Whereas separators were initially used for separating tissue particles of the fruit out of the press juice or fining agents during the clarification process, decanters are now also used as a substitute for presses. The development of this centrifugal technology has run in parallel with the development of fruit- and vegetable-processing operations. Increasingly demanding requirements in relation to the quality of the final product have necessitated a correspondingly higher level of quality of the technology used. Increases in the size of operations have meant that the capacities of machines and equipment have had to be adjusted. The requirements of environmental protection have become more and more demanding, and this development has led to low-emission and energy-saving technologies.

However, the main aspect for the success of operations has always been the question of economy. Separators and decanters from Huading Separator are appreciated as systems capable of increasing yields during juice extraction and avoiding processing losses.

Coffee is booming in popularity throughout the world. Meeting this escalating demand for new convenience products, in forms such as ready-to-drink beverages, iced mixes and quick-soluble products, results in almost countless commercial opportunities.

Instant coffee is playing an ever more important role these days. The particular boost to the growth of soluble coffee is due mainly to flavored specialties like cappuccino, espresso, vanilla, chocolate or Amaretto.

Modern convenience products of this kind are not successful purely because they are simple to prepare and come in a wide range of flavors. Absolutely consistent quality is just as important. Where enjoyment is such a focus, a process technology which is gentle on the product is of outstanding importance.

Separators and decanters from Huading Separator supports the coffee industry with clarification of weak and thick extract and extract recovery in obtaining the maximum yield from their valuable coffee beans and securing a high standard of quality economically.
Another sphere of application is the production of coffee surrogate and cereal drinks.

━ Clarification of coffee extract
━ Production of instant coffee


Decanters and separators from Huading Separator are widely used in the production of cold- and hot-mix instant teas and ready-to-drink tea products. Following extraction, various clarifying stages ensure that the extracted tea leaves are perfectly dewatered and that all residues are completely removed. The high degree of clarifying efficiency is associated with extremely gentle treatment of the tea extract and maximum product yield.


The increasing popularity of citrus beverages with the consumer together with the importance which food scientists attach to the citrus fruit has led to an impressive development in this market.

Huading Separator has been heavily involved in developing a large number of new processes, for modern methods of processing citrus fruits provide many possibilities for the application of clarifying and separating technology.

━ Alcohol from citrus products
━ Citrus oil dewaxing
━ Production of aromatic water
━ Production of clear lemon juice
━ Production of essential oils
━ Production of juice and concentrate
━ Production of natural cloudy juices
━ Separation of pulp



Huading Separator has taken a further step in the field of brewing beer. Whereas separators and decanters have been used for a long time in the production of beer, the latest process represents a further milestone in filtration technology: the beer separator and membrane are combined, the entire filtration process flows continuously, with maximum yield and a simple method of changing types. The environment is protected and process costs are reduced. Anyhow, disc separators and decanter centrifuges play a key role in the manufacture of beer. In the decisive steps of the brewing process, they ensure economical operation and a high quality of beer.

Beer can be produced on any scale from small home brews, to craft beer micro-breweries, and finally large industrial scale.  However, the brewing process is ultimately very similar on each scale as below:


━ Beer Recovery from Tank Bottoms
━ Clarification of Beer before Kieselguhr Filtration
━ Cold Wort Separation
━ Green Beer Clarification with Addition of
━ Yeast/Tank Bottoms
━ Green Beer Separation
━ Hot Wort Separation
━ Manufacture of Non-Alcoholic Beer
━ Trub Wort Separation
━ Turbidity Adjustment with Separators

In a brewery centrifuge, which may also be called a beer separator or a decanter centrifuge, these same principles are applied to a liquid-wort or beer. The liquid is laden with various types of suspended particulate, including yeast, trub, and hop residue, each with a different density. When a centrifuge spins the liquid within a round bowl, at a given rotation speed, eventually the heavier components of the liquid, notably trub and yeast, because they experience greater centrifugal forces, will move closer to the bowl’s outer wall. Meanwhile, the lightest components, including water and alcohol, will stay closer to the center axis of the rotation bowl. This type of centrifugal separation is aided further by the fact that the circumference of the circle traveled by the liquid closest to the center is much smaller than the one traveled by the particles along the outer wall. This even further reinforces the separation of particles in the liquid according to their density. In terms of physics, the power of the centrifugal forces is governed by an equation called Stokes’ law, and centrifuges in a brewery are constructed to generate truly enormous rotational forces that may be several thousand times the size of the earth’s gravitational forces. See stokes’ law. Such disc beer separator or decanter centrifuge also allow for the draining of the clear, separated liquid from the rotation bowl, while removing the undissolved particles out of the bowl. This is the principle of a functioning centrifuge in practice. Centrifuges in the brewery are employed in several ways. A wort centrifuge can separate hot trub from clear wort even more efficiently than a whirlpool, which is actually a type of low-tech centrifuge. A beer centrifuge employed before packaging can reduce the beer’s turbidity by separating many or most of the yeast cells from the clear beer. This is particularly useful if the beer is to be packaged unfiltered, but the yeast does not flocculate sufficiently to the bottom of the fermenter. It is possible to link the centrifuge to an optical sensor that measures the turbidity of the beer; properly used, this setup can be used to adjust haze or yeast cell counts in the final package. Likewise, a beer separator can remove some of the yeast between the end of primary fermentation and the beginning of secondary fermentation or before lagering. If the brewery uses fining agents, these, too, can be removed via centrifuge. Another favorite location for the use of centrifuges is right before an in-line filter. Because the centrifuge removes the bulk of the particulate, the filter medium can perform its function for much longer intervals before it needs to be serviced. A completely different purpose of a centrifuge is beer reclamation. When excess or spent yeast slurry is purged out of the bottom of a fermenter, the liquid part of the slurry is of course perfectly drinkable beer. Some breweries consider it worthwhile to centrifuge the slurry and introduce the reclaimed beer back into the beer flow. Finally, beer can be centrifuged to remove any residual cold break right before packaging. This eliminates, among other substances, some of the protein-type of materials that are directly and indirectly involved in haze formation as well as beer oxidation.
