Description

Technical Field

[0001] The utility model relates to the technical field of component extraction, in particular to a plant polyphenol extraction reflux device. Background Art

[0002] The compounds contained in plants are complex and numerous, and the number of types is beyond imagination. The content of different compounds also varies greatly, and different plant compound groups also vary greatly. In general, they are generally divided into primary metabolites, such as proteins, amino acids, etc.; secondary metabolites, such as alkaloids, flavonoids, terpenes and plant polyphenols, etc. Plant polyphenols (Plantpolyphenol), also known as vegetable tannins (Vegetable tannin), have a polyphenol structure and are mainly found in the skin, roots, leaves and fruits of plants. The content in plants is second only to cellulose, hemicellulose and lignin. Although plant polyphenols are easily soluble in water at high temperatures, they will rise with water vapor.

The extraction tank below the filter membrane stores the extraction liquid. When the extraction liquid needs to be repeatedly refluxed for extraction, it is only necessary to open the solenoid valve on the reflux pipe through the controller, close the solenoid valve on the liquid collection pipe at the same time, and start the liquid pump.

Figure 3 It is an internal cross-sectional view of the cooling box of the utility model, including an extraction device 101, a liquid reflux group 102 and a gas reflux assembly 103, the gas reflux group including an air duct 104, a spiral tube 105 and a cooling group 106; the cooling group 106 includes a water storage cylinder 107 and a connecting pipe 108, the cooling group 106 also includes a support frame 109 and a connecting plate 110, the cooling group 106 also includes a cooling box 111, a partition 112, an electric door 113 and a refrigeration plate 114. The above-mentioned scheme solves the problem that when the existing extraction device extracts plant polyphenols, the plant polyphenols will be lost with the steam discharge, thereby affecting the extraction efficiency of the plant polyphenols. It can be understood that the above-mentioned scheme can be used in the scenario of plant polyphenol extraction.

[0021] According to this specific embodiment, the liquid reflux group 102 is arranged on one side of the extraction device 101. The extraction device 101 is used to extract plant polyphenols from plants. The liquid reflux group 102 is used to extract the extract in the extraction device 101 and lead it back to the extraction device 101 for re-extraction, so as to improve the extraction quality of plant polyphenols. Specifically, when it is necessary to repeatedly reflux and extract the extract, it is only necessary to open the solenoid valve on the reflux pipe through the controller, and at the same time close the solenoid valve on the liquid collection pipe, and start the liquid pump. The liquid pump can pump the extract back to the extraction tank above the filter membrane through the liquid collection pipe and the reflux pipe, and turn on the power of the electric heating tube to achieve the effect of repeated reflux extraction of the extract, thereby reducing the labor intensity of the staff to a certain extent.

[0022] The air guide tube 104 is connected to the extraction device 101 and is located on one side of the extraction device 101. The spiral tube 105 is connected to the air guide tube 104 and the extraction device 101 and is located between the extraction device 101 and the air guide tube 104. The cooling group 106 is arranged outside the spiral tube 105. The gas reflux component 103 is used to guide the steam in the extraction device 101 and condense it back to the extraction device 101, thereby avoiding the phenomenon that the plant polyphenols are lost together with the steam. The steam generated by the extraction device 101 when heating and extracting the plant polyphenols is introduced into the spiral tube 105 through the air guide tube 104, and the cooling group 106 introduces a coolant to the outside of the spiral tube 105 in real time to wrap the spiral tube 105, thereby condensing the steam in the spiral tube 105, and the cooled extract is then introduced back into the extraction device 101 through the spiral tube 105 for extraction, thereby solving the problem that when the existing extraction device extracts the plant polyphenols, the plant polyphenols are lost along with the steam discharge, thereby affecting the extraction efficiency of the plant polyphenols.

[0023] Secondly, the water cylinder 107 is arranged on one side of the spiral tube 105, and the connecting pipe 108 is connected to the water cylinder 107 and is located on one side of the water cylinder 107. The water cylinder 107 is used to store coolant and condense the steam in the spiral tube 105. The connecting pipe 108 has two pipes, one for introducing coolant into the water cylinder 107, and the other for draining the coolant to realize the circulation of the coolant and avoid long-term use of the coolant to reduce the condensation effect of the steam in the spiral tube 105.

[0024] At the same time, the support frame 109 is fixedly connected to the water storage cylinder 107 and is located at the bottom of the water storage cylinder 107.

The refrigeration plate 114 is arranged on one side of the cooling box 111. The cooling liquid for condensing steam is stored in the cooling box 111 and is introduced into the connecting pipe 108 through a water pump, and then introduced into the water storage cylinder 107. The partition 112 forms a cooling chamber. The cooling box 111 is divided into a cooling bin and a storage bin. One side of the cooling bin is connected to the refrigeration fin 114. The heat absorbing end of the refrigeration fin 114 is arranged in the cooling box 111, and the heat releasing end is arranged outside the cooling box 111, and is used to cool the coolant guided back from the cooling bin. When the preset temperature sensor detects that the coolant reaches a preset value, the electric door 113 opens to guide the coolant in the cooling bin into the storage bin for use by the water storage cylinder 107. The electric door 113 includes a baffle and a telescopic rod. The opening and closing of the baffle is realized by the action of the telescopic rod.

[0026] When the gas reflux component 103 is in use, the steam is introduced into the spiral tube 105 through the air duct 104, and the connecting tube 108 introduces the coolant in the storage bin of the cooling box 111 into the water cylinder 107. The steam in the spiral tube 105 is condensed by the water cylinder 107, and the condensed extract is then guided back to the extraction device 101 through the spiral tube 105 for extraction. The coolant in the water cylinder 107 is circulated through the two connecting tubes 108, one for introducing the coolant into the water cylinder 107, and the other for guiding the coolant. The coolant is guided back to the cooling bin of the cooling box 111 for refrigeration. When the preset temperature sensor detects that the coolant reaches the preset value, the electric door 113 opens to guide the coolant in the cooling bin into the storage bin for use by the water cylinder 107.
