Description

Technical Field

[0001] This invention relates to the field of pickling machine technology, and in particular to a pickling machine with low-temperature humidity control and synergistic regulation. Background Technology

[0002] Pickling was a very effective method for preserving vegetables in the early days. Nowadays, pickling vegetables has evolved from a simple preservation method into a processing technology for unique flavored vegetable products. Pickled vegetables, a traditional food, are the crystallization of the wisdom of the Chinese people over the generations and are part of our cultural wealth.

[0003] In existing technologies, traditional hand-curing techniques are mainly suitable for small-scale family consumption. This production method cannot guarantee the safety of cured foods, and the fermentation process is uncontrollable. Temperature fluctuations can lead to unstable activity of microorganisms such as lactic acid bacteria and putrefactive bacteria, easily causing over-fermentation or spoilage. High humidity environments promote the proliferation of harmful bacteria (such as E. coli), while low humidity inhibits beneficial bacteria (such as lactic acid bacteria), resulting in poor fermentation. In addition, differences in temperature and humidity can cause uneven fermentation in different parts of the fish or other materials, resulting in problems such as hardening or loose texture. Therefore, a curing machine that can coordinately regulate low temperature and humidity is needed to achieve precise control of the fermentation process, ensuring the stability of the quality and food safety of cured products. Summary of the Invention

[0014] The beneficial effects of this invention are: In this invention, the needle plate of the pretreatment module is used to puncture the material, allowing the pickling liquid to fully penetrate the material and ensuring uniform flavor throughout the fermentation chamber.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1 like Figures 1-6 As shown in the figure, this embodiment elaborates on the overall basic structure of a low-temperature and humidity-controlled pickling machine. The pickling machine mainly consists of three parts: a pretreatment module 1, a packaging module 2, and a low-temperature fermentation chamber 3. These modules work together to achieve precise pickling of the materials.

[0020] The pretreatment module 1 is located at the front end of the device and is used for pre-treatment of the materials to be marinated. It includes a conveyor housing 101, on the bottom of which a support 102 is fixedly installed. The support 102 provides stable support for the entire pretreatment module, preventing shaking during transport. A conveyor belt 103 is arranged on the conveyor housing 101 to transport the materials to be marinated (such as fish), enabling continuous material processing and improving processing efficiency. A pretreatment component is also arranged on the conveyor housing 101 to puncture the materials, facilitating thorough penetration of the subsequent marinating solution.

[0021] The encapsulation module 2 is used to seal the pretreated materials to provide an environment for anaerobic fermentation. It includes a fermentation chamber 201 and a sealing lid 202. The fermentation chamber 201 and the sealing lid 202 are compatible. After the materials and auxiliary materials are mixed, they are placed into the fermentation chamber 201, and the sealing lid 202 is closed to complete the encapsulation. The low-temperature fermentation chamber 3 is used to provide a controllable low-temperature and humidity-controlled fermentation environment. A refrigeration unit 301 is arranged outside the chamber. The refrigeration unit 301 is used to regulate the temperature inside the low-temperature fermentation chamber 3. A control and regulation terminal 304 is also arranged inside the low-temperature fermentation chamber 3. The control and regulation terminal 304 can set and monitor fermentation parameters to achieve precise control of temperature and humidity.

[0022] The core structure of the pretreatment component includes a fixed frame 4, which is fixedly installed on the conveying housing 101 of the pretreatment module 1. A fixed arm 401 is fixedly installed on the bottom side of the fixed frame 4, and a movable arm 402 is slidably installed on the side of the fixed arm 401. The movable arm 402 can slide up and down along the fixed arm 401. A needle plate 403 is fixedly installed at the bottom end of the movable arm 402. The needle plate 403 is provided with multiple piercing needles for piercing the material so that the pickling liquid can fully penetrate into the material and ensure uniform fermentation in all parts.

