30TPD hot selling walnut oil press machine
Oil production line processing flow:
Pretreatment & Pre-pressing ---> Solvent Extraction --->Refining ---> Finished Oil --->Filling / Sale
1. Pretreatment & Pre-pressing Processing
1) Processing Capacity: 10 ~ 5000TPD
2) Processing flow: Cleaning --> Crushing --> Flaking --> Cooking --> Pressing --> Crude oil &Cake
The importance of oil seeds cleaning:
(1) For good storage and transporation
(2) Reduce oil loss, improve oil yield
(3) Improve the quality of oil and cake (meal)
(4) Increase the production capacity of the equipment, reduce equipment wear
(5) Avoid industrial accident, preventing environment pollution
(6) Improve the effect of processing technoloLD
3) Application Range: various oil seeds
4) Brief Introduction:
Design methods of oil pretreatment differ from oilseeds, oil technoloLD, quality index, comprehensive utilization of oil and
the investment amount, etc. According to oil production technoloLD and requirements on product quality, extraction
technoloLD can be classified into Pressing, Pre-Pressing, Hot-Pressing and Cold-Pressing.
2.Solvent Extracting:
Brief processes:
Fresh Solvent--Cake--Extracting--Wet Meal--Desolventising--Meal--Miscella--Evaporating and stripping--Solvent mixture--Condensing and Recovering--Crude Oil--Solvent Recycling--Refining Workshop.
Functions of main parts:
Extracting:To extract the oil in the cake by solvent, the general solvent is 6# extraction solvent oil or commercial hexane.
Desolventising:To remove and recover the solvent in the meal; Dry and cool down the meal at the same time.
Evaporating and stripping:Heating the the miscella by indirect steam, so that can vaporize the solvent and concentrate the miscella.
Solvent recycling: This process is to recover the solvent, decrease solvent coLDuption, keep safety prodution and improve product quality.
3. Crude oil refining process:
(1) Purpose :Oil refining is according to the different usage and requirements , utilizing the physical
methods and chemical processes to get rid of the harmful impurities and needless substance in the
crude oil , getting some standard oil . Our oil refining machine is suitable for refining various crude
vegetable oil, such as sunflower seed oil, tea seed oil, groundnut oil, cottonseed oil, palm oil, rice
bran oil, soybean oil, corn oil and palm oil, etc.
(2)main parts:refining pot , decoloration pot ,deodorization pot , oil pumps and other parts
(3) Advantage:a.After refining the impurity of oil must be less than 0.2% ;
b.Recycling system save power and money ;
c.Lower oil waste.
