You buy and/or sell grain, so you want to know the value and the quality of your batches! (cf. ISO standards, NF V036- 777).
To this end, you need to sample and to analyze the batches you receive or ship.
Sampling standards respond to the specifications of European and International sales contracts. To assess the conformity of a batch, it is essential for the analysis to work on a sample which is representative of the batch being examined; this explains the importance of the number of sample pick-ups (sub-samples) and the area covered by the sampling probe (cf. ISO standard EN NF 24333 (2010-02)). TPLG’s grain samplers are there to help you accomplish this task and to improve your results. Any analysis and any interpretation of its results are vain if the sample itself is not representative of the batch from which it originates.
3 major aspects of the sampling operation:
Sample intake - choose among several sampler designs to meet your objectives
Homogenization - several types of receiver stations accommodate your needs («Cycloburo», cyclone with blending auger, etc.)
Size reduction - different tools are available for you at TPLG (sample dividers etc.)
2 modes of sample constitution:
- direct vacuum intake through monotube probe
- core-sampling through twin-walled probe with vacuum grain transport Whatever the means you choose, the accuracy of the sampling operation increases with the number of sub-samples taken throughout the entire height of the grain load in the trailer cf.
The task of taking the samples should be assigned to trained personnel only, who will make optimal use of the TPLG sampling machines (automation, positioning of the probe, etc.) and who are aware of the importance of the process (number of sub-samples, determining the sampling pattern).
The future is definitely geared toward consistent requirements to provide a more representative sample of static batches of bulk material!
TPLG support you in that direction! And COBRA is one of our solutions to meet the specifications of the international standards in bulk sampling in the best possible way.
Indeed, Cobra is the only sampler that covers the entire area of the trailer in a fast and simple manner. TPLG also propose various kinds of receiver stations, among which you will find cyclones with blending augers and sample dividers.
SARA offers an integral automated solution (reducing the risk of errors due to human intervention, and saving time) designed to automatically distribute the incoming samples to different analyzers, bagging machines for specimen retention sample, containers for manual processing operations, recirculation of the residual sample material back to the vehicle, and so forth.
Sample recirculation is an operation that should not be neglected. Although the option may be a non negligible investment at first, it will in fact soon pay off, as you will no longer waste the excess sample material (amounting to a considerable sum every month), nor will you have to monopolize manpower for some laborious and costly handling operation.
