GB/T 16714-2025Continuous-flow grain driers (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 16714-2007 "Continuous Grain Dryers". Compared with GB/T 16714-2007, the main differences are structural adjustments and... Aside from editorial changes, the main technical changes are as follows:

---The terms "grain layer thickness" and "drying period" have been removed (see

3.2 in the.2007 edition);

---The word "Type" has been removed (see

4.1 in the.2007 edition);

---Added model number marking methods and examples (see 4.1);

---Added safety technical requirements for auxiliary equipment of the dryer, electrical safety requirements, and electrical system safety requirements (see 5.7, 5.8, and 5.9);

---The general requirements for dryer parts and auxiliary equipment have been revised, and requirements for biomass pellet hot air furnaces and oil/gas burners have been added. (See 6.1,

5.1 in the.2007 edition);

---Added basic environmental conditions for the unit calorific value of dried rice, wheat, and corn (see 6.2.2);

---The main performance indicators of the dryer have been modified, adding indicators such as the rice cracking rate and the grain temperature at the outlet, while removing indicators related to germination (growing)... Vitality rate indicator (see 6.2.3,

5.2.4 in the.2007 edition);

---The section on "grain layer thickness and grain inlet/outlet mechanisms" has been removed (see section

1 Scope

GB/T 16714-2025 is the Chinese national standard on continuous-flow grain driers, in the field of agriculture. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 31 October 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2026. Classification: ICS 65.060.99, CCS B91. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the model and main parameters, safety requirements, technical requirements, and inspection procedures for continuous grain dryers (hereinafter referred to as "dryers"). The rules, marking, packaging, transportation and storage requirements describe the corresponding test methods. This document applies to continuous grain dryers.
