Description

Technical Field

[0001] The invention relates to the technical field of bioengineering, and in particular to a device and a method for extracting orange peel essential oil by using a microbial fermentation method. Background Art

[0002] Before extracting essential oil from orange peel, enzymatic hydrolysis is used to destroy the cell wall to release the essential oil in the cell, thereby improving the extraction rate of the essential oil. For example, cellulase enzymatic hydrolysis is used to assist in extracting orange peel essential oil. However, this method requires pure enzyme and a high amount of enzyme is used, which increases the production cost. Based on this, after searching, it was found that the Chinese invention patent with authorization announcement number CN111500371B discloses a method for extracting orange peel essential oil using a microbial fermentation method. The method ferments orange peel to obtain orange peel fermentation product, and then extracts the orange peel fermentation product by steam distillation to obtain orange peel essential oil. The extraction rate of orange peel essential oil can be improved by fermentation. However, it ignores the improvement of the steam distillation method. In the existing steam distillation method, the material (referring to orange peel) is generally placed in a distillation tank, and water vapor is passed from bottom to top. On the one hand, there will be gaps between the materials, and water vapor can easily pass through the gaps instead of passing through the materials. In this way, the efficiency of the essential oil components carried away by the steam flow is relatively low, which needs to be improved. On the other hand, in the existing distillation technology, after the distillation is completed, the material is generally cleaned up, and new material is put in for the next round of distillation. The whole process requires manual participation, and it is difficult to achieve automated operation. The efficiency is low, which needs to be improved.

[0003] Based on the above, the present invention proposes a device and method for extracting orange peel essential oil using a microbial fermentation method, which can improve the essential oil extraction effect and efficiency and realize automated operation. Summary of the invention

Initially, the upper and lower surfaces of the outer airbag are respectively close to the upper and lower sides of the inner surface of the lower conveyor belt, and the lower side of the outer surface of the lower conveyor belt is close to the fixing seat.

[0013] A slot is provided at the bottom of the fixed plate, a blocking plate is installed in the slot, the blocking plate includes a vertical plate inserted in the slot, the bottom of the vertical plate extends out of the slot and is installed with a horizontal plate, and the horizontal plate is connected to a linear module set on the outer surface of the distillation box.

[0014] As a further improvement and optimization of the present invention, a plurality of air holes are arrayed along the width direction of the lower conveyor belt to form an air hole column, a plurality of air hole columns are arrayed along the length direction of the lower conveyor belt, and a rubber layer is provided on the bottom of the horizontal plate of the sealing plate and the upper surface of the fixed seat.

[0015] As a further improvement and optimization of the present invention, the feeding component includes a feeding conveyor belt, the discharge end of the feeding conveyor belt is located above the feeding end of the lower conveyor belt, and a convex plate extends vertically on the outer surface of the feeding conveyor belt, and a plurality of convex plates are arranged in an array along the extension direction of the feeding conveyor belt.

[0017] As a further improvement and optimization of the present invention, during the distillation extraction of orange peel raw materials, the lower conveyor belt and the upper conveyor belt periodically move at the same speed and in the same direction, and the distance of each movement is equal to the distance between two adjacent air holes along the conveying direction of the lower conveyor belt.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This solution can realize the automated and continuous distillation extraction of orange peel raw materials. On this basis:

[0022] 1. Several air holes are arranged in array along the width direction of the lower conveyor belt to form an air hole column, and several air hole columns are arranged in array along the length direction of the lower conveyor belt. In this way, there will be a line between two adjacent air hole columns. Since the lower conveyor belt is generally made of rubber material, this line is equivalent to a sealing strip, that is, there are several clamped sealing strips between the blocking plate and the outer air bag and between the outer air bag and the fixing seat, so the sealing effect is better;

[0023] 2. Load the orange peel material into a cloth bag with good air permeability, and then place the cloth bag on the feed conveyor belt through the robotic arm technology. The thickness of the cloth bag on the feed conveyor belt is h2, and the distance between the upper and lower conveyor belts is h1, which is smaller than h2. Therefore, after the orange peel material enters the distillation box, the orange peel material will be pressed between the lower conveyor belt and the upper conveyor belt;

