World-wide demand for starch and vegetable protein products is growing daily and centrifugal separation technology is a critical element for meeting this demand. Industrial success depends on a combination of increased productivity, premium quality and the economical use of resources.
Starch is obtained predominantly from starch-rich plants such as wheat, potatoes, maize, rice, peas and tapioca. Starch is the material in which plants store reserves of energy, it is a polysaccharide consisting of glucose units. Depending on botanical origin, the starch grains, grain-size distribution and molecular composition of the molecules may vary. The principal components of the glucose units on which the physical properties of starch depend are amylose and amylopectin. It is on these components that the starch’s viscosity and gelatinisation characteristics depend. Among the most important technical properties of starch are adhesion, binding, thickening and stabilisation.
Its functional properties can also be subsequently modified by means of mechanical, chemical and thermal processes, yielding tailor-made products for industry. Today, there are some 1000 different starch products used for a variety of applications such as the making of noodles, farinaceous foods, grape sugar, for sizing paper and thickening paints, to cite only a few examples. Apart from its traditional use in the food and paper industries, highly effective developments for, among other things, detergents, cosmetics, pharmaceuticals and biodegradable products are becoming ever more important. The resulting increase in production and the potential for end-product diversification demands ultra-modern production systems. Today Huading Separator continues to supply various centrifugal separation solutions for starch extraction.
Vegetable proteins are among the most important nutritional resources. At the same time the fascinating properties of proteins are constantly opening up new potential applications to industry. To profit from this diversity these valuable substances must be isolated with a high degree of purity so that they are suitable as tailor-made proteins for further processing. On this basis Huading Separator has developed various techniques and is constantly improving existing processes. The outcome is integrated plant systems and process lines which treat renewable raw materials sparingly, are highly automated and consume much less water and energy than was possible in the past.
Latex, also known as natural rubber, is the milky sap of the tropical rubber tree. The main countries cultivating this tree are Asia, Africa and Central America. Latex is still the most important starting material in the production of rubber. Modern life is virtually inconceivable without this raw material, so varied are the items for daily life we make from it. The industry is increasingly relying on special high-speed separators from Huading Separator to obtain latex efficiently.
Natural latex was once commercially produced in the Amazon in great quantities. In recent times, production of natural latex has moved to Malaysia, Indonesia, and other Far Eastern regions. More than 90% of the total world production of natural rubber now comes from Asia, with well over half of that total originating in these countries. Other leading Asian producers include Thailand, India, and Sri Lanka. China and the Philippines both have substantially increased their rubber production as well. This product is especially good for making rubber gloves, condoms, balloons or other molded thin-walled rubber items.
The process is as follows: after the rubber milk has been harvested, collected and transported to the production facilities, it is first stored in large sedimentation tanks to separate off impurities. After a certain settling period, the latex milk is passed to the separator system.
The separators separate the majority of the aqueous phase, the so-called “skim milk”, and other contaminants from the plantation milk. The plantation milk, also known as “field latex”, contains around 30 percent latex. After separation of the skim milk, the latex fraction in the concentrate increases to over 60 percent. Once stabilizing additives have been added, the concentrate is sold as commercially-available latex.
The LXTC400 is a solids-retaining disc-stack separator used for the process of latex concentration. It is specially designed for the tough process environments at modern latex
production facilities today. The LXTC400 latex separator consistently provides a separation efficiency above 90% during the entire operating cycle.

Nozzle separator PAND45 in 3-phase design
Palm oil sludge separation and de-oiling of palm oil mill effluent
The PAND nozzle separator is used for recovery of palm oil from the settling tank underflow in a palm oil mill. This underflow is commonly called sludge water. PAND nozzle palm oil separator is sometimes installed to recover oil from the heavy phase of a three-phase decanter. The decanter has removed most of the oil and there is very little left for the PAND nozzle palm oil separator. The main task is to recover the oil in the third layer. The requested separation duty here is to separate between water and water with some oil containing suspended solids.
Separation is performed in a rotating bowl containing conical discs, where in the space between each disc the actual separation takes place. The liquid feed enters the bowl through a stationary feed pipe into a rotating distributor insert in the center of the bowl and then passes into the disc stack. Solids are continuously discharged through the peripheral nozzles. The nozzles discharge leaves the machine by gravity via an outlet in the frame. Water are forced towards the bowl wall where they are discharged under pressure through the centripetal pump. The concentrated oil is pumped out by a built-in centripetal pump as well. Should the oil and water content in the bowl move outwards, with the risk of oil being ejected together with the solids, water from the overhead balance tank will automatically enter the bowl and push the oil level back to the normal position.
By removing the nozzle holders from the outside and flushing the bowl with water while running at low speed the PAND nozzle separator can be cleaned without dismantling. In this way, machine down-time is reduced to a minimum.
In addition, the PAND nozzle palm oil separator comes with a CIP program. Flushing water is initially introduced into the feed inlet tube when the centrifuge is running at low speed over a few cycles to be followed later by introducing the flushing water into the clarified light phase (recovered oil) outlet through the disc stack when it is running at higher speed.
All liquid-wetted parts are of stainless steel. The frame is made of cast iron except the top part & frame hood which are of stainless steel. As a protection against erosion, the PAND palm oil separator contains several erosion guards and liners.

