Problems solved by technology

However, tobacco coated seeds are approximate spheres with a diameter of 1.6-1.8 mm, while the standard sample pan of the halogen moisture analyzer has a diameter of 90 mm, which is too large for the measurement of coated seeds: if the tobacco seeds occupy the sample pan, it is easy to cause Sample waste, if it is not full, the seeds will be scattered in the sample tray, making it difficult to measure accurately

Embodiment 1

[0053] Example 1 Sample weight selection in the inventive method

[0054] Selected sample 1 is Honghua Dajinyuan, sample 2 is K326, and sample 3 is the seed sample of Cuibi No. 1 variety to carry out the gravimetric experiment of the inventive method. Determine the number of seeds with different weight gradients according to the thousand-grain weight of different seeds, and place them evenly in the center of the standard sample tray to ensure that the seeds are relatively evenly distributed and not squeezed. Use the following steps to measure moisture.

[0055] A. Sample

[0056] First peel the sample plate, put a part of the coated seeds to be tested on the sample plate, and use tweezers to fiddle with the coated seeds so that they are relatively evenly and tightly distributed in the center of the sample plate.

[0057] B. Method

[0058] Establish the determination method, and set the method parameters of the halogen moisture analyzer: the temperature is set at 120°C, th...

Embodiment 2

[0063] Example 2 Measurement and verification of the inventive method

[0064] A. Sample

[0065] First the sample tray of the present invention is peeled, a part of the coated seeds to be tested is placed on the sample tray, and the device is shaken manually for several times at a constant speed, and the coated seeds will gradually enter the concave hole (the size of the seed is equivalent to the size of the concave hole, which can Guaranteed one hole one grain). When there are seeds in the concave holes, tilt the device 30 degrees, and the excess seeds will roll out from the edge of the sample plate, ensuring that 625 seeds remain in the concave holes.

[0066] B. Method

[0067] Establish the determination method, and set the method parameters of the halogen moisture analyzer: the temperature is set at 120°C, the shutdown mode is 3 minutes, and the standard heating program is adopted. The display mode is %MC.

Abstract

The invention provides a sample disc suitable for a halogen moisture meter to measure the moisture content of tobacco coated seeds and a method for measuring the moisture content of the tobacco coatedseeds in the halogen moisture meter by using the sample disc. The sample disc provided by the invention comprises a clamping groove and a base, the clamping groove is a half-surrounded clamping groove, the base is fixed on the clamping groove, and a semispherical concave hole is formed in the base. The sample disc can be used for simply, quickly and accurately sampling tobacco coated seeds; besides, specific parameters and modes of the halogen moisture tester are selected, and the method is simple to operate, short in detection time, accurate in detection result, good in repeatability and small in error.

Description

technical field [0001] The invention belongs to the technical field of tobacco testing, in particular, the invention relates to a method for quickly and conveniently measuring the water content of tobacco coated seeds. Background technique [0002] With the development of the tobacco industry, the application proportion of coated seeds in tobacco seedling cultivation is increasing year by year due to its high stress resistance. According to incomplete statistics, my country's tobacco industry is still using bare seeds for seedling production except in some production areas in Northeast China. Others All production areas use coated pelleted seeds. [0003] In the relevant standards of tobacco coated seeds in my country, it is clearly stipulated that the qualified standard of moisture content is not higher than 3%. Moreover, whether it is tobacco seed production or special monitoring of tobacco seeds, moisture content is one of the key items for judging whether the seeds are q...
