EXTRACT CBD FROM THE HEMP PLANT

Also known as cannabidiol, CBD is one of the numerous compounds found in the hemp plant that is now known to have an array of medicinal benefits. Over the last few years, CBD has become so popular that it is now being extracted, produced and manufactured into a wide range of products, including edibles, CBD oils and even creams.

The most popular form of consumption is CBD oil and it is used to treat a number of illnesses; primarily because of the way it effects the endocannabinoid system (ECS) and doesn’t provide users with a ‘high’ that is illegal in many countries around the world. THC is the cannabinoid best known for providing this ‘high.’ Not only does CBD not get you ‘high,’ but it also helps reduce THC’s psychoactive effects.

What is the CBD Substance?
If you are reading this page, you most probably know what THC is. It (delta-9 tetrahydrocannabinol) is the most active ingredient in cannabis, and until recently, it was by far the best-known. THC is renowned for the mind-altering high it provides to users. In contrast, CBD is not psychoactive, but it does promote positive changes in the body.

The way CBD effects our body is quite different from the modus operandi of THC in the sense that it is not involved in direct stimulation of the CB1 and CB2 receptors. The major impact of CBD is caused on other receptors such as Serotonin, Adenosine, and Vanilloid.

For instance, the stimulation of the TRPV-1 receptor by CBD creates a variety of processes including body temperature, inflammation, and pain perception.

Moreover, CBD is known to cause an inhibition in the functioning of FAAH enzyme that directly acts on the CB1 receptor and enables THC to produce its psychoactive effect. CBD has established global interest among industry specialists and its discovery has prompted medical experts to take a closer look at the benefits of CBD.

CBD Extraction Methods
Various strains of industrial hemp are an popular way to extract CBD. They are grown around the world legally; including in India, China and several countries in Western Europe. One of the most popular industrial hemp strains is Fedora 17 because it has an extremely low THC content which means that any CBD extracted from it has virtually no psychoactive effects. CBD oil made from hemp is legal in almost every country around the world including in all 50 states in the U.S. because of the negligible THC content.

There are four common extraction methods:
━ The CO2 Cannabis Extraction Method
━ The Olive Oil Extraction Method
━ The Dry Ice Extraction Method
━ The Solvent Extraction Method

In the industrial mass production process, ethanol extraction process is the most common CBD extraction method, thanks to its thanks to its high efficiency and low cost. Filtration is a common step in producing cannabis and hemp concentrates. Centrifugation is the most effective and efficient way of separating the extracts from the solid biomass material. The extraction process can be carried out in an upstream vessel in most cases. The goal of filtration is to improve clarity, increase potency, enhance stability and create overall better consumer experience. Highest possible yield of wanted active ingredients and at the same time lowest possible amount of solids and unwanted substances in the extract are the most common demands for the filtration step.

SKIMMING MILK AND WHEY

Skimming milk and whey

Milk skimming process
Raw milk of known fat content, free from air, should be fed to the milk separator at relatively constant temperature and capacity. A change in operating conditions will influence the skimming efficiency. Standardized cream and skimmed milk are the products leaving the separator.
Sediment discharged from the centrifuge during separation may contain bacteria, leucocyte, hair, sand and similar. If the hot milk separator is the first centrifugal clarification step in the dairy, the discharged sediment is not possible to recycle. The best way to dispose it is to sterilize it with steam and dump it.

Whey skimming process
For an efficient separation of fat most of the remaining cheese fines have to be removed before separation. Fines can be taken away by sedimentation in tanks, by filtering or by centrifugal clarification. Whey, free from air and preferably from fines, should be fed to the separator, at relatively constant temperature and capacity. A change in operating conditions will influence the separation efficiency. Whey cream and skimmed whey are the products leaving the separator. Sediment discharged from the centrifuge during separation consists of
residual cheese dust and precipitated whey proteins. The best way to dispose it is to send it back to the farmers.

Separation efficiency
With efficiency for a separator, we normally mean the ability to reduce the fat content in milk. But we can also define the performance in terms of the possibility to produce cream with a consistent and high fat content, or a production with no unintentional stops.
For standardization of milk, fat content in skimmed milk is of less importance because part of the cream is re-mixed to get the proper fat content in the standardized milk. For this reason, you may standardize at a higher capacity than used for skimming.

