The difference between cold pressing and hot pressing methods

Cooking oil pressing methods has two kinds: cold pressing and hot pressing methods. Henan Doing Company can provide cold pressing and hot pressing equipment according to your basic requirement. Next, I will tell the difference between cold pressing and hot pressing methods. Keep on reading!

Cold pressing method:

There is one special screw oil presser called cold presser which the oilseed feeding temperature is under 80℃, and without the cooking step before pressing.

The features of cold pressing method:

1. Final oil color is best after cold pressing. If your final oil requirement on color has strict standard, we suggest you consider using cold pressing method.

2. The quality of oilseeds cake is best. Due to no high temperature process involved by cold pressing method, the protein in cakes keep original quality and can not be changed even if after pressing. So the oilseed cakes still have high nutritional value.

Hot pressing method:

When the oil seed feeding temperature into oil press machine is above 80℃, it is called hot pressing method.

Generally, there is one cooking machine before pressing, whose function is mainly to adjust the temperature and water content in oil seeds, increase oilseeds temperature, to meet the requirement by oil presser, and increase final oil yield.

The features of hot pressing method:

1. High oil yield: After cooking then pressing, nearly all the oil in oil seeds will be extracted.

2. Smell best: Due to the cooking machine working with high temperature, the final oil smells and tastes best.

3. Low oil residual: After hot pressing, the residual oil in cakes is smallest.

What is the difference between hydraulic oil press and screw oil press?

Hydraulic oil press and screw oil press are the main kinds of oil press used in cooking oil production industry, and they have their own advantages and disadvantages. If you don't know how to choose them, Henan Glory Company will introduce you the difference of hydraulic oil press and screw oil press, through the advantages and disadvantages. You can choose suitable oil press to use based on your needs.

1. The introduction of hydraulic oil press

Hydraulic oil press uses physical way to extract oil, and the oil quality is better. Hydraulic oil press is easy to operate and cost less, usually used in family or small scale oil extraction production line. The hydraulic oil press is suitable for cold pressing, especially for sesame, peanut, walnut and so on.

(1) Advantages of hydraulic oil press
Compared with ordinary screw oil press, hydraulic oil press is environmental protection and energy saving. There is less noise during operating. It is physical pressing without heating, no addition of any chemical substances. The major advantages of the hydraulic oil press is that the pressure of the equipment is hydrostatic, and the mechanical friction of the oil is very small, so the oil is very clean and can be consumed directly without any treatment.

(2) Disadvantages of hydraulic oil press
Different from screw oil press, the hydraulic oil press is a closed hydraulic system, if only part of the leakage of oil will make the whole machine useless. Oil yield rate is relatively low, with a single function and low automation.

2. The introduction of screw oil press

Different from hydraulic oil press, the screw oil press presses the oil by continuously pushing the screw shaft forward and squeezing the material. Henan Glory Company provide three types of screw oil press: single screw oil press, screw oil press with automatic temperature control system and screw oil press equipped with vacuum filtration system and automatic temperature control system. Specially, screw oil press equipped with vacuum filtration system and automatic temperature control system is very popular among the small investors. The oil quality is clear and pure with less foam and impurities after pressing.

(1) Advantages of screw oil press
As the screw oil press goes through 3-4 times of squeezing, the oil yield is higher than that of a hydraulic oil press with a single squeeze. And because of the simple mechanical structure of the left and right screw presses, it’s more durable and stable. It also has different model for different processing capacity. Screw oil press is reasonably designed with advanced performance and is suitable for various oil seeds pressing, such as soybean, peanut, cottonseed, sunflower seeds and so on. It can be pressed directly, saving time and costs. The invest cost for the screw oil press is less and the processing capacity is high.

(2) Disadvantages of screw oil press
While screw oil press produces high temperature during work, it will It destroys the nutrients in the oil. The oil has a black appearance and high phospholipid contact. It is necessary to equip a centrifugal filter for fine filtration.

The above is Henan Glory company's introduction of the advantages and disadvantages of hydraulic oil press and screw oil press to make you more aware of their differences and make better choices. We hope that it can be helpful for you. Please feel free to leave a message on our website if you still have any questions.

How many machines are needed in a small-scale peanut oil mill plant?

 The peanut oil mill plant is an essential sector, particularly in regions where peanuts are a staple crop. For entrepreneurs looking to start a small-scale peanut oil mill plant, understanding the machinery requirements is crucial for ensuring efficiency and productivity. This article takes an in-depth look at the number and types of machines are needed in a small-scale peanut oil mill plant.

1.Peanut Shelling Machine:

Peanuts need to be shelled before oil extraction. Shelling can not only increase the production capacity of peanut oil mill machine and improve the efficiency of oil extraction, but also reduce the wear of peanut oil mill machine. Peanut shelling machine is a commonly used machine in the peanut oil mill process.

2.Peanut Cleaning Machine:

Peanut cleaning machine is used to remove impurities such as leaves, sticks, stones, sand, dirt, spoiled seeds and metal contaminants. Examples include magnetic selector, de-stonner and vibrating cleaning sieve. Peanut cleaning avoids damage to other peanut oil mill machines.

3.Peanut Crushing & Flaking Machine:

Peanuts need to be crushed before oil extraction because of their large size. In addition, since peanuts have a high oil content, peanut oil flaking machine may not be required if the yield is small. The function of the peanut crushing and flaking machine are to increase the contact area between the peanuts and the peanut oil press machine, which is more conducive to the oil press.

4.Peanut Roasting Machine:

While not all peanut oil mill plants roast peanuts before oil extraction, roasting can enhance the peanut oil's flavor and quality. Peanut roasting machine ensures uniform heating and improves the taste of the final oil product.

5.Peanut Oil Press Machine:

The heart of the peanut oil mill machine is the peanut oil press machine, which presses the oil out of the peanut through mechanical force. For a small-scale peanut oil mill plant, a screw peanut oil press machine is typically used due to its efficiency and moderate cost. Henan Glory Company is your best choice for this. In addition to screw peanut oil press machine, we also have integrated peanut oil press machine. Integrated peanut oil press machine has the unique features, such as less dimension, high oil extraction rate, low energy consumption and high automatic degree.

6.Peanut Oil Clarification and Filtration Machine:

After oil extraction, the crude peanut oil contains impurities that need to be removed. An peanut oil clarification machine uses centrifugal force to separate solid particles from the liquid, improving the peanut oil's clarity. Post-clarification, a fine filtration process is necessary to meet standards for consumer-grade peanut oil. Plate and frame filtration machine is commonly used for this purpose. Finally, the peanut oil is bottled and stored and can be sold.

In conclusion, the above is just a basic setup for a small-scale peanut oil mill plant. The peanut oil mill machines needed may vary depending on specific requirements and production capacity.
