Description

[0001] Sterilizing Apparatus for Powder Type Food using Ozone [

The present invention relates to a food sterilizing apparatus, and more particularly, to a sterilizing apparatus for sterilizing a powdered powder of a crop powder with ozone at a low cost without changing the shape, taste, efficacy, The present invention relates to a powder type food disinfection apparatus using ozone which can remove harmful substances such as fungi and microorganisms and produce products from pure crops.

Generally, in order to produce powdered crops (ginseng, snakes, corn, potatoes, various herbs, etc.) as health food, wire, tea, etc., it is necessary to go through a process of removing bacteria and microorganisms.

However, because of the expensive equipments such as electron beam, ion beam, corona discharge, microwave, high vacuum heating, etc., it is very difficult to apply this process because the equipment cost and process ratio are higher than the product price.

So, although it uses a method of utilizing ion and UV as a low-cost equipment, sterilization power is considerably lowered, so sterilization is considered to be almost impossible so far.

In addition, the most widely used method is that it can not maintain its shape and taste due to the method of applying heat or heat deformation of the material, but also easily loses its efficacy in the case of health food materials.

In addition, when a fungicide is mixed, a consumer must be able to ingest a fungicide, and the taste and potency of the product must inevitably change.

On the other hand, it is possible to make the dryer which artificially dries various kinds of agricultural products to be small, to easily adjust the temperature and air volume of the warm air, and to supply / smoothly circulate hot air sterilized by the ozonizer into the drying chamber, A multipurpose agricultural product sterilizer dryer has been developed which is configured to minimize the temperature difference and to dry the agricultural products more hygienically and efficiently (refer to Korean Patent No. 0569149, "Multi-purpose agricultural product sterilizer dryer").

However, these sterilizers are difficult to apply to powdered crops because they are mounted on the sidewalls and bulkheads of the drying room in a building-like manner, and circulate the warm air produced by the heaters to the drying chamber, thereby changing the taste and efficacy of the crops. And there is no preparation against harmfulness of supplied ozone at all.

Korean Patent No. 0569149 (Mar. 4, 2006)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present embodiment, the same designations and the same reference numerals are used for the same components, and further description thereof will be omitted.

FIG. 1 is a perspective view showing a powder type food disinfection apparatus using ozone according to the present invention, and FIG. 2 is a partially separated perspective view showing a powder type food disinfection apparatus using ozone according to the present invention.

1 and 2, the powder type food disinfection apparatus using ozone according to the present invention includes a mixing cylinder 100, an ozone generator 200, an air pump chamber 300, an ozone remover 400, (600).

The mixing cylinder 100 is provided with a mixing fan 110 rotatable in order to mix the food powder received in a flat cylindrical shape with ozone. For example, the mixer 100 includes a volume Can be formed to about 250 liters.

The mixing fan 110 is connected to a motor unit 50 including a motor for rotating the blades at a speed of about 20 to 200 rpm, a gear unit, and other variable devices.

A mixing cylinder lid 120 is provided at an upper portion of the mixing cylinder 100 to be opened and closed by a tilting member 121 such as a hinge to prevent foreign matter from entering into the mixing chamber during operation .

The mixing cylinder lid 120 is provided with an ozone inlet and an ozone outlet through which ozone is supplied and discharged, respectively.

Here, it is preferable that the direction of the vanes of the mixing fan 110 is a reverse vane direction (vane direction in which the direction of wind generation is downward) for generating the air flow inside the mixing cylinder 100 in the bottom direction.

That is, in the case of the reverse vane direction, the air flow inside the mixing cylinder 100 moves to the bottom direction, then rides on the wall of the mixing cylinder (inner circumferential surface) to the ceiling and then forms the circulation of air descending again from the center of the ceiling do.

For example, when the rotating shaft rotates in the counterclockwise direction, when the blades of the mixing fan 110 are mounted in the reverse blade direction and wind is formed toward the bottom of the mixing cylinder 100, the sterilization time of the powder is 30 %, Respectively.

