Feed Machine

Leading fish floating feed machine technology

The current fish floating feed machine products have become more and more advanced with the advancement of science and technology. Now the new type of twin-screw floating fish feed extruder machine has developed relatively late in China. After such mechanical materials are sent to the conditioner by the conveying equipment, the materials are conditioned and tempered.

After being quenched and tempered by high-temperature steam in the fish floating feed machine device, it enters the puffing mechanism from the discharge trough, and is instantly extruded and cut into granules from a certain shape of the die hole under the pumping of a pair of mutually parallel and meshing screws.

Due to the wide range of extruded raw material characteristics, the screw speed needs to be adjusted within a large range. Its working principle is much more complicated than that of a single-screw fish floating feed machine, and there are large differences in specific structures, especially the barrel, screw.

 The arrangement of the thrust bearing gearbox is more complicated, resulting in an increase in equipment cost. For example, the single-screw adopts a belt for primary transmission, while the twin-screw fish floating feed machine adopts a gearbox for transmission. The two have great differences in manufacturing and transmission efficiency.

1. Working principle of fish floating feed machine

The working principle of the floating fish feed making machine is actually relatively simple. As we mentioned in the overview of the floating fish feed extruder, the floating fish feed pellet mill uses mechanical energy to convert thermal energy to provide kinetic energy. 

Usually the extrusion propulsion of the fish floating feed machine’s non-equidistant non-standard screw system, the gas in the material is discharged and quickly filled with the material.

The material is backflowed by the shear force, which increases the pressure in the fish floating feed machine chamber. At the same time, the mechanical energy is converted into heat energy through the friction of the material in the chamber, so that the material It becomes a gel state with flowing properties.

When the material is squeezed to the outlet, the pressure changes from high pressure to normal pressure instantaneously, and from high temperature to normal temperature instantaneously, resulting in the rapid evaporation of water from the tissue structure.

The friction between the materials fully mixes, squeezes, heats, glues, and gelatinizes the material to produce tissue changes. The original structure of the fish floating feed machine is destroyed, and countless microporous structures are formed inside. Then, through the cutting device, the puffed food is formed after cutting and cooling.

2. Main use of fish floating feed machine

The main purpose of the fish floating feed machine extruder is self-evident. The main function of all fish floating feed machines is to puff up food. It can make the food larger and looser after processing. The main purpose of the puffing machine is to puff up the food.

The puffing in the extrusion cavity is actually a high temperature and instantaneous process, which plays a very good role in the processing of food raw materials. The state of “popcorn” not only changes its physical state, but also changes its internal organic molecular structure, making the starch easier to digest and the protein easier to use.

Compared with ordinary full-price granular foods, puffed food made by floating fish feed pellet machine have its unique advantages.

  • The palatability of food is improved. After the food raw materials are puffed, the aroma is increased, the palatability is improved, and the appetite of animals can be stimulated.
  • The digestibility of food is improved. After the food is puffed, the degree of changing the long-chain structure of protein, fat and other organic matter into short-chain structure increases, so it becomes more digestible.

How are poultry feed pellet making machine ingredients?

Before planning and designing the automatic control system for the batching and mixing process of the poultry feed pellet making machine, it is necessary to understand the operating characteristics and requirements of the relevant process.

For the current common batch batching and kneading processes of poultry feed machinery, whether it is a multi-silo-weighing-stirring-stirring-stirring system, there are the following common operating characteristics and requirements:

(1) It is a repeated batch operation, each batch of ten simple processes from different raw materials, such as weighing, mixing, mixing, and discharging, are completed in sequence or time.

All kinds of feeding devices, scales, scales, bucket doors, and discharge ports of mixers must move in the specified order or condition. Each poultry feed making machinery and equipment implement the necessary self-locking and interlocking.

(2) The material difference of multiple materials (such as different particle size, bulk density, moisture content, etc.) makes it easy to have different batching accuracy when using the same batching machine to batch different materials.

(3) The formula is often changed or modified due to the need to adapt to the different requirements of feed product users or the stock of raw materials. The system needs to have storage capacity that can store multiple recipes.

(4) Ensure the accuracy of poultry feed pellet making machine ingredients.

(5) Real-time monitoring of the material level of the material warehouse to ensure continued production.

(6) The products in the batching and mixing section can be used as finished products or semi-finished products. The basic data of the production process are important information for the production management, inventory management and raw material management of the entire poultry feed  mill factory.

The basic principles of batching design and automatic control of production process are put forward, and the operating process characteristics and requirements of these processing equipment are presented. In planning and design, the requirements of each running process must be considered, so that the system has corresponding control functions.

Because of its practical craftsmanship, excellent quality and excellent service, its products are sold all over the country, and some products have gone to the world and are more and more recognized by the feed industry.

1.What determines the length of feed pellets?

What is the factor of the feed length of the poultry feed pellet making machine? There are many goals to measure the quality of poultry feed pellet making machine, and the discharge length is one of them. Of course, there are many factors related to the discharge length of the poultry feed making machine. Only by fully grasping it can we meet the needs of customers.

Through experimental analysis, the poultry feed pellet making machine manufacturer found that when other parameters of the poultry feed equipment are the same, the higher the output value, the longer the length of the straw pellets, and the length is proportional to the output value.

Poultry feed pellet making machine manufacturers also have a certain relationship with the ring die speed of the feed equipment, and it is still inversely proportional. That is to say, the higher the speed of the ring die, the shorter the feeding length of the feed equipment; on the contrary, the longer the feeding length, the user can adjust the speed according to their needs to meet their respective production needs.

In addition to the above two points, the diameter of the ring die, the number of openings, the density of the raw material and the water content will also affect the discharge length of the straw pellets. Therefore, the raw material should be processed to a moisture content when producing pellets of matter.

2.What equipment does a complete poultry feed pellet making machine line include?

The poultry feed pellet making machine line generally includes crushing, stirring and pelleting. The main function of the crushing part is to crush and process corn, beans and other particles into powder materials. The equipment includes: single electric crusher, multifunctional hammer crusher, claw crusher, water drop type high-efficiency crusher, large crusher, bean cake crusher, etc.

The single electric poultry feed pulverizer adopts 220V single electric power, and the hourly output is 100-300 kilograms. The multifunctional hammer crusher is the SFSP model of small and medium feed mills, with a wide range of applications, high efficiency, and large output. The hourly output is generally 800-2000 kg, and the motor is 7.5-15KW.

The crushing principle of the claw crusher is solid, so it can crush smaller materials, but the production efficiency is low, the hourly output is generally 300-800 kg, 5.5-11KW motor.

Large and medium-sized poultry feed mills use large crushers, which have large output and high efficiency, but large energy consumption. The hourly output is 2000-6000 kg, and the motor needs 18.5-37KW. Water drop high-efficiency poultry feed crusher is a new energy-saving product.

The crushing chamber is shaped like a falling water drop. Large screen angle, high production efficiency. The same output can save 10-20% energy than other crushers. The bean cake crusher is a special poultry fed grinder machine for crushing bean cakes. It can crush bean cakes with a diameter of φ600mm and an hourly output of 1000-5000 kg.
