A kind of production method of grape wine
Technical field
The present invention relates to technical field of producing vinous.
Background technology
China's grape wine starts so far from 1892 Nian Zhangyu companies, all production white wines, red wine, extraordinary ethanol content vinous are all less than surpassing 24 degree, emergence along with world's liquor, the VSOP obtaining after fermented distilled with Fructus Vins juice (VERY SUPERIOR OLD PALE, VSOP) alcoholic strength is in 35-40 degree left and right.Adopt tower distillation brandy to be adopted by countries in the world, in still-process, different according to the polarity of volatilization goods and materials, wherein a part intactly enters effluent liquid (higher alcohols), a part changes into lactic acid second fat fourth two fat, benzene 2 second fat, or yeast discharges fatty acid ethyl ester macromole lipid acid, domestic all production cognac manufacturing enterprise adopts the interval type distillation mode of going " wine is pinched tail wine ", in operating process, be difficult to control flow, Heating temperature, and control flow and Heating temperature are to cognac, production plays decisive role, again because distillation temperature is more than 70 degree, havoc the nutritive ingredient of original grape juice, cause taste souring vinous, the smell is awful.The alcohol-free degree Normal juice of all factories after extracting alcohol, because process technology limit is all made discharge of wastewater, has a strong impact on environment, has also caused loss to enterprise.
Summary of the invention
The object of this invention is to provide and a kind ofly in producing technical process vinous, adopt new cryogenic distillation method, extract nutrition and medicine price cheating value that higher alcohols (alcohol) retains original grape juice, solve grape fermentation Normal juice separating-purifying core technology.
The object of the invention is to be achieved through the following technical solutions:
Production of Wine method of the present invention, the method comprises:
Step 1: maturation is carried out to destemming fragmentation without the grape of decayed fruit, by spiral pump, material is sent into prefermentor;
Step 2: to adding polygalacturonase and carbonic acid gas in prefermentor, get juice after clarification precipitation and enter secondary fermentation tank;
Step 3: add bacterial classification and nutrient substance in secondary fermentation tank, temperature control is cultivated to saccharification and finished, and pours in down a chimney into ageing district and deposits ageing;
Step 4: the Normal juice after ageing is entered to rectifying tower raw material and deposit tank;
Step 5: by turnover material heat exchanger, Normal juice is carried out to preheating, inject the sparger distillation of rectifying tower stage casing with fresh feed pump and after metering, isolate the grape juice beverage of grape spirits and soft degree;
Step 6: grape spirits is blent, entered filling district after ageing, freezing treatment, membrane filtration;
Step 7: packing, detects warehouse-in.
Concrete, in above-mentioned step 2, also comprise:
Step 21: with squeezing machine, the skin slag staying after clarifying is got to juice, juice enters prefermentor;
Step 22: grape white wine is got in the Pi Zharu solid state fermentation district steaming of getting after juice.
As preferably, in above-mentioned step 3, in secondary fermentation tank, with 25~27 ℃ of constant temperature, cultivate 30 days, pour in down a chimney that into ageing district, to deposit the ageing cycle be 6 months.
As preferably, in above-mentioned step 5, also comprise:
Step 51: adopt in tower and clamp the section of heating, constant temperature zone, condensation segment, sectional temperature-controlled;
Step 52: vacuum pump extracting vacuum, carry out low-temperature distillation, separated methyl alcohol, formaldehyde, potato spirit are added to and in Water-ring vacuum injector, carry out timing recovery with the vacuum extracting.
As preferably, in above-mentioned step 5, adopt continuously feeding mode, according to the difference of molecule proportion and boiling point between material different components, segmentation separating high-purity grape spirits, the original grape juice of soft degree outputs to finished pot through pump at the bottom of tower.
As preferably, in above-mentioned step 5, adopt Stainless Steel Cloth structured packing, sparger, collector, the long-range measuring point of constant temperature, pressure-measuring-point, liquid level measuring point and vacuum tightness pressure-measuring-point are set.
As preferably, to soft degree Normal juice in going out tower flow process, carry out freezing treatment, and sealing is preserved.
As preferably, after blending, above-mentioned step 6 pair grape spirits carries out deodorization, depickling and removing carbon dioxide impurity.
As preferably, in above-mentioned step 6, adopt 1 micron membranes to filter.
The useful technique effect that technique scheme of the present invention reaches: adopt low-temperature fractionating tower distillation technique, the materials such as the harmful methyl alcohol of sub-department, formaldehyde, guarantee to drink safety; Low temperature has guaranteed effective constituent and the genuineness of wine; In the technical process of sealing, distill higher alcohols, avoid air, personnel or the pollution of other implements to material, guaranteed the quality of higher alcohols and nonalcoholic original grape juice, made nonalcoholic original grape juice can make grape juice beverage, avoided waste and contaminate environment.
Embodiment
Disclosed all features in this specification sheets, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this specification sheets (comprising any accessory claim, summary), unless narration especially all can be replaced by other equivalences or the alternative features with similar object.That is,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
A kind of disclosed Production of Wine method in embodiments of the invention, the method comprises following step:
Step 1: maturation is carried out to destemming fragmentation without the grape of decayed fruit, by spiral pump, the material after fragmentation is sent into prefermentor;
Step 2: material and auxiliary material are stirred, to adding polygalacturonase in the material of prefermentor, and to injecting carbon dioxide in prefermentor, clarify and get juice after precipitation and enter secondary fermentation tank;
Step 3: add bacterial classification and nutrient substance in secondary fermentation tank, temperature control is cultivated to saccharification and finished, and pours in down a chimney into ageing district and deposits ageing;
Step 4: the Normal juice after ageing is entered to rectifying tower raw material and deposit tank; After entering rectifying tower raw material and depositing tank, just can pass through follow-up distillation process; Rectifying tower raw material is deposited between tank and rectifying tower and is connected by pipeline, therefore can avoid air and the pollution of personnel to material.
Step 5: by turnover material heat exchanger, Normal juice is carried out to preheating, inject the sparger distillation of rectifying tower stage casing with fresh feed pump and after metering, isolate the grape juice beverage of grape spirits and soft degree;
Step 6: grape spirits is blent, entered filling district after ageing, freezing treatment, membrane filtration;
Step 7: packing, detects warehouse-in.
As preferably, above-mentioned step 2 also comprises:
Step 21: with squeezing machine, the skin slag staying after clarifying is got to juice, juice enters prefermentor;
