The Importance Of Flow Control In Chocolate Production

Dosing system with automated pump dosing Have you ever thought about how you can further optimize your process by automating the dosing process of ingredients – such as flavorings – into the production line? We often see that chocolate manufacturers, or in fact the entire confectionery industry, still use scales to dose additives into the process. Whereas you can automate this by using a dosing system with flow meters. The latter method has several advantages: Advantages of dosing system with flow controller Accurate dosing of liquid ingredients; this allows you to make efficient use of the raw materials, resulting in

Top 10 Questions About Liquid Dosing

Almost every day you encounter products whose production process involves liquid dosing: when you eat sweets or a piece of chocolate, when you do the laundry or put on some nice perfume. There are countless other examples… Not only is liquid dosing used in the food industry to add fragrances and flavorings, it’s also used to add dyes to detergent and other household products. Another industry where dosing plays an important role is the petrochemical industry, where it’s used to dose additives (like catalysts). When do you need flow meters to dose additives, fragrances and flavorings? When do you need

Humidification of Fuel Cells

Inside the engine of your car, gasoline reacts directly with oxygen from the air to cause combustion which enables your car to drive. This is the conventional way. Chemical energy is converted into useful mechanical energy. An alternative for this is combustion in an indirect way: a more clean and promising manner using a fuel cell. Oxygen and fuel, such as hydrogen, are fed to each side of the fuel cell, to electromagnetically react inside the cell forming water. As a result, electrons flow through an external circuit powering an electric motor. The chemical energy from the fuel is converted

Precise Liquefied Gas Dosing

Our customers have many applications with chemical reactions that are conducted at high pressures. These applications frequently require precise gas dosing. You can replace organic solvents with more effective alternatives, like liquefied gases. What is Liquefied Gas? It is a gas at atmospheric pressure and room temperature turned into a liquid by cooling or compression. An example of this is liquefied carbon dioxide (CO2) which is an excellent extraction solvent for non-polar chemical compounds. There are obstacles when using liquefied gas, such as difficulty in handling these liquid/gas substances and lack of dosing precision. Bronkhorst has taken note of these

A Low Temperature, Safe, and Effective Way to Sterilize Reusable Medical Devices and Equipment

Steam is by far the most common method of medical sterilization used in the U.S today. High temperatures produced by steam are not compatible with all materials and it has other disadvantages. The most prominent low temperature sterilization method currently used is ethylene oxide. EO is a relatively dangerous and toxic material. Vaporized Hydrogen Peroxide: H2O2 has many advantages including low toxicity, low temperature, and relatively good material compatibility. There are several methods in use today this article discusses HPV or hydrogen peroxide vaporization. Using A Controlled Evaporation Mixer To Deliver The Vaporized Hydrogen Peroxide A Controlled Evaporative Mixer or

What is a Controlled Evaporation Mixer (CEM)?

Liquid Delivery System with a Controlled Evaporation Mixer We have many customers that have applications where two components must be mixed. Traditionally, bubbler systems or Vapor Source Controllers have been used when dealing with vapor. These devices have their shortcomings, for example they have been proven to not be able to handle large quantities of liquid with a low vapor pressure. Furthermore, they can’t provide vapor from a mixture of liquids with different vapor pressures. Our partners at Bronkhorst have worked hard to develop a system that has Mass Flow Control of Vapors. This system is our Controlled Evaporation Mixer

Benefits Of Using A Controlled Evaporation vs. a Bubbler

Vapors are normally created using a bubbler system. There are many household items that can be used to create a bubbler systems, but an advanced bubbler will cost thousands of dollars. Bubbler Systems still have their advantages when vaporizing very corrosive fluids. These systems can be used with corrosion resistant tubing from the liquid source to the customer process. While it has this advantage, it also has a list of disadvantages compared to the Controlled Evaporation Mixer. What is a Controlled Evaporation  Mixer System? The CEM System designed by Bronkhorst is a Liquid delivery system that can be applied to

CEM: Liquid Delivery System with Vapor Control

Liquid Delivery System with Vapor Control Introduction: In a number of processes two or more components must be mixed together. In instances where it comprises a vapor of a liquid in a carrier gas, traditional Bubbler Systems and the more recent Vapor Source Controllers have been used. These devices, however, can often not handle sufficient quantities of liquid with a low vapor pressure, or perform in an imperfect way. Moreover, they cannot instantaneously provide vapor of a mixture of liquids with different vapor pressures. Bronkhorst has therefore developed a unique patented system to realize Mass Flow Control of Vapors with

Space Suit Testing

The National Aeronautics and Space Administration (NASA) recently redesigned the system used to test the new space suit Portable Life Support System (PLSS) that is under development. In order to test the PLSS a simulated human metabolic load must be applied to the various sub-systems and so NASA needed to simulate the human production of CO2 and water vapor with its associated heat load. Working closely with NASA engineers to fully understand the application requirements, Bronkhorst learned that accurate, stable control of water vapor was critical to efficient and repeatable testing and therefore successful development of the PLSS. The recommended Bronkhorst