Product quality
The product quality in a milk separation process is most often measured in terms of free fat and air in the discharged products. The temperature for crystallization and melting of milk fat range from 17-38°C. Therefore, it is important to heat the milk to about 45°C before separation, to be sure not to
damage globules with partly melted fat. Free fat causes two serious faults, sticking and clumping. Rancid flavors may also develop as a result of lipolytic reactions. If the incoming milk contains too much air there will primarily be a problem with cream control and foaming in product tanks. Secondarily, air is the major cause for destruction of fat globule membranes. The membranes may repair themselves again, but the globule is smaller and free fat has occurred. Smaller globules mean more fat in skimmed milk.

PALM OIL PURIFIER

Palm oil purifier

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.

 

Operating principle of palm oil purifier

Separation takes place inside a rotating bowl. The teed is introduced to the rotating centrifuge bowl from the top via a stationary inlet pipe, and is accelerated in the
distributor, before entering the disc stack. The separation of liquid-liquld-solids takes place between the discs, with the oil phase moving through the disc stack to the center and is discharged via a stationary centripetal pump. The water and solids separated from the oil moves out to the periphery, the water is led via channels in the top disc to the paring chamber, where it flows out of the centrifuge via holes in the bowl hood. The solids are collected in the periphery of the bowl, from where it is discharged intermittently. The solids discharge is achieved by a hydraulic system which at preset suitable intervals forces the sliding piston to bend down and thus opening the solids ports at the bowl periphery.

 

 

BAKER’S YEAST SEPARATOR

Baker’s yeast is a natural ingredient that has been used in bread-making and other bakery products for thousands of years. It is made up of colonies of micro-organisms that rapidly reproduce and start the fermentation process that naturally raises dough.

Baker’s yeast is the common name for the strains of yeast commonly used as a leavening agent in baking bread and bakery products, where it converts the fermentable sugars present in the dough into carbon dioxide and ethanol. Baker’s yeast is of the species Saccharomyces cerevisiae, which is the same species (but a different strain) commonly used in alcoholic fermentation, which is called brewer’s yeast. Baker’s yeast is also a single-cell microorganism found on and around the human body.

In the baker’s yeast process, Huading Separator, with its exhaustive expertise and extensive range of products, is able to meet even the most demanding customer’s needs of centrifugal separation when it comes to the efficient production of baker’s yeast. The important thing for Huading Separator is to ensure that each customer is able to obtain the best combination of machine size and process stages for their individual production needs.

Baker’s yeast separator are widely used for:
━ Cream yeast
━ Compressed yeast
━ Active dry yeast
━ Instant yeast
━ Rapid-rise yeast
━ Deactivated yeast

The FNEN series nozzle centrifuges are the disc-type nozzle centrifuge for continuous discharge of solids. The centrifuges are specifically designed for separation different types of yeast as well as other fermentation broths and washing of suspended solids and clarification of liquids containing relatively large amounts of solids. Separation of particles down to 0.5 μm is possible.

The feed containing the liquid and the solids is introduced to the rotating centrifuge bowl from the top via a stationary inlet pipe, and is accelerated in a distributor before entering the disc stack. Separation takes place between the discs. The light phase moves through the disc stack towards the centre of the bowl, and is pumped out under pressure by means of a centripetal pump. The yeast is collected at the bowl periphery and continuously discharged through the nozzles. Filler pieces prevent build-up of the solids between the nozzles.

Starch and Modified Starches

Centrifugal separation is a crucial element for the industrial production of starch. The 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 corn, wheat, potatoes, rice, peas and tapioca. With its integrated process lines for starch extraction Huading Separator occupies the important technological position in this important sector.

Starch production essentially breaks down into three distinct technical processes: classification, washing and concentration of the extracted starch. Huading Separator has the requisite technical expertise and the appropriate equipment for each of these processes. Just how diverse the possible uses of decanters and separators are is reflected in the following summary of the principle raw materials and processes:

STARCH&PROTEIN

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.

LATEX SEPARATOR

Latex Separator for concentration of field latex

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

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.

DECANTER CENTRIFUGE FOR CRUDE PALM OIL PROCESS

Decanter centrifuge for crude palm oil process

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.

Huading Separator supply centrifugal separation solutions for all procedures and processes for recovering palm oil. The continuously operating technology combines extremely robust design with high product yield and excellent oil quality. Huading Separator decanter centrifuge cover the whole throughput range required in the palm oil industry with capacities from 30t to 100 t FFB/h.
