Description

Technical Field

[0001] This invention relates to the field of processing technology for medicinal and edible homologous extracts, specifically to a high-temperature sterilization equipment for mixing medicinal and edible homologous extracts and its processing method. Background Technology

[0002] This medicinal and edible essence liquid uses nationally recognized medicinal and edible herbal ingredients as raw materials. Following traditional health preservation concepts, it is scientifically formulated and refined. Using low-temperature extraction and concentration purification processes, it fully preserves the active nutrients and natural herbal essences of the ingredients, removes impurities and redundant components, and has a rich, easily absorbed liquid texture. The product contains few additives, is mild and safe, and has both dietary supplementation and daily nourishment effects. It can be drunk directly or diluted with water. It can gently regulate the body's condition and supplement the nutrients needed for daily life. It is suitable for the daily health preservation and constitution conditioning needs of various groups and is a preferred natural functional liquid tonic for modern health preservation.

[0003] In the prior art, the technical solution of a mixing device for processing concentrated liquid, such as the mixing device for fragrant plant essences with application number 202420565765.9, is as follows: it includes an adjusting sleeve, and a mixing box is provided inside the adjusting sleeve. The mixing box has openings on both sides. Feed pipes opposite to the openings are provided on both sides of the adjusting sleeve. A pipe mesh is fixed between the inner walls of the mixing box. The pipe mesh is woven together by interconnecting small pipes. Multiple connecting pipes are provided at the bottom of the pipe mesh. An air supply pipe is provided between the bottoms of the multiple connecting pipes.

[0004] The medicinal and edible homology extract is made from a variety of medicinal and edible herbal raw materials, rich in natural active ingredients and medicinal substances. It is extremely sensitive to sterilization temperature. Existing sterilization equipment mostly adopts direct instantaneous high-temperature sterilization, which cannot achieve gradual sterilization of raw materials by gradient temperature increase. Sudden high temperature can easily destroy the active nutrients and effective medicinal components in herbal raw materials, resulting in loss of efficacy and decline in quality. At the same time, conventional high-temperature sterilization heat recovery structure is simple, with a large amount of heat loss and no heat energy recycling. This results in high energy consumption and low resource utilization, which not only affects the quality of the extract product, but also increases the energy consumption cost of production, making it difficult to meet the sterilization production requirements of high-quality medicinal and edible homology extract.

[0005] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0006] To address the aforementioned issues, an innovative design was implemented based on the existing concentrate mixing equipment. Summary of the Invention

[0007] The purpose of this invention is to provide a high-temperature sterilization equipment and processing method for mixing medicinal and edible homologous essence liquids, in order to solve the problems of loss of efficacy and high energy consumption costs in the above-mentioned background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A high-temperature sterilization mixing device for medicinal and edible homologous extracts includes a mixing tank shell, with support legs at the bottom and a tank cover at the top. A discharge port is connected to the bottom of the mixing tank shell via a valve. A controller is located on the front side of the mixing tank shell. The mixing tank shell includes a mixing inner tank, and a heating chamber is provided between the mixing tank shell and the mixing inner tank. Several raw material tanks are located above the interior of the mixing inner tank. Several waste heat recovery components are fixedly installed on the outside of the mixing tank shell. Each waste heat recovery component includes an exhaust pipe connected to the top of a corresponding raw material tank. Each raw material tank has an inlet pipe connected to its top. A geared motor assembly is installed on the top of the mixing tank shell, and a stirring assembly is connected below the geared motor assembly. The stirring assembly includes a first stirring element and a second stirring element. The geared motor assembly includes a first motor and a second motor, with the first motor driving the first stirring element to rotate and the second motor driving the second stirring element to rotate.

[0010] Preferably, an electric heating tube is arranged in a spiral pattern inside the heating chamber, and an oil inlet is fixedly installed on the outer side of the mixing tank shell. Heat transfer oil is added into the heating chamber through the oil inlet. A temperature sensor is installed inside the mixing tank, and the temperature sensor signal is connected to a controller. The controller is used to control the electric heating tube to adjust the temperature.

