Embodiment 1

[0026] A method of measuring feed uniformity, comprising the steps of:

[0027] (1) Preparation of methyl violet tracer

[0028] (1) Dissolve 10 g of methyl violet in 200 mL of ethanol with a concentration of 95% by volume to prepare a methyl violet solution;

[0029] (2) Mix the methyl violet solution prepared in step (1) with 2000 g of calcium hydrogen phosphate, and stir evenly. The particle size of the calcium hydrogen phosphate is 100 mesh;

[0030] (3) Open and dry the mixture of the methyl violet solution and the tracer carrier in step (2) to evaporate the ethanol solvent to obtain the methyl violet tracer.

[0031] (2) Preparation of feed samples

[0032] After adding 1t of feed into the mixer, add 2kg of methyl violet tracer into the mixer and mix evenly.

[0033] (3) Determination of uniformity

[0034] Use a sampler to collect samples from different positions in the mixer, measure the content of methyl violet in the samples by colorimetry, and use the difference...

Abstract

The invention discloses a method for measuring the homogeneous degree of a fodder. The method comprises the following steps of: dissolving methyl violet by using ethanol with the volume percent concentration being more than 95% to prepare a methyl violet solution; mixing the prepared methyl violet solution with a tracer carrier for uniformly stirring and drying to obtain a methyl violet tracer; then adding the methyl violet tracer to the fodder for preparing a fodder sample; and measuring the homogeneous degree of the fodder sample. By utilizing the method, methyl violet solid does not need to be smashed, the method is environment-friendly, and health threat to operating workers is greatly reduced. Meanwhile, the methyl violet solid does not need to be smashed so that the method for preparing the methyl violet tracer is simple, convenient and easy to operate, investment in pulverizer equipment is also eliminated, and the production cost is reduced. Further more, a sampling device is adopted for sampling when the method is used for detecting the homogeneous degree of the samples, and the samples in different positions of a mixing machine can be sampled so that the condition of the homogeneous degree of the fodder can be truthfully reflected.

Description

technical field [0001] The invention relates to a method for measuring uniformity, in particular to a method for measuring feed uniformity. Background technique [0002] Methyl violet, commonly known as gentian violet and crystal violet, can be used as a disinfectant and preservative, and also as an analytical reagent; but it is moderately toxic, and workers exposed to it can see chronic gastrointestinal diseases, laryngitis, rhinitis, dermatitis and conjunctivitis If swallowed, it can cause gastric ulcer, and prolonged exposure can cause headache, nausea and vomiting. [0003] In the production process of feed, in order to detect the uniformity of feed mixing, the tracer is mixed in the feed when the feed is mixed, and then the feed is sampled, and the feed mixing uniformity is reflected by detecting the tracer content in each sample . Because a small amount of methyl violet exists in the feed, it can disinfect and preserve the feed, and the existing feed tracers usually ...
