The qualified decolored oil Screw Hydraulic Oil Press machine enters into the spiral plate heat exchanger to recover most of the heat, and Seed crushing machines/seed expeller next goes to high pressure steam heat exchanger to be heated to the process temperature (240-260°C) and then enters the deodorization tower. Shandong Leader Machinery Co.,ltd. The upper layer of combined deodorization tower is the packing structure which Screw Hydraulic Oil Press machine is mainly used to remove the odor producing components such as free fatty acid (FFA); Shandong Leader Machinery Co.,ltd. the bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the peroxide value of the oil to zero. Screw Hydraulic Oil Press machine Oil from the deodorization tower enters into the heat exchanger to recover most of the heat and makes further heat exchange with crude oil, and then is cooled to 80-85°C through the cooler.
Seed crushing machines/seed expeller
Oil production process includes three important parts :oil material pretreatment process,
oil solvent extracting process and oil refining process.
1.Oil material pretreatment process
1. Create a good product environment.
2. Minimize the total fat loss ,increase oil yield and output and improve the quality of oil and cake
meal. 3. Comprehensively utilize impurities and offal.
4. Perfectly match extraction production line ,design different production processing according to
different raw materials.
2.Solvent extraction process
1,Adopting negative pressure evaporation can ensure excellent oil quality
2,Extraction system is highly adaptable and can adapt to different raw materials
3,All equipment is provided with exhaust gas absorption systems with excellent absorption effect
4,Full energy saving design utilizes heat energy for many times and saves steam consumption.
3. Refining process
1. Continuous alkali refining shortens contact time between oil and lye ,reduces grease
saponification ,lowers refining consumption ,and improve efficiency
2. Decolorization adopts the technology of combining premixing and steam mixing bleaching ,
which improves the efficiency ,saves the consumption of bleaching clay , and it is 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 equipments which is applicable for
plant oil deacidification and deodorization of 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 ,steam economization ,good oil quality and the like
4. The process has multiple heat exchange, which makes full use of heat energy system,
effectively reduces steam consumption, and also has the advantages of adjustable production
process,

Shandong Leader Machinery Co.,ltd. Add the required antioxidant and flavor agent, and then cool the oil below 50°C and store it. Screw Hydraulic Oil Press machine Such volatiles as FFA from the deodorizing system are separated by the packing catcher Screw Hydraulic Oil Press machine, and the separated liquid is FFA at low temperature (60-75°C). When the liquid level in the temporary tank is too high, the oil will be sent to the storage tank Seed crushing machines/seed expeller. Our company Shandong Leader Machinery Co.,ltd. has applied the automatic control system Screw Hydraulic Oil Press machine with advancedness, security, reliability into the pretreatment, extraction, refining and fractionation in large oil plants. For Seed crushing machines/seed expeller application in automatic control system, Screw Hydraulic Oil Press machine can control the production in the entire workshop and monitor the operational status of each device by controlling the computer terminals in the room. One person only can operate the entire workshop Screw Hydraulic Oil Press machine, with efficient production management. Seed crushing machines/seed expeller has reduced the production cost greatly and improved the management efficiency.
