Mustard Screw Oil Press 

The whole mustard screw oil press machine contains three workshops: mustard pretreatment workshop, mustard oil extraction workshop and mustard oil refining workshop. 

1. Craft flow for mustard pretreatment workshop

Mustard → magnetic box → cleaning → crushing and flaking roll → plate dryer → to extraction workshop

Main Equipments: 

1. Mustard: Mustard is a tranditional oilseed. It can be made to normal mustard oil and flavor mustard oil. It is popular in many countries.

2. Magnetic box: Clearing the iron impurity which might be in the peanut. The iron impurity will 

be harmful to the following machines, so we need take the iron impurities out. 

3. Cleaning: This parts have different size cleaning sieves to clean the different impurities. After going 

through this part, most of the impurities are moved from peanut.

4. Crushing and Flaking roll: The size of peanut is big, so it's devided into small piece. Then it's made to thin cake for pressing.

5. Plate dryer: Before entering the solvent extractor, the water content must be about 10%, so the dryer is used to adjust the water content.

extractor → mixed oil → 1st and 2nd evaporation  → stripping tower → crude mustard oil

          Wet meal → DTDC toaster → cake

Main Equipments:

1. Solvent pumps: continuously spray solvent to the rotary-typr extractor.

2. Roary extractor: spray and soak the cake with solvent so that oil fats can be dissolved in solvent 

(form miscella). After processing, you can get wet meal and miscella (mixed oil).

3. DTDC: used to separate the solvent from the wet meal.

4. Miscella tank 1st: pump the miscella ( oil with solvent) into the miscella 1st, then add 10% saline water to it. The phospholipid and impurities in the miscella will react with the saline water, at last the reactant 

 precipitate, reaching the goal of purifying.

5. Miscella tank 2nd: the purified miscella will be pumped into it.

6. Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to 

condenser for recycling.

7. Condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.
