Trantec’s Nano screw feeders: micro-dosing and ultra-low feed rates
Trantec’s Nano screw feeder range takes proven feeding technology and applies it to the miniature world of ultra-low dosing of powders, flakes, and granules.
For over two decades Trantec Solids Handling has specialised in the design and manufacture of powder metering equipment. This expertise has now been applied to the unique complexities of feeding powders at very low rates.
Steady flow at grams per hour
A selected few companies offer feeding rates lower than fifty grams per hour. However, some micro-dosing applications target quantities well below this. Therefore, equipment becomes challenging to find, if not unobtainable. Trantec’s Micro and Nano feeder range takes proven feeding technology and applies it to the miniature world of ultra-low dosing of powders, flakes, and granules. Providing a steady flow at exceptionally low rotational speeds, dosing as little as a few milligrams to several grams per hour, with extremely high accuracies. To enhance the micro feeder’s accuracy and controllability, optional gravimetric type weigh and control systems are available, suitable for both gain in weight and loss in weight applications.
Robust and resistant
Trantec’s micro feeders are robust in design, manufactured from 316 stainless steel, precision machined from solid billets, making the feeder very robust and capable of operating in harsh environments as well as laboratory benches.
CNC for tight tolerances
Refilling the micro feeder is simple and can be carried out manually or with a second volumetric feeder under the control of the Micro feeder. The machine is low maintenance, consisting of only two specially selected moving parts, the independently driven rotating agitator and stainless-steel auger. The agitator and auger have variable speed functions that can provide either an intermittent or constant run, depending on the application requirements. Trantec manufactures auger screws as small as 4mm in diameter, including multi-start flights, designed to effectively extend the dynamic range for maximum accuracy. Small multi-flight augers are near impossible to fabricate using traditional techniques. Trantec have developed software and work holding techniques in conjunction with their advanced in-house CNC (Computer Numerical Control) machines. CNC machines allow Trantec to consistently produce precise parts that meet the tight tolerances essential with micro dosing machinery.
Crack and crevice free design
Optional features are available to enhance the feeders for pharmaceutical and food applications and meet the highest specifications in the bulk solids industry. Crack and crevice free design is included with these metering feeders. PTFE dry running shaft seals that can withstand aggressive environments are standard. Meeting the needs of applications where there are harsh chemicals, high pressure, extreme temperatures. For sanitary material handling Trantec feeders use Metal detectable blue silicone seals and can include an overall mirror polish (0.2Ra) finish.
Easy-clean features
Quick-release, easy-clean features are included as standard with all contact parts autoclave and dishwasher compatible, which enables rapid dismantling of the machine in under one minute without the use of tools.
