Description

Technical Field

[0001] The invention relates to the technical field of primary processing of agricultural products, and in particular to a device for extracting whole oat kernels. Background Art

[0002] Oatmeal is made by rolling whole oats. Oats are a kind of slender seeds with a relatively soft skin and fragile kernels. When the existing equipment is used for processing, the oat kernel breakage rate is high, causing additional losses to farmers. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides an oat whole-grain kernel extraction device, which can ensure the integrity of the oat kernel when extracting the oat kernel, has low temperature rise and small nutritional loss, and is suitable for use by various oat food processing enterprises.

[0004] The present invention is achieved through the following technical solutions:

[0005] Provided is an oat whole grain kernel extraction device, comprising a base and a cover, a shell fixed on the top of the base, a feed inlet is provided on the top of the shell, a rotor is rotatably installed in the shell above the base, and a vibrator that can vibrate up and down is slidably sleeved on the outer periphery of the rotor, a spiral guide groove is provided on the inner wall of the vibrator, the inner diameter of the spiral of the vibrator guide groove forms a clearance fit with the outer wall of the rotor, the upper part of the guide groove is connected with the feed inlet, an inclined and annular belt-shaped discharge slide rail is fixed to the outer wall of the vibrator, and the outer side of the vibrator discharge slide rail forms a clearance fit with the inner wall of the equipment shell; a cavity is provided between the inner wall and the outer wall of the vibrator, a first opening that connects the guide groove with the cavity is provided on the inner wall of the vibrator at the bottom of the cavity, a second opening is provided on the outer wall of the vibrator at the upper part of the cavity corresponding to the high end of the discharge slide rail, a discharge inlet is provided at the lower part of the shell corresponding to the low end of the discharge slide rail, a hull outlet is provided at the upper part of the shell on one side of the feed inlet, and the hull outlet is connected to an externally placed grounded vacuum pump.

[0006] This solution allows whole oats to flow through different working rooms, where the oats are subjected to one or more combined forces such as vibration, friction, and negative pressure. At the same time, the oats are constantly squeezed, collided, and rubbed against each other, so that the oat skin is torn and the oat kernel is completely exposed, thereby ensuring the integrity of the whole oat kernel.

[0007] Preferably, the spacing between the guide grooves is wider at the top and narrower at the bottom.

[0008] The spacing on the guide groove is set to be wider at the top and narrower at the bottom. The purpose is to greatly increase the squeezing, collision and rubbing force between the oats when the oats flow through the guide groove, causing the oat skin to break and fall off, and obtain complete oat kernels.

[0009] Furthermore, a feed barrel is installed at the feed port on the top of the shell, a feed flow regulator is installed inside the feed barrel, and a feed handle for controlling the feed flow regulation is installed outside the feed barrel.

[0010] A feed barrel is installed at the feed port of the outer shell, and the material is fed through the feed barrel. When feeding, the feed flow rate can be adjusted by the feed handle on the feed barrel to make the feeding more stable. At the same time, it cooperates with the discharge flow regulator to ensure the stability and smoothness of the equipment operation.

[0011] Furthermore, a discharge box is installed at the discharge port at the bottom of the shell, a discharge flow regulator is installed in the discharge box, and a discharge handle for controlling the discharge flow regulation is installed outside the discharge box.

[0012] The discharge box is installed at the discharge port to collect the discharged materials. By installing a flow regulator, the discharge flow rate can be conveniently controlled through the discharge handle, which is used in conjunction with the feed flow regulation to ensure the stable operation of the equipment.

[0013] Furthermore, a truncated cone-shaped distributor is fixed on the top of the rotor, and the top surface of the distributor is flush with the plane of the feed inlet.

[0014] The distributor is in the shape of a truncated cone, and its conical circumference can be used to distribute the material entering from the feed inlet. As the rotor rotates, after coming into contact with the oat particles, it can impart an angular velocity to the oat particles, so that they are evenly dispersed and smoothly enter the area between the rotor and the vibrator, and enter the interior of the equipment from the guide groove.

[0015] Furthermore, a hollow truncated cone-shaped material baffle is fixed at the feed inlet in the shell, and the bottom of the material baffle extends to the top of the vibrator.

[0016] The material is blocked by installing a baffle plate in the shell, so that the material entering from the feed port can completely enter between the rotor and the vibrator, making it easier for the oat particles to enter the guide groove.

[0017] Furthermore, a rotating motor for driving the rotor to rotate and a vibration motor for driving the vibrator to vibrate are respectively installed in the base.

[0018] The rotation of the rotor is driven by a rotary motor, and the vibration of the vibrator is achieved by a vibration motor.

[0019] Furthermore, a control panel is installed on one side of the base, and the control panel is electrically connected to the rotating motor and the vibration motor respectively.

[0020] By setting a control panel, which is electrically connected to the rotating motor and the vibrating motor respectively, each electrical device can be controlled through the control buttons on the control panel, which is convenient for operation and use.

[0021] Furthermore, an observation port is provided on the shell and an observation window is installed at the observation port.

[0022] An observation port is set up, and the internal operation of the shell can be observed by installing an observation window, so that the internal operation of the equipment can be understood at any time. At the same time, when blockage occurs inside the equipment, it can be unblocked through the observation port to facilitate maintenance.

[0023] Preferably, a polymer coating is attached to the surface of the rotor.

[0024] The function of the polymer coating is to increase the friction between the oatmeal surface and the outer wall of the rotor.

