rice bran pretreatment equipment for rice bran oil processing

Safety:

1. we using auto welding machine to make the reactor,which can guarantee the quality of welding seam,avoid cracking and has a long life for about 8 years.

2. professional heating treatment and x-ray detection chamber for welding seam . 

                              3. vacuum system to prevent oil gas be back to reactor causing accident.

4. with professional thermometer , profession pressure gauge and safety valve.

Environment friendly:
1.de-dusting system to prevent gas and dust from coal burning 

2.the exhaust gas will be recycled for heating reactor ,no gas pollution

3.well sealing on every junction parts to prevent gas leak,no smelly

Longer life :
 Using Q345R special steel plate ,welding seam with auto welding an will get heating treatment and x-ray detection to extend the life of reactor to the most extend, and the life will 8 years

Energy saving:
1. well sealing for heating system ,no gas leak and saving fuel. 

2. the exhaust gas will be recycled for reactor heating.

Introduction of rice bran pretreatment equipment :

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, dehulling, separating, drying, crushing, softening, germ pressing, steaming, roasting and prepressing sections and so on.

1. Cleaning

1).According to different particle size between oilseeds and impurities,remove big and small impurities from oilseeds with vibrating screen.

2). Stones removal. According to different specific gravity and suspended velocity between oilseeds and stones, stones fall down and oilseeds suspend under the action of air flow to separate stones from oilseeds.

3). Magnetic selection. It uses magnet to remove metal impurities from oilseeds. Strong and uniform magnetism attract metals automaically and remove metals to prevent oilseeds carrying stones away, attracted metals by permanent magnet fall down automatically when metals reach non-magnetic area.

4). Remove impurities whose size is similiar to oilseeds according to different mechanical performance between oilseeds and clods, crush clods and then separate them through screen selection or wind selection.

2. Husking

Adopt wind selection and screen selection methods to separate husks from kernels. 

3. Crushing

Before flaking, crush big oilseeds into smaller pieces to increase superficial area, beneficial for transfering softening temperature and moisture, improve softening efficiency.

4. Softening

Adjust moisture and temperature of oilseeds to improve their plastivity and reach required flaking condition.

5. Flaking

Roll oilseeds from pellets to thin flakes through mechanical method.

6.Cooking

Steam and cook green-pressing to cooked flakes through moist, heating, steaming and cooking to break the cellular structure so as to improve pressing oil yield and improve quality of oil and cake or meal.

7.Pre-pressing

For oilseeds with high oil content, it needs pre-pressing to press part of oil firstly and then extract residual oil in cake through solvent extraction method.

Raw materials of oil pretreatment equipment involved: soybean, peanut, rapeseed, cottonseed, sunflower seeds, palm nuts, linseed, tea seed, corn embryo, rice bran, oil seeds, etc.

Craft features of rice bran pretreatment equipment :

1.Create good production enviroment

2.Minimize the total fat loss, increase oil yield and output and improve the quality of oil and cake&meal.

3.Comprehensively utilize impurities and offal.

4.Perfectly match extraction production line, design different production processes according to different materials.