At this time, in order to increase the mixing property of the powders, the wings of the mixing fan 110 are extended from the middle height of the mixing cylinder 100 to opposite edges of the mixing cylinder 100, So as to extend to both opposite edges of the base.

The rotation speed of the blades of the blending fan 110 is basically in the range of 20 to 200 rpm, but the higher the rotation speed of the blades of the blending fan 110 is, the larger the particle size of the powder is. Is preferably 30 to 50 rpm.

In addition, the inclination of the blades 110 of the blending fan 110 needs to be optimized according to the particle size of the powder and the throughput of the blasting process. If the inclination of the blades is too large, the pressure inside the mixing blades 100 increases, Mixing with ozone air does not work well.

Therefore, it is preferable that the blade has a slope of 33 to 37 degrees when the mixing fan 110 has a blade rotation speed of 30 to 50 rpm in powder having a particle size of 50 to 70 mesh.

The wings of the mixing fan 110 may be variously formed in two, four, or the like, and then the blades may be rotated so that the blades are stacked in the mixing container 100, And it is needless to say that the inclination of the upper and lower blades of the mixing fan 110 may be employed in a different manner.

The material powder thus charged can be sterilized by the mixing fan 110 of the mixing cylinder 100 by contacting the ozone with a high concentration of ozone supplied from the ozone generator 200 to be described later.

The ozone generator 200 generates ozone and is basically composed of a cooler and an oxygen generator.

The amount of ozone generated by the ozone generator 200 is suitably about 1 to 30 g / hr based on the disinfection treatment of 100 kg of the plant powder, and 5 g / hr of the potato powder is best suited for the experiment of 100 kg of potato powder.

The air pump chamber 300 is located between the ozone generator 200 and the mixing cylinder 100 and collects ozone generated in the ozone generator 200 in a predetermined space to maintain a constant ozone concentration.

In order to prevent the ozone air and the powder from flowing backward from the mixing cylinder 100 to the ozone generator 200, the air pump chamber 300 is connected to the ozone generator 200 by the air pump The ozone is pushed in the direction of the mixing cylinder 100 at a high pressure through the injection duct 310 and supplied.

The ozone remover 400 is installed in an ozone (air) exhaust duct 130 of the mixing cylinder 100 located on the opposite side of the ozone injection duct 310 to remove ozone discharged from the mixing cylinder 100.

Here, the ozone remover 400 is preferably a heating pipe for removing (heating) ozone by heating the discharged ozone to 100 to 300 ° C.

The mixing tube 100 may further include a vibrator 500 mounted on the outer surface of the mixing tube 100 to generate vibration in the mixing tube 100. The mixing tube 100 may have a structure in which powder is adhered to the inner wall surface and the ceiling, Remove any powder that is not present.

The vibrator 500 may be mounted on the outer surface of the mixing cylinder 100 so as to cover the mixing cylinder lid 120 and the side of the mixing cylinder lid 120 using a plurality of vibration motors which can be used for a long time within 4000 rpm, for example.

The controller panel 600 includes a control circuit built in a monitor touch method to control ON / OFF, speed, temperature, and temperature of the mixing fan 110, the ozone generator 200, the air pump, the ozone remover 400, The amount of ozone, and the like.

3 is a perspective view showing a powder type food sterilizing apparatus using ozone according to another embodiment of the present invention.

Meanwhile, in the powder type food sterilizing apparatus using ozone according to another embodiment of the present invention, only a plurality of mixing cylinders 100 connected to the motor unit 50 can be connected and used. The ozone generator 200, The vibrator 500, and the controller panel 600 are configured in the same manner as in the above embodiment.

At this time, the ozone remover (400) for removing ozone, which is connected in series by the connecting duct (140) and discharged from the last mixing cylinder (100) only in the last mixing cylinder do.

This is because the ozone loss of the ozone air used for powder sterilization is not 10%, and more than 90% of the ozone is discarded through the ozone remover 400. As in the above embodiment, It is possible to sterilize various kinds of powders by the number of the added mixing cylinders 100 and the throughput to be processed at one time can be increased by the number of the connected mixing cylinders 100.
