Multilevel Belt PFRBuffering and cooling of delicate products

PFR (Product Flow Regulation) and buffers

processes and depend on the available space.

Performance data

The Multilevel Belt Product Flow Regulator (MLB PFR) is

mainly used for unpackaged products: Next to marshmallows,

biscuits, sticky cereals and fruits bars, it can handle a wide

range of products. It can optionally be built in a „wash-down“

execution which suits in particular products whose transport

can contaminate the belt and where a time gain for cleaning

has a high priority. This MLB PFR does not only take over the

regulation of the product flow, but can also be used to cool the

products after baking and to empty the oven.

Scope of application Customer benefit

The MLB PFR allows regulating the product flow of delicate and

sticky products, too. It can be used for product flow regulation

and / or for cooling. The productivity can be considerably raised

with a PFR. End rollers with small radii allow the handling of

small products. The MLB PFR is of modular design and can

ideally be adapted in the available space. Long cooling tunnels

or expensive structural adaptations of the building can there-

fore be avoided.

The MLB PFR is extremely maintenance and cleaning friendly.

The low technical complexity allows easy operation. A smart

control unit indicates the different levels to ensure an optimum

filling of the PFR. Not only is a maximum capacity reached, but

also an optimized Overall Equipment Effectiveness (OEE).The incoming products are inspected and misaligned rows can

be rejected. The products are grouped into batches without

pushing or touching each other. They are placed on a lifting belt

which loads them, one after another, onto the different buffer

levels. As soon as the product flow permits to pursue the trans-

port, and when the defined dwelling time has been reached, the

products are lead in groups to the outfeed belt and, if necessa-

ry, are brought anew in a continuous product flow. The product

loading and unloading can be done with different speeds. Since

the products are neither pushed nor touched, this concept is

ideal for delicate and sticky products.

Function principle

1 Batch preparation: Row inspection and product grouping 2 Product elevator: Feeding of the different cooling/buffer levels 3 Product cooling: Product infeed (back) and cooling/buffer zone (left) 4 Execution type: Wash-down execution optional
