The plant is designed for the production of animal feed based on vegetable raw materials (the main component is maize) in an agro-industrial town in Latin America.
Produced feed will be supplied to livestock farms.
The capacity of the plant is 10–12 t/h of bulk feed or 10 t/h of pelleted feed (per die: 4.0 mm).
Technical description of the Compound Animal Feedstuff Plant
- Reception and cleaning
Raw materials either in bags or in bulk is fed into the loading pit. The cleaner separates the grain with a sieve that removes large contaminants, and a sand sieve that removes particles smaller than the raw material itself (if included in the supply). Dust and other light particles are removed by the integrated aspiration system. Magnetic metal impurities are removed when the raw material passes through a permanent magnet.
- Silos for raw materials / dosing
Before dosing cereals and other macrocomponents are stored in bins for raw materials. Supply of raw materials to the bins is carried out by chain conveyors. Raw materials that form a specific recipe are fed individually by discharge augers and sequentially weighed in a weighing bin mounted on strain gauges. This weighing procedure provides high accuracy and uniformity when weighing each batch.
Supply and dosing of raw materials to the crushers is carried out using feed screws. At the entrance, the crushers are equipped with magnets that remove magnetized metallic impurities. Grain / raw materials are ground by hammers with an appropriate degree of grinding, which ensures the ideal structure of the compound feed. The discharge screw unloads the product from the hopper under the crusher.
- Dosing of micro-components (if included)
Dosing of micro-components is used to add small amounts, for example, vitamins, minerals, premixes, etc. Components are stored in bins, from where they are metered and transported to a central weighing facility, suitable for accurate weighing of small quantities.
Accurate mixing is of high importance for feed quality. Dry products are thoroughly mixed in a paddle mixer. To fully utilize the performance of the mixer, the latter is completed with preliminary and unloading bunkers, which are storage tanks.
- Granulation (if included)
The granulation section consists of a series of machines that transform the feed into pellets. The feed is fed into the air conditioning mixer, where steam is then added to raise the temperature and moisture of the feed, which facilitates the granulation process and leads to increased granule strength. After the feed was pushed through the matrix, which can be of different diameters and thicknesses, the hot granules fall directly into the cooler, where they are cooled from about 80 ° C to room temperature. In the production of animal feed, it is sometimes necessary to crush the granules into granules with the help of a binder. At the final stage of the process, the granules are sieved and cleaned to obtain a product that does not contain dust. Additionally they are sprayed with oil / vitamins in the sprayer.
- Finished Product Bins (if included)
Bunkers of finished products serve as cumulative containers before using or shipping compound feed to compound feed carriers.
- Liquid Components System
Frequently it is more profitable to add one or more liquid components to the feed and / or granules. Each of the liquid components is stored in a temperature-controlled container. Before feeding and dosing into the mixer / sprayer the liquid passes through the filter.
The compressor continuously produces dry compressed air for the operation of the entire pneumatics of the plant, for cleaning filters, various sections and general cleaning.
- Management system
The central control panel allows operators to monitor and control the entire process. The control panel includes a computer for programming recipes, production tasks, etc. It also stores information about products, raw materials stocks, etc.
- Aspiration system (if included)
An aspiration system with several single-point filters ensures a low vacuum in the right places on the production line, and thus reduces the risk of dust entering the workroom to a minimum.
