Nectar Group adapts its equipment to local conditions
Nectar Group has provided an expert and bespoke service to the dry bulk handling market since its inception in 1972. The success of services provided by the group has been recognized with international awards and accolades through the years. Striving to be the best in the market has meant that the company is always looking at ways in which it can further add value to the already beneficial level of service provided to clients around the world.
As a result Nectar has developed a level of unrivalled flexibility and knowledge in operations covering 74 countries globally. The demand for bulk handling and bagging services of the group has changed significantly over the last decade. Whilst the company’s core business, providing mobile bagging facilities, was once solely operating within a select few countries in Africa, Nectar’s bagging units can now be seen in nearly every continent around the world. With a constantly changing bulk import and export market throughout the world, new locations generally bring with them new handling challenges and often new logistical difficulties to be resolved. Rather than trying to fit a round peg in a square hole Nectar Group has successfully made alterations to its existing range of equipment in order to meet the specific demand in newly developing geographical areas. For example South America generally differs from other continents in that bagging systems often incorporate valve bagging rather than filling standard open mouth bags. To conform to this, Nectar went back to the drawing board and designed a completely mobile bagging machine contained within a 10ft container that utilizes a screw feed conveyor to automatically fill valve bags with just two operators. This is a variation of Nectar’s 10ft Impac bagging machine. The single line ultra-mobile bagging unit, which comprises of the same advanced double weighing technology and electrical control systems as Nectar’s award winning Compac M140, was developed for operation with restricted space as it occupies a minimal footprint area but maintains a bagging speed of 60 tonnes per hour.
Various other locations have called for different design briefs including multiple line fixed bagging systems capable of up to 6,000 mts pwwd feeding straight from a silo or bagging bulk cargo in a port straight from containers into one-tonne bags. Ultimately, however, the principle remains the same whatever the method — fast, simple, bagging solutions anywhere, anytime. In its endeavours to fulfil its brief the company encounters many challenges. Despite features, such as the most advanced double weighing bunkers and electronic weighing control systems on the market, Nectar frequently encounters problems in relation to the other aspects of the handling process which in turn affect the overall cargo handling chain.
It is said that a chain can only ever be as strong as the weakest link which is very true with the cargo handling process. As such, deficiencies along the chains can often disappoint parties involved in the chain including final users of a commodity. Even today, labour-intensive manual bagging is in operation in many locations with unsatisfactory consequences for the end users or the receivers. This type of operation often leads to various issues such as unreliable bag weights, slow speed due to lack of labour and damaged or stained bags as a result of multiple handling processes. Nectar’s mechanization of this process has had a knock-on effect with pressure being put on trucking companies and storage providers to step up to the
plate and increase their performance. Not only is it a case of speed of handling and transport but it is also one of quality of product and reduction of loss. Although Nectar’s bagging systems operating in discharge ports have been proven to significantly reduce damage and loss from multiple handling and traditional manual bagging, there are still issues which need to be seriously considered in order to modernize the overall handling chain. Nectar often experiences cases where the onward handling of the product, following from where Nectar’s responsibility ends, proves to be detrimental to the overall quality of the accumulative services in the handling chain. Whether it be the tearing of bags by poor handling or the sub-standard storage before delivery, there needs to be a joint effort in the industry in smoothing out the process to ensure the end user receives the best possible quality product on time. After all, a healthy and efficient supply chain will promote a healthy demand for these products and thus, overall, lead to a healthy and profitable market.
Although the trend towards containerization continues in developing ports, the standardization of bulk handling operations lessens the risk to those knowledgeable enough to ship in bulk and bag at destination utilizing the advanced technology now on offer from Nectar. Besides, the financial rewards are becoming more and more prevalent.
Despite the different practices seen in various parts of the world, the company is involved in many Greenfield and general facility improvement projects displaying a general shift towards more standardized procedures being implemented in the developing world. In the last few years Nectar has developed a new role in the market from purely providing mobile bagging services to growing its consultancy and development arm to
incorporate this shift in the general perception and therefore control a larger portion of the chain. This demand, whether in relation to a coal terminal, stevedoring procedure or safety standards surrounding port activities has largely been driven by the desire not to be left behind in the ever developing international market. As a company with 40 years of experience in extraordinary cargo handling projects around the world, Nectar is well placed to advise and implement streamlined solutions in line with its motto — ‘Driven by innovation, performance guaranteed’.
