Random sampling system for granular materials

Abstract

The invention discloses a random sampling system for granular materials. The random sampling system comprises a random sampler, a sample conveying device and an equant sample divider, wherein the random sampler is arranged on a necessary channel for a material during unloading and is used for quantitatively extracting a sample according to a set frequency in the unloading process of a whole vehicle; the sample conveying device is used for conveying samples collected by the random sampler to the equant sample divider; the equant sample divider is used for further equally dividing the collectedsamples into a plurality of parts, and one part is taken as an inspection sample. Therefore, the random sampling system for granular materials can be used for random sampling continuously in the wholematerial unloading process, and the sample is equally divided again at the tail end, so that the consistency of the obtained sample and the whole material is improved, the condition of the whole material can be better represented, the phenomena of non-uniform sampling quantity, poor representativeness and artificial counterfeiting are avoided, and the material sampling is more reasonable, more comprehensive and more scientific.

Description

technical field [0001] The invention relates to the field of procurement sampling of large granaries, in particular to a random sampling system for granular materials. Background technique [0002] Food processing enterprises need a large amount of granular raw materials, especially large-scale food processing enterprises. Raw materials are purchased in batches, with each batch ranging from tens to hundreds of tons. In order to test the quality of each batch of raw materials, traditional raw material procurement, such as Raw rice is purchased in woven bags for freight, drill rod sampling, manual loading and unloading of trucks, manual stacking and storage, manual bag breaking and feeding, raw rice has hidden dangers of plasticizers, labor costs remain high, labor efficiency is low, and the sampling process is traditional , Unscientific, prone to fraud. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention pro...
