3.1 Description of the machine
Thismachine has beendesigned and constructed
to provide reliability and safety when used for a
wide range of applications.
The automatic machine FRUIT FEEDER2000
iscapable of feeding continuouslypieces offresh
fruit, candied fruit, granular products such as
hazelnutsandnougat, chocolate and awide range
of products normally used for ice-cream
production.
Designed as a stand-alone unit, it is normally
installed on ice-cream production lines between
a continuous freezer and a filler machine.
Toputintoservice, simply hook it up tothe mains
power supply and connect to the freezer and the
filler
machine.
The FRUIT FEEDER 2000 consists of three
mainunits:
1. Adosingunit,consistingessentiallyofa main
hopper, a screw feeder and a secondary
hopper.
The ingredients are fed manually by the
operator into the main hopper and then move
under gravity towards the bottom of the
hopper, where a horizontal-axis screw feeder
is situated. As they descend, the ingredients
are mixed continually by a slow agitator,
which ensures a constant flow of product to
the screw feeder. The screw feeder feeds the
ingredients into the secondary hopper from
where, again under gravity, they are fed to
the pump unit.
2. A pump unit, consisting of a vane pump
(Pos.2, Fig.3.1) which serves to feed the
ingredientsinto the flow ofice-cream coming
from the continuous freezer.
The vane pump consists of a rotor containing
radialvanes which are guidedbyan eccentric
guide machined inside the casing.
The pump also serves a function as a
separating seal between the pressurised ice-
cream line and the external environment so
asto allow a one-wayflowofingredientsfrom
the secondary hopper to the ice-cream.
3. An in-line mixer (Pos.3, Fig.3.1), consisting
ofashaftwithangledbladespositioned inside
the section of pipe downstream of the pump
unit. This unit serves to provide intensive
mixing of the product with thr ice-cream
before it goes on to the filler machine.
Themachine has been constructedtointernational
standards and to health and sanitary regulations
applicable to food machinery. In particular, Te-
tra Pak Hoyer S.p.A. certifies, through the
Declaration of Conformity provided together
with the machine, that the Fruit Feeder 2000
has been designed and constructedin conformity
with the Directive 89/392/EEC (Machinery
Directive) and with the applicable above-
mentioned standards.
The machine has an entirely stainless steel
structure and is mounted on wheels. All parts
directly in contact with the product are made
entirely of stainless or aseptic material and are
polishedinternally.
Inorderto avoid accidental contact betweenparts
of the operator’s body and moving machine
components, the machine is fitted with panels,
guarding and covers fixed by means of screws
and/or systems that in any case require the use of
special tools and deliberate action on the part of
the operator to be removed.
Only the lid of the main hopper can be raised
without the use of special tools to allow the
operator to feed in the ingredients. A safety grid
prevents the operator from accidentally coming
into contact with the slow agitator of the hopper.
Opening the grid activates a microswitch which
causes the machine to stop immediately.

Fig.3.1
The ingredients are fed manually by the operator
into the main hopper (Pos.1, Fig.3.2). Access to
the main hopper is gained by tilting back the lid
(Pos.2,Fig.3.2). Thesafety grid (Pos.3, Fig.3.2)
must only be removed for maintenance work
when the machine is turned off.
The ingredients are kept continually moving by
the slow agitator located in the upper part of the
main hopper; they arethen fed into thesecondary
hopper by means of the screw feeder (Pos.4,
Fig.3.2) located on the bottom of the hopper.
The screw feeder is made of aseptic material and
is available in various versions according to the
type of ingredients to be fed. The speed of the
screw feeder and the slow agitator are variable
and can be regulated by the potentiometer on the
control panel. As a consequence, the flow rate
of ingredients can also be continually varied.
From the secondary hopper the ingredients are
Fig.3.2
3.2 Operation
fed under gravity towards the inlet port of the
vanepump(Pos.5, Fig.3.2) locatedon the bottom
of the secondary hopper.
Theyare then fedinto the cavitycreated between
twoadjacent vanes as a result of thespecialprofile
of the eccentric guide.
Duringrotation the ingredients comeinto contact
with the ice-cream through the discharge port
located on the bottom of the casing. This way
the ingredients are fed into the ice-cream flow.
The rotor is mounted on the reduction gear
output shaft and its speed of rotation can be
regulated from the potentiometer on the control
panel by means of a frequency converter
connected to the gearmotor.
The mix obtained is fed to the vertical mixer
(Pos.6, Fig.3.2), which serves to mix the ice-
cream and the ingredients and hence obtain a
uniform and well-mixed product.

TheFRUITFEEDER2000mustbesituatedas
closeaspossibletothefillermachineforthe
followingreasons:
a. The pressure of ice cream reaches its lowest
value at this point.
b. The ingredients fed in tend to be deposited
on the layer of ice-cream in contact with the
pipe. Therefore a smaller distance between
themixer and thefiller machine willgive rise
to a more uniform distribution of the
ingredients in the ice-cream.

4.3 Functionalchecks
to start the motors. Lift the secondary
hopper lid (Pos.3, Fig.4.7) and check that
the vanes turn anticlockwise (Pos.4,
Fig.4.7). Check, by viewing from above,
that the in-line mixer turns anticlockwise
(Pos.5, Fig.4.7). To carry out this check,
disconnect the 2” to 1 1/2” reducer. Be
particularly careful not to crush parts of
your body during rotation of the mixer
baldes. Press the luminous button (Pos.7
