2) Improving roasting consistency

Establish Roast Rangers in Cropster
Bean moisture changes
Find how to keep changes to minimum

Differences in roast profiles proportional to moisture difference

Stable bean storage environment

Find roasting consequences
Log dailty/weekly moistures of all beans on stock
Ambient temperature and moisture changes
Create protocol minimizing changes in roast
Find how change affects roasting
Get digital thermometer and moisture meter
Roaster overheating

Create correct "Cooling between roasts" protocol

Install Cropster probe

Order Cropster probe for face monitoring

Analyze consequences

Resulting beans seems to be roasted lighter if same roast profile is followed

If more roasts are done in row, roaster starts to overheat itself
Cold roaster inconsistency
Create solution

Create correct heat-up protocol

Find out correct heat-up temperature/time

Testing in progress

Install thermostat for G60

Install and test

Order Thermostat and thermocouples

Simon creating connection diagram

Get specifications for the correct thermostat

Collect data on face temperature and compare to the issue found in taste

Install face thermometer

Install temporary face thermometer

Analyze causes and consequences

If same roast profile is followed, beans will be overroasted

This results in higher percentage of convective heat transfer

First 2-3 roasts are done on cold roaster

1) Improving roasting quality

Advanced cleanliness check for roaster and pack. machine
Find critical points for reducing quality of the product
Create cleaning protocol if none exists
redesign roast profiles for every bean based on physical properties
Create suitable roast profiles
Find patterns of behavior of similar beans
Establish protocol of measuring screen size if possible, bulk density and moisture content.

Create Android app for easy logging

Find overall roasting style
Shorter roasting profiles must be designed correctly to avoid compromising body and sweetness
With slightly shorter roast times we should be able to achieve better flavor developement, better crema on espressos and cleaner taste.

To Be tested

Beans not suitable for shorter times

Pre-blends => Stephens customers

Beans Improved by shorter times

Sumatra

Tanzanian Robusta

Current: Roasts ranging between 17-19 min length, baked flavors are common in some beans, no signs of scorching or tipping, all beans could stand faster ramping

Very often causting vegetable taste with low sweetness and astringency. Common for Centrals and Colombians. Under these conditions these milds are producing unpleasant soury acidity.

Balance Roasters
Find correct airflow for both roasters
Find the right presure for correct ramping and developement on G60 without fluctuations in temperature
Improve handling of the roasters
