2.Model and Capacity:

Actual equipment capacity depends on the raw material formulation and pellet size.

3.Equipment Description:

3.1 Production Line Configuration:

Line configurations are individually developed based on the customer's capacity, production needs, and automation requirements. DEXIYA production lines with the a capacity of less than 1 ton/hour are mainly divided into basic, standard, and high-end configurations. Lines with the capacity of more than 1 ton/hour are equipped with a higher degree of automation, and all stages from raw material processing to finished product packaging can be controlled automatically, thereby improving production efficiency and reducing labor costs.

3.1.1 Basic Line Configuration:

The most basic feed production process includes ingredient mixing, pellet extrusion, drying, fat and flavor spraying, cooling, and finished feed packaging. The simplest configuration of a small line may be as follows:

① Mixer

② Screw Conveyor

③ Twin Screw Extruder

④ Air Conveyor

⑤ Electric Dryer

⑥ Belt Conveyor

⑦ Double Drum Oil Sprayer

We adjust the line configuration according to customers' actual production needs and provide a customized solution. For example, vertical mixer or horizontal mixer with an automatic water addition device; extruder with a pre-conditioner; multi-layer reciprocating dryer with electricity, gas, or steam as the heat source; drum or vacuum fat coater for pellets; semi-automatic or automatic packaging machine; etc.

3.1.2 Automated Line:

To ensure the production efficiency of large-scale feed production lines, a higher degree of automation is required. A complete large-scale automated line consists of various sections, from raw material processing to finished pellet packaging. The DXY premium dry fish food production line mainly includes the following sections:

①Raw Material Feeding and Cleaning Section:

Ø Raw Material Sources:

- Granular raw materials: whole grains such as wheat, rice, corn, etc.;

- Powdered raw materials: meat and bone meal, fish meal, etc.

Ø Main Tasks: iron and impurity removal.

Ø Main Process:

- Granular raw materials: raw material feeding → lifting → initial screening and cleaning (removal of large impurities) → permanent magnet cylinder (iron removal) → feeding into the crushing chamber;

- Powdered raw materials: raw material feeding → lifting → powder screening (impurity removal) → permanent magnet cylinder (iron removal) → feeding into the dosing silo.

② Ingredient Dosing and Mixing Section:

Ø  Number of Ingredients: Adjustable based on the customer's recipe and raw materials, ranging from 7–8 in simple recipes to 25 in complex ones.

Ø  Technical Process: From raw material dosing to the buffer bin, the entire process is a computer-controlled automated closed loop.

③ Raw Material Crushing Section:

Ø  Main Task: ensuring powder fineness.

Ø  Main Equipment: hammer mill. It uses high-speed rotating hammers to impact the material, as well as screens with various openings to control the fineness of grinding. For the production of fine pet food, especially for fish, where even higher raw material fineness is required, an ultra-fine grinder can be added after this stage for secondary grinding.

④ Secondary Raw Material Mixing Section:

Ø  Main Task and Function:

To thoroughly mix all powdered raw materials, such as grain meal and meat meal, that were processed separately earlier, ensuring a higher degree of homogeneity. It can be equipped with a spraying system into which a small amount of oil or liquid additives can be added to improve the quality of the final product.

Ø  Main Equipment: high-efficiency twin-shaft paddle mixer.

This type of mixer features a short mixing cycle, high efficiency, and low residue, meeting the requirements of large-scale continuous production.

⑤ Pellet Extrusion Section:

Ø  Main Task: conditioning and extrusion expansion.

Ø  Process Effects and High Standard Requirements:

- Production of various animal feeds: by changing the formulation, screws, etc., the twin-screw extruder can produce floating, sinking, and slow-sinking feeds.

- Product shape and taste formation: by changing the extrusion die, it can produce pellets of various sizes. At the same time, the high-temperature and high-pressure process gives the pellets a unique aroma, eliminates anti-nutritional factors and harmful microorganisms, and improves the hygienic quality of the feed.

⑥ Drying Section:

Ø Main Equipment: multi-layer reciprocating dryer; heat sources: electricity, gas, and steam.

