Embodiment 1

[0018] Weigh 50g of potassium tripolyphosphate, 30g of sodium pyrophosphate and 40g of 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 prehydration process.

[0019] Drop into 250kg sodium tripolyphosphate material in fluidized bed, measure through XRD, sodium tripolyphosphate 1 type content is 20%, 2 type content 80% in this material, particle size is controlled at 60-200 order, starts fluidized bed, Spray said 10 liters of phosphate solution, spray speed is 0.4 liters per minute, without heating, control material temperature below 30 degrees, fully mix 30 minutes, can obtain granular prehydrated sodium tripolyphosphate product without drying. Collect the products of 40-100 mesh, as qualified products, the products with the mesh number greater than 20 mesh and the products under 100 mesh continue to enter the next production cycle.

Embodiment 2

[0027] Weigh 20g of potassium tripolyphosphate, 20g of sodium pyrophosphate and 120g of 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 prehydration process.

[0028] Put 250kg of sodium tripolyphosphate material into the high-speed mixer. According to XRD measurement, the content of tripolymer type 1 in the material 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 the Said 25 liters of phosphate solution, the spray rate is 0.4 liters per minute, without heating, the temperature of the control material is below 30 degrees, fully mixed for 30 minutes, and the granular prehydrated sodium tripolyphosphate product can be obtained without drying. Collect the products of 40-100 mesh, as qualified products, the products with the mesh number greater than 20 mesh and the pro...

Embodiment 3

[0032] In this example, potassium tripolyphosphate, sodium pyrophosphate and sodium hexametaphosphate were not added, and 25 liters of water were directly weighed for prehydration. Put 250kg of sodium tripolyphosphate material into the high-speed mixer. According to XRD measurement, the content of tripolymer type 1 in the material is 50%, the content of type 2 is 50%, and the particle size is controlled at 60-200 mesh. Start the high-speed mixer and spray the above-mentioned 25 liters of water, the spraying speed is 0.4 liters per minute, no heating is required, the temperature of the material is controlled below 30 degrees, and the mixture is fully mixed for 30 minutes, and the granular prehydrated sodium tripolyphosphate product can be obtained without drying. Collect the products of 40-100 mesh, as qualified products, the products with the mesh number greater than 20 mesh and the 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

technical field [0001] The invention belongs to the technical field of inorganic compounds containing alkali metals and phosphoric acid, relates to the preparation technology of sodium tripolyphosphate for food, and mainly aims at modifying the commonly used phosphate in the current market to make it more convenient for practical use.
