The Processes of the Soybean Pretreating line

 The Machiene Parts

Pretreatment and prepressing section is a very important section before extraction.It will directly affect extraction effect.  The set of pretreatment and prepressing equipment includes cleaning,crushing,germ pressing,softening and prepressing sections and so on. 

 Cleaning 

Four parts :

         Screening ,winnowing ,magnetic separation and gravity separation.

 Cleaning index:
  Peanut and soybean the amount of impurity ≤0.1%
  Cottonseed rapeseed sesame seed the amount of impurity≤0.1%
  Peanut soybean cottonseed rapeseed  sesame  the good sesame content in the waste≤1.5%

 The reason for cleaning                

   To improve oil yeild,  get better colour, reduce sediment and improve the meal quality

 Shelling

          The reason why the oil seed need to be husked and kernel husk separation:

           Because the husk will adsorb oil make the oil deep colour and lustre, contain much wax 
           husk methods:friction grind, impact,cut,extrusion

          kernel husk separation:mainly screening and winnowing

Oil seed crack and conditioning 

Cracking:make the oil seed particle size small  under the mechanical forces

Requirement:Uniform particle size, no oil out,no lump,less powder,as to peanut and soybean, make  

into 6-8petals is ok.the length of the pre-pressed cake particle is 6-10 is good generally used the  roll crusher ,hammer crusher, disc huller.

Different methods husk                

Friction grind:make  the oilseed shell broken by friction grind with the rough face, such as the husk of  cottonseed and peanut, that will use disc huller
Impact   make the shell broken Through the collision between the wall or  the plate, Such as centrifugal sheller for shelling sunflower seeds, tea seeds.

 Cut       make the shell broken Through the shearing  of the sharp face , Like a bar huller for cotton seed sheller.   
Extrusion   make the shell broken through pressing of the roll sheller such as the roll sheller for castor bean sheller.

Air impact    make the shell broken through collision between the seed and the shell with high-speed air .

Conditioning:

 Adjusting the moisture and temperature , so that increase the oilseed plasticity, mainly used  in low oil content and low moisture oil.
Two methods in conditioning :

heating watering and heating  anhydrating
Conditioning aiming to:adjusting the moisture and temperature , so that increase the oilseed plasticity,reduce powder when flaking and sticky roller, in order to ensure the quality of the flakes. conditioning can also reduce the vibration of the machine when flaking roll wear, in order to facilitate the flaking operate normally.

Condition temperature:65°Cor so,    time:≥20min

                                                                      Flaking

       It refers to the process that make the oil seed change into flakes from particle.
       The oil sheet after flaking is called flakes , after cooking,it becomes cooked flakes,The fuel cell wall damaged, then shorten the oil discharged from the oil seed away.
  Flaking requirements: the  thickness is uniform, moderate size, no out  oil, less powder, and with a certain degree of mechanical strength.
  Flakes thickness requirements:

    soybean 0.3 mm, cottonseed O.4 mm, rapeseed 0.35 mm, peanut 0.5mm.     
  The powder quantity requirements: the power is not more than 3% through a 20 mesh sieve 
  Flaking roll: three roller,  five roller,single roller, double roller and Hydraulic tight rolling flaking roll.

                             Oil seed flakes extrusion puffing

It refers to the process that make the flakes into puffing particles with the extrusion puffing equipment. After the flakes extrusion and puffing, the oil can be directly made through leaching. This process largely trends to replace direct extraction and pre-processing extraction.
 Extrusion and puffing aim to:
 After the flakes extrusion, bulk density increase, porosity increase, fuel cells and tissues are completely destroyed, enzymes are passivated.
                                         Oil seed flakes cooking 

It refers to the process that the flakes become cooked flakes through the moist, heated,  steam, cooked.

cook aim to make the protein heated,then denatured,and then agglomeration.  Increase the permeability of the cell wall, then the oil is easy to outflow; to gather the small oil drop into big oil drop.Reduce the viscosity of the oil to make it easy to flow 
Cooking  requirements: flakes should be cooked evenly, internal and external are consistent, cooked flakes' moisture, temperature and structured have to meet the oil making requirements.
              wet cooking (moisture:more than 12% water), dry cooking.
