In addition to the chicken feed, duck feed and is also a main type of poultry feed.Ducks feed formula containing a high proportion of fibres, making powder very fluffy.According to the experience, the use of a large number of direct steam treatment with high fiber content of feed formula are relatively difficult.Too much direct steam will eventually cracks in the surface of the pellets.Fiber content is proportional to the particle quality.However, high fiber content formula can reduce granulation forming capacity.Can be added in the mixing machine, therefore, about 1% of the water to fibre softening, which can improve the production efficiency, increase production capacity.
The raw material
And animal feed is composed of coarse particle and powder materials
Before crushing
Optional steps to dealing with coarse particle materials.
Before the crash will reduce the energy consumption of fine crushing required.
Temporary barrels
Temporary bucket will be on the same day the raw material for production.
Before entering the feed production process, some raw material from the silos will be first to enter the temporary barrels.
Batching and weighing
Raw material will be according to the recipe ingredients.
After crushing
After crushing is raw materials reduce the sizes in the shrimp feed production line process
This process is fine crusher is usually used.
hybrid
In this step will be added and mixed vitamins and minerals and other trace elements.
powder
pelletizer
Granulating conditioning start once upon a time, to steam hydration, further and before into the granulating chamber to form particles help cooking materials.
The cooling machine
Use room temperature air to cool the hot particles out of the granulator.
Need a thorough cooling to prevent condensate the packaging.
Granulating of feed products
Solutions of the crusher
In livestock feed, broken granulating can be finished particle size reduced to smaller particles.This is for easier to feed the infant livestock.
packaging
Packaging for the particles to provide protection, also facilitate handling and transportation to the clients
Livestock feed granulation manufacturing instructions
Countercurrent cooling machine is used for cooling high temperature particles.Temperature (hot) particles into the cooling machine, the exhaust fan to cool indoor hot air discharge, ambient air from the bottom of the cooler into the cooling chamber to cool the particles.When the particle accumulation in the cooling chamber and exposed to high instrument, pneumatic valve will immediately action and feed particles emitted.The countercurrent air design causes the particles to ensure and improve the cooling efficiency of heat exchange.
Particles through conveyor belt into the vibration sieve, using vibration way to remove impurities and deformation of particles.Dust particles and deformation are recycled into the granulating machine side of the bunker.Different sizes of screen mesh will feed particle classification stored in a separate product.
Product particles after weighing in bag, bag sewing machine available packaged or use other transport containers (e.g., bulk vehicle, space package), to the distributor or customer.
Appropriate to relieve crusher series specially designed for improve crushing grain yield.Each solution at the top of the mill have been equipped with rotary feeder, used to control capacity and stable feeding.Two solutions of broken wheel spacing can be easily adjusted, to control the size of the feed section after crushing.
Appropriate process design and equipment features and advantages
To meet customer demand design concept is appropriate big goal all along, we realize the customer in the face of the raw material prices, under the pressure of rising costs and labor costs, energy consumption is still the pursuit of quality products which conform to the market competition, the appropriate design concept is to continuously improve, improve the process and equipment, let the customer get the best profits, we through the following description, show us how to reach the goal of customer satisfaction.
Poultry feed contains a lot of grains, fiber content is higher.Good before tempering machine is the key to the successful production of poultry feed particles.Enough can direct and indirect steam and water softening high elastic fibrous materials.Cooked starch is to form a perfect adhesive particles.
Formula to add too much fat can produce a large amount of fine powder in the process of granulation.Suggested that 1% of fat is added in the mixer, this will reduce the die wear and improve the production of pelletizer.Recommendations will be extra fat outside demand are attached to the particles uniformly spraying way, in order to improve the quality of particle on the surface of the fat content and particle.
