Flame-Weeding Technology
hopfenFLAMM 2450
Set new, environmentally friendly and trend-setting standards for weed removal in hop cultivation. The preservation of nature is our task. You too can contribute. For an environmentally friendly interaction between humans and nature, we all have to break new ground.
Since 2007, Reinert has been accompanying the first trials in hop cultivation with the equipment technology, which has been tried and tested in organic farming for over 50 years. In cooperation with several hop growers, Reinert has developed and continuously improved an appropriate cultivation flame nozzle for hop cultivation on the basis of this experience.
Today, the innovative result of our development is the special device hopfenFLAMM 2450.
For some years now, the use of chemical pesticides has become more and more
complicated and increasingly restricted by the legislator. The flame technique offers
an interesting opportunity to eliminate weeds, fungi and spores in an environmentally friendly and effective way.
With the special hopfenFLAMM 2450 device, you can completely dispense with the use of chemical pesticides in hop cultivation. The flame-weeding technology is easy to use for bifang care and defoliation.
Description
The hopfenFLAMM 2450 add-on flame-burning device is attached to the front
hydraulics on the tractor for optimal visibility. It can be extended and retracted
hydraulically by approx. 40 cm on both sides.
The total displacement range is therefore approx. 80 cm. This means that all
common row widths can be covered and the device can be reduced to a minimum
transport width. This requires a double-acting control unit on the tractor.
The gas tank is carried on the tractor using a three-point rear attachment. The scope
of delivery of the flame device includes a corresponding gas connection hose with all
the necessary safety fittings.
All high-performance rod burners are ignited conveniently from the driver’s cab. All burners can be individually ignited electrically at the push of a button. Thanks to our burner quick switch-off, which has been tried and tested for years, all burners can be switched off and on again in seconds when there are obstacles or young plants.
The floor guidance of the burner units on both sides is carried out by large, spindle-
adjustable steel support wheels (360/100 mm) that can be swiveled through 180°.
Thanks to the spindle adjustment, the height of the burners can be adjusted quickly, conveniently and optimally.
To prevent damage to the device, the left and right burner units automatically fold
backwards using horizontal parallelograms when approaching obstacles. Appropriate
gas pressure dampers ensure that the parallelograms are returned to their original position.
All of our flame devices have been tested and approved. They comply with the
current German technical regulations for liquid gas (DVFG-TRF).
Without Herbicides
The use of chemical agents to eliminate weeds is becoming increasingly complicated
and has been increasingly restricted in recent years. The legislature is planning even
greater restrictions, including a complete ban, in all areas in the coming years. The
flame-burning technique offers an interesting and effective way to eliminate weeds,
fungi and spores in an environmentally friendly way.
Outstanding Effect
Flaming technology is a practical, economical and environmentally friendly alternative
to weed removal. Chemical agents can be completely dispensed with.
The flaming ttechnology does not involve burning plant parts, but rather short-term
heating to at least 70 °C. From this temperature range onwards, the cell protein in the plant coagulates. The cell structure is permanently destroyed and a sufficiently large
number of cells die.
The plant cells are abruptly heated and killed via heat applied to the plant surface by
propane gas burners. The resulting rapid rise in temperature leads to such an
expansion of the cell fluid that the cell walls burst. Cell fluid leaks out and the plant
dries up.
Propane gas is used because it burns into carbon dioxide and water completely
without leaving any residue and in an environmentally neutral way!
Great Success
Before burning, the soil and the surface of the leaf masses should ideally be dry.
Basically the following applies: the younger the weeds, the more effective the
measure is. Success also depends on the time of use and the weather. This makes a
killing success of up to 100% possible.
Our unique high-performance rod burners achieve the highest flame temperature
possible with propane gas of approx. 1,925 °C. As a result, all parts of the plant that
are directly reached by the operating flame die immediately and with great certainty.
The operating flame is generated evenly across the entire width of the burner.
Subsequent rain has no negative impact on the success of a burning measure. This
does not affect the effect.
In order to heat all weeds to the required temperatures and achieve sufficient
damage, the following rule applies: the higher the exposure temperature, the shorter
the exposure time. Lower flame temperatures require a much slower working speed
and result in a correspondingly lower effect.
Time to use
1. Use:
The shoots that have grown back are torched with a burner approx. 2-3 weeks after the first plowing. The infestation of all pests and all fungal spores is also significantly reduced, as they die at temperatures above around 60 °C.
2. Use:
Here the Bifang is flamed with a burner approx. 2-3 weeks after the second plowing. The hop vines are also defoliated at the same time using a second, vertical burner.
