Abstract

1 The invention relates to the standardization of hemp raw materials. The aim of the invention is to simplify the method and improve the results obtained in assessing the quality of hemp trusts. Samples of stems formed from segments of the butt, middle and upper parts of the sample at their moisture content not exceeding 7% are subjected to mechanical processing. The shape of the stems sections from the top part of the sample, the alignment at their apical ends is not carried out. The fiber divisibility in the transverse direction and the wearability of the fiber are determined when it is fixed in the clamping device for the top ends. By performing the above analyzes, a quality indicator is determined depending on the fiber yield, as well as on the distance from the butt ends of the stems in the sample to the center of gravity of the sample.

This invention relates to the standardization of cannabis raw materials and can be used in cannabis preprocessing plants to determine the quality of cannabis trusts.

The purpose of the invention is to simplify the method and improve the accuracy of the results obtained in assessing the quality of hemp trusts.

The method is carried out as follows.

From the total mass of the stems a sample is taken (handful). This sample determines the distance from the butt ends of the stems to its center of severity. Depending on this distance, the average length of the handful is determined, which is associated with it by functional dependence. The stalk pattern is divided into approximately three equal parts. Segments of stems from the butt portion of the stems are cut from the first part. From the second part - from the middle part of the stems. From the third part - from the top of the night area. Further, the cut sections, without impersonation, are dried to a moisture content of 7% or less. After drying, the segments of each, a portion of the stems, are hung with the same weight.

Soy is connected, clamped. in a clamping device, weighed together with this device (M,) and subjected to de-icing by mechanical treatment. After the stripping is carried out, the secondary weighting of the stalk segments with the stripped ends together with the clamping device (M) is carried out, then the stripped fiber is cut. The clamping device with the remaining segments of the stems is weighed (M,). The fiber yield index is determined by the formula

Thereafter, the cut fiber strands are analyzed to determine the transverse divisibility of the fiber. Delhi definition

Fiber bridges in the transverse direction are carried out depending on the resistance to the needles that occur when the fibers are combed on the sheath device. As a characteristic that evaluates this force, is the angle of inclination of the fixed platform with the fiber compartment to its original position. Having carried out this analysis, the fiber in the broom (M) is fixed in a clamping device, suspended on a bracket and worn by abrasion, cyclic stretching and alternating bending 5 on a special device. After wear, the fiber is released from the clamp and weighed again (M). Fiber wear rate is determined by the formula

Having determined all the indicators, the quality indicator of the TRONS1I trusts is calculated according to a special relationship.
