Applications Of Shrimp Feed Pellet Machine

With the increasingly fierce market competition, the past days of high profits for feed producers are gone. Now shrimp feed producers, shrimp feed suppliers, shrimp feed factories, and shrimp feed companies are almost operating at meager profits; in addition, the homogeneity of feed products is increasing. The more serious it is, the more intense the market competition is.

This situation requires the aquatic feed factory to find various methods in the shrimp feed machine and shrimp feed production technology to reduce shrimp feed mill production costs, improve product quality, and ensure the competitiveness of products and shrimp feed plants in the market.

Compared with fish, shrimps and crabs have different requirements for shrimp feed production technology due to their nutritional requirements, physiological functions and living habits.

  • High requirements for the palatability of feed;
  • High requirements for the adhesion of feed;
  • High requirements for feed crushing fineness;
  • The requirements for protein and fat are higher than fish and terrestrial animals. This requires full consideration of its special requirements during the processing of compound feed for shrimp and crab. In the shrimp feed production process, scientific quality standards should be selected, appropriate processing machinery and reasonable shrimp feed techniques should be adopted to ensure the processing quality of shrimp and crab feed.

Working Principle Of Shrimp Feed Pellet Machine

The processing method of the shrimp feed pelletizer is that various raw materials are accurately weighed by the batching scale, and then pulverized by a micro-pulverizer and then mixed in the shrimp feed mixer. After the materials are evenly mixed, they enter the conditioner for conditioning, and then shrimp feed are pressed into pellets by the shrimp feed pellet making machine, and finally cooled by the cooler to obtain the final product.

Different Shrimps in different growing stages have different demands for feed pellet size, therefore, choosing the right crushing technology and shrimp feed machine is very important.

fish feed production machine from China

The feed processing industry has undergone tremendous changes in the past 20 years. Expansion processing of poultry feed and piglet feed, as well as extrusion processing of fish feed have been generally accepted and adopted.

However, pelleting technology by shrimp feed pellet machine is still used in the production of shrimp feed, because the cost of pelleting by shrimp feed pellet machine is lower than expansion and extrusion by shrimp feed extruder machine, and shrimp is eaten underwater. As long as shrimp feed manufacturers can find ways to improve the water stability of pellets, they can avoid using extrusion method to produce shrimp feed.

Optional conditioner for shrimp feed pellet mill machine

In general, the equipped conditioner for shrimp feed pellet making machine consists of:

  1. Differential Diameter Conditioner
    This is used for pre-cooking of the material, steam enters through the nozzles and is mixed with the raw material.
  2. Long Term Conditioner
    This is used for retention time during cooking, usually placed below the DDC, to prolong the material cooking time.
  3. Single Shaft Conditioner
    There are two kinds of SSC, with and without heat jackets. The SSC is used for heating the material (by heat jacket or direct steam injection), breaking lumps that are formed in the LTC, and continuous feeding to the shrimp feed pellet mill.

Based on the raw materials and formula of shrimp feed and your shrimp feed process requirements, we can customize and configure your shrimp feed pelleting system for you. Investigate the marketing channels and determine the type of feed to be produced. Including feed quality and output requirements, and determining the formula for feed processing.

How to identify the production quality of shrimp feed made by shrimp feed machine

There are many shrimp feed types, and the same type of shrimp feed also has different grades of products, and its quality requirements are also very different. This requires some standards for judging the quality. In general, it can be judged whether the quality of the shrimp feed is good or bad.

how to make shrimp feed

  1. Feed appearance of shrimp feed made by shrimp feed making machine
    The appearance of shrimp feed is the primary criterion, and the market's acceptance of a feed largely depends on the appearance. The surface of the better shrimp feed should be smooth, the cut is flat, the size is uniform, the length is the same, and the color is uniform;
  2. Water resistance of shrimp feed made by shrimp feed pellet machine
    If the appearance is to judge the "appearance" of the shrimp feed, and the water resistance is to judge the "intension" of the shrimp feed. The shrimps remain granular before eating, which on the one hand helps to promote the eating of the shrimps, on the other hand, it is also beneficial to keep the nutrients of the feed from losing, protect the water body, promote the digestion and absorption of the shrimps to the feed, and increase the ratio of feed to meat.
    The water resistance of shrimp feed requires that the feed can be fully softened within 20-30 minutes after soaking in water. There is no hard core in the feed when it is kneaded by hand, and it will not spread when it is flattened. After 2-3 hours of water resistance, the feed will swell without falling apart or breaking.
  3. Powdering rate of shrimp feed made by shrimp prawn feed machine
    Another important indicator for measuring shrimp feed is the powdering rate. The powdering rate is that a fixed weight of shrimp feed (500g) passes through a rotating box for 10 minutes, and after 500 impacts, it simulates the force that shrimp feed receives during transportation, cooling, and packaging, and then weighs the resulting fine powder to determine the proportion in the feed.
    Reducing the powdering rate of shrimp feed can effectively reduce the waste caused by the dissolution of feed powder in water, protect water quality, and effectively reduce feed cost and bait coefficient.
  4. Color of shrimp feed made by shrimp feed machine
    The color of shrimp feed is not only related to the granulation process, but also affected by the post-curing effect. A better shrimp feed should be consistent in color, uniform and oily.

What factors will affect the formulation of shrimp feed?

Two perspectives are influencing the formulation: culturing performances and efficiency of the machinery. For example, choosing the right starch source (types of flour) is essential. Inappropriate starch sources will lower the steam incorporation level and causes jams at the pellet mills.

Fat and moisture content play inseparable roles in the hammer mill and pulverizer throughput. Formulation with high fiber content not only increases the risk of broken pellets, lowering the water stability of the pellets.

High fiber content also increases the wear of all machinery in the process. Reducing the use-life of the parts such as the hammers, screens, and dies.

In the shrimp feed processing technology, why is it necessary to use two crushing processes?

We firmly believe in the benefit of even particle reduction to ultra-fine powder. The typical target is to reach more than 95% passing through a 60 mesh screen.

It is impossible to efficiently produce small-size products with size 2.0 mm and below without this ultra-fine grind process. Ultra-fine grinding will increase production efficiency and end product quality during the production of larger-size products. It will also open the possibility to utilize less expensive starchy ingredients.

RICHI Machinery understands that many production practitioners might worry about the extra energy cost of utilizing a pulverizer, which is why we designed a revolutionary pulverizer that runs at much lower energy costs.

The ability to substitute with cheaper ingredients cost will compensate for the small extra energy requirement of the pulverizer. The ultra-fine raw material will produce smooth, shiny, and water-stable products.

In a shrimp feed processing plant, is it necessary to add a pre-hydration process?

We always recommend the pre-hydration in pre-pelleting mixers. The hydration of dry ingredients at this production stage improves the throughput, lowers energy costs, and increases product quality.

To evenly feed the pre-hydrated mix to the pellet mill, we supply an activated semi-cylindrical hopper system, with slowly rotating paddles.

With over 30 years of experience, we have enabled our customers to rapidly grow with our shrimp feed pellet machine, shrimp prawn feed making machines and complete shrimp feed mill plant solutions. The some leading feed companies in Asia are relying on RICHI’s innovative technologies.
