Kimchi is a representative Korean traditional food. It is made by mixing salted vegetables with various seasonings. During the ripening process, fermentation progresses through the action of microorganisms, and various organic acids and substances that promote health-beneficial physiological activity are produced, thereby preserving the natural properties of the raw materials. It is a food with excellent taste and nutritional value, with complex characteristics that are harmoniously combined with each other. Kimchi has been manufactured and consumed historically for a long time. In the past, it was mainly consumed in the form of self-manufacturing at home, but recently, due to the nuclear family, increase in the industrially active population, and changes in lifestyle, kimchi has been produced commercially. The market is gradually increasing. Accordingly, much research is being conducted on the technology for mass production of kimchi and the scientificization of kimchi's essential characteristics, and the number of commercial production facilities is increasing. However, the uniformity of quality and production process are affected by quality deviations due to the origin of raw materials and seasonal characteristics. In terms of standardization, much research is still needed. In particular, the quality of agricultural raw materials varies greatly depending on the season or environmental factors, the price fluctuates widely depending on the crop, and standardization to ensure uniform quality of products is difficult due to the labor-intensive production process. In addition, scattered problems such as deterioration of the business environment of manufacturers due to the burden of high production costs act as a burden to the development of the kimchi industry. Therefore, for the globalization of kimchi, Korea's representative traditional food, much research is needed on stabilizing the quality and price of raw materials, improving productivity through standardization and process optimization of the manufacturing process, and uniformizing the quality of the finished product produced.

The main method of making kimchi consists of the process of pickling the main ingredients, mixing various auxiliary ingredients to produce seasoning, mixing the pickled main ingredients with the auxiliary seasoning, and maturing the finished kimchi. Among kimchi manufacturing methods, many research and development results related to seasoning manufacturing and microbial ripening of kimchi have been reported in various ways, but there are relatively few standardization and advanced technical achievements in pickling, which is the most important part in commercial mass production. .

In the kimchi manufacturing process, the pickling process uses the osmotic pressure principle of salt to allow salt to penetrate into the tissue of vegetables or cabbage, allowing them to be pickled at a certain salinity, thereby improving the taste, eliminating the green smell unique to vegetables, and making the tissue flexible for seasoning mixing. It facilitates the growth of lactic acid bacteria and provides an environment suitable for the growth of lactic acid bacteria. In addition, the pickling process is a factor that directly affects the quality of kimchi. During mass production, salinity variation between cabbages must be minimized to maintain consistent pickled quality, and to improve productivity, the pickling time, which usually takes 8 to 24 hours, must be shortened. It is essential.

In general, most kimchi manufacturers produce kimchi using a pickling process based on the salt water pickling method, which uses brine (salt water) to pickle large amounts of cabbage, reducing pickling variation between individuals and various agricultural products including cabbage (e.g., radish). , young radish, etc.) because it has the advantage of being versatile in pickling.

However, the pickling process based on the conventional salt water pickling method requires a long pickling time and a large amount of salt compared to the dry salt pickling method, which uses salt directly on agricultural products as raw materials to pickle them. In particular, the cost burden on kimchi manufacturers increases due to the rise in the cost of salt as the domestic salt farm area rapidly decreases, and a large amount of pickling water used in the pickling process is treated as wastewater, so there is a problem of high pickling water treatment costs. .

It includes a process (S500), a dehydration process (S600), a mixing process (S700), a filling process (S800), and a packaging process (S900).

First, cabbage, which is a raw material to be manufactured into kimchi, can be received in a kimchi manufacturing system using a means of transportation such as a vehicle (S100).

Afterwards, the kimchi manufacturing system automatically inserts the received cabbage into a cabbage core remover (not shown) in order to remove the cabbage core of the received cabbage, and the cabbage core remover separates the cabbage core from the automatically inserted cabbage. It can be removed (S200).

Afterwards, the kimchi manufacturing system automatically feeds the cabbage from which the cabbage core has been removed into a cutter (not shown) in order to trim the cabbage to suit the processing purpose, and the cutter cuts the cabbage from which the core has been removed into 1/2 or 2 pieces according to the processing purpose. Can be cut to 1/4 size (S300).

Afterwards, in order to remove foreign substances from the cabbage, the kimchi manufacturing system causes the cut cabbage to be washed with washing water sprayed from a washing water spray device (not shown), or the cut cabbage is washed with washing water stored in a tank (not shown). Foreign substances can be removed by inputting (S400).

Afterwards, in order to pickle the washed cabbage, the kimchi manufacturing system moves the washed cabbage to the salt spray-type kimchi pickling device 100 of the present invention, which will be described later, and pulverized cabbage sprayed from the salt spray-type kimchi pickling device 100. Let it be pickled with salt (S500).

