Tableting

Biopharmaceutical Tableting. Tableting is the process of forming pharmaceuticals into tablets. The tablet-pressing process requires that all ingredients be dry, powdered, and of uniform grain size. It is critical that the amount of active ingredient is equal in each tablet. Compressed tablets require great pressure to compact the material. If a homogenous mix cannot be obtained with simple mixing, the ingredients must be granulated. Granulation is the process of collecting particles together by creating bonds between them. Two common processes are wet granulation and dry granulation. Wet granulation uses a liquid binder to bond the powder mixture which is subsequently milled to form granules. Dry granulation, which requires a drug with cohesive properties, is conducted on a press, and often requires repeated compaction steps to get the proper result. After granulation the tablets are formed in a tablet press.

Tank Breather

Tank Breathers. These are components, normally installed into a threaded port that breaches the tank wall, that allow air to pass in and out of the tank to compensate for changes in the tank’s internal pressure. Breathers are usually filtered and partly self cleaning. When air enters through the breather, contaminant particles are trapped at the surface of the breather’s filter. When air is expelled through the breather, it forces the contaminants back into the environment. When the air is expelled from the container, the pleated filter cleans itself by releasing dirt back into the atmosphere. When breathers are no longer performing efficiently, they can be easily replaced.

Technology

Process Technology. A broad concept that deals with the knowledge and implementation of the tools, skills, and methods used to design, fabricate, operate, and maintain processing systems, such as chemical and material manufacturing processes. Process technology and technologists are found in a wide range of industries, such as the petrochemical, mineral processing, material, food, pharmaceutical, and biotechnological industries.

Terminal Blocks

Control Panel Terminal Blocks. These are any of several styles of terminal blocks designed to mount on DIN rails on control panels manufactured to DIN standards.

Thin Film Evaporators

Thin-Film Evaporators. A thin-film evaporator has two major components: a heated body and a rotor. Process fluid enters above the heated zone, and is distributed evenly over the inner surface of the body wall. Rotor blades spread the product over the entire heated wall, and generate turbulent flow in the thin liquid layer. The product spirals down the wall while turbulence, developed by the rotor, generates optimal heat flux that evaporates volatile components. The resulting vapors flow upward into a centrifugal separator, which returns entrained droplets back to the heating zone. Clean vapors pass through the vapor outlet ready for condensing or further processing. The concentrated liquid stream leaves the evaporator through its bottom conical outlet.

Thin-Film Evaporators

Thin-Film Evaporators. Film Type Evaporation involves generation of a thin product film over the heat transfer surface to promote minimal resistance to heat transfer. The material is heated until the lower boiling component starts to evaporate. These vapors are then liquefied on the cold tubes of a condenser. The device usually consists of a jacketed cylindrical heating section, a top vapor section with an entrainment separator, a top cover with mechanical seal housing and roller bearings, and a bottom conical section housing the lower bearing. An internally revolving rotor equipped with either wipers or blades provides internal distribution and rapid transport of the product film over the heated area. Evaporation often takes place under vacuum. The disengaged vapors are either condensed externally in a tubular/spiral condenser, or led to a column, or to another downstream process.

Top Unloading

Top Unloading Centrifuges. These centrifuges, of several different types, are characterised by providing access to the processed material through a door or bulkhead at the top of the unit. Usually found in medical or laboratory environments

Transmitter

Pressure Transmitter: A device, also known as a pressure transducer, used to electronically convert the pressure of a gas or liquid in a vessel or pipe to an electronic signal. The electronic signal is then measured by an electronic sensor, or read by a computer to display, trend and/or alarm the operator.

Transmitter

Weight Transmitter. An electronic device that processes the low voltage electrical output from mechanically deforming load cells, amplifies that signal, and uses it to operate an integrated digital or analog readout, or to control another device. A load cell is a transducer which converts force into a measurable electrical output. Although there are many varieties of load cells, strain gauge based load cells are the most commonly used type. They offer accuracies from .03% to .25%full scale, and are suitable for most industrial applications.

Transmitter for Chemical Process

Chemical Process Pressure Transmitters. These transmitters operate like all other pressure transmitters. They sense the pressure level and convert that input to an electrical signal that can be used to operate a readout or other device. The characteristic that differentiates them from other transmitters is the requirement to operate in processing systems that handle chemicals such as, hydrocarbons, petrochemicals, solvents, organic and inorganic acids, halogens, salts, caustics, etc. Many of these devices are designed to handle a broad range of chemicals, but must be selected for the specific process.

Transmitter for Chilled Water/Glycol

Chilled Water/Glycol Pressure Transmitters. These transmitters operate like all other pressure transmitters. They sense the pressure level and convert that input to an electrical signal that can be used to operate a readout or other device. The characteristic that differentiates them from other transmitters is the requirement to operate in chilled water air conditioning systems that must cool below the freezing temperature of water. The transmitter components that interface with the water/glycol media are usually made of copper.
