Cocoa Butter Press Machine Shipped to Malaysia

Tags : 

On April 25, 2022, a set of HOP40/250 hydraulic cocoa butter press machine was shipped to Pasir Gudang Port, Malaysia. This client is large and award-winning cocoa product manufacturer in the world. SIMEC cocoa butter press was initially purchased by the same client in 2017. It’s still working well so far. However, the client purchased new machine again this year to expand the production of extra-virgin cocoa butter.


Cocoa butter is very important ingredient for single origin chocolate, as it forms the continuous phase of chocolate. It is responsible for the gloss, texture, and typical melting behavior of chocolate.

Cocoa butter is also one of the most popular ingredients in cosmetics. The fatty acids in its composition makes it ideal for soothing dry skin on your hands, feet, elbows, and knees. Cocoa butter itself is a great lip balm.

The coco butter is pressed from the cocoa mass/liquor. Before cocoa liquor pressing, there’re a few steps of pretreatment process which is cocoa bean fermentation, crushing and milling. Good liquor preparation helps to achieve a high pressing result of cocoa butter extraction. SIMEC colloid mill is the key equipment to make high quality cocoa mass/liquor. The cocoa mass/liquor is then pressed into cocoa butter and cocoa cake by SIMEC hydraulic oil press. The melting point of the pure prime pressed cocoa butte ranges from 34℃ to 38 ℃, it melts at body temperature.

Cocoa Liquor Cocoa Butter 

Cocoa liquor itself consists of two components; cocoa butter and cocoa powder. In a cocoa press the ‘solids’ (cocoa powder) and the ‘liquids’ (cocoa butter) are separated by pushing the liquor down against cloth bags in a perforated stainless steel chamber. The cloth bag is designed to let the butter pass through but to keep the ‘solids’ inside the chamber. Separating the cocoa butter from the solids requires an large amount force, about 380 tons provided by SIMEC cocoa butter press machine, then the ‘solids’ come out as hard as a brick, which is referred to as ‘cocoa cake’ and is later grinded into cocoa powder.

The advantage of hydraulic pressing is that it creates no sheer forces on the product and allows for exact control of the volume of cocoa butter pressed out ensuring optimum product quality. As a complete solution for efficient cocoa butter pressing, SIMEC cocoa butter press machine is designed and manufactured to meet the latest global industry requirements. It comes with two pieces of perforated barrels in which the cocoa liquor is pressed into cocoa butter and cocoa cake.


The barrels and all the other cocoa liquor and butter contact parts are made of high quality food grade stainless steel. Patented perforated material barrel is precisely processed by CNC machining, reaching to mirror effect through polishing.

In the cocoa butter presses, the butter is separated from the cake. Butter runs out through holes in the barrels, then drips through the dripping trays into a central butter channel and is collected in the butter vessel.

The properties of the cocoa liquor will influence the behavior of the cocoa butter press, so the pressing cycles are adjustable and flexible. The control system will continuously adjust the power supplied to the main hydraulic ram to optimize pressing performance to the liquor. Robust design, easy setting and operation.

The cocoa butter press machine was packed in a steel case and shipped to Malaysia by sea.

Avocado Oil Plant Shipped to Australia

Tags : 

In mid-May 2022, SIMEC shipped a unit of Extra-Virgin Cold-pressed Avocado Oil production line to one of our Australian clients, who owns a family-operating organic avocado orchard in Southwest region.

The organic avocado fruits in the orchard are classified into several grades, such as 2nd grade and other higher levels. Commonly, the 2nd grade avocado fruits are referred to as unqualified commodity fruits, and its price is much lower than the market approved fruits. Compared with high-grade fruits, this low-grade fruit defined in the commodity market has only a slightly different appearance, but no difference in internal quality and oil content. Thereby, the client decided to use SIMEC cold-pressed technology and equipment to produce extra-virgin edible avocado oil that is thought to be a niche market to grow locally.

2nd Grade Avocado FruitsExtra Virgin Avocado Oil

SIMEC has vast expertise and rich experience in innovative technology of producing extra-virgin avocado oil. We furnish our clients with a cold-pressed avocado oil production line that consists of Avocado Pasting Machine, Hydraulic Oil Press and Avocado Oil Purification Apparatus. The avocado pasting machine integrates peeling, destoning and pulping.