Afterwards, the kimchi manufacturing system automatically feeds the pickled cabbage into a dehydrator (not shown) in order to dehydrate the washing water remaining in the pickled cabbage, and the dehydrator removes the washing water remaining in the pickled cabbage through a dehydration process. You can do it (S600).

Afterwards, the kimchi manufacturing system automatically feeds the dehydrated cabbage into a mixing machine (not shown) to mix the dehydrated cabbage with the seasoning. The mixing machine produces the kimchi seasoning for kimchi production and then inputs and dehydrates the dehydrated cabbage. Kimchi can be made by mixing the completed cabbage with kimchi seasoning (S700).

Afterwards, the kimchi manufacturing system can fill the kimchi produced in the mixing machine into a chamber (not shown) (S800).

Afterwards, the kimchi manufacturing system discharges a certain amount of kimchi filled in the chamber and automatically feeds it into the packaging machine, and the packaging machine can produce packaged kimchi by packaging the loaded kimchi (S900).

Thereafter, the mesh vibrator 130 applies the vibration of the vibrator 132a to the receiving surface 131 to cause the salt contained in the bottom surface of the receiving surface 131 to flow in multiple directions, so that the salt flows on the receiving surface 131. Salt is sprayed toward the conveyor belt 140 through a plurality of meshes 131a to 131f formed on the bottom (S525).

Meanwhile, before the salt is sprayed onto the conveyor belt 140, the cabbage from which foreign substances have been removed may be moved to the conveyor belt 140 through a separate moving means (S530).

Afterwards, the conveyor belt 140 can move the cabbage from which foreign substances have been removed from one side (S535).

In one embodiment, the process of spraying salt toward the conveyor belt 140 is preferably after the moving step (S535), and during this process, the salt may fall on the cabbage (S540).

Afterwards, the conveyor belt 140 can move the cabbage sprinkled with salt to the other side adjacent to the drum screen transfer device 150 (S545).

Afterwards, the cabbage sprinkled with salt is introduced into the drum 151 through the inlet of the drum 151, and the drum screen transfer device 150 can mix the cabbage and salt using the rotating blade 152. (S550).

Afterwards, the pickled cabbage produced by mixing cabbage and salt in the mixing step (S550) is discharged from the outlet of the drum 151 (S555), is input into the container carrier 160 along the inclined plate 153, and is then transferred to the container carrier. Through (160), it can be moved to the dehydration process (S600), which is a post-process of the pickling process (S500) (S560).

Comparative Example 1

In Comparative Example 1, an experiment was conducted comparing the dry salt pickling method and the salt water pickling method, which are the methods of the salt spray type kimchi pickling device 100 of the present invention, and the results of the experiment are shown in [Table 1] below.

division Brine pickling method (4% brine) Dry salt pickling method (4% dry salt) note Pickling time (hr) 8 hours 0.5hr Pickling time reduced by 1/16 Salt amount (g) 80g 40g Reduce salt amount by 1/2 wastewater volume 2 kg 100g Waste water volume reduced by 1/20

In Comparative Example 1, the time required to pickle raw cabbage into pickled cabbage (salinity 1.6%) was measured to be 8 hours (hr) for the salt water pickling method, while the dry salt pickling method was measured to be 0.5 hours, and from this, the dry salt pickling method was measured to be 0.5 hours in salt water. It was confirmed that the pickling time of cabbage was shortened by 1/16 compared to the pickling method.

In Comparative Example 1, the amount of salt used to pickle 1 kg of cabbage was 80 g for the salt water pickling method, while the amount of salt used for the dry salt pickling method was measured to be 40 g. This shows that the amount of salt used in the dry salt pickling method is compared to the salt water pickling method. It was confirmed that the amount was reduced by 1/2.

In Comparative Example 1, the wastewater produced after pickling 1 kg of cabbage was measured at 2 kg for the salt water pickling method, while the amount of wastewater generated for the dry salt pickling method was 100 g. This shows that the amount of waste water generated from the dry salt pickling method is 1/20 compared to the salt water pickling method. It was confirmed that this was reduced.

Comparative Example 2

In Comparative Example 2, an experiment was conducted to measure the salinity of pickled cabbage using the dry salt pickling method according to the salt amount (dry salt concentration) and pickling time, and the results of the experiment are as shown in FIG. 9.

Figure 9 is a graph showing the results of comparing the salinity of pickled cabbage with different dry salt concentrations.

The salt spray type kimchi pickling device 100 of the present invention is operated based on the dry salt pickling method, and as shown in the graph shown in FIG. 9, a small amount of salt is used compared to the salt water pickling method (dry salt concentration 2%, 4%, 8%). It was confirmed that the concentration of pickled cabbage can be easily adjusted to the user's desired concentration (%) even with a small pickling time.
