Chapter 4 CLEANING ROUTINES
Miris Cleaner™ and emery cloth are necessary for proper maintenance of
the instrument.
REQUIRED CONSUMABLES
MIRIS CLEANER™
Description: Cleaning agent (liquid concentrate).
Application: For cleaning of the Miris Ultrasonic Processor probe and
surfaces.
Storage: Store the concentrate dark, at room temperature (20-30°C), sealed
in the container in which it is supplied. Store the diluted solution in glass or
plastic containers, out of direct sunlight. Keep away from foodstuff and animal
feed.
Instructions: Dilute 50 ml concentrate (1 tube) with 950 ml distilled or deionized
water and mix. Follow the instructions in the section Cleaning of the instrument.
The estimated time for preparation is 5 minutes for mixing the ingredients. The
ready to use dilution should have a faint odour (soapy, chemical) and no colour.
Materials provided: Materials required but not provided:
Liquid concentrate in 50 ml container 1000 ml glass or plastic container
950 ml distilled or deionized water
Do not use if the liquid is cloudy or precipitations are visible.
Use before: Expiry date for unopened tubes is 1 year from production date.
Use solution within 3 months of preparation.
Environment and health: Small spillages may be ushed away with plenty
of water to a drain or sewer. Miris Cleaner™ is biodegradable. Ready
biodegradability by OECD 301E (ISO method 7287 - 1986(E)).
Non-hazardous. In case of contact with eyes, rinse immediately with plenty of
clean, owing water. Seek medical attention if there is persistent irritation. In
case of contact with skin, rinse immediately with plenty of clean, owing water.
If ingested, drink copious amounts of fresh water and seek immediate medical
attention. Do not promote vomiting.
EMERY CLOTH
Description: Fine grit emery cloth.
Application: For polishing the Miris Ultrasonic Processor probe tip.
12 | CLEANING ROUTINES Miris Ultrasonic Processor User Manual
Page 13
CLEANING OF THE INSTRUMENT
To maintain the homogenisation efciency of the Miris Ultrasonic Processor, it
is important to clean and polish the probe after each use. Homogenisation ef
ciency is determined by the capability of the probe to transmit energy into the
milk, and this capability will degrade in proportion to the degree of roughness of
the tip surface. Any erosion of the probe tip, visible as dark spots or a ring round
the outer edge of the tip, must therefore be removed by careful polishing with
ne grit emery cloth. Polish off the eroded part only and no more, or the probe
will wear out quicker.
-
PROBE CLEANING
Wipe off the probe after every milk sample using a tissue.
Clean the probe with a cloth dampened with Miris Cleaner™ after nishing for
the day.
Polish the tip (the at end) of the probe with an emery cloth after each use.
Make sure to polish the probe evenly, avoiding bevelled edges, and to complete
ly remove any milk residues, see Figure 5.
-
Figure 5. Polished probe tip.
INSTRUMENT SURFACE
Wipe spillages immediately. Clean the instrument surface and inside using a cloth
dampened with Miris Cleaner™.
If necessary, a mild disinfectant can be used to clean the probe and the instrument
surfaces.

WORKING PRINCIPLE OF THE INSTRUMENT
PRINCIPLE OF OPERATION
The power supply converts 50/60 Hz voltage to high frequency
energy, which is transmitted as mechanical vibrations from the
converter. The vibrations are intensied by the probe and make
the probe tip oscillate in the length direction, creating pressure
waves. Due to these pressure waves, microscopic air bubbles are

created and disrupted within microseconds, a phenomenon called
cavitation. When the air bubbles disrupt, the release of kinetic
energy will break large fat globules into smaller ones. Small fat
globules have less creaming tendencies and stay homogenously
distributed in the milk.
MILK HOMOGENISATION
Fat and proteins are the main structural elements of the milk
system, and their chemical characteristics affect the milk as a
solution. Milk fat is considered an oil-in-water emulsion, with fat
droplets covered by a hydrophilic membrane. The milk proteins
are a colloidal solution or dispersion in the milk plasma. Time,
temperature and gravitation are some parameters that affect
the chemical characteristics of these components, i.e. the milk
fat will separate when allowed to stand, known as creaming [1].
Creaming of milk fat is faster at low temperatures due to cold
agglutination [2].
Miris Ultrasonic Processor homogenises the milk using the
cavitation phenomenon. Cavitation is the formation and collapse
of air bubbles caused by pressure uctuations. The collapse of air
bubbles releases shock waves, causing damage to the surrounding
particles [1]. The energy output from the Miris Ultrasonic Processor
is approximately 20 J/s per ml of milk.
In milk, cavitation causes disruption of milk fat globules into smaller ones, and proteins are adsorbed onto the fat droplets, which
improves the stability of the fat globules [1]. Ultrasound is more
efcient when combined with heating [2].