[0024] On the one hand, after being squeezed, the orange peel material will be compacted, greatly reducing the internal voids, so that the steam can pass through the orange peel instead of the voids, thus greatly improving the efficiency of distillation extraction;

[0025] On the other hand, after the distillation extraction has been performed for a preset time, the lower conveyor belt and the upper conveyor belt move at the same speed and in the same direction. The materials of the two are the same. Therefore, the forces on the upper and lower sides of the cloth between the lower conveyor belt and the upper conveyor belt are the same in magnitude and opposite in direction, which cancel each other out. Therefore, the cloth bag is stationary, and the movement distance of the lower conveyor belt and the upper conveyor belt is equal to the dimension of the sealing strip along the conveying direction of the lower conveyor belt. In this way, the orange peel material that was previously in contact with the sealing strip will be exposed to receive steam distillation. After the preset time, the lower conveyor belt and the upper conveyor belt move at the same speed and in the same direction again. This is repeated, so that the contact position of the orange peel material with the sealing strip is constantly changed, thereby improving the distillation extraction effect.

[0026] It should be noted that, since h1 is smaller than h2, not only will the orange peel raw material be pressed between the lower conveyor belt and the upper conveyor belt, but the lower conveyor belt and the upper conveyor belt will also undergo elastic deformation, which will tighten the lower conveyor belt and the upper conveyor belt, that is, the friction between the conveyor belts and the rotating roller of the lower conveyor belt and the upper conveyor belt will increase, so that when the rotating roller rotates to drive the conveyor belt to move, the conveyor belt moves more accurately, and the distribution of the air holes is relatively dense, that is, the sealing strip is thinner. Therefore, the movement of the lower conveyor belt and the upper conveyor belt needs to be more precise in order to achieve the above-mentioned continuous change of the contact position between the orange peel raw material and the sealing strip, thereby improving the distillation extraction effect.

DETAILED DESCRIPTION

[0036] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0037] In this scheme, a refers to a cloth bag loaded with fermented orange peels, and the cloth bag is made of cloth with good air permeability, such as linen, ramie cloth, etc., and steam can pass through the cloth bag smoothly, that is, the cloth bag will not block the steam and affect the distillation extraction process.

[0038] This scheme is to distill and extract orange peel that has been fermented by microorganisms to obtain orange peel essential oil. The orange peel mentioned in the following text refers to the orange peel that has been fermented by microorganisms.

[0039] Reference Figure 1-Figure 7 A device for extracting orange peel essential oil by microbial fermentation method includes a frame, on which a feeding component 100, a distillation box 200 and a condensation component 300 are installed, wherein the feeding component 100 is used to pull the orange peel into the distillation box 200 and evenly distribute the orange peel in the distillation box 200, and the distillation box 200 is used to realize the distillation extraction of essential oil components from the orange peel, and the extracted essential oil components flow into the condensation component 300 together with water vapor to condense to obtain essential oil.

[0040] Distillation box 200:

[0041] Reference Figure 1 and Figure 3-Figure 5A box cover 201 is installed at the upper box opening of the distillation box 200, a slag discharge port 203 and a water outlet 212 are arranged at the lower box bottom, a feed port 202 and a steam inlet 211 are arranged on the side of the distillation box 200 along the length direction, and a water guide plate 209 and a slag guide plate 210 arranged obliquely are also arranged in the distillation box 200, the distance between the water guide plate 209 and the slag guide plate 210 decreases from bottom to top and the highest points of the two are connected.

[0042] The slag discharge port 203 and the water outlet 212 are respectively located on the opposite sides of the water guide plate 209 and the slag guide plate 210. The slag discharge port 203 is close to the slag guide plate 210, and the water outlet 212 is close to the water guide plate 209. In addition, a sealing component 2 is provided at the slag discharge port 203. Furthermore, the sealing component 2 includes a gate plate 208 located below the slag discharge port 203 and a linear module 207 for driving the gate plate 208 to move. The upper surface of the gate plate 208 is in contact with the lower surface of the distillation box 200. The gate plate 208 is driven to move by the linear module 207, so that the slag discharge port 203 can be opened or closed.

