Description
Technical field
The present invention relates to the squeezing process of a vegetable oil, particularly the technique of vegetable oil low-temperature cold press.
The invention still further relates to the press apparatus that this technique adopts.
Background technology:
The low temperature pressing technology of domestic vegetables oil mainly contains screw press and hydraulic pressure squeezing two large classes.One is low temperature screw press, is to become gradually large screw shaft by the transmission of power by diameter, utilizes screw shaft squeezing continuous rotation in hall, promotes oil plant and makes oil plant pressurized and get oil gradually.But can produce heat due to oil plant pressurized and with the screw rod friction of rotation.So, so-called low temperature screw oil-extracting is relative low temperature, compared with general screw oil-extracting, the one, oil plant is entering the temperature of controlling charging before crusher in 50 degree left and right, and oil plant temperature to be brought up to 120-130 ℃ before general screw oil-extracting charging, the 2nd, squeeze hall space etc. by the rotating speed that reduces screw rod with the length, the adjustment that increase screw rod, the friction of oil plant and screw rod, squeezing hall is reduced, thus the heat that minimizing extruding produces.From the situation of the low temperature expeller of current domestic production, pressure is all not less than 80-100 ℃ in the oil plant temperature in oil plant exit when maximum.Another kind is that low temperature hydraulic pressure squeezing is to utilize pressure that hydraulic efficiency system produces to get oil to the container of oil plant is housed pushes.The equipment of comparative maturity has classical 90 types and semi-automatic 230 types etc. at home at present, is to be extruded at normal temperatures to get oil with the oil plant that this kind equipment is produced, and is the low temperature pressing in meaning, but is all the production of interval type.90 types can have the container of multiple constancies of volume to build to gather together and push through the pressure of hydraulic system transfers, the pressurized thickness of oil plant, and the size that oil cake thickness can be set container in advance according to the character of oil plant regulates, generally at 8-10cm.Because the vessel volume of charge of oil material is fixed when each squeezing, when being forced into fixed volume, oil plant just cannot press again, and this is concerning the larger oil plant of some plasticity-, and because there is no enough pressure, fuel-displaced just undesirable, oil yield is lower.The container of 230 type charge of oil material is in the form of piston, vessel volume reduces with the increase of pressure, oil plant can be subject to the extruding of hydraulic system transfers pressure always, but because this equipment only has an oil plant container, when each squeezing, the thickness of oil plant is thicker, and while producing general oil plant, the thickness of the rear oil cake of squeezing is in 20-30cm left and right.The thickness of oil plant is thicker, and the pressure of buffering, absorption is just larger, and the pressure that oil plant is subject to is just less.So this equipment also exists because oil plant plasticity-is large, oleaginousness is high and can not reach desirable fuel-displaced, and oil yield is low, does not even go out oily problem.
Summary of the invention
Object of the present invention is intended to overcome the defect of prior art, provides one under normal temperature condition, to process oil plant, the vegetable oil low-temperature cold pressing process of the oil plant that particularly plasticity-is large, oleaginousness is higher.
Another object of the present invention is to provide the press apparatus of this vegetable oil low-temperature cold pressing process.
Vegetable oil low-temperature cold pressing process of the present invention, comprises metering, installation, squeezing and release, and its step is as follows:
A. POL measuring;
B. oil plant packs oil plant filter bag into, and oil plant filter bag packs squeezing machine into;
C. pressurization, pressurize, obtains pressed oil;
D. pressed oil filters, check is rear packs;
E, release, takes oil plant filter bag away, blob of slag packing.
The thickness that packs into of step B oil plant is 3-30 centimetre, and after squeezing, the thickness of a blob of slag is at 1.5-15 centimetre.
Pressurization described in step C, squeeze pressure is 100-600 kg/cm.
Pressurization described in step C, the time of pressure process is 5-45 minute, the dwell time is 10-50 minute.
Pressurize described in step C, after squeezing, the oil-containing of a blob of slag is 7-23%.
Vegetable oil low-temperature cold press press disc type press apparatus of the present invention, formed by oil plant filter bag, gland, squeezing disk, frame, Hydraulic Station and hydro-cylinder, gland is placed on squeezing disk, the diameter of gland is less than squeezing disk internal diameter 2-3 millimeter, has oil guiding hole on gland, and oil guide groove is arranged at squeezing disk top, on wall, there is oil guiding hole, oil drain pan is arranged at the bottom of squeezing disk, and oil drain pan is connected with oil outlet, and Hydraulic Station provides the pressure of oil expression for hydro-cylinder.
Described oil plant filter bag is that the flexible materials with toughness makes, and is the one in cloth bag, paper bag, Fibre Bag, non-woven bag.
Described squeezing disk is more than 1, can determine according to actual needs its quantity, and its diameter each other not etc., is not trapezoidal arrangement.Oil guiding hole diameter on described gland and on squeezing disk wall is 0.5-2.5 millimeter, and the spacing between oil guiding hole is 3-15 millimeter.
Vegetable oil low-temperature cold press column type press apparatus of the present invention, formed by hydraulic efficiency system and cylindrical oil expression cylinder and top cover, hydraulic efficiency system is as a whole with oil expression cylinder, a hydraulic efficiency system comprises Hydraulic Station, hydro-cylinder, a hydraulic efficiency system and an oil expression cylinder are supporting, pressure required while oil expression is provided, oil expression cylinder divides inside and outside two-layer, internal layer surrounds oil plant container by bar shaped steel, gap between steel bar is oil guide groove, oil guide groove and oil-containing groove UNICOM, oil outlet be positioned at oil expression cylinder bottom, and with oil-containing groove UNICOM.
Described oil expression cylinder is divided into multilayer by oil plant layering dividing plate (12), and the oil plant in each layer contains with oil plant filter bag.
Vegetable oil low-temperature cold pressing process of the present invention and equipment are interval type normal temperature hydraulic cold oil tech and equipment.Can extract oil to different oil plants at normal temperatures, squeeze the grease in oil plant, be specially adapted to the oil plant that plasticity-is large, oleaginousness is high, need low-temperature cold pressing.The oil plant filter bag of the technology of the present invention equipment adopts the container that can change with pressure and oil plant, both having solved similar 90 type oil press zhai can not increase and change with pressure in when oil expression because of oil plant filter bag volume, cause the low difficult problem of oil plant oil yield that plasticity-is large, oleaginousness is high, also solve similar 230 type oil press zhai because oil plant volume is excessive, cake of press thickness is thicker, caused the difficult problem that pressure is inadequate, oil yield is low, even not fuel-displaced.The grease of producing is low temperature cold oil expression truly, has retained to greatest extent original nutritive ingredient in vegetables oil, genuineness.Because whole process is carried out at normal temperatures, the nutritive substances such as the protein after squeezing in cake are not damaged or sex change simultaneously, play a positive role for further developing plant series food.
