Description

Technical Field

[0001] The present invention belongs to the technical field of plant extract concentration, and more specifically, relates to a low-temperature concentration process and system for plant extract. Background Art

[0002] Concentration is a unit operation that removes part of the solvent from the solution. It is a partial separation process of a uniform mixture of solute and solvent. Freeze concentration is completed at low temperatures and has the characteristics of preventing adverse chemical and biochemical changes. At the same time, the loss of flavor, aroma and nutrition is small. It is particularly suitable for concentrating heat-sensitive liquid foods, biopharmaceuticals, high-end beverages and Chinese herbal decoctions that require the preservation of natural color, aroma and flavor. It can be used for the concentrated extraction of aromatic and non-aromatic plants, including Panax notoginseng, Erigeron breviscapus, rose, geranium, Polygonatum, mint, honeysuckle, dendrobium and flowers, Polygonatum sibiricum, clove, lavender, chrysanthemum, turmeric, Chuanxiong, Chinese angelica, Angelica dahurica, Atractylodes macrocephala, ginseng and flowers, Fritillaria cirrhosa, chrysanthemum, etc. Existing low-temperature concentration of plant extracts has the following problems when used:

[0003] The application number (202211098604.5) discloses a low-temperature concentration process and system for rose extract. The system utilizes five storage chambers, four purification chambers, a liquid inlet pipe, and a liquid outlet pipe. With the cooperation of a telescopic drive assembly and a piston plate, the system enables alternating circulation of the rose extract between the storage chambers and the purification chambers. The system uses a multi-port refrigeration assembly to cool the inclined heat exchange grooves within the four purification chambers, allowing the rose extract to continuously exchange heat with the inclined heat exchange grooves until the temperature gradually reaches the condensation point, causing the water in the rose extract to freeze and precipitate. This system achieves streamlined purification of the rose extract. The system is easy to operate, simple in structure, and very convenient to use. It effectively avoids damage to the active ingredients in the rose extract and allows direct storage without the need for static cooling.

[0020] A low-temperature concentration process for plant extracts, comprising the following steps:

[0021] S1: When in use, the plant extract to be concentrated is injected into one end of the mounting frame. After the plant extract enters the mounting frame, it pushes the valve disc to one side, thereby pushing the valve disc open and entering the movable frame. The movable frame can slide inside the movable frame through the guide rail through the slide groove. The position of the movable frame can be fixed by the card block. The extract passing through the movable frame can be filtered by the filter screen inside the movable frame, and the filtered impurities are retained inside the movable frame. The filtered plant extract enters the concentration tank through the feed pipe;

[0022] S2: The liquid inside the concentration tank is heated by the heating wire, and the air pump can absorb the gas inside the interlayer through the connecting pipe, so that the air inside the concentration tank enters the cavity through the internal vent hole of the mounting part, thereby lowering the boiling point of the liquid inside the concentration tank and causing the water inside the extract to boil and evaporate into water vapor;

[0023] S3: By installing the fixed plate inside the partition and opening a flow cavity inside the fixed plate, the water vapor formed inside the concentration tank when the air pump extracts gas can enter the partition through the air inlet hole and be discharged together through the connecting pipe.

After the extraction is completed, the concentrated liquid is discharged through the discharge pipe by opening the solenoid valve.

[0024] The technical effects achieved by the present invention are:

[0025] (1) This scheme sets up a high-efficiency concentration mechanism. When the plant extract enters the concentration tank, the liquid inside the concentration tank is heated by setting a heating wire. The liquid inside the concentration tank can be stirred during the rotation of the installation shaft by setting a mounting part, so that the liquid inside the concentration tank is heated more evenly and the liquid inside the concentration tank can be heated stably. The air pump can absorb the gas inside the interlayer through the connecting pipe, so that the air inside the concentration tank enters the cavity through the internal vent hole of the mounting part, thereby reducing the boiling point of the liquid inside the concentration tank and making the concentration efficiency of the concentration device higher.

