About a grain of Corn

 

 

 

The Processes of the Soybean Pretreating line

 

 

 

 The Machiene Part

 

 

 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.

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.
