[0014] The following further describes the present utility model in conjunction with all the drawings. The preferred embodiment of the present utility model is as follows. Refer to the attached Figure 1 to attached Figure 2The fresh bamboo sap extraction device described in this embodiment includes an extraction box 1. A water storage tank 2 is provided on the ground outside the extraction box 1. The water outlet pipe of the water storage tank 2 is connected to an evaporator 13. An auxiliary material pipe 14 is provided on the evaporator 13, and the outlet of the auxiliary material pipe 14 is connected to the inner cavity of the extraction box 1. A negative pressure pump 8 is provided on the ground on one side of the water storage tank 2. A negative pressure pipe 9 is connected to the negative pressure pump 8, and the outlet of the negative pressure pipe 9 is connected to the inner cavity of the extraction box 1. Fans 3 are installed on both side walls of the inner cavity of the extraction box 1. A heating tube 4 is installed on the outside of the air outlet of the fan 3. A drain port 6 is provided at one bottom end of the extraction box 1, and the drain port 6 is connected to an external collection pipe 7. A condenser pipe 10 is provided at the bottom of the inner cavity of the extraction box 1. A condenser 11 is provided on the ground on the other side of the water storage tank 2, and the condenser 11 is connected to the condenser pipe 10.

[0015] The evaporator 13 includes a shell 15 and a heater 16. The inner cavity of the shell 15 is divided into an upper evaporation chamber and a lower heating chamber by a partition 17. The heater 16 is installed at the bottom of the partition 17 in 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. The top of the shell 15 is connected to the auxiliary material pipe 14.

[0016] The surface of the heating element 4 is covered with heat-conducting fins 12 arranged in a ring or spiral pattern. A guide rail is provided at the bottom of the extraction chamber 1, and the condenser tubes 10 are installed in a U-shape or a snake-like pattern inside the extraction chamber 1 on both sides of the guide rail. Each side has two rows of fans 3 installed inside the extraction chamber 1 from top to bottom, with more than three fans in each row. Side plates 5 are installed at the top and bottom of the fans 3, and the thickness of the side plates 5 is greater than the thickness of the fans 3. The heating element 4 is installed in a U-shape or a snake-like pattern between the two side plates 5.

[0017] After adopting the above scheme, a door is opened at one end of the extraction box in the conventional manner (for 1-2 year old bamboo). The cut bamboo slices are placed on the outer shelf, and the shelf is pushed into the extraction box through the guide rail. The door is closed, the negative pressure pump is turned on, and the air in the extraction box is extracted through the negative pressure pipe to create a negative pressure inside the box. The negative pressure pump is turned off, and the heating element is turned on to generate heat. The heating element has heat-conducting plates distributed in a ring or spiral shape, which can quickly conduct and dissipate the heat. The fan is turned on to blow away the heat on the heating element and the heat-conducting plates to create convection, so that the temperature inside the box is high. The high temperature evaporates the moisture in the bamboo slices to form atomized fresh bamboo sap.

[0018] (i) When fresh bamboo sap is being supplied normally, the condenser is turned on while atomizing, and the atomized fresh bamboo sap is condensed through the condenser tube to liquefy the atomized fresh bamboo sap. The liquefied fresh bamboo sap water is discharged through the drain outlet and collected uniformly.

[0019] (II) When extracting fresh bamboo juice with special requirements, the auxiliary materials are put into the auxiliary material box while the bamboo pieces are heated, and 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 to evaporate and atomize the water in the evaporation chamber. The water mist rises through the auxiliary material box while dissolving and combining with 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 juice (forms a water molecule mixture, so it cannot be additionally blended). After mixing, the condensed pipe is used for condensation, and finally the fresh bamboo juice containing auxiliary materials is formed. This method is suitable for industries (such as health products and beverages) that have special requirements for fresh bamboo juice.

[0020] (III) When extracting high-purity fresh bamboo juice, the water in the bamboo pieces is evaporated by high temperature to form atomized fresh bamboo juice while the bamboo pieces are heated. After a certain period of delay, the condenser is opened, and the atomized fresh bamboo juice is condensed through the condensing pipe to liquefy the atomized fresh bamboo juice. In this way, the fresh bamboo juice can be purified, the water content of the fresh bamboo juice is lower, the effective components are higher, and the liquefied fresh bamboo juice is discharged through the liquid outlet for unified collection. This method is suitable for industries (such as pharmaceutical products) that require fresh bamboo juice concentration. The structure after using this scheme is reasonable, the evaporation extraction effect is good, and the efficiency is high.

[0021] (IV) When extracting bamboo that is more than 2 years old, the water content in the bamboo is very low, so the water is injected into the evaporation chamber through the water outlet pipe of the water storage tank, the heater heats to evaporate and atomize the water in the evaporation chamber, the water mist rises through the auxiliary material box (no auxiliary materials or auxiliary materials can be added), and the auxiliary material pipe enters the extraction box to contact the bamboo pieces. The fan blows, the heating tube is heated, the temperature in the control box is controlled at 60-80℃, the water mist fully contacts the bamboo pieces and enters the bamboo pieces, and the temperature is kept constant for 1-3 hours. Then, under negative pressure, the water in the bamboo pieces is evaporated again at high temperature.

[0022] The above embodiments are only preferred embodiments of the present application, and do not limit the scope of the application. Any changes made according to the shape and principle of the present application should be covered within the scope of protection of the present application.
