Device for preparing liquid spherical particles and method for preparing liquid spherical particles

Abstract

The invention relates to a liquid spherical particle preparation device and a liquid spherical particle preparation method, wherein the liquid spherical particle preparation device includes: a liquid storage bin, a driving mechanism, a piston and a solidification pool; the liquid storage bin includes a bottom bin wall, and the bottom bin The wall is provided with a first opening; the piston is at least partly located in the liquid storage chamber and the end of the piston is provided with a sealing part that can cooperate with the first opening, and the sealing part can move away from or close to the bottom chamber wall in the liquid storage chamber, so as to Make the liquid in the liquid storage bin form droplets between the opening and sealing of the first opening; the driving mechanism is connected with the piston, and is used to drive the sealing part to move away from or close to the bottom wall of the liquid storage bin; the curing pool and the liquid storage bin The opposite arrangement is used for accepting the liquid drop extruded from the first opening and forming a solidified film on the surface of the liquid drop. The liquid spherical particle preparation device can effectively avoid the phenomena of liquid drop tailing and compression deformation, so that the obtained liquid drop has a high degree of sphericity.

Description

Technical field [0001] The present invention relates to a liquid coating technologies, and particularly relates to a liquid preparation of spherical particles spherical particles means and the liquid preparation method. Background technique [0002] As the market demand for healthy and nutritious food continues to increase, the active ingredient of the global food and beverage market demand is also wrapped rapid growth. For the active ingredient into paste granulation process may be employed to achieve wrapping, but for liquid foods drugs, granulation process can not be coated. At present, the commonly used liquid coating technology on the market orifice method, i.e., a liquid flow is applied with a dropper and the like, and to a certain frequency and amplitude is applied to flow droplet liquid droplet vibration means or pulse means so that the jet of solution fracture, liquid droplets into the cured cured to form a predetermined size of the droplets. Although this method enables...

Problems solved by technology

Although this method can achieve liquid coating, it is prone to tailing and poor sphericity, especially for large-volume droplets. Due to the gravity of the solution, the upper droplets continue to move downward during the formation of droplets. Accumulation, resulting in compression and deformation of liquid spherical particles, forming droplets into water droplets, affecting the appearance of the product
