The society calculates corn water content, autumn sells grain to not be duped!
Agrotechnical
At present, corn enters the crown of the year in succession, farmer friend arrived to sell the time of autumn grain again, the corn crop this year is not quite good, but must curry favor with, do not let grain dealer play tricks give pit again. When selling corn, the water content of corn meets those who affect corn buy the price, but a lot of farmer do not understand the water content that how should judge corn. We know the way with the judgement method of corn water content and grain scurvy dealer below.
One look, the microgroove of coping of corn seed bead states corn works more more more.
2 catch, catch bead of a corn to grasp, outside the corn with much excessive is drier.
3 bite, the sound when the tooth is bitten is ringing, the corn seed bead of bar tooth is drier.
4 look, plumule is dry, do white, traverse into flour shape, state moisture is about 13% .
5 clutch, with fingernail clutch maize sunken edge of ministry upside both sides, have bit of mark a bit, state moisture is about 14% ; If the mark is bigger, have broken skin appearance, moisture is about 15% ; The maize that be like clutch is carried on the ministry hair is soft, bead look is dark, moisture is about 16% .
14% less than: Seed bead color is normal, bite with the tooth have shake feeling and ringing noise, broken bead size is differ, section is smooth. Use hand grab or insert the caboodle that eat food from time to tome icy " hand of Buddhist templeput on the brakes " feeling, can have when churning inside caboodle " clang clang " ringing sound. Embryo ministry caves, sere stick a bottom.
15%-16% : Seed bead color is normal, bite with the tooth have shake feeling, noise is not ringing, when use hand grab or churning icy but not " hand of Buddhist templeput on the brakes " , embryo ministry systole caves, with finger but slight clutch is entered, fingernail brim has splendent oil stains.
17%-19% : Seed bead facial expression is new, the tooth is bitten from time to tome noise, not shake tooth. Embryo ministry has cave, with fingernail very easy clutch is entered, fingernail contains wet trace.
20%-24% : Seed bead become damp, color is bright-coloured luster. Move voice with the hand grave, feel tide is acerbity, the feeling when the hand is inserted to corn caboodle has resistance. Embryo ministry and bead face are made the same score basically, when the tooth is bitten brittle, have grave sound a bit or do not have noise, broken broken bits often is together repeatedly.
25% above: Seed bead is damp, color is bright-coloured, burnish is strong shine. Embryo ministry full or have a bit protuberant, when be being bitten with the tooth very easy squash, without noise, the hand inserts grain very hard inside caboodle.
30% the left and right sides: Seed bead moisture, go up big, bead color is bright-coloured and bright, embryo ministry expands protuberant, with ministry of fingernail clutch embryo waterlogging goes out.
With 30% for exemple:
A moisture deducts 1.5(enterprise to differ deduct the coefficient that fold caustic to differ)
30-14.5=15.5
15.5 × 1.5=23.25
100 jins of commissariat are buckled give 23.25 jins!
The price of different moisture content is different, but the price that thinks convert becomes standard moisture content, for instance, 30% corn price is content 990 yuan / ton, is according to the country second-class corn water divided (how much is the market price case of 14.5%) ? It is so:
1000kg × (1-30%)=700kg=990 yuan. So 700 ≈ of 900 ÷ 1.286 yuan every / jin
1000kg × (1-14.5%)=855kg. So ≈ of 855 × 1.286=1099.53 1100.
Be in for instance: Price of corn safety water is 1500 yuan a ton, safe water 14% , so excuse me the how many money of 28% a ton that?
The price of anhydrous corn: 1500/(1-14%)=1744.186
So you receive the price of 28% corn to be 1744.186X(1-28%)=1255.8
Again for example: Corn 35 water, stoving arrives 15 water, 100 jins of commissariat return meeting remnant how many jins, is calculative method what?
(35-15)X1.5=30 jin, 100-30-=70 jin. Remnant of 100 jins of corn 70 jins.
Press formulary 100X(100-35)/(100-15)=76.5 jin
Corn moisture and price computation are formulary:
Wet grain price / [moisture of 1-{(wet grain - }/100]= of 14)* discount scale loses dry value
The judgement method that corn water content is above and method of conversion of corn moisture content, when farmer is selling food, can oneself judge corn first probably water content, avoid to be deceived.
Arrive every year fastigium selling food, always dealer of a few grain thinks up all sorts of caustic to draw on hole farmer. What deceitful trick can they often use?
1. pulls the paddy that him dealer of the grain on grain car brings, wanted to notice, have a problem.
2. pulls grain there is dark style water tank below the car, check is over turn on the water on road of empty wagons skin.
3. pulls aperture of grain vehicle big case to have sand.
Above is a kind of means 3 kinds, it is underhand method is used on weight. When farmer friend is selling food, must be in check empty wagons when get on a car to look, follow at the back of the car that drives oneself next, prevent turn on the water on the road, discharge sand, cannot let receive the car foregone of grain person stoutly.
4. electron is disturbed implement, disturb weighbridge.
Avoid measure, balance of a small electron is put on ground pound limit, show jin of number to be not moved, observe jin of several change when selling food.
There is dark layer on 5. camion, can take away 1200 jins of or so paddy.
After commissariat assembles a car, best microscope good camion.
Above is the deceitful trick that cheater has used, when everybody sells food, must notice, the commissariat that does not let work laboriously plant is cheated by cheater.
Here, small make up remind broad farmer the friend raises vigilance, do not give cheater existent chance, maintain self interest, commissariat sells superior price.
