Product Description

Walnut Oil Mill Plant during the process of Oilseed pretreatment, a series of seed processing equipment are necessary, such as cleaning sieve, crusher, dehuller, flaker, cooker, screw extruder, dryer and oil presses. Some seeds require additional preparation beyond cleaning. Soybeans, for example, are de-hulled, heated, cracked or flaked, and sometimes extruded before entering the press. Equipment used for these types of operations can generally be obtained from most press manufacturers. A producer should identify the oilseeds they need to process in order to determine exactly what equipment will be needed. WorkGroup can always meet your cleaning and pretreatment needs!

All the seed processing equipment are designed to adjust to the different oil seeds and the client exact requirements.we have rich experience of manufacturing and exporting large selection of various seed processing machine and equipment for different using purposes and our clients are very satisfied with our seed processing equipment. We give the best service and we offer the most competitive prices in seed processing filed.

Oil Extraction Workshop of Walnut Oil Mill Plant Craft flow:

solvent steam

→ →

extraction →mixed oil →evaporation’ steam-stripping →crude oil

Extractor types:

Level rotation extractor, loop type extractor, chain extractor

Extraction methods:

Use organic solvent through soaking or spraying contact methods to extract oil from oilseeds.

Advantages of extraction craft:

1.High oil yield, low residual oil in meal;2.Low labor intensity;3.Good working environment;4.Good meal quality.

Negative pressure evaporation helps to improve crude oil quality.

Craft features:

1. Adopting negative pressure evaporation can ensure excellent oil quality;

2. Extraction system is highly adaptable, and can adapt to different raw material ;

3. All equipments are provided with exhaust gas absorption system with excellent absorption effect;

4. Full energy-saving design utilizes heat energy for many times and saves steam consumption;

Oil Refining Workshop of Walnut Oil Mill Plant Craft flow:

crude oil→degumming&dephosphorization→deacidification →drying→decolorization→deodorization→defatting→dewaxing→finished oil.

Refining methods:

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 standard oil.

Advantages of refining craft:

1. After refining the impurity of oil must be less than 0.2% ; 2.Recycling system save power and money; 3.Lower oil waste.

Craft features:

1.Continuous alkali refining shortens contact time between oil and lye,reduces grease saponification,lowers refining consumption,and improves efficiency.

2.Decolorization adopts technology of combining premixing and steam mixing bleaching,which improves bleaching efficiency,saves consumption of bleaching clay,and it’s simple and convenient to operate;and negative pressure state avoids oxygen in the air from contacting with hot oil,thereby ensuring oil product quality,inhibiting acid value to rise again,and lowering peroxide value.

3.Deodorization adopts new type continuous deodorization equipment which is applicable for deacidification and deodorization of plant oil with high acid value and low-resin content,the actual production proves its most obvious advantages are strong deacidification ability,excellent hot bleaching effect,high refining rate,good oil quality and so on.

4.The process has multiple heat exchange,which makes full use of the heat energy system,effectively reduces steam consumption,and also has the advantages of adjustable production process,flexible operation,high automatic degree,environment sanitation and so on.
