The company TPLG was founded in 1959 when French agriculture, after the US, was undergoing far-reaching technological changes. Indeed, the modernization of agriculture produced a deep impact especially on the way in which the harvest was processed. With the advent of the combine harvester, crops now came as bulk material; this meant that farmers had to provide themselves with appropriate storage equipment. From the start, TPLG decide to design machinery for the handling, cleaning, storage and ventilation of cereals so as to allow the preservation of the crops under the best possible conditions, both at the farm and at the cooperative storage sites.
The changes in French agriculture deepen throughout the 1960s; and farm mechanization entails a complete reorganization of the land. France enters the era of intensive and industrial agriculture. Increasingly large areas of open farm land provide the opportunity to produce new crops such as corn. In this context, TPLG, while pursuing the business of storage installations, design, manufacture, and install grain dryers. This first diversification will last for more than a decade until, in 1982, corn farming in the northern part of France will drop by over 80 %.
1977 is an important year for TPLG. Our engineering team invent the very first automatic grain sampler. Bearing in mind that sampling is an essential operation, all too often neglected but also rivalled by various manual methods still in use today, TPLG designs the automatic truck probe called Jumbo. Controlled from inside the laboratory room of the storage centre Jumbo allows the intake of a 2 dm³ sample through a grain load height of 1.50 m at any given point in the vehicle. The grain is taken in by gravity flow through the openings in the probe spear sidewall, and the transfer of the sample to the laboratory is accomplished by a pneumatic system.
After a slow start, the Jumbo truck probe soon proves to be the only French-made automatic grain sampling machine. 1982 is another turning point in the history of TPLG. As the grain dryer production had to be discontinued, the company management decides to reinforce their engineering team and to create a section that specializes in silo renovation and the upgrade of grain storage and handling facilities to comply with the newly imposed standards. The persistent increase of sown land surfaces, higher yields, and the multiplication of new varieties require an almost total upgrade of the handling equipment among the vast majority of grain storage organizations.
Indeed, their productivity and their storage capacity have to be increased. TPLG take an active part in this process of modernization and prove able to provide tailor-made projects for each site to improve its storage and handling capacities, and to implement the upgrades thanks to work of its dedicated teams of fitters.
At the same time, TPLG becomes a major player in the field of high capacity barge loading systems. Its engineering department plans and designs specific loading equipment for river and sea port facilities.
1985 is undoubtedly a year everybody at TPLG will remember. On March 1st, 1985, our factory produces the first of an altogether new generation of grain samplers: HERON. Unlike its predecessor Jumbo, which was driven by hydraulic power, HERON is electromechanically powered with a fully automatic dumper bottom detection, and what is more, the sampling action no longer calls upon gravity flow, it is now accomplished by vacuum intake throughout the entire height of the grain load in the incoming and outgoing trucks and trailers. With TPLG, grain sampling becomes an extremely easy and simple operation. The machine is an instant sales hit!
In the early 1990s several serious accidents occur in silos due to poor airborne dust removal. The major cooperatives and trading companies turn to TPLG asking them to devise and install new grain ventilation systems which comply with the latest European safety standards.
There again, TPLG takes on the new challenge. Upgrading operations start in 1998. Very soon TPLG evolves to be one of France's leading specialists for tall silo renovation (50 metres high).
At the same time, the HERON samplers add a new member to their family, a device which is able to sample grain directly from the grain carrying circuit ductwork. They are compact in size, but offer exceptionally high performances: Scorpion, Mini-Scorpion, and Moustick samplers allow samples to be taken at any stage of the grain handling process.
In 2001, HERON III (3rd generation) totals 1500 units. Significant technological progress has been made since the first sampler HERON had entered service in 1985. This third generation of grain samplers features matchless high-end technology that is unequalled in Europe.
Fully automated, made from the best materials available at that time, the HERON III grain sampler combines tough and aesthetic design, reliability, and representative sample intake.
TPLG's clients are our best ambassadors. In 2002, covering a share of more than 85 % of the domestic market, TPLG decide to start selling the HERON III to their European neighbours.
By December 31, 2007, more than 250 HERON III have been installed in about 20 European and North-African countries. On the home market in France, about 2300 machines keep doing their job every day.
2007 is a new turning point for TPLG's activity for two reasons.
In April, the TPLG factory turns out the latest development of the HERON type grain samplers, HERON 3000. This machine takes its technology to yet another level; not only does it offer the choice between straight vacuum intake and a core sampling probe, it also has all of its drives controlled through inverters (VFDs) which, among other things, allow an adjustment of the force of penetration into the grain depending on the type of cereals being sampled, and speed modulation of the swivel drives, as well as electronic detection of the trailer bottom thus facilitating the automatic reversal of the drive and upward movement of the probe.
2009 also marks the ever increasing desire of the main actors in the agricultural and food-processing industry to automate, either fully or partially, the process of raw materials sampling and analysis. Here, too, TPLG have been able to come up with ingenious solutions showing their capacity to respond quickly to, and accompany the evolution of the trade.
And, 2009 also marks the return of farm storage. In many years TPLG have not experienced such a wave of enquiries from farmers to plan and design new storage installations. Relying on the most powerful software of the moment, TPLG provide custom-made three dimensional project studies to their clients.
On October 1st TPLG and JAMASE decide a merger to join their competence and know-how in the field of farm storage.
Meanwhile, the sampling equipment division keeps growing and developing.
2010 sees the birth of the CAMELEON sampler, a machine specifically designed for sampling operations from railcars and tankers.
2012 marks the beginning of the sales of the PREMIUM range, i.e. purpose-built machines for commercial facilities (with over 300 trucks per day to be sampled).
2013 TPLG grain samplers are now present in 51 countries.
2015 Another step forward is made launching the new Series 4000 machines into the market.
