According to a preferred embodiment of the present invention, the sterilant supplied by the sterilant supply module 260 may use a mixture including sodium chlorite, citric acid and sodium bicarbonate.

Looking specifically at the disinfectant, sodium chlorite (NaClO ₂ ) reacts with citric acid to generate chlorin dioxide (ClO ₂ ) gas.

Chlorine dioxide is a material with excellent sterilizing power but weaker oxidizing power than chlorine. It does not generate carcinogens due to its low reactivity with organic matter, has weak metal corrosiveness, and plays a role in decomposing odorous components such as ammonia, hydrogen sulfide, and methyl mercaptan. do In particular, chlorine dioxide does not cause sensory damage to food, so it not only effectively prevents spoilage of rice cakes when it remains in water for a long time, but also removes odors remaining in discharged water and maintains the freshness of rice cake products for a long time, making it a disinfectant. can be used effectively. However, since chlorine dioxide has a small amount of effective chlorine dioxide (ClO ₂ ) in water and exists in the form of chlorine (Cl ₂ ), there is a problem that sterilization and deodorization are low. However, sodium chlorite and citric acid are highly reactive and generate chlorine dioxide gas in a short time, making it difficult to effectively sterilize the discharged water for a long time.

Accordingly, in the rice cake manufacturing system 10 according to the present invention, sodium bicarbonate (NaHCO ₃ ) is introduced into the sterilant supplied by the sterilant supply module 260 of the sterilization unit 250 so that sodium chlorite and citric acid are discharged The sterilization efficiency of the discharged water can be greatly improved by adjusting the reaction rate within the discharged water, thereby significantly inhibiting the growth of harmful microorganisms such as fungi and food poisoning bacteria in the discharged water, and reducing the number of repeated uses of the discharged water. can increase

Specifically, sodium bicarbonate reacts with hydrogen of citric acid to give a buffering effect that lowers the reaction rate with sodium chlorite, thereby reducing the reaction rate between citric acid and sodium chlorite, so that chlorine dioxide remains at low concentration for a long time. It plays a role in uniformly sterilizing the discharged water.

Accordingly, the sterilant supply module 260 includes a first sterilant composition including sodium chlorite, sodium bicarbonate and water (H ₂ O) and a second sterilant composition including citric acid and water (H ₂ O) as sterilants.

One having a structure including a jaw 265 may be introduced. The sterilant mixing tank 265 is connected to the sterilization chamber 251 through a connecting pipe to supply the sterilant, and the sodium chlorite contained in the sterilant reacts with citric acid to generate activated chlorine dioxide, and the generated chlorine dioxide is discharged. It exhibits a sterilizing effect by removing microorganisms and odorous components contained in the water, and can effectively sterilize the water for a long time by remaining in the water for 20 to 60 minutes. When sodium chlorite and citric acid are reacted, the residence time is significantly increased compared to the time chlorine dioxide remains in the discharge water for 10 to 20 minutes, and thus the amount of sodium chlorite and citric acid used can be greatly reduced.

To this end, the first disinfectant composition may use a mixture containing 30 parts by weight of sodium chlorite, 50% by weight of sodium bicarbonate and 20% by weight of water, and the second disinfectant composition includes 50% by weight of citric acid and 50% by weight of water. A mixture may be used, and the first disinfectant composition and the second disinfectant composition may be mixed in a weight ratio of 2:1 to 1:2 to prepare a disinfectant, and the prepared disinfectant may be mixed with the discharge water at a weight ratio of 1:10 to 1:10,000.
