Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a meat reaction vessel. Background Technology

[0002] The following are typical technical problems encountered in the practical application of existing meat processing reactors:

[0003] The stirring spacing is not adjustable, resulting in poor adaptability: The stirring components of traditional reactors are mostly fixed structures, and the spacing between the stirring discs cannot be changed. When processing materials with high muscle fiber content (such as beef with tendons or whole chicken skeletons), the fixed spacing makes it difficult to form sufficient axial convection, and the materials are prone to sticking together and clumping, resulting in uneven mixing; while when processing materials with low fiber content (such as skinless chicken breast), the fixed high stirring intensity will cause unnecessary energy waste.

[0036] In addition, the reactor body 101 can be equipped with a readily available and mature temperature detector to monitor the temperature inside the reactor body 101. By controlling the temperature change, the input temperature of the external steam source can be adjusted (the adjustment method is a readily available and mature technology, and is not the inventive point of this utility model, so it will not be described in detail here).

[0037] The working principle is as follows:

[0038] I. Pretreatment Stage: Material Preparation and Parameter Measurement

[0039] Material crushing pretreatment

[0040] For reactants (whole chicken, bone-in beef, pork bones, etc.), they are first crushed into 2-5cm blocks by a crusher (the particle size must match the spacing of the mixing discs to avoid jamming due to excessive size or excessive splashing due to excessive size), to ensure that the material can smoothly enter the reactor body 101 through the material inlet 105, while reducing the load impact in the initial stage of mixing.

[0041] Muscle fiber content detection (existing mature technology)

[0042] Take 3-5 samples of the pulverized material (100-200g each) and determine the muscle fiber content using a fiber analyzer: first, remove the moisture from the sample by drying, then separate the fiber components using a neutral detergent and weigh them to calculate the fiber percentage. The core of this step is to provide data for subsequent adjustment of the stirring spacing—the muscle fiber content directly affects the material's flowability. A high fiber percentage makes the material prone to sticking and clumping, requiring stronger convection stirring; a low fiber percentage results in good material flowability, allowing for reduced stirring intensity to save energy.

[0043] II. Core Adjustment Stage: Precise Adaptation of Stirring Spacing

[0044] Locking and unlocking operations

[0045] The operator pulls the ring 405 of the locking structure 400, which causes the pin rod 402 to compress the spring 404 and move it out of the locking hole 306 of the first sleeve 305, thus releasing the vertical locking of the second stirring assembly 300. The pre-compression design of the spring 404 ensures automatic reset during subsequent locking, avoiding manual pushing and improving operational safety and efficiency.

[0046] Dynamic spacing adjustment

[0047] The hydraulic telescopic rod 302 is activated, which drives the sliding plate 301, the first sleeve 305, the second sleeve 307 and the second stirring plate 308 to move vertically as a whole with an accuracy of 5-10 mm / step. During the process, the first slider 303 slides along the first guide groove 209 and the second slider 304 slides along the second guide groove 210, which forcibly constrains the second stirring plate 308 to move only in the vertical direction, so as to avoid uneven stirring or collision with the inner wall of the reactor body 101 due to deviation.

[0048] Adjust the spacing based on the fiber content threshold:

[0049] When the fiber (muscle fiber, the same below) accounts for ≥15% (such as beef with tendons, whole chicken skeleton): adjust the spacing to 0.6-0.8 times the diameter of the disc (e.g., when the disc diameter is 500mm, the spacing is 300-400mm). By reducing the spacing, the axial convection intensity is enhanced, and the material caking is broken.

[0050] When the fiber content is <15% (such as skinless chicken breast or minced pork): adjust the spacing to 1.2 times the disc diameter** (e.g., when the disc diameter is 500mm, the spacing is 600mm) to reduce ineffective contact between the mixing components and the materials, and reduce the energy consumption of motor 201 (actual measurements show that it can save 15%-20% of energy).

[0051] Locking and fixing

[0052] After the spacing is adjusted to the correct position, release the pull ring 405. The spring 404 pushes the baffle 403 and the pin rod 402 to reset, so that the end of the pin rod is inserted into the corresponding locking hole 306, thereby achieving rigid locking of the second stirring component 300. This ensures that the spacing will not loosen due to vibration during the stirring process (the speed is usually 150-300 rpm), thus avoiding insufficient mixing of materials.