[0023] A vertical support 303 is arranged inside the low-temperature fermentation chamber 3. A two-layer placement rack 302 is fixedly installed on the vertical support 303. The two-layer placement rack 302 can be used to place the sealed fermentation box 201 in layers, making reasonable use of the internal space of the low-temperature fermentation chamber 3 and improving the batch pickling capacity. A ventilation box 6 is arranged on one side of the sealing module 2. The ventilation box 6 is used to provide an anaerobic environment for the fermentation box 201. The bottom side of the sealing cover 202 is provided with casters 609. The casters 609 facilitate the movement of the fermentation box 201, making it easy to put or take the fermentation box into or out of the low-temperature fermentation chamber 3.

[0024] The basic structure of this low-temperature and humidity-controlled pickling machine, through the rational layout and connection of its various modules, provides a stable platform for the precise pickling of materials. The pretreatment module 1 realizes the conveying and piercing of materials, the packaging module 2 realizes the sealing and anaerobic packaging of materials, and the low-temperature fermentation chamber 3 realizes the precise temperature and humidity control of the fermentation environment. The three work together to solve many of the drawbacks of traditional manual pickling.

[0025] Example 2 like Figure 4 As shown in the first embodiment, this embodiment provides a detailed description of the specific structure and working principle of the pretreatment component, focusing on the driving method and impurity removal function of the needle plate to ensure a smooth and hygienic puncture process.

[0026] To enable the reciprocating lifting and piercing of the needle plate 403, a motor 5 is fixedly installed on the fixed frame 4. The motor 5 provides power for the movement of the needle plate. A rotating disk 501 is fixedly installed at the output end of the motor 5. A transmission shaft 502 is rotatably installed between the rotating disk 501 and the needle plate 403. Both ends of the transmission shaft 502 are rotatably installed with rotating shafts 503, which are respectively fixedly installed on the rotating disk 501 and the needle plate 403. When the motor 5 starts, the output end of the motor 5 drives the rotating disk 501 to rotate. The rotating disk 501 drives the transmission shaft 502 to move through the rotating shaft 503. The transmission shaft 502 then drives the movable arm 402 to slide up and down along the fixed arm 401 through the rotating shaft 503 at the other end, thereby driving the needle plate 403 to reciprocate and lift, realizing continuous piercing of materials on the conveyor belt.

[0027] To prevent material residue from adhering to the puncture needle of the needle plate 403 during the puncture process and causing cross-contamination, an installation ring 404 is fixedly installed on the side of the needle plate 403. A sliding rod 405 is slidably installed on the bottom side of the installation ring 404. The sliding rod 405 can slide up and down along the installation ring 404. A cleaning plate 406 is fixedly installed at the bottom end of the sliding rod 405. The cleaning plate 406 cooperates with the needle plate 403. The cleaning plate 406 has a through hole corresponding to the puncture needle. The puncture needle can pass through the through hole to puncture the material.

[0028] A limiting plate 407 is fixedly installed on the bottom side of the impurity removal plate 406. The limiting plate 407 is used to limit the descent position of the impurity removal plate 406 to avoid excessive contact between the impurity removal plate and the conveyor belt 103, which would cause wear. A return spring 408 is movably sleeved on the slide rod 405. The two ends of the return spring 408 are fixedly installed on the impurity removal plate 406 and the mounting ring 404, respectively. The return spring 408 is always in a stretched state to provide the return force for the impurity removal plate 406.

[0029] The working process is as follows: When the needle plate 403 descends, the limiting plate 407 first contacts the conveyor belt 103 and is blocked. At this time, the needle plate 403 continues to descend, and the piercing needle passes through the through hole of the impurity removal plate 406 to pierce the material. At the same time, the slide rod 405 slides upward along the mounting ring 404, compressing the return spring 408. When the needle plate 403 rises, the return spring 408 returns to its original position, pushing the impurity removal plate 406 to move downward. The impurity removal plate 406 slides relative to the piercing needle, scraping off the material residue attached to the piercing needle, realizing automatic impurity removal, avoiding cross-contamination, and ensuring processing hygiene.

