Overview Instructions Selecting the lots Recording the weight to be milled Milling into a new lot Milling into an existing lot Byproduct weight Confirm milling Milling lots (Video)

Overview 

This article explains how to mill lots. You can record the final green coffee weight once dry-milling is finished. The Milling lot tool automatically deducts the unmilled stock and creates your new green inventory.

You can choose between the following two options:

  1. Creating new lots for the green weight.
  2. Combining the green weight into an existing lot. 

Each lot includes a Grade field that allows you to monitor and categorize the different results from the milling process.

For instance, milling 25 bags of parchment could result in a new lot consisting of 15 bags of high-grade (screen 14+) green coffee. You can also merge 4 bags of low-grade coffee into an existing under-grade lot and 1 bag of defective coffee into a residual lot.

Instructions
 

Selecting the lots

Only the lots that have the following processing steps can be milled (They all have the PP prefix on the ID-Tag): 

  • Parchment
  • Dry-cherry
  • Raw green
 

 

  1. Log in to the online platform C-sar.
  2. Navigate to (Green) Inventory on the main menu bar. 
  3. Locate the PP-lot you would like to mill. 
  4. Navigate to the right side of the page and click on the Mill lot icon. You will be directed to the Mill lots page.
  5. Here you can choose between the following:
    • The resulting milled weight should be used to create a new Green Inventory.
    • The resulting milled weight should be added to the existing Green Inventory.
    • The resulting milled weight should be added to both. 


Recording the weight to be milled

  1. Navigate to the Lots to be milled section on the Mill lots page.
  2. Enter the weight that needs to undergo the milling process.
  3. Click on the arrow to select the entire amount. 

     

Milling into a new lot 

  1. Navigate to the Create new green lot section on the Mill lots page.
  2. Click on +Add new green lot. 
  3. Enter the following details:
    • New lot name
    • Classification
    • Weight 
  4. Click Mill lot to submit. 

Consider creating new lots specifically for your high-grade export-quality coffee.

 


Milling into an existing lot

  1. Navigate to the Add to existing green lot section on the Mill lots page. 
  2. Click on +Add to existing green lot. 
  3. Enter the following details:
    • Destination green lot
    • Weight 
  4. Click Mill lot to submit. 

Consider incorporating lower-quality beans, defective beans, or leftover coffee into existing commercial lots for a more efficient use of resources.

 


Byproduct weight 

At the bottom of the Mill lot page, the remaining weight—the Byproduct weight—is automatically assigned to a new lot with the prefix PY and the state Byproduct.

You can find these listed under Destination lots at the bottom of the original PP Lot Details page.

If there is no remaining byproduct weight after subtracting the total weight of the new/existing lots, then a PY-lot will not be created.

 


Confirm milling

Click the Mill lot button to complete. You will be redirected to the (Green) Inventory overview, where the following changes occur:

  • PP Lot: Disappears if the entire weight was milled.
  • New Lots: Appear with a PG prefix.
  • Existing Lots: Reflect the updated, increased weights.
     

By following the steps below, you can view previously milled lots:

  1. Click on the dropdown next to Customize on the (Green) Inventory overview page.
  2. Enable the option by clicking on the button labeled Include consumed inventory.
  3. The PP-lots will be visible on the Inventory overview page.
