Foreword

GB/T 12529 "oil industry - Graphic symbols and codes" is divided into five parts.

--- Part 1. Common part;

--- Part 2. Milling Industry;

--- Part 3. milling industry;

--- Part 4. Oil Industry;

--- Part 5. Storage industry. This section is GB/T Part of 412,529. This part is GB/T 12529.4-1990 "oil industry - Graphic symbols and oil industry," the amendment. This portion of the GB/T 12529.4-1990 main technical differences are as follows:

--- Original standard peel isolated broken (Y101 ~ Y104), flaking steaming and roasting (Y201 ~ Y207), oil extraction (Y301 ~ Y305) were combined, All classified pretreated oil extraction (Y101 ~ Y133);

--- Increased vertical dryer, 39 soybean quenching tower, soybean hulls kernel separator and the like;

--- Canceled 15 plane rotating screen, the hydrogenation reaction tank, Dawson gases;

--- Standard part of the original specification terminology, such as. "steaming machine" to "steam off", etc. Since the implementation date of this section, the place of GB/T 12529.4-1990. This part is proposed by the National Food Authority. This part of the National Grain and Oil Standardization Technical Committee centralized. This section is drafted. State Grain Reserve Xi'an Oil Research and Design Institute, Wuhan Polytechnic University. The main drafters of this section. Bai Yun love, Ran Ping, Duxuan Li, Zheng, Lin Guoxiang, closed source, Linzheng Jun. This part of the standard replaces the previous editions are.

1 Scope

GB/T 12529.4-2008 is the Chinese national standard on graphic symbols and codes for grain and oils industry - part 4: oils and fats industry, in the field of food technology. 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 4 November 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 20 January 2009.

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 section GB/T 12529 specifies the graphic symbols of industrial oil preparation process flow diagram used. This section applies to grain and oil industry production, research, design, education and other related fields. This section does not specify a process flow diagram for the project is generally not expressed and has been included in GB/T 12529.1 of the project.
