Floating fish feed extruder for sale

1. What’s floating fish feed extruder?

Because of the advantages of floating fish feed extruder puffing, more and more feed mills have begun to puff aquafeed.

 At present, the main working principle of the floating fish feed extruder used in the floating fish feed mill is to treat the powdery material containing a certain amount of starch (more than 20%) through a conditioner, so that the moisture content of the material can reach 25% to 27%, and the temperature is raised to 80℃~100℃.

The floating fish feed extruder consists of a feeding system, a transmission system, an extrusion system, a discharging die and an electrical control system. The quenched and tempered material enters the screw extrusion zone.

Since the volume of the extrusion zone gradually decreases along the axis, the pressure on the material gradually increases, and the compression ratio can reach 4 to 10.

The material is pushed by the floating fish feed extruder screw extrusion, and accompanied by strong shear and friction, the pressure and temperature rise sharply. Under the action of high temperature and high pressure, the starch in the material can be basically completely gelatinized, and the protein is partially deformed.

(1) The whole floating fish feed extruder is made of stainless steel, which is hygienic, safe and reliable, easy to clean.

(2) The floating fish feed extruder design follows automatic assembly line production, with small footprint and less labor. The equipment is easy to operate, saving time and effort, and reducing labor consumption.

With the rapid development of the aquatic feed market, the domestic demand for aquatic feed has been driven. According to this market demand, RICHI has researched and developed various types of floating fish feed extruders.

2. Process flow of freshwater fish feed production line:

The floating fish feed extruder adopts twin-screw extrusion technology, combined with Richi Machinery’s experience in puffing technology research for many years, and is a new generation of puffed food equipment designed and manufactured to meet the needs of food and related industries.

The floating fish feed extruder production line has the advantages of stable production performance, flexible operation, fully automatic production process, beautiful appearance (using stainless steel material), etc.

Raw material preparation → mixing → conveying → extrusion → conveying → drying → oil injection → seasoning → cooling → screening → packaging

(1)Raw material cleaning

Receipt of raw corn and soybean meal in bulk; the clean-up process is all operation units that pass the corn and soybean meal that has passed the inspection of the raw material inspector into the silo.

In this process, the impurities in the raw materials are firstly removed by the impurity removal equipment, and then transported to the silo as planned by the receiving equipment and the demagnetization equipment.

 The floating fish feed extruder production line equipment includes receiving devices (such as unloading pits, platforms, etc.), conveying equipment, primary cleaning screens, and magnetic separation devices (such as permanent magnet drums, permanent magnet drums, etc.).

For the receipt of bagged raw materials, it means that the loading and unloading personnel unload the raw materials that have passed the inspection of the raw material inspectors and store them neatly in the warehouse.

In the process of receiving the goods, four points should be done:

  • Accurately count the quantity;
  • There is no quality problem in the raw materials;
  • The receiving path is correct;
  • The receiving environment is clean.

(2)Ingredient process

The batching process is to weigh the raw materials in the batching bin from the feeder under each batching bin to the batching according to the formula requirements. After each raw material is weighed by the batching scale, the raw material is transported to the powder storage silo.

 The ingredients are weighed from the silo, these weighed raw materials enter the powder silo, a small amount of material and premix are added directly and manually weighed and then put into the silo for mixing. The quality of the batching process directly affects the accuracy of product batching.

(3)Crushing process

The pulverization process means that the raw materials to be pulverized in the silo are sent to the crusher to be pulverized into powder, and then sent to the silo to be mixed by the conveyor before use. The purpose of this process is to control the pellet size of the material.

The design efficiency of the crusher in this process determines the production capacity of the process equipment, and it is also the process with the largest energy consumption in the production of powdery materials.

(4)Mixing process

In the mixing process of floating fish feed extruder plant, the crushed raw materials are discharged from the mixing bin into the mixer, and oil is added to the feed in the mixer through the liquid addition system as needed to make the components evenly mixed to achieve the desired mixing effect uniformity.

The material discharged from the mixer is the finished product, which is directly sent to the packaging process of the finished product for packaging and leaving the floating fish feed extruder production line. When producing pellet feed, the mixed powder is sent to the silo for granulation.

In order to ensure the efficiency of the mixer, maintenance personnel must regularly check and repair the equipment, and regularly test the efficiency of the mixer.

(5)Granulation process

The mixed material is quenched and tempered by magnetic separation from the granulation bin, and then sent to the compression chamber of the floating fish feed extruder, compressed into pellet feed, cooled by a cooling tower, and sieved by a screening equipment to obtain standard granules.

 Magnetic separation equipment must be cleaned regularly to prevent iron impurities from causing damage to the floating fish feed extruder. When quenching and tempering, the amount of floating fish feed extruder steam should be adjusted according to the requirements of the pellet variety, and the ring die (aperture, compression ratio, material, etc.) should be selected according to the requirements of the pellet process quality and pellet temperature and humidity.

According to the variety, indoor temperature and humidity, season and other factors, adjust the cooling tower to achieve qualified pellet temperature and humidity.

(6)Finished product packaging

The feed made by floating fish feed extruder is weighed from the finished product warehouse by a packaging scale, packed into packaging bags, then labelled and sealed by a packer, and then transported to the warehouse for stacking by a transport vehicle.

How to buy poultry food processing machine?

How to buy poultry food processing machine? If the poultry feed machine used for fish feed production or grass livestock feed production, is it possible?

poultry food processing machine

1.How to buy poultry food processing machine for fish feed?

