near the connection.
Mains Water: The mains water supply is connected to a 1 1/2” pipe located at the
rear right side of the machine (see Figure 2). A shut off valve should be provided
at or near the connection.
Chilled Water: The chilled water supply is connected to a 1 1/2” pipe located at the
rear right side of the machine (see Figure 2). The chilled water return is connected
to a 1 1/2” pipe located above the chilled water supply connection. A shut off valve
should be provided at or near the connections.
Steam: The steam supply is connected to a 1-1/4” pipe located at the rear right
side of the machine (see Figure 2). A shut off valve should be provided at or near
the connection.
Waste Drain: The waste drain is connected to a 2” pipe located at the rear bottom
right side of the machine (see Figure 2).
EQUIPMENT DESCRIPTION
The CapKold Model CKTC-320 batch tumble chiller will chill up to 300 gallons of
bagged product. The machine is stainless steel construction throughout with a
perforated stainless steel basket. An inclined loading chute allows continuous
loading of product while the basket is in motion.
The touch screen control provides easy operator interface, with simple custom
programming.
The drive system consists of a variable speed 1 HP motor and a selectable
reversing function for improved tumble action while chilling and a manual jog for
distribution while unloading. Power transmission to the cylinder is performed by a
direct drive gear box to achieve smooth operation.
The door is locked and sealed manually and may not be opened while the tumble
chiller is operating. This interlock also requires that the door be shut and sealed
prior to starting.

STANDARD FEATURES AND COMPONENT DETAILS
Gear Motor Drive with Inverter: The machine includes a 1 HP single motor drive and
AC variable frequency inverter. This arrangement provides precise speed control
of the inner basket between 2 and 8 rpm’s through a gearbox motor mounted
directly to the basket’s main shaft. The basket rotation options include one way,
oscillate and gentle. The energy efcient motor is rated for continuous duty. The
inverter is safely mounted in the electrical cabinet.
Front Door: The front door includes an inclined loading chute to allow continuous
loading of product while the basket is in motion. Pneumatics are used to seal/lock
and unlock the door.
Heat Exchanger: The chilled water source is pumped through a high heat transfer
coefcient plate heat exchanger.
Leveling System: A leveling system consisting of four adjustable legs. No special
foundation is required other than a oor with the capacity to hold the static weight
load of the machine, water, and products contained within.
Bearing Design: A shaft mounted ange bearing design and integrated bearing/
motor/gear box supports the cantilevered load of the inner basket. The front and
rear bearings are sealed ball bearings and do not require grease.
Seal Housing: A housing containing a spring loaded ceramic seal keeps water and
chemicals contained in the machines shell from leaking out, while allowing the
machine’s main basket shaft to rotate freely. The ceramic seal is lubricated with
water and the basket will not rotate without the centrifugal pump turned on or
without the mains ll open.
Mains Water Inlet Valve: The water inlet valve is pneumatically operated, 1 1/2”
buttery type, and is closed by spring pressure.
Chilled Water Inlet Valve: The water inlet valve is pneumatically operated, 1 1/2”
buttery type, and is closed by spring pressure.
Steam Inlet Valve: The steam inlet valve is pneumatically operated, 1-1/4” buttery
type, and is closed by spring pressure. The standard machine is outtted with
one valve for direct steam injection into the bottom of the shell through a diffuser
nozzle. Steaming does not occur until the water level has been satised. If no
steam is available, hot water supply can be used and must be programmed in the
formula.
Drain Valve: A pneumatically operated, 2” buttery type valve mounted below the
outside shell allows for rapid gravity draining of waste water.
Automatic Back Flush: An automatic back ush of the heat exchanger will back
ush build up of foreign matter which has entered the heat exchanger in order to
maintain optimal heat transfer between chilled water and product.
In-Line Filter: An easily accessible in-line lter provides protection for the pre piped
centrifugal pump in the event a plastic bag breaks open.
Touch Screen Controller: A PLC-based, Operator Interface Terminal with a
graphical touch screen provides the formula control for the machine. It provides
a storage capacity for up to 99 formulas, up to 99 events (steps) per formula, and
99 product codes. Functions include step time, rotation intervals and speed, water
addition and draining, temperature control, chemical and steam injection, door
operation and safety interlocks for the protection of the operator and machine.
The OIT connects to the machine’s PLC allowing multiple input/output capability,
while providing the operator and maintenance personnel with an easy to program
control system.