[0026] (2) A filtering mechanism is provided. The position of the movable frame can be fixed by setting a card block. The extract passing through the movable frame can be filtered by setting a filter screen inside the movable frame. Impurities in the plant extract can be filtered to improve the quality of the concentrated liquid and the filtered impurities can be retained inside the movable frame. After the movable frame is taken out, the movable frame is pushed to one side so that the movable frame is located on the side of the card block. The second tension spring will quickly pull the movable frame back, thereby shaking off most of the impurities attached to the filter screen, making it easier to clean the filter screen. The valve disc can be blocked by setting a blocking plate so that the valve disc can only move to one side, thereby preventing the filter inside the movable frame from flowing back. The movable plate can be used to facilitate the removal of the filter inside the movable frame, making it easier to collect and process the filtered impurities.

[0027] (3) A collection mechanism is provided. By installing a fixed plate inside the partition and opening a flow cavity inside the fixed plate, water vapor formed inside the concentration tank body when the air pump extracts gas can enter the partition through the air inlet hole and be discharged together through the inside of the connecting pipe. By providing an arc-shaped baffle and opening a through hole inside the baffle, the water vapor condensed inside the flow cavity can be reduced from flowing into the concentration tank body, thereby improving the concentration efficiency of the concentration device;

[0028] (4) A condensation mechanism is provided. When water vapor enters the condensation cylinder through the connecting pipe, it adheres to the side wall of the fixing part and the condensation hole inside. The air pumped out by the air pump can quickly cool the water vapor and condense it into water inside the condensation cylinder. By providing a water pump and a connecting pipe, the water condensed inside the condensation cylinder can be injected into the water storage tank for storage.

[0029] (5) By setting a temperature sensing device, the temperature of the liquid inside the concentration tank can be sensed, and by setting a number of mounting rods, the temperature of the liquid at different positions can be sensed, so that the heating temperature of the heating wire on the side wall of different mounting rods can be adjusted, making the concentration device more applicable.

[0052] The working process and principle of the present invention are as follows: when in use, the plant extract to be concentrated is injected into one end of the mounting frame 301.

The filtered plant extract enters the concentration tank 1 through the feed pipe 3, and is heated by setting the heating wire 110. The liquid inside the concentration tank body 1 is heated. The temperature of the liquid inside the concentration tank body 1 can be sensed by setting a temperature sensing device 111.

The temperature of the heating wire 110 can also be adjusted according to different plant extracts. The servo motor 101 can drive the mounting shaft 102 to rotate slowly inside the concentration tank body 1. The mounting member 105 can be used to stir the liquid inside the concentration tank body 1 during the rotation of the mounting shaft 102, so that the liquid inside the concentration tank body 1 is heated more evenly. The fixed guide member 106 can be used to stir the liquid. The effect is better. By setting the baffle 112, the rotation of the bottom liquid can be blocked during the stirring process of the mounting member 105, thereby reducing the vortex of the liquid inside the concentration tank body 1, so that the liquid inside the concentration tank body 1 can be stably heated. The air pump 1011 can absorb the gas inside the interlayer through the connecting pipe 104, so that the air inside the concentration tank body 1 enters the cavity 113 through the internal vent hole 107 of the mounting member 105, thereby reducing the boiling point of the liquid inside the concentration tank body 1 and making the concentration efficiency of the concentration device higher. By installing the fixing plate 2 inside the partition 103 and opening a flow cavity 202 inside the fixing plate 2, the water vapor formed inside the concentration tank body 1 when the air pump 1011 extracts gas can enter the partition through the air inlet 201 The water in the layer is discharged together through the inside of the connecting pipe 104. By setting an arc-shaped baffle 203 and opening a through hole 204 inside the baffle 203, the water vapor condensed inside the circulation cavity 202 can be reduced from flowing into the interior of the concentration tank 1, thereby improving the concentration efficiency of the concentration device. When the water vapor enters the condensation cylinder 4 through the connecting pipe 104, it will adhere to the side wall of the fixing part 401 and the internal condensation hole 402. The air drawn out by the air pump 1011 can quickly cool the water vapor and condense it into water inside the condensation cylinder 4. By setting a water pump and a connecting pipe 404, the water condensed inside the condensation cylinder 4 can be injected into the water storage tank 406 for storage. After the extraction is completed, the solenoid valve 501 is opened to discharge the concentrated liquid through the discharge pipe 5.
