Pear Preparation System

Mod. C8P

Typical Installation

Purpose

The JBT C8 Pear Preparation System is designed to peel, stem, seed
cell and optionally slice pears, in a high speed, continuous operation.
The System can be used interchangeably for canned cocktail and
sliced pears.

Benefits/Features

Low Operating Costs - result from the substantial reduction or
complete elimination of the need to pre-size the pears. Self adjusting
flights and coring knives used in this System handle practically all
sizes of pears, at random, with maximum yields.
Only two attendants are required to check fruit alignment, thereby
saving most of the feed labor required with hand-fed knife peelers.

Maximum Yield - is achieved by caustic peeling, by which means
only the skin is removed from the fruit. This technique eliminates
the peeling away of the flesh, which is a characteristic of live knife
techniques. Precise, self adjusting coring knives also contribute to
maximum yield.

High Quality - results from the fact that only the skins are removed,
leaving the shape of the fruit in its natural contour. The coring knives
also remove unsightly and tough textured stem fibres and seeds.

Construction/Operation

The C8 P System consists of four (4) components as follows:

• Caustic Applicator

• Transol* Steam Valve

• Peel Remover / Washer

• Coring Section which includes aligning, coring, seed-celling, and
slicing.

In operation, pears of uniform ripeness are conveyed to the machine’s
feed station where they are shuffle-fed into a caustic applicator. The
fruit remains in the caustic solution for a predetermined time which is
variable. The holding period density and temperature of the solution
are according to required peeling conditions. Emerging from the
solution, the fruit is transferred to an elevator which carries it into a
high pressure steam valve (Transol *). The steam pressure is easily
adjusted by setting indicating controller.

Upon completion of this steam exposure cycle, the fruit is discharged
to a rotary rubber cord washer that removes the loosened skins from
the fruit.
The washer employs an internal spiral which moves the fruit gently
through the drum as it rotates. The walls of the drum are constructed
of molded rubber cords spaced at 1” (25.4 mm) centers.

The softened peel is removed from the fruit by the combined action of
rubbing against the rubber cords and other pears. Approximately 95%
of the peel is removed in the first half of the washer and drops through
the rubber cords to a chute where it can be collected and removed as
a solid waste. In the second half of the washer 10-12 gpm (38-45 l/
min.) of water is used to rinse any remaining lye from the surface of
the fruit. This water is kept completely separate from the solid waste
material.

CORING HEADS remove cores and stems from pears held stem down
in individual cups. Seed celling and slicing steps follow.

From the washing section, the peeled pears are flumed or conveyed to
a shuffle-feeding device that meters them into the aligner.
The aligner gently drops the fruit, 8 at a time, onto the coring section
conveyor. Each flight has 8 plastic cups which are formed to accept
the fruit in a stem-down position.
An orifice is provided at the bottom of each cup for refuse removal.
The cops are in an open position as the fruit is fed into them.
Upon receipt of the fruit, the cups automatically adjust to the fruit
size and close sufficiently to cradle it, thus placing the fruit in proper
alignment for coring and stemming operations.
Two operators, one on either side of the aligner conveyor, are
sufficient to orient any fruit that may be off center.
The conveyor operates continuously at the rate of 50 flights per
minute, giving a total through-put of 400 pears a minute.
Indexing with the travel of the flight conveyor is a coring/stemming
section.
As each flight enters this section, stemming tubes enter the inverted
pears at the butt end and discharge the stems through the orifices of
the plastic cups.
At a subsequent station, in this same section, the pears are
automatically measured for length by the coring assembly after which,
the core is removed by a live knife that self-adjusts for the depth of
the core.
The calyx cut is made simultaneously and the refuse is flushed out of
the fruit by a water spray.
The flight then travels to the slicing section where the fruit may be
halved, quartered or sliced by means of overhead knives.
In a cocktail operation, the fruit is generally left whole.
Most processors provide for final trimming and inspection after the
coring section.
