Description

TECHNICAL FIELD

[0001] The utility model relates to traditional Chinese medicine extraction technical field, specifically is medicinal material concentration's heating device. BACKGROUND

[0002] In the modernization production process of Chinese patent medicine, the concentration treatment of traditional Chinese medicine extract is one of the key links, which aims to reduce the volume of extract and improve the concentration of effective components to meet the subsequent preparation process requirements. At present, the industry generally uses concentration devices to achieve this goal, and heating is an indispensable operation method in the concentration process.

[0003] The current heating methods mainly include gas heating, water bath heating and steam heating. Although gas heating has certain advantages in heating rate, the heat distribution is uneven, the extract near the combustion part is heated rapidly, while the area far away is heated slowly. This significant temperature difference leads to poor overall heating uniformity, making the reaction process of each part of the medicinal material extract different during concentration, and unable to achieve ideal concentration effect. Steam heating also has similar problems, the temperature around the steam injection point is high, and the heat gradually decreases during the diffusion process, causing uneven heating of the extract, which is not conducive to precise control of the concentration process.

[0004] Water bath heating method can ensure relatively stable and uniform heating environment in principle, to some extent, avoiding the disadvantages of local overheating or overcooling. However, the heating tank in the traditional design is usually vertical, and the heating source is usually arranged at the bottom. In this layout, the heat is transferred from bottom to top, the bottom liquid is first exposed to high temperature, and is in high temperature state for a long time, which is easy to cause local overheating. It will cause imbalance of different component extraction and concentration rate, resulting in uneven quality of Chinese patent medicine.

[0005] In summary, the existing Chinese patent medicine extract concentration heating technology, whether it is uneven heating of gas and steam, or local overheating problem caused by vertical water bath heating tank, all need an innovative solution to optimize the concentration link in Chinese patent medicine production and ensure the stability and reliability of product quality. INVENTION CONTENTS

[0006] Therefore, to address the aforementioned shortcomings, this utility model provides a heating device for concentrating medicinal materials. This device comprises an outer tank and an inner tank, with the tanks positioned horizontally to facilitate the placement of the medicinal material extract into the inner tank. A heating liquid is circulated between the outer and inner tanks, heating the interior of the inner tank through heat conduction, thereby concentrating the medicinal material. This heating method can employ water bath heating to ensure uniform heating. Furthermore, the horizontal arrangement ensures sufficient flow of the heating liquid between the inner and outer tanks, guaranteeing simultaneous heating of all areas of the inner tank and avoiding the defects associated with localized heating. Additionally, the inclusion of a stirring mechanism further enhances the quality of the concentration.

[0007] This invention is achieved by constructing a heating device for concentrating medicinal materials, including an outer tank that is horizontally supported by a support.

[0008] The inner tank is fixed inside the outer tank and contains the herbal extract.

[0009] The stirring mechanism has one end located inside the inner tank to stir the medicinal extract inside, and the other end extends to the outer end of the outer tank.

[0010] A heating liquid for heating the inner tank is introduced into the gap between the outer tank and the inner tank.

[0011] Preferably, the outer tank is composed of an upper tank and a lower tank, which are spliced ​​together and kept fixed and sealed. The lower tank is fixed to the support on the outside. A limiting groove plate coaxial with the lower tank is provided at the bottom inside the lower tank. A slot is provided on the first limiting groove plate along the axial direction of the outer tank. A limiting plate that is engaged with the limiting groove is provided on the outside of the inner tank. A locking block that engages with the slot is provided on the outer end of the limiting plate.

[0012] Preferably, the lower tank of the outer tank has an upwardly extending discharge port inside, and a discharge pipe corresponding to the position of the discharge port is provided on the outside of the lower tank. The bottom of the inner tank has a discharge pipe corresponding to the position of the discharge port and inserted into the discharge port. The discharge pipe is conical to ensure a seal after being inserted into the discharge port.

[0013] Preferably, the top of the upper tank of the outer tank is provided with a first sleeve and a second sleeve, and the inner tank is provided with a liquid level rod and an exhaust pipe passing through the first sleeve and the second sleeve. The liquid level rod is used to detect the liquid level height inside the inner tank, and there is a gap between the exhaust pipe and the second sleeve.

[0014] Preferably, an outlet pipe and an inlet pipe are respectively provided above and below the end of the outer tank, and both the outlet pipe and the inlet pipe are in communication with the interior of the outer tank.

[0015] Preferably, the agitation mechanism includes an agitator rod and agitator blades. One end of the agitator rod is disposed outside the outer tank, and the other end passes through the outer tank and the end of the inner tank and is inserted into the inner tank to maintain a rotatable connection. The agitator rod and the inner tank are coaxially arranged, and the agitator blades are evenly installed on the agitator rod inside the inner tank.

[0016] This utility model has the following beneficial effects:

[0017] 1. Improved Heating Uniformity: This heating device employs an outer and inner tank structure, with the tanks placed horizontally. Combined with a water bath heating method, this allows the heating liquid to flow freely between the outer and inner tanks, ensuring that heat is evenly distributed throughout the inner tank via thermal conduction, simultaneously heating the herbal extract. This significantly improves heating uniformity, ensuring that all components are concentrated at a stable and balanced temperature, avoiding concentration differences caused by temperature variations.

[0018] 2. Optimize Concentration Quality: The heating device, with its horizontal tank layout and stirring mechanism, ensures that the heated liquid flows without dead zones, preventing localized heat accumulation and localized heating. On the other hand, the stirring mechanism continuously tumbles and mixes the herbal extracts within the inner tank, accelerating water evaporation and concentration of active ingredients. This ensures consistent concentration processes across different parts of the extract, fundamentally improving the stability of the active ingredient content in the finished traditional Chinese medicine and enhancing the overall product quality.
