Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain and oil technology, and in particular to a quality testing device for rice bran oil. Background Technology
[0002] The impurity content in edible oil is an important indicator of its quality. Excessive impurities can seriously affect the safety of edible oil, especially when stir-frying at high temperatures, which can produce a large number of harmful substances. Therefore, it is necessary to test for impurities.
[0003] In existing edible oil quality testing, staff usually use handheld edible oil quality testing instruments, which need to be manually cleaned before and after use, affecting testing efficiency and causing great inconvenience. Therefore, this application discloses a quality testing device for rice bran oil. Utility Model Content
[0004] The purpose of this invention is to address existing problems by providing a quality testing device for rice bran oil.
[0005] This utility model is achieved through the following technical solution: a quality testing device for rice bran oil, comprising a frame, a hopper mounted on the frame, a vertically mounted shaft inside the hopper, a motor output shaft connected to the upper end of the shaft, a motor mounted on a hopper cover, the hopper cover connected to the upper port of the hopper, several stirring rods evenly distributed on the shaft, a discharge pipe connected to the lower end of the hopper, an electric valve installed in the discharge pipe, a disc cover installed at the lower end of the discharge pipe, the disc cover being supported and connected to a plate base by a cylinder, the plate base being mounted on a support rod, the support rod being installed inside the frame, jet nozzles and liquid spray nozzles evenly distributed on the hopper and the discharge pipe, and a detector installed at the bottom of the disc cover.
[0006] As a further improvement to the above solution, the electric valve includes a door plate, which is rotatably disposed inside the discharge pipe. The door plate is connected to a rotating rod, which rotates and is connected through the discharge pipe. One end of the rotating rod is connected to the output shaft of a motor, and the motor is installed on the outer wall of the discharge pipe. The motor drives the rotating rod to rotate at a specified angle, and the door panel also rotates accordingly. If the door panel rotates to a horizontal position, it seals the discharge pipe, restricting the discharge of rice bran oil from the hopper. If the door panel rotates to an inclined position, the discharge pipe is open, and the rice bran oil in the hopper is discharged from the discharge pipe. The same applies to the cleaning liquid sprayed through the spray nozzle.
[0007] As a further improvement to the above solution, a guide rod is vertically arranged around the periphery of the disc cover, with the lower end of the guide rod inserted into the sleeve, and the sleeve is vertically connected to the plate base; The disc cover, supported by a cylinder, extends and retracts within the sleeve via a guide rod, ensuring the balance of the disc cover during lifting and lowering.
[0008] As a further improvement to the above solution, a drain pipe is provided through the cover, and a valve is provided on the drain pipe to discharge the oil and cleaning fluid contained in the cover.
[0009] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. The stirring rod driven by the motor stirs the rice bran oil in the tank, so that the rice bran oil is fully stirred and filled with air bubbles, which separates the impurities in the oil and makes it easier for the tester to detect the quality of the rice bran oil. In addition, the high-pressure cleaning fluid connected to the spray head cleans the inner wall of the tank, the inner wall of the pipe, and the door panel to prevent the rice bran oil from adhering to them. The jet head connected to the high-pressure gas removes water stains from the inner wall to avoid affecting the next oil test. The door panel is driven by the motor to rotate, so that the door panel is in an inclined and horizontal position, that is, to discharge liquid and close the seal. The sealed position facilitates the stirring of rice bran oil, and the open position facilitates the emptying of rice bran oil and the discharge of a small amount of rice bran oil onto the plate cover for oil test.

[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] like Figures 1 to 4 As shown, a quality testing device for rice bran oil includes a frame 1, on which a hopper 2 is mounted. A shaft 5 is vertically mounted inside the hopper 2, with the upper end of the shaft 5 connected to the output shaft of a motor 4. The motor 4 is mounted on a can cover 3, which is connected to the upper port of the hopper 2. Several stirring rods 6 are evenly distributed on the shaft 5. A discharge pipe 7 is connected to the lower end of the hopper 2, and an electric valve is installed inside the discharge pipe 7. A disc cover 11 is installed at the lower end of the discharge pipe 7, and the disc cover 11 is supported and connected to a plate base 13 by a cylinder 12. The plate base 13 is mounted on a support rod 14, which is installed inside the frame 1. Air jets 17 and liquid spraying heads 18 are evenly distributed on the hopper 2 and the discharge pipe 7. A detector is installed at the bottom of the disc cover 11, and the detector probe 20 is placed inside the disc cover.
[0016] As a further improvement to the above solution, the electric valve includes a door plate 8, which is rotatably disposed inside the discharge pipe 7. The door plate 8 is connected to a rotating rod 9, which rotates and is connected through the discharge pipe 7. One end of the rotating rod 9 is connected to the output shaft of the motor 10, and the motor 10 is installed on the outer wall of the discharge pipe 7. When the motor 10 operates, it drives the rotating rod 9 to rotate at a specified angle, and the door panel 8 also rotates accordingly. If the door panel 8 rotates to a horizontal position, it seals the discharge pipe 7, restricting the discharge of rice bran oil from the hopper 2. If the door panel 8 rotates to an inclined position, the discharge pipe 7 is open, and the rice bran oil in the hopper 2 is discharged from the discharge pipe 7. The same applies to the cleaning liquid sprayed through the spray head 18.
[0017] As a further improvement to the above solution, a guide rod 16 is vertically arranged around the periphery of the disc cover 11, and the lower end of the guide rod 16 is inserted into the sleeve 15, which is vertically connected to the plate base 13. The disc cover 11, supported by the cylinder 12, extends and retracts within the sleeve 15 via the guide rod 16, ensuring the balance of the disc cover 11 during lifting and lowering.
[0018] As a further improvement to the above solution, a drain pipe is provided through the cover 11, and a valve is provided on the drain pipe to discharge the oil and cleaning fluid contained in the cover 11.
[0019] The working principle of a rice bran oil quality testing device is as follows: Rice bran oil is added to the tank 2 through the oil filling hopper 31. The motor 4 drives the stirring rod 6 to stir the rice bran oil in the tank 2, so that the rice bran oil is fully stirred and filled with air bubbles, which removes impurities from the oil and makes it easier for the tester to detect the quality of the rice bran oil. In addition, the high-pressure cleaning fluid connected to the spray head 18 cleans the inner wall of the tank, the inner wall of the pipe, and the door panel 8 to prevent rice bran oil from adhering to them. The jet head 17 connected to the high-pressure gas removes water stains from the inner wall to avoid affecting the next oil test. The door panel 8 is driven to rotate by the motor 10, so that the door panel 8 is in an inclined and horizontal position, that is, to discharge liquid and close the seal. The sealed position facilitates the stirring of rice bran oil, and the open position facilitates the emptying of rice bran oil and the discharge of a small amount of rice bran oil onto the plate cover 11 for oil test.
[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
