大豆預處理車間工藝以及我公司大豆预处理工艺的特点

大豆預處理車間工藝描述:
大豆 ------> 计量------> 磁选------>  除铁------> 清理------> 去石------> 齿辊破碎
软化------>  轧胚------> 膨化------> 冷却干燥------> 浸出

我公司大豆預處理工藝特點
1.全部連續化、機械化操作;並帶有電器聯鎖控制系統;
2.設備布置采用塔樓式結構,物料盡量依靠重力流動,降低動力消耗;
3.膨化工段設計時考慮生産不同比例膨化料和生坯浸出的情況,根據産品的需求隨時調整;
4.生産胚片豆粕時,使用滾筒軟化鍋更加適合壓胚的工藝要求;
5.考慮到現代工業的環保要求,在本車間亦配有較強能力的除塵系統,以滿足生産和環保的要求;
6.在輸送過程中盡可能多地選用刮板輸送機,有效減少了輸送過程料坯的破碎,有利于浸出過程中溶劑對料層的滲透,提浸出效率;
7.我公司還在軋胚工序的後面加上大豆膨化工序,對豆胚進行膨化,以進步破壞油料細胞的結構,大大提升産量,得到受飼料廠家歡迎的膨化粕。

工序描述:
計量工序:采用專用設備,計量稱生産穩定,用于調節流量和計量生産總量,且能達到累計計量、瞬時計量和成本核算的目的,計量准確,精度。
清理工序:采用磁選器去除鐵雜;振動清理篩去除大雜、稭稈等;比重去石機去除石子和磚塊等重雜;除塵系統采用單聯刹克龍以及離心風機進行有效的除塵,以保證車間衛生和清理輕雜。
軟化工序:采用YRHW系列臥式軟化鍋,通過進料絞龍進入軟化轉筒內,隨著轉筒的轉動,物料得到不斷的翻動,由于轉筒內裝有加熱列管,列管內通有蒸汽,因此物料在隨著轉筒不斷翻動的同時,將大豆加熱到50-70℃,使其充分軟化,提大豆原料的塑性,使軋胚機軋出的胚薄而不碎,從而提浸出效果。轉筒帶有進料端、出料端低的傾角,根據物料的軟化情況,通過調速裝置調節轉筒的轉速,可以控制物料在轉筒內的軟化時間,使物料的軟化效果達到佳狀態。
軋胚工序:采用液壓緊輥軋胚機,較好的破壞油料細胞組織,以保證軋坯片薄而均勻,有韌性,粉末度小。

Soybean pretreatment process description:
Soybean→metering→magnetic separation→deironing→cleaning→stone removing →gear roller crushing→softening→flaking→extrusion→cooling&drying→extraction

Characteristics of our soybean pretreatment process:
1. Full continuous and mechanized operation, and with electrical interlocking control system.
2. The equipment layout is in tower structure, and the material flow by relying on gravity to reduce reducing power consumption.
3. In extrusion process, consider producing extrusion material in different proportions and raw germ extraction, and adjust it at any time according to product requirements.
4. When producing soybean germ meal, the roller softening pot can better meet the flaking technical requirements.
5. Take into consideration the environmental requirements in modern industry. The workshop is also equipped with the dedusting system with high performance, so as to meet the requirements of production and environmental protection.
6. Select scraper conveyor as much as possible, which can effectively reduce raw material crushing, improve solvent permeation into the material layer, and increase the extraction efficiency.
7. Our company adds soybean extrusion process after flaking process, to extrude the soybean germ, further destroy oil material cell, improve the productivity greatly and get the extruded meal that is well-received by feed manufacturers.

Process description:
Metering process: with special equipment, the stable measuring scale is used to regulate the flow and measure total production. Moreover, it can achieve accumulated measurement, transient measurement and cost accounting, with accurate measurement and high precision.
Cleaning process: use magnetic selector to remove iron impurity, vibration cleaning sieve to remove straw, and gravity stoner to remove stones, bricks and other impurities. The dedusting system uses single union cyclone and centrifugal fan to remove dust effectively, so as to to ensure workshop hygiene and clear light impurities.
Softening process: with YPHW series horizontal softening pot, material enters softening drum through feeding auger, and turns over with the rotating drum. The rotating drum is equipped with heating tube, and there is steam in the tube. When material turns over continuously with the rotating drum, soy is heated to 50-70℃ and is fully softened, which can improve soy plasticity, make germ flake thin and burly and improve extraction effect. In addition, the rotating drum has the inclination of high feed end and low discharge end. According to material softening conditions, regulate the rotating speed of drum to control the softening time of material in the rotating drum, so as to achieve the best softening effect.
Flaking process: our hydraulic compact roller flaker can better damage the oil material cell to ensure thin and uniform flake, with high toughness and small powder.
