Why Engineers Don't Write Cookbooks


Chocolate Chip Cookies

1.) 532.35 cm3 gluten

2.) 4.9 cm3 NaHCO3

3.) 4.9 cm3 refined halite

4.) 236 cm3 partially hydrogenated tallow triglyceride

5.) 177.45 cm3 crystalline C12H22O11

6.) 177.45 cm3 unrefined C12H22O11

7.) 4.9 cm3 methyl ether of protocatechnic aldehyde

8.) Two calcium carbonate-encapsulated avian albumen-coated

protein ovoids

9.) 473.2 cm3 theobroma cacao 10.) 236 cm3 de-encapsulated legume

meats (sieve size #10)

To a 2-L jacketed round reactor vessel (reactor #1) with an

overall heat transfer coefficient of about 100 Btu/F-ft2-hr, add

ingredients one, two and three with constant agitation.

In a second 2-L reactor vessel with a radial flow impeller

operating at 100 rpm, add ingredients four, five, six, and seven

until the mixture is homogenous.

To reactor #2, add ingredient eight, followed by three equal

volumes of the homogenous mixture in reactor #1.

Additionally, add ingredient nine and ten slowly, with constant

agitation. Care must be taken at this point in the reaction to

control any temperature rise that may be the result of an

exothermic reaction.

Using a screw extrude attached to a #4 nodulizer, place the

mixture piece-meal on a 316SS sheet (300 x 600 mm).

Heat in a 460K oven for a period of time that is in agreement

with Frank &Johnston's first order rate expression (see JACOS,

21, 55), or until golden brown.

Once the reaction is complete, place the sheet on a 25C heat-

transfer table, allowing the product to come to equilibrium.
