GB/T 21163.1-2007Agricultural grain driers -- Determination of drying performance -- Part 1: General (English PDF)

Foreword

GB/T 21163 "agriculture grain dryer drying performance measurement" consists of the following components.

--- Part 1. General;

--- Part 2. Additional procedures and crop - specific requirements.

This part of GB/T 21163 Part 1.

The partial modification of the use of ISO 11520-1:1997 "Determination of drying performance of agricultural grain dryers - Part 1. General" (In English).

This part of ISO 11520-1:1997, compared the content changes as follows.

--- Deleted international standards foreword;

--- Of ISO 11520-1:1997 is referenced in ISO 11520-2:2001, it has been adopted as the country with the GB/T 21163.2-2007 instead.

Appendix A of this section is normative appendix, Appendix B, Appendix C, Appendix D, Appendix E is an information appendix.

1 Scope

This section provides a method for the evaluation of continuous and batch-type grain dryer performance. This section provides a method for determining the dryer Experimental tests under steady state conditions, the ability to obtain the required rate of water evaporation. This section also specifies the test Performance (data) to the other input conditions and criteria under environmental conditions conversion method.

This section applies to the determination of continuous and batch-type grain dryer performance.

3 Terms and Definitions

The following terms and definitions apply to this section.

Dry material in a continuous flow mode through without recycling dryer.

After drying in a dryer group of grain drying chamber is completely emptied.

Determination of average atmospheric dry bulb temperature and relative humidity as close to the average dryer main air inlet, but be careful not affect the dryer.

Within a certain period of time determined to be the average relative humidity and air absolute humidity averages and average dry bulb temperature, respectively.

Temperature, pressure and relative humidity conditions on the environmental impact of these test results the dryer is to be amended.
