Ⅰ.What are the types of vacuum emulsifying mixer for pharmacy?

Vacuum emulsifying mixers are classified on the basis of various aspects such as:

BASED ON AUTOMATION

Automatic Vacuum Emulsifying Mixer

These mixers are offered with high shearing head that moves with high velocities. These have blades and homogenizer for mixing and emulsification of high viscosity substances respectively.

These mixers are fully capable for executing mixing and emulsification steps without necessary human aid. By using vacuum system, the materials are automatically drawn in machine.

Due to automation, the mixing and dispersion is achieved quickly. Cleaning of these mixers is easy owing to installation of CIP system.

Semi-automatic Vacuum Emulsifying Mixer

These mixers are capable of functioning itself and with operator aid. These materials are poured by human in water and oil pots. The machine performs emulsification itself while materials are removed by humans.

Cleaning and maintenance procedures in these mixers are complicated as these are not offered with CIP and SIP.

BASED ON PRODUCTION SCALE

Laboratory Vacuum Emulsifying Mixer

These mixers are employed in laboratory and small scale pharmacies because of their small size and portability. These are used for blending various chemicals with specific mixing values.

These machines are cost-effective solution for small business because of their affordability and easy installation.

Large Scale Vacuum Emulsifying Mixer

These mixers are equipped with latest technology and are used in mass production of creams, paste and suspensions in chemical, pharmaceutical, and food industry.

The large scale mixers are provided by touch screen automated panel, timers, and recorder. The forces generated in these machines facilitates shearing, mixing and dispersion. They provide large output in short period.

BASED ON DESIGN

Bottom Homogenizer Vacuum Emulsifying Mixer

Here, the homogenizer is located at the bottom of pot. The upper part has scraping stirrer. Impact force is strong in these mixers and materials are quickly emulsified.

Air bubbles are not formed due to direction –top to bottom-of emulsification force. The materials are mixed with help of gravitational force. The price of these equipments is less but it is quite difficult to clean these machines and these usually require CIP systems for cleaning.

Top Homogenizer Vacuum Emulsifying Mixer

These equipments are supplied with top entry homogenizers and these are usually present at the top of cover. The mixers handle variety of materials and are easy to clean due to position of homogenizers. These mixers help to attain uniform and thorough mixing

Fixed Homogenizer Vacuum Emulsifying Mixer

This type of mixer is typically employed in mixing of substances on large scale. In this mixer, the lid is attached to pot body and cannot be separated.

The movement of stirrer brings materials in space between stator and rotor resulting in hydraulic shear which brings about emulsification. These mixers are employed in cosmetic, fertilizer, paper, medicine, and personal hygiene industry.

Ⅱ.What working principle do types of vacuum emulsifying mixers for pharmacy follow?

The basic working principle is same for all types of vacuum emulsifying mixers. Some fundamental steps are penned below for your understanding.

Heating

In first step, water pot and oil pots are heated by electric current or by steam unit.

Sucking

Water and oil are then drawn in by emulsifying pot via soft pipes.

Emulsification

The mixing is carried out by the primary agitator. During this stage, the materials are continuously blended, stirred, mixed, and cut by the rotary vanes resulting in formation of new interface of materials continuously. This process is repeated till particles are of the size of 200nm- 2µm.

The hydraulic pressure and centrifugal force produce impact on particles thousand times per minute resulting in emulsification of raw materials. This resultant mixture is of superior quality and bubble free.

Discharging

The materials settle down at the bottom of emulsifying pot and are extracted through the discharge valve located at the lower part of the machine.

Ⅲ.What are the general applications of types of vacuum emulsifying mixer for pharmacy?

Every mixing function such as emulsifying, suspension and dispersion is performed by vacuum emulsifying mixer. These mixers are essential in almost every industry for carrying out mixing of various pastes and creams.
