There are two main methods of peanut oil: pressing method and leaching method. Squeezing and leaching are two different peanut oil production processes. In the voices related to peanut oil safety, it is often heard that the leaching method is harmful to health. In fact, this statement is wrong. No matter which method is produced, peanut oil , Are safe, let’s take a look at these two unused oil-making processes.
What is the main process of peanut oil processing?
The production of peanut oil is roughly divided into three stages: raw material pretreatment, oil extraction, and crude oil (also called crude oil) refining. Squeezing and leaching refer to two different methods of extracting fat from raw materials. The peanut oil on the market comes from these two processes. After a series of processing of raw materials, the oil inside becomes peanut oil and enters the grain and oil market, while the solid residue becomes oil dregs and enters the two fields of plant fertilizer and livestock feed.
What is the specific method of physically squeezing peanut oil?
Pressing is a mechanical method to make oil, which is divided into cold pressing and hot pressing. The conventional step is to let the raw materials go through the preliminary process of impurity removal, crushing, frying (for hot pressing), and then use mechanical pressure to squeeze out the oil in the oil-making raw materials such as peanuts, soybeans, melon seeds, and separate and filter the oil. Afterwards, the crude oil obtained cannot be eaten yet, and a series of refining processes such as decolorization and deacidification must be carried out before it can be put on the shelves. This method originated from traditional oil-making workshops and has a history of thousands of years. This is how the modern industrial civilization used to obtain oils and fats before.
What is the principle of peanut oil leaching method?
The principle of the leaching method is extraction, that is, the use of organic solvents with different solubility properties for the raw materials to separate the relevant components in the raw materials. The specific method is to immerse the oil-making raw materials after pretreatment processes such as screening and crushing in an organic solvent, and the grease in the raw materials will be transferred to the solvent due to dissolution. After the fat is fully dissolved, the solvent must be removed by distillation, and the remaining fat will become the finished peanut oil after refining, just like the pressing method. Of course, the solvents that are evaporated are not sacrificed, but are collected by the corresponding equipment and then cooled back into a liquid state for recycling.
The mobile container house is mainly a house made from the container plate according to the modern house construction model. It has extremely high practicability and flexibility, making it recognized by the general public in the market. Especially in construction sites and field operations, it is widely used in temporary residential houses, and there is no restriction on the living place, the flexibility is high, and its production period is short, and it is convenient to use. So, what are the advantages of a professional mobile container house?
First, the price is low. The container plate building materials used by the mobile container are compared with the traditional building with the same area and space, and it only costs 20% of the cost. Not only has a higher price advantage, but also has a very high practicality. It can meet the most basic housing needs of some people with middle and lower income levels, and the mobile container house can also take the form of collective rental and can be used multiple times, which greatly saves people's housing costs.
Second, strong liquidity. The easy-to-operate mobile container house can be adjusted and installed according to the different environment of the place of use in the form of splicing construction. It only needs to be connected with iron plates, which is conducive to people's transportation and completion of installation and disassembly operations.
Third, the safety factor is high. The mobile container house adopts iron or steel structure instead of plastic and rubber products that contain flammable and corrosive materials with low safety factors. The mobile container house has the advantages of extremely high load-bearing capacity and strong safety precaution coefficient. It can withstand disasters such as earthquakes and storms, and can reduce the degree of damage to the house. It is also often used in temporary shelters after earthquakes and other disasters.
The above are the three major advantages of professional mobile container house. With the continuous development of the construction industry, houses built using container plates are not only conducive to the construction of temporary residences in different places, but also their strong flexibility and mobility can meet people's needs in different environments and different uses. In the future, construction There are broad development prospects in the development of the industry.

We should all know that winter has different effects on many equipment. Therefore, in order to ensure the normal operation of the auger filling machine, the equipment should be maintained in time after use. Well-maintained equipment is more durable than unmaintained equipment, so that the output of the auger filling machine will not be affected by damage.
Because people's demand for beverages is generally higher. In cold weather, you should check whether the machine has accumulated water and icing, causing the switch to fail, whether the lubricating oil bears enough low temperature, and whether the filling head is frozen or blocked. If you encounter this situation, the simple and convenient method is to use warm water to soak. Remember not to use water with too high temperature to avoid damage to the components. The working frequency of the auger filling machine can also adopt the rhythm from slow to fast, and do some pre-heating.
Then carefully check before use to see if the auger filling machine is operating normally, check if the material meets the requirements, and start the machine after everything is normal. When using, try to put it in a relatively closed place with a suitable temperature. If any material overflows, clean it up in time. When adjusting the equipment, the power supply should be cut off in time, and the parts of the equipment after adjustment should be strictly inspected to ensure normal operation. After use, check the machine and the residual materials on the machine should be processed and cleaned in time.
Therefore, in order to reduce the loss of the auger filling machine in winter, it is necessary to take maintenance measures to ensure the normal use of the equipment to prevent accidents.
