In order to provide the farmed fish nutrition balanced and stable quality of feed, many manufacturers have turned to produce particles fish.According to the behavior of the farmed fish in the water, fish feed can be divided into the flotation feed, slow setting type feed and the feed.Should you provide greatly expanding machine and granulating machine to produce high quality of fish feed.According to the type of fish feed, retrogradation can feed on granulating and puffing system production.pelletizerCan only produce heavy feed, for example, because of quenched and tempered before and after conditioning technology progress, milkfish use granulating production line production of feed is still very common.And extrusion machine can produce heavy, slow down and the buoyancy more types of feed.
The raw material
Size of raw material is composed of coarse particle and powder
Before crushing
This is an optional step, can the coarse particle material first first crush.
Before crushing will decrease the energy consumption of superfine grinding when needed.
Temporary barrels
In general, fish feed line will use 12 barrels.
Each bucket will be filled with about 8 ~ 10 tons of raw materials.
Ingredients and weighing
According to the formula to computer automatic batching material.
In fish feed production line, usually by batch operation.
After crushing
After crushing the fineness of raw material crushing to the demand.
Usually use superfine mill producing ultrafine powder.
Dry mix
This step will add high price raw material, the premixed and vitamins and minerals and other trace elements.
Bulking machine
Conditioning equipment before use, mixing raw materials, water and steam heating.
Raw material inside the casing through high pressure, high temperature, shear, then through molding at the exit.
The dryer
The dryer is the necessary link in puffing process, puffed out after wet particles into the drying machine, finally to dry grain.
Both horizontal and vertical dryer, good moisture control is to choose the basis of the dryer is the most important.
Covering the oil machine (optional)
According to the formula needs, usually oil or enzymes coated particles to increase grain nutritional value.
According to the liquid content, you can use the cylinder cover oil or vacuum (batch) oil machine.
The cooling machine
The temperature of the cooling process is the use of ambient air to cool down after drying temperature is still high hot particles.Need a thorough cooling to prevent finished barrels or bags in condensed water.
packaging
The appropriate packaging can protect the feed particles, easy handling and transportation to the customer
Puffing aquatic feed manufacturing process
Of oil flow can increase the feed nutritional value and palatability.According to the formula you need to add fat, can choose by oil drum machine or vacuum oil machine.
Cooling machine by using ambient air to reduce the temperature of hot particles + 3 ° C to room temperature.
All particles in front of the bag by shaking sieve to remove any irregular granular or powder materials.
Automatic packing scale feed particles can be according to the specified weight after weighing, for example: 20 kg, 25 kg bag filling and sealing storage bag sewing machine.Finished but can be by truck or container bags loaded.
Appropriate process design and equipment characteristics 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.
All the equipment can design is based on the concept of continuous production, and make the refueling leisure time to minimize downtime, appropriate big mission, is to make the equipment after the installation, in addition to routine maintenance and consumables replacement need downtime, all of the devices can be production all year round.
The influencing factors of formula has two aspects: breeding performance and mechanical efficiency.For example, choosing the right source of starch (species) of flour is crucial.Is not appropriate source of starch can reduce vapor infiltration degree and cause the clogging in bulking machine.
Fat and moisture content on the production of hammer mill and superfine mill play an integral role.High fiber content of the formula not only can increase the risk of particle breakage, will reduce the stability of the particles in the water.In the manufacturing process of high fiber content also increases the risk of all mechanical wear and tear.Reduce the hammer, screen mesh and wire mesh model, etc. The service life of parts.
We provide a series mixing machine, depending on customer needs and preferences.Our mixer adopt very strong design, we will continue to develop new features, such as double shaft mixer on the gear shaft drive, can reduce the noise, energy costs and maintenance costs.
We firmly believe that will decrease particles evenly for the benefits of ultrafine powder;The basic goal is processed powder can be accessed by more than 95% 60 mesh screen.Without the superfine grinding process, it is impossible to efficient production size of 2.0 mm and smaller size products;And in the process of large size products, superfine grinding will improve the production efficiency and quality of the final product.This will be for the use of cheaper starch raw materials provide feasibility.
Appropriate production understand many practitioners may worry that using superfine mill of extra energy costs, that is why we have designed this revolutionary superfine mill, its running cost is much lower energy;In addition, can use cost cheaper raw material substitution ability, how much additional energy demand balance superfine mill.Ability to use cheaper raw material replacement costs make up a small amount of extra energy requirements of the mill.Superfine materials could produce more smooth, more luster, the water stability of products.
We are always suggested that in the process of pretreatment in hydration.Dry ingredients in the production stage of hydration can improve yield, reduce energy cost and high quality.In order to estimate hydrate mixture evenly feed grain extruder, we provide the vapor and liquid adding system for DDC, used in liquid mixing.Double blade will help on the axis of rotation, steam and adding the liquid mixing dry materials.
In the tempering process, should be designed by big differential tempering machine, its two axes are driven by two independent motors, so it can effectively improve the energy consumption and reduce noise, when stop, more can be instead of the shaft, by stripping effect.In differential conditioning into the right amount of steam, can promote the quality, and the curing performance, insulation sandwich in the subsequent rapid mixer, can ensure that raw materials before entering the granulation process, maintain full uniform.
Reverse twin screw extrusion machine is the guarantee to improve production quality standards, to reduce the energy cost and wear cost solution.Our extrusion machine is suitable for high fiber formula processing;In general, our machines were able to 25 KWH/ton or less specific mechanical energy in the production of high quality aquatic feed.In addition, these internal feed forward movement of the machine with incredible speed, enable us to run high in fiber and small diameter of the product.
Appropriate big provide T series vertical rotary dryer and CDX series horizontal dryers.
When you choose appropriate the dryer for production, moisture control is one of the key selection criteria;Amount of water on the quality of your production, the production cost and profit are directly affected.A plane is uniformity of moisture control, timely and consistent drying results will determine the target average moisture content.The closer the average moisture content to allow the highest water content, will reduce the raw material weight loss caused by excessive and dry, so as to create more profits for your company.
Countercurrent cooling machine is used for cooling particles.Temperature (hot) particles into the cooling chamber, suction fan will indoor air out of the surrounding air from the bottom of the fresh into the cooling chamber, promote grain cooling effect.When the particle accumulation and when exposed to high sensor, pneumatic discharge valve will immediately action to release pellets.Countercurrent air heat exchange to ensure high cooling efficiency.
In food and feed production, the use of a variety of components with different characteristics.Should provide a highly efficient mixer, according to the formula for mixing the powder and liquid materials.In a lot of food and feed production, may add additional liquid in order to improve the nutritional value and palatability of feed.Should be a mixture of large and covering oil equipment to ensure the uniformity of oil.
