[0023] The present invention is further stated below:
[0024] The industrial sodium nitrite product of the present invention is granular, and the individual shape of each particle is spherical, oval or other approximate shapes, and the particle diameter is preferably controlled at 0.5-3mm, such as its particle diameter being 0.5, 1, 1.5, 2, 2.5, 3 etc. Of course, it can also be slightly larger or smaller than the above range. The moisture content of the above-mentioned granules is ≤0.5% (% on a dry basis), and it is ≤0.5%, that is, any value or interval value controlled within the range of 0-0.5% is acceptable. Of course, it is preferably ≤0.1%, ≤0.05%. The above-mentioned moisture content may also be affected by the processing environment (air humidity in the workshop) and the conditions in the packaging process.
