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.
