Description

Technical Field

[0001] This utility model relates to a rapeseed oil purification device, belonging to the field of rapeseed oil production technology. Background Technology

[0002] Rapeseed oil is a common edible oil, and pressing is the most common production process. Pressing extracts oil by squeezing rapeseed, without using chemical solvents, thus preserving more nutrients and natural flavor. However, pressed rapeseed oil contains many impurities, which affects its quality and stability. Traditionally, filtration is used to remove impurities, but this method is slow and inefficient.

[0003] In the processing of rapeseed oil, adsorption decolorization is necessary to improve its quality and stability, removing pigments and impurities. Commonly used adsorption decolorizing substances include bleaching clay, activated clay, activated carbon, and silica gel. These substances effectively adsorb impurities from the oil, thereby improving its quality. However, existing adsorption treatment methods suffer from slow adsorption speed and low efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology by providing a rapeseed oil purification device that can improve the efficiency of oil purification and ensure the quality of rapeseed oil.

[0005] The purpose of this invention is to provide a rapeseed oil purification device, characterized by comprising: a housing, a pressing head assembly, and an adsorption assembly. The housing is used to hold the pressed rapeseed oil, the pressing head assembly is located directly above the housing, and the adsorption assembly is located on the top of the four side walls of the housing.

[0006] In the above scheme, an external force causes the pressure head assembly to reciprocate upward and downward, causing the rapeseed oil in the tank to continuously diffuse to all sides and come into contact with the adsorption assembly, thus trapping impurities in the rapeseed oil on the adsorption assembly. The continuous up-and-down movement of the pressure head assembly causes the rapeseed oil to continuously overflow and come into contact with the adsorption assembly for purification.

[0007] Furthermore, the top of the four side walls of the box is provided with inclined baffles, and baffles are provided on both sides of the baffles to prevent rapeseed oil from overflowing; the adsorption component is located above the baffles and is arranged parallel to the baffles.

[0008] In the above scheme, one end of the baffle wall is connected to the top of the side wall of the box, and the other end is arranged upward and outward with two baffles. This can allow the rapeseed oil to overflow under the action of the pressure head and come into contact with the adsorption components, and can also help the purified rapeseed oil to fall back into the box smoothly, while preventing the rapeseed oil from overflowing outside the box.

[0009] Furthermore, the pressure head assembly includes a pressure rod, a pressure head, and a pressure cap; the pressure cap covers the top of the housing, and the pressure rod is slidably assembled with the pressure cap; the pressure head is located inside the housing and fixed to the bottom end of the pressure rod. Under the action of external force, the pressure rod moves up and down, driving the pressure head to move up and down.

[0010] Furthermore, all four side walls of the pressure head are sloped, forming a structure that is wider at the top and narrower at the bottom. During the descent of the pressure head, the sloped structure of the pressure head and the inner side wall of the chamber form a flow channel that is narrower at the top and wider at the bottom, allowing the rapeseed oil liquid in the chamber to flow smoothly and stably to the baffle wall and come into contact with the adsorption component for purification.

[0011] Furthermore, the adsorption assembly includes a track, an adsorption plate mounted on the surface of the track, and the surface of the adsorption plate is provided with a plurality of small conical barbs.

[0012] In the above scheme, due to the inclined arrangement of the tracks, only the tracks at the lower position (adsorption plates) participate in the purification work, while the tracks at the higher position (adsorption plates) do not come into contact with the rapeseed oil. When the lower-position adsorption plates have intercepted a large number of impurities or have been used for a long time, the tracks can be driven to adjust the adsorption plates that were originally at the higher position to the lower position to participate in the purification work, while the adsorption plates that were originally at the lower position are adjusted to the higher position for replacement or cleaning.

[0013] The adsorption plate can adsorb impurities in rapeseed oil. The multiple small conical barbs on the surface of the adsorption plate form multiple flow channels, which not only increases the adsorption area but also prolongs the residence time of rapeseed oil on the adsorption plate, thus improving the purification effect.

[0014] Furthermore, a propeller blade is provided at the bottom of the inner cavity of the chamber, and the propeller blade is located directly below the pressure head assembly. The propeller blade can be controlled by a motor. By driving the propeller blade, the rapeseed oil liquid in the chamber is fully stirred, keeping impurities in a suspended state and preventing them from settling. Then, it is sent to the adsorption plate for purification through the descending pressure head.

[0015] Furthermore, the top of the retaining wall extends downwards with an inclined ramp, and side plates are respectively provided on both sides and the tail end of the ramp to form an impurity collection hopper. When the lower-level adsorption plate has intercepted a large amount of impurities or the usage time is long, the track can be driven to adjust it to a higher position, and an air gun or other method can be used to separate the impurities from the adsorption plate and let them fall into the impurity collection hopper.

[0016] In use, this utility model uses an external force to drive the pressure head assembly to perform a reciprocating lifting motion: when the pressure head of the pressure head assembly descends, the rapeseed oil diffuses and overflows to the four sides of the box and comes into contact with the adsorption assembly, causing impurities to be intercepted on the adsorption assembly; when the pressure head of the pressure head assembly rises, the rapeseed oil purified by the adsorption assembly falls back into the box.

[0017] This invention has a simple structure and is easy to operate. It can be used in small rapeseed oil processing plants, effectively ensuring the quality of rapeseed oil and improving the purification efficiency of rapeseed oil liquid. Attached Figure Description
