Description

TECHNICAL FIELD

[0002] In the fields of yellow rice wine, beverage processing, pharmaceuticals and biological engineering, sterilization treatment of liquid materials is a key link to ensure product hygiene and safety. Although traditional sterilization methods (such as pasteurization, high-temperature long-time sterilization, etc.) can effectively kill microorganisms, they are prone to damage heat-sensitive ingredients (such as vitamins, proteins, etc.), affecting the nutritional value and sensory quality of the product. Therefore, instant high-temperature sterilization technology has emerged, which can achieve efficient sterilization while maximizing the preservation of the original properties of the material by heating the material to a sterilization temperature (usually above 120℃) for a short time and then rapidly cooling it.

[0003] The existing instant sterilization equipment usually adopts a multi-stage heat exchange structure, which realizes heat energy recycling through the synergistic effect of preheating, heating and cooling modules to improve energy efficiency. However, such equipment still has the following technical problems in actual application:

[0004] 1. Insufficient temperature control accuracy: due to factors such as material flow state, heat exchange efficiency fluctuations, etc., the temperature of the heated material may deviate, and if it does not reach the sterilization temperature, it may lead to incomplete sterilization and pose a safety hazard.

[0005] 2. Low heat energy utilization rate: the heat exchange path design of the cold and hot media in traditional equipment is not reasonable, and the heat recovery in the preheating stage is not sufficient, resulting in energy waste.

[0006] 3. Poor equipment adaptability: for materials with high viscosity or uneven composition, the existing equipment has limited mixing and stirring capacity, making it difficult to ensure the uniformity of the material temperature and affecting the consistency of the sterilization effect.

When the temperature of the liquid does not reach the sterilization standard (e.g., above 120℃), the system automatically starts the stirring and mixing and reflux reheating functions to ensure that all liquids meet the sterilization requirements and avoid incomplete sterilization caused by temperature fluctuations.

[0039] 2. High-efficiency heat recovery reduces energy consumption. The cooling medium flows from bottom to top through the cooling and preheating components, first cooling the sterilized liquid and then preheating the initial liquid, achieving cascade utilization of heat energy and reducing the heat load on the heating components. The circulating heating of the heat medium, combined with a pressure pump, ensures a stable supply of high-temperature heat medium and reduces heat loss.

[0040] 3. Intelligent mixing and dynamic reflux enhance uniformity. The secondary pressurization unit integrates a clutch transmission mechanism and a stirring component. When the feed liquid temperature is detected to be below standard, the heated feed liquid is automatically mixed with the preheated feed liquid, and forced homogenization is achieved through stirring blades. This ensures uniform temperature distribution before reheating, preventing localized overheating or insufficient sterilization. The solenoid valve and clutch transmission mechanism work together to automate the switching between mixing, pressurization, and reflux without manual intervention, thus improving production efficiency.

[0041] 4. Modular compact design, easy to maintain, coaxial heat exchange components and pressurization components adopt nested structure, reduce pipeline redundancy, smaller equipment volume, suitable for production lines with limited space, coaxial driving of centrifugal impeller, single motor driving multi-stage pressurization, reduce mechanical complexity, reduce failure points, lower maintenance cost.

[0042] 5. Strong adaptability and high scalability, the application can be applied to liquid materials with different viscosity and composition, and can adapt to various sterilization process requirements by adjusting the temperature or flow rate of the heat exchange medium.

[0054] Embodiment 1

[0055] Please refer to Figure 1 , Figure 3 , Figure 5 , a temperature-controllable and adjustable instantaneous sterilization machine, comprising:

[0056] Three groups of heat exchange assemblies 1 are coaxially and sequentially distributed in the vertical direction, and the three groups of heat exchange assemblies 1 are used as preheating assemblies 101, heating assemblies 102 and cooling assemblies 103 respectively, and the heat exchange assemblies 1 are each provided with a medium passage 11 and a feed liquid pipeline 12;

[0057] A first-stage pressurizing assembly 201, a second-stage pressurizing assembly 202 and a third-stage pressurizing assembly 203 are coaxially and sequentially distributed in the vertical direction and are each used for pressurizing sterilization feed liquid, and the first-stage pressurizing assembly 201, the second-stage pressurizing assembly 202 and the third-stage pressurizing assembly 203 are connected with the feed liquid pipeline 12 in each group of heat exchange assemblies 1;

[0058] The stirring assembly 3 is integrated to the secondary pressurizing assembly 202, and when the sterilized liquid treated by the heating assembly 102 is insufficient to reach the sterilization temperature, the stirring assembly 3 is used to mix the sterilized liquid output by the heating assembly 102 and the preheating assembly 101, and the sterilized liquid is re-input into the heating assembly 102 under the pressurization of the secondary pressurizing assembly 202.

