Conveyors

Pohjaranta designs and builds stainless steel conveyor systems for crates, crate stacks, bins and roll containers. Every conveyor is sized to the product, the line rate and the layout, and the frames are made of stainless steel for the washdown areas of food, beverage, bakery and logistics operations. The range covers belt conveyors, chain conveyors and roller conveyors, and complete lines built from them.

Roller conveyors and accumulation conveyors

A roller conveyor is the natural choice for crate stacks and heavy units. On the accumulation roller conveyor, low-friction rollers let crates and stacks stop and queue while the drive keeps running, so the conveyor works as a buffer between line stages. Standard size is L2900 × W420. See Accumulation Roller Conveyor.

Belt conveyors

We build belt conveyors with modular belts and round belts. A modular belt conveyor suits food products and single crates, with the belt type and width chosen for the application. The compact C-Conveyor and the belt-driven side transfer for single row washing lines are examples of belt technology in Pohjaranta lines.

Chain conveyors

A chain conveyor carries heavy stacks and pallets and keeps crates accurately on track. Chain drive is used in the stack feeding conveyor, the side transfer for two row washing lines and the pallet conveyor. Plastic chain conveyors, such as the shopping basket conveyor on Uni 1702 chain, suit lighter loads and tight curves.

Flat wire belt conveyors (wire mesh belt)

The stainless steel wire mesh belt lets water, soil and heat pass through, which makes the flat wire belt conveyor the natural choice inside washing lines, dryers and cooling sections. Mesh density and loop size are matched to the product.

Curve conveyors and C-conveyors

The curve conveyor turns the flow in tight spaces: the plastic chain model allows tight radii for lighter loads, while the roller model carries crate stacks. The C-Conveyor routes crate flow along a C-shaped track at washing line in-feed and out-feed stations.

Storage and buffer conveyors

The storage conveyor buffers crate stacks, bins and tubs close to the point of use, giving the line a steady infeed without forklift traffic. Widths range from 300 to 1300 mm and lengths up to 25 m, and pneumatic stoppers dose the load forward in a controlled way.

Roll container, shopping basket and crate conveyors

The roll container conveyor moves roll containers on chain or roller technology, with guides and stops for positioning. The shopping basket conveyor carries baskets of several sizes on the same track without changeover parts. The crate conveyor moves single crates between line stages at 100–800 mm/s.

Dosing, merging and side transfer

The dosing conveyor transfers crates from one conveyor to another with roller chain technology at up to 2,000 crates per hour. The stack feeding conveyor merges two or more stack flows into one queue at the washing line infeed. Side transfers move crates across onto single row and two row washing lines, and junction and divider units let the line branch and merge.

Pallet conveyors and vertical conveyors

The pallet conveyor moves EUR pallets on chain or roller conveyors, and the two-row chain model carries pallet loads up to 1,000 kg. The vertical conveyor lifts crates from one level to another in a small footprint, with side transfer or a roller conveyor where needed.

Hygienic conveyor systems from design to commissioning

Stainless steel frames stand up to washdown in food conveyor applications, and frequency converter speed control lets the conveyors run in step with washing lines, stackers, destackers and transfer carts. Pohjaranta has designed and manufactured conveyor systems at its own factory in Säkylä, Finland, since 1992. Engineering, mechanics, automation, installation and service are done by our own people, and a delivery can be a single conveyor or a complete line with PLC control.
