Abstract

The invention discloses density control equipment for aquatic puffed pellet feed. The equipment includes a cutting device, a buffer feeding device and a sealed pressurizing device, wherein the cutting device is used for cutting puffed pellet feed discharged from a puffing cavity into pellets; the buffer feeding device is used for buffering the falling pellets, and the sealed pressurizing device is used for performing pressurization, sealing and volume-weight increasing on the pellets falling in the sealed pressurizing device; the sealed pressurizing device comprises a sealed pressure stabilizing chamber, an impeller body, a spindle and a drive component; the lower end of the sealed pressure stabilizing chamber is provided with a discharge hole; a plurality of blades are arranged on the impeller body, and the blades are provided with sealing pieces matched with the sealed pressure stabilizing chamber; a pressurizing chamber is formed between every two adjacent blades; and a sealed pressurizing space is formed among a cutter housing, the buffer feeding device, the sealed pressure stabilizing chamber and the impeller body. According to the density control equipment for aquatic puffed pellet feed, positive pressure air is introduced into the sealed pressure stabilizing chamber to make pellet texture denser, the volume-weight is increased, and required heavy pellet products are finally obtained.

Description

technical field [0001] The invention relates to the technical field of extruders, in particular to a device for controlling the density of aquatic extruded granular feed. Background technique [0002] With the development of the aquaculture industry and the improvement of domestic environmental standards for aquaculture water, the country has strengthened the supervision of aquaculture drainage from the legal level, and farmers have switched from the previous granulation sinking feed to feeding extruded sinking feed. Extruded sinking feed has good maturity, good stability in water, is not easy to disperse when put into water, low pulverization rate, good absorption of fish, clean excretion, and less pollution to water, but the density of extruded feed is light and bulk density is low, and it is easy to float. Inconvenient to operate. In this case, there is an urgent need to develop density control equipment for extruders to solve the problem of difficult sinking with extrud...