It is suggested to have the avocado flesh pulp gone through malaxing before oil pressing, aiming to enhance oil yield. 380 tons of vertical pressing force endows the SIMEC HOP50/280 hydraulic press with outstanding pressing efficiency. The residual oil rate in the oil cake can be controlled in a very low range. SIMEC HOP oil press is developed for absolute cold-pressing, there is no temperature rising during pressing. The oil press comes with two material barrels as standard. The barrels and other parts in contact with the paste and avocado oil are made of high-quality food-grade stainless steel.


The last but not the least, the crude avocado oil from hydraulic oil press will be purified by SIMEC patented Avocado Oil Purification Apparatus. The apparatus adopts ingenious physical purification design to ensure the consistent quality of extra virgin avocado oil.


In this plant, all parts in contact with raw materials and oil are made of food grade stainless steel. SIMEC team has installed and debugged the avocado oil production line before delivery. We will handover a ready-to-produce plant to our client. All electric motors and elements were customized, catering to the accessible single-phase electricity with 240 Volts and 50 Hertz.

The plant will be shipped to Fremantle sea port on May 22, 2022. The client can produce the extra-virgin cold-pressed avocado oil in the coming harvest season of avocado fruits. The packing photos and parameters are as follows:

Cold-Pressed Avocado Oil Extraction Technology

Tags : 

SIMEC focus on the technology and equipment to produce guacamole and cold-pressed avocado oil.

The avocado fruit is widely regarded as an important fruit for its nutritional values, as it is rich in vital nutrients for the human body. There has recently been an increasing demand in antioxidants, given their beneficial effects on human health. In this respect, avocados contain three of the most important ones, which are vitamins. Avocado fat consists predominantly of mono-unsaturated oleic acid, which has been found to reduce harmful low-density lipoprotein cholesterol, while maintaining beneficial high-density lipoprotein cholesterol, and to perform better than typical low-fat diets.

Although avocado is primarily consumed fresh, a substantial increase in the use of avocado-based products (e.g., guacamole) and oil for cosmetics and culinary purposes also suggest further market growth. In general, an avocado fruit is roughly pear-shaped and more or less elongated. Its weight may range from 60 g to 700 g. The relative amount of pulp varies from 60 to 75% according to the cultivar. The oil content may also vary widely. The main quantity of oil is in the pulp/flesh of the avocado fruit.

 Average-Composition-of-a-Hass-Avocado avocado-and-paste
Average composition of a Hass avocado

Hass avocado has large amount of flesh with a high oil content. Depending on the location of the orchard, the oil content of Hass variety fruit flesh can range from 16-17% in September to 25-30% in April depending on the fruit ripening stage. The kernel/stone contains only about 1% of oil, whereas the skin accounts for less than 4%.

The characteristics of avocado fruits can change depending on multiple variables. Variety, ripeness stage, geographical area, fruit humidity are some of main factors that affect extraction rates and the final quality of avocado oil.

As a leading technology developer, SIMEC leverages its significant experience and technological expertise to develop a novel extraction method to obtain high-quality avocado edible oil, so called cold-pressed extra-virgin avocado oil (CPAO in short) which is not refined and maintains the chemical, organoleptic and flavour profile of the fruit flesh.

 Avocado-Pasting-Machine Roasting-Malaxer Avocado-Oil-Machine

For small scale avocado oil production, avocado oil extraction is generally obtained by peeling and destoning the fruit, mashing the pulp, then malaxing the paste, and pressing the oil. The corresponding equipment required include avocado peeling and destoning machine, pulping machine, malaxer, hydraulic avocado oil press, oil purification apparatus. SIMEC offer all the equipment and complete technology.

For large scale processing plant, centrifuge separation technology is recommended to extract avocado oil in a continuous and efficient mode.

Step One: Fruit washing, destoning, peeling and mash preparation

Avocado fruit washing is performed by immersion and jet showering in order to remove dust from the surface of the fruits. Then a multi-channel avocado pasting machine will separate nut and peel from the pulp, then make the pulp into mash form. The nuts are 100% separated.

Skin separation needs to be calibrated according to the desidered quality, since the proportion of skin into the processed mash may affect the pigment composition of avocado oil. Pigments are important for the intensity of the green colour, its stability and its healthy effects.

Step Two: Avocado mash conditioning and malaxing

The avocado pulp mash with a variable proportion of peel is pumped into a colloid mill for further conditioning. Avocado oil comes in a finely dispersed emulsion inside the cells of the fruit pulp, so the extraction process requires rupturing not only the cell walls, but also the structure of the emulsion. 

