INDUSTRIAL PRODUCTION LINES
Baking Technology for the Industrial Production
of Durable Baked Goods
WP BAKERYGROUP
The WP BAKERYGROUP – with this corporate
portfolio, we have brought ourselves comprehensively into line with the requirements of bakeries
worldwide. Today, we are in a position to be
able to offer complete solutions – from project
planning to fitting out complete bakeries (trade
and industry), as well as supplying used machines.
A central element of our corporate philosophy is a networked thinking which spreads across all individual stages
of production. We call it “Process Management”, the targeted control of individual production stages and the machinery used – as fast as possible with the smallest possible loss
of materials to achieve the desired result, even with small
production volumes, as well as an unrestricted reproducibility of results that have been achieved. And all that with an
extremely high output.
Any unit can be “docked on” at any time if required for
manufacturing a product – there are adequate interfaces
for “foreign products”.

PRETZELS AND LYE BATH ARTICLES PRODUCTION LINES
Pretzels and lye bath articles production lines The process route for producing lye bath articles is started
by portioning the filling mass volume and the extrusion process. Cutting groups or biscuit moulding machine
comprise the following step. The final topping of the products is carried out in the lye bath which
incorporates a salt applicator and a cutting machine. The next stage is an SNK tunnel oven.
The number of oven modules is adapted to the required baking time in relation to the desired maximum
­capacity. The final transport to the packaging machine is carried out by cross and longitudinal belts, the
length of which is dimensioned to correspond to the required cooling time.
1The SP extruder is used for extrusion and filling mass portioning and intended to provide uniform dough
strands over the entire baking width. Filling masses are homogenised, temperature-controlled, filtered and
portioned and then guided to the extrusion head.
2The GH biscuit moulding machine is used for the production of a wide range of pretzels or cocktail
biscuits, simply by interchanging the moulding rolls. The machine is of a multipurpose type and suitable for
optimum biscuit moulding.
3.1Fresh and return dough are sheeted in the cut-out group and conveyed to the rotary cutting machine for
the production of small and large pretzels via special roll sheeters.
3.2Synchronised cut-out rolls are equipped with a special return-dough system.
4.1The moulded, cut or extruded dough pieces are passed through the temperature-controlled lye bath.
After this, the desired topping is applied.
4.2The dough strands are cut to length or grooved by a special guillotine. The transfer to the oven is carried
out on the basis of defined parameters and results in optimised loading of the baking belt.
5The SNK tunnel oven provides for an excellent development of the articles to be baked. Convection and
radiation can be ideally combined to obtain an optimum baking process.

AUTOMATION
Convenience of operation, reproducibility of product qualities at all times as well as a high availability of
the industrial production lines made by Werner & Pfleiderer are in direct proportion to their high degree of automation. Measurements and controls – all can be dealt with by one central computer, either
program-controlled or with the intervention of the operator of the production line. A great number of
various sensors are installed in pairs for safety reasons. Their operability is checked by the system itself.
The sensors consistently monitor the parameters affecting the quality of manufacturing process, such
as for instance dough quality and output, height of bulges, sheet width and speeds, oven humidity and
temperature, product moisture content and temperature. Their measuring results directly influence the
settings on the line modules – a completely self-regulating system. The whole manufacturing process
is documented in every detail and can be traced on product line and host level by persons with the
relevant authorisation and adjusted manually, whenever necessary. The entire automation system can
be monitored or serviced remotely by way of internet access.