[0030] Example 3 like Figure 5 As shown, based on the above embodiments, this embodiment provides a detailed description of the sealing performance, air pressure regulation, and anaerobic environment construction method of the encapsulation module 2 to ensure the stability of the fermentation process.

[0031] To ensure the sealing performance of the fermentation chamber 201 and the sealing cover 202 and prevent air from entering and affecting the fermentation effect, sealing rings 203 are fixedly installed at the connection between the fermentation chamber 201 and the sealing cover 202. The two sealing rings 203 are compatible. When the sealing cover 202 is closed, the two sealing rings 203 fit tightly together to form a double seal, effectively isolating the outside air and ensuring anaerobic fermentation.

[0032] A pressure cage 204 is fixedly installed on the bottom side of the sealing cover 202. The pressure cage 204 has a mesh structure. When the sealing cover 202 is closed, the pressure cage 204 can press the material in the fermentation box 201 below the surface of the pickling liquid, ensuring that the material is fully in contact with the pickling liquid and preventing some material from floating on the surface, which would lead to uneven fermentation. A pressure sensor 206 is fixedly installed on the side wall of the fermentation box 201. The pressure sensor 206 is used to monitor the pressure inside the fermentation box 201 in real time. An exhaust valve 205 is fixedly installed on the sealing cover 202. The exhaust valve 205 is connected to the inside of the fermentation box 201. When gas is generated during fermentation and the pressure inside the box becomes too high, the pressure sensor 206 detects the abnormal pressure and can slowly release the gas through the exhaust valve 205 to ensure stable pressure inside the fermentation box and prevent damage to the sealing structure due to excessive pressure.

[0033] To create the anaerobic environment required for fermentation, a ventilation box 6 is arranged on one side of the encapsulation module 2. A vacuum pump 605 and a carbon dioxide delivery pump 607 are installed inside the ventilation box 6. The vacuum pump 605 is used to extract air from the fermentation chamber 201, and the carbon dioxide delivery pump 607 is used to inject carbon dioxide into the fermentation chamber 201. An extraction pipe 606 and a carbon dioxide delivery pipe 608 are respectively installed on the vacuum pump 605 and the carbon dioxide delivery pipe 607. The same three-way valve 604 is fixedly installed at the end of both the extraction pipe 606 and the carbon dioxide delivery pipe 608. A connecting pipe 601 is fixedly installed at the top of the sealing cap 202. A sealing valve 602 is arranged on the connecting pipe 601 to control the opening and closing of the connecting pipe 601. A gas supply pipe 603 is installed between the connecting pipe 601 and the three-way valve 604.

[0034] The process of constructing an anaerobic environment is as follows: After covering the sealing cap 202 and ensuring a seal, open the sealing valve 602 and the three-way valve 604, start the vacuum pump 605, and extract air from the fermentation chamber 201 through the suction pipe 606, the three-way valve 604, the gas supply pipe 603, and the connecting pipe 601. After the chamber reaches the preset vacuum level, turn off the vacuum pump 605, start the carbon dioxide delivery pump 607, and inject carbon dioxide into the fermentation chamber 201 through the carbon dioxide delivery pipe 608, the three-way valve 604, the gas supply pipe 603, and the connecting pipe 601. After the amount of carbon dioxide injected reaches the preset value, turn off the carbon dioxide delivery pump 607, the three-way valve 604, and the sealing valve 602 to complete the construction of the anaerobic environment, effectively inhibiting the growth of miscellaneous bacteria and ensuring the fermentation flavor.

[0035] Example 4 like Figure 6 As shown, based on the above embodiments, this embodiment provides a detailed description of the temperature and humidity control function and pickling method of the low-temperature fermentation chamber 3, and explains the specific operation and principle of each pickling step in conjunction with the device structure to ensure stable fermentation quality.

