RICHI has engaged in aquatic feed making machine for 25 years and thus has rich experience on feed machinery after repeated attempts and trials.Nowadays we serves the aquaculture industry with high-quality, robust equipment for fine-grinding and pelleting
Our solutions come in a modular design so you can customize them to match your production process. At RICHI we focus on solutions that pay off, whether it's supplying the smallest spare part or serving as a long term partner. Complete Crab Feed Pellet Production Line includes the following equipments, from the storage of raw materials to the packaging of the final pellets. Each section has professional equipment to work. Of course, according to the different needs, it may be the particularity of the raw materials or the limitations of the site. Our engineers will redesign the process, and the equipment used will be increased or decreased. Click each module below, you will see the specific equipment information.
Lump raw materials must be crushed before they can be batched. After the raw materials enter the cleaning screen, the impurities in the raw materials are separated, and then the iron filings are removed by the magnetic separator. It is very important to remove impurities and iron. It can not only ensure the quality of crab feed, but also protect the equipment and extend the life of the equipment.
Primary coarse crushing is the pretreatment process of ultra-fine crushing in aquatic crab feed processing. The main purpose is to reduce the particle size difference and variation range of the material, improve the working condition of the ultra-fine pulverizer, improve the working efficiency of the ultra-fine crusher, and ensure the stable quality.
This dosing system is designed according to different crab feed formula, is accurate weighing process of different raw materials by using specific device. The mixing system is mixing various materials under the action of external force, after various materials are metered. It is an operation that makes the raw materials distribute evenly.After the dosing and weighing process are finished, the raw materials enter the mixer for mixing, and finally the raw materials are output by conveyor and elevator.
Due to the low food intake of crab, short digestive tract, and poor digestive capacity, a secondary crushing process must be used.For crab pellet feed, the particle size of raw materials is required to reach 80-100 mesh. In this way, the quality of feed can be improved, the digestibility of shrimp feed is enhanced, and the absorption effect is good; at the same time, the particles are fine, the ability to absorb water is enhanced, the adhesion is good, and it is easy to condition and granulate.
The ultra-finely crushed materials are separated by pneumatic conveying materials, so they must be mixed again before conditioning and granulation. The trace component or liquid component is added during the second mixing, so that the material has good processing performance, so that the product quality is good. The CV value of the material mixing uniformity before granulation is less than 7%, preferably 5%.
At present, the main equipment used for this section is crab feed pellet mill,or crab feed extruder.In the extruding process, the materials are cooked under high temperature, high humidity, and high pressure for a period of time, and starch gelatinization and protein denaturation occur. The water in the feed is converted from liquid to gaseous state, and is emitted from the feed to cause the material to expand, thereby forming extruded pellet feed.With strong conditioning and appropriate crab feed formula, the requirements of this stage can also be achieved by using crab feed pellet milling machine.In the pelleting section,due to the higher requirements for starch gelatinization and water resistance of crab , it is necessary to increase the post-curing process after granulation, so that the pellet feed can be further thermally and fully cooked, which can avoid external cooked endogenous phenomena and greatly increase feed utilization rate and feed water stability.
After extruding or pelleting, the crab feed pellets (moisture in 25% ~ 30%) are formed. In order to reduce the pellet breakage, it is advisable to use pneumatic conveying to dry the material from the extruder through the flow tube to the dryer, so as to reduce the moisture of the material to about 13%.
After making crab feed pellets of a certain size, it is crushed into a qualified product with a crumbler according to the granularity of the crab feed.The screen section is mainly to screen the shrimp feed of the required pellet size. The selection of the screen can be determined according to needs. The rubber ball in the screen is best to use products with good elasticity and wear resistance, in order to improve its screening ability and service life.
After the material is dried, it enters the coating system. The feed coats the surface of the crab pellet feed with grease, vitamins, flavoring agents, etc., which not only meets the energy requirements of fish, but also reduces the loss of heat-sensitive substances during processing. And it can improve the palatability of the crab feed and reduce the powder content.
A large amount of cold air takes away the heat and some moisture of the crab feed. In addition, the cooling should not be too rapid, which can prevent the surface of the bait from being rapidly dehydrated before the internal surface is dehydrated and causing fine cracks on the surface of the particles. The water content of the crab feed pellets after cooling should be less than 12%.
According to the weighing in the packaging operation, the automation degree of the filling and packaging, it can be divided into three types: manual bagging, semi-automatic bagging and fully automatic bagging. The selection of the bagging type can be determined according to the customers' requirements, the size of the crab feed mill plant and the size of the investment.
