Description
Technical field
The present invention relates to a kind of measuring method of grain moisture content, a kind of seven minutes method for measuring grain moisture content, the invention still further relates to the special measurement equipment adopting the method specifically.
Technical field
Water percentage, as an important quality index of grain, directly has influence on the links such as the purchase of grain, sale, allocation and transportation, storage, processing, measures grain moisture content very great concerning meaning grain department.How to measure grain moisture content fast, accurately, easily, be a global problem, and present international grain measurement of moisture content method is a lot, mainly contains three kinds from its measuring principle point:
The first: its advantage of international standard oven drying method is: principle is reliable, accuracy is high, reproducible; Shortcoming is: complex operation, Measuring Time long (about 120 minutes).
The second: resistance, electric capacity aquametry, its measuring principle is using grain as a kind of medium, according to the change of its water cut, causes the change of resistance, electric capacity, is then the moisture value display of sample transform electrical signals.LDS-H, LDS-P, SWS-5A type etc. produced by the PM8188 type that product has strong 12 types of Supreme Being produced in USA, Japanese Kate company produces, Chinese Shanghai Qingpu.Properties of product: these ice detectors have a common ground to be exactly that measuring speed fast (3 minutes), volume are little, easy to carry.Weak point surveys water scope little (only can survey the grain of below 20% moisture), requirement corresponding conditions is high, the factor that is disturbed many (as: temperature, density, vibration etc.), cause its error like this, repeat difference bigger than normal, repeat difference and maximumly reach 0.8%, error is maximum reaches 3.5%.
The third: infrared heating aquametry, its measuring principle utilizes infrared high-temperature to heat, and in the short time, (about 10 minutes) are by clean for the evaporation of the moisture of sample, and the moisture weight of weightlessness is conversed percent water rate.Product has: Japanese Kate company produces FD610, FK720, Germany produces MA30, China Shenzhen produces SFY-20 type, and Shanghai produces DHS-16A type etc.The advantage of these ice detectors is that sample moisture is weightless fast, overcome the impact of most of disturbing factor, but when its fatal shortcoming is high humidity heating, not only there is moisture to evaporate, also have the loss of volatility dry, different samples, the amount of dry loss is different, thus causes measurement data unstable, and error, to repeat difference large, repeat difference and maximumly reach 1.3%, error is maximum reaches 2.3%.
Can find out that measurement is inaccurate fast from above three kinds of methods, measure not quick accurately.
Summary of the invention
The object of the invention is to provide that a kind of measuring speed is fast, good stability, high, simple to operate, the noiseless factor impact of accuracy, seven minutes method for measuring grain moisture content of losing without dry and measuring equipment thereof.
The object of the present invention is achieved like this: the method comprises the following steps:
1., water conservation pulverizes, and by the quantitatively box-packed tested grain samples removing clean impurity, pour in comminutor after striking off, start is pulverized, and the time of pulverizing is 50 seconds, after auto stop, pours out sample for subsequent use.
2., weigh, the balance pan of a steelyard empty ware box being put into weighing data processor weighs tare weight, and by tare weight data storing on the tare weight position of weighing data processor display screen, press peeling key and balance is shown weight clearing, by step 1. in ready sample load in ware box and weigh example weight, example weight Data Control in 2.000 ~ 2.100g scope, after weighing data is stable, data storing reality weighed, to the heavy position of sample of display screen, takes off ware box.
3., dry, by step 2. in the ware box that takes off put into drying baker constant temperature drying 7 minutes at the temperature of 120 DEG C, drying baker takes out after reporting to the police, and checks the number and covers ware lid, is put into after fast cooling on marble slab cools 2 minutes and weighs.
4., dry after weigh, by step 3. in cooled ware box be put on weighing data processor balance pan of a steelyard and weigh, weighing data is stored into display screen " gross weight " position, weighing data processor will automatically calculate and show moisture value;
Step 4. described in moisture value computing formula:
Moisture value computing formula:
Wherein
X---moisture (%)
W
1---sample-containing dish box tare weight (g)
W---sample heavy (g)
W
2---sample-containing dish box and sample heavy (g) after drying

B---moisture correction constant, B span is 0.10 ~ 1.40, and optimum value is 0.50;
5., go out result, printing, press the printing key on weighing data processor after moisture value display, print moisture value result, complete whole measuring process.
A kind of seven minutes measuring grain moisture content equipment, this equipment comprises:
A vertical moisture-holding crushing machine, a quantitative box, a weighing data processor, ware box, a drying baker.
The present invention has the following advantages and good effect:
1, the inventive method and GB oven drying method contrast, and principle is identical, accuracy is suitable, and unlike shorter than National Standard Method drying time ,≤16.0% moisture sample dries 7 minutes, and National Standard Method dries 40 minutes; > 16.0% moisture sample, only dry 7 minutes, GB oven drying method dries 80 minutes.Cool time is short, only cooling 2 minutes, and GB cools 15 minutes.Simple to operate, no matter much moisture samples are only dried once, National Standard Method > 16.0% moisture sample will be dried at twice.Automatic calculating need not manually calculate, and National Standard Method needs artificial calculating.
2, the inventive method and resistance, electric capacity aquametry contrast: measuring speed is suitable, 120 DEG C of 7 minutes aquametry principles are more reliable, good stability, high, the noiseless factor impact of accuracy.
3, the inventive method and infrared heating aquametry contrast: measuring speed is fast, good stability, accuracy are high, lose without dry.Ensure that not only fast but also accurate.
