The AD-4971 metal detector is a high-precision and high-performance metal detector introduced by Japan A&D Corporation after the acquisition of MY-TECH in Japan . It adopts 16bit high resolution ADC, high precision digital filtering technology and high precision signal processing method , and independent detection algorithm . It can realize that one AD-4971 detector can realize metal foreign matter using metal deoxidizer as preservative. determination. When the standard packaging weight of the metal deoxidizer is 1 g or more , the metal foreign matter of Fe Ф 0.3 mm and SUS Ф 0.8 mm can be detected . Japan MY-TECH Company ( also translated into Japan Meida Company ) is a company with more than 50 years of professional metal detector development and production. Since the launch of the *Taiwan metal detector in 1958 , the products have been sold all over the world . The common models on the market are : CS series () CS1-S250-CSP). CR series (CR-PK80-SHG), DR series (DR2) -PK70-SHG) and so on. In the food industry , the aquatic product processing industry has a high reputation. As a new material for food preservation, deoxidizer has its unique advantages. It is contained in the same container as the food, and the deoxidizer absorbs the oxygen in the container, so that the inside of the container is in an anaerobic state, and the food is preserved. However, the raw material of the deoxidizer must have side effects such as stable reaction, no strange smell and no harmful gas generation, and it is harmless to the human body in case of ingestion. Deoxidizers are generally based on iron powder and are used in general foods to maintain food quality and extend shelf life. Use in healthy foods to prevent oxidation of oils, prevent fading and maintain nutrients. Commonly used reaction principles for deoxidizers include iron oxide oxidation (iron), enzyme oxidation (enzyme), ascorbic acid oxidation, and photo-sensitive dye oxidation. Most of the deoxidizers currently in use are based on iron oxide oxidation reactions. This iron-based deoxidizer can be made into a bag and placed in a package to reduce the oxygen concentration to zero . 01% . Generally, lg iron powder can be reacted with 300 mL of oxygen. When used, the appropriate amount can be selected according to the amount of oxygen remaining after packaging and the oxygen permeability of the packaging film. Products used include confectionery, dried seafood snacks, cooked meat products, rice cakes, pasta, cheese, and dried vegetables. Since in Japan, cakes, cookies, seaweed, dried meat, dried fruit and other products use the metal as an oxygen scavenger preservative. In the 1990s, Japan implemented PL Law (Product Liability Law in Japan (Produet liability law referred PL)), food Manufacturers have added metal detectors , but the use of preservatives as metal deoxidizers has prompted many companies to use X- ray (X -ray ) detection methods to detect metal foreign objects in products . However, X- ray metal detectors are expensive. And long-term use will cause certain radiation damage to nearby staff . Therefore , Japan's A&D company now zui's new AD-4971 series metal detectors fill the low cost , no radiation The blank of the AD-4971 series uses the principle of electromagnetic induction to complete the A/D conversion technology and digital filtering technology of A&D, which realizes the detection of foreign matter for products using metal deoxidizer as preservative. may.
