Example Embodiment

[0017] Example 1

[0018] Weigh 50g potassium tripolyphosphate, 30g sodium pyrophosphate and 40g sodium hexametaphosphate according to the proportion (weight), and then add 10 liters of water to fully dissolve the phosphate in the water to form a uniform solution for the subsequent pre-hydration process.

[0019] Put 250kg of sodium tripolyphosphate material into the fluidized bed. According to XRD measurement, the content of type 1 sodium tripolyphosphate in the material is 20%, and the content of type 2 is 80%. The particle size is controlled at 60-200 mesh. Start the fluidized bed. Spraying the 10 liters of phosphate solution at a spraying rate of 0.4 liters per minute, without heating, controlling the temperature of the material below 30 degrees, mixing thoroughly for 30 minutes, without drying, to obtain a granular pre-hydrated sodium tripolyphosphate product. Collect 40-100 mesh products as qualified products. After crushing with meshes greater than 20 mesh and products under...

Example Embodiment

[0026] Example 2

[0027] Weigh 20g potassium tripolyphosphate, 20g sodium pyrophosphate and 120g sodium hexametaphosphate according to the proportion (weight), and then add 25 liters of water to fully dissolve the phosphate in the water to form a uniform solution for the subsequent pre-hydration process.

[0028] Put 250kg of sodium tripolyphosphate material into the high-speed mixer. According to XRD measurement, the content of trimeric type 1 is 30%, the content of type 2 is 70%, and the particle size is controlled at 60-200 mesh. Start the high-speed mixer and spray For the 25 liters of phosphate solution, the spraying speed is 0.4 liters per minute, without heating, controlling the material temperature below 30 degrees, and mixing thoroughly for 30 minutes without drying to obtain granular pre-hydrated sodium tripolyphosphate products. Collect 40-100 mesh products as qualified products. After crushing with meshes greater than 20 mesh and products under 100 mesh, continue to en...

Example Embodiment

[0031] Example 3

[0032] In this example, potassium tripolyphosphate, sodium pyrophosphate and sodium hexametaphosphate were not added, and 25 liters of water were directly weighed for pre-hydration. Put 250kg of sodium tripolyphosphate material into the high-speed mixer. According to XRD measurement, the content of trimeric 1 type is 50%, type 2 content is 50%, and the particle size is controlled at 60-200 mesh. Start the high-speed mixer and spray the above 25 liters of water, spraying rate of 0.4 liters per minute, no heating, control the temperature of the material below 30 degrees, fully mix for 30 minutes, without drying to obtain granular pre-hydrated sodium tripolyphosphate products. Collect 40-100 mesh products as qualified products. After crushing with meshes greater than 20 mesh and products under 100 mesh, continue to enter the next production cycle.

Abstract

Provided is an anti-caking prehydration sodium tripolyphosphate capable of dissolving in saline water quickly and a preparation method thereof. The preparation method includes: dissolving 0-10 parts by weight of potassium tripolyphosphate, 0-10 parts by weight of sodium pyrophosphate and 0-15 parts by weight of sodium hexametaphosphate into 1000 parts by weight of water; spraying 0.2-15.0 parts by weight of mixed solution onto each 100 parts by weight of sodium tripolyphosphate raw material through a fluidized bed or a high-speed mixer; controlling temperature of materials to be under 30 DEG C and fully mixing for 30 minutes, and obtaining granulated prehydration sodium tripolyphosphate products. Various indexes of the products including contents of sodium tripolyphosphate with main content above 85%, P2O5 and the like are all in accordance with national standard requirements. The prehydration sodium tripolyphosphate can be dissolved in ice saline water quickly (dissolving speed is 20% higher than that of existing sodium tripolyphosphate products), and conditions of caking can not happen. The anti-caking prehydration sodium tripolyphosphate is favorable for being used in food industry.

Description
