Vapor and Liquid Flow Control for Aseptic Packaging

One of our customers, a manufacturer of food packaging equipment, was looking for a solution for aseptic packaging and wanted to supply hydrogen peroxide into their aseptic sterilization process for food processing. As a solution, Bronkhorst supplied multiple vapor generating systems consisting of liquid flow controllers, gas flow controllers, and a temperature-controlled mixing and evaporation device.  Food products are often sterilized as a final step in the process. In aseptic sterilization, the foods have been sterilized outside the packaging. This can be done by steam sterilization. After that, the foods are placed in the aseptic packages that have been sterilized previously in a separate

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

Accurate Dosing Of Release Agent

Have you ever seen cars with a nice ‘leather look’ dashboard? One of our customers in the automotive industry manufacturers these ‘skins’ that look like leather. These ‘skins’ are produced by spraying liquid – colored polyurethane – into moulds. To allow an easy skin release from the mould, a release agent must be applied onto the mould surface. The amount of release agent is essential in this respect and must be perfectly dosed as it determines the quality and look & feel of the product. The ‘skin’ will remain adhered to the mould when too little agent is applied, whereas

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

How To Improve Your Gas Chromatography Analysis

What is Gas Chromatography? Gas Chromatography is a commonly used type of Chromatography in analytical chemistry. This is a very effective practice when you need to separate substances of analytical interest. Gas Chromatography uses chromatographic techniques when applying a gas as the mobile phase and a solid or liquid as stationary phases. The principle of Gas Chromatography involves a controlled carrier gas stream that passes through an injector, column, and detector. Then a sample gas is injected for a short period of time, creating a gas sample plug. This is then separated into different gas components across the column. They

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 Dosing? 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

Hydrogen Peroxide Vaporization Model

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
