What exactly does it mean when purchasing corn?
The state stipulates that the moisture content of temporary storage corn must not exceed 14% to be qualified corn. Every time it exceeds 1%, the quality of the corresponding moisture will be deducted. For example, the moisture content of 100 kilograms of corn is 16%. If it exceeds 2%, the real corn quality is: 100 kilograms - 100 kilograms X 2% kilograms = 98 kilograms. If the price of corn is 1.5 yuan/catty, then 98 catties should be sold x 1.5 yuan/catty = 147 yuan.
The purchase price of corn for national temporary storage is 1.11 yuan per pound of standard product. The national standard third-class corn produced in 2014 is used as the standard product. The specific quality standard is:
Test weight 650 grams /L ~ 685g/L (including 650g/L, excluding 685g/L); the content of imperfect grains is within 8.0%, of which moldy grains are within 2.0%; the moisture content is within 14.0%; and the impurities are within 1.0%. The price difference between adjacent grades is 0.02 yuan per catty.
The listed purchase price refers to the delivery purchase price at the designated storage point that undertakes direct purchase from farmers. The corn purchased and put into storage must be domestic corn produced in 2014 and comply with domestic quality standards such as national standards. Specific quality standards are implemented in accordance with the national corn standard (GB1353-2009).
