In an ultra-high-shear inline mixer, the high-shear mixing takes place in a single or multiple passes through a rotor–stator array. The mixer is designed to subject the product to higher shear and a larger number of shearing events than a standard inline rotor–stator mixer, producing an exceptionally narrow particle-size distribution.
Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
The various types of food products manufactured by extrusion typically have a high starch content. [1] Directly expanded types include breakfast cereals and corn curls, and are made in high-temperature, low-moisture conditions under high shear. Unexpanded products include pasta, which is produced at intermediate moisture (about 40%) and low ...
The Chorleywood bread process (CBP) is a method of efficient dough production to make yeasted bread quickly, producing a soft, fluffy loaf. Compared to traditional bread-making processes, CBP uses more yeast, added fats, chemicals, and high-speed mixing to allow the dough to be made with lower-protein wheat, and produces bread in a shorter time.
Baking powder is a dry chemical leavening agent, a mixture of a carbonate or bicarbonate and a weak acid. The base and acid are prevented from reacting prematurely by the inclusion of a buffer such as cornstarch. Baking powder is used to increase the volume and lighten the texture of baked goods.
In baking, a farinograph measures specific properties of flour. It was first developed and launched in 1928. [1] The farinograph is a tool used for measuring the shear and viscosity of a mixture of flour and water. The primary units of the farinograph are Brabender Units, an arbitrary unit of measuring the viscosity of a fluid. [2]
Both baking soda and baking powder are leaveners, used in baking to help baked goods rise. Interestingly, baking powder contains baking soda, but not the other way around.
A three roll mill or triple roll mill [1] is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it.