Colloid mill has the important effect of chopping cutting very finely the peel for maximum pigment extraction, and cuts the filaments remained in the paste and, at the same time, to minimize the emulsion. The avocado paste can be circulated through return pipes and re-grinded easily to achieve the desired emulsion fineness. Qualified pulp mash is temporarily stored and conditioned in the agitating tank.  

The conditioning process provides the possibility to heat the mash before malaxing with the positive effect of increasing volatile compounds and reducing malaxing time up to 50%.

 stainless-steel-colloid-mill avocado-and-paste

After conditioning, the avocado mash is pumped into malaxing section equipped with multi sets of malaxers (kneading machines). Each malaxing machine consists of a stainless steel tank with a central screw ribbon stirring the mash slowly and continuously at a monitored temperature.

Small oil drops are released during fruit milling, then during malaxing merge into large drops (coalescence phenomena) that can be easily separated by centrifugal extraction.

On average we should consider as optimal a malaxer temperature lower than 50°C and a malaxing time between 30 and 45 min. 10%-20% of hot water is added during malaxing/kneading process. The addition of water processing aids (e.g., enzymes and talcum powder) is acceptable, but no chemical solvents can be used.

Step Three: Oil extraction

The separation of oil from solid and liquid phases is done using a decanter centrifuge that exploits the centripetal acceleration to separate continuously a mixture of particulate solids and liquids with phases having different densities. The avocado pulp mash is separated into oil, vegetation water and solids (exhausted pulp and residual skin).

The oil phase and the water phase are collected separately under the decanter centrifuge. The oil phase is pumped out to a vertical purifier centrifuge, while the water phase is pumped out to a vertical concentrator centrifuge.

 Decanter-Centrifuge Disk-Stack-Centrifuge

Step Four: Oil purification and recovery

The avocado oil flowing from the decanter centrifuge still has a certain amount of water and solids. Vegetation water from the decanter should still contain a small quantity of residual oil. Both liquid phases are sent to vertical centrifuges. A disk stack centrifuge is for final oil purification to remove residual water and solids. A second disk stack centrifuge is used to recover residual oil from the vegetation water flowing from the decanter.

Extra virgin avocado oil extraction should be carried out using only mechanical methods including hydraulic oil press, and decanter centrifuge at low temperatures (<50°C). The cold-pressed extraction method can yield an oil with significantly higher pigment levels, a stronger flavour and, consequentely higher health benefits.

The chemical composition and organoleptic profile of cold-pressed extra virgin avocado oil are reported in the table below.

Odour and tasteThe characteristic avocado flavour and sensory assessment shows at least moderate (above 40 on a 100-point scale) levels of grassy and mushroomy/buttery hints with some smoky notes.
The Hass cultivar gives an avocado oil with grassy and buttery/mushroom-like flavours. Fuerte cultivar that has a more mushroomy flavour and fewer typical avocado flavours.

Malaxing for Avocado Oil Extraction

Tags : 

Ripened avocado fruits are premium for the extraction of extra virgin avocado oil. A peeling & pitting machine will remove peel and pit from avocado fruit, then make the pulp to be paste form.

To improve oil extraction efficiency, a malaxing process is important to condition the avocado paste. Extra virgin avocado oil is smooth and presents emerald green. So a low temperature malaxing process with minimal time is required to reduce oxidation of avocado pulp paste. The malaxer should be constantly monitored for temperature.

SIMEC technology can process many varieties of avocados, such as Criollos, Choquette, Carla, Popenoe, Semil 34, Benny, Hass, Fuerte, Pinkerton and Reed. With regard to the temperature in the malaxer, it should be less than 45℃ taking into account the possibility to add the use of an enzyme process to increase oil yield.

Avocado-Malaxer Roasting-Malaxer 

We produce both large scale malaxing system and small scale malaxer.

In the 2nd week of March 2022, a malaxing machine is ready for shipment to Uganda. This client has started avocado oil production since 2021, using HOP50/280 avocado oil press, avocado pasting machine and oil purification apparatus. To optimize processing technique, he decided to order advanced avocado malaxing machine to replace of manual malaxing. Predictably, both the efficiency and yield of his avocado oil mill will be improved.

The malaxing machine uses thermal oil to heat the pan body, which is evenly and stably heated and has high energy efficiency. The malaxing temperature and stirring speed can be set to meet the requirements of different productions. It’s designed to run in full automatic mode. Since it’s a roasting malaxing process, beside avocado paste malaxing, the machine can also roast oil seeds. It is convenient to use, reliable in action and strong in comprehensive ability.

