AgroVent Storage Systems

AgroVent is a Dutch company that started back in 1992 to meet the market demands for better, more efficient crop drying and storage through condensing methods.  AgroVent systems can be seen all around the world and Dobmac are pleased to be the Australian and New Zealand distributor.

Limitations with current methods such as air drying and gas heating has led AgroVent to develop the VaccTek system.  The VaccTek system allows produce to dry independently of the exterior climate conditions, which is becoming increasingly important with the unpredictable weather and push for organic products.

Gas heating, currently the most common method, is costly and inneficient, for every 1kg of gas burned, 1.6kg of water is produced, therefore 10% of gas consumption is used to remove the moisture created by the combustion.  The VaccTek system when compared to the gas drying method produces 50% shorter drying times and uses up to 80% less energy.

Moist air from the store in drawn in and guided along the condenser, stripping the moisture, as the condensation process cools the air, the air is then passed through a heat pump to produce a stable 14-16 degrees before being blown back into the store.  The VaccTek also has the ability to utilise exterior air when conditions are favourable meaning further efficiencies

The VaccTek system is placed half in/ half out of the outter wall, all that is required for fittment is a strong, stable floor. 

  • A single unit contains fans, cooling, condenser dryer and the exhaust shutter.
  • Drying capacity- 30-70kg water per hour and 10-16 degrees celsius
  • Cooling Capacity- up to 0.7 degrees celsius / 24hr
  • Ventilation- approx 75,000m3 / hour, frequency controlled.

Wifo K95 Forward tipping box rotator

You can now pick up boxes from a row or place them up against each other with a forward tipping box rotator. A produce and box friendly rotator with a unique tipping mechanism which leaves the sides of the box completely free. 

The current forward tipping box rotators still have a tipping mechanism at the side of the box, but the new WIFO K95 forward tipping box rotator has a unique tipping mechanism located at the rear with two extending curved profiles.  Becuase the tipping mechanism is located behind the box, the sides remain completely free making it possible to place the boxes against each other easily.  It also only requires only one forklift to handle the boxes.

The box rotator can be used in many ways. It has a wide tipping angle of 150 degrees and a maximum load capacity of 2,500 kg.

The machine is fitted with an upper clamp and in the case of standard potato boxes (1600 mm wide) the clamp ends up exactly on the edge of the box so that the top of the box is completely unobstructed and the products can come out of the box easily. The box is clamped securely, which means that it will suffer little or no damage.

When the clamp is completely open, it is possible to pick up several empty boxes. The use of a sequence valve makes it possible to empty out the boxes in a controlled and careful way.

The K95 is normally supplied for forklifts but is also suitable for any type of telescopic handler.
