Manta Offers High Resolution Scanning to Detect and Remove the Smallest Defects and Foreign Material
:: 31 March, 2008
Key Technology introduces Manta(TM), a new state-of-the-art high volume, high performance sorter featuring a two-meter wide scan area that dramatically increases throughput within a space-saving footprint.
Handling up to 27 metric tons (60,000 pounds) of processed vegetables or fruit per hour, Manta offers high resolution scanning to detect and remove the smallest defects and foreign material. In addition to processed vegetables and fruit, Manta is being developed for other industry applications.
Designed for exceptional versatility and superior sanitation, this innovative sorter increases production capacity while maximizing product quality and food safety.
With the highest number of sensors and image processing modules of any sorter on the market, Manta maintains the high resolution of the finest narrow-belt sorters on its wider, higher capacity frame. Designed for flexibility, Key can configure Manta with up to eight top-mounted color or Vis/IR (visible infrared) cameras and up to two top-mounted FluoRaptor(TM) fluorescence-sensing lasers. Optional bottom-mounted sensors can be added to meet the specific needs of each application. Extreme modularity allows Manta to be easily reconfigured in the field, which enables processors to confidently select a camera/laser arrangement today knowing that the sorting system can grow if their needs change.
Manta's dynamic design supports on-belt viewing as well as off-belt, in-air viewing, which can also be modified in the field at a later date if needed.
Using Key's proprietary color cameras, Manta recognizes each object's size and shape as well as millions of subtle color differences to remove defects based on user-defined accept/reject standards. Adding FluoRaptor to Manta expands the sorter's inspection capabilities by reliably detecting foreign material (FM) and extraneous vegetable matter (EVM) based on differing levels of chlorophyll. Combining color and laser sorting on one platform provides the most comprehensive sort available today.
Manta features a 2-meter (79-inch) wide scan area and handles up to 27 metric tons (60,000 pounds) of product per hour in a footprint that is similar to Tegra. Compared to Optyx 6000, which easily handles 10 metric tons (22,000 pounds) of product per hour, and Tegra®, which typically handles up to 14 metric tons (30,000+ pounds) of product per hour, Manta dramatically increases throughput while maintaining optimal performance.
"Bonduelle, one of the largest vegetable processors in Europe, has purchased a Manta to be installed in early 2008. Their Manta sorter will be configured to handle a range of vegetables including peas, multiple varieties of beans, multiple forms of carrots, and also potatoes, turnips, and more," noted Bret Larreau, Processed Vegetable and Fruit Industry Marketing Manager at Key Technology. "Every customer that has seen Manta in operation in our test facility has been impressed with its performance, simplicity and ease of use. We are excited that in addition to Bonduelle, we have multiple Manta sorters being installed in various plants around the world for the upcoming 2008 processing season."
Simplicity is a guiding principle in the design of Manta. To ease installation, Key designed Manta to be self-contained and complete. Unlike other sorters that require additional elements such as separate cooling systems, water filters, and air dryers, Manta incorporates all the necessary components in one system. Simply connect air, water, power and start sorting.
State-of-the-art sanitary design concepts are incorporated in the design and construction of Manta. Fewer horizontal surfaces where debris can build up and no overlapping surfaces that can trap bacteria make Manta less susceptible to sanitation problems. With stainless steel construction, water-tight double-gaskets on doors, a sealed control panel, and easy access to areas needing cleaning, Manta is designed to operate reliably in the harshest environments and easily withstand high pressure washdowns.
Ease of use, despite the sophistication of the underlying technology, sets Manta apart from other sorters on the market. The icon-based graphical user interface (GUI) is easy to learn and use, reducing operator training and simplifying optimum operation. Product settings can be stored and retrieved for fast product changeover. The GUI can reside locally and can be accessed remotely via its OPC-compliant infrastructure, enhancing the flexibility in the operating environment and easing access for remote factory troubleshooting and application assistance. Sophisticated real-time and on-demand diagnostics help avoid costly downtime and detect conditions that could compromise inspection.
To ease maintenance, Manta features an open design and fewer, larger cabinet doors that provide greater access to the sorter's electronics and hardware.
Quick release components allow Manta's belt to be changed quickly and easily.
Based on Key's powerful G6 electro-optical platform, Manta offers the most advanced image processing in the industry. Featuring a modular design and proven, high performance connectivity standards such as Camera Link(TM), FireWire® and Ethernet, Manta ensures forward compatibility to maximize a food processor's long-term return on investment.
Note for FireWire
FireWire is Apple Inc.'s brand name for the IEEE 1394 interface. It is also known as i.LINK (Sony's name) and DV (Panasonic's name, not to be confused with DV camcorder tapes). It is a serial bus interface standard, for high-speed communications and isochronous real-time data transfer, frequently used in a personal computer (and digital audio and digital video).
FireWire has replaced Parallel SCSI in many applications, due to lower implementation costs and a simplified, more adaptable cabling system. IEEE 1394 has been adopted as the High Definition Audio-Video Network Alliance (HANA) standard connection interface for A/V (audio/visual) component communication and control. FireWire is also available in wireless, fiber optic, and coaxial versions using the isochronous protocols.
