Appendix A
【Appendix to the standard】
Dyeing flash dryer Drying strength test method The moisture content of the material is measured in an oven, and its temperature is not higher than 105°. The thickness is measured by a short-distance display instrument with an error of no more than 1°, and the wind speed is measured by a hot ball anemometer.
A2 Test conditions
: A2.1 The material is edible pressed rice flour with a moisture content of 55%±1% (wet condition) and a particle size of 0.1~03m. A2.2 The amount of test material input is sufficient to ensure that the holding system has sufficient discharge volume, and the discharge volume should be uniform and continuous. A2.3 The operating conditions of the dryer should meet the following requirements: a) Inlet hot air temperature: 120±5% b) Outlet hot air temperature: 70℃±5% e) Wind speed in the drying chamber: 3~3.4ms, A3 test step
From the time the dryer reaches the operating state specified in A2.3, the first sampling is started 30 minutes after the material is discharged from the outlet. Then, sample once every 5 minutes, and measure the sample 3 times within 10mm. Measure the moisture content of the sample and calculate the moisture content of the first outlet. The arithmetic average of the three samples (the moisture content of the material after drying: w:), and the weight of the material (finished product) within 10m is measured at the same time. A4 Drying strength
Hand drying formula (A1) calculation:
Formula: Drying strength, kg (mh);
Weight of the finished material dried within a specified time (on a random basis), kg: Moisture content of the material before drying (wet basis), %; - The average moisture content of the material after drying (wet basis) %: Mill volume, m
+ drying time,.
