Abstract

The invention relates the method of adjusting wine, comprising the following steps: 1 using common technology to squeezing grape, getting normal juice; 2 filtering normal juice; 3 separating from normal juice with hyperfiltration device, getting mixture of ethanol and water; 4 distilling mixture, separating ethanol and water; 5 putting the water from 4 into normal juice; 6 adding alcohol, and getting the product. The invention has the advantages of adjusting alcohol density, purifying wine, removing organic acid, and reducing yeast.

Description

A kind of method of regulating wine body

Technical field

The present invention relates to a kind of method of regulating wine body.

Background technology

Grape wine is the very high alcoholic drinks of nutritive value.Contain 23 seed amino acids according to one's analysis in the grape wine, and contain VB1, VB2, VB6, VB12, pantothenic acid, nicotinic acid and vitamin H.Though nearest discovers grape wine to healthy and helpful,, limited teenager, child-bearing period women and some patients and drunk vinous because vin ordinaire wine degree is that ethanol content is higher about 12 °.If can reduce wine degree vinous, make it to become a kind of masses and all like the low alcohol beverage drunk, must drive consumption vinous, further improve share of market vinous.At present, domestic production low-alcohol wine method is concluded four classes: stop alcohol method of formation, heat treating process, raw material hypoglycemic method, multiple bacteria compound fermentation method.Domestic brewery is how with stopping the alcohol method of formation, but its fermentation not exclusively, has in the grape wine in a large number not by fermenting carbohydrate, and mouthfeel is sweeter, and local flavor is also relatively poor; Though it is under the vacuum tightness of 4～20Kpa in absolute pressure that pure method falls in heat treating process fermentation finished thoroughly1, thermal treatment, 30 ℃～35 ℃ vaporization temperature is influential to quality vinous; Raw material hypoglycemic method is to utilize freezing method to remove the method for selecting suitable bacterial classification to ferment again after the part sugar in the Sucus Vitis viniferae, complex process, and the local flavor control of wine is also difficult; The multiple bacteria compound fermentation method is by selecting multiple bacterial classification mixed fermentation to reduce the growing amount of alcohol, and alcohol is transformed the method for ester class or other materials.If the screening of bacterial classification is suitable, can produce the low preferably pure wine of quality, but this method is restive.

Summary of the invention

Problem at above-mentioned existence, the object of the present invention is to provide a kind of method of regulating wine body, this production technique can be regulated ethanol concn, and grape wine carried out the purifying classification, takes off organic acid, falls processing such as yeast, can when reducing vinic alcohol concentration, not influence the fragrant mouthfeel and the local flavor of wine.

For achieving the above object, a kind of method of regulating wine body of the present invention comprises the steps:

1) adopt routine techniques with grape extraction juice and fermentation, to obtain grape wine Normal juice;

2) grape wine Normal juice is filtered the granule foreign in the filtering grape wine Normal juice through filter;

3) from grape wine Normal juice, isolate the mixed solution of second alcohol and water again by reverse osmosis unit;

4) mixed solution to the isolated second alcohol and water of step 3) carries out the lower boiling distillation, and the second alcohol and water is separated;

5) water that step 4) is obtained returns in the grape wine Normal juice filtered liquid that joins step 3);

6) ethanol concn vinous that obtains according to step 5) adds alcohol according to processing requirement, thereby regulates alcoholic degree vinous.

Further, the molecular level of the reverse osmosis membrane in the described reverse osmosis unit is 60, and the operation operating pressure is at 1.5～2.5Mpa, and system's Minimum Flow Control is at 6～8m ³/ hr.

Further, described strainer comprises two-stage filtration, and the filtering pore size filter of the first step is 4～6 μ, and the filtering pore size filter in the second stage is 0.5～1.5 μ.

The present invention can regulate ethanol concn, and grape wine carried out the purifying classification, takes off organic acid, falls processing such as yeast, do not changing under initial sugared concentration and the isoparametric situation of fermentation time, can when reducing vinic alcohol concentration, not influence the fragrant mouthfeel and the local flavor of wine again.

Description of drawings

Fig. 1 is a production equipment structural representation of the present invention.

Embodiment:

As shown in Figure 1, after grape is squeezed the juice and is fermented through prior art, be stored in the Normal juice jar 1, be transported to

first strainer

3 and 4 filtrations of second strainer successively by raw water pump 2, remove the granule foreign in the grape wine Normal juice, the pore size filter of first strainer 3 is 5 μ, and the pore size filter of second strainer 4 is 1 μ; Grape wine Normal juice after process is filtered is transported to by topping-up pump 5 and high-pressure pump 6 carries out reverse-osmosis treated in the reverse osmosis unit 7, it is the reverse osmosis membrane of SE4040C that the film of reverse osmosis unit 7 is selected commercially available model for use, the molecular level of reverse osmosis membrane is 60, the operation operating pressure is at 1.5～2.5Mpa, and system's Minimum Flow Control is at 6～8m ³/ hr; Isolate ethanol and Sucus Vitis viniferae through reverse osmosis unit 7, receive by ethanol receiving tank 8 and Sucus Vitis viniferae receiving tank 9 respectively; The ethanol that ethanol receiving tank 8 receives is isolated alcohol and water by lower boiling water distilling apparatus 12 again, and receives with alcohol container 14 and water pot 13 respectively; Isolated water returned again join, measure the ethanol concn vinous that obtains at last, add alcohol according to processing requirement, thereby reached the purpose of regulating wine body through in the reverse osmosis unit 7 isolated Sucus Vitis viniferaes.

Can work preferably in order to make reverse osmosis unit 7, on reverse osmosis unit 7, washing unit can also be installed, comprise cleaning case 10 and scavenging pump 11, the input terminus of cleaning case 10 links to each other with two input terminuss of reverse osmosis unit 7 respectively, and the output terminal of cleaning case 10 links to each other with the input terminus of reverse osmosis unit 7 by a scavenging pump 11.When needing to clean, close the production circuit, reverse osmosis unit 7, cleaning case 10 and scavenging pump 11 are communicated with, utilize aqueous ethanol or isolated Sucus Vitis viniferae that reverse osmosis unit 7 is cleaned.
