The price and cost of walnut oil equipment oil production line.

What does the walnut oil press machine include, what are the walnut oil press steps.

How much does it cost to buy a cheap walnut oil production line.

Walnut oil is vegetable oil, which is pressed from walnut kernels and belongs to edible oil. The edible oils that we often eat in our daily life are soybean oil, rapeseed oil, peanut oil and so on. There is relatively little walnut oil, mainly because walnut kernels are more expensive than other coarse oil grains, which makes walnut oil more expensive. Although walnut oil is expensive, it has high nutritional value and is called “Oriental olive oil”. Good-quality walnuts are walnut oil pressed by an hydraulic oil press. It has a unique taste, pure oil, easy to digest and absorb, and is suitable for children. Moreover, walnut oil promotes retinal development, calcium absorption, etc.

Oil press to prepare walnut oil: two processes of hot pressing and cold pressing. The most used preparation method is cold pressing, and the most used type of oil press is hydraulic oil press. Let me explain why walnut oil is cold pressed with a hydraulic oil press.

The oil press cold pressing method is used for processing in a production environment below 60 degrees Celsius. The technological process is to shell high-quality walnuts to obtain walnut kernels, use an oil press to extract oil, and filter to obtain product walnut oil. The oil yield of cold pressing is about 50% of that of hot pressing, and the nutrients of walnuts are preserved most completely by cold pressing, so the price of many cold pressed walnut oils is nearly half higher than that of hot pressing oil. Cold-pressed oil is not destroyed, so it can be stored for a long time without additives.

Oil press hot pressing is to fry the shelled walnuts with a frying machine first, and then press them with an oil press. The obtained walnut oil has strong flavor, slightly dark color and high yield. Therefore, compared with cold pressing, hot pressing has higher productivity, but the nutritional content is reduced.

Another reason is to recommend the hydraulic oil press, because the pressure point of the hydraulic oil press is larger than that of the screw press, and the pressure is more complete, so the oil content of the walnut kernel is high. If another hydraulic oil press is used, the oil yield will be lower. high. The minimum daily production capacity requirements are most suitable for hydraulic oil presses. If the daily production capacity requirements are large, screw oil presses are recommended. At present, hydraulic or screw oil presses are highly automated and intelligent, easy to operate, and have good effects in all aspects.

When we choose walnut oil, we must start from these aspects: first, look directly with the eyes. General pure natural physical pressed walnut oil is clean and transparent, and its color is light yellow. In addition, after a period of low temperature, there are no crystals and impurities, and it is pure natural walnut oil extracted with an oil press. Then, look at the manufacturer, oil composition, production license number, production date, relevant certification marks, etc. Judging from the outer packaging. Finally look at the price of walnut oil. Universal hydraulic oil presses are not cheap to press pure natural walnut oil. Generally around 6 usd/catties, the price of natural wild walnut oil may be higher. Walnut oil has high utilization value and edible value, so be cautious when buying an oil press, and pay attention to these points when buying walnut oil.
