On this drawing you can easily see all essential parts of the TEWE AIRFEED II feeding system. The construction of this system is absolutely compact and extensively self-explanatory. In the room next to the house you can see the mixing station, here actually type pa ral-lel mixing container. With this type you can do parallel mixing and dosing. The infeed of this mixing station will be

done by worm convey-ing systems. Built on the top of the mixer you can see additional additive

dosing devices. As neces-sary these devices can be manually fed in and dosed out automatically.

Next to the mixing station is the water tank with water pump apart to guar-antee an evenly water pressure. The water pipe will be installed along with the stainless steel feed pipe to the feeding places. The particular feeding places will not be supplied from a central point but from by means of the shortest way out of the feed pipe. In case of needing liquid feeding places the water will be dosed in just above the trough at the end of the feed pipe. That has the advantage of highest cleanliness and hygiene at the feed pipe outlet.

In the drawing are shown different feed-ing places which are adapted to the needs of the particular feeding groups.

Trough made of stainless steel for young sows or fatteners

Short trough made of stainless steel for sensor feeding of piglets or fatten-ers

Oval trough made of stainless steel, especially for piglets, with super-structure, assembly freely in the pen. Also available with sensor for sensor feeding.

Of course all kind of automatic feed-ers can be fed with dry feed. The infeed will be done almost dust-free because of the stream-optimized cyclone.

Instead to an automatic feeder you can feed in to a feeding trolley, small silos for further compartments with own dry feed systems, sows in farrowing pens, service center or gestation house.

Consequently this system is most flex-ibly applicable for all possible situations in pig keeping.

Airfeed II

The parallel mixing station is consisting of a weighted mixer and a weighted buffer container. The parts contacting the feed are completely made of stainless steel (1.4301) except the mixing screw which is made of wearresistant steel. The station is ready mounted in a very stable coated framework made of square profiles. Freestanding setup everywhere possible. The devices mounted in the framework are easily accessible for service works.• Mixing and dosing is going on simultaneously. Parallel to the mixing procedure the

dosing is going on so a dosing output up to 1,000 KG/h is possible. • Funnel-formed vertical mixer with double bearing and effective mixer with capacity of up

to 30 KG per mixing process. The weighing system is working with 10 Gram resolution for highest definition of the mixture formulations.

• The vertical mixer is fitted with an electro-pneumatically working double-flap for quick emptying of the mixer. Dustfree forwarding to buffer container.

• For quick and safe emptying to the rotary feeder the weighted buffer container is fitted with a motorpowered discharging device. Advantage: restless emptying, that means highest hygiene level and separation of the mixtures.

• Mixing motor 0.75 KW 380/400 V in highly effective and power-saving version with spur gear. Coupling disk with starter cushioning.

• Motor discharging device with merely 40 Watt at 380/400 V. Discharging device with gear sparing drive by chain. Chain completely enclosed – accidentproof, durable.

Compared to so far ‘’open’’ rotary feeders TEWE Elektronic made a new energy-effi-cient development with an enduring hermetically sealed rotary feeder without airstream through sewer port. Further advantages are:• Sluice consists of lamella wheels each with 8 chambers strung on an axle.• Lamella wheels made of special plastics, flexible and high-strength in construction,

thus lowwear and resistant against foreign material.• Simple maintenance and cost-efficient spare parts since also single lamella wheels

can be substituted.• The 8 chambers of the lamella wheels ensure a continuous feed dosing into the air

stream.• Low energy consumption rate.• Drive motor hermetically sealed and economical: only 40 W power input.

The pipe diverter developed by TEWE Elektronic is completely made of stainless steel (1.4301) and is operated electropneumatically. This innovative new development is characterized by some special details:• Corresponding to the principal of fluid dynamics the pipe diverter has a fluid optimized

branch angle (= outlet angle from valve to feeding place). This is the reason for a) an im proved flowability especially of feed mixtures containing CCM, b) a better hygiene, c) less wear of the diverter itself and finally less energy consumption.

• The pipe diverter can be used as branch (distribution behind the rotary feeder to transmission lines 2, 3, 4 etc.) as well as discharge valve. The pipe diverter can be assembled under every spatial condition. Simplest mounting by single pipe system.

• It is only one moveable flap (made of stainless steel) in the valve, with Teflon coating on inner surface. Flap with exterior arresting bolt, therefore simplest servicing. Absolutely stable construction of all mechanical components guarantees long economic lifetime of the device.

• The switching mechanism of the feed pipe (open/close) is reacting in matter of seconds and guarantees a very fast discharging from feeding place to feeding place what effects a highly effective discharging output of this feeding system.

