Introduction
1. Standard Overview
GB/T 35864-2018 Grain Bulk Density Apparatus for Grain and Oil Machinery Inspection specifies the terminology, working principle, classification, main structure, model compilation, technical requirements, test methods and inspection rules of grain bulk density apparatus. It is a professional equipment suitable for measuring grain bulk density.
2. Technical requirements for bulk density instrument
| Technical indicators | Non-self-indicating bulk density instrument | Digital indicating bulk density instrument |
|---|---|---|
| Weighing range (g) | 1000g | ≥3000g |
| Minimum division value | 100g and 1g | 0.1g |
| Operating temperature range | -0℃~40℃ | -0℃~40℃ |
Explanation of professional terms and case application:
Bulk density instrument: used to measure the mass of grain per unit volume, expressed in grams per liter (g/L). For example, in the GB/T 5498 standard, the method for measuring grain bulk density is highly consistent with the technical requirements of this standard.
3. Comparison of the dimensions of the volume cylinder and its main components
| Serial number | Component name | Basic parameters | Specified value |
|---|---|---|---|
| 1 | Volume cylinder | Inner diameter/mm | 88.5±0.05 |
| 1 | Volume cylinder | Volume/mL | 1000±1.5 |
| 2 | Intermediate cylinder | Inner diameter/mm | 79.0±0.1 |
4. Comparison of standard framework and implementation suggestions
This standard is in line with international technical requirements for grain testing equipment and has the following characteristics:
- Unified the terminology definition and measurement method of bulk density apparatus
- Cleared the technical parameter differences of different types of bulk density apparatus
- Detailed the quality requirements of volumetric cylinders and key components
Implementation suggestions:
- Technical improvement direction:It is recommended to use high-precision sensors and automated control technology to improve measurement accuracy and ease of operation.
- Operation training: Develop special operation training manuals for different types of bulk density instruments (non-self-indicating scales and digital indicating scales).
- Maintenance: Regularly check the status of key components (such as volume cylinders, inserts, etc.) to ensure long-term stable operation of the equipment.
5. Future prospects of standards
With the development of intelligent technology, future grain bulk density instruments will evolve in the following directions:
- Automated measurement and data recording
- Wireless data transmission function
- Multi-language interface support
