AI Technical Summary
Among the existing fresh bamboo juice extraction methods, the high water content and active ingredient content caused by the steaming method are relatively low, and the process of using organic solvents is complex and poses safety risks.
A fresh bamboo leach circulating extraction system is designed. By forming a negative pressure in the extraction box, the water in the bamboo sheet is evaporated by high-temperature evaporation, and the atomized fresh bamboo leach is liquefied through a condenser. Then, through the process of circulating evaporation and condensation, the water content of the fresh bamboo leach is gradually reduced and the content of the active ingredients is increased.
The cyclic extraction of fresh bamboo leach with reasonable structure, good evaporation and extraction effect and high efficiency is achieved, which reduces the water content of fresh bamboo leach, increases the content of active ingredients, and avoids the safety hazards of using organic solvents.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of traditional Chinese medicine extraction, in particular to a fresh bamboo sap circulation extraction system. Background Art
[0002] Fresh bamboo juice is a light yellow to reddish brown liquid that is drained from bamboo after heating. It has a bamboo aroma and a slightly sweet taste. "Ben Jing" says that bamboo juice is used to treat wind spasm; "Ben Cao Bei Yao" says that it can eliminate wind and reduce fire, moisten dryness and remove phlegm, nourish blood and benefit yin, improve eyesight, and treat aphrodisiac, phlegm and fever, wind spasm and madness, boredom and thirst, and spontaneous sweating due to blood deficiency; therefore, fresh bamboo juice has the effects of clearing heat and resolving phlegm, calming the nerves and improving the orifices, and is used to treat severe infection, lung heat and expectoration, asthma and chest tightness, strong tongue due to stroke, phlegm and saliva congestion, and phlegm-heat convulsions in children. Fresh bamboo juice contains sugar, amino acids, phenols and other ingredients. In addition to being the main energy source for cell life activities, sugars also have obvious immune-promoting effects. At present, there are several main methods for preparing fresh bamboo juice: 1. Extract fresh bamboo juice by steaming: cut fresh bamboo, break it with a hammer, soak it in water, heat it and boil it, and filter it to obtain fresh bamboo juice. The fresh bamboo sap obtained in this way has too much water content and low content of effective ingredients; 2. Add some ethanol and other organic solvents to soak, boil, and recover the organic solvents to produce fresh bamboo sap. For example, methyl, propyl, and butyl alcohols are very toxic, and methanol causes liver cirrhosis, etc., and the process is complicated. Summary of the invention

[0013] The evaporator 13 includes a shell 15 and a heater 16, wherein the middle of the inner cavity of the shell 15 is divided by a partition 17 to form an upper evaporation chamber and a lower heating chamber. The heater 16 is installed at the bottom of the partition 17 of the heating chamber. The water outlet pipe of the water storage tank 2 is connected to the middle of the evaporation chamber. An auxiliary material box 18 is installed on the upper part of the heating chamber. The auxiliary material box 18 is made of a mesh plate, and the top of the shell 15 is connected to the auxiliary material pipe 14.
[0014] The surface of the heating tube 4 is provided with heat conducting sheets 12 in an annular or spiral shape. A guide rail is provided at the bottom of the inner cavity of the extraction box 1, and the condensing tube 10 is installed in the extraction box 1 on both sides of the guide rail in a "U" shape or a "snake" shape. The fans 3 on each side are installed in the extraction box 1 in two rows from top to bottom, and the number of fans 3 in each row is greater than 3.
[0015] After adopting the above scheme, a box door is opened at one end of the extraction box in a conventional manner, (1-2 year old bamboo) the cut bamboo pieces are placed on the external shelf, the shelf is pushed into the extraction box through the guide rail, the box door is closed, the negative pressure pump is turned on, the air in the extraction box is extracted through the negative pressure pipe, so that negative pressure is formed in the box, the negative pressure pump is turned off, the heating pipe is turned on for heating, the heat of the heating pipe can be quickly conducted and dissipated by using the heat conducting sheet distributed in an annular or spiral shape, the fan is turned on to blow the heat on the heating pipe and the heat conducting sheet to form convection, so that high temperature is formed in the box; the moisture in the bamboo pieces is evaporated by the high temperature to form atomized fresh bamboo juice; (i) When fresh bamboo juice is normally provided, the condenser is opened while atomizing, and the atomized fresh bamboo juice is condensed through the condenser tube to liquefy the atomized fresh bamboo juice, and the liquefied fresh bamboo juice is discharged through the drain port for unified collection; (ii) When extracting fresh bamboo sap with special requirements, while heating the bamboo slices, the auxiliary materials are bagged as needed and placed in an auxiliary material box. The water outlet pipe of the water storage tank injects water into the evaporation chamber (the liquid auxiliary materials can also be directly poured into the evaporation chamber for direct evaporation). The heater heats the water in the evaporation chamber to evaporate and atomize. The water mist rises and passes through the auxiliary material box while dissolving and combining the auxiliary materials to form auxiliary material water vapor. The auxiliary material water vapor enters the extraction box through the auxiliary material pipe and mixes with the atomized fresh bamboo sap (forming a mixture of water molecules, so that it cannot be blended separately). After mixing, it is condensed through a condenser tube to finally form fresh bamboo sap containing auxiliary materials. The fresh bamboo sap prepared by this method is suitable for industries with special requirements for fresh bamboo sap (such as health products, beverages, etc.); (III) When extracting high-purity fresh bamboo sap, while heating the bamboo slices, the water in the bamboo slices is evaporated by high temperature to form atomized fresh bamboo sap; after a delay of a period of time, the condenser is opened, and the atomized fresh bamboo sap is condensed through the condenser tube to liquefy the atomized fresh bamboo sap. In this way, the fresh bamboo sap can be purified to make the water content of the fresh bamboo sap lower and the effective ingredients higher. The liquefied fresh bamboo sap is discharged through the drain port and collected uniformly. The fresh bamboo sap prepared by this method is suitable for industries that have requirements for the concentration of fresh bamboo sap (such as pharmaceuticals); the structure after adopting this scheme is reasonable, the evaporation extraction effect is good, and the efficiency is high.
[0016] (IV) When extracting bamboo that is more than 2 years old, since the water content in the bamboo itself is very low, water is first injected into the evaporation chamber through the outlet pipe of the water storage tank. The heater heats the water in the evaporation chamber to evaporate and atomize. The water mist rises and passes through the auxiliary material box (with or without auxiliary materials) and enters the extraction box through the auxiliary material pipe to contact the bamboo chips. The fan is used to blow air, and the heating tube is turned on to generate heat. The temperature in the box is controlled at 60-80℃, so that the water mist is fully in contact with the bamboo chips and enters the bamboo chips. The constant temperature is maintained for 1-3 hours, and then negative pressure is applied to evaporate the water in the bamboo chips again at high temperature.
[0017] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all changes made according to the shape and principle of the present invention should be included in the protection scope of the present invention.
