Palm oil from oil palm pulp by squeezing out of special oil press equipment, and the fruit can make oil is contained in enzymatic hydrolysis of fat decomposition, picked the oil palm fruit if not handled in time,acid value will rise rapidly, seriously affecting the quality of the oil.With the method of high temperature steam to kill yeast damage in the pulp adipose decompose enzyme activity, to slow the progress of the
oil hydrolytic rancidity,This makes the kill yeast after fruit contains more water than before.Because of palm oil distribution in the oil in the oil palm flesh cell tissues, surrounded by cell walls, oil palm fruit have hard outer epidermis,pulp and fiber distribution between the skin and core, to get the palm oil must be torn fruit skin, separate the pulp and the core, dolly pulp tissue, destroy the cell wall.Pulp liquid not only in the oil, when the press will have a lot of water, pulp slurry, and a small amount of fiber with extrusion.Palm oil viscosity value is generally about 4.4, a mixture of various impurities palm oil viscosity will increase.Palm oil press generally USES the hot pressing process, so can reduce the viscosity of oil, separation and flow of oil,To improve the yield efficiency plays an important role.Just squeeze the oil temperature is generally around 60 ° C, or higher.

Oil filter of palm oil extraction machinerypause type selection techniques:
First of all, if choose ordinary filter oil machine.The oil in the hair of prefilter can filter fiber and some coarser particles, the pump will be filtered hair oil transfer into a small manual compression plate and frame filter press, through the filter, the oil of solid impurities trapped on the surface of filter press filter, a small amount of water absorbed by the wool stoma of filter paper.Due to oil contains impurities and moisture is more, filter paper you need often change, and change the filter paper to stop operation, the operation process more troublesome.And the filter process, the filter paper can only absorb the small amount of water in oil, and can't effectively reduce the moisture content.So, common filter oil machine for oil palm YouMao filtering are not suitable.
Second, if choose the vacuum filters oil machine.Take out the vacuum tank air to form a vacuum, vacuum pump oil under the action of atmospheric pressure, after entrance pipe into the prefilter, remove larger particles, and then enter the heating tank, after heating of 40 ~ 75 ° C oil through automatic oil floating valve, the valve is automatically control the amount of oil into the vacuum tank in and out of balance
.After heating the oil by spray wing whizzes, oil separation into half fog, the moisture in oil rapidly evaporate into water vapor and continuous vacuum pump in the condenser.Into the steam back into water again after cooling condenser, oil in vacuum heating tank, are djinn drainage pump filter through particles in the filter paper or filter will filter out impurities,To complete the vacuum filters oil machine rapidly process to remove impurities, moisture content, gas in the oil, palm oil oil clean.When in the qing filter filter adsorption too much impurity, vacuum tank pressure will
increase, need to replace the filter paper in time.Palm YouMao oil contains impurities is more, need to change the frequency of the filter paper will increase, not conducive to continuous operation.
Again, multifunction filter oil machine column in waste oil regeneration device integration, with the principle of physical, chemical, oil regeneration.Although can get purification is the perfect palm oil oil, but it also faces need to replace filter problem at any time, and is expensive, not suitable for small oil equipment processing workshop.
Finally, if choose centrifugal filter oil machine.Hair oil through high-speed rotation, oil, water and impurity effect under different centrifugal force and fast separation, in centrifugal field or gravitational field is obtained in different settling velocity, separation layer or the purpose of the settlement of solid particles in the liquid.Separating impurities attached impurities in collecting cover inside the rotor,
Simply wash regularly.In addition, due to the density of water is bigger than oil, under the action of centrifugal force, the water separated from the oil is the rotor inner product oil pan, only need to remove when the cleaning.Oil isolated by gravity flow directly.This machine is easy to operate, stable running, high safety performance and the price is moderate, suitable for small oil processing mill.But its separating oil may also contain a small amount of moisture and puree.
To sum up: from the point of view of satisfy the basic requirement, can choose the vacuum filters oil machine with small palm oil extraction equipment form a complete set of palm oil filtering equipment.The filtering device
is not the most ideal, of course, the main problem is the palm YouMao oil contains a large number of moisture, fruit pulp and fibre slag, if the use of filter paper or filter filter,Often requires a large number of filter paper or filter, must change the filter paper or filter, increase the operation steps;Without the use of filter paper or filter filtration, adopt the way of centrifugation, fruit pulp, water and oil can't ensure that can completely separate.From the point of view of the oil palm industry development in the future, the research and design the special oil palm YouMao filter filter oil machine is the best choice.
Design principle is to use the centrifugal combined with filter paper or filter to filter way, the hair after centrifugal oil first separated filter, filter out the oil contains only a small amount of moisture and puree;Again through the adsorption effect of filter paper or filter, the last of a small amount of moisture and fruit pulp adsorption, completely guarantee the oil clean thoroughly.
