What is Silverson high shear mixer?

What is Silverson high shear mixer?

Silverson High Shear In-Line mixers are supremely efficient and rapid in operation and are capable of reducing mixing times by up to 90%. The action of any Silverson In-Line mixer can be modified with the use of rapidly interchangeable workheads.

What is Silverson mixer?

Silverson Mixer Homogenizers are fast and efficient and are capable of producing a fine droplet or particle size, typically in the range of 2 – 5 microns. This degree of homogenization is suitable for the vast majority of products, such as creams and ointments, lotions, sauces and flavor emulsions.

What is a high shear mixer used for?

A high-shear mixer can be used to create emulsions, suspensions, lyosols (gas dispersed in liquid), and granular products. It is used in the adhesives, chemical, cosmetic, food, pharmaceutical, and plastics industries for emulsification, homogenization, particle size reduction, and dispersion.

What is the working principle of Silverson mixer?

Silverson mixer emulsifiers use high-speed rotors to create turbulence and intense shearing forces. Through the turbulence created by the perforated metal sheets, the liquid passes through fine interstices. Suction from the bottom of the head causes material to circulate through the head.

How does high shear homogenizer work?

High shear homogenizers operate at a high velocity to pull, push and break apart a sample. Thus, they generate substantially smaller particles than some other kinds of homogenizers and are an especially good option for the following applications: Particle Size Reduction/Sub-Micron Homogenization.

What is high shear mixer granulator?

High shear granulation is a shaping process for granulation that has been enhanced for application in the pharmaceutical industry. A binder liquid is fed to the powder particles in a closed container with blending tools and a chopper. Dense granules are formed through the liquid and solid bridges that result.

What is the principle of homogeniser?

The homogenizer principle of operation is a rather simple one: spread the laser energy, typically concentrated at the center of the beam, by scattering the beam so that it overlaps itself multiple times, creating a beam with a larger divergence angle than the original beam, but whose energy is spread more uniformly.

What mixers work with high shear stress?

High shear mixers, also known as high shear reactors (HSRs), rotor-stator mixers, and high shear homogenizers, are used to emulsify, homogenize, disperse, grind and/or dissolve immiscible mixtures with components of the same or different phases.

How do you calculate mixing index?

M=σ20-σ2σ20-σ2r. Given the concentrations of the reference component in each cell, the mixing index can be defined and calculated by the statistical method. Lacey pointed out that this index is related to the number of the cells.

At what speed shear mixer can work?

Ultra-high shear mixers operate at higher tip speeds than conventional rotor/stators, around 11,000 – 18,000 fpm.

How the high-speed mixer granulator operates?

A high-shear granulator or high-shear mixer uses a rotating impeller or high-speed rotor (or both) to create flow and shear. High-shear granulation is an effective way to turn powders into dense granules for tableting or coating. To create the granules, powders are added to the mixing bowl and the bowl is sealed.

What is high-pressure mixer?

High-pressure mixing systems are usually are limited to two solvents, each of which is pumped by a separate pump into the mixer, which is located on the high-pressure side of the pump. The mobile phase mixture is controlled by the relative flow rate of the two pumps.

How does a high pressure homogenizer work?

The major principle of high-pressure homogenization (HPH) relies on abrupt pressure gradient, high turbulence, cavitation as well as strong shearing forces, which are aroused under strong depressurization of highly compressed sludge suspensions (up to 900 bar) (Fig.

How does a 2 stage homogenizer work?

Two-stage homogenization is used primarily to reach optimal homogenization results and to break up fat clusters in products with a high fat content. The formation and break-up of clusters in the second stage is illustrated in Figure 6.3. 3. Disruption of fat globules in first and second stages of homogenization.

How is mixing measured?

Mixing measures quantify the spatial homogeneity or, similarly, inhomogeneity in a (fluid) system initially comprised of multiple distinct regions or species. The exact computation of any measure depends in part on how one distinguishes between different species and on what one means by a homogeneous mixture.
