Liquid Immersion Device

Abstract

The invention provides a liquid impregnation device, which can make liquids uniformly impregnated in particles without being limited by the types of liquids and particles and adjust the particle oil impregnation rate in a high-precision way. The liquid impregnation device (1) comprises a roller (3) accommodating the particles; a frame (2) supporting the roller (3) to freely rotate; nozzles (11, 11..) spraying oil towards the particles; oil supply pipes (12, 12...) supplying oil to the nozzles (11, 11..); an electric motor (5) driving the roller (3) to rotate; an exhaust pipe (14) reducing pressure inside the roller (3); and a cylinder (21) making the roller (3) swing in high speed. A protruding separation projection (9) protruding towards the inner side of the roller (3) is arranged inside the roller (3). Agglutination prevention walls (10a-10e) are vertically arranged on the upper surface of the separation projection (9). Agglutination prevention walls (10f-10h) are further vertically arranged on the lower surface of the separation projection (9).

Description

Technical field [0001] The present invention relates to a liquid immersion device for impregnating liquids such as fats and oils into pellets (feed pellets) mixed with powders such as fish meal and cereal flour. Background technique [0002] A conventionally known liquid immersion device is provided in a hollow casing with rotating members such as blades or propellers, a spray nozzle for spraying liquid, and a pressure reducing device for reducing the pressure in the casing, and particles are contained in the casing The pressure is reduced. In this state, the rotating member is used to spray the liquid from the spray nozzle to the particles while stirring the particles, so that the liquid is immersed in the particles (infiltrates into the inside of the particles). [0003] However, the above-mentioned conventional liquid immersion device has a problem in that particles are broken and pulverized due to the impact of the rotation of the rotating member, and liquid such as grease cann...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned conventional liquid immersion device has the problem that the particles are broken and pulverized due to the impact of the rotation of the rotating member, and it is impossible to uniformly impregnate liquids such as grease into the particles.

However, in the liquid immersion device of Patent Document 1, the side surface of the drum has a spherical shape protruding outward, and particles tend to gather at the center of the drum during oscillation. weight, it is difficult to adjust the ratio of oil and fat impregnated in the pellets with high precision (impregnation rate)