[0011] Using the above technical solution, a rotating electric heating tube is used to heat the heat-conducting oil in the heating chamber. Combined with the oil inlet hopper, uniform heat conduction is achieved. This allows for gentle, stable, and localized high-temperature sterilization of the mixing tank without localized overheating. This avoids the damage of the active ingredients of the food-medicine homologous raw materials caused by sudden high temperatures. The temperature sensor collects the temperature inside the tank in real time and transmits it to the controller to achieve precise temperature control and automatic constant temperature. This ensures that the sterilization temperature remains stable within the optimal range, achieving thorough sterilization while preserving nutrients and medicinal components to the greatest extent, thus improving the quality of the concentrate.

[0012] Preferably, the waste heat recovery assembly includes a waste heat recovery box, which is fixedly installed on the outside of the mixing tank shell, and an air inlet pipe is connected to the inner end of the waste heat recovery box.

[0013] Using the above technical solution, the waste heat recovery box is fixed on the outside of the mixing tank shell. It has a compact structure and does not take up extra space. It directly collects the waste heat gas in the upper part of the heating chamber through the air inlet pipe, and concentrates and recovers the heat that was originally lost in the sterilization process, thus avoiding energy waste. As a transfer and buffer structure, the waste heat recovery box can stabilize the airflow and balance the heat, providing a continuous and gentle heat source for the subsequent preheating of the raw material tank, realizing the cascade utilization of heat energy and reducing the overall energy consumption of the equipment.

[0014] Preferably, the air inlet pipe is connected to the inside of the heating chamber, and the height of the air inlet pipe is higher than the highest plane of the heat transfer oil. An air pump is installed above the waste heat recovery box, and an air outlet pipe is connected above the air pump.

[0015] Using the above technical solution, the air inlet pipe is set above the oil level, which can collect only hot air without allowing oil to enter, protecting the pipeline from blockage and oil leakage. The air pump provides a stable negative pressure, and the waste heat airflow is stably sent into the raw material tank through the air outlet pipe. The airflow speed and heat output are uniform, which can gently preheat the raw material liquid, avoiding the raw material from being damaged by thermal shock. The waste heat transfer is stable and controllable, and the preheating efficiency is high, laying the foundation for low-temperature sterilization.

[0016] Preferably, each of the raw material tanks is equipped with a cover, and each of the raw material tanks has a discharge end at the bottom, and the air outlet pipes all pass through the cover.

[0017] The above technical solution is adopted. The raw material tank is equipped with a cover to reduce heat loss, prevent dust and impurities from entering, and ensure the hygiene of the raw materials. The feeding end is precisely controlled and the feeding is uniform and stable, which facilitates accurate feeding according to the formula ratio. The vent pipe passes through the cover and directly delivers residual heat into the tank. The preheating and low-temperature sterilization effects are direct and efficient, so that the raw materials are pre-treated before entering the main tank, thereby improving the overall processing efficiency.

[0018] Preferably, the lower output end of the second stirring component is connected to a first rotating shaft, and a gear ring is fixedly connected to the upper outer side of the first rotating shaft by a bracket. The inner side of the gear ring is meshed with several driven gears, and the driven gears are rotatably connected to the upper part of the cover.

[0019] Using the above technical solution, the second stirring component drives the first rotating shaft and gear ring to rotate, synchronously driving multiple driven gears to rotate, realizing the single power to drive the stirring of multiple sets of raw material tanks. The structure is simple, the power utilization rate is high, the operation synchronization is good, the gear meshing transmission is stable and does not slip, and it can drive the rotating rod to continuously stir the raw materials, so that the raw materials are heated evenly, avoiding local overheating, ensuring that the preheating and low temperature sterilization effects are consistent, and improving the quality of raw material pretreatment.

[0020] Preferably, each driven gear is fixedly connected to a rotating rod below it, and several sets of stirring rods are fixedly installed on the outside of the rotating rod.

[0021] Using the above technical solution, the driven gear drives the rotating rod and stirring rod to rotate in the raw material tank, and gently stirs the raw material at a low speed. This allows the residual heat to be evenly diffused to all raw material liquids, achieving full-area low-temperature sterilization, eliminating sterilization dead zones, and the stirring action is gentle and does not damage the active ingredients of the raw materials. At the same time, it prevents the raw materials from settling and ensures uniform composition, providing stable and consistent raw materials for subsequent mixing processes and improving the quality of the final product.

