Description

  The present invention relates to a food powder sterilizing apparatus that accelerates powder at a high speed and collides with a rigid body of a collision member so as to sterilize bacteria attached to the powder.

    In general, sterilization is an effective means for improving food safety in food hygiene management. However, heat sterilization has a problem that the nutritional value and quality of food are deteriorated. In the case of the body, when heat sterilized, the properties of the food powder changed, and there was a problem that the food powder could not be used as it was.

In order to solve this problem, there is a device that puts powder on the speaker and sterilizes it by vibrating the sound generated by the speaker. In addition, there is a problem that the effect is not obtained so much that powder is not vibrated when extra powder is placed on the speaker.

  The problem to be solved is that in the case of food powder, when the heat sterilization, the properties of the food powder change, and the food powder cannot be used as it is.

  In the present invention, the container is provided with a diaphragm at the bottom, and a metal mesh that causes powder to collide with the vicinity of the diaphragm, the ultrasonic vibrator is attached to the diaphragm of the container, and the support member is The container equipped with the ultrasonic vibrator is supported, and the low-frequency vibration device mechanically vibrates the container together with the support member, so that the powder contained in the container is thinly spread on the diaphragm and attached to the bottom of the container. By ultrasonically oscillating with an ultrasonic vibrator, the powder is accelerated at high speed and collided with the vibration plate on the bottom surface of the container and the metal mesh or the rigid body of the punch member, so that the bacteria attached to the powder are removed. It will be sterilized by tapping.

  In the food powder sterilization apparatus of the present invention, the powder contained in the container is vibrated thinly on the vibration plate on the bottom surface of the container by vibrating with a low frequency vibration device, and in this state the container is When the vibrating plate is ultrasonically vibrated, the powder on the vibrating plate is accelerated at high speed by the ultrasonic vibration and collides with the vibrating plate and the rigid body of the metal mesh or punch member. There is an advantage that the bacteria attached to the body can be sterilized by being destroyed and killed.

  In the present invention, when the powder is piled thick and placed on the diaphragm in the container, the powder is thinly spread on the diaphragm of the container by a low frequency vibration device, and the thinly spread powder is subjected to ultrasonic vibration. By accelerating, the powder could collide with the diaphragm and the metal mesh or the rigid body of the punch member.

  FIG. 1 is a side sectional view of a food powder sterilizing apparatus according to an embodiment of the present invention. A punch 2 having a diaphragm 2 attached to the bottom of a container 1 and a mesh or a plurality of holes formed in the vicinity of the diaphragm 2 is shown. The member 3 is mounted, and the ultrasonic vibrator 4 is fixed substantially at the center of the diaphragm 2, the powder injection port 1 a is mounted on the upper part of the container 1, and the powder is taken out at the lower part of the opposing part of the container 1. The container 1 to which the discharge port 1b is mounted and the ultrasonic transducer 4 is fixed is supported by the support member 5, and vibration is generated by rotating the eccentric rotation member 6a eccentric to the bottom of the support member 5. An eccentric vibration device 6 is mounted, and a belt 8 hung on a pulley 7 fixed to a rotation shaft of the eccentric vibration device 6 is hung on a pulley 10 fixed to a rotation shaft of a motor 9.

  In the powder sterilizing apparatus of the present embodiment configured as described above, when the powder is put in the container 1 and the motor 9 is rotated, the eccentric vibration device 6 is driven by the belt 8 hung on the pulley 10 of the motor 9. By rotating the eccentric rotating member 6a, as shown in FIG. 2, a rotating low frequency vibration is generated as indicated by an arrow A, and the low frequency vibration is placed on the diaphragm 2 of the container 1 by this low frequency vibration. When the generated powder spreads thinly in the direction indicated by the arrow A and is generated so that ultrasonic waves are transmitted from the ultrasonic transducer 4 to the periphery of the container 1 as indicated by B in FIG. The powder spread on the vibration plate 2 is accelerated up and down by the sound wave, and by this acceleration, the powder collides with the vibration plate 2 and the collision member 3, and this powder becomes the vibration plate 2 and the metal mesh or punch member 3. The bacteria attached to the powder are killed when it collides with the rigid body of It is sterilized.

  Further, the vibration generated by the eccentric vibration device 6 is moved outward from the center of the diaphragm 2 of the container 1 as indicated by an arrow C in FIG. 4, and as indicated by an arrow D in FIG. Is moved parallel to the outside from the center line.

  The metal mesh 3 is formed with fine stitches 11 as shown in FIG. 6, and the punch 12 is formed with a large number of small holes 13 as shown in FIG.

  Using the powder sterilizer of FIG. 1, the ultrasonic vibrator 4 is driven at 37 kHz to vibrate the container 1, 200 g of defatted soybean powder is injected from the powder injection port 1a, and the discharge port is about 10 minutes later. As a result of taking out from 1b, the number of general viable bacteria can be reduced by about 73% (average of 10 tests: about 22,000 general viable bacteria at the time of injection, and 6000 general viable bacteria after removal). I was able to.

  FIG. 8 is a side cross-sectional view of a food powder sterilizing apparatus according to another embodiment of the present invention. 1 is a container, 2 is a vibration plate, 3 is a metal mesh or punch member, 4 is an ultrasonic vibrator, and 5 is a support. Members, 6 is an eccentric vibration device, 7 is a pulley, 8 is a belt, 9 is a motor, and 10 is a pulley. Since these configurations are the same as those in the above embodiment, the description thereof will be omitted. A support member 14 protruding downward is fixed to the plate 2, and an ultrasonic transducer 15 is connected to the support member 14, and an oscillation signal is transmitted from the oscillator 16.

    In the food powder sterilizing apparatus of the present embodiment configured as described above, the diaphragm 2 vibrates up and down by the ultrasonic vibrator 4 and lateral vibration is generated by the ultrasonic vibrator 15, thereby vibrating. Since complicated vibration is generated in the plate 2, the powder placed on the vibration plate 2 also generates complicated vibration. Therefore, the powder spread on the vibration plate 2 is accelerated vertically and horizontally, and by these accelerations, The powder collides with the rigid body of the diaphragm 2 and the metal mesh or the rigid body of the punch member 3, and when the powder collides with the rigid body of the diaphragm 2 and the collision member, bacteria attached to the powder are struck. Killed and sterilized.
