Nahr-Engel Utilises Mettler Toledo Checkweigher

Mettler Toledo has revealed that Nahr-Engel, a manufacturer of dehydrated potato products, is using product inspection technologies, including checkweighers, as part of its quality control processes. Nahr-Engel uses an S-series checkweigher to verify the weight of all products in its various lines of dehydrated potatoes. The company's newest equipment purchase is a Garvens XE3 checkweigher with a strain-gauge weighing cell, which checks whether the packing machine has inserted all three mashed potato sachets into cartons on the mashed potato flakes line.

The XE3 checkweigher is the last quality control station at Nahr-Engel and automatically rejects all cartons with missing potato sachets. This completeness checking is done at a conveyor speed of up to 45m per minute, checking up to 100 cartons per minute. The compact checkweigher can rapidly verify the weight of cartons between 100-2,000g at an accuracy level adequate for checking completeness, in addition to being cost-effective. It also features a fully adjustable height setting, a sorting/rejection device tailored to product characteristics, and continuously variable conveyor speed control to match the line speed.

In addition to the weighing technology, Mettler Toledo also offers solutions to check food products for foreign bodies. During production at Nahr-Engel, Mettler Toledo Safeline metal detectors verify that the dehydrated potato products are metal free. As part of Mettler Toledo's Profile platform of products, this metal detector was designed for simple integration into food production lines and provides reliable metal detection during production.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
