Here's a tip for canola farmers in berthing, obviously mixture and qualities - pay attention to the screen.
When the rapeseed deteriorated due to the apparent mixture, or feeling that the level of the impurities is too high, refer in this screen to the buyer were used to determine the degree of contamination - is not material and rapeseed buyer are free.
In assessing the investing of rape, the selection screen of the keys.
In some cases, farmers make more money from rape more points to sell, even if the result is more jetties, but be sure that they have to do the math.
"It may increase the amount of impurities in a sample of rape if they help to improve the quality and value of their products," Mohammad Usman, a specialist in the inspection GSC said in an interview after a workshop classification cereal here organized on December 7, Manitoba canola growers and producers in Manitoba wheat and barley associations.
As part of the Canadian Grain Commission (CGC), rules on the content of impurities, grain companies and inspectors CGC as canola farmer Clean required to determine get the best result possible and accurate assessment docking Mohammad said.
"The most years, most classes 1 and rape that the GCC has found this year by their sample program crop. But it can be exceptional cases where you do not have a number one due to an apparent excess mixture still in the sample, even after normal cleaning.
"There are lots of better quality. The last thing you want is to get a number 1, because the cleaning sequence is not carried out approved by the process of CGC ".
The provision on the official grain of the leaders GCC for classification is "Cleaning for quality improvement" and declared: "If the degree of delivery can be improved by additional cleaning, perform cleaning and add additional material to dockage. Cleaning quality improvement can be made anytime after the cleanup assessment has been completed. After cleaning evaluating the material examined removed after the material and choose your equipment to be deleted. "
The team consists of six round hole sieve of CGC five elongated sieve and winnower Carter approved.
CGC apparent defined material mixture "remaining in the sample after cleaning and is easy of Canola without the use of magnification."
apparent mixture is to be determined with the hand canola sample, the amount of impurities removed was purified. (Mixture obviously included therein as impurities).
The mixture tolerances evident in paragraph 1, 2 and 3 of canola are 1.0, 1.5 and 2.0 percent. With these tolerances, it is important to use the right combination of the screen when docking said Mohammad determine.
The GCC said the inspectors should use the round hole, through the "reasonable rape" while removing a major hardware allows.
The slotted sieve reduces the "inseparable mixture of materials visible in tolerance quality with a minimum loss of canola reasonable tone."
By selecting a screen with round holes in the target, most of the material on the top side is to be separated while it is covered by the rape Mohammad. What's on the screen with round holes is part of docking. If many rape and round holes screen falls through impurity levels was reduced, which is paid to the farmer. To avoid this, the inspector can be a big round hole screen, he said. However, this can increase the mixture.
Dockage is captured on a sieve with round holes is performed in a container. What falls through rape, is mainly lower than materials weed seeds.
The sample - about 250 g to time - is then poured to move in a gap screen from left to right 30 times through a sieve effect. The total distance from left to right is 20 cm, or about eight inches. The fine material falls through in a separate container and impurities is maintained.
The level of contamination is kept separate facilitates screen sizes try later when rape demoted or if other adjustments are necessary.
Now canola "projected" is firmly placed in a wind sifter machine Carter with the parameters of the CGC. Brain removed remain all major materials and recorded with the dockage through the sieve with round holes added.
Material is removed from the suction unit Carter placed in a container and counted as on docking.
Now, the purified material is divided into portions of at least five grams and not more than 50th
This inspector hand dials the party, the apparent mixture as a cow wrinkles, goosefoot, bedstraw, wild, ball and amaranth seeds.
The mixture was weighed, and the percentage was calculated.
When the mixture is a higher quality of tolerances, the auditor should consider greater use mixing to reduce and improve quality split screen.
Assuming that the mixture 1.5 percent, rape a no. 2. The inspector made a slotted screen 028 could have used the smallest option. With more slotted screen - 0040 - leave plenty of material fall through to reduce the mixture.
Assuming that the mixture is reduced to 0.2 percent, hold, is about 1 degree, but increased the level of impurities. With slotted screen 0035, the mixture may rise to 0.8 percent. It is even less than one percent, so that the number one is good, and it's a little less impurities.
"This is an example of what the inspector has on the evaluation of rape in the degree of contamination think," Mohammad said. "The point I am making, if at 0.040 slotted screen 028, there are other screens directly in the center go, can be used (0.032, 0.035 and 0.038)," Mohammad said. "If you choose once the 0040 division that actually reduced its remarkable percentage well below tolerance combines its quality at number one to improve, but maybe your higher than it should actually be investing."
You can some space for other settings. For example, one can use a sieve with slots instead of 0,035 to reduce the mixture while achieving better quality and the recognition rate help producers said lower.
