Dog Food Twin Screw Extruder

Double Screw Extruder; Twin Screw Extruder.

It is the process of feeding raw material through screw that causes kneading, grinding, mixing, inner shear force. This time heat has been occurred and cell wall will break away. The factor of heat, moisture, high pressure, time make material cooked. Starch will change status to gelatin called “Gelatinization” . Mean time the structure of starch, protein, fat will be changed  call “Plasticization” . This can form many shapes as require.

Since the pressure inside screw is higher than atmosphere pressure, when material pass  DIE out. The pressure has been changed rapidly that causes blast and expansion. Air bubbles will take place. Extrusion process also can be called as HT/ST process (High Temperature / Short Time)

1. Alloy (38CrMoAL) screw made by nitriding process, high strength and wear-resting. Self-cleaning ability, no need to discharge or clean the barrel and screw when roasting or replacing of materials.

2. Adopting speed-adjusted converter on feeding system, extrusion system and cutting system. Food grade stainless steel twin screw feeding machine, stable materials feeding in the whole food process.

3. Gearbox with automatic lubrication function, extending gear life.

4. World famous brand Siemens main motor, guaranteeing good quality

5. Increased radiator on driving part for forced cooling effect, ensuring extruder operates safely.

6. Cutting knife fixed in the die head seat, rotary cutting by V-belt drive.

Feature:

-Extruder is mainly composed of feeding, pre-conditioning, extrusion and cutting system

-Main engine adopts inverter to adjust speed of screw according to changing of formula

-Wear sleeve and screw sleev are made of high wear-resistant alloy steel, to reduce abrasion and prolong service life

-Twin screws adopt building block system (BBS) to be adjustable for different technollogy

-Doule-shaft pre-conditioner makes excellent result of mixing and conditioning, increasing capacity of extruder 10-15%

-Diameter of feed Φ1.2-Φ12 can satisfy feed production for dog, cat, tortoise, bird, seafish, shrimp and pet fish ect.
