The invention relates to the technical field of feed preparation, and discloses a feed low-temperature oil spraying
machine and a control method.The feed low-temperature oil spraying
machine comprises a box body, an oil spraying device and a
control system, the upper side of the box body is provided with an input
pipe for inputting conditioned materials, and the lower side of the box body is provided with an output
pipe for outputting the materials for puffing; the material pressing
assembly comprises a driving
assembly and two material pressing cylinders which are transversely arranged in a spaced mode, a material passing channel is formed in the radial direction of the two material pressing cylinders, and the driving
assembly is used for driving the two material pressing cylinders to rotate downwards and reversely so as to abut against the materials and drive the materials to flow into the output
pipe; the oil spraying assembly comprises an oil spraying pipe and a
temperature control assembly for controlling the temperature of the
grease in the oil spraying pipe to be 40-60 DEG C, and the oil spraying pipe is provided with a spraying head for spraying the
grease towards the
peripheral wall of the material pressing
barrel. Low-temperature oil spraying is performed after
tempering and before puffing, so that the
distribution uniformity and adhesion firmness of
grease are remarkably improved, the
water resistance and water stability of the aquatic feed are enhanced, the
nutrition and
flavor of the grease are reserved by a low-temperature process, and the nutritional value of the feed is greatly improved.