Almost all modern digital camcorders have included this connection since 1995. Since 2003 many computers intended for home or professional audio/video use have built-in FireWire/i.LINK ports, including all Sony computers, all but one of Apple's computers (and many of its older iPods), and most Dell and HP models currently produced. It is also available on many retail motherboards for do-it-yourself PCs.
The system is commonly used for connection of data storage devices and DV (digital video) cameras, but is also popular in industrial systems for machine vision and professional audio systems. It is preferred over the more common USB for its greater effective speed and power distribution capabilities, and because it does not need a computer host. Perhaps more importantly, FireWire makes full use of all SCSI capabilities and, compared to USB 2.0 Hi-Speed, has higher sustained data transfer rates, especially on Apple Mac OS X (with more varied results on Windows, presumably since USB2 is Intel's answer to FireWire on Windows machines), a feature especially important for audio and video editors.
FireWire can connect up to 63 peripherals in a tree topology (as opposed to Parallel SCSI's Electrical bus topology). It allows peer-to-peer device communication — such as communication between a scanner and a printer — to take place without using system memory or the CPU. FireWire also supports multiple hosts per bus. It is designed to support Plug-and-play and hot swapping. Its six-wire cable is more flexible than most Parallel SCSI cables and can supply up to 45 watts of power per port at up to 30 volts, allowing moderate-consumption devices to operate without a separate power supply. (As noted earlier, the Sony-branded i.LINK usually omits the power wiring of the cables and uses a 4-pin connector. Devices have to get their power by other means.)
FireWire devices implement the ISO/IEC 13213 "configuration ROM" model for device configuration and identification, to provide plug-and-play capability. All FireWire devices are identified by an IEEE EUI-64 unique identifier (an extension of the 48-bit Ethernet MAC address format) in addition to well-known codes indicating the type of device and the protocols it supports.
Note for Ethernet
Ethernet is a family of frame-based computer networking technologies for local area networks (LANs). The name comes from the physical concept of the ether. It defines a number of wiring and signaling standards for the physical layer, through means of network access at the Media Access Control (MAC)/Data Link Layer, and a common addressing format.
Ethernet is standardized as IEEE 802.3. The combination of the twisted pair versions of Ethernet for connecting end systems to the network, along with the fiber optic versions for site backbones, is the most widespread wired LAN technology. It has been in use from around 1980 to the present, largely replacing competing LAN standards such as token ring, FDDI, and ARCNET. In recent years, Wi-Fi, the wireless LAN standardized by IEEE 802.11, is prevalent in home and small office networks and augmenting Ethernet in larger installations.
Ethernet was originally developed at Xerox PARC in 1973–1975. Robert Metcalfe and David Boggs wrote and presented their "Draft Ethernet Overview" before March 1974. In March 1974, R.Z. Bachrach wrote a memo to Metcalfe and Boggs and their management, stating that "technically or conceptually there is nothing new in your proposal" and that "analysis would show that your system would be a failure." This analysis was flawed in that it ignored the "channel capture effect", though this was not understood until 1994. In 1975, Xerox filed a patent application listing Metcalfe and Boggs, plus Chuck Thacker and Butler Lampson, as inventors (U.S. Patent 4,063,220 : Multipoint data communication system with collision detection). In 1976, after the system was deployed at PARC, Metcalfe and Boggs published a seminal paper.
The experimental Ethernet described in that paper ran at 3 Mbit/s, and had 8-bit destination and source address fields, so Ethernet addresses were not the global addresses they are today. By software convention, the 16 bits after the destination and source address fields were a packet type field, but, as the paper says, "different protocols use disjoint sets of packet types", so those were packet types within a given protocol, rather than the packet type in current Ethernet which specifies the protocol being used.
Metcalfe left Xerox in 1979 to promote the use of personal computers and local area networks (LANs), forming 3Com. He convinced DEC, Intel, and Xerox to work together to promote Ethernet as a standard, the so-called "DIX" standard, for "Digital/Intel/Xerox"; it standardized the 10 megabits/second Ethernet, with 48-bit destination and source addresses and a global 16-bit type field. The standard was first published on September 30, 1980. It competed with two largely proprietary systems, token ring and ARCNET, but those soon found themselves buried under a tidal wave of Ethernet products. In the process, 3Com became a major company.
Ethernet was originally based on the idea of computers communicating over a shared coaxial cable acting as a broadcast transmission medium. The methods used show some similarities to radio systems, although there are fundamental differences, such as the fact that it is much easier to detect collisions in a cable broadcast system than a radio broadcast. The common cable providing the communication channel was likened to the ether and it was from this reference that the name "Ethernet" was derived.
From this early and comparatively simple concept, Ethernet evolved into the complex networking technology that today underlies most LANs. The coaxial cable was replaced with point-to-point links connected by Ethernet hubs and/or switches to reduce installation costs, increase reliability, and enable point-to-point management and troubleshooting. StarLAN was the first step in the evolution of Ethernet from a coaxial cable bus to a hub-managed, twisted-pair network. The advent of twisted-pair wiring dramatically lowered installation costs relative to competing technologies, including the older Ethernet technologies.
