Granular fertilizer slow-release coloring device

Abstract

The invention relates to a granular fertilizer slow-release coloring device. The device comprises a quantitative feeder, a solution preparation device, a fluid flowmeter, a rotating drum and a finished product stock bin. The quantitative feeder is connected with a feeding port of the rotating drum, the solution preparation device is connected into the rotating drum through the fluid flowmeter, and a discharging port of the rotating drum is connected with the finished product stock bin. A fertilizer coloring agent comprises the components in parts by weight: 3-5 parts of a dye, 12-20 parts of a film forming agent, 1-3 parts of a dispersant, 130-160 parts of water, and 0-2 parts of an emulsifier. A fertilizer processed by the granular fertilizer slow-release coloring device has bright surface luster and regular particles, enables the release speed of quick-acting nutrients to be slowed down, and enables the granular fertilizer to be high-effectively prevented from caking.

Description

[0001] This application is a divisional application of the 201210339554.5 patent application. technical field

[0002] The invention relates to a coloring agent for fertilizer and a method and device for sustained-release coloring of granular fertilizer, belonging to the technical field of fertilizer production. Background technique
