Optimization Design of Sea Cucumber Cleaning Parameters by Water Jet

Abstract

Aiming at the problem that the cleaning effect and surface integrity of the mechanical cleaning process cannot be solved simultaneously in the pretreatment of sea cucumber and according to the requirements of high efficiency, high quality and economy of sea cucumber body surface cleaning, a continuous directional cleaning device for sea cucumber abdomen and back based on the principle of water jet is designed. Through single factor experiment, the influence trend of jet parameters such as jet pressure, target distance and incidence angle on cleaning effect was analyzed. The cleaning parameters of sea cucumber are optimized by L9(3 4) orthogonal design. The experimental results show that the cleaning effect of sea cucumber is closely related to the impact of water jet. Enhancing the impact of water jet will not only help improve the cleanliness of sea cucumber, but also increase the risk of skin damage of sea cucumber. T he influence order of water jet parameters on the cleaning effect of sea cucumber is as follows: Jet pressure > jet target distance > jet incidence angle. When the jet pressure is 3.0 MPa, the jet target distance is 200 mm and the jet incidence angle is 70°, the cleanliness and integrity scores are 8.0 and 8.2 respectively and the comprehensive cleaning effect of this scheme is optimal. This study provides the basis for the research and development of sea cucumber water jet cleaning device and process optimization.
