#small #cold #press #oil #expeller
Cold pressed oil has pure natural characteristics, avoiding the adverse effects of traditional high temperature oil processing. The natural flavor and color of the oil are retained in the cold-pressed product oil, and the physiological active substances in the oil are completely preserved (vitamin E has anti-aging function, sterols have skin-healthy function and enhance human metabolism function). The original flavor of the cold-pressed oil is the choice of healthy life. But most oils are not suitable for cold pressing. Gossypol toxin in cottonseed oil and aflatoxin in deteriorated oils must be refined before they can be removed.
The raw materials of cold-pressed oil must be carefully selected. Otherwise, because of the different maturity of raw materials and the influence of harmful substances contained in raw materials (such as aflatoxin in mildewed oils), cold-pressed oils can be cold-pressed without frying in a frying pan. The cold pressed oil has good color and light color, but it does not smell fragrant and does not burn. The key is that cold-pressed oil does not foam when frying, and that it does not silt the pot is its advantage. Cold-pressed oil can also be treated by cold press oil expeller, which is convenient and fast, and has high oil yield.
Hot pressing (cooked pressing) is to press oil after frying in a frying pan. Cooked pressing oil is pure and fragrant, especially sesame, which is rich in oil. The disadvantage is that it will foam and silt when frying without treatment, but this problem can be solved by simple treatment. Usually the hot oil press machine will deal with this problem. less

#palm #oil #expeller #machine
Palm oil expeller machine is divided into five steps:
1. Raw material receiving and storage section
Fresh mature ears were collected from the orchard and trucked to the unloading table. Make the ears fall into the cage car freely.
2. Fermentation section
Killing fermentation is the process of cooking oil palm fruit at high temperature for about 60 minutes in the sterilizing equipment of palm oil expeller machine to destroy the lipase in the pulp so as not to increase the content of free fatty acids in the oil. It makes the fruit soft, easy to mechanically thresh, and also conducive to the subsequent peeling of the core, reducing the damage of the kernels.
3. Fruiting section
Oil palm fruit grains account for about 60% of the whole bundle. The purpose of threshing is to separate oil palm fruit from the bundle. The separated oil palm fruit is discharged into the pressing section.
4. Mashing and pressing section
The purpose of mashing and cooking is to tear the epidermis of the fruit, separate the pulp from the pit, and mash the pulp tissue. At the same time, the pulp is softened by heating, and the pulp cell structure is destroyed. The palm fruit is then pressed by a continuous spiral palm oil expeller machine.
5. Crude oil purification section
The crude oil is obtained by pressing. The crude oil is washed and diluted by water, then settled and filtered to remove the fibers from the oil. This is the general operation procedure of the palm oil expeller machine. less

#cottonseed #oil #expeller
Cottonseed oil expeller machine consists of three parts: 1. Main engine. 2 hydraulic system. 3. Electrical control system
1) Hydraulic system adopts a new unloading circuit of high and low pressure double pump. It consists of high and low pressure combined double pump, high pressure manual rotary valve, high pressure relief valve, medium and low pressure relief valve, hydraulic control one-way valve, shock-resistant electric contact pressure gauge, etc. It has the characteristics of compact structure, convenient operation, universal spare parts, low energy consumption, safety and reliability.
2) Working principle of hydraulic system
Start: motor start, high and low pressure double pump output hydraulic oil through high pressure rotary valve 4 return tank.
Pre-pressure; high-pressure rotary valve to the right, high and low pressure hydraulic oil of double pump through high-pressure reversing valve into the upper chamber of the squeezing cylinder, from the beginning of work. Pre-pressing.
Pressing: after preloading. When the pressure rises to a fixed value, the low-pressure relief valve of the pumping station unloads, and the oil is pumped by the high-pressure pump of the double-pump. When the pressure gauge of the electric contact is set to the pressure range, the motor is cut off. When the pressure drops to a fixed value, the motor starts, so repeatedly squeezed to ensure high oil yield.
Pressure relief: After oil squeezing, the high-pressure rotary valve moves to the left position. The output hydraulic oil of the double pump enters the lower chamber of the oil squeezing cylinder through the hydraulic control one-way valve. The pressure of the relief valve is adjusted to 5 Mpa. After the piston rod of the oil cylinder is withdrawn, the high-pressure valve moves to the middle position and the motor is cut off.
The cottonseed oil expeller machine adopts a thick steel plate structure, high-end atmosphere, stable and strong, durable. less

#screw #type #oil #expeller]
1. When the screw type oil expeller is running, the processed oil enters the chamber from the hopper, and the screw turns to push the embryo inward continuously. Because the embryo is in motion in the chamber of the oil press, under the condition of high pressure in the chamber, there is a great friction resistance between the embryo and the screw, the embryo and the chamber, so that the micro-material of the embryo can be produced. Friction causes relative motion.
2. On the other hand, because the diameter of the root circle of the pressing screw increases gradually and the pitch decreases gradually, when the pressing screw rotates, the embryo can move forward and turn outward. At the same time, the material layer near the surface of the pressing screw also rotates along the pressing axis, so that each embryo particle in the pressing chamber does not move at the same speed, in the same direction, but also exists between the particles.
The heat generated by friction meets the necessary heat in the operation of oil pressing technology, which helps to promote the thermal denaturation of protein in the embryo, destroy colloid, increase plasticity, and also reduces the viscous easy to precipitate oil, thus increasing the oil yield of the oil press, making the oil in the material squeezed out, and flowing out from the round row gap and strip row gap.
Guangxin manufacturer has a professional technical service team, providing timely and comprehensive guidance and service for customers. As a strong brand for screw type oil press, Guangxin has been kept on upgrading technology in the past 20 years, which is the promise to users, also a responsibility of Guangxin stuff. Adhering to the goal of "produce the better oil press for making better quality oil" leads Guangxin oil press into the world. less
