Food-safety vegetable/fruit cleansing process comprising five stages in which staining and residues of agricultural chemicals are removed from surfaces of vegetables and fruits to achieve an effect of safety and sanitary of food
The present invention provides a food-safety vegetable/fruit cleansing process, which is a process applicable to washing vegetables/fruits of a medium or large quantity. The process includes five processing stages. The first stage is to flush and rinse a predetermined amount of vegetables/fruits in a clean water flow apparatus to carry out primary apparent surface treatment. The second stage is to place the vegetables/fruits in clear water, add a calcium ion solution and irradiate with an ultraviolet light for sterilization, and treat stains on the surface of the vegetables/fruits by applying an oscillator device that generate ultrasonic vibration so as to carry out secondary apparent surface treatment. The third stage is to place the vegetables/fruits in a water flow in which ozone (O3) is added to carry out primary aeration (oxidation) treatment in order to neutralize and remove agricultural chemicals remaining on the surface of the vegetables/fruits. The fourth stage is to carry out secondary ultraviolet sterilization on the vegetables/fruits under a water flow mode in which the vegetable/fruits are in reverse osmosis filtered pure water, and add a calcium ion solution in the water flow in order to carry out secondary aeration of the final residues of agricultural chemicals to achieve an effect of complete removal of the agricultural chemicals. The fifth stage is to subject the vegetables/fruits to centrifugal or horizontal position-shifting dehydration so as to complete the vegetable/fruit cleansing process to obtain food-safety vegetables/fruits which are effectively cleaned. With such a cleansing process, the vegetables/fruit could be made to meet the highest standard of safety and sanitary of food.本發明係提供一種食安蔬果清淨程序,係一種較適用於中、大量蔬果清洗的程序,該程序為五個處理階段,第一階段是將一定量的蔬果置於乾淨的水流設備下沖洗,以進行首次表面顯性處理,第二階段是將蔬果置於清水中,添加鈣離子溶液及紫外線燈進行照射殺菌,並利用振盪子設備產生超音波振盪蔬果表面的污漬,以進行二次表面顯性處理,第三階段是將蔬果置於加有臭氧(O3)的水流中進行首次氣曝(氧化)處理,以中合並去除蔬果表面殘餘農藥,第四階段是讓蔬果在讓蔬果在RO過濾純水之水流模式下,同時加入第二次紫外線殺菌,並於水流中添加鈣離子溶液,以達到最後剩餘農藥第二次