[0022] Preferably, a first stirring component is fixedly connected below the first rotating shaft, and the first stirring component includes a stirring bracket. The bottom shape of the stirring bracket is adapted to the inner conical surface of the bottom of the mixing tank shell. Several stirring plates are symmetrically arranged on the inner side of the stirring bracket, and several first scrapers are obliquely installed on the left and right sides of the outer side of the stirring bracket. Several second scrapers are obliquely installed on the lower outer side of the stirring bracket.

[0023] Using the above technical solution, the first stirring component adopts a stirring bracket that fits the conical surface of the tank bottom, and works with the stirring plate to achieve strong mixing at the bottom and middle. The first scraper and the second scraper rotate closely against the tank wall, scraping off the material adhering to the wall throughout the process, avoiding residue, deterioration and contamination, ensuring that the material participates in the mixing, improving the cleanliness of the discharge, and the overall stirring is without dead corners and the mixing is uniform, which is suitable for the stable processing of high viscosity refined liquid.

[0024] Preferably, a second rotating shaft is nested inside the first rotating shaft, and the upper part of the second rotating shaft is connected to the output end of the second motor, and the lower part of the second rotating shaft is connected to a second stirring component. The second stirring component includes a plurality of rotating disks, and the outer edge of the rotating disks is provided with a plurality of shearing blades with different inclinations.

[0025] Using the above technical solution, the first and second rotating shafts are nested with a differential speed design. The turntable and multi-angle shear blades of the second stirring element can form high-speed shearing and turbulent disturbance, forming a complementary and strong-weak mixing field with the first stirring element. The differential rotation can quickly disperse agglomerates and achieve precise homogenization of multiple components, so that different extracts can be quickly and evenly fused, improving mixing efficiency and product stability, and ensuring that the composition of each batch is consistent.

[0026] Preferably, the processing method includes the following steps: placing various medicinal and edible homologous raw liquids into corresponding raw material tanks, sterilizing them at high temperature through a heating chamber and electric heating tubes, preheating the raw material tanks by introducing the waste heat from the heating chamber through the exhaust pipe using a waste heat recovery box to achieve heat energy recovery, and when the geared motor assembly is started, the first rotating shaft drives the gear ring to drive the driven gear to rotate, realizing the initial stirring and low-temperature sterilization of the raw materials by the stirring rod. After the pretreated raw materials are mixed, the geared motor assembly drives the first stirring piece and the second stirring piece to rotate at a differential speed, and the stirring plate and shearing blade complete the homogeneous mixing of the whole area. The rotation of the first scraper and the second scraper prevents the material from sticking to the wall. The sterilization temperature is controlled in real time by a temperature sensor to achieve integrated continuous processing of preheating, high-temperature sterilization, homogeneous mixing and waste heat recovery.

[0027] Using the above technical solution, the heating chamber provides a high-temperature sterilization heat source, and the waste heat recovery system introduces hot air into the raw material tank to achieve preheating and low-temperature sterilization, protecting the active ingredients of the raw materials. The raw material tank has its own stirring to achieve uniform pretreatment. The main tank adopts internal and external dual-shaft differential stirring, which can achieve full-area mixing, no dead corners, and no wall adhesion. The equipment integrates preheating, low-temperature sterilization, high-temperature sterilization, homogenization mixing, and waste heat recovery. It has the advantages of energy saving and high efficiency, complete retention of components, uniform mixing, and hygiene and safety. It is suitable for the automated production of high-quality medicinal and food homologous essence liquid.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the high-temperature sterilization medicinal and edible homologous essence mixing equipment and its processing method,

[0029] 1. Independent pretreatment of raw materials, gradient heating, protection of activity, and more stable quality: This equipment is equipped with multiple independent raw material tanks to realize separate storage, independent pretreatment, and precise proportioning of medicinal and edible homologous raw materials. This avoids cross-contamination of raw materials from the source. Before entering the main mixing tank, each raw material is preheated, sterilized at low temperature, and uniformly stirred in the tank to form a gradient heating mode, avoiding the loss of active ingredients caused by sudden high temperature shock. Independent pretreatment can flexibly adjust the temperature and time according to the characteristics of different raw materials to maximize the preservation of herbal essence, nutrients, and medicinal components, making the taste, color, and efficacy of the final extract more stable. Multiple tanks can operate simultaneously to process multiple formula raw materials at the same time, shortening the overall processing cycle and improving production efficiency. It is especially suitable for the production of multi-component compound medicinal and edible homologous extracts.