[0053] III. Reaction Operation Stage: Synergistic Effect of Stirring and Heating

[0054] Synchronous stirring mechanism

[0055] Start the motor 201, and its output end drives the rotating shaft 203 to rotate through the coupling 202, thereby synchronously driving the first mixing plate 204, the top plate 205, the second sleeve 307, and the second mixing plate 308 to rotate (the speed is adjusted according to the material characteristics: 150-200 rpm for materials with aggregate, and 250-300 rpm for materials without aggregate).

[0056] Because the first disc 2042 and the second disc 3082 are tilted in opposite directions (30°-60° acute angle opposite), bidirectional axial convection is generated when they rotate: the first stirring disc pushes the lower material to flow upward, and the second stirring disc pulls the upper material to circulate downward, forming the material to roll up and down in the kettle, avoiding local material to settle at the bottom of the kettle (which is prone to scorching due to overheating).

[0057] The serrations (2044, 3084) on the outer surfaces of the first stirring plate 2043 and the second stirring plate 3083 can cut the adhering fascia and meat chunks, especially for sinewy meats (such as beef shank and chicken skin), which can break up fiber bundles and improve the uniformity of materials and the efficiency of subsequent reactions (such as stewing and flavor substance extraction).

[0058] Precise heating control

[0059] An external steam source (pressure 0.2-0.4MPa) is introduced into the spiral heating tube 109 inside the circumferential wall of the reactor body 101 through the second valve 110 (the spiral arrangement ensures uniform circumferential temperature inside the reactor). When the steam flows inside the heating tube, it releases heat, raising the temperature inside the reactor to 105-121℃ (depending on process requirements: 105-110℃ for stewing, 115-121℃ for high-pressure extraction). The condensate after heat exchange flows back to the steam source through the third valve 111, forming a closed loop and reducing energy waste.

[0060] The heat insulation layer 102 (usually made of aluminum silicate cotton) on the outside of the reactor body can control the heat loss rate to within 5%, maintain the stable temperature inside the reactor, and avoid the meat from becoming tough due to temperature fluctuations (such as undercooking when the temperature is too low, or the meat becoming dry when the temperature is too high).

[0061] Sealing and anti-stick protection

[0062] The Y-shaped sealing ring 309 at the end of the second sleeve 307 is tightly attached to the outer peripheral wall of the rotating shaft 203 to form a dynamic seal, preventing soup and grease in the pot from seeping into the gap between the rotating shaft and the sleeve, thus avoiding equipment corrosion and material contamination.

[0063] The 5-10μm food-grade polytetrafluoroethylene nano-coating sprayed on the outer surfaces of the rotating shaft 203, the first stirring plate 204, and the second stirring plate 308 inside the reactor has both anti-stick and wear-resistant properties: on the one hand, it reduces the adhesion of meat (especially fatty pork belly and beef) to the stirring components, ensuring that the materials fully participate in the reaction; on the other hand, the coating thickness is controlled at 5-10μm (too thin and it will be easily worn due to stirring friction, too thick and it will affect the rigidity of the stirring plate), taking into account both practicality and equipment life.

[0064] IV. Final Stage: Material Discharge and Equipment Maintenance

[0065] Material discharge

[0066] After the reaction is complete (the stirring and heating time is adjusted according to the amount of material: 30-45 minutes for 10-30kg of material, and 45-60 minutes for 30-50kg of material), turn off the motor 201 and the steam source, and open the first valve 107 of the material outlet 106 to allow the reacted material (such as stewed meat and bones, or flavored broth) to be discharged naturally. Due to the design of no dead corners at the bottom of the vessel (the first stirring plate is close to the bottom of the vessel, with an inclination angle of 30°-60° to facilitate the material to converge towards the outlet), the residual amount of material can be controlled to within 1%.

[0067] Equipment cleaning

[0068] After discharging the material, introduce clean water into the vessel (through material inlet 105), and start motor 201 to stir at low speed (50-100 rpm) for 3-5 minutes. Use the serrated edge of the stirring plate and the water flow to rinse the inner wall and stirring components. Due to the non-stick properties of the PTFE coating, rinsing with clean water is sufficient to remove residual material without the need for detergent, meeting the hygiene requirements of food-grade equipment. At the same time, close the second valve 110 and open the third valve 111 to introduce clean water into the heating tube 109 for reverse rinsing to remove residual scale inside the tube and prevent blockage that could affect the efficiency of the next heating cycle.
