Embodiment 50

[0023] Example 50g of potassium dihydrogen phosphate, 5g of potassium stearate and 40g of propylene glycol solution were mixed with 60L of water and stirred evenly. It is added to the recrystallization mother liquor that can separate out 500Kg KCl finished product. After the mother liquor was dried and dried, it was put into a breathable woven bag, placed in an environment with a humidity of 50% at 25°C, and the caking condition was detected after 7 days, 15 days, 30 days and 60 days respectively. After testing, the finished product has no caking phenomenon within one month, and a small amount of caking occurs after 60 days, which has reached the anti-caking effect of industrially produced food-grade KCl.

Embodiment 2

[0025] Weigh 120g of potassium dihydrogen phosphate, 12g of potassium stearate and 60g of propylene glycol solution and mix with 65L of water and stir evenly. It is added to the recrystallization mother liquor that can separate out 600Kg KCl finished product. After the mother liquor is dried and dried, it is packed into a breathable woven bag. Take three 50Kg KCl finished products without additives, add 0.5g potassium ferrocyanide and 1.25g ferric ammonium citrate to two of them, and stir evenly. Place them in an environment at 25° C. and a humidity of 50%, and detect the caking condition after 7 days, 15 days, 30 days and 60 days, respectively. The results are as follows:

[0026]

[0027] The above test shows that the composite anti-caking agent of the present invention is applied in food-grade KCl, and its anti-caking effect is equivalent to that of potassium ferrocyanide, but it is safer to eat because it does not contain cyanide and is colorless ,reliable.

Abstract

The invention discloses an anti-agglomeration agent for food-grade potassium chloride and preparation thereof. The anti-agglomeration agent is prepared from potassium dihydrogen phosphate, potassium stearate, propylene glycol and water in a weight ratio of (1.25-5) to (0.1-0.4) to 1 to (1000-2500). The anti-agglomeration agent is colorless or slightly whitish, and the whiteness of potassium chloride is not changed. Meanwhile, the anti-agglomeration agent does not contain cyanides and is non-toxic and harmless.

Description

technical field [0001] The invention relates to a composite anticaking agent and a preparation method thereof, in particular to a composite anticaking agent used in food-grade potassium chloride and its preparation. Background technique [0002] In order to reduce the possibility of high blood pressure, some potassium chloride is allowed to be added to replace sodium chloride in the current edible salt. However, in the process of storage and transportation of potassium chloride, because the surface is prone to moisture absorption-dissolution-re-precipitation reactions, new crystals are formed between salt particles, resulting in agglomeration, which seriously affects the Its addition effect in edible salt. Therefore, in order to prevent caking, anti-caking agents need to be added during the production process. [0003] At present, potassium ferrocyanide, commonly known as yellow blood salt, is an anticaking agent widely used in salt products at home and abroad, and is allo...
