Expanded feed density control device

Abstract

The present invention discloses an expanded feed density control device and belongs to feed production devices. The expanded feed density control device comprises a box body and also comprises a rotating shaft, two bearings, a driving motor, and blades; the box body is provided with a feeding hole and a discharging hole; the rotating shaft is positioned inside the box body; the number of the bearings are two, the two bearings are fixed on both sides of the box body, and the two bearings are respectively positioned at two ends of the rotating shaft and used for supporting the rotating shaft; the driving motor is fixed with the box body and an output shaft of the driving motor is in transmission connection with the bearings; and a plurality of the blades are arranged, the blades are radiallyuniformly distributed along circumference of the rotating shaft, one side edges of the blades are fixed on outer edges of the rotating shaft, and anti-sticking layers cover outer surfaces of the blades. The anti-sticking layers play functions of preventing materials from sticking on the blades, can alleviate a problem of material sticking by a great extent, and have an advantage of more smooth material falling.

Description

technical field [0001] The invention relates to feed production equipment, in particular to a device for controlling the density of extruded feed. Background technique [0002] Density control is the most challenging part in the production of extruded feed, especially in the production of aquatic feed. The sinking feed should basically sink in the expected way. If the sinking feed floats on the water, it will not only reduce the feed conversion rate, but also pollute the environment as a wasted nutrient. When using an extruder to produce "low-energy formula" sinking feed with relatively low oil content, the difficulty is even greater. [0003] However, in the existing density control equipment, during the production process, the material is easy to stick to the rotor, so that the phenomenon of not cutting the material occurs. The phenomenon of being stuck, there is a problem of poor blanking smoothness. At the same time, when the rotor rotates at a high speed, some materi...
