Experimental Example 1

When the foamed rubber composition was applied to the outlet of the food storage unit according to the present invention, a noise confirmation experiment was performed to confirm whether the noise reduction effect was exhibited.

A decibel meter was prepared and the noises before and after applying the foamed rubber composition to the outlet of the food storage were measured, respectively. The noise source and the decibel meter measured noise for 10 seconds with a gap of 50 cm. The results are shown in Table 1 below.

Before applying foam rubber composition After applying foam rubber composition Measurement decibel (dB) 82.0 30.5 Noise reduction - -37.2%

As described above, after applying the foamed rubber composition according to an embodiment, the noise was reduced by about 37%, and the noise reduction effect appeared. Therefore, by applying the foam rubber composition to the outlet of the food storage, it is possible to reduce the noise to feed the animals without surprise.

Experimental Example 2

According to the present invention, when the non-slip pad is attached to the food supply, a work efficiency evaluation experiment was performed to confirm whether the food supply efficiency is improved. First, the food was supplied 20 times using the non-slip pad-feeding unit, and then the food was supplied 20 times using the non-slip pad-feeding unit. The number of times the food slipped is shown in Table 2 below.

Feeding frequency (times) Slips (times) Pad × 20 5 Pad ○ 20 0

As described above, the number of times the food slipped before reaching the target point out of the 20 feedings to the food supply unit without the non-slip pad was 5 times, and the food supply unit with the non-slip pad was fed. The food never slipped for 20 times. Therefore, by attaching an anti-slip pad to the food supply, it is possible to accurately feed the target livestock without slipping even in the operation of the smooth food supply.

Experimental Example 3

In order to confirm the antimicrobial effect of the antimicrobial coating layer according to the present invention, the microbial detection experiment of the antimicrobial coating layer composition (Example, Comparative Example 1, Comparative Example 2, Comparative Example 3) prepared by the above process was performed. Bacterial detection tests were performed on a sterile workbench and dry film medium for Staphylococcus aureus was used.

First, 9 mL of sterile water was added to 1 g of the antimicrobial coating layer composition to make a 10-fold dilution solution evenly mixed using a homogenizer. Transfer the sample dilution solution to the sterile test tube and inoculate S. aureus to 3.0 × 10 ² CFU / mL concentration and mix using Voltex Mixer. Inoculate 1 mL of the finished sample solution into the dry film medium, transfer to an incubator, and incubate at 35 ° C. for 48 hours. After 48 hours, the number of colonies formed on the dry film medium was read to calculate the rate of change of the number of bacteria. The results are shown in Table 4 below.

Example Comparative Example 1 Comparative Example 2 Comparative Example 3 Gun powder 5.7 3.6 7.1 5 Cudrania Extract 2.3 1.4 2.9 3 Antibacterial material

Rate of change -99% -44% -99% -99%

As described above, in Comparative Example 1, although the concentration was lower than the inoculated bacterial concentration, Staphylococcus aureus remained, and in Example, Comparative Example 2 and Comparative Example 3, the bacteria were almost removed. However, in the case of Comparative Example 2, the amount of the antimicrobial material added during the film production was not uniformly mixed, but the surface of the film was roughly manufactured, which was not suitable for application. There is a problem that is not uniformly melted during the processing of some antimicrobial coating layer. Therefore, the antimicrobial coating layer according to the present invention is suitable for application and exhibits an antimicrobial effect in food storage.
