The primary function of the stirrer shaft is to transmit torque from the stirrer motor to the impeller. … The stirrer shaft also performs other mechanical functions: it resists the bending forces created by the impeller, it limits any lateral deflections, and it supports the impeller weight.
Beside above, how many types of stirrers are there?
There are two types of Agitators commonly used, 1. Mechanical Agitators, 2. Electronically Controlled Agitators, I’ll demonstrate commonly used Mechanical Agitators.
- Miscible Liquids Blending. …
- Soluble Solid-Liquid Dissolution. …
- Chemical Reaction Facilitation. …
- Insoluble Material Suspension into Liquids. …
- Dispersing Solids into Liquids. …
- Emulsifying Immiscible Liquids.
Subsequently, what is a planetary mixer?
Planetary mixers are more versatile. They are often referred to as “all-purpose” mixers. They can prepare everything from sauces, frosting and mashed potatoes to cookie, pizza and bread doughs. The removable whip, beater and hook attachments allow for much more flexibility in mixing.
What is a propeller mixer?
Propeller mixers are used for mixing liquids in a wide range of viscosities. They are suitable for the formation of low-viscosity emulsions, for dissolving applications and for liquid-phase reactions.
What is a through shaft?
Thru-shaft is exactly what it sounds like: the damper body is skewered by a continuous damper shaft (picture a hot dog that’s longer than the bun). An IFP design, in contrast, is capped on one end: the damper shaft enters one end, but does not continue through the damper body.
What is fermenter design?
Fermenter or bioreactor refers to a device that provides all the basic necessities important for biological product extraction. A fermenter contains different devices that help to maintain the environmental factor inside it which in turn leads to the production of biological products.
What is shaft mixer?
The shaft is simply the piece of material that connects the motor to the impeller. The shaft can vary by diameter and length. The diameter of your shaft depends on the amount of torque required for mixing and the length depends on the size of the impeller.
What is the aspect ratio of a stirred tank bioreactor?
In stirred tank bioreactor (STR), height to diameter aspect ratio is 3:1 or 4:1 while in the case of CSTR, the aspect ratio is maintained more than 1, to ensure high residence time of gas phase, increase the transfer efficiency and to ensure less power input on introduction of gas, uniform power dissipation.
What is the function of a stirrer in a fermenter?
Industrial fermenters
| Feature | Function | Reason |
|---|---|---|
| Stirring paddles | Keeps the mixture inside the fermenter agitated (stirred) | Mixes the microorganisms with the nutrients and keeps the temperature even |
What is the use of tachometer in stirred tank bioreactor?
In all fermenters it is important to monitor the rate of rotation (rpm) of the stirrer shaft. The tachometer used for this purpose may employ electromagnetic induction voltage generation, light sensing, or magnetic force as detection mechanisms (Brodgesell, 1969).
