Fish feed cooking and crushing device

Abstract

The invention provides a fish feed cooking and crushing device, and belongs to the technical field of fish meal processing equipment. The device comprises a cylinder body, a stirring cylinder, an electric heating pipe, a stirring mechanism, a driving mechanism, a mincing mechanism and an extruding mechanism, a cavity is formed in the cylinder body, the stirring cylinder is coaxially and fixedly arranged in the cavity, the stirring cylinder comprises a first straight cylinder part, a conical part and a second straight cylinder part, and a first rotating shaft is coaxially and rotationally arranged in the first straight cylinder part; the lower end of the second straight cylinder part communicates with the discharging hole, the electric heating pipe is wound in a cavity located in the outer side of the first straight cylinder part, the stirring mechanism can drive fish feed in the first straight cylinder part to move downwards, the driving mechanism can drive the first rotating shaft to rotate, and the mincing mechanism can mince the fish feed moving into a conical part. and the extrusion mechanism can extrude the fish feed moving into the second straight cylinder part out of the discharge hole and extrude out water in the fish feed. The fish feed can be uniformly heated, and meanwhile, the heated fish feed can be minced and subjected to preliminary dehydration treatment.

Description

technical field [0001] The invention belongs to the technical field of fish meal processing equipment, and relates to a fish feed cooking and crushing device. Background technique [0002] In the fishmeal production process, the fish feed needs to be cooked first, and the fish feed is cooked to a certain extent through the cooking equipment, so that the fat cells of the fish body are completely ruptured, which is convenient for the next process. [0003] Existing cooking equipment usually includes a cooking cylinder and a stirring rod. The fish material is put into the cooking cylinder, and the fish material in the cooking cylinder is heated by electric heating or steam heating, and the stirring rod is constantly stirring the fish material, but due to the stirring The stirring range of the rod is limited, and the fish feed in the cooking cylinder cannot be moved as a whole, so that the fish feed is heated unevenly, and the fish feed attached to the wall of the cylinder is ea...

AI Technical Summary

Problems solved by technology

[0003] Existing cooking equipment usually includes a cooking cylinder and a stirring rod. Put the fish material into the cooking cylinder, use electric heating or steam heating to heat the fish material in the cooking cylinder, and at the same time, the stirring rod continuously stirs the fish material, but due to the stirring The stirring range of the rod is limited, and it is impossible to make the fish food in the cooking cylinder move as a whole, so that the fish food is heated unevenly, and the fish food attached to the wall of the cylinder is easy to be overcooked

In addition, the cooked fish material has a high viscosity and has not been cut into small pieces, which may block the discharge port, affect the normal discharge, and reduce the cooking efficiency