Tags : 

PRODUCT: Cold-pressed Extra Virgin Avocado Oil.

SUPPLY VOLUME: 1000 liters per month, 50 ml/bottle.

ORIGION: Dar-es-Salaam, Tanzania.

PROCESS TECHNOLOGY: The oil is obtained from avocado fruits, adopting 100% cold press technology by using SIMEC hydraulic oil press.

The cold-pressed extra virgin avocado oil is made from ripe avocado fruits, which contains up to 30% oil (based on fresh weight) in the avocado mesocarp. To have optimal oil quality, avocado fruits used for cold-pressed oil production must have ideally ripeness, minimal rots and other postharvest disorders (such as flesh greying due to long storage).

Cold Pressed Extra Virgin Avocado Oil Composition:

Fatty Acid Content
Monounsaturates (oleic and palmitoleic acids) 76%
Polyunsaturates (linoleic and linolenic acids) 12%
Saturates (palmitic and stearic acids) 12%
Non-lipid Nutrients Content
α-tocopherol 70-190 mg/kg oil
Chlorophylls 11-19 mg/kg oil
Carotenoid (lutein) 0.5-3.3 mg/kg oil
Phytosterols (b-sitosterol being the main sterol present) 2.23-4.48 mg/g oil


Almost 70% of cold-pressed avocado oil consists of heart-healthy oleic acid, a monounsaturated omega-9 fatty acid. Additionally, around 12% of avocado oil is saturated fat and about 13% is polyunsaturated fat.

Based on its fatty acid makeup and the presence of these phytochemicals, extra virgin cold-pressed avocado oil is considered to be a healthful oil. It is highly versatile and easy to incorporate into your diet.

For example, it can be consumed cold, but it’s also a safe and healthy cooking oil because its fatty acids are stable at high heat.


It has been proved the cold-pressed extra virgin avocado oil contains but not limited to the following benefits to our body:

I. Reduces Cholesterol and Improves Heart Health

It has been proven that cold-pressed avocado oil has beneficial effects on heart health, including the reduction of blood pressure and blood cholesterol levels.

What’s more, the oil was found to be the most effective in increasing HDL, the “good” cholesterol. It also may reduce blood triglycerides and LDL cholesterol levels, as well as lower blood pressure.

II. High in Lutein, an Antioxidant That has Benefits for The Eyes

Cold-pressed avocado oil is a relatively good source of lutein, a carotenoid that functions as an antioxidant that is beneficial for eye health.

Eating plenty of lutein may reduce the risk of age-related cataracts and macular degeneration.

Our body doesn’t produce lutein, so we must obtain it from our diet.

III. Help Prevent Gum Disease

Some evidence suggests that avocado unsaponifiables may also help prevent periodontal disease, also called gum disease.

According to a study in bone cells and periodontal tissue, avocado unsaponifiables may block a protein called IL1B.

This protein promotes inflammation and is the main driver of tissue destruction and bone loss in gum disease.

IV. Reduce Symptoms of Arthritis

Numerous studies have found that unsaponifiables in cold-pressed avocado oil, may reduce the pain and stiffness associated with osteoarthritis. It seems to be especially beneficial for people who have hip and knee osteoarthritis.

V. Neutralizes Free Radicals

High levels of free radicals (waste products of metabolism) may contribute to diseases like type 2 diabetes and heart disease.

Antioxidants contained in extra-virgin avocado oil can enter cell mitochondria and decrease the production of harmful free radicals.

VI. Enhances the Absorption of Important Nutrients

Some nutrients need fat to be absorbed by our bodies. Among these are the carotenoid antioxidants, found in many plant foods. However, fruits and vegetables rich in carotenoids are typically low in fat.

It’s found that adding cold-pressed avocado oil when eating vegetables, it can increase the absorption of carotenoid antioxidants up to 17 times.


The benefits of extra virgin avocado oil on the human body are not only reflected in internal use, the external use of avocado oil is also beneficial. The following characteristics make extra virgin avocado oil an important ingredient for cosmetic production:

  • The fatty acids in cold-pressed avocado oil appear to improve symptoms of psoriasis.
  • Extra virgin avocado oil has also been studied for its ability to treat skin injuries. It can improves skin and accelerate wound healing.
  • It can provides deep moisturization for dryness skin, delays skin aging process, prevents and treats acne and reduce dark circles.
  • Avocado oil used on hair caring may helps hair growth, keeps hair shiny and smooth.
  • It may Improve nail health.
