Introduction

Analysis of the core content of the standard

This standard specifies the technical framework for wet heat treatment for quarantine pests that may be carried in grain processing by-products (such as bean skins, wheat bran, etc.):

Technical elements	Key requirements	Supervision points
Treatment facilities	Must be equipped with six types of core equipment, including temperature and humidity sensors and automatic control systems	Annual measurement verification + password lock function
Process parameters	Temperature ≥ 85℃, humidity ≥ 80%, for 5 minutes (taking TCK as an example)	Temperature deviation of the discharge port ≤ 1℃
Epidemic prevention system	Independent workshop + 700 mesh filtration system is required for the processing of infected wheat	Video surveillance retention ≥ 3 months

Technological evolution analysis

Compared with traditional chemical treatment, the wet heat treatment technology adopted in this standard has three major breakthroughs:

Energy efficiency improvement: Steam latent heat utilization rate is increased by more than 40%

Broad-spectrum inactivation: Covers 34 kinds of weed seeds and 5 types of pathogenic fungi

Environmental advantages: Achieves zero pollutant emissions

Typical Application Case

When processing imported wheat containing TCK at a certain port, the spore inactivation rate reached 99.98% by maintaining 87°C/83% humidity for 6 minutes using a heat-insulating and moisture-retaining tank, which reduced the treatment time by 60% compared to the original dry heat method.

Implementation Recommendations

Equipment Selection: Prioritize an automatic recording system with IoT functionality

Parameter Optimization: Dynamically adjust the steam injection rate based on the moisture content of the material

Staff Training: Focus on mastering the differential parameters of the five types of pathogens in Appendix A