[0043] A lower conveyor belt 204 and an upper conveyor belt 205 are installed in the distillation box 200, and the conveying direction is parallel to the length direction of the distillation box 200. The latter is located above the former, and a plurality of air holes are distributed in an array on the surfaces of both. Among them, the upper conveyor belt 205 is located in its entirety in the distillation box 200, and the discharge end of the lower conveyor belt 204 is located above the slag guide plate 210, and the feed end passes through the feed port 202 and is used to receive orange peels.

[0044] A plugging assembly 206 is installed at the feed inlet 202 for opening or closing the feed inlet 202. Figure 4 The blocking component 206 includes a fixing seat 2064 vertically arranged on the lower hole wall of the feed port 202 , an airbag component located in the lower conveyor belt 204 , and a fixing plate 2061 vertically arranged on the upper hole wall of the feed port 202 .

[0045] The airbag component includes an inner skeleton 2065 connected to the inner wall of the distillation box 200 and an outer airbag 2066 installed outside the inner skeleton 2065. An air nozzle extends from the outer surface of the outer airbag 2066. The end of the air nozzle extends out of the distillation box 200 and is technically connected to an air pump or an air compressor. Initially, the upper and lower surfaces of the outer airbag 2066 are respectively close to the upper and lower sides of the inner surface of the lower conveyor belt 204, and the lower side of the outer surface of the lower conveyor belt 204 is close to the fixed seat 2064.

[0046] A slot is provided at the bottom of the fixed plate 2061, and a sealing plate 2062 is installed in the slot. The sealing plate 2062 includes a vertical plate inserted in the slot. The bottom of the vertical plate extends out of the slot and is installed with a horizontal plate. The horizontal plate is connected to a linear module 2063 provided on the outer surface of the distillation box 200, and the sealing plate 2062 is driven to move in the vertical direction through the linear module 2063.

[0047] The working process of the blocking component 206 is as follows: initially, the blocking plate 2062 is driven upward by the linear module 2063 to open the feed port 202, and the lower conveyor belt 204 can pull the orange peel into the distillation box 200. After entering, air is injected into the outer air bag 2066 by the air compressor to make it collide and contact with the upper and lower sides of the inner surface of the lower conveyor belt 204. At the same time, the blocking plate 2062 is driven downward by the linear module 2063. During the downward movement, the blocking plate 2062 The bottom of 62 will press down the lower conveyor belt 204, and with the cooperation of the sealing plate 2062 and the external air bag 2066, a sealing cooperation among the lower conveyor belt 204, the sealing plate 2062 and the external air bag 2066 will be achieved. At the same time, the downward movement of the sealing plate 2062 will be transmitted to the lower half of the lower conveyor belt 204 through the external air bag 2066, so that the external air bag 2066 and the fixed seat 2064 clamp the lower half of the lower conveyor belt 204 to achieve a sealing cooperation, thereby achieving the purpose of closing the feed port 202.

[0048] It should be noted that, refer to Figure 4 The distribution of the air holes of the lower conveyor belt 204 is as follows: a number of air holes are arranged in an array along the width direction of the lower conveyor belt 204 to form an air hole column, and a number of air hole columns are arranged in an array along the length direction of the lower conveyor belt 204. In this way, there will be a line between two adjacent air hole columns, and since the lower conveyor belt 204 is generally made of rubber material, this line is equivalent to a sealing strip, that is, there are a number of clamped sealing strips between the sealing plate 2062 and the outer air bag 2066 and between the outer air bag 2066 and the fixed seat 2064. Therefore, the sealing effect is better. Preferably, the horizontal plate bottom of the sealing plate 2062 and the upper surface of the fixed seat 2064 are provided with a rubber layer to further improve the sealing effect.

