Fish meal production line
Fish meal is a kind of nutritious materials that can be further processed for making animal feed, such as cat and dog food, rabbit food and all kinds of poultry feed. Due to its high protein and nutritional value, it is very popular in the animal feed market, therefore, fishmeal making has become a promising business in recent years. To make fish powder, it is necessary to adopt a special processing craft and a series of fish meal production equipment as support. The whole Shuliy fish meal production line mainly includes the steps of fish cutting, fish cooking, fish squeezing, fish powder drying and screening, and fish meal packaging.
Fishmeal is a kind of commercial product that is processed by the fish after removing the edible parts for human consumption or lacking market value. Fishmeal is a kind of brown powder. Specifically, it is a product made by crushing, squeezing, drying, and degreasing the above-mentioned various types of dead fish, small fish and fish processed scraps, shrimp, crab, mealworm and so on. The purpose of fishmeal is that it is rich in protein and can be added to the animal feed.
Fish meal making
1. Fishmeal does not contain difficult substances such as cellulose, which is difficult to digest. The fish powder has a high effective energy value, so it is easy to formulate high-energy animal feed using fishmeal as raw material.
2. The fish powder is rich in B vitamins, of which vitamin B12 and vitamin B2 are very high. It also contains fat-soluble vitamins such as vitamins A, D, and vitamin E.
3. Fishmeal is a good source of minerals, calcium, phosphorus content is high, and the proportion is appropriate. In addition, the selenium content of fish powder is also very high, up to 2mg/kg. In addition, the content of iodine, zinc, iron, and selenium in the fish meal is also high and contains an appropriate amount of arsenic.
4. The fish meal contains an unknown factor that promotes growth. Although this substance has not been purified into a compound, it has been approved to stimulate the growth and development of animals.
The common fish meal processing procedure is big fish cutting——fishing cooking——cooked fish squeezing——fish powder drying and screening——fish meal packaging and fish oil processing.
Processing steps of the fish meal production line
If your raw materials are just the small size of fish, shrimp, and mealworm, you may pass this step for transporting them into the fish cooking tank by a screw conveyor. However, if your fish with big size, you should use an automatic fish cutting machine to cut them into small pieces with the size of less or equal to 5 mm first.
The crushed fish pieces will be delivered into the fish cooker machine for cooking for about 20 minutes. The fish cooker adopts the steam heating method so that it should match with a boiler for providing the steam source. The cooking temperature in the fish cooking machine is about 150℃-160℃. The boiler can be bought or self-built by the customers themselves. This fish cooking step has two main functions for processing fish meal: cooked and sterilization.
The cooked fish pieces then are transported into the fish squeezing machine for pressing out the water and fish fat quickly. This screw juicer machine can squeeze out the juice products such as fish oil and water of the fish to the maximum extent, and discharge the finely divided fish meat and fish residue from the slag discharging outlet. In fact, these processed fish residue and finely fish meat is the crude and wet fish meal, which should be further processed for making fishmeal. As for the extracted oil-water mixture, they can be further processed to making fish oil and fish protein production.
After pressing, the fish residues still have a certain amount of water content. Therefore, we should use the fish meal dryer machine for fast drying. This rotary dryer machine can dry the fish meal quickly during its rotation process with the heating source of boiler steam. This dryer machine has a fully enclosed structure and equipped with a dust collector so that there will be no dust pollution occurred.
After drying, the fishmeal should be screened by a drum screening machine for getting the fish powder with even size. The drum screening machine can be changed with different screen meshes with different screening holes. After screening, the fine fish powder can be packed, and the fish powder which is not the required size(usually 3 mm) can be crushed again by a small crusher machine with a dust collector to ensure the non-pollution environment. Then, all the fish meal can be packed.
The final fishmeal can be bagged manually or packaged into individual small packages by an automatic packaging machine. We can provide the special packaging machine for high-efficient quantitative packing of fish meal products with the customized logo, letters, brands, pictures and so on.
Fish meal plant can dry the powder and granular materials with special requirements . In order to achieve a good condition , the test operation experiment of the fishmeal machine is required.
The specific requirements are as follows:
After completing the above trial operation steps of the fish meal plant , if there is no abnormal phenomenon , you can start the formal use.
Our fish meal processing plant has special screw conveyor , with its simple structure and low cost . It is a conveyer commonly used in industry . The fishmeal conveyor is reliable , easy to maintain , and occupies a small area . Therefore , it can increase the production efficiency of fish powder and save a lot of labor cost.
In industrial production , it is inevitable to produce some waste gas, smoke and industrial dust . If these pollutants are discharged directly into the atmosphere , they will not only pollute the air , but also do harm to people’s health.
In order to prevent the above problems , we equipped a special air purification unit in fish meal processing plant , which is spray tower . The spray tower is also known as spray deodorant equipment , spray purification tower or spray scrubber . It can effectively collect dust and harmful gases through multiple filtrates. The innovative and advanced performance of fish meal equipment
Fishmeal has a high protein content and is mainly used in animal feed. Because of its extremely high economic value, investors in many countries have started to establish fish meal processing plants to produce a variety of high quality fishmeal on a large scale.
Recently, a Libyan customer placed an order with us. His factory is located by the sea and the main raw material is white fish.
