Through detection of temperature difference of different contour lines, the study and exploration of the relationship between the temperature difference of different contour lines and grain moisture content in the stacking and fermentation process of a traditional brewing process, and combination with the quality and yield of liquor brewed by the traditional brewing process, the minimum moisture requirements for liquor brewing raw material grain are obtained; and then the requirements that the temperature difference between region A and region B should conform are determined; and then the grain moisturizing effect can be obtained. The method has the advantages of quick and convenient operation, small labor intensity, short determination cycle, less equipment, low cost on determination, and accurate result.
Description
Technical field
The present invention relates to aromatic white spirit technology and brewing technology, especially a kind of method of passing judgment on profit grain effect.
Background technology
Profit grain is an important link of high-grade Maotai-flavor liquor method of making liquor.The object of profit grain is to make Chinese sorghum suction moisture, allows starch in Chinese sorghum realize tentatively to expand, the cell rupture of starch small grain, thereby discharges starch, for saccharification, fermentation provide material, therefore moistens the control of grain processing parameter and the success or failure that process operations is related to alcoholic.In actual production, due to reasons such as negligence of operations, cause moistening grain and finish rear Chinese sorghum water deficient, if the processing parameters such as now later stage boiling gelatinization do not adjust accordingly, can cause part grain to form intractable solids, to later stage work, increase difficulty and cause wastage of material.Therefore, the water content of being badly in need of the profit grain to finish rear grain is carried out rapid and accurate determination, differentiates in time grain and whether suctions moisture, thereby provide foundation for later stage processing parameter adjustment.
In the prior art, for the judgement of grain profit grain effect, be mainly by grain moisture content and Chinese sorghum surface-moisture number (be grain whether " receipts sweat ") judge whether grain suctions moisture.In traditional technology, the moisture determination of brewing materials (grain) is utilize to dry principle, the method length that expends time in, and need high temperature to dry, and the utilization of resources is many, thus effect that can not fast and convenient judge Chinese sorghum profit grain; And grain whether " receipts sweat " be that sense organ by people judges, although fast, individual impression there are differences, judged result is inaccurate.
Simultaneously, also having the patent No. is that the < < control method of water for brewing strong aromatic white spirit > > of CN201010567710.4 is to be X by defining cellar for storing things groove unstrained spirits water-content, upper rice steamer groove unstrained spirits water-content is Y, the relational expression that the mass percent that profit grain water is compared with grain is Z is that the method for Y=(0.742～0.772) X+ (0.086～0.088) Z+ (3.904～4.364) is calculated the moisture content relation in whole brewing process, this is one and controls and brewage moisture on the whole, its control method is comparatively complicated, and how be also difficult to detect the effect of profit grain, and at present in aromatic white spirit making method, profit grain effect does not also have pertinent literature to disclose by decision method how, only only have the pertinent literature that how to moisten grain to disclose.
Summary of the invention
In order to solve the above-mentioned technical problem existing in prior art, the invention provides a kind of method of passing judgment on profit grain effect, have that operation is fast and convenient, labour intensity is little, personnel amount and professional require plant and instrument low, that use few, judge the features such as cost is low, result is comparatively accurate.
Specifically be achieved by the following technical programs:
Pass judgment on a method for profit grain effect, after moistening grain and finishing, grain is stacked in heaps, and in heap, select two region A and B, and the temperature value in A and two regions of B is measured, and calculate the temperature head in two regions, according to temperature gap, judge profit grain effect, concrete operation steps is:
(1) defined area, heap top: stack the heap top that zymotechnique carries out grain according to traditional fermentation, and heap top grain is carried out to region division, the sea-bottom contour that vertical range is piled to 5-30cm place, grain surface, top is as a-quadrant, and the sea-bottom contour that vertical range is piled to 35-50cm place, grain surface, top is as B region;
(2) mensuration temperature accounting temperature are poor: adopt thermometer perpendicular to heap grain surface, top, to be inserted into a-quadrant and B region from heap grain surface, top, measure respectively temperature 1-20 time and record the temperature value in two regions, calculate respectively again the average temperature value in A and two regions of B, be recorded as respectively a and b, and with Δ T, represent the temperature head in A and B region, and calculate temperature gap according to Δ T=b-a;
(3) judge profit grain effect: according to the detection method that is related between traditional grain moisture content and Δ T ', and in conjunction with the minimum requirements to fermentation Measurement for Grain Moisture Content in making method, judge the maximum value of Δ T ', then Δ T and Δ T ' are contrasted, can determine the profit grain effect of grain.
Described a-quadrant and B region, wherein the least significant end in two regions is all 10-20cm with the vertical height on ground.
The present invention also provides a kind of method of passing judgment on profit grain effect to be applied to take Chinese sorghum, corn, wheat, paddy and brewages in the technique of aromatic white spirit as raw material.
Compared with prior art, there is following technique effect:
1. by employing, detect the temperature gap on different level lines, and in traditional fermentation technique, stack in fermenting process, temperature gap on different level lines and the relation of grain moisture content are carried out research and discovery, and the Quality and yield of the aromatic white spirit being brewed in conjunction with traditional making method, draw the requirement of the minimum water content of brewed spirit raw material grain, and then determine the requirement that the temperature gap in a-quadrant and B region should meet, then draw the situation of profit grain effect.
2. by the temperature gap on different level lines, calculate, obtain profit grain effect, its operation is fast and convenient, and labour intensity is little, and determination cycles is short, and plant and instrument is few, judges that cost is low, and result is comparatively accurate.
Accompanying drawing explanation
Fig. 1 is that the method that the present invention passes judgment on profit grain effect is chosen the diagrammatic cross-section in A, B region in grain heap.
Fig. 2 is the graph of a relation that the present invention passes judgment on Chinese sorghum single-detector and the temperature difference in the method for profit grain effect.
Embodiment
Below in conjunction with accompanying drawing and concrete embodiment, technical scheme of the present invention is done to further restriction, but claimed scope is not only confined to done description.
By traditional aromatic white spirit making method and empirical discovery, and pile top fermenation later in conjunction with grain profit grain, different isocontour temperature gaps and grain moisture content decline relation present negative correlation, in brewed spirit process, conventionally the moisture content of profit grain grain later should be higher than 37%, and the quality of white spirit being brewed is like this more excellent.
By take Chinese sorghum, carry out white wine production as raw material, the relation of research temperature gap and water content, when temperature gap Δ T ' is≤6 ℃, water content is more more than 37% Chinese sorghum later for profit grain, and then can meet preferably the Quality and yield demand of brewed spirit.