[0025] Beneficial effects of the present invention:

[0026] The present invention can obtain complete oat kernels, and the oat kernel whole grain rate is high; the oats do not need to be graded before processing, which reduces the investment cost of the equipment; at the same time, the present invention has low energy consumption and high output, which reduces the electricity burden of oat deep processing enterprises. The present invention can effectively take out the oat husks, the oat kernel has a low husk content, no water is needed during the operation of the device, the temperature rise is low, the nutritional loss of the oats is small, and the nutritional value of the oats is maintained to a great extent.

[0037] The vibrator 13 is an ultrasonic vibrator, and a spiral guide groove 21 is provided on the inner wall of the vibrator 13. The spiral inner diameter of the guide groove 21 forms a clearance fit with the outer wall of the rotor 14, and the spacing of the guide groove 21 is wide at the top and narrow at the bottom.

[0038] The upper part of the guide groove 21 is connected with the feed port 9, and an inclined and annular discharging slide rail 12 is fixed to the outer wall of the vibrator 13, and the outer side of the discharging slide rail 12 is clearance-matched with the inner wall of the shell 1. A cavity 17 is provided between the inner wall 22 and the outer wall 23 of the vibrator 13, and a truncated cone-shaped distributor 11 is fixed to the top of the rotor 14, and the top surface of the distributor 11 is flush with the plane of the feed port 9. A hollow truncated cone-shaped baffle plate 25 is fixed at the feed port 9 in the shell 1, and the bottom of the baffle plate 25 extends to the top of the vibrator 13.

[0039] A first opening is opened on the inner wall of the vibrator 13 at the bottom of the cavity 17 to connect the guide groove 21 with the cavity 17, a second opening 19 is opened on the outer wall of the vibrator 13 at the upper part of the cavity 17 corresponding to the high end of the discharge slide rail 12, a discharge port 16 is opened at the lower part of the outer shell 1 corresponding to the low end of the discharge slide rail 12, and a skin discharge port 10 is opened on the upper part of the outer shell 1 on one side of the feed port 9, and the skin discharge port 10 is connected to an external ground-mounted vacuum pump (the vacuum pump is not shown in the figure).

[0040] A discharge box 6 is installed at the discharge port 16 at the bottom of the housing 1 , a flow regulator is installed inside the discharge box 6 , and a discharge handle 5 for controlling the discharge flow rate is installed outside the discharge box 6 .

[0041] Inside the shell 1, the inner wall 22, the outer wall 23 and the bottom wall of the vibrator 13, that is, the cavity 17 of the vibrator 13, are the second working room. The inlet of the second working room, that is, the first opening, is located below the vibrator 13, and the outlet, that is, the second opening 19, is located above the vibrator 13; the inner wall 22 of the vibrator 13 and its guide groove 21 and the outer wall of the rotor 14 together constitute the first working room 15, whose inlet is connected to the feed port 9, and whose outlet is connected to the second working room, that is, the cavity 17; the outer wall of the vibrator 13 and the discharge slide rail 12 and the inner wall of the shell 1 constitute the third working room 20, whose inlet is connected to the outlet of the second working room, that is, the cavity 17, and the outlet is directly connected to the discharge port 16 on the equipment shell 1.

[0042] A rotating motor for driving the rotor 14 to rotate and a vibration motor for driving the vibrator 13 to vibrate are respectively installed in the base 2. A control panel 7 is installed on one side of the base 2, and the control panel 7 is electrically connected to the rotating motor and the vibration motor respectively.

[0043] Working process of the present invention:

[0044] In the preparation stage, start one or more negative pressure vacuum pumps outside the equipment to stabilize the third working room 20 at a certain negative pressure value. Use the buttons on the control panel 7 to start the rotor 14 and the vibrator 13 respectively, and pay attention to whether the direction of the rotor 14 is normal (the specific judgment of the rotor direction is based on the smoothness of material feeding. If the rotor direction is normal, the material feeding is smooth. If it is blocked and the material cannot be fed, the direction needs to be adjusted). Pour a small amount of oat raw material into the feed barrel 3, open the feed port 9, and adjust the flow rate of the feed port 9 through the feed handle 4, so that the oats slowly enter the distributor 11, and then flow through the first working room 15, the second working room (cavity 17) and the third working room 20 in turn. The oat kernel flows out through the discharge port 16, and the oat husk flows out through the husk outlet 10, and is discharged through the outlet of the vacuum pump.

[0045] In the process of oat particles entering the housing 1 from the feed port 9 below the feed barrel 3 and exiting from the discharge port 16, the oats are subjected to the combined action of the rotor 14 and the vibrator 13 in the first working room 15, and violent collision and rubbing occur between the oats, the connection between the oat husks and the oat kernels is destroyed, and most of the oat husks fall off. When passing through the second working room (i.e., the cavity 17), the remaining small part of the adhered oat husks and oat kernels are separated under the vibration of the vibrator 13. Since the third working room 20 is filled with negative pressure, the completely separated oat husks and oat kernels enter, and the oat husks are subjected to the negative pressure and move along the Figure 3 The oat kernels flow out from the hull outlet 10 in the direction of the dotted line, while the oat kernels flow out from the outlet 16 along the outlet slide rail 12.

[0046] According to the effect of the oat kernels at the outlet, the feed inlet flow, negative pressure value, rotor speed, oscillator amplitude and frequency are gradually corrected until a satisfactory effect is achieved; after the parameters are adjusted, oats are poured in for continuous batch production and processing.
