Description

TECHNICAL FIELD

[0001] The utility model relates to high viscosity sample homogenization field especially to a kind of multi-functional high-speed multidirectional homogenizer suitable for small volume high viscosity sample. BACKGROUND

[0002] Homogenizer is a kind of equipment for uniformly mixing and dispersing sample. Its working principle mainly relies on the mode of high-speed rotation or ultrasonic oscillation. When sample is placed in container, start homogenizer, and the high-speed rotating part or ultrasonic oscillation in it will generate strong shear force and vortex, which will thoroughly mix, disperse or emulsify sample.

[0003] When dehydroacetic acid of medium-high viscosity sample (cake, sample containing starch or fiber) is extracted, cake particles and extracted aqueous solution need ultrasonic during processing, but ultrasonic cannot fully release dehydroacetic acid wrapped by sample particles, and using high-speed shearing homogenization is prone to emulsification, which is difficult to separate oil and water finally. Sample amount is usually 1-5g, which is less and not convenient to operate in centrifugal tube or test tube. High viscosity sample is prone to form viscous wrapping structure under heating, which is not conducive to extraction or reaction. Sample is usually oscillated by vortex and high-speed shearing. Ultrasonic and oscillation vortex have no way to mix sample for material with large viscosity and containing particles. Shearing head of high-speed shearing equipment is relatively large, not flexible to use, and most of them work in fixed direction. It is not convenient to clean, only has single shearing action, and the range of applicable liquid is relatively narrow.

[0004] Therefore, a multi-functional high-speed multidirectional homogenizer suitable for small volume high viscosity sample is provided. UTILITY MODEL CONTENTS
