Product Description
The spiral oil press is mainly used for individual home processing oil presses. This product belongs to the type of spiral oil press, with a large output, simple and convenient. The main product now is the screw oil press. There are also fully automatic oil presses for cold pressing. The fully automatic screw oil press is a technology introduced in Korea more than 10 years ago, which uses vacuum filtration and automatic temperature control function. The product oil quality is good. The taste is fragrant and the oil production rate is still high. For on-site processing in urban areas, it looks more transparent in production and reassures customers. It has great benefits for the development of business. Many regions are now operating according to this model, with considerable profits.
The chamber of a screw oil press is composed of a press cage and a spiral shaft rotating inside the press cage. Its working process is to use the reduction of the spiral lead of the spiral shaft or the gradual increase of the root circle diameter to continuously reduce the volume of the pressing chamber space and generate pressure; The extracted oil is squeezed out from the gaps in the squeezing cage, while the residue is pressed into crumbs and continuously discharged from the end of the squeezing shaft. Generally speaking, the oil production can be divided into 3 stages: the feeding stage, the main oil extraction stage, and the cake making stage.
The screw oil press can press more than 20 types of raw materials such as peanuts, soybeans, rapeseed, cottonseed, sesame, olives, sunflowers, coconuts, cocoa beans, grass seeds, tea seeds, walnuts, and other easily difficult plant oils. During processing, 3 stages of pressing can be used to clean the product in 1 go (except for some cases). The oil extraction process is filtered through negative pressure vacuum filtration or centrifugal filtration, resulting in less residue in the oil and ensuring the purity and hygiene of the oil. At that time, conducting experiments on the fire did not foam or overflow the pot. It can meet the national second level standard and can also extract corn, olives, camellia, etc., providing users with good edible oil.All oil crops can be pressed through a fully automatic screw oil press. Including peanuts, soybean oil sunflowers, rapeseed, walnuts, cottonseed, and so on. Especially peanut oil and sesame oil, which are relatively expensive. There is often counterfeiting and oil extraction in the market, which is detrimental to health. Therefore, on-site processing is more suitable for users who value authenticity. It is currently the main usage mode in urban areas.The screw oil press can adjust the appropriate temperature for different raw materials and has an automatic temperature control system, which is easy to operate and simplifies the complexity of stir frying. The reason why the screw oil press is called fully automatic refers to the fact that there is basically no need for other operations besides feeding, automatic temperature control, vacuum filtration, simple operation, small footprint, and high oil output rate.This machine is mainly used for the heating treatment before pressing of common oils such as peanuts, soybeans, sesame, rapeseed, sunflowers, sesame, and tea seeds.

Screw Sizes and Their Uses
Screws have different sizes and features. This article will discuss screw sizes and their uses. There are two main types: right-handed and left-handed screw shafts. Each screw features a point that drills into the object. Flat tipped screws, on the other hand, need a pre-drilled hole. These screw sizes are determined by the major and minor diameters. To determine which size of screw you need, measure the diameter of the hole and the screw bolt’s thread depth.
The major diameter of a screw shaft
The major diameter of a screw shaft is the distance from the outer edge of the thread on one side to the tip of the other. The minor diameter is the inner smooth part of the screw shaft. The major diameter of a screw is typically between two and sixteen inches. A screw with a pointy tip has a smaller major diameter than one without. In addition, a screw with a larger major diameter will have a wider head and drive.
The thread of a screw is usually characterized by its pitch and angle of engagement. The pitch is the angle formed by the helix of a thread, while the crest forms the surface of the thread corresponding to the major diameter of the screw. The pitch angle is the angle between the gear axis and the pitch surface. Screws without self-locking threads have multiple starts, or helical threads.
The pitch is a crucial component of a screw’s threading system. Pitch is the distance from a given thread point to the corresponding point of the next thread on the same shaft. The pitch line is one element of pitch diameter. The pitch line, or lead, is a crucial dimension for the thread of a screw, as it controls the amount of thread that will advance during a single turn.
The pitch diameter of a screw shaft
When choosing the appropriate screw, it is important to know its pitch diameter and pitch line. The pitch line designates the distance between adjacent thread sides. The pitch diameter is also known as the mean area of the screw shaft. Both of these dimensions are important when choosing the correct screw. A screw with a pitch of 1/8 will have a mechanical advantage of 6.3. For more information, consult an application engineer at Roton.
The pitch diameter of a screw shaft is measured as the distance between the crest and the root of the thread. Threads that are too long or too short will not fit together in an assembly. To measure pitch, use a measuring tool with a metric scale. If the pitch is too small, it will cause the screw to loosen or get stuck. Increasing the pitch will prevent this problem. As a result, screw diameter is critical.
