PRECISION ROAST / COFFEE ROASTERS / BATCH CAPACITY CLASS
COFFEE ROASTERS3 KG
An entry-level commercial size for a small roastery.
Three kilograms is a common starting point for regular production: batches are large enough for retail and subscriptions, while allowing a varied range without large stocks of roasted coffee.

01/quick verdict
Choose 3 kg for a measured start and a flexible product range. If your sales plan calls for more than 20–30 kg per day or wholesale demand is growing quickly, compare 5 kg models in advance.
wholesale orders quickly increase the required cycle count
separate time must be allocated to packaging
scaling a roast profile to 5 kg requires adjustment
03/assessing the choice
From calculations to technical requirements
01
Actual output
Rated batch capacity is not the same as roasted coffee output. Account for actual batch load, weight loss, roast duration, cooling, and pauses between varieties.
Average batch load
roasted coffee yield
cycles within available working hours
time allocated to reprocessing and quality checks
02
Organizing the workflow
Plan the movement of coffee from storage to the roaster, then through resting, filling, and finished-goods storage. Overlapping hot equipment and clean packaging areas increases the risk of errors.

03
What to check on a specific model
Compare the batch-load range, airflow controls, cooling speed, cleaning access, and local service. Without these factors, the purchase price alone is a poor guide to ownership costs.

Dongyi Commercial 3kg Coffee Roaster
DONGYI · DY-3
Batch
0.2–3.5 kg; stated batch capacity 300–3500 g
Heating
LPG / natural gas / electric; half hot air and half direct fire
It depends on the roast profile and batch load. For example, 8 cycles at 2.6 kg process 20.8 kg of green coffee before weight loss. This is a calculation, not a model specification.
Do I need a separate cooler?+
If cooling is built in, assess its speed with a full working batch. A separate cooler is needed only if the specific production-line design requires one.
For rapid growth, should I choose 3 kg or 5 kg?+
Compare steady demand, the number of shifts, and the cost of unused capacity. With confirmed wholesale demand, a 5 kg roaster often reduces labor requirements.
Ready to check the entire configuration?
Calculate the required output, then plan the roaster together with the premises, cooling, and packaging.
