Operation
Pre-Startup Check
These instructions are general and should be used only as a
guide. It may be necessary to modify them to conform to
actual in-plant requirements. Changes should be
documented by plant personnel.
Before starting Votator II, perform the following system
checks:
WARNING: Do not operate equipment without
guards and interlocks properly installed.
• Check that Votator II is properly assembled. All
product connections, and heating/cooling media
connections should be assembled and tight.
• If steam or water flush is required for mechanical
seals, open supply valve and set pressure and flow
rate.
• Momentarily start motor (1-3 seconds) to determine if
shaft is rotating. If shaft is not rotating, turn off power
to motor and determine why shaft will not turn.
• Check heating/cooling media to determine if
temperature and pressure are at required values and
there is an adequate supply of heating/cooling media.
• Check to determine if product is available and
pressures are at required values.
For Refrigeration Units Only
• Check that main suction line is fully open.
• Check for proper compressor back pressure.
• Open liquid refrigerant supply valve, turn system
refrigerant on and verify that accumulator is full to
float level.
Pre-production Run Setup
NOTE:
The following steps are not applicable to aseptic
units, which require special sterilization procedures.
The interior of the Votator II heat exchanger tube, mutator
shaft, heads, and product piping leading to the unit should
be sterilized before running product.
Use sanitizing solution compatible with the materials of
the Votator II. If a chlorine solution is used, it must not
exceed 50 ppm at 75°F (24°C) and surface contact must be
limited to 10 minutes.
CAUTION: The Votator II has not been
passivated as part of the manufacturing process.
If the heat transfer tube is chrome plated nickel,
DO NOT expose to acid or acid cleaners .
Startup Procedure
Heating/Liquid Cooling Applications
1. Start product pump using product or compatible
liquid, such as water.
2. After product flow is established, start Votator II
mutator shaft motor. Do not run Votator II without
product flow.
3. Establish operating pressure.
NOTE:
Maintain an operating pressure that will result in
desired product characteristics. In heating applications,
operating pressure should be at a minimum of 15 pounds
above jacket steam pressure. This will eliminate internal
boiling and fouling of product side of heat transfer
cylinder.
4. Gradually admit dry, saturated steam or coolant to
reach system operating temperature. For steam units,
open steam valve and immediately open bypass valve
at trap to drain condensate. Close bypass valve after
all condensate is drained.
5. If running material other than product, switch to
product and adjust to desired processing rate.
6. When operating conditions have been reached,
redirect product to desired out-flow point.
STARTUP SUMMARY
LIQUID/STEAM
Establish seal flush flow (if required).
Check media availability.
Start product or water flow.
Start mutator shaft.
Establish operating pressure (if required).
Admit steam/coolant flow.
Switch to product flow (if necessary).
Adjust media for desired product temperature.
Redirect product flow (if necessary).