• Because of the mirror image-like construction of the pipe diverter the opening mechanism can be installed on the left or on the right side of the diverter.

• Due to the exceedingly small construction of the pipe diverter it is possible to do assembly directly on a wall of a barn.

Automatic Feeder and Trough Systems

Pipe diverter

For various purposes it is possible to do infeed to different feeding places with the AIRFEED II feeding system.• Every kind of automatic feeder for dry or mash feed: In these cases infeed will be done via• a new developed cyclone. This cyclone has a fluid-optimized shape which causes an espe

cially efficient separation of air and feed, and will result in an almost dust-free infeed to the automatic feeders.

• TEWE oval trough made of stainless steel, especially for piglet groups of 25 to 30 piglets, from 6 to 30 KG: Especially suited for liquid feed mixtures for piglets. Compared to the wellknown round troughs the oval trough with bigger circumference (=more feeding places!) provides also a fast and even mixing and distribution of the pouring in liquid feeding.

• Short and long troughs, made of stainless steel, for piglets and fatteners, optionally with superstructure for free standing in the pen, or without superstructure for assembly in the partition wall. Length and height of the troughs according requirement, depending on quantity and age of the pig group.

• All these trough systems have the same advantages: Highest hygiene level because of simple cleaning and disinfection of the complete trough. Highest hygiene level also at trough outlet pipe as mixing of feed and water (arbitrary water/feedration) is done at pipe outlet directly above the trough.

• it takes the shortest way directly to the feeding place• no hindrances/deviations/bottle necks on the way to the feeding place• feed portions will be transported to the feeding place within seconds• no loss of time or waiting times caused by long valve response times or positioning of distribution

devices

• ideal for enlarged farms with nooks – also for multi-story houses• feed pipe distances up to 200 meters are possible depending on the number of valves and pipe

elbows• easy to assemble in existing farm houses and to adapt to existing troughs and automatic feeders • controlling: by TEWESTAR computer – introduced at best and successful in many cases in the field

of liquid and dry feeding systems

• only dry feed from mixer directly to the feeding place• preparation of the mash done directly above the feeding place• feed pipes without feed residues because of barrier-free conveyor line from rotary feeder to the feed-

ing place• feed pipe with quick opening device above the mixing head for checking purpose• Exclusive and highly effective rinsing programs with fresh water directly above the mixing head• trough hygiene level very high: because of dosing in small portions the trough is always clean

• daily growth rate up to 20 % higher• reduced power consumption because of barrier-free conveyor line from rotary feeder to the feeding

place• no electronic components in the animal house: no corrosion => long life • no loss of weight caused by feed diversifications: high compatibility by means of up to 30 feeding

times daily – small portions, feed always fresh• discharging of feed with high ratio of dry mass/energy possible without problems if necessary• also single feeding places with specific mixtures and energy values• multiphase feeding with infinitely variable phase blends• adjustment of animal weight-dependent mixtures for single troughs or single valve groups• feeding as required by sensor or restrictive feeding according feed curve only

Diagram „block fee d ing after status empty‘‘: The animals will be fed within an ad justable time after sensor gives message that the trough is empty. For this pur pose the trough scan ning will be started parallel to the first feeding process and is then permanently monitoring the trough status (full/empty). As soon as a minimum mixing amount is reached (as measured by empty troughs) the corresponding empty troughs will be filled again. This procedure will be repeated within the range of programmed times and maximum feed amounts.

Diagram of bio phase feeding for automatic, infinitely variable and agebased adjustment of the mixtures.

On the screen surface of the TEWESTAR 5 giga visualized illustration of an AIRFEED II system design: Parallel mixing station, infeed from silo, CCM storage dosing device, additional component dosing device. Discharge to several transmission lines to different feeding places. This visualization can be compiled from customer according to the specific data for “his” house system.

The AIRFEED II single mixing station consists of the weighted mixer with 180 liters content and the rotary feed er which is directly flanged beneath the mixer. Here also all feedcontacting parts are completely made of stainless steel (1.4301) except the mixing screw. Stable framework, made of square profiles, powdercoated. Operation se quence: First mixing, then discharge. Example: If a const ant mixture is needed for sows in farrowing pens it is pos sible – within the range of 180 liters content – to do at the same time mixing for these valves and then discharge one valve after another. Of course the discharging ca pac ity of the rotary feeder is the same as the one of the parallel mixing station, but in the single mixing station the just mixed feed amount has to be dosed out first before a new feed amount with same or different recipe can be mixed again. Hence the feed amount what can be definite ly discharged to the animals within a certain time ‘‘x‘‘ is about 30 % less compared to the discharging amount of the parallel mixing station.