[0030] 2. Waste heat recovery preheating and low-temperature sterilization: energy saving, gentle sterilization, and protection of components. This equipment recovers the waste heat from the heating chamber sterilization through a waste heat recovery component and sends it to the raw material tank to achieve the dual functions of preheating and low-temperature sterilization, significantly reducing energy consumption. The waste heat airflow is gentle and uniform, performing low-temperature long-term sterilization on the raw materials. It can kill harmful microorganisms without damaging heat-sensitive nutrients, solving the problem of efficacy loss caused by traditional high-temperature instantaneous sterilization. The entire system realizes a closed loop of waste heat collection, transportation, and utilization, with a high thermal energy recycling rate. Compared with traditional equipment, it can significantly reduce power consumption and heating costs. At the same time, the preheated raw materials can reach the sterilization temperature more quickly after entering the main tank, shortening the high-temperature processing time and further improving the component retention rate, achieving a win-win situation of energy saving and quality preservation.

[0031] 3. Dual-shaft differential speed mixing, full-area mixing, no dead corners, no wall adhesion, and high homogeneity: This equipment adopts a dual-shaft differential speed mixing structure with a first and second mixing element, forming a strong shear and full-area circulation composite flow field to achieve efficient and homogeneous mixing of the refined liquid. The outer low-speed large mixing element is responsible for overall circulation and wall scraping to prevent wall adhesion, residue, and accumulation. The inner high-speed mixing element provides shear turbulence to quickly disperse agglomerates and make the multi-component liquids instantly and uniformly blended. The nested dual-shaft structure saves space, is highly efficient, and ensures no dead corners, no stratification, and no sedimentation, ensuring that every drop of product has uniform composition. The scraper structure cleans the tank wall throughout the process to avoid material residue and deterioration, ensuring production hygiene and product purity. It is especially suitable for the large-scale production of medicinal and edible homologous refined liquids with high quality and high homogeneity requirements. Attached Figure Description

It directly collects the waste heat gas from the upper part of the heating chamber 7 through the air inlet pipe 902, concentrating the heat originally lost during the sterilization process back into the heat recovery system. To avoid energy waste, the waste heat recovery box 901, acting as a transfer and buffer structure, can stabilize airflow and balance heat, providing a continuous and gentle heat source for the subsequent preheating of the raw material tank 10, realizing the tiered utilization of heat energy and reducing the overall energy consumption of the equipment.

[0052] Working principle:

[0053] In use, different medicinal and edible homologous extracts are added to their respective raw material tanks 10 through the feed pipe 11. The cover 1001 is sealed to maintain hygiene. Heat transfer oil is added to the heating chamber 7 through the oil inlet 8. The electric heating element 701 is activated to heat the heat transfer oil, preparing the mixing tank 6 for heating. Simultaneously, the residual heat gas in the upper part of the heating chamber 7 enters the waste heat recovery box 901 through the air inlet pipe 902. The air pump 903 sends the hot gas into each raw material tank 10 through the air outlet pipe 904 for gentle preheating and low-temperature sterilization of the raw materials. The first motor 1201 in the geared motor assembly 12 drives the first rotating shaft 13 and gear ring 14 to rotate, synchronously driving all driven gears 15, rotating rods 16 and stirring rods 17 to rotate, performing low-speed homogenization of the raw materials in the raw material tanks 10. The raw materials are stirred evenly to ensure uniform heating and thorough sterilization, while preventing sedimentation. After pretreatment, the raw material tank 10 is precisely fed into the mixing tank 6 from the bottom discharge end 1002 according to the formula ratio. At this time, the first motor 1201 and the second motor 1202 rotate at different speeds: the first stirring element 20 circulates at low speed, the stirring plate 2002 pushes the overall material flow, and the first scraper 2003 and the second scraper 2004 scrape the wall to prevent sticking; the second stirring element 21 rotates at high speed, and the shearing blade 2102 generates strong shear turbulence, which quickly achieves homogeneous mixing of multiple components throughout the entire area. During the mixing process, the temperature sensor monitors the temperature inside the tank in real time, and the controller 5 automatically adjusts the power of the electric heating tube 701 to maintain a stable high-temperature sterilization temperature and complete the final sterilization. After processing, the material is discharged from the discharge port 4.
