Vertical type rapid heating device for euphausia superba

Abstract

The invention relates to a vertical type rapid heating device for euphausia superba. The vertical type rapid heating device for euphausia superba comprises a porous steam inlet tube, wherein a springis disposed in the porous steam inlet tube. The lower end of the spring is fixed inside the porous steam inlet tube, and the upper end of the spring can be compressed downward, and is fixedly connected with a steam volume control cap. A snap spring for a hole is disposed on the upper end of the steam volume control cap to limit a highest position of the steam volume control cap. Multiple sets of through-holes are disposed at different heights in the side wall of the porous steam inlet tube. Vertical type spiral scrapers are disposed in a shell. The upper end of the porous steam inlet tube protrudes out of the shell and serves as a steam inlet. The space between the upper end of the shell and the porous steam inlet tube is closed, and the lower end of the shell is a euphausia discharge port. The vertical type spiral scrapers are connected to the output shaft of a frequency conversion motor through a transmission mechanism, and the vertical type spiral scrapers are driven to rotate by the frequency conversion motor. The device has the advantages of fast heating speed, instantaneous killing of microorganisms in euphausia superba at high temperature, short duration of high temperature,less damage to nutrients in materials, and high nutrient retention rate. The device has a simple structure, occupies a small space, and is easy to implement.

Description

technical field [0001] The invention relates to an aquatic product processing device, in particular to a rapid heating device for Antarctic krill. Background technique [0002] Antarctic krill is rich in resources and has a huge amount of biological resources. It is the raw material of Antarctic krill shrimp powder. Antarctic krill shrimp meal is a kind of raw material that can be used to extract high-quality shrimp oil and process high-nutrition feed. Among them, the heating and cooking process requires short heating time, fast speed and guaranteed heating uniformity. [0003] The Chinese patent literature with the publication number CN205382140U discloses a heating and coagulation device for Antarctic shrimp. Its main shaft has no heating function, and the scraper is installed on the main shaft in parallel, so that the material cannot be propelled. The material is propelled by the high pressure formed by the screw pump, and the material is discharged more difficult. At ...

Problems solved by technology

[0003] The Chinese patent literature with the publication number CN205382140U discloses a heating and coagulation device for Antarctic shrimp. Its main shaft has no heating function, and the scraper is installed on the main shaft in parallel, so that the material cannot be propelled. The material is propelled by the high pressure formed by the screw pump, and the material is discharged more difficult

At the same time, the structure of the equipment is relatively complicated, and it is mainly suitable for heating and cooking Antarctic krill that has not been coarsely crushed.

[0004] The Chinese patent document with the publication number CN107048248A discloses a device for rapid cooking of Antarctic krill. Its key parts are divided into a preheating system and a condensation system. The propulsion effect makes it difficult to discharge materials; the spiral scraper of the condensation system is close to the inner wall of the steam sleeve and the outer wall of the main shaft, which is very difficult to manufacture, and the heat transfer efficiency is not as high as that of the scraper
