Problems solved by technology

[0004] So far, most fertilizer companies have used double caramel pigments to control the appearance of fertilizers in the production process. However, due to the failure to select the appropriate addition point and master the correct addition and metering methods for double caramel pigments, the double caramel pigments Poor solubility in fertilizers, large dosage, high production cost, unstable and uneven color of fertilizers, etc., failed to play a good role in improving the appearance of fertilizers with double caramel pigment

Embodiment 1

[0020] Embodiment 1: in the monoammonium phosphate fertilizer production process,

[0021] (1) First take double caramel pigment according to the mass ratio: water=1:0, mix and stir evenly;

[0022] (2) Transport the double caramel color evenly mixed in step (1) into the slurry and the tank with a plunger mechanical metering pump and fully stir with the monoammonium phosphate slurry to completely dissolve the double caramel color and Mix evenly, and the added double caramel pigment consumes 0.1 kg of double caramel pigment per ton of fertilizer, and is measured by a frequency conversion flowmeter;

[0023] (3) Granulate the monoammonium phosphate slurry mixed with double caramel pigment to obtain the desired color monoammonium phosphate fertilizer. Adjust the amount of double caramel coloring according to the desired shade of monoammonium phosphate appearance.

Embodiment 2

[0024] Embodiment 2: in the monoammonium phosphate fertilizer production process,

[0025] (1) First take double caramel pigment according to the mass ratio: water = 1:0.5, mix and stir evenly;

[0026] (2) Transport the double caramel color evenly mixed in the step (1) to the slurry and the tank with a plunger diaphragm metering pump and fully stir with the monoammonium phosphate slurry to completely dissolve the double caramel color and Mix evenly, the added double caramel pigment consumes 1.0 kg of double caramel pigment per ton of fertilizer, and is measured by a frequency conversion flowmeter;

[0027] (3) Granulate the monoammonium phosphate slurry mixed with double caramel pigment to obtain the desired color monoammonium phosphate fertilizer. Adjust the amount of double caramel coloring according to the desired shade of monoammonium phosphate appearance.

Embodiment 3

[0028] Embodiment 3: in diammonium phosphate fertilizer production process,

[0029] (1) First take double caramel pigment according to the mass ratio: water = 1:0.5, mix and stir evenly;

[0030] (2) Transport the double caramel color evenly mixed in step (1) to the slurry and tank with a micro-single-screw pump and fully stir with the diammonium phosphate slurry to completely dissolve the double caramel color and mix evenly , the added double caramel pigment consumes 3.0 kg of double caramel pigment per ton of fertilizer, which is measured by a frequency conversion flowmeter;

[0031] (3) Granulate the diammonium phosphate slurry mixed with double caramel pigment to obtain the diammonium phosphate fertilizer of the desired color. Adjust the amount of double caramel coloring according to the desired shade of DAP appearance.

Abstract

The invention relates to a method for controlling the fertilizer appearance by double-caramel pigment. In the fertilizer production process, the operation is carried out according to the following steps that (1) firstly, the double-caramel pigment and the water are taken according to a mass ratio being 1:0-0.5 and are mixed and stirred uniformly; (2) the double-caramel pigment uniformly mixed in the first step is conveyed into a slurry neutralizing tank by a plunger type mechanical metering pump, a plunger type diaphragm metering pump or a miniature single screw rod pump to be fully stirred with fertilizer slurry, in addition, the double-caramel pigment is completely dissolved and mixed uniformly, one ton of added double-caramel pigment fertilizer consumes 0.1 to 5.0 kg of double-caramel pigment, and a variable frequency flow meter is used for metering; and (3) the fertilizer slurry mixed with the double-caramel pigment is pelletized, and the fertilizer in the required color is prepared. The method has the advantages that the fertilizer appearance can be conveniently regulated and controlled through the double-caramel pigment, the fertilizer color is uniform and stable, the color mixing of fertilizers cannot occur, in addition, the consumption is low, the cost is low, the biodegradable effect is realized, the environment is favorably protected, the operation is convenient, no pollution, no poison and no public hazard exist, and the like.

Description

technical field [0001] The invention relates to the technical field of fertilizer appearance control, in particular to a method for controlling the appearance of fertilizer by using double caramel pigment. Background technique [0002] At present, some enterprises add dyeing agents to improve the color of fertilizers in the process of producing fertilizers. The dyeing agents are mainly composed of synthetic dyes or pigments and solvents. This kind of dyeing agent is used in fertilizers. The coloring performance is poor, the dosage is large, and the cost is high. , not acid-resistant, not temperature-resistant, easy to change color and fade, and not easy to be degraded, causing pollution to the environment after entering the soil. Therefore, it is necessary to develop and use food coloring, which has good compatibility with the ecological environment, is biodegradable, and is non-polluting and non-toxic to the environment. [0003] Double caramel coloring is a dark brown and...
