The pretreatment for freshness of bellflower and deodeok was performed using the pretreatment apparatus and the pretreatment method according to the present invention. In particular, this experiment was carried out by varying the washing water pressure, the moving speed of the transfer belt, the reciprocating speed of the nozzle in order to set the optimum conditions for the cleaning and peeling of the bellflower and deodeok. Table 1 and Table 2 below show the experimental conditions of bellflower and deodeok, respectively. In particular, the washing water pressure described in the table below means the pressure of the washing water sprayed from the front second nozzle unit-rear second nozzle unit-front third nozzle unit, and in this experiment, the rear third nozzle unit was not used.

-Weight change

The weight change was measured by comparing the weight values of the bellflower and the duck before and after pretreatment. 9 (a) and 9 (b) are graphs showing the weight loss rates of bellflower and deodeok, respectively. In the case of bellflower, the weight loss rate was about 3.9 ~ 5.7% under condition W4, and the weight loss rate was about 1.7 ~ 3.7% under condition W4.

-Washing degree change

The change of washability is measured by measuring the color of the surface of the initial raw material with L (+ Lightness), a (+ Redness, -Greenness, b (+ Yellowness, -Blueness), and then the ΔE value is expressed as shown below. The degree of wash was set by calculation.

10 (a) and 10 (b) are graphs showing the degree of washing of bellflower and deodeok, respectively. When the preferred washing degree was set to 30 (ΔE) (washing rate of about 95%) or more, it was judged to be excellent because the washing degree was measured as 30.08 (ΔE) under condition W4. 34.74 (ΔE) was found to be excellent.

Wound rate

The wound rate was calculated by substituting the number of wounds before and after pretreatment using the same bellflower and deodeok by substituting the following equation.

Wound Rate (%) = Number of Wounds / Total Number of Pretreatments × 100

Table 3 below is a table showing the wound rate of bellflower. In the case of bellflower, washing and peeling were excellent without a wound rate under condition W4. In addition, deodeok was not injured in all conditions.

Using the pretreatment apparatus and method according to the invention it was confirmed through experiments that the pretreatment can be performed more efficiently while reducing the weight change of the columnar root vegetables, increase the degree of cleaning and lower the wound rate.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
