Abstract
Abstract A process is used to increase the rate and quality of dispersion of a vegetable gum in water. The vegetable gum is dry blended with a food grade particulate carrier, such as starch, in a fluidized bed. The mixture of the carrier and the vegetable gum is intermittently sprayed sufficiently to wet the surfaces of the carrier and vegetable gum. During the spraying, the particles become tacky and stick to each other to form agglomerated particles. Between the intermittent spraying, the particles are dried by the air fluidizing the bed. The intermittent spraying and drying is continued until agglomerated vegetable gum/carrier particles are formed having a moisture content below approximately 25% by weight.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
119 words
A process for producing a particle having a vegetable gum component, the particle being characterized by quick dispersion in an aqueous solution, the process comprising: dry blending a food grade particulate carrier and vegetable gum particles to obtain a dry blended mixture; fluidizing the carrier/vegetable gum mixture with a gaseous stream; intermittently spraying the mixture with a liquid spray while the mixture is in a fluidized state causing the surfaces of the particles to become tacky and the particles to stick to each other; permitting the particles to dry between spraying intervals; and continuing spraying and drying of the particles until agglomerated particles are produced having a moisture content of less than 25% by weight of the agglomerated particle.
Claim 2
Dependent Claim
119 words
A process for producing a particle having a vegetable gum component, the particle being characterized by quick dispersion in an aqueous solution, the process comprising: dry blending a food grade particulate carrier and vegetable gum particles to obtain a dry blended mixture; fluidizing the carrier/vegetable gum mixture with a gaseous stream; intermittently spraying the mixture with a liquid spray while the mixture is in a fluidized state causing the surfaces of the particles to become tacky and the particles to stick to each other; permitting the particles to dry between spraying intervals; and continuing spraying and drying of the particles until agglomerated particles are produced having a moisture content of less than 25% by weight of the agglomerated particle.
