Description
본 발명은 농산물 세척 방법에 관한 것으로, 보다 상세하게는 과일, 채소류와 같은 농산물의 표면에 묻어 있는 먼지, 흙, 농약 등과 같은 오염물질을 효과적으로 제거할 수 있는 세척 방법에 관한 것이다.The present invention relates to a method for washing agricultural products, and more particularly, to a washing method that can effectively remove contaminants such as dirt, soil, pesticides, etc. deposited on the surface of agricultural products such as fruits and vegetables.
과일 및 채소류, 특히 근채류 등은 재배시 먼지, 흙, 농약 및 기타 오염 물질이 부착 또는 잔류하게 된다. 이러한 농산물의 오염 물질은 상품성을 높이기 위하여 유통 단계 이전에 표면 세척 처리를 하게 된다.Fruits and vegetables, especially root vegetables, will be attached or remain with dirt, soil, pesticides and other contaminants during cultivation. The contaminants of these agricultural products are subjected to surface cleaning prior to the distribution stage in order to increase the marketability.
특히, 과일의 꼭지 및 꽃받침 부위와, 근채류의 표면, 특히 장기 재배에 따른 토양 등이 견고히 부착되어 있는 것들과 도라지, 더덕 등과 같이 주근과 지근의 분지 부위 등에 부착된 오염 물질은 제거하기가 곤란하기 때문에 그대로 유통되고 있다. 이와 같이 오염 물질이 부착된 채로 유통되게 되면, 생산자 측면에서 판매시에 낮은 품질로 평가됨에 따라 경제적 손실이 발생하게 되고, 소비자 측면에서 농산물의 위생 및 품질에 관한 불만 요인을 발생하게 된다. 또한, 농산물에 부착된 오염물질 중에는 부패 미생물 등이 많이 존재하기 때문에 저장 및/또는 유통 중에 미생물 번식으로 인한 상품 손실의 우려가 있다.In particular, it is difficult to remove the contaminants attached to the stem and calyx of the fruit, the surface of root vegetables, especially the soil due to long-term cultivation, and the contaminants attached to the branch of the roots and roots, such as bellflower and deodeok. It is being distributed as it is. If the pollutant is distributed in this manner, it is economically lost due to the low quality at the time of sale from the producer side, and the dissatisfaction factor regarding the hygiene and quality of agricultural products from the consumer side. In addition, since there are many decaying microorganisms among the contaminants attached to agricultural products, there is a fear of product loss due to microbial propagation during storage and / or distribution.
이와 같은 농산물에 부착된 오염물질을 제거하기 위하여, 종래에는 물을 분사하거나 물에 세제를 혼합하여 분사하는 방법이 사용되었다. 그러나 이와 같이 물 또는 세제가 혼합된 물을 분사하는 것은 수작업에 의존하여 시행되기 때문에, 세척 속도나 효율이 낮은 문제가 있다.In order to remove contaminants attached to such agricultural products, a method of spraying water or mixing detergents with water has been conventionally used. However, since spraying water or water mixed with a detergent is carried out depending on manual labor, there is a problem of low washing speed or efficiency.
이와 같은 긴 세척 속도와 낮은 효율을 개선하기 위하여, 회전하는 솔을 이용한 기계적 세척 방법이 제안되었다. 그러나 이와 같은 기계식 솔을 이용하는 경우에, 솔과의 마찰 또는 기계의 운동 강도 등에 의해 농산물의 표면이 손상되어 상품성이 떨어지거나, 농산물의 신선도가 저하되는 문제가 상존하고 있다.In order to improve such a long cleaning speed and low efficiency, a mechanical cleaning method using a rotating brush has been proposed. However, in the case of using such a mechanical brush, there is a problem that the surface of the agricultural product is damaged due to friction with the brush or the kinetic strength of the machine, resulting in poor commerciality or lowering the freshness of the agricultural product.
본 발명은 전술된 종래 기술에 따른 문제점을 해결하기 위하여 도출된 것으로, 세척 속도가 높고 효율이 높으면서도 농산물을 손상시키지 않는 세척 방법의 제공을 그 목적으로 한다.The present invention has been made to solve the problems according to the prior art described above, and an object thereof is to provide a washing method having high washing speed and high efficiency while not damaging agricultural products.
전술된 목적을 달성하기 위하여, 본 발명에 따른 미립소자를 이용한 농산물 세척 방법은, 25~200메쉬의 입자 크기를 갖는 제올라이트를 주 성분으로 하는 세제가 0.5~7%로 분산된 세척수를 3~12㎏/㎠의 압력으로 10~30초간 분사하는 것을 특징으로 한다.In order to achieve the above object, the agricultural product washing method using the microparticles according to the present invention, 3 to 12 washing water in which a detergent based on zeolite having a particle size of 25 to 200 mesh is dispersed in 0.5 to 7% It is characterized by spraying for 10-30 seconds at a pressure of kg / ㎠.
여기서, 전술된 세제는 25~200메쉬의 입자 크기를 갖는 셀라이트, 실리카, 활성백토, 고령토 및/또는 백령토를 추가로 포함하여 구성되는 것을 특징으로 한 다.Here, the detergent described above is characterized in that it further comprises a celite, silica, activated clay, kaolin and / or kaolin having a particle size of 25 ~ 200 mesh.

In addition, the particle size of the materials constituting the detergent is preferably 25 to 200 mesh.
