The use of extruded feed:
-provides digestion and stimulates the digestive tract of young animals
-improves the safety of young fish livestock up to 95%
-reduces feed consumption by ~ 20%
-increase the feed digestibility up to 90-95%
-increases feed shelf life up to 6 months enables usage of substandard grain
-improves the energy value of combi-feeds
The line consists of:
1 - Grain pneumatic conveyor (optional);
2 - hopper for fine ingredients (1 m3) – 3 units;
3 – hopper for corn ingredients (8 m3 - 6 tons of grain) – 3 units;
4 – hopper for bulk additives;
5 – tunk for liquid additives - (optional);
6 - mixer with a screw conveyor;
7 - feed extruder;
8 - conveyor (optional);
9 - crusher;
10 – granulator
11 - air conveyor (optional);
12 - storage bin (5 m3);
13 - screw conveyor (6 pcs.);
14 - packaging apparatus for filling bags from 5 to 50 kg;
17 - remote-automated line control unit.
Completion of the line can be changed according to the buyers requirement (number of hoppers for raw materials can be changed depending on the number of its components).
Brief description of extruded combi-feed production.
The initial grain components is loaded from car or another vehicle into the storage hopper (3) using a mobile air conveyor (1) (option) (pneumatic loader) or manually. Pneumatic loader (optional) is a mobile unit with a fast-mounted pipelines. According to the given feed receipt, the grain forage is fed into the mixer (6) mounted on the weight sensors, fixing and controlling the incoming dose of ingredient, using bins screw conveyor (option) or manually.
The additional hoppers (2) for ingredients necessary for production feed for fish (cattle meat flour, fish flour, fodder yeast) are also provided. The system for adding fodder supplements is also foreseen. For this, the additives are fed into the mixer by strictly set quantity the hopper for dry additives (4) via the screw conveyor. In this case the tank for fluidized additives (5) can be used. The synchronized adding of these additives is foreseen. The additive dose is strictly bulked by the mixer. It is possible to set an option on the remote control unit, which excludes the start of mixing ingredients until the set weight of component is set, what eliminates non-complience with technological receipt.
When all ingredients achieved set weight parameters in mixer (according to formulation, given to the control unit), it starts mixing process.
The mixer tank capacity makes 210 дм3 . The weight of one batch is adjusted from 50 to 120 kg. The mixing time is 5 - 10 minutes. At line productivity of 150 kg / h, the optimum batch weight is 50 and 75 kg, which is respectively 3, and 2 cycles per an hour.
After completion of the mixing process, the raw material enters to the hopper of an extruder (7) via a screw conveyor (optional) or manually. Upon completion of unloading, the mixer starts a new cycle of loading and mixing. Meanwhile, the product is dispensed from the hopper into the extruder.
The extruder operates continuously, as it is happening timely additional loading of raw materials from the mixer into a hopper of the extruder by filling control device that eliminates the utter devastation of the hopper during operation of the extruder. Also, this controller stops the loading in case of filling hopper level. The mixer performance exceeds the performance of the extruder, which also contributes to the continuous operation of line.
During extrusion of grains it is considered a short-time temperature and pressure impact resulting in the converting of structure and properties of nutrients. We can receive a structured feed having high taste and nutritional properties. During the short period of time all compounds are simultaneously mixed, pressed, grinded, heated, boiled, sterilized and formed. A sharp pressure drop during the product exists from extruder trunk, which leads to the deep conversions: the walls of cells and chemical compounds brake, raw material structure changes,microflora (bacteria, fungi) is destroyed. Extrusion treatment increases the product digestibility due to its conversion into easily digested form of the raw material components both animal and plant origin and complete disinfection of food.
The extruded product is fed to a crushing mill (9) through the conveyor (8) (optional) or manually. The crushed extruded product is loaded into the storage hopper (12) by pneumatic conveyor (11) (option) or manually.Incaseofproductionthefeed for fish the product after deeding moves to the granulator (10) for granulation. Grinded extruded product is loaded into the storage bin (12) via the air conveyor (11).
The final stage of the production line is the packaging of the product (optional). From the storage hopper the product via the screw conveyor (13) (optional) or manually enters into the semi-automatic filling unit (14) (optional), equipped with a batcher, conveyor and package sewing machine. The weight of dose is adjusted, the maximum weight - 25 kg.