SMB flexible filling system: big bags filled safely
The demands on filling systems are increasing all the time — the time factor plays an ever greater role and, depending on the product, statutory conditions also have to be considered. High performance and operating safety in constant operation, as well as special technologies for faster, risk-free bag filling: these are properties that go side by side with systems from SMB International GmbH. As one of the front-runners in the bag filling sector, the company produces co-ordinated filling systems, barrel filling systems, canister filling systems and keg filling units. Through flexibility in design and close co-operation with the individual customer, SMB contrives to design and produce a very diverse range of solutions meeting all requirements. “We distinguish between standard, semi-automatic and fully automatic filling machines,” explains Jens Hachmann, a chartered engineer and technical director with the SMB Group. “With the latest systems, a single employee simply selects the stored product record on the control panel and controls the machine — everything else runs automatically.”
DESIGN OF A BIG-BAG FILLING SYSTEMProduction system optimization plays an important role in filling processes. With a multi-functional and flexible bag filling system, SMB, based in Quickborn, Germany, has achieved a fast and, at the same time, highly accurate method for weighing and packing goods in big-bags.
With the design of a big-bag filling system for food granules, SMB has fulfilled the wishes of one of its customers, an international trading company in the food processing and bag
filling sector, with considerable rationality and functionality. The big-bag filling device consists of a fixed ground gantry. To this are secured hoppers, an MBA200 overflow protection unit from SMB’s sister company, MBA Instruments GmbH, a dust filtration system and a dosage valve unit. A vertical drive unit is incorporated on the inner gantry, with which big bags of varying heights are filled. A connected scales system checks the filling to an accuracy of one gramme. Sacks are then stacked on a pallet. Pallets are taken individually from an empty pallet rack upstream — an automatic sheet applicator prepares pallets to accommodate the big-bag.
For good accessibility in the hanging process, the hooking loops, which are fitted with a pneumatically controlled release, are moved to the user. In the same user-friendly movement, the filler head is forced with a stretch sleeve, which is responsible for the air-tight closure of the sack opening. “We have developed a variety of filling systems with the market of the future in mind, which we have tailored specifically to the needs of our customers and integrated into their existing production lines as necessary,” declares Andreas Heckel, one of the SMB Group’s directors, in conclusion.
THE SMB GROUPThe SMB Group unifies the areas of filling and materials handling, vessel loading, warehouse technology, filling level measurement technology and conductivity measurement under the brands SMB and MBA. The SMB Group sees itself as a complete system solution provider with its business focus on planning, development, production and the worldwide distribution and service of highly complex systems, as well as warehouse logistics. Long ago, SMB took the deliberate decision that a high percentage of its products would be manufactured in-house at its production site in Quickborn. The main reason is to respond quickly to customer wishes and to achieve consistently high quality. The decision for a high amount of production depth and consequently, increased reliability with regard to quality and on-time deliveries is achieved by SMB through its own design and production of mechanical and electrical assemblies. The installation and service teams support both large national and international projects. A comprehensive, worldwide operating sales network provides for quick implementation.
FIBC spout from JEM International/Express Scale Parts: fast and flexible
US company JEM International/Express Scale Parts has been manufacturing equipment for the bag filling industry for 35 years. Until recently, the company has been a very minor player in the FIBC (flexible intermediate bulk container) part of this industry, but it is now more aggressively interested in this market.
The design that JEM International/Express Scale Parts is utilizing is significantly different than all other US manufacturers. It has basically designed a FIBC spout assembly that consists of three separate rings, as illustrated.
The inner ring 8” diameter is where the product will flow through. The product is controlled by a gate above the entrance to this ring. The second ring is typically 12” in diameter. The distance between these two rings is where the negative air will be drawn from the system during the filling cycle. The outer ring is 18” in diameter and contains a bladder that inflates from outward in against the 12” inner ring.
The system is extremely easy to operate. The operator will place the fill spout of the FIBC against the 12” diameter ring.
Once in place, a push button is activated which will inflate the bladder from the 18” diameter ring inward, creating a 100% dust tight seal during the filling cycle. A timer then will activate a blower which will inflate the FIBC and when the blow cycle is completed the filling will begin through the 8” inner ring and the displaced air will then be extracted between the 8” and 12” rings through a separate valve.
The advantage of this system is that by inflating from outward inward, the user is not limited to exactly one size of fill spout in the FIBC and the inflation eliminates the need for hanging the four corners of the bag on a separate rack
assembly. It is far quicker for the inflation system to work than for an operator to manually hang the four corners and release the four corners.
This spout assembly can be supplied with a net weigh scale or a platform gross weigh type scale.
