According to one survey, 76% of the freshly pickled produce is lettuce, and in addition to salad lettuce, cabbage, carrots, celery, The market for other vegetables such as onions, broccoli, etc. is rapidly increasing.

Various techniques for reducing the number of microorganisms have been developed and applied in order to secure quality in processing fresh-cut agricul- tural food products. However, since most of them are applied with cleaning technology using chlorine water, problems of residues are raised and pin holes Problems such as development and poor sealing are occurring.

On the other hand, it is difficult to apply the processing, packaging and distribution methods of fresh-cut agricul- tural products in advanced countries to Korean market where the types and consumption behavior of agricul- tural products are different. Therefore, .

Therefore, there is a need for a pretreatment device for agro-food products that inhibits microorganisms present in fresh-cut agricultural products without using a disinfecting disinfectant and suppresses browning as well as slows down the rate of rash and texture.

The matters described in the background section are intended to enhance the understanding of the background of the invention and may include matters not previously known to those skilled in the art.

Referring to Fig. 1, the apparatus 1 for pretreating fresh grain cut greens according to the first embodiment of the present invention includes a heat treatment unit 10, a cooling unit 20, and a vibration drying unit 30.

The heat treatment unit 10 performs heat treatment by immersing the wire-cutting foodstuffs put in the washing net S into hot water.

Here, the cleaning net S is a container having a plurality of holes formed in a cubic shape and smoothly flowing hot water, carbonated water, and the like, which will be described later, over the entire surface. The shape of the holes is circular or polygonal, .

Hereinafter, the above-mentioned heat treatment unit will be described in more detail.

Referring to FIG. 2, the heat treatment unit 10 includes a hot water storage case 11, a hot water supply tank 12, and a hot water bubble generator 13.

On the other hand, the cooling unit 20 rapidly quenches the fresh-cut agricul- tured product heat-treated through the heat treatment unit 10 by immersing it in carbonated water (CW).

Hereinafter, the cooling unit 20 will be described in more detail.

Referring to FIG. 3, the cooling unit 20 includes a carbonated water storage case 21, a carbon dioxide storage tank 22, and a carbon dioxide gas bubble generator 23.

The carbonated water storage case 21 stores carbonated water CW through a carbonated water storage space 24 formed therein and stores the carbonated water CW stored therein in a state where the heat treated fresh edible agricultural product is introduced into the cleaning net S, .

The carbonated water storage case 21 is provided at one side with a carbonated water discharge passage 25 for discharging carbonated water (CW) stored therein. At this time, a carbonated water discharge flow rate control valve 25a for controlling the discharge amount of the carbonated water (CW) to be discharged is provided on the carbonated water discharge flow passage 25.

The carbonated water discharge flow rate control valve 25a may be constituted by an on / off type solenoid valve, but is not limited thereto, and may be applied as long as it can control the opening and closing of the sparkling water discharge flow passage 25 by an electronic actuator This is possible.

The carbonic acid gas storage tank 22 is installed at one side of the carbonated water storage case 21 and supplies carbonic acid gas to the carbonated water CW in the carbonated water storage case 21 through the carbonic acid gas supply channel 26 .

At this time, a carbonic acid gas supply flow rate control valve 26a for controlling the supply amount of the carbonic acid gas supplied from the carbonic acid gas storage tank 22 is provided on the carbonic acid gas supply passage 26.

The carbonic acid gas supply flow rate control valve 26a may be constituted by an on / off type solenoid valve. However, the present invention is not limited thereto. .

Meanwhile, the carbonic acid gas supply passage 26 may further include a bypass passage 27.

The bypass channel 27 is branched from the carbonic acid gas supply channel 26 and connected to the carbonated water storage case 21 on the opposite side from which the carbonic acid gas supply channel 26 is connected to the carbonated water storage case 21, A bypass valve 27a is provided for controlling the supply of the gas.

The bypass flow path 27 can double the supply of the carbonic acid gas supplied from the carbonic acid gas storage tank 22 to the carbonated water storage case 21 and supply the carbonic acid gas from both sides of the carbonated water storage case 21 The carbonic acid gas can be supplied to the carbonated water (CW) in a uniform distribution.

The carbonic acid gas bubble generator 23 is installed inside the carbonated water storage case 21 to generate bubbles on the side of the cleaning net S to be immersed.

