Abstract
The invention provides a freeze-thawing and extruding and dissolve-promoting technique for biological materials, including that: the biological materials especially containing tea, glossy ganoderma,rhizoma gastrodiae and the like, are frozen in the freezing equipment at a temperature below zero DEG C, the frozen biological materials are input the feed head of double-screw extruding-puffing machine after pulverized or directly, the power of double-screw extruding-puffing machine is controlled and the temperature of the feed head is controlled between 20 DEG C and 70 DEG C, the biological materials are gradually in the high-pressure state in the double-screw extruding-puffing machine, and the temperature of biological materials rises because of the pressure, the biological materials are in the normal-pressure or negative-pressure state in an instant time, in this way, the low-temperature state effectively promotes the wall breaking of various cells in the biological materials and the quick dissolving of effective components.
Description
Technical field,
The present invention is the technique for freeze-thawing, extruding and promoting dissolution of biological raw material, and low-cost high-efficiency promotes the stripping of biological raw material active ingredients such as tealeaves, glossy ganoderma, rhizoma Gastrodiae at ambient temperature, is processed into the room temperature instant product.
Background technology,
Contain up to nearly thousand all in the biological raw materials such as tealeaves, glossy ganoderma, rhizoma Gastrodiae to human body beneficial's composition, with water is that these active ingredients of solvent extraction have two technical barriers, the one, need high temperature ability rapidly dissolvable more than 90 degrees centigrade, the 2nd, high temperature is easy to destroy the active ingredient in tealeaves, glossy ganoderma, the rhizoma Gastrodiae again.If extract these active ingredient with organic solvent, to biological raw material eventually last product and environment pollution is all arranged, tealeaves research institute of the Zhejiang University beam moon flourish and; Good a kind of method for extracting effective content of tea of having invented is built in the land, application (patent) number: 200410089179.9, promptly under cryogenic conditions, utilize ultrasonic concussion to extract effective content of tea, their scheme is when conventional low temperature 45-50 ℃ of lixiviate tealeaves, a frequency is placed extractor for the 40khz ultrasonic generator, in stirring and leaching, open ultrasonic generator, their technology, the tea component dissolution velocity is more fast again than conventional low temperature, and extraction time can shorten half, it is good that the extract local flavor keeps, but in suitability for industrialized production, the acquisition of high-power ultrasonics is had any problem, and also has the high problem of cost; The cold extraction method of a kind of effective content of tea of qin invention is kept in one 401 in No. 142 No. 15 building, People Street, Changchun City, Jilin Province, application (patent) number: 02132857.9, it is a kind of cold extraction method at ambient temperature, this method is to be raw material with tealeaves, with water or ethanol, ether, benzinums etc. are done extraction solvent, with above-mentioned raw materials, after the solvent, in pressure vessel, at room temperature carry out HIGH PRESSURE TREATMENT, pressure 〉=100MPa, dwell time 〉=5 minute, filtering tealeaves after the release, promptly obtain the extract of effective content of tea, his method shortcoming is to need to use the high pressure container, also causes production cost to rise.
The technique for freeze-thawing, extruding and promoting dissolution that the purpose of this invention is to provide biological raw material, utilize twin-screw extruder that the biological raw material that is in freezing state is produced high pressure, extrude the back by discharging opening and moment enter atmospheric pressure state, cell freeze thawing, high pressure is short molten, the short cell wall breaking technology of pressure contrast combines in same procedure and equipment, and low-cost high-efficiency promotes the stripping of biological raw material active ingredient at ambient temperature.
The technical solution adopted in the present invention is: will be particularly including tealeaves, glossy ganoderma, rhizoma Gastrodiae is at interior fresh biological raw material, certainly also dried biological raw material can be soaked Run with cold water soaks, be placed in the freezing equipment below 0 degree centigrade and make it freezing, the biological raw material that is freezing state is imported or is directly imported the charging aperture of twin-screw extruder through the pulverizing back, the power power of control twin-screw extruder, the temperature of discharging opening is controlled between 20 to 70 degrees centigrade, material is in high-pressure state after entering twin-screw extruder gradually, and, pressure raises owing to causing temperature, extrude the back by discharging opening and moment enter normal pressure or negative pressure state, biological raw material is in this procedure, short time has been experienced three processes, 1, the freeze thawing of cell, cause cell wall rupture, discharge active ingredient, 2, the high pressure that twin-screw extruder produces further promotes the active ingredient stripping, 3, the material ejection, pressure moment reduces, powerful pressure contrast causes cell wall rupture once more, just effectively promoted the broken wall of the various cells of biological raw material like this at low-temperature condition, the quick stripping of active ingredient.
Be described in detail the production technology of technical scheme that the present invention adopts below:
First embodiment, the charging aperture of freezing biological raw material input twin-screw extruder, simultaneously to an amount of clean water below 70 degrees centigrade of charging aperture input, increase the stripping of biological raw material active ingredient in extrusion process, the power power of control twin-screw extruder, make the discharging opening temperature between 20 to 50 degrees centigrade, the extrudate of discharging opening need continue the processing of purifying, extrudate directly enters in the container, adopt existing biological raw material extracts active ingredients scheme to purify, as centrifugal, membrane filter method, effective component extractings such as exchange resin method are made relevant tea product again;
Second embodiment, freezing biological raw material enters the charging aperture of twin-screw extruder, by control power power, make twin-screw extruder discharging opening temperature between 50 to 70 degrees centigrade, connect closed container at the twin-screw extruder discharging opening, closed container is communicated with negative pressure of vacuum equipment, promotes the low temperature expanding of extrudate by negative pressure, extrudate directly becomes dilated product, and this is an optimum implementation of the present invention;
The 3rd embodiment, freezing biological raw material enters the charging aperture of twin-screw extruder, simultaneously to an amount of carbon dioxide dry ice of twin-screw extruder charging aperture input, can increase expanded under lower temperature conditions of the stripping of biological raw material active ingredient in extrusion process and extruded material like this, by control power power, make the discharging opening temperature between 50 to 70 degrees centigrade, extrudate directly becomes dilated product;
The 4th embodiment, freezing biological raw material enters the charging aperture of twin-screw extruder, simultaneously to an amount of liquid alcohol of twin-screw extruder charging aperture input, can increase expanded under lower temperature conditions of the stripping of biological raw material active ingredient in extrusion process and extruded material like this, by control power power, make the discharging opening temperature between 50 to 70 degrees centigrade, extrudate directly becomes dilated product.
This dilated product has stable network structure, and is can the long period in water not defeated and dispersed, can directly brew with warm water or cold water and drink, and also this dilated product can be ground into smalls, is packaged in the osmotic bag, brews with warm water or cold water and drinks.
