Whenever you want to produce a varied amount of the product you are making, the Recipe Builder enables you to scale the batch size of a recipe. When scaling the batch size, the Recipe Builder preserves the relative proportions among the recipe items and variables being scaled.
The Recipe Builder allows you to scale a recipe's batch size in the Recipe Development window. The first step in scaling a batch is to complete the Standard Batch Size field in the recipe header. The Recipe Builder assigns the batch size value you enter to the #STD_BATCH keyword. The program then uses the specified value to calculate the scaling factor. For more information on the Standard Batch Size field, refer to the section Recipe Header.
After you define the standard batch size, you must define the current batch size of the recipe. You can define this quantity with the Set Batch Size command.
When you select this command the Batch Size dialog box appears. This dialog box contains the Batch Size field. This field allows you to specify a value for the current batch size from 0.000001 to 9,999,999.0.
To set the batch size:
- On the Options menu, click Set Batch Size. The Set Batch Size dialog box appears.
- In the Batch Size field, enter the amount of the product you want to make.
When you select the OK button on the Set Batch Size dialog box, the Recipe Builder assigns the value you entered to the #BATCH keyword and displays it in the Batch Size field of the recipe display area, as the following figure shows. The Recipe Builder also divides #BATCH by #STD_BATCH to compute the scaling factor. The result of this calculation is stored in the #SCALE keyword.
The Recipe Display Area
The next step is to multiply the formula of each recipe item you want to scale by #SCALE. Once this is done, you can scale a batch by changing the current batch size. The following figure shows how to use #SCALE in a recipe.
Scaling a Batch
If you attempt to change the batch size of a recipe item or variable with an overridden formula, the Recipe Builder warns you by displaying a message box with the following text:
There are recipe items with OVERRIDE VALUES
Select the Clear All button to clear all override values or select the Continue button to keep the overrides in effect and set the batch size. To quit without making any changes, select the Cancel button.
