Description
本發明係提供一種應用於農畜牧產品之雷射清潔設備,尤指包括一雷射光源、一光學調整裝置及至少一待清潔物之雷射清潔設備,藉由前述構件來達到耗費成本低、工序少、作業時間短及清潔效果佳之清潔作業,且本發明為一種非接觸式的清潔方式,可減少間接污染問題。 The present invention provides a laser cleaning device applied to agricultural and livestock products, especially a laser cleaning device including a laser light source, an optical adjustment device, and at least one object to be cleaned. The aforementioned components achieve low cost, A cleaning operation with few procedures, short operation time and good cleaning effect, and the present invention is a non-contact cleaning method, which can reduce indirect pollution problems.
按,民以食為天,各個國家在發展工業科技之餘,亦必須建立起農業及畜牧業等之民生基業,方能確保國家的穩定成長。但由於環境污染、農藥的過度使用及人為添加非合法材料至食品中,故造成食品安全問題頻傳,而為了防制吃進食品對人體產生不良的影響,對食品做基本清潔是必須的,而一般清潔食品的常用做法為水洗或利用對人體無害的清潔劑進行清洗,藉以除去附著於食品表面的細菌、蟲卵、農藥殘留及穢物,前述清洗做法對於農畜牧業需要進行大量清洗而言,需要添購昂貴清洗設備及耗費大量水資源,同時清洗設備需佔據大量的空間,且清洗過後的食品需要進行瀝水及烘乾作業。況且以水柱沖洗食品表面時,若遇到附著力較強的附著物,即無法以一次作業即可清洗完成,必須重覆清洗程序加以清洗,如此便又耗費更多水資源及清洗時間,前述的清洗設備所需耗費成本較高、工序較多及作業時間較長皆為其缺點,而有待從事此行業者加 以改善。 According to the principle, food is the most important thing for the people. In addition to the development of industrial technology, all countries must also establish the people's livelihood foundation such as agriculture and animal husbandry to ensure the country's stable growth. However, due to environmental pollution, excessive use of pesticides, and artificial addition of illegal materials to food, food safety problems are frequently caused. In order to prevent the adverse effects of eating food on the human body, basic food cleaning is necessary. Generally, the common method of cleaning food is washing with water or using a detergent that is harmless to the human body to remove bacteria, insect eggs, pesticide residues and filth attached to the surface of the food. The aforementioned cleaning method is for the agriculture and animal husbandry industry to require a lot of cleaning. , It is necessary to purchase expensive cleaning equipment and consume a lot of water resources. At the same time, the cleaning equipment takes up a lot of space, and the cleaned food needs to be drained and dried. Moreover, when washing the food surface with a water jet, if it encounters strong adhesion attachments, it cannot be cleaned in one operation. It must be cleaned by repeating the cleaning procedure, which consumes more water resources and cleaning time. The high cost of cleaning equipment required, more procedures, and longer operation time are all disadvantages, and those in this industry need to increase improving.
故,發明人有鑑於上述習用之問題與缺失,乃搜集相關資料經由多方的評估及考量,並利用從事於此行業之多年研發經驗不斷的試作與修改,始有此種應用於農畜牧產品之雷射清潔設備發明專利誕生。 Therefore, in view of the above-mentioned conventional problems and deficiencies, the inventor collected relevant information through multiple evaluations and considerations, and used years of research and development experience in this industry to make continuous trials and modifications.
