[0010] This invention provides an integrated microwave vacuum countercurrent cell wall breaking extraction, concentration, and condensation recovery machine.

[0011] Compared with existing technologies, it has the following advantages:

[0012] 1.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 This utility model provides a technical solution: a microwave vacuum countercurrent cell breaking extraction and concentration, condensation and recovery integrated machine, including a raw material tank 1 and pipeline 3. The raw material tank 1 is provided with a feed inlet 4. The discharge end of the raw material tank 1 is sequentially provided with a metering pump 5, a thermometer 6, a first ball valve 7 and a finished product pump 8. A second ball valve 10 is provided between the thermometer 6 and the first ball valve 7. The end of the second ball valve 10 is connected to a material tank 11. An outer tank 9 is provided on the outside of the material tank 11. One side of the raw material tank 1 is connected to the material tank 11 through an overflow pipe. The overflow pipe and the outer tank 9 are connected through each other, so that the raw material inside the material tank 11 can overflow into the raw material tank 1 for circulation. The outer tank 9 is provided with a quick-installation mechanism 2. A microwave generator 12 is installed on the quick-installation mechanism 2. Multiple microwave generators 12 are evenly arranged around the material tank 11. The microwave generator 12 is detachably connected to the outer tank 9, allowing multiple microwave generators 12 to uniformly heat the raw materials inside the material barrel 11. The top of the outer tank 9 is connected to a condenser 13, and the outer tank 9 has a viewing window. The air outlet of the outer tank 9 is connected to the condenser 13, allowing observation of the internal condition of the outer tank 9 through the viewing window. One end of the condenser 13 is connected to a chiller 14, and the condenser 13 is also connected to a vacuum pump 18 and a condensate storage tank 16. The top of the raw material barrel 1 is connected to the condenser 13, and the condenser 13 is connected to the condensate storage tank 16, allowing the medium inside the condenser 13 to enter the raw material barrel 1 and the condensate storage tank 16. A third ball valve 17 is provided between the condensate storage tank 16 and the condenser 13, and a fourth ball valve 15 is provided between the raw material barrel 1 and the condenser 13.

[0020] Please see Figure 1-3The quick-installation mechanism 2 includes a mounting base 201. A fixing block 203 is fixedly connected to the bottom of the microwave generator 12. The mounting base 201 has an embedding groove 202. Guide seats 204 are fixedly connected to both sides inside the embedding groove 202. A sliding block 205 is provided inside the guide seat 204. A limit groove 206 is provided on the sliding block 205. A return spring 207 is provided on one side of the sliding block 205. The return spring 207 can reset the sliding block 205. The opposite ends of the sliding block 205 and the fixing block 203 have inclined surfaces, which can facilitate the fixing block 203 to push the sliding block 205 to move using the inclined surfaces, so as to facilitate direct insertion and locking. A U-shaped connecting rod 208 is fixedly connected between the two sliding blocks 205. The U-shaped connecting rod 208 passes through the mounting base 201 and extends to the outside of the mounting base 201. Pulling the U-shaped connecting rod 208 can move the sliding block 205, facilitating unlocking and removal. The sliding block 205 is slidably connected to the inner wall of the mounting base 201 through the limiting groove 206. By inserting the fixing block 203 into the embedding groove 202, the fixing block 203 uses its inclined surface to push the sliding block 205 to move. The movement of the sliding block 205 compresses the reset spring 207. After the fixing block 203 is fully inserted, the sliding block 205 separates from the inclined surface of the fixing block 203, and the reset spring 207 resets the sliding block 205, locking the fixing block 203 to complete the installation. This facilitates the installation and maintenance of the microwave generator 12.

[0021] During operation, the first ball valve 7 and the third ball valve 17 are closed. The prepared extract and solvent are mixed in a certain proportion to obtain the raw material, which is added through the feed port 4. After passing through the metering pump 5 and the second ball valve 10, the raw material enters the material tank 11. The liquid rises in a countercurrent manner and overflows back to the raw material tank 1 after being heated by microwave. The cycle is repeated. When the temperature reaches the set temperature, the vacuum pump 18 is started. The evaporated gas is condensed through the condenser 13. The condensation temperature is set by the chiller 14 according to the vacuum boiling point of the solvent. The condensate returns to the raw material tank 1 through the fourth ball valve 15 and mixes with the raw material. The amount of solvent remains unchanged and extraction continues.

[0022] By using vacuum pump 18 and chiller 14 to supply refrigerant to condenser 13, the negative pressure value can be controlled, thereby changing the boiling point temperature of the solvent. Depending on the characteristics of the material, the temperature can be adjusted from 5 degrees to 65 degrees, achieving low-temperature extraction and better retention of useful aromatic substances and other soluble components.

[0023] Microwave vacuum heating cell disruption technology uses high-intensity electromagnetic waves generated by microwave generator 12 in a vacuum state to rapidly heat the raw materials to the boiling point without the need for a medium, causing rapid vaporization and cell rupture, releasing useful substances. This process is several times faster than traditional distillation and extraction.

[0024] After the raw materials meet the extraction requirements, stop the vacuum pump 18, release the vacuum, open the first ball valve 7 and the finished product pump 8, and extract the extracted raw materials for later use.

[0025] Because extraction is performed under vacuum and low temperature and low oxygen conditions, it is very safe to use organic solvents and can be recycled.

[0026] Concentration and condensation recovery

[0027] After closing the fourth ball valve 15 and the first ball valve 7, the extracted stock solution is passed through a multi-stage filtration device of 50 mesh, 200 mesh, and 300 mesh for solid-liquid separation to obtain a low-concentration stock solution. The stock solution is added from the feed inlet 4, and the vacuum pump 18 is started to reach the set value. After passing through the metering pump 5 and the second ball valve 10, the liquid enters the material tank 11 and rises in the countercurrent. After being heated by microwave, it overflows into the raw material tank 1 and is circulated again. After the solvent reaches the boiling point, it enters the condenser 13 and condenses into liquid. It returns to the condensate storage tank 16 through the second ball valve 10. Before the concentration is reached, the above cycle is repeated through the metering pump 5.

[0028] The vacuum pump 18 is adjustable from atmospheric pressure to absolute pressure of 800 Pa, i.e., between 100 degrees and 5 degrees, which is suitable for the concentration requirements of most extracts.

[0029] The countercurrent circulation ensures that the original solution is rapidly heated and concentrated in a very uniform manner under the action of the microwave generator 12.

[0030] Once the required concentration is reached, open the first ball valve 7 and the finished product pump 8 to pump out the finished product for later use.

[0031] Microwaves have excellent low-temperature sterilization properties, which can extend the shelf life of concentrated products.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
