next preparation.



Tank cleaner
The tank cleaner allows thorough, fully automatic cleaning
of mixing and rinse water tanks. This is achieved by app-
lying rotating cleaning heads with specially-designed varia-
ble nozzles. These nozzles can be adapted to the respec-
tive water pressure as well as the quantity of water
required. Consequently a very small quantity of water
can still achieve optimum cleaning throughout the enti-
re tank.
A separate water pipe – preferably with a separate fresh
water pump – supplies the cleaning heads with water.
This tank cleaning system can also be attached to any
existing liquid feeding system. To ensure trouble-free
operation, the tank has to be completely water-tight and
it must be possible to close the component intake opening
with a pneumatic flap.


Acid fogger
The acid fogger is ideally suited for disinfecting mixing and rinse
water tanks. Several times a day, this system distributes very small
quantities of disinfection solution in the tank. This allows the dirt film
to be removed without residues occurring on the inside of the tank
after long operational use even with the tank cleaning system being
applied. The fog penetrates every corner of the mixing tank, so ensuring
optimum disinfection and hygiene.
The acid fogger starts rotating by compressed air at 8 bar. At the
same time, negative pressure is used to suck the acid/lye directly
from the can (possible distance: 2.5 m) without the need for a pump.
The system can be controlled separately or by means of a suitable
feeding computer.

also highly benefits from the effects of fermentation by:          (see test results).



                                                      Fermentation process
                                                      Fermentation is the process of breaking down carbohydrates
                                                      by means of micro-organisms in the absence of air. These
                                                      micro-organisms produce enzymes, which in return transform
                                                      the starch contained in the grain into glucose. Glucose is then
                                                      converted into 2 Lactate (a salt of lactic acid). The feed is thus
                                                      preserved naturally – a process comparable to the making
                                                      of silage. It goes without saying that such a process has to
                                                      be controlled and monitored. For instance – it is necessary
                                                      to permanently check the pH-value and the temperature.


                                                      Advantages of fermented feed
                                                      Fermentation is a kind of predigestion process and thus
                                                      greatly increases the digestibility of the feed.
                                                      Consequently the pigs need less energy to digest it.
                                                      The nutrient absorption is much improved, which in
                                                      return results in a better feed utilization. Moreover, the
                                                      low pH-value considerably reduces the content of
                                                      harmful bacteria within the feed.



                                                      Advantages for the pig
                                                      Thanks to the quicker pH reduction within the pig’s
                                                      stomach, less pathogens can settle there. Lactic acid
                                                      bacteria greatly improve the intestinal flora in the pig’s
                                                      small intestine, thus stabilising the animal’s health
                                                      status. Moreover, the increased concentration of lactic
                                                      acid bacteria results in an improved energy utilization.
                                                      In this way, less indigestible feed gets into the large
                                                      intestine, so that the pigs suffer less from diarrhea.

Silohaake-MEDIsystem – the ideal medicating and soaking system
The MEDIsystem offered by Big Dutchman enables
you to supply your animals with exactly calculated
dosages of medicine, vitamins or other agents – and
all this accurately and fully automated!
Medicine is metered out directly into the drop pipe via
individual feed valves, thus guaranteeing that the
active substances do not get into the feed pipe.
In case of feed stub pipes, accurate dosage is also
achieved by means of injectors dispensing the medicine
directly into each feed stub pipe => a cost-efficient solution.
By means of automatic pressure control, the dosing capacity
of the MEDIsystem is adapted to pressure fluctuations
in the feed pipes => increased dosing accuracy.
Since the pumping process continuously mixes the
additives, even barely water-soluble compounds – which
are often much cheaper – can be used without problems.
Following medication, it is possible, if required, auto-
matically to empty the MEDI pipeline circuit by using
compressed air and then to clean it with water.

Mixing tank with agitator
You can choose:

   steel (V2A) in sizes of 500 to 12,000 litres useful
   content (larger tanks upon request);
2. round or rectangular tanks made of acid-resistant

Electronic weighing system
According to their construction, mixing tanks are
equipped with an electronic 1-, 3- or 4-point weighing
system. Weigh bars are mounted below the feet of
the mixing tank. They record the change in weight
during metering in of feed components as well as
during the dispensation of the ready-mixed feed and
transmit the corresponding data to the MC 99 NT
feeding computer. The computer can be set to cali-
brate whether the weigh bars are supposed to be
working with a resolution of 1 kg or 100 g – this is
valid up to 6 t total weight!

Feed pump
Depending on the feeding method, the pipeline
length and the kind of feed used, either centrifugal
pumps or positive displacement pumps (also
frequency-controlled) with different capacities are
used.




Centrifugal pump                                         Positive displacement pump
Intelligent feed valve and pipelines
Feed is pumped from the mixing tank through acid-proof plastic pipes
(Ø 50 or 63 mm) to the feed valves.
This innovative and “intelligent” feed valve is based on the pioneer
BUS system, thus allowing fast, secure and flexible data-transfer. This
is made possible thanks to a minute, individually programmable
plug-in card fixed to the valve. The valve can be installed rapidly, so
that the electrical installation costs can be reduced by 50 %, since
only a simple two-wire line is used. Another asset is that the sensor
technology is already integrated in the “intelligent” valve, allowing
simple sensors without sensor electronic to be used.
The valve itself is a highly reliable and long-life pneumatically-operated
diaphragm valve, which guarantees a high degree of metering precision
and offers versatile installation possibilities.

HYDROMIX-Synchron – rapid feeding of large animal numbers

 Operating principle                                                                       1

 HYDROMIX-Synchron allows mixing and feeding at the
 same time with only one computer. To do this, the re-
 spective feed components are mixed in the mixing tank,
 passed into the feeding tank and, from there, pumped to
 the individual feed valves. The computer at once starts
                                                                                       2                    3
 the next feed formula so that mixing can start anew.
 Large numbers of animals can thus be fed with many
 different rations, but without too long waiting times.

Multi-phase feeding – nutrient supply to animals depending on their requirements
If more than one feed formula is used during the finish-       called multi-phase feeding. It provides any number of
ing period, this is called phase feeding. If a different       animals with the exact nutrients each one needs per
feed formula is distributed every day, however, this is        day.


  Operation principle
  The components necessary for a multi-phase
  feeding system are: at least 2 (max. 4) mixing
  tanks for the respective basic mixes, 2 feed
  pumps with frequency converter, 2 feed pipes
  and 2 feed valves per trough.
  When feeding starts, the computer evaluates the
  required quantities of the different basic mixes
  for preparing the individual daily delivery for
  each valve. MC 99 NT controls the performance            1           2           3           4
  of the feed pump and the valve opening time
  per valve. Both valves at one trough have the
  same opening time. A frequency converter
  ensures that small feed quantities are then
  metered out for as long as large quantities.
  This system allows the feed to be supplied
  according to the animals’ requirements every
  day.

Sensor feeding – optimum use of feed intake capacity
For more than 15 years, some Big Dutchman customers
have fed their pigs with a HYDROMIX-Sensor feeding
system. This type of system has become increasingly
important in the past, since it allows short troughs to
be used and a ratio of animal to feeding places of up
to 5 : 1. This results in a better use of floor space and
the introduction of large group pens.
The principle is as follows: a sensor is installed 2 to
3 cm above the bottom of the trough so that the
MC 99 NT feeding computer can check at regular inter-
vals whether the trough is empty. Whenever required,
fresh feed can be dispensed. This increases the incen-
tive to eat. The animals determine their own daily rou-
tine by their feed consumption behaviour => signifi-
cantly better use of genetic feed consumption capaci-
ty.
