Apple Preparation System

Mod. C8A

Typical Installation

Purpose

The JBT Automatic Apple Preparation System is designed to peel,
stem, core and slice apples in a high speed continuous operation.

Product Uses/Applications

This Apple Preparation System is capable of handling multiple sizes
and varieties of fruit simultaneously and at random.

Features/Benefits

System designed for maximum yield

• Caustic / steam peeling section removes only the skin of the fruit,
leaving the valuable flesh for processing

• 7/16" (11 mm) diameter coring tubes are standard, which minimize
coring loss

• Self-adjusting seed celling knives adapt to the size of the individual
apple thus minimizing product losses

• Razor-like slicing knives virtually eliminate slice breakage

• Stainless steel construction ensures a sanitary design with a mini-

mum of maintenance.

Labor costs are reduced to a minimum

• High mechanical reliability and automated features reduce the need
for constant maintenance supervision. Only two attendants per
machine for fruit alignment

• Efficient seed-celling through the use of self-adjusting knives, practi­cally eliminates the need for seed-carpel inspection and trimming.

Operation

There are two basic sections to this apple preparation system, peel­ing and coring. The peeling section consists of a feed device, caustic
applicator, steam valve and peel remover/washer. The coring section
consists of a fruit aligner, corer-stemmer, seed celling and an optional
slicer.

Peeling

Apples are conveyed or flumed to the machine’s feed station where
they are shuffle-fed, eight across, and carried into a caustic applicator.
The fruit remains in the caustic solution for a pre determined time which
is variable. The holding period, density, and temperature of the solution
are set according to required peeling conditions. Emerging from the
solution, the fruit is then transferred to an elevator on which it is carried
into the high pressure steam valve. This activates the caustic solution
on the surface of the apple, thus loosening the peel. The holding period
and steam pressure in the valve are variable, depending upon the
condition of the fruit.
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.

Coring

Following the wash cycle, apples are either flumed or belt conveyed to
the aligning section of the coring unit. In applications requiring seed
celling, the capacity of the coring unit is 432 apples per minute. In
apple sauce operations where processors do not wish to seed cell, the
capacity of the coring unit is increased to 480 apples per minute.

The apples are fed, eight across onto a flight conveyor. Each flight is of
stainless steel and incorporates eight cups, each with an opening in its
center. An aligning wheel protrudes through , each opening rotating the
fruit to place it in a stem down or a blossom end down position ready
for coring.
The positioning of the fruit is further assisted by a vibrating action that
is applied to the flights. Two operators, one on either side of the aligning
conveyor, are sufficient to orient any fruit that is not properly positioned.

As the fruit passes under the coring tubes, centering rods assure proper
alignment on the vertical axis before the coring tubes enter the fruit.
The upper centering rods also remove the cores from the core tubes.
At a subsequent station, the apples are automatically measured
for length by the seed ceiling assembly, after which the seed cell is
removed by a live knife that self-adjusts for the depth of the seed cell.
The flight then travels to the slicing section where the fruit may be
halved, quartered or sliced by means of overhead knives from two to
fourteen pieces, after which they are discharged from the machine to
downstream processing. It should be noted that the only fresh water
used in the entire line is that introduced into the coring section.
