Cake, mixers

Cake mixers are usually of the planetary type (Figure 3). In some ways they are a scaled up version of a domestic table mixer. Some cake mixing involves whipping eggs so there is a requirement to beat at high speed... 

Weigh 2.5 or 5 g of crop matrix into a blending vessel. Fortify samples at this point with the appropriate analytical standards. Allow the solvent to evaporate. Add 100 mL of acetone-water (4 1, v/v) and blend the mixture using an Omni mixer equipped with a macro generator for 5 min at 6000-7000 rpm. Filter the sample through a Whatman 934 AFI glass-fiber filter paper on a Buchner funnel/vacuum flask setup. Rinse the blending cup and filter cake with 100 mL of acetone. Transfer the filtrate into a 200-mL TurboVap vessel.

Batters. A few biscuits are made from a dough so soft that it is really a batter. These products sometimes contain eggs. As these products are nearly cakes they are made in a cake-type mixer with a high sheer rate to incorporate air. 

An alternate procedure for 100 to 200g batches used a Cradle-Roll Mixer. This device consisted of a half-barrel type container constructed of wood and lined with an electrical conductive material. A plastic roll was allowed to move over the ingredients by remote control action. The roll action prevented caking of the mixt but had no adverse effect on particle size of the ingredients. The period of time to obtn an intimate mixt was approx 15 mins... 

Glean a standing mixer according to the directions in "Golden Rules and Tips for Cakes and Cupcakes (page 2, ])- Place the egg whites in the mixing bowl. 

Target These stores carry simple baking supplies such as pans, baking sheets, measuring cups, bowls, zesters, mixers, spatulas, whisks, etc. They don t specialize in cake decorating, but they will cover your basic needs. 

The second mixer is charged with the spent leaf from the first mixer and with the filtrate from the previous batch in the third mixer. The leaf is extracted for several more hours, and the contents of the mixer are then discharged to a second filter. The filtrate, which contains 1% of the leaf fed to the second mixer, is pumped to the same holding tank that received the filtrate from the first mixer, and the solid cake—spent leaf and entrained liquid—is sent to the third mixer. The entrained liquid mass is 15% of the mass of liquid charged to the second mixer. 

The contents of the filtrate holding tank are filtered to remove the carried-over spent leaf, and the wet cake is pressed to recover entrained liquid, which is combined with the filtrate. A negligible amount of liquid remmns in the wet cake. The filtrate, which contains D, E, and W, is pumped to an extraction unit (another mixer).
