3.1 Description of the machine
This machine has been designed and constructed
to provide reliability and safety when used for a
wide range of applications.
The automatic machine FRUIT FEEDER 2000
is capable of feeding continuously pieces of fresh
fruit, candied fruit, granular products such as
hazelnuts and nougat, chocolate and a wide 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.
To put into service, simply hook it up to the mains
power supply and connect to the freezer and the
filler
machine.
The FRUIT FEEDER 2000 consists of three
main units:
1. A dosing unit, consisting essentially of a 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
ingredients into the flow of ice-cream coming
from the continuous freezer.
The vane pump consists of a rotor containing
radial vanes which are guided by an 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
as to allow a one-way flow of ingredients from
the secondary hopper to the ice-cream.
3. An in-line mixer (Pos.3, Fig.3.1), consisting
of a shaft with angled blades positioned 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.
The machine has been constructed to international
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 constructed in 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
polished internally.
In order to avoid accidental contact between parts
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.
