Producers of yoghurt with various flavours are familiar
with the situation of having to carry out several product
changeovers every day and they know the special challenges
in order to reduce product loss and machine downtimes
to a minimum. With the inline fruit mixer Grunwald has developed
an intelligent and innovative solution to meet these challenges.
When this inline fruit mixer was developed special attention
was paid to keep the product feeding pipework as short as possible.
The inline fruit mixing reduces the mixing process to a minimum
in case of a flavour change and thus considerably reduces
the loss of fruit which is an important issue. In addition the change
between the different types of fruit can be carried out much more
quickly. This means “reduction of the cost of products and increase
of productivity at the same time” for the producer.
This inline fruit mixing technology is economically advantageous
especially for machines filling yoghurt with fruit layer. In
order to fill yoghurt with fruit layer a pre-filler for fruit as well as a
main filler for stirred natural yoghurt is used.
To produce stirred fruit yoghurt on such a machine the prefiller
is used as fruit dosing pump which accurately feeds the fruit
preparation cycle by cycle to the filling station for the stirred natural
yoghurt. The inline mixer equally mixes the fruit preparation in
the yoghurt. The percentage of fruit preparation can be changed
on the operator panel of the cup filling machine. The modified
values are automatically stored in the recipe control. The changeover
from filling yoghurt with fruit layer to the filling of stirred fruit
yoghurt is either carried out manually within approx. 5 minutes or
in fully automatic operation by the push of a button (or: via the
touch panel), depending on the specification of the machine. The
customer can choose from very simple and low budget design up
to fully automatic CIP/SIP design.
This technology is dedicated for being used on flexible rotarytype
and linear machines with frequent change between various
types of fruit and for production speeds of up to 12,000 cups/h
and for filling up to 6 types of fruit. The advantages compared
to stand-alone fruit mixers are low investment costs and it is
verifiable that the production costs are reduced, and the flexibility
is increased.
