Demtec EVO2

Demtec's best potting machine yet, this filler should be the standard potting machine for everyone working with pots from 6 up to 27 cm (2.4” to 10.6”). The machine is easily adjusted and is equipped with a full-automatic soil dosing system. The wide potting ring offers enough room for pots up to 27 cm (10.6”), and is easily transported around the nursery thanks to pneumatic tires. For the tree nursery, the machine has a soil hatch that releases substrate on to a rotating middle disc. A pouring edge can be made which is ideal for mulching (e.g. bark).

Improvements on previous model

  1. The chassis has two front air tires, positioned wider, to improve stability. Two swiveling coasters on the back make the machine maneuverable. A detachable tow bar is optional.
  2. The tub and turntable has been adjusted for more stability in high speed settings (at 4200 pot/hour it still runs smoothly). The height of the tub has also been lowered for better ergonomics. 
  3. More space created for the evacuation soil coming from the drill and the soil return system has been redesigned to help run the machine with specific soil compositions such as coco fiber soil and clay (for example) easier.
  4. The soil feed belt now has the flexibility to run backwards if something jams or if the grower wants to change the kind of soil. The automatic soil regulation system has a selector to place the settings of the system for small and big pots. 
  5. The central adjustment system is a very important feature of the EVO2 where center rods are used to enable you to work with a fixed drill position. 
  6. The central switch box has been moved to improve accessibility and create more space for the pot feeding belt. Some instruments are now placed over the turntable on a pivoting arm. 
  7. Standard pot de-stacker will be the DTC2B pot de-stacker and will be mounted (standard) on the front plate with a pivoting pot-feed belt. The pot ejector is equipped with a new safe guard.

Additional Information

  The Demtec 3016 is an incredibly versatile potting machine, and will give years of reliable service. Capable of working automatically with pots from 7 cm to 26 cm and 26 cm - 35 cm, it benefits from a solid chassis and a large 3000 L hopper. The potting machine comes with 8 and 16 station potting rings, with centralized adjustments - making changes between different pot sizes quick and simple. Large pneumatic tires and a towing arm makes easily mobile, and comes standard, with a pot dispenser, automatic pot take-off arm and wide exit conveyor. The Demtec 3016 has an easily adjusted 'pneumatic' double-sided pot dispenser, which is exceptional with second hand pots (if you reuse them). The strong linear pot take-off arm has a very smooth action and allows pots to be removed onto the wide take-off conveyor with little effort. The 3016 is equipped with a wide conveyor and additional rollers for smooth running have been added for use with larger pot sizes. Unique features include a system in the soil hopper to prevent 'soil bridging' and a soil return conveyor eliminating overfilling of the soil elevator. Bare root potting is also easy, as the 3016 comes supplied with the bare root system - allowing pots to be part filled and then topped up from center spilled soil after the shrub is placed in the pot. This model is standard 3-phase but a phase converter can be used if 3-phase is not available at your location.

 There is potting work that must be done with great care: trees or large plants must be taken out of the ground and be put in containers, or large plants must be transferred from one container to another.  One often seems to think that this can only be done by hand.  Therefore, Demtec has developed a slow-turning machine that turns this heavy potting work into an automated activity. The standstill time of the machine is infinitely variable so the time for the secure planting can be freely determined.  Also the intermediate distance between the pots is chosen. With a 5016 the limits of a classic potting machine are opened up.

 The Willburg Projecten Bark Topper is a system that rotates the pots at a predetermined speed to evenly distribute bark, nut shells, rice hulls or any media to your required depth. The Bark Topper has 7 variable speed motors that enable you to individually control speed, rotation, and material flow at rates at up to 5000 pots per hour. A photo eye starts and stops the machine allowing for minimum recycling of media and precise distribution without having to vibrate the pot. The machine is of solid, durable construction built to give many years hard service. Topping your pots will prevent weed growth and moss formation, giving a good presentation, saving time and money at shipping time.
