We represent the interests of three stakeholder groups with a common commitment to promoting food safety and the public health — regulatory sanitarians, equipment fabricators and processors.http://www.3-a.org

It was founded in 1880. The association develops technical guidelines and standards, particularly for pressure vessels. In addition it promotes science and engineering technology and offers professional training. In many areas the Association of German Engineers (VDI) has a similar function as ASME. ASME standards are used in many countries around the world. Knowledge and application of these standards is therefore also important for many companies based in Germany involved in exporting products and services.
The ATEX directive consists of two EU directives describing what equipment and work environment is allowed in an environment with an explosive atmosphere.
Procedure for automated cleaning of process engineering equipment. The definition and aims of CIP can be described as follows: Creating clean interior surfaces in production plants without significant modification of the fixtures required for production runs.
Depending on the water pressure during cleaning a distinction is made between low-pressure cleaning (up to 10 bar) and high-pressure cleaning (25-65 bar).
Cleaned water is compressed to about 4,000 bar and directed onto the material to be cut by a sapphire nozzle. Sand can be optionally added to the water. The cutting jet acts as a thin diamond saw blade. CNC command data guide the cutting jet three-dimensionally over the workpiece.
The combination of the production of ideal mixed goods and the subsequent discharge of the mixed product maximizes the efficiency of the production process.
In many cases this results in undesirable agglomerates which have to be destroyed (deagglomerated) using shear dispersers or smizers (grinding-mixing). Examples of applications: For enhanced development of flavours, spices are separated, liquids distributed very finely, agglutinated materials are pulverised, lecithins are distributed in baking agents, and block grease and block lecithin are broken down.
Primary particles, which have a tendency towards agglomeration or aggregation in smaller grain sizes, can be de-agglomerated by rubbing and crushing. In practice, the deagglomeration takes place by shearing, impact loading and friction (cutting rotors, HighShearBlades, dissolver, milling machines).
amixon® guarantees technically ideal mixing quality, which cannot be improved in practice!
The EHEDG is devoted to the advancement of hygienic design and food engineering. EHEDG is a consortium of equipment manufacturers, food industries, research institutes and public health authorities, founded in 1989 with the aim to promote hygiene during the processing and packing of food products.
An emulsion is a more or less distributed mixture of the two liquids. A surfactant (= emulsifier) can be used to avoid subsequent phase separation. Emulsification can usually only be carried out under the influence of very high shear energies.
It was founded in 1927 and is based in Rockville (Maryland). It defines which raw materials may be used for gaskets, lubricating oils etc. in the production of food and drugs. https://en.wikipedia.org/wiki/Food_and_Drug_Administration
Compliance with the guidelines is intended to ensure long-term product quality and compliance with the requirements of the health authorities.
Distributive mixing means the distribution or adsorption of one component in/ beside another component. Dispersive mixing is random and results from the flowing and swirling of the mix.

. Instant products are usually powders that have to be mixed with further components (usually a cold, warm or hot liquid) in order to obtain a drinkable or eatable product within a very short time.
Ideally this qualification should be carried out by the equipment manufacturer, or the manufacturer should at least provide the associated documents.
The commonly used roughness parameter "Ra" is the arithmetic mean of the deviations from the centre line.
The downward movement of the goods takes place in the centre of the vessel. This type of rearrangement works quick, reliably and without any dead space at different filling levels. On demand choppers can enhance the liquid incorporation and homogeneity. The patented SinConvex® system enables particularly effective mixing and discharge. With SinConvex® mixing tools you achieve technically ideal mixing qualities that cannot be improved any further in practice – within minimum mixing times and
with maximum protection of the products. https://trademarks.justia.com/777/41/sinconvex-77741244.html
e.g. in the pharmaceutical industry, by definition the product-contacting surfaces of the equipment are cleaned without disassembly. Comparable with CIP – Cleaning in Place, although in addition superheated steam (via overpressure or carrier gases) or chemicals are used for sterilisation.
Such areas should be avoided in a mixer. The aim is to initiate total mixing across the whole volume with no dead space, in order to achieve an ideal mix of the whole mixer volume within a short time.
Separation of active ingredients from solvents and suds as well as precipitation suspensions. Usually after agglomeration: gentle drying of baby food, self-service fast food, dried soups, cappuccino Vacuum mixing-drying of special synthetic PP and PE materials after precipitation or stripping Drying of aqueous, alcoholic or other solvent suspensions through vacuum excitation and temperature control.
In a contact dryer, also known as mixing reactor, the goods to be dried are led along a heated surface by a dynamic tool and a shifting of the goods is achieved. The mixing reactor requires no complex treatment of the flue gas and a significantly smaller construction volume. Since contact drying is carried out by technically tight machines, toxic and carcinogenic products can be dried as well.
The operation of the contact-drying is as follows: Due to the contact with the indirectly heated walls, the required temperature for drying of the product is achieved. The process in the mixing reactor can take place under atmospheric conditions as well as at gauge pressure or vacuum.
In the vacuum mixing reactors of the vertical type, as amixon® distributes and manufactures them, the mixing good moves upward on the rotating and fully heated screw band mixing tool and slides downward along the shaft, following the rules of gravity. The heated mixing tool in the mixing reactors offers an optimum heat transfer at its contact surface. The result is a highly effective and time saving drying process.
The mixing reactor requires the consideration of various process parameters that should be determined beforehand in laboratory experiments. The maximum temperature at the contact surface is especially crucial for drying. The wall temperature of the mixing reactor is influenced by the thermal stability of the material to be dried. In addition, the tendency to crusting of products in mixing reactors must be observed. Also, the product can undergo different product phases at the mixer reactor, which should be previously determined in the laboratory through the pilot phase.
The system empties and dries itself completely and seals itself pressure-tight and vacuum-tight. It offers simple control, requires only one linear drive, takes up little in-
stallation space and has a low weight. For the drying process large quantities of warm air can be put into the mixing chamber through the system. Installation positions: horizontal, vertical or inclined.