[0059] The clutch transmission mechanism is assembled between the secondary pressurizing assembly 202 and the stirring assembly 3, and is used to connect or disconnect the power connection posture of the stirring assembly 3 and the secondary pressurizing assembly 202.

[0060] The instant sterilization machine is generally used in the heating type sterilization process in food processing to instantaneously and efficiently sterilize the liquid food, so as to meet the hygiene and safety level requirements of food processing.

[0061] The food liquid subjected to sterilization treatment is sequentially passed through the liquid pipeline 12 in the preheating assembly 101, the heating assembly 102 and the cooling assembly 103 in a top-down flow, and the primary pressurizing assembly 201, the secondary pressurizing assembly 202 and the tertiary pressurizing assembly 203 can respectively pressurize the liquid input into the preheating assembly 101, the heating assembly 102 and the cooling assembly 103, so as to ensure the stable flow of the liquid in the liquid pipeline 12.

[0062] The cooling medium is input into the medium passage 11 in the cooling assembly 103 and the preheating assembly 101 from bottom to top, and the cooling medium is first fully heat-exchanged with the food liquid in the cooling assembly 103 to reduce the temperature of the food liquid to about 4℃ (or room temperature level) to meet the temperature requirements of the food liquid storage and transportation, and the temperature of the cooling medium is greatly increased and transmitted to the preheating assembly 101 to preheat the food liquid transmitted in the preheating assembly 101, so as to reuse the heat and reduce the difference between the food liquid and the sterilization temperature of the heating assembly 102, thereby improving the efficiency of the heating assembly 102 in heating the food liquid to the sterilization temperature.

[0063] The hot medium is input into the medium passage 11 in the heating assembly 102 from bottom to top, and the temperature of the hot medium is usually set to about 130℃ to fully heat-exchange with the food liquid flowing in the heating assembly 102, so as to increase the temperature of the food liquid to above 120℃ to achieve the treatment effect of instant sterilization.

[0064] When the temperature of the food material liquid output from the heating assembly 102 cannot reach the sterilization temperature, the food material liquid can be controlled to be input into the stirring assembly 3, and the food material liquid output from the upstream preheating assembly 101 is input together, the power of the secondary pressurizing assembly 202 is transmitted to the stirring assembly 3 by means of the clutch transmission mechanism, and the food material liquid is fully mixed and the temperature is balanced under the continuous stirring action of the stirring assembly 3. After the stirring assembly 3 completes the stirring operation, the food material liquid is re-input into the heating assembly 102, and after being heated again, the temperature reaches above the sterilization temperature.

[0065] When the food material liquid output from the heating assembly 102 is above the sterilization temperature, the food material liquid can be controlled to be input into the cooling assembly 103 on the downstream side, so that it is cooled to a set temperature level.

[0092] The liquid delivered by the preheating assembly 101 is delivered into the inlet cavity 211 of the second-stage pressurizing assembly 202 through the lower liquid ring pipe 161 at the bottom, and then is delivered into the heating assembly 102 through the upper liquid ring pipe 151 connected with the discharge cavity 212 after the pressurizing treatment of the centrifugal impeller 22.

[0093] The inlet cavity 211 of the third-stage pressurizing assembly 203 is in communication with the lower liquid ring pipe 161 of the heating assembly 102, the discharge cavity 212 of the third-stage pressurizing assembly is in communication with the upper liquid ring pipe 151 of the cooling assembly 103, and the lower liquid ring pipe 161 of the cooling assembly 103 is connected with the discharge ring pipe 82.

