Abstract
A process for extracting hop extract from hot partides by supercritical back extraction with CO2 features that the broken hop particles are loaded in multi-layer raw materials container and then put in extracting reactor for back extraction with supercritical CO2 at 58 deg.C and 22 MPa for 2-3 hrs, and separation step is them performed at 20 deg.C and 5 MPa. Its advantages include high output rate (13.6%), high alpha-acid content (41.0%), high extraction rate (92.8%), short period and low consumption of CO2.
Description
The present invention relates to a kind of supercritical CO
2Extract the technology of hop extract, particularly a kind of supercritical CO
2The back extraction method is extracted the technology of hop extract (Hop Extracts) from pellet hop.
Hops (Hop) is the main raw material of brewing industry, for solving problems such as the transportation and the storage of guaranteeing the quality, product innovation forms such as hops particle, hop extract, different hop extract appear in succession, wherein, hop extract is the main product innovation that replaces hops always, is subjected to the favor in market.At present, the method of extracting hop extract mainly contains three kinds: the one, with organic solvent extraction hop extracts such as hexane, ethanol, methylene dichloride, because organic solvent poor selectivity, in extraction process, useless hardened resin, wax are extracted, and the fragrance of a flower essential oil of also filling a wine cup for when organic solvent is removed in distillation is removed the local flavor that has destroyed beer, simultaneously, remaining organic solvent works the mischief to human body.The 2nd, liquid CO
2Extract the method for hop extract,, cause energy consumption big, the cost height because of the big separation efficiency of solute resistance to mass transfer in liquid is low.The 3rd, supercritical CO
2Extract the hop extract method, this medicinal extract is possessed the effective constituent of hops, does not contain hardened resin and wax, does not contain nitrite, and no solvent residue is free from environmental pollution.But traditional forward extraction method is still continued to use in its extraction, and promptly hops are contained in the extraction kettle of individual layer charging basket, CO
2Flow from bottom to top, hops are at the still inner suspension, and air-teturning mixed phenomenon is serious, has reduced extraction efficiency, has prolonged the extraction time, has increased energy consumption, and cost is increased, and quality product is very not satisfactory.
The purpose of this invention is to provide a kind of supercritical CO
2The back extraction method, the technology of extraction hop extract from pellet hop.The characteristics of this technology are in the multilayer barrel of the pellet hop patent No. ZL99201463.8 that is contained in the inventor, carry out supercritical CO
2Oppositely (in the extraction kettle from top to bottom) flows, and promptly adopts the technical process of the inventor's number of patent application CN-00121565.5, extracts hop extract under the temperature of setting, pressure.The advantage of this technology is: 1, the multilayer barrel makes material bed pressure distribution even, and pressure reduction is little, no air-teturning mixed phenomenon, and mass transfer is fast, the efficient height.2, CO
2Back extraction, the time is short, and energy efficiency is remarkable, is fit to suitability for industrialized production.
Embodiment of the present invention are as follows:
Shown in the processing unit schema that Fig. 1 extracts hop extract: will be crushed to 1-1.2mm, remove the pellet hop of dust, install to the multilayer barrel, put into extraction kettle (E1, E2, E3), open the reverse flow valves V10 of control E1, E2, V13, V14, V17 and corresponding V4, V7, V23 and V25 carry out E1, the extraction of E2 differential concatenation.The processing condition of extraction are: starting heater H 1, a few C02 pump of H2 P1, to make extraction kettle pressure be 22 ± 2MPa, 58 ± 2 ℃ of temperature, and separating still A1 pressure is 5 ± 1MPa, temperature 20-25 ℃, CO
2Flow velocity 3-5Kg/Kg.Hr extracted after 2-4 hour, and separating still A1 emits hop extract, sampling analysis.Then, stream switches to E2, the extraction of E3 differential concatenation: close V4, V7, V23, E1 unloads charging; Open V18, V21 and V5, V8, V24.And the like, carry out two still differential concatenation continuous extractions.
Advantage of the present invention: 1, equipment flowsheet is simple, only increases valve, pipeline and just can carry out reverse continuous extraction, and percentage extraction obviously improves.2, the multilayer barrel makes material bed pressure distribution even, and pressure reduction is little, no air-teturning mixed phenomenon, and mass transfer is fast, the efficient height.3, good product quality keeps the whole effective constituents of hops, and is free from environmental pollution, significantly energy-saving and cost-reducing.
Following preferred embodiment describes supercritical CO in detail in conjunction with Fig. 1
2Oppositely extract the technology of hop extract, but do not mean that and limit the scope of the invention.
