Working Principle Of Aquatic Feed Pellet Making Machine

The material in the extruding chamber of the fish feed making machine is subject to high pressure and temperature, making starches gelatinize and denaturing the protein, so that to improve the water stability and digestibility of feed pellet.

Meanwhile salmonella and other harmful bacterium are killed in the process. When the material goes out from the outlet of the fish feed extruder, the pressure is released suddenly and the steam blows off rapidly. Then the pellet is formed. A cutting device on the machine will cut the pellets into required length.

Grinding size of fish and shrimp feed before pelleting by aqua fish feed pellet machine

It is recommended in the fish nutrition requirement standard that the particle size of fish compound feed should be ≤0.5mm. Generally, the pulverization of the raw materials of the compound feed for fish is required to pass through a 40-mesh sieve (0.425mm sieve), and the content on the 60-mesh sieve (0.250mm sieve) is not more than 20%. The logarithmic geometric mean particle size of the fish feed should be less than 200.

Aquatic standards in different countries are different. For example, the crushing particle size requirements of China's shrimp compound feed are all 40-mesh sieve (0.425mm sieve opening), 60-mesh sieve (0.250mm sieve opening) sieve is not more than 20%, and its particle size is below 200. Eel and soft-shelled turtle feed require very fine crushing requirements.

Generally, larval eels and juvenile turtles require 98% to pass through a 100-mesh sieve, and the average particle size is less than 100; for eel and turtle feed, 98% of them are generally controlled to pass through an 80-mesh sieve. The diameter is controlled below 150.

Parameter And Model Of Aquatic Feed Pellet Making Machine

How to manufacture aqua feed? Pelletizing or extruding technology?

Due to the continuous development of the aquaculture industry and the application of pellet for fish in the aquaculture industry, the development of aquaculture towards high-density intensification has been promoted: in order to increase the conversion rate of feed and improve the environment of water bodies, the aquaculture industry has been adopting optimize the feed formula and choose the best mechanical equipment to improve the quality of pellet for.

Actually, according to the physiological characteristics of short intestines and short residence time of feed in the intestines of fish, as long as proper fish feed processing methods are adopted, it can also improve water quality, reduce fish diseases, and enhance the sustainability of the aquaculture industry. The effect of improving fish feed plant output and product quality, improving feed conversion rate and economic benefits.

Aqua feed pelleting technology VS aqua feed extruding technology

The processing methods of fish feed are mainly divided into extruded aquafeed production line technology and pellet production line technology. I believe everyone knows that extruded feed is the future trend, but there are still many aquatic feed companies and fish feed manufacturers processing fish pellet feed. Why?

Because, in addition to the customer's fish feed formula, fish feed making raw materials, fish feed plant structure, floor space and other issues, what ultimately affects the customer's fish feed making process and fish feed making equipment selection is the issue of investment cost.

Therefore, what we must promise is to customize the most economical aquatic feed production line plan for the customer within the customer's budget. In short, no matter what your needs are, we can customize the most suitable aquatic fish feed mill plant for you.

Complete aquatic feed pellet production line (pelleting technology)

The granulation processing method is that various raw materials are accurately weighed by the batching scale, and then pulverized by a micro pulverizer and then mixed in the aqua fish feed mixer.

After the materials are evenly mixed, they enter the aqua fish feed pelleting machine conditioner for conditioning, and then are pressed into pellets by the aqua fish feed pelleting machine, and finally cooled by the cooler to obtain the final product. The aqua feed pellet production line process flow is basically as follows:

The main advantages of using granulation processing method to produce aquatic animal pellet feed are high output, less equipment investment, and the extruded pellet feed does not need to be dried. It can be used as commercial feed after cooling and dissipating temperature. Its main disadvantage is the poor water resistance.

The reasons are: one is the low temperature in the process of fish feed pelleting machine granulating, and the gelatinization rate of starch is low; the other is that the water content is low.

It can be seen that in the production of aquatic animal feed using granulation processing methods, the main goal should be to ensure water resistance, and advance research should be made in terms of raw material conditioning, temperature, moisture, pressure, and the selection and treatment of binders.

Complete aqua feed manufacturing process (extruding technology)

The use of extruded aqua feed processing methods to make grains and their starches into extruded feed products or to organize plant proteins such as beans is a feed processing technology that has been developed in the past 20 years. Earlier, it was mainly used in the food industry.

After that, the aquatic animal feed produced by the extrusion method not only can add a larger percentage of starch because of the gelatinization of starch, but also has obvious disinfection and sterilization effects because of the high temperature and high pressure maturation effect.

And the extruded aquafeed production process is widely used in aquatic animal feed, especially the production of special aquatic feed. It can not only reduce feed costs, but also improve fish feed plant process characteristics. The extruded fish feed making process is basically as follows:

The principle of the puffing processing method is actually to use an aqua feed extruder to squeeze the material, and the compression ratio can reach 4-10. However, the material extruded from the aqua feed extruder, although part of the water can be removed during evaporation and subsequent transportation, the water content in the material is still high (often higher than 20%), so it must be dried.

And then cool down to reduce the moisture of the material to about 13%, and then crush, screen, and spray to obtain the required puffed pellet for fish.

Comparison of pelleting technology and extruded feed technology for aqua feed mill plant

The puffing or pelleting fish feed production systems used in feed processing plants are very similar in terms of technology. Both require raw material receiving and storage bins and a primary crushing system to crush whole grains or to further reduce the particle size. product. The batching bin, weighing hopper and mixer are used for fish feed production formulas.

In the production of most aquatic feeds, one additional crushing or final crushing is required before processing. Before granulating by fish feed pellet machine, it is often necessary to use an ultrafine pulverizer to reduce the particle size of the mixture to a fineness of 60 mesh or more, and the degree of pulverization required by the aqua feed extruder machine is 100% to pass a 40 mesh sieve.

Coarse raw materials can be used for puffing, because the materials have a maturing effect in the aqua fish feed extruder. Therefore, the difference in process between the two processing methods is mainly due to the different particle sizes required by the raw materials used.

But in terms of cost saving, animal feeding effect, water pollution and feed conversion rate, the use of extruded processing technology is obviously better than the fish feed plant's granulation processing system.

Therefore, objectively speaking, for a new aquatic feed processing plant, if the source of funds is sufficient, the extruded processing system should be adopted as much as possible. Although the one-time investment is relatively large, in the long-term benefit consideration, the extruded feed processing is still better than the fish feed pellet machine production system.

But for established aquatic feed plants, the aqua feed producers must consider adding puffing equipment on the basis of their existing aqua feed plants, because the puffing processing system can save costs. Extrusion equipment has become the tool of choice for the production of aquatic feed due to its wide range of uses.

The fish feed puffing equipment is also easy to control, and can be used to produce difficult low-starch and lowest-cost formulas, and can also use a high proportion of animal protein to produce excellent aquatic animal feed. Therefore, the use of extruded processing methods to produce aquatic feed is the preferred method for aqua feed processors, and it is also the future development trend.