The PAWT series 3-phase decanter separates the pressed crude oil mixture that comes from the underflow of the main settling tank into an oil phase, a dry solids cake and virtually oil-free wastewater. The oil phase is sent to a purifier, which polishes the palm oil and reliably removes even extremely small contaminants.
The palm oil sludge enters the rotating bowl through a stationary feed tube and is thrown radially outwards into the bowl through feed ports in the conveyor hub. By means of centrifugal force, the solids and liquids are separated from each other in the bowl.
While the solids particles settle to the bowl wall and are discharged by means of a screw conveyor, the cleared liquid phase accumulates above the separated solids phase and is discharged at the opposite end of the bowl. The oil phase and water phase pass to their respective outlets. The light liquid phase (oil) discharged by means of adjustable dip tubes by gravity, and the heavy liquid phase discharged through overflow weirs.
The PAWT series 3-phase decanter centrifuge comes with two motors, which are controlled by two separate VFD. The VFD system optimizes the differential speed without changing belts or pulleys during operation.
The PAWT decanter centrifuge offers the best wear protection. The different zones and elements in a decanter centrifuge need different wear protections. A variety of materials ensure that the operations are able to withstand high temperatures as well as heavy duty and corrosive products.
• To protect the bowl, the inner surface has strips. Bowl outlets are protected with easily replaceable hardfacing bushings.
• To protect the screw conveyor, the flights are protected with sintered tungsten carbide tiles.
• To protect the sludge discharge ports, these ports are protected with erosion resistant bushings.
• To protect the solids casing, the receiving surface has a thick stainless steel plate.

Oil purifier
The palm oil Purifier is widely used for the purification of palm oil. The oil is fed from the oil tank to the purifier where impurities and water are removed. After purification the oil passes to the vacuum dryer, and is finally pumped to the main storage tank via an oil cooler.
The PASB purifier is a solids ejecting disc stack type centrifuge. The rotating bowl is driven by the electric motor via the flat belt or gear worm. With the feed closed, oil is displaced from the bowl by the addition of displacement water and discharge water is added to release the hydraulic closing force, lowering the sliding bowl bottom. After the discharge cycle, a new water seal is established in the bowl and separation continues. Oil is fed into the purifier by using an external pump. The operating water slide and the complete hydraulic system controlling the sludge discharges are inside the bowl. There is no possibility of contamination from external sources.
The separator bowl is designed for partial discharge of separated sludge, which means that there is a minimal loss of oil. The drive system is of belt drive, or the worm and worm wheel.
The feed system is via external pump system. No operating water tank is required as the purifier requires water at high pressure and this is achieved by an external water pump which operates only during the discharge cycle. Discharging have to be made at regular interval of 15 to 20 minutes and each discharge cycle last for a period of several seconds. The discharge system is fully automated with manual override system.

Biodiesel has established itself as an alternative fuel. Oil crises and increasing environmental awareness will accelerate the current boom globally.
The use of alternative fuels is booming. Apart from bioethanol for adding to petrol, this development is due mainly to biodiesel.
There are several reasons for biodiesel’s success: rising world market prices for oil, the high taxation of conventional fuels, and an international environmental policy that specifically promotes fuels from renewable resources. In addition, the quality of biodiesel is now equal to that of conventional diesel.
Biodiesel can be extracted from virtually all vegetable oils. While rape is the most productive plant in the world, soy bean oil or palm oil are extremely important in other regions of the world. Unlike fossil fuels, whose sources are slowly but surely running out, renewable resources guarantee ‘replenishment’ with each harvest.
And irrespective of the oilseed used, all the by-products, such as bruised grain or glycerin, can be used – so ecology and the economy are in perfect harmony.
Centrifugal separators can be used in the following process stages in virtually all of the following:
━ Separation of methyl ester and glycerine/catalyst / soap/methanol
━ Washing of methyl ester
━ Separation of fatty acids from glycerine
━ Separation of salts from glycerine
Thanks to centrifuges of Huading Separator, the technology for the recovery of vegetable oils has made major progress right up to the present day. In order to drastically reduce the consumption of fresh water and therefore the production of effluent we developed many new centrifuges to meet customer’s demand in practice. The intelligent combination of process and engineering know how is the basis for constantly improved oil yields and capacities of the centrifuges of Huading Separator.
Huading Separator supplies separation technology for the recovery of gelatin, blood plasma and blood meal, for edible and inedible rendering processes as well as for the processing of flotation sludge, animal bones or cooking broths. In order to guarantee optimum yields and a high quality of the produced raw fats we provide i.e. complete wet rendering lines for the recovery of edible fats. Those lines are adapted by our process engineers to individual customer requirements and the specific raw materials used. The complete process, from feeding the plant, the removal of any metallic foreign objects and naturally all separation stages right through to the final testing of the purified fat, can be completely automated and is of course CIP-compatible.
Both separators and decanters have been using for fish oil and fish meal processing more than 100 years ago.
