Problems solved by technology

However, CO 2 It is necessary to extract and process hop extract under the ultra-high pressure state above 20MPa, the price of the produced product is relatively expensive, and it is impossible to extract and separate hop extract and hop essential oil at the same time on a set of equipment, so this method is very important in hop production. It is restricted to a certain extent in the large-scale application of

Embodiment 1

[0037] Embodiment 1: 406A fluid extraction separates hop extract and hop essential oil, comprises the following steps:

[0038](1) Dried and crushed the hop raw material, granulated according to the diameter of Φ3mm-Φ6mm, and put it into the extraction kettle. When the volume of the raw material reached 1 / 2 of the volume of the extraction kettle, stop feeding and close the feeding and discharging control butterfly valve.

[0039] (2) The vacuum pump reduces the vacuum of the extraction kettle to 1×10 4 Below pa, remove the non-condensable gas in the kettle.

[0040] (3) Pour the liquid 406A in the solvent storage tank into the extraction kettle until the hop raw material is completely submerged, heat the extraction kettle to raise the temperature to 40°C-45°C, and the extraction pressure to 0.8MPa-1.3MPa, stir and mix the raw materials and solvent, soak and extract For 50 minutes, filter and separate the solid-liquid phase; repeat the extraction three to four times, and injec...

Embodiment 2

[0044] Example 2: Separation of hop extract and hop essential oil by hydrofluorocarbon 134A fluid extraction

[0045] The steps included in this embodiment are all the same as those in Embodiment 1.

Embodiment 3

[0046] Example 3: Extraction and separation of hop extract and hop essential oil by 406A fluid and its ethanol mixed solution

[0047] Steps (1) and (2) of this embodiment are the same as those of Embodiment 1.

[0048] (3) The liquid 406A in the solvent storage tank is injected into the extraction kettle until the hop raw material is fully submerged, then the 95% ethanol solution in the entrainer tank is injected into the extraction kettle to change the polarity of the mixed solvent, and the volume ratio of 406A and ethanol is controlled to be about The ratio is 4:1. Stir the raw materials, solvent, and entrainer to make them fully mixed.

[0049] Steps (4) and (5) of this embodiment are the same as steps (3) and (4) of Embodiment 1.

[0050] (6) The mixed solution separated by the first-level analysis is injected into the second-level analysis kettle by the delivery pump, heated by the jacketed heat exchanger, and continuously extracted by the vacuum pump group. -2 Under t...

Abstract

The invention relates to extraction solvent for extracting effective components from hop raw material and extraction and separation method thereof, wherein, the method for extraction and separation of hop extract and hop essential oil includes following steps as follows: (1) hop is filled in an extraction kettle and when the volume of raw material reaches 30 to 80 percent of that of the extraction kettle, feeding is stopped and a feeding-discharging control valve is closed; (2) a vacuum pump reduces the vacuum degree inside the extraction kettle below 1x10<4>pa to discharge the fixed gas from the kettle; (3) the liquid extract inside a solvent storage tank is fed into the extraction kettle till the hop raw material is completely immersed in the extract; (4) the extraction kettle is heated to maintain the temperature of the kettle between 10 DEG C and 50 DEG C, the extraction pressure between 0.4MPa to 2.0MPa and the extraction time between 40min to 60min and one-off immersion extraction is completed after filtration and separation of solid-liquid phase; (5) mixed liquid is fed into a temporary storage kettle through combined extraction and then is injected into an analytic kettle from the temporary storage kettle through a transfer pump; (6) mixed solution after primary analytic separation is injected into a secondary analytic kettle through the transfer pump to be heated through ajacket type heat exchanger and then is pumped continuously by a vacuum pump set; in addition, in the vacuum state of 1*10<4>pa-5*10<-2>pa, analytic evaporation of entrainer is completed and the entrainer is recycled after condensation by a recovery tank; meanwhile, the mixture of hop extract and hop essential oil is obtained inside the secondary analytic kettle.

Description

Technical field: [0001] The invention relates to an extraction solvent for extracting effective components from hop raw materials and an extraction and separation method thereof. Background technique: [0002] Hops are the basic raw material for beer production, and there are more than 200 known chemical components, and the unique chemical components include bitter substances α-acid, β-acid, hop essential oil and polyphenols. Wherein, α-acid (resin A or Humidone) is easily soluble in alcohol, ether, sherwood oil, insoluble in water, and its content in fresh flowers is 5-11%, and its content is greater than 6.5% in dry state; β- Acid (also known as B resin or lupulone) is soluble in ether and petroleum ether, insoluble in water, has a strong hop aroma, bitterness equivalent to 1 / 9 of α-acid, and antiseptic ability equivalent to α-acid 1 / 3 of hops, the content is more than 2.0% in dry state; hop essential oil exists in hop gland particles, which is yellow-green oily liquid, a...