Ø Features: Wet pellets enter from the top layer of the dryer, move forward along a stainless steel belt, and then fall to the next layer for reverse conveying, repeating this process to form an S-shaped path. This design significantly increases the drying time of feed within a limited floor space.

Ø Working Principle: Hot air is generated by electricity, gas, or steam and is forced to circulate inside, penetrating the pellet layer and removing moisture. At the same time, the dehumidification system removes hot, humid air and replaces it with dry air, creating a dynamic equilibrium.

⑦ Liquid and Dry Additive Spraying Section:

Ø  Main Task: applying multiple spray layers, with each layer impregnated with flavor.

Ø  The high quality of the spraying process depends on ensuring effective and uniform coating of the surface of each feed pellet with each coating component. The standard sequence is usually as follows:

- Oil spraying: First spray oil (e.g. chicken fat or fish oil). This not only increases energy value and palatability but, more importantly, provides a "binder" for subsequent powdered flavor enhancers;

- Liquid flavor spraying: Spraying liquid taste-enhancing substances or flavors to further enhance taste;

- Powdering: Dust with powdered flavor enhancers (also known as flavors). They adhere to the surface of oily pellets and come into direct contact with the pet's olfactory and taste receptors, maximizing aroma release.

Ø Main Equipment and Technological Processes: from atmospheric pressure to vacuum.

- Mixing sprayer: Generally, a twin-shaft paddle or trough mixer is used as the mixing chamber. The components are intensively mixed inside, and the nozzle sprays the mixture, while the mixing time can be precisely controlled.

- Vacuum fat coater: Using pressure difference, air is evacuated from the pores inside the pellets by vacuum, after which liquids such as oil are sprayed under vacuum. Finally, the pressure is released, forcing the liquid into the pellets. Fully automated PLC control precisely controls vacuum pressure, liquid addition, and the spraying cycle, ensuring stable spraying results and consistent product quality for each batch.

⑧ Finished Feed Packaging Section:

Ø Cooling before packaging is the final stage in the pet food production line. Its main task is to rapidly and evenly cool the dried and flavored pellets to nearly room temperature, preparing them for subsequent weighing and packaging.

Ø Packaging is the final stage of the pet food production line. Its main task is to accurately, efficiently, and hygienically package the cooled finished pellets from the previous stage into final retail packaging according to specified specifications. This is a highly automated process that is crucial not only for the product's appearance but also for ensuring its quality, extending shelf life, and ultimately delivering it to consumers.

Ø Main Equipment: automatic multi-head packaging machine for pre-made bags or roll-film bags.

7.Vacuum Fat Coater for Feeds:

The vacuum fat coater uses negative-pressure technology, allowing fat to penetrate into the fish feed pellets. This reduces the leaching of fat from the pellets into water, thereby reducing water surface pollution. In addition, because the fat remains inside the pellets, it prevents water from entering, playing a key role in barrier and moisture-proof protection, keeping the pellets dry, which helps with preservation and extends shelf life.

The vacuum fat coater can add oil, fat, and dry components to feeds. The spray volume and time are adjustable via the control panel. Advantages of vacuum fat coating:

- High fat content: allows the addition of 20–30% or even more fat, significantly exceeding the performance of atmospheric-pressure spraying;

- Improved pellet quality and extended shelf life: the liquid is absorbed into the pellets rather than simply adhering to the surface, resulting in a drier product appearance and reduced oxidation;

- Improved nutrient absorption: fat penetrates into the internal pores, facilitating digestion and absorption of the feed by animals.

Vacuum fat coating is suitable for producing high-quality feed, especially fish feed. Because the fat penetrates into the pellets, it is less likely to dissolve in water. This results in less water pollution after feeding. Fish can consume whole, nutrient-rich pellets for longer, reducing feed loss.

The application of fat and dry flavoring to pellets is the most important stage in the pet food production line—a stage that “breathes soul” into extruded pellets, a magical step that turns nutritional recipes into feed that pets truly love.
