When steaming and cookery, identical size blanks is pressing unceasingly in oil pressing machine to urge copra oil. Salt virgin bore section of the tapered finish to export oil in most cases in accordance with the uniform discharge graph decreasing. In general, the processed of copra oil pressing machine obtained cake residue was seven-membered.

Step three: copra oil Pressing
Efficient operation of the screw oil pressing machine wants steamed coconut deep-fried and quenched billet temperature management between ninety one ~ ninety three ℃, ninety one ℃ below the water underneath the conditions of over four wheel drive, copra oil billet lower. whereas ninety three ℃ on top of, the water content of but third underneath conditions of low oil yield from coconut blanks manufactured from dark oil and coke cake on to urge. separate fine particles and precipitation doesn't exceed 100% of the contemporary raw materials so as to avoid speculation within the press when treatment with steam quenched part formation fines.

Step Four: Treatment method when copra oil pressing
Coconut oil obtaining out from screw oil pressing machine flows into screens and oil clarification tank, begin to separate the particles, which can be mixed with the material along into the system, so processed to edible fat per ton of higher clay mixed with ten weight unit of edible fat obtained when filtration. The copra oil is distributed into storage or any process of copra oil hm (cake) into the filter press over when granulation, fabric to animal feed plant.

Subcritical No. 4 Solvent Extraction Production Line

Subcritical extraction technology is a bit different from common used no. 6 solvent oil extraction machine. This advanced subcritical fluid extraction is mainly used to extract oil from those of precious oilseeds such as tomato seed, grape seed, watermelon seed, pumpkin seed, walnut kernel etc.

Oil extraction technology pioneered in 1855 by E.Deiss (Franch), and formed a production scale industry in 1870. The application of oil extraction sufficiently improves utilization of plant oil. There are at least 12 kinds of solvent used for extraction: e.g., carbon disulfide; crude hydrocarbon fuel; ethanol; method of water; petroleum hydrocarbons; benzene; halogenated hydrocarbons; isopropanol; formaldehyde, furfural; one, acetone, methyl ethyl ketone, supercritical carbon dioxide; mixed solvent etc.

The domestic edible oil extraction mainly uses 6# solvent, foreigners generally uses industrial hexane, octane or pentane for oil extraction.
4# solvent (the main component of liquefied propane, butane) oil extraction technology is also called subcritical extraction technology. It is a very new oil production technology, which has significant economic and social benefits while comparing with 6# solvent.

Subcritical No.4 solvent extraction featured characteristics:
● Normal temperature extraction, low temperature desolventization
● No destroy of active substance and plant protein of oil materials in oil extraction
● Applicable for precious oil and vegetal protein extraction
● Low vapor consumption, reduces 80% coal consumption in oil processing
● Low cost, big scale, and low environmental protection

Subcritical 4# solvent oil extraction principle:

4# solvent is purified from liquefied petroleum gas, consisting of propane, butane, boiling point is below 0 ℃. Oil extraction machine is processing under pressure (0.1-0.7Mpa liquid state) and room temperature to realize normal temperature oil extraction. Solvent in extracted meal and crude oil is removed at low temperature and vacuum. Solvent is cycled use after liquefaction.

Crude oil quality after subcritical 4# solvent extraction:
4# solvent has low boiling point, pure ingredients, and low residual solvent after extraction, low extraction temperature, good selection, less pigment, phospholipids and other impurities. No. solvent subcritical oil extraction method is an efficient method to maintain original flavor of oil, and keep maintain protein content from being changed caused by high temperature extraction and desolvent etc. The normal temperature subcritical solvent extraction machine is highly recommend choice for extraction of treasured oilseed materials.

Subcritical Solvent Extraction Technology Introduction

Subcritical solvent extraction adopts advanced designed process of those of precious oilseeds. It realizes high efficiency low temperature desolventization, low solvent residual of less than 1% and high oil content. This is complete different extraction methods from formal used 6# solvent. No. 4 solvent (main component of liquefied propane and butane) oil extraction technology is also called subcritical extraction technology. No. 4 solvent oil extraction technology is a complete new oil production technology. It is a somewhat more advanced extraction method than traditional No. 6 solvent oil production line. It has bigger social and economic benefits than No. 6 solvent oil extracting method.

Subcritical Solvent Extraction Processing Line

Features of subcritical No. 4 solvent extraction processing line:
● Normal temperature oil extraction and low temperature desolventization. The featured characteristic cannot destroy the active substance and plant protein in oil extraction. It provides convenient condition for precious oilseed extraction and development of plant protein.
● Low steam consumption. Owing to requirement of normal temperature extraction, there is no need of high temperature evaporation. It reduces nearly 80% coal consumption in extraction process. Thus, it reduces the project investment and industry waste emissions.
● Lower cost than supercritical extraction. The advantage of large-scale oil pressing machine plant has caused it a very popular oil extraction method. It has been fully replaced supercritical technology.

Working principle of subcritical solvent extraction processing line:
This is a more simple and environmental protective oil extraction technology than normal used method. No. 4 solvents are purified from lliquefied petroleum gas, consisting of propane, butane, boiling point is below 0 ℃. Extraction is processing under certain pressure (0.1 ~ 0.7Mpa liquid state) and under room temperature, achieving room temperature oil extraction. Solvent in crude oil and meal removes at a low temperature and vacuum state. Solvent cycles use after liquefaction.

Processing Flow of subcritical solvent oil extraction:
● Oil materials enters into extraction tank   
● solvent pump injects 4# solvent into oil extraction tank for oil material immersion
● solvent pump pumps mixed oil to evaporative tank
● connect extraction tank and suction port of compressor in order to gasify solvent residual in meal, enters into compressor. Solvent flows into solvent turnover tank after compressing, condensing and liquefy in condenser for reuse. Meal discharges from extraction system.
● mix oil enters into evaporation system in order to separate crude oil and evaporate 4# solvent. Evaporated solvent is reused after compressing and liquefy, and crude oil discharges from extraction system.

Featured by low boiling point, pure ingredients, low residual solvent, and low leaching temperature, good selection, crude oil after subcritical solvent extraction are always in good oil quality as well as good quality extracting meal. It has low cost spending on electricity, coal and vapor. It is a very popular and environmental protection project acceptable by more and more users worldwide.
