside the crushing device can be thoroughly cleaned. Regular and effective cleaning can prevent the pulp and peel from rotting and breeding bacteria inside the device, thereby protecting the equipment from corrosion and damage.

[0080] Embodiment 2: This embodiment provides a method for preparing a blueberry enzyme beverage, comprising the following steps:

[0081] Step 1: Put the washed and dried blueberries, red beans, mulberries and cherries into the screening and crushing equipment. First, they are screened by size through the vibrating screening mechanism 7 and then evenly put into the hopper 4 in batches; then, the appropriate gap processing is selected according to the size of the crushed berries:

[0082] If the size of the processed berries is small, the servo motor 3022 is driven to rotate forward to drive the second belt 3023 to pull the adjustment shaft 3024 to rotate in the output shaft 204. Since the output shaft 204 and the central gear 3027 are fixedly connected, the output shaft 204 drives the central gear 3027 to rotate. The central gear 3027 rotates and engages synchronously to drive the five planetary gears 3026 to rotate. The planetary gears 3026 rotate and drive the whipping assembly 303 to rotate outward, compressing the gap between the inner wall of the crushing chamber 3013 and the whipping arc plate 3032, so as to adjust the particle size of the crushed berries.

[0083] If the size of the berries to be processed is large, the servo motor 3022 is driven to reverse and drive the second belt 3023 to pull the adjustment shaft 3024 to rotate in the output shaft 204. Since the output shaft 204 and the central gear 3027 are fixedly connected, the output shaft 204 drives the central gear 3027 to rotate. The central gear 3027 rotates and engages synchronously to drive the five planetary gears 3026 to rotate. The planetary gears 3026 rotate and drive the whipping assembly 303 to rotate inward, releasing the gap between the inner wall of the crushing chamber 3013 and the whipping arc plate 3032, so as to adjust the particle size of the berry crushing.

[0084] Pure water is injected synchronously according to the material-liquid ratio of 1:1.5. Specifically, the servo motor 3022 can be driven to drive the second belt 3023 to pull the adjustment shaft 3024 to rotate in the output shaft 204, and the output shaft 204 drives the central gear 3027 to rotate. The central gear 3027 rotates synchronously to drive the five planetary gears 3026 to rotate. The planetary gears 3026 rotate to mesh with the synchronous gear 3043, and the synchronous gear 3043 rotates to mesh with the rack plate 3044 in the sleeve 3041. The spray plate 3045 is fixedly connected to the rack plate 3044, and the rack plate 3044 drives the spray plate 3045 to synchronously extend and retract. The external water source enters the multiple telescopic hoses 3052 through the multi-tube joint 3051 and is injected into the spray plate 3045 and then sprayed out. Then, the reduction motor 201 is driven to drive the first belt 202 to pull the output shaft 204 to rotate on the shaft seat 203, thereby realizing synchronous water injection during the crushing and whipping process.

[0085] When the berries are not crushed, the berry crushing mechanism 3 is idle, the external water source is pressurized, and the water source is rotated and sprayed out through the spray holes 3046 of the spray plate 3045 to efficiently clean the crushing chamber 3013;

[0086] Step 2: Add compound enzyme A to the mixed slurry obtained in step 1, and perform ultrasonic treatment at 50° C. for 30 minutes to form slurry A after enzymatic hydrolysis; wherein the compound enzyme A is a mixture of pectinase, cellulase and hemicellulase;

[0087] Step 3: Take equal weights of Acanthopanax senticosus fruit and Schisandra chinensis fruit, add purified water at a material-liquid ratio of 1:10, and boil for 30 minutes for ripening; add compound enzyme B to the ripened material, perform ultrasonic treatment for 30 minutes, and enzymatically hydrolyze the material to form slurry B; wherein the compound enzyme B is a mixture of pectinase and cellulase;

[0088] Step 4: Mix slurry A and slurry B to obtain a mixed slurry, add skim milk, brown sugar and xanthan gum to the mixed slurry to obtain a mixture, sterilize the obtained mixture at 75-80° C. for 10-15 minutes, and then cool to room temperature;

[0089] Step 5: After activating plant lactic acid bacteria, Lactobacillus rhamnosus, Lactobacillus casei, yeast and acetic acid bacteria, inoculate them into the mixture prepared in step 4 according to the inoculation ratio, obtain a blueberry enzyme beverage after fermentation, filtration and sterilization, and finally can it into a product.

[0090] The blueberry enzyme beverage comprises the following raw materials in parts by weight: 50 parts of blueberries, 5 parts of red bean fruits, 15 parts of mulberries, 15 parts of cherries, 5 parts of schisandra fruits, 5 parts of acanthopanax fruits, 3 parts of skim milk, 0.8 parts of brown sugar, 0.07 parts of xanthan gum, 0.1 parts of plant lactic acid bacteria, 0.5 parts of rhamnosus lactobacillus, 0.5 parts of casei lactobacillus, 0.15 parts of yeast, 0.5 parts of acetic acid bacteria, and the rest is water.

[0091] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
