Plant for the production of dried fodder

Field of application of the invention

The invention includes a plant for the production of dried fodder intended for the economic preparation and processing of fibrous materials, weighing straw, with the aim of increasing the concentration of energy in the fodder and delivering it in compacted or loose form.

The plant is preferably used for the production of straw concentrate mixtures, where it can be performed as Kompaktieranlage, as part of a drying plant or a feed mill. Due to their compactness and their variability - Baukastenprinzip- the system can be arranged in flat and floor buildings and also designed as a rack system.

Characteristic of the known technical solutions

There are facilities for processing dry food, preferably straw to feeds with increased energy concentration known where the increased energy concentration is achieved by digestion agents, such as UaOH, NHo and others.

These plants are constructed in such a way that bale straw (big bales, high-pressure bales and normal bales) can be processed in an orderly way.

The bales are shredded with chaffing units, fed to a machine to reduce the Gutsschwankungen and then conveyed via screw conveyors in a mill that works on the principle of impact crushing. From the mill, the milled material passes pneumatically via separators and filters into a lye mixer. The mixed with lye straw comes into the molasses mixer, which passes the material into the press after the mixing process. From the press, the compacts (pellets) are conveyed mechanically into the BaneLkühler and after completion of the cooling process in turn takes place a mechanical discharge of the pellets from the belt cooler ·. , ... "...

Other systems are known in which the conveying to the mill also takes place mechanically and a cooling tower is used instead of the belt cooler.

Also known straw pelleting plants with a container station, which is used for storage, processing and dosing of solid components ·

Characteristic of the known systems is that they are composed of individual machines and equipment parts, each machine usually performs only one step. Lately, there are straw grinders -Taarup-, which crush straw and at the same time interfere with NaOH. · In a closed plant there are no such machines. The known systems have the following disadvantages:

- high machine and plant engineering effort,

- high specific material costs,

- high specific energy consumption,

- large volume of construction, ... · ......

- high electro-technical effort- and.

- Unacceptable large dust nuisance of the operating personnel through open conveyor.

Object of the invention

The invention has the aim to eliminate the disadvantages listed. This is achieved by equipping the plants producing straw-concentrate mixtures and other products with machines that perform several process steps at the same time. This creates a compact design that allows good monitoring and process design.

Presentation .-- of the essence of the invention

The object of the invention is to provide simple plants for refining feeds with a low concentration of energy in a loose or compact form, where several processes can be carried out, ultimately all process steps in one machine, the plants being mobile or stationary are to build up.

The object is achieved in that in one, plant or machine, the process sections

- processing (comminution and digestion) of low-energy feed materials, mainly straw;

Mixing and buffering the processed feedstuffs with solid and liquid components;

- pressing the mixture and

- cooling the compacts

will be realized. ,

File become the fibrous substances with their properties to control the solid, liquid and gaseous components

used · '....

The system is modular in design and can therefore be expanded or reduced as desired and thus used in a very versatile manner in agriculture.

Ausführungsbei game1

The invention will be explained in more detail in the following embodiment.

The accompanying drawing shows in

Figure 1 - the structure of a plant · for dry feed pelleting

The plant for the production of dried fodder consists of an acceptance feeder 1, which contains a dissolving and dosing or sorting machine 2 for straw bales. In this machine unit, the process steps-storage, conveying, dissolving and arranging and dosing-are carried out. Furthermore, in this machine bale straw can be processed disorderly, chaff and long straw. The machine is followed by an angled conveyor belt 3, which transports the fibrous substances to the foreign body separator 4, the foreign body separation taking place by utilizing the different specific weight. The 'conveyor 5 transports the fibrous materials to the Zwangεzuführung 7 »while it can be placed on the conveyor 5 and straw bales (except large bales). The conveyor 5 includes the metal locating device 6. The feeder 7j, consisting of two conveyors or a conveyor and superimposed conveyor rollers, realizes the conveyance and clamping of the material to ensure a continuous supply to the stalk remover 8 in which the disintegrating agents during or after comminution added and mixed. This machine construction with the machines 5 to 8 makes it possible to store, process and meter the fibrous materials, so that an entire process section is carried out in a simple machine. The machines 1 to 4 are additional equipment and reduce the living labor within the plant.

This is followed by the steep conveyor 10 to feed the gravity paddle mixer 11, in which all components are mixed according to specific recipes As a result, the compacting machine 12 can be charged with a constant volumetric flow and constantly operate at its upper power limit Furthermore, the gravity paddle mixer 11 compensates for dosing fluctuations, thereby increasing the quality of the dry food now via the conveyor 13 in the compacting machine 12 or on the conveyor 14, which transfers the loose mixture to a transport vehicle After leaving the Kompaktiermaschine 12 the pressed material with the vertical conveyor 15 to the Kühlmas handed over to chine 16. If the cooling process is completed, the screening of the abrasion by the screening machine 17 · The abrasion is returned via the conveyor 18 on the storage, preparation and metering stat ion 20, ube "r the conveyor 21 and the conveyor 24 on the steep conveyor 10»

The cooled pressed material is transferred to the vertical conveyor 19 on a vehicle.

The storage, processing and dosing 20 consists of storage containers, dosing, a mill 23 and mechanical conveyors. The material passes through the conveyor 21, the mill and the conveyor 24 on the steep conveyor 10 or via the conveyor 22 and 24 on the steep conveyor 10. The processed solid components are from the storage, Aufbereitungsund dosing 20 via the vertical conveyor 25 the gravity paddle 11th fed directly.

The preparation of the solid components can also be done outside the plant. The machinery and equipment for storing, processing and dosing the liquid and gaseous components 26 and 27 can be used both in the plant for

Dry feed production can also be used in other treatment plants.

The urea dissolving machines and equipment 28 are used to store small amounts of molasses, in which the dissolution of the urea takes place.

The entire plant for dry food production is from the Halmgutauf.bereiter 8 to the cooling machine 16 as closed. This system enables a negative pressure to be generated by the aspiration system 29 to 32 in this system, which substantially reduces the dust nuisance for the staff.

The control room J \ - is a closed room, from which the whole production process including the straw acceptance is supervised.
