Mixers commonly are divided into gas and low viscosity liquid mixers (
Ribbon mixer), high viscosity liquids and-paste mixer, thermoplastic materials mixer , Powder and granular solid materials mixer.
The characteristics of
gas and low viscosity liquid mixers is simple structure, with no
rotating parts, a small amount of maintenance repair ,low energy
consumption. this type machinery is divided into air mixing, channel
mixing, jet mixing and enforcement cycle, and so on.
high viscosity liquids
and-paste mixer , generally have strong shearing; thermoplastic
materials mixer for thermoplastic materials (such as rubber and
plastics) mixed with additives; powdered and granular solid materials
mixer more mixed For the intermittent operation, including both mixed
and the role of the grinding machine, such as the wheel rolling machine,
and so on. Mixed asked to participate in all the materials mixed evenly
distributed. The degree of mixing is divided into the ideal mixture,
mixing random and completely no mixture three states. The degree of
mixing of a variety of materials in the mechanical mixed, depending on
the ratio of material to be mixed, physical characteristics and, as well
as the use of mixed type and mixed Machine operation duration, and so
on.
The liquid mixture
mainly rely on mechanical mixers, air and liquid jet to be mixed, and so
on, so that to be stirred by mixing materials to achieve uniform
mixing. Stir caused by some of the liquid flow, and promote the flow of
liquid around the liquid, resulting in the formation of soluble inner
circle flow, the resulting liquid known as the spread between the main
convection-diffusion. When the stir caused by the high rate of liquid
flow, the flow of high-speed and low speed flow around the interface
between the emergence of shearing, resulting in a large number of local
vortex. These rapid swirl around proliferation, but also more liquid
into a whirlpool in the past, in a small area of the formation of
convective disorder known as the spread of eddy current proliferation.
Classification of Mixer(2) Mechanical moving parts of the blender in the
rotation will also produce shearing of liquid, liquid flows through the
wall and the installation of container in the fixed component, would
also be cut, which would give rise to a number of shearing The
proliferation of local vortex. Stir the main cause of the
convection-diffusion and spread of eddy current, an increase of liquid
between the different elements of the proliferation of surface area to
reduce the spread of the distance, so as to reduce the spread of the
elements. If the mixture until the liquid viscosity is low, can not stir
a long time to reach a random mixture of state; if a higher viscosity,
it would take a longer mixing time. The density of different components,
each of the liquid solution, mixing produced Cut and a strong role in
the turbulent density of the liquid droplets into small pieces and
spread it evenly to the main liquid. Produced by mixing liquid must be
greater than the speed of the flow velocity of the droplets. Not a small
amount of powder dissolved solids and liquids mixed mechanism, and the
density of different components, each of the liquid solution of the
mixed mechanism is the same as the mixing can not change the size of the
solid powder. If the pre-mixed solid particles so that it can not be
less than the velocity of the fluid flow rate, No matter what way can
not be mixed to form a uniform suspension. Paste mixture of different
materials is the main material to be mixed and separated them by
repeated pressure, rolling, extrusion, and other actions arising from
the strong shearing, and then repeated by the merger of the Kneading,
the last to reach the required level of mixing. This mixture is very
difficult to achieve the ideal mixture, mixing only to meet randomly.
Solid powder and liquid mixture to a small amount of paste material, and
its mechanism of mixed paste material mixed with the same mechanism.
Different thermoplastic materials, as well as thermoplastic materials
and a small amount of powder mixed solid, strong need to rely on the
shearing, repeatedly rubbing Kneading and in order to achieve the random
mixing.
Good liquidity granular solids rely mainly on its own container
rotation, or on a container mounted on the role of moving parts,
repeatedly turning, and the admixture can be mixed, such materials can
also have a convection air currents or turbulence in order to achieve
mixed . The solid particles or convective turbulence generated vortex is
not easy, well below the rate of mixed liquid mixture, mixing mixer
generally can only be achieved randomly mixed. The mobility of the poor,
the occurrence of each of the adhesion of solid particles or powder,
are often required with mechanical pressure and turning and rolled over,
and other mixed-action machinery. Late grinding launch has farmers
hustling (
Ribbon mixer)
THIBODAUX — A late
arriving sugar-cane-grinding season started at a slower than usual pace
in Lafourche Parish Monday, farmers and mill operators say, thanks to
the lingering impact of hurricanes Gustav and Ike.
