Description

Plant for producing raw soybean powder by microwave dielectric heating drying {Plant unit of producing powder of soybean using microwave drier}

The present invention relates to an apparatus for producing raw soybean powder of microwave dielectric heating drying method, which eliminates problems caused by micropowderization of raw soybean, which is widely used as a food processing material for various uses, and an apparatus for manufacturing high-nutrition soybean powder. It is about the provision of.

Raw soybean powder is widely used as beverages, secondary processing ingredients and the like. This seems to be due to the increasing demand according to the recognition that raw soybean powder has a high digestive absorption rate and may be useful as a disease treatment aid for various uses. Activated raw soybean powder is also widely used as a raw material for a variety of food production.

However, the powdered raw soybeans are known in the industry as having the following problems.

(1) In pulverizing raw soybean, the powder refined by crushed frictional heat causes carbonization and also causes problems such as entanglement due to degeneration of valuable nutrients such as proteins and lipids and reduction of nutrients.

(2) It is also known that most of the hot air is blown to dry prior to powdering, which causes heat denaturation and nutrient destruction even when dried by the hot air. In particular, when drying at a low temperature, a characteristic fishy smell occurs, which makes it difficult to use as a processing material.

In order to solve this problem, various configurations have been devised from the prior art. As the configuration of the prior application, various methods for maintaining an appropriate drying temperature as steam heating have been devised in various ways, but such a steam heating method needs to increase the heating time and thus does not solve the problem of thermal degeneration.

The conventional structure is characterized in that most processes go through the process of drying the raw soybean, the process of separating the peel and the cotyledons, the drying process, the grinding process, the redrying process, and the powdering process. There is not much, and each of the technical features is merely to dry in the process described above.

In recent years, such a drying method has been proposed, which is not a conventional hot air or steam heating method, for example, a drying method by far-infrared radiation.

In this method of drying by far-infrared radiation, it is laid long on the flow path of soy cotyledon of raw soybean to process the radiation plate emitting far-infrared rays to emit far-infrared rays to heat and dry by electromagnetic energy.

That is, as shown in Fig. 1, it consists of a tower shape standing up as part of the processing process of soybean powder, and has a far-infrared radiation mechanism (UV) and a heating mechanism (shape-shaped) on the flow path (F) of cotyledon or powder of fresh soybean. Drying is performed by disposing HT) on the entire flow path (F).

However, this far-infrared radiation method has the advantage of easy penetration into raw soybean due to the relatively long wavelength of infrared rays. However, the configuration of the whole radiation plate is very expensive and the temperature control over the length of the whole radiation plate is easy. Difficulty is said to have a major flaw. In addition, it takes a long time for the long wavelength of far-infrared rays to penetrate and act on the material to be dried, which also increases the processing time and the energy consumption.

In addition, the far-infrared radiation should be configured so that the heating means is wound around the heating coil to the various ceramics emitting far-infrared rays or the heating fluid passes therein. Difficulties in application are seen as difficult to apply. In addition, the apparatus for producing raw soybean powder by far-infrared radiation is not considered to be optimal for removal in fishy fish by a specific solubilizing enzyme.

The present invention has been made in view of the problems of the above-described conventional drying method, in particular, the process apparatus of the far-infrared heating method, and is mainly focused on improving the problem of the far-infrared drying method.

The manufacturing apparatus of the raw soybean powder of the microwave dielectric heating drying method of the present invention devised in view of the problems of the conventional structure described above, the drying and powdering of green soybean through the dielectric heating (dielectric) The present invention provides an apparatus for producing raw soybean powder of microwave dielectric heating and drying method which minimizes denaturation of powder and improves powder state by performing.

It characterized in that it further has a screw conveyor for feeding soybean powder dried.

Other features of the manufacturing apparatus of raw soybean powder of the microwave dielectric heating drying method of the present invention;

The dielectric heating unit is one or a plurality of drying devices disposed on the conveyor flow path and varies depending on the size and processing capacity of the equipment. The cotyledon of green soybeans flowing on the conveyor is provided with a magnetron and waveguide in a shield casing. And an apparatus for heating and drying the powder.

In addition, the flow path of the coarse powder of the coarse powder device and the excretion path of the dielectric heating unit is formed of a flow path consisting of a Z conveyor,

It is also a major feature of the present invention that the flow path of the fine powder device and the excretion path of the dielectric heating unit are formed as a flow path composed of a belt type horizontal conveyor.

The apparatus for producing raw soybean powder of the microwave dielectric heating drying method of the present invention together with the accompanying drawings will be described in more detail.

Fig. 1 is a schematic diagram of an equipment configuration showing one step in a conventional manufacturing apparatus of raw soybean powder of known prior art, and Fig. 2 is a microwave suitable for the construction of a manufacturing apparatus of raw soybean powder of the microwave dielectric heating drying method of the present invention. It is explanatory drawing explaining the wavelength characteristic of the.

The two most important problems in powdering raw soybean from the prior art which focused on devising this invention are as follows.

(1) First of all, it is the induction of fishy smell caused by oxidation by lipoxygenase, an oxidase in raw soybean, which is the biggest obstacle in processing processed soybean powder.

(2) Then, the degeneration of proteins, oxidation, and other useful nutrients caused by activation due to the increase in surface area due to the powdering of raw soybeans act as very disadvantageous aspects for secondary processing.

Therefore, the powdering of raw soybeans is the most important technical consideration point to minimize the occurrence of fishy smells and also to carry out the maintenance of nutrients.

In order to solve the above problems, the drying method of the raw soybean powder in the present invention is basically based on the dielectric heating method using a microwave, characterized in that the ozone processing method is further given for the removal of fishy smell.

The characteristics of the microwave (M) shown in Figure 2 is a radio wave with a wavelength of 10 ^-3 to 1m, the frequency is 30 Mhz-300Ghz, intermolecular by rotating the electrode electrode of the dielectric that does not flow a current while passing the radio waves It is a well-known heating method for heating with frictional heat.

The internal heating of drying by microwave and energy efficiency of up to 80%, almost no change in the physical properties of the object to be treated, and only the microwave generator is installed in a specific area without causing pollution by-products. In addition to this minimized advantage, it has the advantage of extremely simple maintenance.

In addition, it is possible to continuously dry the object to be dried for a short time, and thus it is seen as being most suitable for drying the object flowing on the conveyor.

The ozone sterilization method introduced to remove the characteristic fishy smell is to apply the sterilization and deodorizing power of ozone (O ₃ ), and utilizes the property of generating oxygen (Nascent Oxygen) by separation of the third atom having weak bonding in air. It is known to have 6 times stronger deodorizing power than chlorine.

Therefore, it is considered to be the most preferable as a deodorizing means for preventing fishy smell caused by the oxidation action of lipoxygenase in soybean and deodorizing without adversely affecting nutrients and other useful components.