[0036] The core function of the low-temperature fermentation chamber 3 is to achieve precise temperature and humidity control of the fermentation environment. The externally mounted refrigeration unit 301 can adjust the temperature inside the chamber 3 according to instructions from the control terminal 304. The control terminal 304 can set temperature and humidity parameters for different fermentation stages and monitor temperature and humidity changes in real time. If temperature and humidity fluctuations occur, the refrigeration unit 301 will automatically adjust to ensure stable fermentation parameters. The vertical support 303 and the two-tiered placement rack 302 inside the low-temperature fermentation chamber 3 allow for the layered placement of the fermentation boxes 201, ensuring uniform ventilation and consistent temperature and humidity around each fermentation box, thus preventing uneven fermentation due to localized environmental differences.

[0037] Based on the above-mentioned pickling method using a pickling machine, the specific operating steps are as follows: Step 1: Material Preparation and Equipment Setup Equipment disinfection: Use aerosol disinfectant to thoroughly disinfect the pretreatment module (conveying shell 101, conveyor belt 103), packaging module (fermentation box 201, sealing cover 202) and all pipeline systems inside the pickling machine to eliminate initial bacterial contamination and ensure pickling safety.

[0038] Material processing and proportioning: Place the material to be marinated (such as fish) into fermentation box 201, and add auxiliary materials strictly according to the proportion. The amount of salt is 3% of the weight of the marinated product, and 1% of the weight of rice wine is added to assist fermentation, ensuring that the marinated product and auxiliary materials are fully mixed, laying the foundation for subsequent fermentation.

[0039] Pre-treatment piercing: Start the pre-treatment module 1, use the conveyor belt 103 to transport materials, and start the motor 5 to drive the needle plate 403 to reciprocate up and down to pierce the materials, so that the subsequent pickling liquid can fully penetrate into the materials and ensure uniform fermentation in all parts; during the piercing process, the impurity removal plate 406 can automatically remove the material residue attached to the needle plate to avoid cross-contamination.

[0040] Encapsulation and Anaerobic Treatment: The mixed auxiliary materials and punctured materials are sealed in the fermentation chamber 201, and the sealing cover 202 is put on. The sealing ring 203 is used to ensure the sealing performance. The ventilation chamber 6 is started, and the air in the fermentation chamber is extracted by the vacuum pump 605. Then, carbon dioxide is injected by the carbon dioxide delivery pump 607 to form an anaerobic fermentation environment to prevent the growth of miscellaneous bacteria from affecting the flavor.

[0041] Placement of fermentation box: The sealed fermentation box 201 is transported to the low-temperature fermentation room 3 by the movable wheels 609 and placed on the second-layer placement rack 302 to make reasonable use of space and ensure uniform ventilation around the fermentation box.

[0042] Step 2, Marinating Stage 1 (0 to 12 hours) Fermentation parameters are set via the control and adjustment terminal 304 within the low-temperature fermentation chamber 3, maintaining the fermentation environment temperature at 6-8℃ and humidity at 72-80%. During this stage, the difference in reproductive dominance between lactic acid bacteria and other microorganisms is minimal. These temperature and humidity parameters inhibit the growth of other microorganisms while promoting the active reproduction of lactic acid bacteria, decomposing the sugars in the pickled products and generating basic flavor compounds, laying the foundation for subsequent flavor shaping. During this process, the air pressure inside the fermentation chamber 201 is monitored in real-time via the air pressure sensor 206. If the air pressure is too high, it can be slowly released through the exhaust valve 205 to ensure stable air pressure within the fermentation chamber and prevent damage to the sealing structure.