While the parish’s
sugar-cane leaders are optimistic that grinding season will gain speed
in the upcoming days and weeks, they caution additional wet weather or
an early freeze could lead to large financial losses.
Grinding season
was scheduled to start two weeks ago, but the storms forced mills to
give farmers more time to plant additional cane to replace downed crops,
replenish their work force and repair damaged equipment and buildings.
“It will be difficult
for us to make up lost days,” said Jim Simon, general manager of the
Thibodaux-based American Sugar Cane League. Simon added this delay will
not result in higher prices for consumers, but it could hurt farmers
already reeling from increased production costs.
Several weeks of sunny weather have provided Simon and others cause for optimism, he noted.
“If we would have
continued to have rain that would have been disastrous,” Simon said.
“We’ve had a spell of three or four weeks with pretty good drying
conditions that has helped us out.”
Onsite grinding (
Ribbon mixer),
a process designed to extract juices from the sugar-cane stalk, was
scheduled to start today at Lafourche Sugars in Thibodaux, mill General
Manager Greg Nolan said. The process began Monday night at Raceland Raw
Sugars, plant engineer Neville Dolan said.
As trucks loaded with
cane began arriving at Lafourche Sugars Monday afternoon, Nolan
described a litany of storm-related obstacles his company overcame.
“It’s nothing but a
hustle,” Nolan said, as he clutched a soft-drink cup. “We’ve been
fighting all the hurricane problems, labor problems, fixing problems …
like everyone else.”
Lafourche Sugars is
expected to process 940,000 tons of cane this year, Nolan said, noting
that figure is down 10 percent from 2007.
That number could
decline further if wet or cold weather interferes with cane growth.
Regardless of the conditions, Lafourche Sugars’ 80 full-time employees
and 40 part-time employees are facing three busy months.
“We try to wrap up
before Christmas,” Nolan said. “Some years it happens, some years it
doesn’t. This will be one of those years it doesn’t.”
Veteran farmer Godfrey
Knight can cope with a long year. What he hopes to avoid, however, is a
year like 2002, when the rains following Hurricane Lili seemingly never
stopped. Knight only planted 100 of 650 possible acres of cane that year
because of the weather.
So far, Knight, who has planted cane in Thibodaux since 1956, has reason to be upbeat.
“If it stays dry, it won’t be that bad,” Knight said, as he overlooked his field near the Brule-Guillot Road.
By Raymond Legendre Staff Writer Food Mill
A food mill is a piece
of equipment designed to remove the seeds, skins and tough fibers from
raw or cooked fruits and vegetables. It is especially useful when making
butters, smooth sauces, applesauce or seedless jams. Food is placed
into the mill, and the handle is turned to force the food through a
metal disc perforated with small holes. Discs with different-size holes
may be used, depending on the type of food to be milled. the size of the
seeds to be removed and the desired consistency of the finished
product. The seeds and skins are forced to one side, while the pulp
passed through the disc. Using a food mill is faster and easier than
trying to remove the seeds and skins from fruit by forcing it through a
fine sieve. (

The Foley food mill was
the first food mill to be made readily available to the average
consumer, and as a result, is the most commonly known brand. When
purchasing a food mill, make sure that it is made of stainless steel. It
will be sturdier, work better and last longer than the cheaper ones
that are tin-plated or made from plastic. The tin-plated food mills tend
to rust after only a few uses, and the plastic ones break easily.
Sieve
Fine-meshed sieves are
useful for separating the juice from the fruit pulp when making jellies,
syrups and vinegars. A sieve may be used in place of a food mill to
separate the seeds and skins from the fruit pulp when making sauces and
batters or to puree applesauce. Curds and many juices are also strained
through a sieve. The mesh should be very fine to prevent small seeds and
bits of fruit from passing through the sieve.
Metal sieves, other
than those made from stainless steel, tend to rust quickly and can
impart a metallic flavor to the food. Sturdy plastic sieves with a
stainless steel mesh are an excellent choice because they clean up
easily and will last a long time. Use a stiff brush to remove small food
particles that may become trapped in the mesh, then rinse the sieve
under running water until all signs of food and soap are completely
gone.
