Description

Technical Field

[0001] This utility model belongs to the field of meat enzymatic hydrolysis processing technology, and in particular relates to a high-efficiency enzymatic hydrolysis reactor for oyster meat production. Background Technology

[0002] In the field of oyster meat processing, enzymatic hydrolysis is a key step in releasing the flavor and nutrition of oyster meat. Currently, when using reaction tanks for enzymatic hydrolysis, the high viscosity of the oyster meat paste after crushing causes the solid meat residue and liquid juice to easily separate due to density differences within the tank. This separation makes it difficult for the subsequently added protease to fully and evenly contact all the materials, resulting in a slow and inefficient enzymatic hydrolysis process, and potentially affecting the flavor uniformity of the final product. On the other hand, after the enzymatic hydrolysis reaction, heating is required to rapidly inactivate the protease. However, with the high viscosity of the oyster meat paste system, traditional heating and stirring methods often fail to achieve rapid and uniform heat transfer, easily causing localized overheating or underheating within the tank. This not only affects product quality but also restricts the overall production efficiency and stability. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency enzymatic hydrolysis reactor for oyster meat production. By vertically arranging a spiral conveying and stirring assembly and a heating tube inside the reactor, oyster meat paste to be enzymatically hydrolyzed is added to the reactor. The spiral conveying and stirring assembly then spirally conveys the oyster meat paste from the bottom of the reactor upwards, allowing it to fall back to the bottom. This achieves vertical mixing of the oyster meat and the added protease, preventing the oyster meat residue from separating from the oyster juice, which would result in uneven mixing of the protease. After enzymatic hydrolysis is complete, the heating tube is activated, heating the oyster meat paste while it is being stirred, achieving rapid temperature rise and enzyme inactivation, thus realizing high-efficiency enzymatic hydrolysis production of oyster meat.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a high-efficiency enzymatic hydrolysis reaction tank for oyster meat production, including a tank body, a tank cover, a spiral conveying and stirring assembly, and a heating tube. The spiral conveying and stirring assembly is vertically arranged inside the tank body, and the heating tube includes a set of annularly arranged serpentine tubes. The heating tube is sleeved on the outside of the spiral conveying and stirring assembly, and the tank cover is placed over the upper opening of the tank body.

[0005] A further feature of this invention is that the lower end of the tank tapers downwards, the lower end of the tank is open, and a discharge pipe head is provided on the lower end face of the tank, with a bottom cap spirally screwed inside the discharge pipe head.

[0006] A further feature of this invention is that a pressure relief valve is provided on the can lid.

[0007] A further feature of this invention is that the spiral conveying and mixing assembly includes an auger screw and a screw tube. The screw tube is vertically installed inside the tank, with a gap between the lower end of the screw tube and the bottom of the tank. The auger screw is sleeved inside the screw tube, and the lower end of the auger screw is rotatably mounted on the upper surface of the bottom cover. A drive motor is installed at the upper end of the tank cover, and the upper end of the auger screw penetrates the surface of the tank cover and is fixedly connected to the output end of the drive motor.

[0008] A further feature of this invention is that a sleeve is fixedly fitted onto the outer side of the screw tube, and a set of side plates are fixedly arranged in a circumferential array on the outer side wall of the sleeve, with the end of the side plate away from the sleeve fixedly connected to the inner side wall of the tank.

[0009] A further feature of this invention is that a material distribution ring support is fixedly installed at the upper end of the screw tube, and a material distribution edge is fixedly provided on the outer wall of the upper end of the material distribution ring support, with the edge of the material distribution edge inclined downward.

[0010] A further feature of this invention is that a diffuser ring tube is fixedly installed at the upper end of the bulk material ring support, and a set of injection heads are arranged in a circumferential array on the inner wall of the diffuser ring tube.

[0011] A further feature of this invention is that a sensor sleeve is fitted onto the lower end of the screw tube, and a temperature sensor and a pH sensor are provided on the outer wall of the sensor sleeve.

[0012] This utility model has the following beneficial effects: 1. This utility model uses a vertically arranged spiral conveying and stirring component to continuously lift and throw the oyster meat paste at the bottom of the tank, forming a strong vertical circulation flow. This effectively breaks the solid-liquid separation phenomenon caused by the viscosity of the material, allowing the protease and oyster meat paste to be mixed quickly and evenly in the tank, significantly improving the efficiency and uniformity of the enzymatic hydrolysis reaction.

[0013] 2. This utility model, by placing the annularly arranged serpentine heating tubes on the outside of the spiral conveying and stirring assembly, tightly integrates the heating area with the forced circulation path of the material. This enables rapid and uniform heating of the high-viscosity minced meat system during the enzyme inactivation stage, effectively avoiding the problems of local overheating or underheating, thereby ensuring the thoroughness of the enzyme inactivation effect and the stability of product quality.

Detailed Implementation

[0020] 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.

[0021] Example 1 Please see Figures 1 to 4 This utility model is a high-efficiency enzymatic hydrolysis reaction tank for oyster meat production, including a tank body 1, a tank cover 2, a spiral conveying and stirring assembly 3 and a heating tube 4. Through an innovative vertical circulation stirring system and an integrated heating device, it achieves efficient and uniform processing of oyster meat enzymatic hydrolysis. Tank 1 is a vertical container, and tank cover 2 is placed over the upper opening of tank 1. The spiral conveying and stirring assembly 3 is vertically arranged inside tank 1. The heating pipe 4 includes a set of annularly arranged serpentine pipes, which are sleeved on the outside of the spiral conveying and stirring assembly 3 to form a surrounding heating structure.

