The 6YL series single screw soybean oil press produced by Henan Zhongxing is suitable for small edible oil processing plants or small oil mills. This machine has the characteristics of a multi-purpose machine and a wide range of applications. It can be used for the pressing of various edible oils such as peanut oil, rapeseed oil, sunflower oil, and cottonseed oil. In addition, the single-screw soybean oil press also has the advantages of low investment cost, large processing capacity, simple matching, easy maintenance, strong adaptability, and high oil output efficiency.

1. The structure of single spiral soybean oil press:

The single screw soybean oil press is mainly composed of five parts: hopper, gearbox, press chamber, screw press and frame. Among them, screw press is the key to the entire single screw oil press, and its material will affect the quality and service life of the oil press. (Henan zhongxing reminds you: When purchasing, pay attention to the material of the snails pressed by the single-screw oil press.)

2. Working principle of single spiral soybean oil press:

When the oil press is running, the processed oil automatically enters the press chamber from the hopper, and the material embryo is continuously pushed inward by the press screw for pressing. The oil is in motion in the press chamber of the oil press. The pressure in the press chamber is very high. There will be great frictional resistance between the oil, the screw and the press chamber, causing friction between the oil particles to form relative motion. .

4. Product advantages of single spiral soybean oil press:

(1) The single spiral soybean oil press integrates domestic and foreign oil pressing machinery manufacturing processes, all using national standard steel and spare parts, and has the characteristics of compact design, heavy weight and stability, easy installation, durability, and elegant appearance. Its service life is more than three times that of other ordinary oil presses.

(2) Increase the automatic control function of seed frying and pressing chamber heating, change the traditional dry cake grinding heating method, shorten the preparation time, reduce energy consumption and machine wear, and extend the service life of the machine.

(3) All-round squeezing, one machine for multiple purposes. The single spiral soybean oil press can squeeze a variety of oil crops such as peanuts, rapeseed, cottonseed, sunflower, sesame, tea seed and so on.

6. Instructions for use of single spiral soybean oil press:

(1) The single screw soybean oil press should check the lubrication after every 50 hours of work. The oil cup above the reduction box must not be short of oil. The inner bearing of the adjustment screw of the soybean oil press should be filled with butter from the adjustment screw hole every shift. Once, dry grinding is strictly prohibited.

(2) The lubricating parts of the single-screw soybean oil press should prevent dust and other impurities from intruding. The oil quality of the soybean oil press gearbox should be checked once a year. If deterioration is found, all the oil should be replaced.

(3) When the pressing capacity of the soybean oil press decreases and the cake or oil output is abnormal, the screw shaft of the soybean oil press should be drawn out, and the wear of the snails, strips, and cake rings of the soybean oil press should be checked. Worn parts should be replaced in time.

(4) After the end of each shift, the residual cake in the soybean oil press should be removed, and the dust and grease on the surface of the oil press should be wiped off.

(5) When storing for a long time after the end of the production season, a maintenance should be carried out, and the snails, strips, and cake rings of the soybean oil press should be disassembled, washed and re-oiled, and placed in a dry place.

7. Precautions for the single-screw soybean oil press when squeezing oil:

When operating the single-screw soybean oil press to squeeze oil, it is necessary to keep the feed evenly, not too much or too little, or running idling if the feed is cut off. At this time, the single spiral soybean oil press has normal load, stable operation, rhythmic sound, smooth cake output, basically no residue in the low pressure section, and a small amount of oil residue in the high pressure section, but the proportion of residue in the oil is not more than 9%. Soybean oil extraction The temperature in the press chamber can reach 150-200℃, and the green smoke from the cake outlet should be discharged from the smoking pipe through the protective cover. The hot cake squeezed out by the soybean oil press should be spread out in time, and don't rush to pile up or ship, otherwise it will cause spontaneous combustion. When the soybean oil press has a long continuous working time and the temperature of the machine is too high, cooling measures such as electric fan and blower should be adopted.
