EFFECTS OF OPERATING PARAMETERS OF A SCREW PRESS ON SOYA BEAN OIL YIELD
preheating seed moisture content, heating temperature, heating duration, screw press speed, and extraction pressure on soya bean oil yield (Akinoso et al., 2009). However, the effect of screw choke gap which mainly controls the extraction pressure has not been investigated. The aim of this work was to study the effects of screw press factors on
The oil extraction by mechanical pressing is the most common method for continuous treatment of oleaginous seeds without solvent. Different types of presses can be used depending on the purpose (expeller, expander, and twin-screw extruder) and on the capacity range (3 kg h−1 to 150 t day−1). At the laboratory scale, many authors have highlighted the effect of operating parameters (screw
Performance evaluation of continuous screw press for extraction soybean oil
The expected oil yield ranged from 6.30% for 50 o C to 7.56% o for 100 C.Percentage actual oil yield varied between 2.03% for 50 o C to 4.93% for 100 o C, expelling efficiency of the machine
The seeds were prepared to expose the kernel to use for oil extraction. The exposed kernels were used in a screw press and n-hexane techniques to obtain a higher yield of oil. The literature search has shown that the exposed kernels have been used in both screw press and n-hexane techniques to achieve a higher yield of oil (Jahirul et al., 2013).
Development and Performance Evaluation of an Optimized Screw type
Screw oil expeller is a mechanical device which can generate pressure from rotation of feed to expeller screw manually or automatically. Screw press method for oil extraction is a mechanical method for extracting oil from raw materials. Extracted oil from screw pressing are used either as a food product or as an industrial product.
The highest yield of soybean oil was 11.01% when hydraulic pressing conditions such as 50 MPa of pressing pressure and 25 minutes of pressing time at a temperature of 60℃ were applied.
Effect of Pre-Treatments on Mechanical Oil Expression of Soybean Using
Soybeans are relatively hard oil seeds containing less than 20% oil, hence it is hard to express the oil from soybean with a mechanical screw press. The solvent extraction process, in which oil is leached from flakes using hexane, is a popular was to remove/extract oil from soybean.
An innovative design of continuous spiral screw was developed for screw-press oil expeller. The flow velocities in the down channel range from 125 to 175 mm/s through the length of screw from 150
- What is the optimal screw press speed for soya bean oil extraction?
- The following conclusions could be drawn from the results of the study: The screw choke clearance should be equal to or smaller than 1 mm to achieve high soya bean oil extraction efficiency. The optimal screw press speed was found to be 110 rpm for the screw press.
- Does screw speed affect soya bean oil yield?
- Both the screw speed (within the range of 70 to 110 rpm) and choke clearance (within the range of 1 to 3 mm) studied, produced significant differences in soya bean oil yield. Analysis of results showed that the values of the screw press variables for high soya bean oil yield are screw speed of 110 rpm and choke clearance of 1 mm.
- What are the screw press variables for high soya bean oil yield?
- Analysis of results showed that the values of the screw press variables for high soya bean oil yield are screw speed of 110 rpm and choke clearance of 1 mm. The result of this study would be useful for rational design and development of soya bean oil screw press. Keywords: Choke clearance, screw press, screw speed.
- Can a screw press extract soya bean oil?
- Previous studies on soya bean oil extraction using the screw press are very limited. Those studies investigated the effect of preheating seed moisture content, heating temperature, heating duration, screw press speed, and extraction pressure on soya bean oil yield (Akinoso et al., 2009).