[0049] Feeding member 100:

[0050] Reference Figure 2 The feeding component 100 includes a feeding conveyor belt 101, the discharge end of the feeding conveyor belt 101 is located above the feeding end of the lower conveyor belt 204, and a convex plate 1011 extends vertically from the outer surface of the feeding conveyor belt 101. A plurality of convex plates 1011 are arranged in an array along the extension direction of the feeding conveyor belt 101.

[0051] The feeding member 100 further includes a hopper 102 mounted on a frame and located above the feeding conveyor belt 101 .

[0052] A method for using a device for extracting orange peel essential oil using a microbial fermentation method:

[0053] The distance between the lower conveyor belt 204 and the upper conveyor belt 205 is h1, and the thickness of the orange peel material conveyed to the lower conveyor belt 204 by the feed conveyor belt 101 is h2, and h1 is less than h2;

[0054] Step 1: The orange peel material is pulled by the feed conveyor belt 101 and falls onto the lower conveyor belt 204, and the orange peel material is pulled by the lower conveyor belt 204 into the distillation box 200;

[0055] Step 2: After the orange peel raw material is transported into the distillation box 200, the feed port 202 and the slag discharge port 203 are closed, and at the same time, steam enters the distillation box 200 through the steam inlet 211, and the essential oil of the orange peel raw material is extracted by steam. The extracted essential oil components and the steam enter the condensation component 300 through the connecting pipe 302 arranged between the box cover 201 and the condensation component 300;

[0056] Step 3: After the distillation and extraction of the orange peel raw material is completed, the feed port 202 and the slag discharge port 203 are opened, and the lower conveyor belt 204 and the upper conveyor belt 205 move at the same speed but in different directions, pulling the orange peel raw material to fall onto the slag guide plate 210, and finally discharged through the slag discharge port 203, while new orange peel raw material enters the distillation box 200, and this process is repeated to achieve automated and continuous essential oil distillation and extraction of the orange peel raw material.

[0057] In the above process:

[0058] The feeding member 100 has two feeding modes:

[0059] First, the orange peel material is directly put into the hopper 102. The bottom of the hopper 102 is close to the feeding conveyor belt 101. The two sides of the hopper 102 along the conveying direction of the feeding conveyor belt 101 are provided with avoidance openings for avoiding the convex plate 1011. The convex plate 1011 that moves with the feeding conveyor belt 101 pushes the orange peel material to move, and the orange peel material will eventually fall into the feeding end of the lower conveyor belt 204. In this process: on the one hand, the orange peel can be evenly distributed on the lower conveyor belt 204. On the other hand, the height of the convex plate 1011 is equivalent to h2. Since h1 is less than h2, after the orange peel material enters the distillation box 200, the orange peel material will be pressed between the lower conveyor belt 204 and the upper conveyor belt 205. After being squeezed, the orange peel material will be compacted, which greatly reduces the internal gaps. Therefore, the steam can pass through the orange peel instead of the gaps, so the efficiency of distillation extraction can be greatly improved.

[0060] Preferably, in the first mode, it is easy for orange peel raw materials to remain on the lower conveyor belt 204 and the upper conveyor belt 205, so refer to Figure 5 An air blowing pipe 213 is installed inside the lower conveyor belt 204 and the upper conveyor belt 205. The air blowing pipe 213 is parallel to the width direction of the lower conveyor belt 204. The air blowing pipe 213 is close to the discharge end of the lower conveyor belt 204 or the upper conveyor belt 205. A blowing hole 2131 is opened at the lowest point of the outer circular surface of the air blowing pipe 213. A blower is connected to the end of the air blowing pipe 213. The air flow provided by the blower is blown toward the lower conveyor belt 204 or the upper conveyor belt 205 through the blowing hole 2131 to blow off the orange peel material stuck on the lower conveyor belt 204 or the upper conveyor belt 205.

