High Dream gravity metal detector|The "Inspector" on the food processing line


There are many categories involved in the food industry, and the detection methods and delivery methods are different according to different food. High Dream considers customer needs and provides a variety of gravity feed metal detectors such as conveyor belt type, stand-up packet type, inclined type, modular type, etc. So that metal foreign impurities in food packaging have nowhere to hide.


High Dream intelligent gravity metal detector is a kind of sophisticated inspection equipment, mainly used to detect metal in product packaging and eliminate metal impurities. It can be widely used in food, medicine, chemical, textile and other industries to improve food safety and quality.


Gravity fall metal detector is generally installed with gravity flow tube, the bottom of the multi-head weigher and the feed port of vertical bag packaging machine, for detecting powder, granular, and snack food before being packed, widely used in metalized bag packing lines.   


Food packaging needs to go through multiple and continuous steps, including weighing, packaging and testing. High Dream has rich experience in the entire food weighing and packaging process, and can coordinate and combine gravity feed metal detectors with other equipment during installation and debugging to ensure the quality and safety of food packaging.


High Dream gravity metal detector, will always be the "gatekeeper" to protect food safety.

Help consumers stay away from the risk of metal impurities and enjoy safe and worry-free food!

It features intelligent fault alarms, so equipment failures can be easily detected, making maintenance easier. It is also equipped with a high-speed staggered discharge function to prevent material blockage.
It is also equipped with automatic feeding and is known for its high precision and high standards. All of its components are based on international standards, enhancing the interchangeability of the whole machine parts.
The integrated welding of the chassis and the middle seat greatly increases the strength of the machine. Its operator interface can be set to many languages, which makes it highly competitive in the global market.It supports multi-stage weight calibration and is compatible with many products made of different materials.
 Its precise construction greatly enhances the feeding rate and allows the material to flow smoothly. Highdream's perfect mold manufacturing technology makes sure that the weigher can be used to better prevent materials from falling and can effectively control the materials adhesion problem to ensure weighing accuracy.

What are the operating procedures of the gravity fall metal detector?


In order to ensure the quality and safety of products, many industries currently need to use metal a gravity feed metal detector to test products, and the accuracy of detection has a lot to do with equipment and operations. What are the operating procedures of the gravity fall metal detector?


Gravity feed metal detector operating procedures

 Boot preparation:

Before starting the gravity fall metal detector, check whether the conveyor belt is clean, and whether there are obstacles or pollutants, otherwise these substances will affect the detection accuracy of the equipment, and then turn on the power and let the equipment warm up for 30 minutes!


Sensitivity setting:

The detection requirements of products in different industries are different, and the effects of different products are different. These factors will affect the subsequent detection accuracy, so the sensitivity of the gravity feed metal detector should be set before use, and a standard metal test block should be used. (Fe: Φ is less than 0.8mm, SUS: Φ is less than 1.8mm) for inspection, if it fails, it is normal!


Sensitivity Calibration

Standard metal block detection test:

Put the two test blocks in an empty box with a small product effect, and then place them in the left, middle, and right places of the belt in turn, the detector should be able to alarm and stop running (3 times for each test block);


Simulated metal detection:

Put the two test blocks on the upper and lower parts of the product respectively, and pass through the left, middle, and right positions of the detector conveyor belt respectively. The gravity fall metal detector should be able to alarm and stop running (6 times for each test block). If the gravity fall metal detector can alarm and stop running every time it is tested, it means that the sensitivity of the equipment is qualified and product testing can be carried out!


Product testing

After all the procedures in the current period are completed, the product can be put into the product for testing. If it can pass smoothly and there is no alarm, the product is a qualified product;

If the gravity feed metal detector beeps and stops running, it is suspected that there is metal foreign matter mixed in the product. For unqualified products, repeat the inspection 3 times. If there is no alarm for 3 times, it can pass, but there is any 1 alarm. If it is suspected that there is metal foreign matter mixed in the product, it needs to be processed in the next step!