[0094] The material liquid processed by the heating assembly 102 is input into the feeding cavity 211 of the third-stage pressurizing assembly 203 through the bottom material liquid lower ring pipe 161, and after being pressurized by the centrifugal impeller 22, the material liquid is input into the cooling assembly 103 through the material liquid upper ring pipe 151 connected to the discharging cavity 212. The food material liquid cooled by the cooling assembly 103 is finally discharged through the bottom material liquid lower ring pipe 161 and the discharging ring pipe 82.

[0095] To ensure that the stirring assembly 3 can be stably assembled on the second-stage pressurizing assembly 202, and to realize the mixing, pressurizing and re-inputting of the material liquid whose temperature output by the heating assembly 102 does not meet the standard and the material liquid processed by the upstream preheating, the following technical solutions are provided.

[0096] The stirring assembly 3 includes a connecting cylinder 31, an overflow cylinder 32, a rotating sleeve 33, stirring blades 34 and a separation cylinder 35. The connecting cylinder 31 and the overflow cylinder 32 are both fixedly connected to the top of the assembly shell 21 of the second-stage pressurizing assembly 202. The connecting cylinder 31 is arranged at the periphery of the overflow cylinder 32. The assembly shell 21 of the second-stage pressurizing assembly 202 is provided with a feeding through hole 213 for connecting the feeding cavity 211 and the connecting cylinder 31. The bottom of the overflow cylinder 32 is provided with a discharging through hole 321 for connecting the connecting cylinder 31 and the overflow cylinder 32. The rotating sleeve 33 is sleeved to the periphery of the connecting shaft 221 and arranged in the overflow cylinder 32. The stirring blades 34 are fixedly connected to the outer wall of the rotating sleeve 33 and arranged in an annular array. The separation cylinder 35 is slidingly installed in the overflow cylinder 32 and rotationally connected with the rotating sleeve 33. The top end of the separation cylinder 35 is provided with a through hole 351.

[0097] The material liquid lower ring pipe 161 of the preheating assembly 101 is connected to the overflow cylinder 32. The material liquid lower ring pipe 161 of the heating assembly 102 is connected with a shunt pipe A 171 and a shunt pipe B 172. The shunt pipe A 171 is connected with the feeding cavity 211 of the third-stage pressurizing assembly 203. The shunt pipe B 172 is connected to the overflow cylinder 32. The shunt pipe A 171 and the shunt pipe B 172 are respectively provided with an electromagnetic switch valve A 173 and an electromagnetic switch valve B 174.

[0098] When the stirring assembly 3 is in the stop state and is not power connected with the secondary pressurizing assembly 202, the isolation cylinder 35 is at the stroke top end and does not cause the plugging of the discharging through hole 321, and at this time, the electromagnetic switch valve A 173 is in the open state and the electromagnetic switch valve B 174 is in the closed state, the liquid material heated by the heating assembly 102 can directly enter the tertiary pressurizing assembly 203 from the shunt pipe A 171 through the lower liquid ring pipe 161, and the output liquid material in the preheating assembly 101 can be directly delivered to the overflow cylinder 32 through the bottom liquid ring pipe 161, at this time, the liquid material input into the overflow cylinder 32 can enter the connecting cylinder 31 through the communication hole 351 and the discharging through hole 321, and then be delivered to the feeding cavity 211 in the secondary pressurizing assembly through the feeding through hole 213 for secondary pressurizing.

[0099] When the stirring assembly 3 is power connected with the secondary pressurizing assembly 202 and is in the running state, at this time, the isolation cylinder 35 is at the stroke bottom end and blocks the discharging through hole 321, and the electromagnetic switch valve A 173 is controlled to be in the closed state and the electromagnetic switch valve B 174 is controlled to be in the open state, the liquid material heated by the heating assembly 102 but not reaching the sterilization temperature can be input into the overflow cylinder 32 from the shunt pipe B 172 through the lower liquid ring pipe 161, and the output liquid material in the preheating assembly 101 can also be input into the overflow cylinder 32 through the matched liquid ring pipe 161, and when the rotating sleeve 33 drives the stirring blade 34 to rotate, the liquid material in the overflow cylinder 32 can be fully stirred and the temperature at each place can be in the same state. In the process of continuously filling the liquid material into the overflow cylinder 32, the uniformly mixed liquid material can overflow from the top end of the overflow cylinder 32 and enter the connecting cylinder 31, and finally enter the feeding cavity 211 in the secondary pressurizing assembly through the feeding through hole 213, so as to realize the secondary mixing and secondary pressurizing of the liquid material.