[0061] Secondly, the orange peel material is loaded into a cloth bag with good air permeability, and then the cloth bag is placed on the feed conveyor belt 101 through the robot arm technology. The thickness of the cloth bag on the feed conveyor belt 101 is equivalent to h2. Therefore, after the orange peel material enters the distillation box 200, the orange peel material will also be pressed between the lower conveyor belt 204 and the upper conveyor belt 205. In this process: on the one hand, it can also play a role in evenly distributing and reducing the gaps in the temporal part of the orange peel material, thereby improving the efficiency of distillation extraction. On the other hand, after the distillation extraction has been carried out for a preset time, the lower conveyor belt 204 and the upper conveyor belt 205 move at the same speed and in the same direction. The materials of the two are the same. Therefore, the lower conveyor belt 204 and the upper conveyor belt 205 are located between the lower conveyor belt 204 and the upper conveyor belt 205. The forces on the upper and lower sides of the cloth between the conveyor belts 205 are of the same magnitude and opposite directions, which cancel each other out. Therefore, the cloth bag is stationary, and the movement distance of the lower conveyor belt 204 and the upper conveyor belt 205 is equal to the dimension of the sealing strip along the conveying direction of the lower conveyor belt 204. In this way, the orange peel material previously in contact with the sealing strip will be exposed to be distilled by steam, so that all parts of the orange peel material are distilled by steam, thereby improving the distillation extraction effect. After a preset time, the lower conveyor belt 204 and the upper conveyor belt 205 move at the same speed and in the same direction again, and this is repeated, so that the contact position of the orange peel material with the sealing strip is constantly changed, thereby improving the distillation extraction effect.

[0062] In the second method, it should be noted that since h1 is smaller than h2, not only will the orange peel raw material be pressed between the lower conveyor belt 204 and the upper conveyor belt 205, but the lower conveyor belt 204 and the upper conveyor belt 205 will also undergo elastic deformation, which will tighten the lower conveyor belt 204 and the upper conveyor belt 205, that is, the friction between the conveyor belts and the rotating roller of the lower conveyor belt 204 and the upper conveyor belt 205 will increase, so that when the rotating roller rotates to drive the conveyor belt to move, the moving distance of the conveyor belt is more precise, and the distribution of the air holes is relatively dense, that is, the sealing strip is thinner, and therefore, the movement of the lower conveyor belt 204 and the upper conveyor belt 205 needs to be more precise.

[0063] Condensation member 300:

[0064] Reference Figure 6 and Figure 7 The condensation component 300 includes a condensation tank 301 , and a lower water inlet 3011 and an upper water outlet 3012 are provided on the outer surface of the condensation tank 301 . Through water pump technology, cold water is drawn into the condensation tank 301 from the lower water inlet 3011 and flows out from the upper water outlet 3012 .

[0065] A condenser 306 is installed in the condenser tank 301. The condenser 306 is in a continuously bent shape and has a plurality of fins 307 arranged in an array on the outer surface. A vertical pipe is extended from each of the upper and lower ends of the condenser 306. The vertical pipe is coaxial with the condenser tank 301 and the ends extend out of the condenser tank 301. The end of the vertical pipe at the bottom is connected to the output pipe 303 through a rotating joint. An exhaust pipe 304 extends vertically at the highest point of the outer cylindrical surface of the output pipe 303. The end of the vertical pipe at the top is connected to the connecting pipe 302 through a rotating joint. The end of the connecting pipe 302 is connected to the box cover 201. In addition, a motor 305 for driving the vertical pipe at the top to rotate is also provided on the frame.

[0066] The orange peel essential oil components flow into the condenser 306 together with the steam through the connecting pipe 302. In the condenser 306, after the heat exchange with the cold water, the essential oil components are condensed into liquid, and the essential oil is discharged from the output pipe 303, and the gas is discharged from the exhaust pipe 304. During the condensation process, the motor 305 drives the condenser 306 to rotate, and the cold water is stirred through the condenser 306 and the fins 307 to improve the condensation effect.

[0067] In this solution, the linear module can be the existing electric telescopic rod technology, or the existing screw linear motion technology, which will not be described in detail.
