24 | Free-flowing potassium bicarbonate composition | US558411 | 1995-11-16 | US5552084A | 1996-09-03 | M. Stephen Lajoie; Robin C. Sargent |
This invention provides a process for producing a particulate potassium bicarbonate composition which maintains its free-flow properties when stored under ambient temperature and relative humidity conditions. In the process, particulate potassium bicarbonate is blended with fine grain alkaline earth metal oxide, and the oxide is microdispersed on the surface of the particles. The oxide reacts with moisture and carbon dioxide to form an adherent physically-bonded coating of alkaline earth metal carbonate on the surface of the potassium bicarbonate particles. The altered particle surface prevents agglomeration of the potassium bicarbonate particles. | ||||||

A method for producing alkali metal polysilicates is disclosed. Polysilicates, produced by hydrothermally reacting an aqueous dispersion of finely divided silica and an alkali metal hydroxide are spray dried and the solid product is fractured and pulverized. The fractured mass is then pelletized employing the solubility of the polysilicates to form a free-flowing product having a continuous, even surface. Pelletization may be effected with or without the use of water and/or binders.

PROBLEM TO BE SOLVED: To provide a manufacturing method and a wrapping method for sodium hydrogencarbonate (sodium bicarbonate) crystal particles having low caking properties, needing no addition of an anticaking agent, and suitable for the fields of food, medicines, and bath salts. SOLUTION: The potassium concentration in sodium hydrogencarbonate crystals with an average particle size of 50-500 μm is lowered to 50 mass ppm or lower, preferably to as low as possible, and the carbonate ion concentration (in terms of sodium carbonate) in the crystal particles is lowered to 1 mass% or lower. Such crystal particles can be obtained by washing sodium hydrogencarbonate crystals with water or an aqueous sodium hydrogencarbonate solution and drying or can be obtained by lowering the potassium concentration in a mother liquor to 400 mass ppm or lower in manufacturing the sodium hydrogencarbonate crystal particles by causing the particles to settle from the mother liquor. Thus obtained sodium hydrogencarbonate is sealed with a wrapping material with a moisture permeability (according to JIS Z0208) at 40°C of 5 g/m 2/day or lower. COPYRIGHT: (C)2004,JPO | ||||||
