specific Embodiment approach 1

[0059] Specific implementation mode one: refer to Figure 1-14 Describe this embodiment, the production system of the salmon and trout extruded feed of this embodiment, comprise twin-screw extruder mechanism 1, stirring tank 2, vacuum spraying mechanism 3 and agitating mechanism 4, the top of agitating tank 2 is equipped with twin-screw extruding mechanism 1 , the twin-screw extruder mechanism 1 has a material inlet 5 and a material outlet 6, the twin-screw extruder mechanism 1 communicates with the top of the mixing tank 2 through the material outlet 6, and the side wall of the mixing tank 2 is processed with a vacuum port 7, so The vacuum spraying mechanism 3 is installed on the top wall of the stirring tank 2, the stirring tank 2 is equipped with a stirring mechanism 4, and the bottom of the stirring tank 2 has a particle outlet 8. So set, the twin-screw extruder mechanism 1 is used to extrude the mixed salmon and trout feed to form preliminary feed pellets, and then the fe...

specific Embodiment approach 2

[0064] Specific implementation mode two: refer to Figure 1-14 Describe this embodiment, the production system of the salmon trout extruded feed of this embodiment, such as Figure 5As shown, the twin-screw puffing mechanism 1 also includes a particle cutting mechanism 19, and the particle cutting mechanism 19 includes a cutting mechanism mounting table 191, a single-axis slide rail 192, a slider 193, a mounting seat plate 194, and a cutting motor mounting seat 195, cutting motor 196, cutting knife rod 197, cutting knife disc 198, cutting blade 199, material retaining cover 1910 and installation support plate 1911, the cutting mechanism installation table 191 is installed on the extruder shell 15, and the cutting mechanism installation table 191 Two single-axis slide rails 192 arranged in parallel are installed on the top, the installation seat plate 194 is installed on the single-axis center slide rail 192 through a slider 193, and an installation support plate 1911 and a mat...

specific Embodiment approach 3

[0066] Specific implementation mode three: refer to Figure 1-14 Describe this embodiment, the production system of the extruded feed for salmon and trout in this embodiment, the bottom of the material retaining cover 1910 has a first discharge cylinder 1912, and the side wall of the material retaining cover 1910 is processed with a square notch 1913. A rubber blocking sheet 1914 is installed at the notch 1913 . In this way, the material blocking cover 1910 is used to accept the extruded and cut feed pellets, and the pellets are input into the mixing tank 2 through the discharge port 6;

[0067] When the material blocking cover 1910 shields the extrusion die 6, the first discharge cylinder 1912 installed at the bottom of the material blocking cover 1910 communicates with the discharge port 6, and the feed particles directly enter the discharge port 6 through the first discharge cylinder 1912 Inside; when the material retaining cover 1910 moves to the edge (such as Figure 13...

Abstract

The invention relates to a production system and method for a puffed feed for salmons and trouts, and belongs to the technical field of feed preparation. The production system for the puffed feed forsalmons and trouts comprises a twin-screw puffing mechanism, a stirring tank, a vacuum spraying mechanism and a stirring mechanism, wherein the twin-screw puffing mechanism is mounted at the top of the stirring tank, is provided with a feeding opening and a discharging opening, and communicates with the top of the stirring tank through the discharging opening; a vacuum pumping opening is formed inthe side wall of the stirring tank; the vacuum spraying mechanism is mounted on the top wall of the stirring tank; the stirring mechanism is mounted in the stirring tank; and a particle outlet is formed in the bottom of the stirring tank. The production system disclosed by the invention is simple in structure and convenient to assemble, has the functions of twin-screw puffing, extruding, discharging and vacuum spraying of grease, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to an extruded feed production device, which belongs to the technical field of feed preparation. Background technique [0002] Salmon and trout can only thrive in low-temperature waters, and the upper water temperature for normal growth is very low, and there is no obvious lower limit temperature, so they are called cold-water fish. Salmon and trout each include many types, such as Atlantic salmon, Pacific salmon, coho salmon, northern salmon, etc. all belong to salmon, and rainbow trout, grayling, golden trout, etc. are all called trout. Therefore, strictly speaking, salmon trout should be called salmonids, which includes all species of salmon subfamily and whitefish subfamily. So far, scientists have used taxonomic methods to discover from the structural characteristics of fish bodies that there are 66 species of salmonids in the world. [0003] Salmon and trout are delicious and nutritious, and can be eaten fresh, salted, smo...
