What are the two types of metal detectors used in food industry?

Types of Metal Detectors Used in the Food Industry

In the food industry, metal contamination is a serious concern, and effective metal detection systems are crucial for ensuring product safety. There are two main types of metal detectors commonly used in the food industry: gravity-fed metal detectors and conveyorized metal detectors. Each type is suited for different stages of food processing, based on the specific requirements of the food product, processing speed, and contamination risk.

1. Gravity-Fed Metal Detectors

Gravity-fed metal detectors are typically used for inspecting bulk products or powders that fall under their own weight. These detectors are commonly used in applications where the product is poured or falls through the detector’s aperture, allowing it to be screened for contaminants. The detector typically detects ferrous, non-ferrous, and stainless steel metals.

Applications:

· Bulk powders and granules

· Pet food

· Spices

· Cereals

· Processed foods like flour or sugar

Gravity-fed metal detectors are often found in industries that deal with bulk materials or products that do not need to be conveyed on a belt. Since these detectors rely on gravity to move products through the detector, they are best suited for products that do not require high-speed inspection.

Techik’s Gravity-Fed Metal Detection Solutions:

Techik offers highly efficient gravity-fed metal detectors that integrate advanced technologies to detect a wide range of metal contaminants. Techik’s gravity-fed models provide high accuracy in detecting contaminants such as ferrous, non-ferrous, and stainless steel, even in bulk products.

These systems are particularly designed to meet industry standards for food safety and hygiene, and they come equipped with features that allow for easy integration into existing production lines. They offer high sensitivity and can detect small metal particles, ensuring compliance with regulatory requirements and maintaining product quality.

2. Conveyorized Metal Detectors

Conveyorized metal detectors are the most common type of metal detection systems in the food industry. These detectors are designed for inspecting food products moving along a conveyor belt, making them suitable for a wide range of packaged and processed foods. The product moves through the detection system while being monitored by highly sensitive electromagnetic coils. When metal contaminants are detected, the system automatically rejects the contaminated product via a rejection mechanism.

Applications:

· Packaged foods (snacks, frozen foods, ready meals, etc.)

· Meat and poultry products

· Confectionery

· Beverages

· Bakery products

Conveyorized metal detectors are often more versatile than gravity-fed systems, as they can handle both bulk and packaged food products at varying speeds. They are highly efficient in high-speed production lines, ensuring that products are inspected for metal contaminants without slowing down the process.

Techik’s Conveyorized Metal Detection Solutions:

Techik's conveyorized metal detectors offer excellent sensitivity and speed, designed for use in high-throughput production environments. Their metal detection systems are equipped with multi-spectrum detection to identify contaminants across a wide range of metal types, including ferrous, non-ferrous, and stainless steel.

Techik's conveyorized models ensure high accuracy in detecting even the smallest metal fragments. These detectors are ideal for ensuring that packaged food, such as meat, snacks, or beverages, is free of harmful metal contaminants.

Techik’s MD-Pro series metal detectors, for example, are designed for integration into conveyor systems, offering high detection performance in fast-paced environments. These systems are equipped with advanced features such as automatic calibration and user-friendly interfaces, making it easy for operators to adjust settings and ensure the system is always running at peak efficiency. Additionally, Techik’s detectors can be integrated with sorting and rejection systems that automatically remove contaminated products, ensuring that only safe food reaches the consumer.
