Description

An oil press}

The present invention relates to an milking machine, and more specifically, to an milking machine that pushes the milked sludge forward along the line by the rotation of the screw, and at the same time re-presses the milked sludge to re-milk it.

In general, an oil expeller extracts edible oil by compressing various grains such as sesame seeds, perilla seeds, etc., and their powders. A compression type expeller using hydraulic pressure and a squeeze type expeller using a screw have been developed and used.

The compression type milking machine using the hydraulic pressure includes a main body, a hopper into which grain is introduced into the upper part of the main body, a pressurizing member for pressing grain at the lower part of the hopper, an milking tank for discharging grain oil into the main body, and It has a basic structure in which a cylinder is provided at the bottom of the milking trough, and grains that have been roasted for a certain period of time are put into the milking trough, and oil is milked by the pressurizing force that causes the cylinder at the bottom to rise and fall.

However, since hydraulic oil expellers simply extract oil using pressure, the work must be done quickly before the heat of the grains cools down. If there is a delay and the grains cool down, the grains become hard and the oil cannot be squeezed out well.

In addition, the compression type milking machine using a screw is configured to milk milk by operating the transfer screw and milking screw with the power of the motor. As a prior art of the compression type milking machine using the screw, the milking machine has been registered in Korea Registered Utility Model Publication No. 20-0183012. In this prior art, grains such as sesame seeds roasted through a separate roaster are put into the hopper, and then the drive unit is driven under the control of the control unit, and the transfer and compression action of the transfer screw and milking screw are carried out according to the rotation of the shaft bar connected to the drive unit. Milking takes place inside the grid assembly, and the oil is discharged to the oil guide rail through the oil discharge channel formed in the grid assembly. In addition, oil-based seed cake, or sludge, passes through the grid assembly, collides with the blade at the same time, is cut off, and collides with the diffusion portion to disperse, so that it can be easily discharged into the seed cake collection bin.

However, the prior art has a problem in that the seed meal milked from the milking screw is not smoothly discharged to the outside of the lattice assembly because it rotates along the milking screw.

In addition, there is a problem in that milking efficiency is reduced because the sesame water discharged along the grid assembly is not re-pressed.

In addition, the structure of the grinding tool for grinding the seed cake is complicated, making it difficult to manufacture, and there is a problem in that the manufacturing cost increases.

Referring to FIG. 1, the milking machine 100 according to one embodiment includes a motor 110, a drive shaft 120, a transfer screw 130, a milking screw 140, a hopper 150, and a cylinder 160. can do.

The motor 110 may be a rotating member that rotates under the control of a controller. The drive shaft 120, the transfer screw 130, and the milking screw 140 can be rotated by the power of the motor 110 that rotates according to the rotation of the control unit.

The drive shaft 120 is connected to the motor 110 and may be a shaft that transmits the power of the motor 110 to the transfer screw 130 and the milking screw 140.

The transfer screw 130 may be a screw that is connected to the drive shaft 120 and rotates with the power of the motor 110 to move grain supplied from the hopper 150 to the milking screw 140.

The milking screw 140 may be a screw that pressurizes and milks grains transferred to the transfer screw 130.

The hopper 150 may be a member that guides grains input from the outside to the transfer screw 130.

Referring to Figures 2 and 3, the cylinder 160 is coupled to the milking screw 140 and is configured to guide the discharge of the sludge milked from the milking screw 140, and includes a body 161 and a line 162. It can be included.

The body 161 has a penetrating interior and can be coupled to the milking screw 140.

Line 162 can prevent rotation of sludge by milking screw 140. The line 162 is radially recessed in the longitudinal direction on the inner peripheral surface of the body 161 and may include a vertical surface 162a and an inclined surface 162b.

The vertical surface 162a may be formed to be recessed from the inner peripheral surface of the body 161 toward the outer peripheral surface.

The inclined surface 162b may be a surface connecting the end of the vertical surface 162a recessed in the direction of the outer peripheral surface of the body 161 and the inner peripheral surface of the body 161. The inclined surface 162b may be formed to be curved.

The vertical surface 162a and the inclined surface 162b may be formed sequentially or alternately.

Referring to FIG. 4, the inclined surface 162b may be formed to be inclined so that the direction in which sludge is discharged is narrower than the direction in which sludge is introduced.

The following describes the operating process of the milking machine configured as above.

First, referring to FIG. 1, the motor 110 may be driven under the control of the control unit. As the motor 110 is driven, the drive shaft 120 connected to the motor 110, the milking screw 140 and the transfer screw 130 connected to the drive shaft 120 rotate, and the milking screw 140 and the transfer screw (130) The end may rotate within the outlet pipe 140'.

In this state, when grain is input into the hopper 150, the grain input into the hopper 150 is supplied to the transfer screw 130, and is simultaneously rotated by the transfer screw 130 and transferred in the direction of the milking screw 140. You can.

At this time, the transfer screw 130 can compress and milk the grain between the cylinders 160 while rotating the grain in the direction of the milking screw 140. Here, the streamlined screw blade of the transfer screw 130 can primarily milk the grain by compressing it while rotating it in the direction of the milking screw 140.

The grains primarily milked through the above process are transferred to the milking screw 140 by the transport screw 130, and the milking screw 140 rotates with the driving of the motor 110 to transfer the grains to the drive shaft 120. It can be rotated in any direction. At this time, the milking screw 140 can compress and milk grains between the cylinders 160 while rotating in the direction of the drive shaft 120. Here, the streamlined screw blade of the milking screw 140 can perform secondary milking by compressing the grain while rotating it in the direction of the compression pipe 120'.

The process of milking the grain is a normal process, and the oil milked through the above process passes through the outflow pipe 140', that is, the space between the grid assemblies, and then can be supplied to the storage space along the rail and stored. .

At this time, the cylinder 160 may be surrounded by a heating body, and the heat of the heating body may be transmitted to the cylinder 160.

As it is moved and compressed by the milking screw 140, the seed cake, or sludge, of the milked grain is moved inside the body 161 of the cylinder 160, and at the same time, the sludge moved inside the body 161 is moved to the milking screw 140. It can be rotated and moved to line 162. The sludge moved to the line 162 may stop rotating as it comes into close contact with the vertical surface 162a along the inclined surface 162b. In addition, in a state where the sludge is in close contact with the vertical surface 162a and rotation movement is stopped, the sludge placed on the inclined surface is in close contact with the vertical surface 162a due to the pressure of the sludge introduced into the line 162 and is pushed along the line 162. As this process is repeated, the sludge may be discharged to the outside of the cylinder 160.

When the sludge is pushed along the line 162, it is squeezed once again through the compression pipe 120' by the sludge introduced into the line and is milked three times, and the milked oil passes through the outflow pipe 140'. Afterwards, it can be supplied to a storage space along the rail and stored. Here, in some embodiments, the thirdly milked oil may be discharged through a discharge hole formed through the inclined surface 162b and then supplied to a storage space along the rail for storage.

In addition, the inclined surface 162b of the line 162 along which the sludge moves is formed to be inclined so that the direction in which the sludge is discharged is narrower than the direction in which the sludge flows, thereby further compressing the sludge moving along the line 162 and removing the oil. The milking rate can be increased by milking more.

Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. You will be able to understand it. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
