Grinding millThis second crushing system, the raw material grinding fineness of 80 mesh by 95% of the fine powder, fineness of demand for production of small particles of feed is quite important.If only production mold pore size of 2.5 mm and above feed particles, this step is optional.
Two hybrid systemWith premix materials will be fully mixed.Floating production way, here is not recommended to add grease.Suggested to use after extrusion cladding oil machine to supplement the required total fat content.
Before extrusion machine and conditioningRaw materials via feeder stability into the biaxial mixer (DDC).DDC in just the right amount of adding water and steam, residence time within the DDC by spindle speed control.Proper big provides two types of technology: single shaft extrusion machine and reverse twin screw extrusion machine.
The dryerDryer will squeeze out the grain moisture content by the dryer entrance of 20-28% reduced to below 10%.Reduced water activity in grain, the product shelf life can be extended.
Covering the oil machine

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.

The cooling machine

Cooling machine by using ambient air to reduce the temperature of hot particles + 3 ° C to room temperature.

Vibrating screen

All particles in front of the bag by shaking sieve to remove any irregular granular or powder materials.

Automatic bag filling and sewing bag system

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.

24/7 of the robust design

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.

formula

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.

hybrid

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.

Two sections of crushing

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.

Early hydration,

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.

Before tempering

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.

Before reverse twin screw extrusion machine and conditioning system

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.

The dryer

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.

cooling

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.

Covering the oil machine

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.
