METTLER TOLEDO Safeline pipeline metal detectors are designed for inspecting pumped liquids, pastes, slurries, high viscosity fluids and vacuum-packed products in industrial food and non-food processing applications. Our Pipeline metal detectors are capable of detecting all types of metal and ensuring they are removed from the process flow.
Safeline metal detectors use sophisticated technology to provide advanced metal detection solutions, capable of detecting all metal types including ferrous, non-ferrous (including aluminium and brass), and difficult to detect stainless steel, and eliminating contaminated product from the process flow. Our Profile Advantage Pipeline metal detector uses Multi Simultaneous Frequency and Product Signal Suppression technology to detect smaller metal contaminants in the most challenging applications.
Heavy duty, stainless steel pneumatic reject valves with quick release couplings automatically remove metal contaminated product from the process flow. The use of Safeline's ZMFZ (Zero Metal Free Zone) technology allows the metal fittings of the throughput pipe and other process equipment to be positioned closer to the detection head without affecting the detector performance. This facilitates a short throughput pipe for maximised product quality in restricted installation spaces.
METTLER TOLEDO Safeline's Pipeline metal detectors are designed to inspect all most types of liquids, pastes and slurries for metal contamination, even in the most challenging food processing environments. The operator control panel can be installed remotely from the search head, enabling the point of inspection to be located in inaccessible places such as in elevated pipes and in complex and congested pipeline networks.
Inspection of pumped liquids, slurries and pastes can be achieved by replacing a short section of metal in the transport pipe with a food-grade non-metallic pipe that passes through a metal detector. The choice of the pipe will be influenced by:
Care should be taken to design the installation so that the pipe will not be under strain from the weight of the incoming and out-going stainless steel transport pipes.
Our HDS Pipeline metal detectors are designed for easy integration with other process equipment. Sealed to IP69K standard, the rugged heavy-duty wash-down construction is designed to withstand the rigours of the harsh environments found in meat and food processing plants. The space-saving design can be configured through a range of accessories to suit production of continuous, linked or clipped sausages and other food products in natural or collagen cases. Internal Cancellation Field technology allows the metal fittings of the throughput pipe and other process equipment to be positioned closer to the detection head without affecting the detector performance. This enables a short throughput pipe, essential to avoid product creaming* and gives the added benefit of a compact system size to reduce space requirements.
Product Creaming (sometimes referred to as smearing) occurs when the increased length of product flow gives rise to the fats in some food products being unevenly distributed towards the outside of the sausage or tube pack due to friction build up on the inside of the throughput pipe.
METTLER TOLEDO Safeline's unique Profile Advantage Pipeline metal detector is ideal for use in challenging applications with product effect, for example, where product is not standardised, or when there is a potential for bubbles or voids to be present in the product flow. Using a combination of Multi-Simultaneous Frequency and Product Signal Suppression technology, Profile Advantage Pipeline metal detectors can overcome the issue of product effect to virtually eliminate false rejects, maximizing operational efficiency and improving productivity.
When metal contamination is detected, a sanitary three-way valve can operate to divert the contamination. Alternatively, the pump can be stopped and the contamination flushed out manually. The choice of the valve will be influenced by product type, temperature and viscosity. Some valves are best suited to low-viscosity products such as juices. If the pipe-cleaning procedure includes a cleaning plug being flushed down the pipe, the selected valve must be of a ‘straight-through’ non-restrictive design.