In addition, when using carbonated water (CW) in which carbon dioxide gas bubbles are generated, it is possible to more easily induce deformation of the microbial cell membrane as compared with water in which carbon dioxide gas is dissolved, more effectively inhibit browning, This is not easy.

Here, the carbonic acid gas bubble generator 23 is the same technology as a well-known bubble generator widely used in the art, so a detailed description thereof will be omitted.

According to the cooling unit 20 having such a configuration, first, the heat-treated fresh-cut agricultural products are immersed in carbonated water (CW) in a short period of time. At this time, the time required for the heat-treated fresh-cut agricultural product to be immersed in carbonated water (CW) is 20 seconds or less, preferably 0.1 second to 10 seconds after the heat treatment.

More preferably between 0.1 seconds and 5 seconds, and the heat-treated fresh-cut agricultural products can not easily be repelled and browning can be suppressed unless they are immersed in carbonated water (CW) within the above-mentioned period of time and quenched.

At this time, the pH of the microbial cells on the surface is lowered and the microbial cell membrane is deformed, and the growth of microorganisms is suppressed by contacting the fresh-cut agrarian product immersed in carbonated water (CW) with the carbon dioxide gas bubbles dissolved in the carbonated water (CW) .

In addition, browning of the cut surface is inhibited by the inactivation of the browning enzyme by the contact with the carbon dioxide gas in the fresh-cut agrarian product.

This carbonated water (CW) dissolves carbon dioxide (carbon dioxide gas) in water at 1 ° C to 5 ° C and bubbles of carbon dioxide gas are continuously generated. At this time, the carbonic acid gas concentration of the carbonated water (CW) varies depending on the kind of the fresh-cut agricultural product, but is preferably 1000 ppm to 12000 ppm, more preferably 1000 ppm to 7000 ppm.

Depending on the type of crop, it is necessary to increase or decrease the concentration depending on the crops to be applied, because the occurrence of damages due to the carbonic acid concentration and the resistance to quality vary.

For example, the concentration of carbon dioxide gas increases in proportion to the concentration of 3000 ppm, 5000 ppm, and 7000 ppm when the fresh-cut agro-food product is young leaf vegetables and romaine.

When the concentration of the carbonic acid gas is less than the lower limit value, deformation of the cell membrane can not be induced by the carbon dioxide gas. If the concentration is above the upper limit, the functionality of the fresh-cut agrichemical product may be deteriorated.

Further, when the temperature of the carbonated water (CW) is out of the range of 1 占 폚 to 5 占 폚, the physical properties and taste of the fresh-cut agrichemical product may be deteriorated.

The time during which the fresh-cut agrichemical product is immersed in carbonated water (CW) is immersed in carbonated water (CW) for 100 seconds to 200 seconds, preferably 120 seconds to 170 seconds.

If the immersion time is less than the lower limit, the deformation of the microbial cell membrane can not be induced by the carbon dioxide gas. If the immersion time is above the upper limit, the freshness and the sensibility of the fresh-cut agrarian product may be deteriorated.

Accordingly, since the cold gas of carbon dioxide gas and the fresh-cut agrarian product are in contact with each other, browning and rash of the cut surface of the fresh-cut agrarian product are suppressed.

At this time, the cleaning net S is vibrated up / down, left / right, and vortex air is sprayed into the washing net S, so that the carbon dioxide gas cooling air is evenly contacted to all sides of the fresh-

On the other hand, the dry ice 49 may be used in an amount of 0.1 g to 3 g, preferably 0.5 g to 2 g, per 100 g of the fresh sliced agricultural product.

In addition, when the content of dry ice is less than the lower limit, the treatment effect is weak. When the content exceeds the upper limit, freezing of the fresh-cut agrichemical product and high-concentration carbon dioxide damage may occur and the abundance may be lowered.

Further, the carbon dioxide gas cool air is continuously or intermittently supplied to the fresh-cut agrarian food product for 150 seconds to 400 seconds, preferably 200 seconds to 400 seconds.

This is to adjust the surface temperature of the fresh-cut agrarian product to 1 ° C to 5 ° C. If the surface temperature of the fresh-cut agrarian food product is less than the lower limit value, low temperature disruption may occur and the functionality may be lowered. If the surface temperature is higher than the upper limit value, quality deterioration due to respiration and increase in microbial growth may occur.

On the other hand, the moisture discharged onto the inner drying space 48 of the drying case 41 is drained to the outside through the second water drainage path 41b provided on one side of the drying case 41 when a predetermined amount is collected.
