Goal for all preparation systems 预处理系统的目标 Best quality flakes for extraction 达到浸出最佳的胚片效果 Consistent feed to extraction 稳定的向浸出进料 Control meal protein by hull removal 脱皮控制粕蛋白
Why a Flake? 胚片的作用 Maximize Exposure to Solvent 最大可能的接触溶剂 Increase surface area 增大表面面积 Minimize Distance from Solvent 到溶剂的距离最短 Thin flakes reduce time needed for diffusion 薄胚片缩短扩散所需的时间 Rupture Cell Wall 裂开细胞壁 Cell walls resist solvent extraction of oil 细胞壁抵御油的溶剂萃取
Maximize Exposure to Solvent 最大可能的接触溶剂 Flakes 胚片
Minimize Distance from Solvent SOLVENT 溶剂 到溶剂的距离最短 0.30 to 0.35 mm SOLVENT 溶剂
Rupture Cell Wall 裂开细胞壁 Breaking Cell Walls 打破细胞壁 Improves oil extractability 提高油的萃取能力 Lb is the Lipid Body 脂质体 CW is the Cell Wall 细胞壁 Pb is the Protein Body 蛋白体

What is needed to make a Flake? 怎么制作胚片? IT S NOT ONLY ABOUT HYDRAULIC PRESSURE 不仅是关于液压 AND HORSEPOWER 和马力
What is needed to make a Flake? 如何做胚片 Clean Soybeans 清理大豆 Condition 调质 Crack Size 破碎 Flake 胚片
Start With Clean Beans 从清理大豆开始 Foreign Material (FM) 杂质 Essentially anything other than soybeans 基本上除了大豆以外的物质都算 Sticks 树枝 Pods 豆荚 Dust and sand 灰, 沙
Start With Clean Beans 从清理大豆开始 Foreign Material (FM) 杂质 Grade is related to FM content. 杂质含量和级别有关 Grade 2 will contain 2% FM. 二级含 2% 的杂质
Start With Clean Beans 从清理大豆开始 It may be obvious, but 可能很明显, 但是 Sand, dust, dirt, and stones do not make good flakes. 沙, 灰尘, 土, 石头无法做出好的胚片 FM promotes: 杂质会导致 Excessive abrasion 过度磨损 Damage to equipment 设备损坏 Reduced plant capacity 减少工厂产能
Whole Bean Screener 全豆筛板 Top: 12 mm Perforated Plate 顶部是 12 毫米的多孔板 Overs to hull grinding 皮粉碎筛上物 Mid: 5 mm Perforated Plate 中间为 5 毫米的冲孔板 Retains large soybeans 保留较大的大豆 Bottom: 14 Mesh Wire 底部为 14 个金属丝网 Retains small soybeans, cracks, germs, etc. 残留较小的大豆, 碎豆, 微生物等等 Field dust and sand are eliminated 清除现场的灰沙
Conditioning Parameters 调质参数 TIME 时间 25-30 minutes 分钟 TEMP 温度 65-68 C H2O 水 10 to 10.5%
Conditioning Time 调质时间 Time is needed for: 时间的作用 Heat transfer inside the soybean 大豆内部的热传输 Moisture migration throughout the soybean 整个大豆的水分移动 TIME TEMP H2O
Conditioning Time 调质时间 Too much time: Promotes enzymatic activity 充足的时间可以促进酶活性 Too little time: Incomplete or inconsistent conditioning 时间太少导致调质的不完整和不持续 TIME 时间 TEMP 温度 H2O 水
Conditioning Time 调质 - 时间 The Best Systems are Flexible 最好的系统是灵活的 Extra capacity for unusually cold or wet soybeans 针对不常见的冻豆, 水分高的大豆, 产能留有余量 But allow some heating sections to remain unused for lower production rates. 生产率低的时候, 一些加热段可以不使用 This allows Residence Time to be a variable YOU CONTROL. 停留时间可以由你来控制 TIME TEMP H2O
Conditioning Temperature 调质 - 温度 Temperature 温度 (65-68 C) Promotes dehulling 促进脱皮 Minimizes fines during cracking 破碎时, 使粉尘最少化 Softens the soybeans for flaking 软化大豆来轧胚 TIME TEMP H2O
Conditioning Moisture 调质 - 水分 Moisture 水分 (10 10.5%) Moisture affects flaking capacity 水分影响轧胚产能 Dry soybeans will lead to brittle flakes and more fines 大豆干燥会导致胚片易碎, 粉尘更多 Drying must be controlled during conditioning 必须在调质时, 控制干燥 TIME TEMP H2O

Other Variables 其他的变量 Crack Size Distribution 粒度分布 Distribution is determined by sieve analysis 筛析决定分布情况 Target is largest size that allows for effective hull removal 考虑到有效脱皮, 目标是粒度最大化 Flaker Operation & Maintenance 轧胚机操作, 维护 Consistent Feed 持续进料 Roll End Maintenance 轧辊端头维护 Flaker Aspiration 轧胚机吸风 Flaking liberates moisture 轧胚释放的水分 Aspiration removes excess surface moisture 吸风去除表面过量的水分
Crack Size Distribution 粒度的分布 Too little moisture results in shattered soybeans. 极少的水分会导致大豆破碎
Crack Size 粒度 When properly conditioned, even large cracks can make thin flakes. 调质正常时, 甚至大的碎豆能做出薄的胚片