(1) Select the power of the pellet feeder according to the amount of bait. Generally, a fish pond of 0.33-0.66 hectares (5-10 acre) has a daily feeding amount of about 120 kg, and a poultry food processing machine with a power of about 1 kg can be purchased;

For a fish pond of 0.66-3.3 hectares, the daily feeding amount is about 120-160 kg, the poultry food processing machine with a power of about 1-2 kg can be purchased; for a fish pond of 3.3-6.6 hectares, the daily feeding amount is about 600-1200 kg, and a pellet feed machine with a power of 2-4 kg can be purchased.

(2) Select the specifications of the pellet feeder according to the breeding large-scale farming. For fish ponds with a large proportion of bottom fish, you can choose a hard pellet poultry food processing machine or a soft pellet feed machine. Small multifunctional poultry food processing machine? and crushing sieve powder machine can be used in fish ponds for raising fry to obtain feed of different specifications.

(3) Pay attention to inspection when purchasing. The coating of the casing should be completely smooth, without defects such as cracks, peeling, blistering, etc.; the gear box should not leak oil; the mechanical transmission parts should be equipped with protection devices and overload protection devices, and have eye-catching lubrication, operation, rotation, safety signs;

Firmware shall not be loose; each adjustment handle and handwheel shall be flexible, light and reliable; electrical components shall be in good contact, with reliable insulation and no leakage.

(4) Power on for 3-5 minutes, observe whether the operation is stable, whether there is abnormal shock, vibration and heating, and whether the pointer of the ammeter and voltmeter are normal.

(5) Finally, don’t forget to ask for product certificate, instruction manual, sales invoice, etc.

2.How to start the poultry food processing machine?

1.Prepare to start:

Before the poultry feed pellet making machine operator is ready to start, it is necessary to confirm the material storage of each material warehouse and the residual situation of each process, understand the machine status and production schedule, open each steam trap for about two minutes, release the condensed water in the steam, make the Startup is smoother.

2.Start the poultry food processing machine:

When the main machine switch is pressed, the poultry food processing machine starts to run, but at this time the granulator has not really started, so it is impossible to granulate or add oil to clean the mold.

After the star-delta conversion of the main motor of the poultry food processing machine, after the ammeter shows that the current is normal, some grease materials should be put in first, and the poultry feed pellet making machine ring die should be washed for about two minutes to heat the ring die.

At the beginning of feeding, the feeding amount should not exceed 20% of the production capacity of the granulator, to prevent the poultry food processing machine from instantaneously feeding too much, too much negative feeding, and sudden increase in load, causing blockage or equipment damage.

When the material quality is adjusted, it can be quickly grouped, and can be dispersed after loosening. At this time, the feeding door is closed for granulation. Observe whether the current of the main machine is stable, and adjust the feed amount and steam addition amount according to the production performance and current load of the poultry food processing machine.

The amount of feed must be gradually adjusted from low speed to high speed, and the amount of steam added must be adjusted according to the dry humidity of the material. The poultry food processing machine should avoid overload, which is easy to cause ring die rupture and damage to the granulator. Don’t be careless when using new molds until the new molds are at their optimum capacity.

3.Processing grass pellets with poultry food processing machine

(1) The benefits of grass pellets

①The growth and utilization of feed is greatly affected by the season. In winter, the forage grass is withered and yellow, with little nutrition, and the livestock lack grass; in the warm season, the forage grass grows vigorously and is rich in nutrients, and many livestock cannot eat it. Therefore, in order to promote strengths and avoid weaknesses, and make full use of warm-season forages, livestock and poultry can be fed in winter.

② high feed conversion rate. Feed livestock and poultry with grass pellets in winter to use less meat. milk. Feed volume is small. The pellets are only about 1/4 of the volume of the raw hay, which is convenient for storage and transportation, and less dust is beneficial to the health of humans and animals.

③Increase palatability and improve feed quality. If the grass stream has the special smell of coumarin, the livestock will not like the food a bit, but after making grass pellets, they become palatable and high nutritional value feed.

④ Expand feed sources. Such as golden pheasant, excellent quinoa, sheep firewood and so on. Their branches are thick and hard, which are crushed and processed into grass pellets, which become the livestock’s favorite feed. Others are processed into grass pellets, such as by-products of crops. Shells, straws and various, can be used to feed livestock and poultry.

(2) Grass processing technology

① The most critical technology for processing grass granules is to adjust the moisture content of the raw materials. First, the moisture content of the raw material must be measured, and then the water is mixed to the moisture content required for processing. According to the determination, the optimal water content is 14%~16%; the forage grass is 13%~15%.

② Poultry food processing machines are usually used to process grass pellets. Grass flour is affected by stirring and squeezing during rolling. Under normal circumstances, the temperature of the pellets just coming out of the sieve will reach about 80, and the water content will generally decrease by 3%~5% from high temperature cooling to room temperature, so the water content of the cooled grass pellets will not exceed 11%~13% .

Suitable for storage due to low water content. Grass pellets with different nutrients can be prepared according to the nutritional requirements of various poultry. Its pellet size can be adjusted and processed as required.

③ Composition and effect of pellet feed

In order to produce various livestock and poultry with feed, improve the utilization rate of feed. Grass powder (green hay. Crop straw) 55% to 60%. Concentrates (corn, sorghum, oats, bran, etc.) 35% to 40%. Minerals and Vitamins 3%. 1% urea constitutes compound feed, which is pressed by pellet feed pellet machine.

During the pressing process, add 17 kg of water and 100 ml of formaldehyde liquid concentration to 37% per 100 kg to improve its nutrition and digestibility. According to the experiment, 8-month-old lambs were fattened with pellet feed for 50 days, with an average daily weight gain of 190 grams, and 6.4 kilograms of feed was consumed for each gain of 1 kilogram.

Ruminant pellet feed made by poultry food processing machine is a feasible way to promote the development of aquaculture in pastoral and agricultural areas.