The pitch diameter of a screw shaft is measured from the crest of one thread to the corresponding point on the next thread. Measurement is made from one thread to another, which is then measured using the pitch. Alternatively, the pitch diameter can be approximated by averaging the major and minor diameters. In most cases, the pitch diameter of a screw shaft is equal to the difference between the two.
The thread depth of a screw shaft
Often referred to as the major diameter, the thread depth is the outermost diameter of the screw. To measure the thread depth of a screw, use a steel rule, micrometer, or caliper. In general, the first number in the thread designation indicates the major diameter of the thread. If a section of the screw is worn, the thread depth will be smaller, and vice versa. Therefore, it is good practice to measure the section of the screw that receives the least amount of use.
In screw manufacturing, the thread depth is measured from the crest of the screw to the root. The pitch diameter is halfway between the major and minor diameters. The lead diameter represents the amount of linear distance traveled in one revolution. As the lead increases, the load capacity decreases. This measurement is primarily used in the construction of screws. However, it should not be used for precision machines. The thread depth of a screw shaft is essential for achieving accurate screw installation.
To measure the thread depth of a screw shaft, the manufacturer must first determine how much material the thread is exposed to. If the thread is exposed to side loads, it can cause the nut to wedge. Because the nut will be side loaded, its thread flanks will contact the nut. The less clearance between the nut and the screw, the lower the clearance between the nut and the screw. However, if the thread is centralized, there is no risk of the nut wedgeing.
The lead of a screw shaft
Pitch and lead are two measurements of a screw’s linear distance per turn. They’re often used interchangeably, but their definitions are not the same. The difference between them lies in the axial distance between adjacent threads. For single-start screws, the pitch is equal to the lead, while the lead of a multi-start screw is greater than the pitch. This difference is often referred to as backlash.
There are two ways to calculate the pitch and lead of a screw. For single-start screws, the lead and pitch are equal. Multiple-start screws, on the other hand, have multiple starts. The pitch of a multiple-start screw is the same as its lead, but with two or more threads running the length of the screw shaft. A square-thread screw is a better choice in applications requiring high load-bearing capacity and minimal friction losses.
The PV curve defines the safe operating limits of lead screw assemblies. It describes the inverse relationship between contact surface pressure and sliding velocity. As the load increases, the lead screw assembly must slow down in order to prevent irreversible damage from frictional heat. Furthermore, a lead screw assembly with a polymer nut must reduce rpm as the load increases. The more speed, the lower the load capacity. But, the PV factor must be below the maximum allowed value of the material used to make the screw shaft.
The thread angle of a screw shaft
The angle between the axes of a thread and the helix of a thread is called the thread angle. A unified thread has a 60-degree angle in all directions. Screws can have either a tapped hole or a captive screw. The screw pitch is measured in millimeters (mm) and is usually equal to the screw major diameter. In most cases, the thread angle will be equal to 60-degrees.
Screws with different angles have various degrees of thread. Originally, this was a problem because of the inconsistency in the threading. However, Sellers’s thread was easier to manufacture and was soon adopted as a standard throughout the United States. The United States government began to adopt this thread standard in the mid-1800s, and several influential corporations in the railroad industry endorsed it. The resulting standard is called the United States Standard thread, and it became part of the ASA’s Vol. 1 publication.
There are two types of screw threads: coarse and fine. The latter is easier to tighten and achieves tension at lower torques. On the other hand, the coarse thread is deeper than the fine one, making it easier to apply torque to the screw. The thread angle of a screw shaft will vary from bolt to bolt, but they will both fit in the same screw. This makes it easier to select the correct screw.
The tapped hole (or nut) into which the screw fits
A screw can be re-threaded without having to replace it altogether. The process is different than that of a standard bolt, because it requires threading and tapping. The size of a screw is typically specified by its major and minor diameters, which is the inside distance between threads. The thread pitch, which is the distance between each thread, is also specified. Thread pitch is often expressed in threads per inch.
Screws and bolts have different thread pitches. A coarse thread has fewer threads per inch and a longer distance between threads. It is therefore larger in diameter and longer than the material it is screwed into. A coarse thread is often designated with an “A” or “B” letter. The latter is generally used in smaller-scale metalworking applications. The class of threading is called a “threaded hole” and is designated by a letter.
A tapped hole is often a complication. There is a wide range of variations between the sizes of threaded holes and nut threads, so the tapped hole is a critical dimension in many applications. However, even if you choose a threaded screw that meets the requisite tolerance, there may be a mismatch in the thread pitch. This can prevent the screw from freely rotating.
