Introduction
GB/T 36091-2018 Standard Background and Significance
GB/T 36091-2018 is a national standard of the People's Republic of China, and its official name is "Grain Screening Machines for Grain and Oil Machinery Inspection". The standard was proposed by the State Administration of Grain, and the main drafting units include Chengdu Grain Storage Science Research Institute of Sinograin, Guizhou Grain and Oil Product Quality Supervision and Inspection Station and Zhejiang Bethlehem Instrument Equipment Co., Ltd.
Standard Framework Comparison
| Chapter Number | Content Overview | Related Technical Requirements |
|---|---|---|
| 1 | Scope | Applicable to screening machines for grain and oil inspection, covering term definitions and structural types. |
| 6 | Technical requirements | Material selection: Aluminum materials (such as 1060-HX4 or 1060-O) are recommended, which meet the requirements of GB/T3880.1. Sieve hole design: Round holes, rectangular holes and oblong holes are used, and the arrangement type is U-shaped or Z-shaped. |
| 7 | Testing methods | Including dimensional accuracy measurement, surface roughness evaluation and verticality test. |
Detailed explanation of technical requirements
Sieve hole tolerance control: The tolerance allowable range of rectangular holes and round holes must strictly comply with the provisions of Table 1 and Table 2 to ensure screening accuracy.
Actual Application Case
A grain and oil company purchased a batch of grain screening machines that meet the GB/T 36091-2018 standard for screening soybean impurities. After testing, the sieve hole tolerance of the equipment is within the allowable range, and the surface treatment meets the requirements, which effectively improves the screening efficiency and accuracy.
