Cardamom Grinding for Spice Processing: Low-Temperature Milling Solutions
Cardamom is a high-value spice widely used in food processing, seasoning blends, beverages, and health-related products. Cardamom powder is especially valued for its strong natural aroma, rich flavor, and high essential oil content, which directly affect its market acceptance and economic value. During cardamom grinding, excessive heat can easily damage these sensitive characteristics, leading to aroma loss, color change, and reduced oil content. Therefore, achieving stable and controlled grinding conditions is essential for producing high-quality cardamom powder.
Why Low-Temperature Grinding Matters?
For cardamom and other spices, we recommend low-temperature grinding to better protect their natural properties. By controlling the temperature inside the grinding chamber, low-temperature cardamom grinding helps preserve the original aroma, color, taste, and oiliness of the spice, ensuring consistent quality and higher commercial value. Yinda Machiney has extensive experience in spice milling applications, and we focus on providing practical and reliable grinding solutions.
As a professional grinding equipment supplier, we introduce below two proven cardamom grinding solutions designed for efficient low-temperature milling.
- YDWS Series Low-Temperature Pin Mill for Cardamom Grinding (20–80 Mesh)
The YDWS Series Low-Temperature Pin Mill consists of a YDWS cyclone dust-free pin mill set integrated with an industrial chiller. This configuration enables stable room-temperature milling, effectively protecting the natural aroma, color, and essential oils of spices, while ensuring uniform particle size distribution and consistent output. The system can produce cardamom powder in the 20–80 mesh range, which can be easily adjusted by replacing the inner screen.

Principe de fonctionnement
The YDWS Series Low-Temperature Pin Mill crushes cardamom through the high-speed relative movement of movable and fixed fluted discs, using impact and friction. Crushed material passes through the cyclone separator, where the finished powder is collected, oversized particles are returned for further grinding, and dust is filtered. An industrial chiller, relying on the mill’s high-pressure blower, circulates cooled air to remove heat generated during milling, maintaining low-temperature conditions.
Caractéristiques principales
- Food-Grade Stainless Steel Construction:Made of high-quality food-grade stainless steel with polished surfaces inside and out for hygiene, durability, and easy cleaning.
- Adjustable Fineness:Produces powder in the 20–80 mesh range, easily adjustable by replacing the inner screen to meet different processing requirements.
- Cyclone Discharge System:Ensures smooth and continuous powder collection and efficient, consistent output.
- Efficient Dust Collection:Captures dust effectively, keeping the working environment clean and safe.
- Low-Temperature Grinding:Specifically designed for cardamom and other spices, preserving natural aroma, flavor, and essential oils while ensuring uniform particle size and maximizing product quality and value.
- YDGS Series Low-Temperature Cardamom Grinding Machine(20-60 Mesh)
The YDGS Series Low-Temperature Cardamom Grinding Machine is composed of a YDGS hammer mill combined with an air cooling chiller to achieve low-temperature grinding. This upgraded configuration is specially designed for cardamom, spices, and other heat-sensitive materials.

How the Chiller Integrates with the Hammer Mill
The air chiller is connected to the hammer mill through a sealed ducting connection, forming a closed-loop cooling path within the system. Unlike traditional air cooling systems, our Yinda chiller does not generate airflow independently. Instead, it utilizes the high-pressure blower of the hammer mill system to draw and circulate cooled air throughout the grinding chamber, ensuring stable temperature control without introducing moisture or condensation.
Key Advantages:
- No Risk of Condensation:
As no separate cold airflow is introduced, temperature shock and condensation are avoided, preventing moisture formation during grinding.
- Dry and Stable Grinding Chamber:
By preventing humidity from entering the system, this design reduces material sticking, residue buildup, and caking during high-speed operation. The grinding environment remains dry, clean, and thermally stable, even when processing heat-sensitive or sticky materials such as spices and herbs.
Principe de fonctionnement
- System Configuration:
The machine mainly consists of a feeding port, hammer mill grinding chamber, cyclone discharge system, pulse dust collector, electric control cabinet, and an air cooling chiller. - Grinding Process:
Cardamom is fed into the hammer mill through the feeding port. Inside the grinding chamber, the material is reduced by repeated impact, shear, and friction generated by high-speed rotating hammers. - Material Separation and Discharge:
Driven by centrifugal force and system airflow, the ground material is conveyed to the cyclone separator, where powder is separated from air and continuously discharged, while fine dust is captured by the pulse dust collector. - Low-Temperature Operation:
The air cooling chiller is integrated into the system and relies on the hammer mill’s high-pressure blower to circulate cooled air, helping remove heat generated during grinding and maintain stable low-temperature conditions.
Main Features:
- Efficient Cyclone Discharge:
Tapered cyclone with rotary airlock and pneumatic vibrator enables smooth, continuous discharge. - Reliable Dust Collection:
Pulse-jet cleaned filter bags effectively capture dust, minimizing material loss. - Stable Airflow System:
High-performance centrifugal fan ensures consistent airflow and efficient powder conveying. - Low-Heat Bearing System:
SKF/NSK sealed self-aligning bearings reduce heat generation and ensure long service life. - Hygienic Sealing Design:
Food-grade gaskets with flange-type connections ensure dust-tight and hygienic operation. - Wide Spice Applications:
Suitable for cardamom and all the other spices, with multiple models available for different capacity requirements.
With experience gained from cardamom and spice processing projects, we Yinda Machinery provides practical low-temperature grinding solutions tailored to different spices,capacities, fineness requirements, and application scenarios. We also offer one-stop processing line solutions, supporting stable operation and consistent product quality through proper equipment selection and system configuration.
