The invention discloses a 3D food printing pretreatment
system and a printing device.The 3D food printing pretreatment
system comprises a
machine body, a crushing device, an extruding device, a heating device and a collecting device.The crushing device is used for crushing unfrozen meat and uniformly mixing the meat, and the extruding device is used for extruding materials discharged by the crushing device; the heating device is used for heating materials extruded by the
extrusion device, and the collecting device is used for collecting the materials heated by the heating device.
Meat fibers are fully crushed and uniformly mixed with
powder and water to form homogeneous
slurry, so that the fluidity and
extrusion stability of materials are improved, and plug blockage or fault caused by uneven particles in the 3D printing process is avoided. According to the method, extruded materials are heated, meat
protein and added
powder are promoted to be partially gelatinized in advance, the self-supporting performance of the materials is enhanced, the printed structure is not prone to collapse, and after the materials are heated, microbial loads can be effectively reduced, and the
shelf life of the follow-up printed materials is prolonged.
