extruded dog chews food production line dry method pet

Meanwhile High quality extruded dog chews food production line dry method pet particles adjacent the screw will rotate along with screw's rotating, causing every particle adjacent the screw will rotate along with screw's rotating, causing every particles insides the chamber to posses different speed. Therefore, relative movement among particles creates heat which is necessary during manufacturing because of helping protein change properly, damage cold oil ,decrease plasticity, decrease oil, elasticity, resulting in high oil productivity.

The all-wet process uses raw coconut rather than dried copra, and the protein in the coconut creates an emulsion of oil and water.The more problematic step is breaking up the emulsion to recover the oil. This used to be done by prolonged boiling, but this produces a discolored oil and is not economical. Modern techniques use centrifuges and pre-treatments including cold, heat, acids, salts, enzymes, electrolysis, shock waves, steam distillation, or some combination. Despite numerous variations and technologies, wet processing is less viable than dry processing due to a 10-15% lower yield.
Proper harvesting of the coconut makes a significant difference in the efficacy of the oil-making process. Copra made from immature nuts is more difficult to work with and produces an inferior product with lower yields.
High quality extruded dog chews food production line dry method pet Conventional coconut oil processors use hexane as a solvent to extract up to 10% more oil than produced with just rotary mills and expellers. They then refine the oil to remove certain free fatty acids to reduce susceptibility to rancidification. Other processes to increase shelf life include using copra with a moisture content below 6%, keeping the moisture content of the oil below 0.2%, heating the oil to 130-150 °C (266-302 °F) and adding salt or citric acid.

Introduction of High automatic dog food production equipment with CE&ISO Certification

1. pet food is plant or animal material intended for consumption by dogs or other canines. In extruder, the ingredients are cooked under intense heat and pressure as it moves toward the open end of the extruder where ingredients pass through a shaping die and knife.

2. pet food Processing Line adopts corn flour, bone meal, fish meal as raw materials

3. Different shapes can be made by adjusting the dies from extruder

4. Output can be 150kg/h, 240kg/h, 500kg/h, 1ton---3ton/h

5. Flow chart:Mixing system---Extrusion system----Drying system----Flavoring system--Packing system

6. Voltage in China: Three phases: 380V/50Hz, Single phase: 220V/50Hz, we can make it according to customers' Local voltage according to different countries

7. All the machines are made by stainless steel, this line is with reasonable design and with high automation; the screws are made by alloy steel, with building block system structure and self-cleaning function

How is pet food made ?

• High quality ingredients like meal, cereals, vegetable proteins and so on are selected and ground according to the specific nutritional and pellets size requirements

• The pellet size distribution is a key factor for premium granulates production : therefore the grinding step is an important unit operation. The powder is then mixed with minor ingredients such as vitamins, mineral premixes… prior to the mixing system.

• Next, the heart of the process, extrusion cooking is done in two stages in the fish feed machine : extrusion cooking and die texturing/ shaping. Twin-screw extrusion-cooking uses its perfect mixing ability and parameters control such as shear, temperature, residence time to reach the highest physical and nutritional standards. Through direct steam injection, venting device and efficient barrel cooling, adjustable screw speed, screw configuration, shear and temperature conditions are perfectly controlled ; this leads to optimized functional and nutritional pellet properties such as the bulk density, calibration, cooking degree, best ratio proteins- lipids, etc

• Our factory offer its to heat sensitive feed, shrimp or micro feed requiring extreme drying accuracy while maintaining a very nHigh quality extruded dog chews food production line dry method pet moisture content distribution.

• Pellets can then be oil coated and possible additives and are cooled down to complete the fish feed processing.