[0043] Step 3, Marinating Stage Two (12 to 36 hours) After 12 to 36 hours of pickling, fermentation parameters are adjusted via control terminal 304 to maintain the fermentation environment at 0 to 4°C and 55 to 65% temperature and humidity. During this stage, lactic acid bacteria have multiplied significantly; lowering the temperature and humidity slows down the fermentation process, preventing over-fermentation that could lead to flavor loss and a deterioration in taste. It also further inhibits the growth of unwanted bacteria, ensuring stable product quality. Throughout this process, the temperature and humidity of the low-temperature fermentation chamber 3 and the air pressure within the fermentation box 201 are continuously monitored to ensure parameter stability. If temperature or humidity fluctuations occur, the refrigeration unit 301 and control terminal 304 will automatically adjust to ensure a controllable fermentation process.

[0044] Step 4: Finishing of Marinating and Subsequent Processing Fermentation complete: After the pickling time reaches 36 hours and the fermentation is confirmed to be complete, turn off the refrigeration unit 301 and control terminal 304 of the low-temperature fermentation room 3 to stop the fermentation process.

[0045] Unsealing and discharging: Remove the fermentation box 201 from the low-temperature fermentation room 3, slowly open the exhaust valve 205 to release the air pressure inside the box, remove the sealing cover 202, and take out the pickled material to obtain a pickled product with uniform flavor and safe and controllable quality.

[0046] Equipment cleaning: After removing the finished product, clean and disinfect the fermentation box 201, sealing cover 202, conveyor belt 103, needle plate 403 and other components, and clean the residual materials in the pipes to prepare for the next use and avoid the residual materials from deteriorating and affecting the subsequent pickling quality.

[0047] The pickling method in this embodiment strictly follows the structural features of the pickling machine. Through two-stage precise temperature and humidity control, combined with functions such as oxygen-free sealing, automatic impurity removal, and air pressure regulation, the pickling process is controllable and efficient, solving many drawbacks of traditional manual pickling and improving the quality and safety of pickled products.

[0048] Working principle of this invention: When using this device, during the process of conveying fish meat using the conveyor belt 103, the needle plate 403 processes the fish meat. The motor 5 is started, and the output of the motor 5 drives the rotating disk 501 to rotate. The rotating disk 501, in conjunction with the rotating shaft 503, drives the needle plate 403 to reciprocate up and down, causing the needle plate 403 to continuously pierce the fish meat. During the descent of the needle plate 403, the limiting plate 407 contacts the conveyor belt 103, causing the impurity removal plate 406 to stop contacting. At this time, the needles of the needle plate 403 pierce through the impurity removal plate 406 to process the fish meat. During the ascent of the needle plate 403, the impurity removal plate 406 removes any attached fish meat. When the impurity removal plate 406 moves, it drives the sliding rod 405 to slide within the mounting ring 404 and compress the return spring 408, thus ensuring that the impurity removal plate 406 returns to its original position under the drive of the return spring 408. The pierced fish meat is thoroughly mixed with the fermentation liquid in the fermentation box 201. After the fermentation box 201 is covered with the sealing cover 202, the bottom of the sealing cover 202... The pressure cage 204 of the fermentation chamber can press the fish meat into the fermentation liquid. The fermentation chamber 201 and the sealing cover 202 are sealed with a sealing ring 203. The pressure sensor 206 and the exhaust valve 205 can adjust when the internal pressure of the fermentation chamber 201 increases. In order to ensure an anaerobic environment in the fermentation chamber 201, the vacuum pump 605 and the carbon dioxide delivery pump 607 in the air exchange box 6 are used to first evacuate the fermentation chamber 201 and then inject carbon dioxide. The three-way valve 604, together with the air extraction pipe 606, the carbon dioxide delivery pipe 608 and the air supply pipe 603, transport and output the air in the fermentation chamber 201. The sealed fermentation chamber 201 is transported to the low temperature fermentation room 3 by the casters 609. The double-layer placement rack 302 and the vertical support 303 are used to increase the space utilization of the low temperature fermentation room 3. The refrigeration unit 301 and the control and regulation terminal 304 are used to detect and adjust the internal temperature of the low temperature fermentation room 3 to ensure that the fermentation temperature is controllable.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
