Description

{FOODS STERILIZER}

The present invention relates to a food sterilizing apparatus, and more particularly, to a food sterilizing apparatus for sterilizing foods containing foods, for example, red peppers (including powdered red peppers or tongs) and various cereals, Dropping-high-pressure steam sterilization-discharging operation in which a high-pressure steam is momentarily sprayed on the dripped food to sterilize and discharge the dripped food to a sterilization tank, and a series of sterilization operations are continuously and repeatedly performed, And a separate steam is sprayed to the portion where the food is dropped at regular intervals.

Generally, in the case of food, sterilization must be performed as regulations are strengthened internationally. Conventionally, radiation sterilization has been mainly used for the sterilization of such food materials. However, there is a tendency that the consumer tends to reluctant to radiation sterilized foods, A device has been introduced that allows sterilization to proceed while continuing the high temperature sterilization path.

Many drying and sterilizing apparatuses using microwaves have been introduced in various examples of food sterilizing apparatuses. In the drying and sterilizing apparatuses using microwaves, microwaves penetrate instantaneously into the drying object, Since the heat is generated by the kinetic energy, the time required for heat conduction is significantly shortened, and high-speed heating is possible.

In addition, since the object to be dried serves as a heating element, there is no loss due to heating of the surrounding air or the heating device, so that a high thermal efficiency can be obtained. By using a microwave having a high speed response characteristic that propagates at a light velocity, instantaneous start, The temperature of the object to be dried can be easily controlled and the object to be dried can be relatively uniformly heated even in a complicated shape. Since the object is heated by the dielectric loss, It is possible to selectively heat only the necessary parts, and the control and use of the apparatus is simple, which is advantageous for industrial use.

However, since sterilization and drying using microwaves among the conventional food sterilization apparatuses use microwaves of several hundreds of watt or more, it is known that they can adversely affect the living body upon overexposure to strong microwaves. Specifically, Central nervous system disorders, headache, cancer, etc., and each country is strengthening regulations on various electromagnetic waves including microwaves.

Accordingly, despite the various advantages as described above, the microwave drying method seriously raises a problem of efficiency deterioration inevitably accompanied by the microwave leakage and reflected wave problem and the adoption of a batch type or intermittent type sealing structure for preventing the microwave leakage and reflected wave problem Has been pointed out as a major drawback.

In order to solve such microwave leakage and reflected wave problem and non-continuity of drying process, Korean Patent Registration No. 10-0414935 (drying device), Korean Patent Registration No. 10-0344569 (agricultural product dryer), Korean Patent Registration No. 10-0306617 Korean Patent No. 10-0216341 (Organic matter treatment method and apparatus), Korean Patent Laid-Open No. 10-2004-0061441 (Microwave continuous drying apparatus), Korean Patent Laid-Open No. 10-2003-0037759 (raw soybean powder manufacturing apparatus) , Japanese Utility Model Registration No. 0359559 (Continuous Drying Apparatus), Japanese Patent Laid-Open No. 2004-71520 (Microwave Induction Heating Apparatus), Japanese Patent Laid-Open No. 2003-21460 (Organic Material Drying Apparatus), Japanese Patent Registration No. 2514231 Japanese Unexamined Patent Publication No. 2000-245420 (Continuous Drying Apparatus), Japanese Patent Application Laid-Open No. 2001-330369 (Microwave leakage preventing structure of a microwave rotary dryer), U.S. Patent No. 6,444 U.S. Patent No. 6,122,831 (Chemical Drying Process), U.S. Patent No. 5,869,816 (Continuous Processing Device and Method of Granule), U.S. Patent No. 6,344,638b1 (Continuous Sterilization Method of Medical Waste) U.S. Patent No. 4,762,484 (Continuous Drying and Recycling of Waste Rubber), PCT Patent Application No. 97/36140 (Granulating Process), U.S. Patent No. 5,400,524 (Granule Continuous Treatment Facility), U.S. Patent Registration No. 5,037,560 Various attempts have been made to use a multi-stage choke connection, a conductive sealing material, an attenuation tunnel, a water trap, and an aluminum curtain.

However, such food sterilization and drying apparatuses are intermittent in the process of product disinfection, and thus have a problem of low work efficiency, high processing cost, inadequate control of the object to be treated and large amount of product processing, low energy efficiency, There is a problem in sterilization and moisture retention for food.

On the other hand, in the case of a food sterilizing apparatus that allows sterilization to be carried out while conveying food through a conveyance path (e.g., a conveying screw) having a certain length (relatively long length), the food is exposed to high temperatures , There is a problem that the moisture present in the food itself evaporates and the original ingredient and taste are changed (a problem of deterioration).

Particularly, in the case of a food sterilizing apparatus, the food becomes roasted through a sterilization path at a high temperature, so that fermentation can not be performed. In this case, for example, kimchi is not fermented when the kimchi is immersed.

In recent years, sterilization is performed using a high-temperature steam sterilizer in order to solve the above problems. The high-temperature steam sterilizer sufficiently exerts a germicidal effect to achieve an effective sterilization operation, but it performs high-temperature steam sterilization while feeding food continuously through a relatively long feeding path (sterilization with high temperature and pressure for a long time There is a problem that the surface of the food changes (the hue of the original food changes), or the food itself deteriorates.

In some cases, in the case of food sterilization by hot steam injection, steam may not adhere to the food during the process of matching the high temperature steam and the food, and steam and food may move separately. In this case, There is a problem in that it is burned by the high temperature or is not properly sterilized.

On the other hand, the heat transfer sterilizing and drying method using hot air or heat in the food sterilizing and drying apparatus has a disadvantage in that the heating speed is slow and the temperature control is not easy and the heat loss is large and the quality of the sterilized dried product is not uniform.

The present invention relates to a food sterilizing apparatus for sterilizing foods containing pepper (basically including powdered red pepper or tender pepper) and various grains. The food sterilizing apparatus continuously quantitatively feeds food into a sterilization tank, A series of sterilization operations consisting of injection-dropping-high-pressure steam sterilization-discharge for instantly spraying and sterilizing the steam is carried out continuously and repeatedly, while steam is applied to the portion where the food is dropped at regular intervals The present invention provides a food sterilizing apparatus which is adapted to inject the food into the food sterilizing apparatus.
