6 Test method
6.1 After each single machine is rotated, determine the main dynamics, check the compatibility, and debug the system before operation. 6.2 The strength of the dryer is tested in reverse according to the provisions of Appendix A, and the results meet the requirements of 5.1.1. 6. The dryer is within the range selected by the hospital and meets the drying requirements of other materials. According to the requirements of the material drying process in the production case, the dryer is tested on site to test the degree to which the dryer meets the user's requirements for the drying effect of the material (it can be evaluated according to standards, agreements or contracts! 6.4 In the dryer gear test, the manufacturer conducts the test at the test point established by the user and submits the report. The result meets the requirements of 5.5.7 Inspection Rules
7. The dryer must pass the inspection of the product inspection department of the manufacturer and be accompanied by a product quality certificate before it can be shipped! 7.2 The inspection of the dryer is divided into factory inspection and model modification inspection. 7.2.1 Factory inspection
7.2.1. Each lower end dryer is subject to factory inspection and a no-load running test of no less than 2 hours. 7.2. 1.2 If any of the factory inspection items fails, the product shall be deemed unqualified. 7.1.2 For products that have been assembled, the factory inspection items can be carried out on the installation and commissioning site, and the site inspection results determined by the commissioning personnel can be used as the basis for product change.

(Standard Appendix)
Horizontal fluidized bed dryer for dry strength test method The moisture content of the material is determined by the loss method, measured in an oven, the temperature is not higher than 105°C, and the temperature is determined by a thermometer with an error of no more than 1°C.
A2 Test conditions
42.1 The material is selected as yellow powder with a thickness of 0.17-0.25mm and a moisture content of 3%~5%. A2.2 The fluidized bed is equipped with a material as the bottom material, and the static bed height is: 150mm±5mm. A2.3 The components of the dryer meet the following requirements: a) The empty bed gas velocity of the dryer: 0.8~t.0ml/sh) The air inlet temperature of the dryer drying section: 120℃±2℃: The effective moisture content: 0.3%.
Test method
Prepare the initial moisture content of 3%~5% yellow soda ash, which cannot be determined by mixing (Appendix). After the semi-dryer reaches the working state specified in A2.3 and operates stably for h, take samples from the discharge port every 30m, and the sampling frequency is about 50 seconds: Determine the moisture content of one sample; calculate the arithmetic mean value of three samples (in terms of weight); measure the material feed rate from time to time during the sampling process (in terms of weight).