[0100] Since the isolation cylinder 35 is in sliding connection with the inner wall of the overflow cylinder 32 and is in rotating connection with the rotating sleeve 33, the rotating sleeve 33 in operation will not interfere with the isolation cylinder 35, but can drive the isolation cylinder 35 to rise and fall synchronously when the rotating sleeve 33 rises and falls, so as to realize the adjustment of the opening and closing state of the discharging through hole 321 at the bottom of the overflow cylinder 32.

[0101] It should be further pointed out that the support sleeve 9 is also fixedly assembled at the upper and lower ends of each heat exchange assembly 1, and the support sleeve 9 also includes an inner layer and an outer layer, so as to realize the stable assembly of each group of heat exchange assemblies 1 and ensure that each pipeline and each pressurizing assembly can be stably assembled in the heat exchange assembly 1.

[0102] Example 5

[0103] Please refer to Figure 8 , Figure 9In order to ensure that the clutch transmission mechanism can be stably installed between the two-stage pressurizing assembly 202 and the stirring assembly 3 and effectively adjust the power transmission posture, the following technical scheme is provided.

[0104] The top of the connecting cylinder 31 is fixedly connected with an assembly cover 311, the connecting shaft 221 is rotatably installed at the shaft center of the assembly cover 311, and the top end of the rotating sleeve 33 extends into the assembly cover 311.

[0105] The clutch transmission mechanism comprises a transmission sleeve 41, an axial bevel gear A 42, an axial bevel gear B 43, a radial bevel gear 44, an end face gear A 45, and an end face gear B 46 arranged in the assembly cover 311. The axial bevel gear A 42 and the axial bevel gear B 43 are fixedly connected with the connecting shaft 221 and the transmission sleeve 41 respectively and are symmetrically arranged. The transmission sleeve 41 is rotatably installed in the assembly cover 311 and is arranged below the axial bevel gear A 42. The radial bevel gear 44 is rotatably installed in the assembly cover 311 and is in meshing connection with the axial bevel gear A 42 and the axial bevel gear B 43. The end face gear A 45 is fixedly connected to the top end of the rotating sleeve 33. The end face gear B 46 is fixedly connected to the transmission sleeve 41 and is arranged below the end face gear A 45.

[0106] The assembly cover 311 can provide a sealed environment, thereby ensuring that the clutch transmission mechanism is stably assembled and operated therein. When the driving motor 7 drives the connecting shaft 221 and the axial bevel gear A 42 thereon to rotate, the radial bevel gear 44 can drive the axial bevel gear B 43 and the transmission sleeve 41 to stably rotate, and the transmission sleeve 41 and the connecting shaft 221 can be kept in reverse constant-speed rotation.

[0107] When the rotating sleeve 33 needs to be connected to the stirring assembly 3, the rotating sleeve 33 is controlled to move downward to the bottom end of the stroke. At this time, the isolation cylinder 35 can block the discharge through hole 321 and realize the nesting and locking of the end face gear A 45 and the end face gear B 46, and the transmission sleeve 41 can drive the rotating sleeve 33 to rotate synchronously.

[0108] In order to facilitate the adjustment of the lifting posture of the rotating sleeve 33 and the end face gear A 45 thereon and realize the control of power transmission or power cut-off to the stirring assembly 3, the following technical scheme is provided.

[0109] The clutch transmission mechanism further comprises a support ring seat 47 and an electric telescopic cylinder 48. The support ring seat 47 is in rotational connection with the end face gear A 45. The electric telescopic cylinder 48 is fixedly installed in the assembly cover 311 and is arranged in the vertical direction. The movable end of the electric telescopic cylinder 48 is fixedly connected with the support ring seat 47.

[0110] During the telescopic movement of the electric telescopic cylinder 48, the support ring seat 47 can be driven to move up and down along the vertical direction, and then drive the face gear A 45 and the rotating sleeve 33 to move up and down synchronously. Since the support ring seat 47 and the face gear A 45 are rotationally connected, when the face gear A 45 and the rotating sleeve 33 rotate synchronously with the face gear B 46, the support ring seat 47 and the electric telescopic cylinder 48 will not be interfered by the space movement.
