Large-scale dog food processing equipment for Africa arranged for shipment

On September 6, 2017, the large dog food processing equipment ordered by an African customer was loaded into containers and shipped!

Process composition of the pet feed production line:

Mixer: Thoroughly mix raw materials such as corn flour, rice flour, soybean flour, fish meal, meat meal, grain flour, and additives with a certain proportion of water until evenly blended.

Feeder: Uses a motor-driven screw conveyor to transport the mixed raw materials to the feeding hopper of the twin-screw extruder. This equipment enables fast and convenient feeding, saves labor, and is highly efficient.

Twin-screw feed extruder: Under high temperature and high pressure conditions and the extrusion of the twin screws, the starch structure in the mixed raw materials changes, becoming easily absorbable nutrients. The material is extruded through a feed die, and by adjusting the rotation speed of the cutting motor, feed pellets of uniform size and length are produced. The specific pellet size and shape can be obtained by changing the die. The feed extruder adopts advanced variable frequency speed control technology, which is more energy-efficient and provides more precise speed control. The current and speed during motor operation can be directly viewed on the inverter panel, ensuring equipment safety.

Conveyor: Transports the produced feed pellets into the multi-layer drying equipment.

Multi-layer Oven: The oven is available in electric, oil-fired, gas-fired, and steam types, with temperatures ranging from 0 to 150 degrees Celsius, adjustable via the control cabinet. The interior features a stainless steel mesh belt for smooth transportation and low failure rates. Feed pellets circulate through multi-layer S-shaped tracks, drying them to a safe moisture content and extending shelf life.

Spray Seasoning Line: The oil sprayer applies oils, attractants, etc. The seasoning drum comes in octagonal, cylindrical, single-drum lifting, and double-drum seasoning line configurations, configured based on output and product properties. It sprays oil onto the feed surface while evenly distributing minced meat and spices. This process also removes burrs and rough edges from the feed pellet surface, making it smoother.

Cooling conveyor: reduces the surface temperature of dried feed pellets, promotes fat solidification, lowers pellet temperature, and facilitates packaging.

Vibrating screen: removes excess scattered material and pellet debris, ensuring quality while enabling raw material reuse.

Packaging machine: manual sealing machines and automated packaging machines are available; for details, please contact the manufacturer.

Advantages of Datong Machinery's large-scale feed equipment:

(1) All models of the main machine can be equipped with a computer automatic control system, advanced touch operation, convenient, simple, and safe.

(2) The main machine, feeder, and cutting device are all controlled by variable frequency speed regulation, ensuring uniform feeding, strong power, and stable operation.

(3) The main machine gearbox is equipped with a forced cooling gear oil pump and an automatic lubrication system, a twin-screw extrusion pumping mechanism, and a dual-shaft extended differential conditioner (optional for wet-type main machine), ensuring thorough material gelatinization with a gelatinization degree of over 98%.

(4) A wide variety of raw materials can be used, with the feed formula capable of containing over 12% fat. After adding the twin-screw steam conditioner, the fresh meat addition rate can reach up to 35%, meeting customer requirements for high fresh meat content products.

(5) The screw has excellent self-cleaning ability. There is no need to clean the barrel and screw when restarting the machine or changing material types. The main machine adopts variable frequency speed control to adapt to different raw materials, and the discharge cutter adopts variable frequency speed control to adjust the length, thickness, and shape of the material.

(6) The screw is made of special high-quality high-alloy steel, and the wear-resistant sleeve is made of bimetallic alloy material (material can be optional). The cavity is made of No. 45 steel combined with a high-hardness screw, which is more wear-resistant, has a longer service life, and can withstand greater pressure.

(7) Pet food/aquatic feed undergoes high-temperature and high-pressure sterilization during processing, ensuring the hygiene and safety of the feed product.

(8) The discharge die has cylindrical apertures with diameters ranging from 1mm to 10mm, as well as other special-shaped die holes (customizable according to customer requirements).

(9) Suitable for processing pet food pellets, ornamental fish feed/aquaculture extruded feed (floating, sinking, slow-sinking types), where the floating feed maintains stability in water for over 24 hours.
