How to make black garlic with a black garlic fermenter?
Black garlic is made by fermenting fresh garlic under controlled temperature and humidity conditions over an extended period. During this process, the garlic cloves gradually turn dark, develop a soft texture, and acquire a mild, sweet, and slightly tangy flavor.
The black garlic fermenter provides a controlled processing environment, helping food manufacturers produce black garlic in batches with more consistent results.
From fresh garlic preparation to finished black garlic, the production process involves several steps. Understanding these steps and the role of the fermentation machine can help businesses improve their black garlic production.


How is black garlic made from fresh garlic?
Black garlic production mainly involves raw material selection, preparation, machine loading, controlled fermentation, and finished product inspection.
Step 1: Select fresh garlic
Choose mature, fresh garlic bulbs without mold, rot, or serious mechanical damage. Garlic with relatively uniform size is preferable because differences in bulb size can affect moisture distribution and fermentation results.
The quality of the raw material directly influences the appearance, texture, and final quality of black garlic.

Step 2: Clean and prepare the garlic
Remove soil, dust, and other impurities from the garlic surface. Sort the bulbs according to size and remove damaged ones.
Depending on the production process, garlic may be processed with its skin intact. Proper preparation helps maintain raw material cleanliness before fermentation.
Step 2: Load garlic into black garlic fermenter
Arrange the prepared garlic bulbs on the black garlic fermentation machine’s trays or racks. Avoid excessive stacking so that heat and humidity can reach the garlic more evenly.
A commercial black garlic making machine usually provides a relatively large processing chamber for batch production.

Step 4: Set temperature and humidity for fermentation
This is the key stage of black garlic production.
The black garlic fermenter maintains the processing environment through its heating and humidity control systems.
During fermentation:
- Temperature control maintains the required heating conditions.
- Humidity control helps regulate moisture inside the chamber.
- The control system manages the processing conditions throughout the fermentation cycle.
Under these conditions, garlic gradually develops its characteristic dark color, soft texture, and sweet flavor. The exact fermentation time depends on the processing parameters and raw materials.
Step 5: Complete fermentation and check black garlic
When the fermentation cycle is complete, remove the garlic from the black garlic fermenter machine and check the finished product.
Well-processed black garlic generally has a dark brown to black interior, a soft and chewy texture, and a sweet, slightly sour taste.
After inspection, the black garlic can be packaged and sold directly or sent for further processing into paste, powder, and other food ingredients.


How does a black garlic fermentation machine work?
A black garlic fermenter machine is designed to provide the controlled environment required for black garlic production. Compared with manually managed fermentation, the machine integrates heating, humidity regulation, and automatic control to simplify batch processing.


What factors affect the quality of black garlic?
Even when using a commercial black garlic fermenter, raw material quality and processing conditions remain important. Several factors can influence the final product.
| Factor | Influence on Black Garlic |
|---|---|
| Fresh garlic quality | Affects the final texture, appearance, and processing results |
| Garlic size | Different sizes may result in different processing rates |
| Fermentation temperature | Influences color development and texture |
| Humidity | Affects moisture retention and softness |
| Fermentation time | Determines the degree of processing |
| Loading arrangement | Affects heat distribution inside the chamber |
