Magnehelic Gauge 

The effect of differential pressure gauge on roasting.

1. can check the exhaust wind speed

The reading of the differential pressure gauge is quite sensitive, and the flow rate of the current detection position can be immediately estimated.

2.can check whether the exhaust path is clean

when use your roaster frequently, the exhaust path gets stuck and reduce the efficiency of exhausting, and excessive dust will affect the flavor of the coffee. The differential pressure gauge can determine whether the machine is exhausted by numerical values.

3. can confirm whether the blower is working properly

Prolonged use of the equipment may cause the system to become hotter and hotter, reducing the efficiency of the blower, resulting in changes in flow rate and pressure, and using the differential pressure gauge for immediate detection and correction at any time.

4. Detect airflow and quantify

Quantify the flow rate indicators, master the key flavors of roasting, and style your own roasting.

5. can check the drum rotation and the turbulent state of the beans

Internal paddle agitation may cause abnormal air pressure in the baking chamber, thus monitoring adjustments.

6.can find out whether the environment has other airflow effects

The difference in air pressure caused by the outdoor roasting weather is adjusted by the differential pressure gauge.

The differential pressure gauge has so many important functions, the ultimate goal of all is to achieve the most stable results of roasting, allowing the roaster to have a more delicate operation in the adjustment of aroma and flavor.Magnehelic Gauge, coffee roaster drum pressure
