Abstract
The invention belongs to the technical field of liquor making, and provides a gas-phase temperature change-based on-line quality-measuring liquor receiving process by improving the traditional liquor receiving method. The process comprises steps as follows: the gas-phase temperature of distilled liquor is monitored on line by a temperature transmitter above a cover outlet of a grain distiller; data of the gas-phase temperature is transmitted to a DCS (distributed control system) in real time; the DCS compares the real-time gas-phase temperature data and preset temperature data; and when the gas-phase temperature data is equal to the preset temperature data, the DCS controls an automatic regulating valve at a liquor receiver to be automatically opened or closed. The invention breaks through the traditional experience of liquor receiving through flor watching, improves the automatic operation degree, reduces the manual error and increases the yield of high-quality liquor.
Description
Technical field
The invention belongs to brewing technical field, be specifically related to gas phase temperature and change online amount quality picking wine technique.
Background technology
Amount quality picking wine is an important technological operation in White wine brewing process.Amount quality picking wine is exactly after foreshot's extraction, tastes accurately classification while plucking.Different amount quality picking wine processing methodes, has a great impact the quality of white wine, should control stream wine temperature, and slowly distillation, leaves out the beginning and the end.
At present, wine brewing operator pluck wine experience in the tradition of plucking extensively employing in wine process " by eyes observation hops changing conditions, wine body odour, aroma change " and pluck wine.But tradition is plucked wine and is had following shortcoming:
1. see that it is the traditional technology that in white liquor distilling process, operator grasp wine degree height that flower is plucked wine, according to the shape of hops, size, time length, can judge the height of wine liquid alcohol molecule content.But there is larger difference in interpersonal micro-judgment.The quality of plucking wine affects the yield of quality liquor largely, and at present, quality liquor yield is only 1.5 ~ 2.2%.
2. see that it is the mixing solutions of the alcohol based on various concentration and water that flower is measured, different with the surface tension at temperature at certain pressure, the foam that alcohol produces easily dissipates because tension force is little.Along with the rising of distillation temperature, ethanol concn reduces gradually, and the dissipation speed of the hops that alcohol produces constantly slows down, and the relative density of water is greater than alcohol, and tension force is large, and the dissipation speed of spray is slow.See that flower can be divided into 5 kinds: large blowing, little blowing, cloud flower, two flowers, oil bloom.But in stream wine process, hops and spray change very fast alternately time, and interpersonal micro-judgment exists larger difference.Likely cause excellent section of wine to enter one section or one section of wine and enter the intermixing such as excellent section, affect vinosity.
As CN201110089637.9, name is called the application for a patent for invention of " method of storing Luzhou-flavor liquor ",
Disclose a kind of method of storing Luzhou-flavor liquor, it is characterized in that comprising the following steps: a, by vinasse loaded steamer steam wine; B, start stream after drinking, stream wine temperature is controlled to 25 ~ 35 degrees Celsius, get first paragraph wine, assorted aldehyde taste in wine body etc. taste is extractd totally; After c, one section of wine are won, it is two sections of wine that stream wine to hops turn little Hua, 25 ~ 35 degrees Celsius of stream wine temperature; After d, two sections of wine are won, it is three sections of wine that stream wine disappears to hops, 25 ~ 35 degrees Celsius of stream wine temperature; E, three sections of wine are got four sections of wine after winning, get while flowing out the alcoholic strength of wine to 0%vol and stop, 25 ~ 40 degrees Celsius of stream wine temperature.
Although the wine method of plucking of this patent has been controlled the stream wine temperature of plucking wine, but still adopt traditional flower of seeing pluck wine and see to spend to measure and pluck wine, thereby still exist personal errors to affect yield and the vinosity of wine.