[0022] Specifically, the lower end of the tank 1 tapers downwards and the lower end of the tank 1 is open. A discharge pipe head 101 is fixed on the lower end face of the tank 1. A bottom sealing cover 101a is spirally screwed into the discharge pipe head 101. The conical tapered bottom design, combined with the spiral sealing bottom cover, realizes the complete emptying of materials and cleaning without dead corners, while ensuring the sealing reliability of the bottom of the tank and avoiding the risk of leakage during the enzymatic hydrolysis process.

[0023] Furthermore, a pressure relief valve 201 is installed on the tank cover 2. The pressure relief valve provides reliable safety protection. When abnormal gas pressure is generated during the enzymatic hydrolysis process, it can automatically release the pressure and stabilize the system working pressure within a safe range, effectively preventing the risk of overpressure operation of the equipment.

[0024] Furthermore, the screw conveyor mixing assembly 3 includes an auger screw 301 and a screw tube 302. The screw tube 302 is vertically installed inside the tank body 1, with a gap between the lower end of the screw tube 302 and the bottom of the tank body 1. The auger screw 301 is sleeved inside the screw tube 302, and the lower end of the auger screw 301 is rotatably installed on the upper end face of the bottom cover 101a. The upper end of the tank cover 2 is equipped with a drive motor 301a. The upper end of the auger screw 301 penetrates the surface of the tank cover 2 and is fixedly connected to the output end of the drive motor 301a. The vertical screw conveyor structure realizes the forced circulation of materials from the bottom to the top, with a circulation efficiency of 3-5 times per minute, completely eliminating the dead zone and stratification phenomenon existing in traditional mixing.

[0025] A sleeve 302a is fixedly sleeved on the outer side of the screw tube 302. A set of side plates 302a-1 are fixedly arranged in a circumferential array on the outer side wall of the sleeve 302a. The end of the side plate 302a-1 away from the sleeve 302a is fixedly connected to the inner side wall of the tank 1. The radial support structure ensures the stable operation of the stirring system, while enhancing the overall structural strength of the tank and extending the service life of the equipment under high-speed stirring conditions.

[0026] Furthermore, a material distribution ring support 302b is fixedly installed at the upper end of the screw tube 302. A material distribution edge 302b-1 is fixedly provided on the outer wall of the upper end of the material distribution ring support 302b. The edge of the material distribution edge 302b-1 is inclined downward. The inclined material distribution edge design allows the material lifted to the top to be evenly dispersed and fall, forming an umbrella-shaped distribution effect, which will improve the uniformity of material distribution and ensure the comprehensiveness and consistency of the enzymatic hydrolysis reaction.

[0027] Furthermore, a diffuser ring tube 302c is fixedly installed at the upper end of the bulk material ring support 302b. A set of injection heads 302c-1 are arranged in a circumferential array on the inner wall of the diffuser ring tube 302c. The ring-shaped distribution of injection heads enables the uniform addition of enzyme preparations, avoiding the problem of uneven enzymatic hydrolysis caused by excessive local concentration. At the same time, sodium bicarbonate solution or citric acid can be added to adjust the pH value of oyster meat paste.

[0028] Furthermore, a sensor sleeve 302d is fitted onto the lower end of the screw tube 302. A temperature sensor 302d-1 and a pH sensor 302d-2 are installed on the outer wall of the sensor sleeve 302d. The multi-point sensing system monitors key parameters in the enzymatic hydrolysis process in real time, providing reliable data support for process optimization.

[0029] The operation process of this embodiment is as follows: After the pre-treated oyster meat paste is placed into tank 1 and the tank lid 2 is sealed, the drive motor 301a is started to drive the auger screw 301 to rotate, continuously conveying the bottom material upwards and evenly scattering it downwards through the material distribution ring 302b, forming a strong vertical circulation flow; protease preparation is evenly added through the injection head 302c-1 on the distribution ring pipe 302c, achieving thorough mixing of enzyme and substrate during material circulation; the heating tube 4 precisely controls the enzymatic hydrolysis temperature within the optimal range of 45-55℃ based on feedback from the temperature sensor 302d-1; after enzymatic hydrolysis, the temperature is rapidly raised to 85℃ for enzyme inactivation treatment. During the process, the pH sensor 302d-2 monitors pH changes in real time to ensure a stable enzymatic hydrolysis environment. After the reaction, the bottom cover 101a is opened to discharge the product, and the equipment is automatically cleaned using a CIP cleaning system to prepare for the next batch of production. In this embodiment, a vertical spiral circulating stirring system is used to achieve efficient mixing of materials, breaking the stratification phenomenon present in traditional stirring. An integrated heating device ensures accurate temperature control, and a multi-point monitoring system provides data support for process optimization. This equipment has the advantages of high enzymatic hydrolysis efficiency, stable product quality, and low energy consumption, significantly improving the technical level and economic benefits of oyster meat deep processing.
