Compared with the old equipment, the economic benefits of the automatic oil press are very considerable. Disadvantages of traditional oil pressing methods: primitive workshop, simple equipment, awkward operation, large area, high energy consumption, low oil yield, and poor sanitary conditions.
Compared with the old-fashioned equipment, the normal oil output rate can be 4-6% higher, and every 100 catties of peanuts processed can produce 4-6 catties more oil on average, and the annual economic benefits are very considerable.
When the automatic oil press is running, the processed oil enters the press chamber from the hopper. The raw material is continuously pushed inward by the squeezing screw for squeezing. Because the material embryo is in motion in the press chamber of the oil press, under the condition of high pressure in the press chamber, a great frictional resistance is generated between the material embryo and the snail, and the material embryo and the press chamber. It can cause friction between the micro-materials of the embryonic material and cause relative movement.
On the other hand, because the diameter of the root circle of the snail is gradually increased and the pitch is gradually reduced, when the snail is rotated, the thread-strengthened blank can be pushed forward and turned outward, and it is close to the screw thread at the same time. The surface material layer also rotates with the press shaft.
In this way, each embryo particle in the press chamber does not move at the same speed and in the same direction, but there is also relative movement between the particles. The heat generated by friction meets the heat required for the operation of the oil extraction process, which helps to promote the thermal denaturation of the protein in the raw material, destroys the colloid, increases the plasticity, and also reduces the viscosity of some oils, which is easy to precipitate. The oil output rate of the oil press is improved, so that the oil in the material is squeezed out and flows out from the gaps in the circular row and the gap in the row.
The electric power is reduced by 40% for the same output. Calculated by saving 6 kilowatt-hours of electricity per hour, the daily production can save 30 yuan in electricity bills. The same output can save labor by 60%, and 1 to 2 people can organize production, which can save about 40 yuan in labor cost per day. The machine is versatile and can squeeze more than 20 kinds of oil crops such as peanuts, sesame, rapeseed, cottonseed and soybeans. Multi-stage squeezing, squeezing clean at once. Vacuum filter residual inspection to ensure the purity of the oil and meet the sanitary and quarantine standards. The oil workshop only needs 10-20 square meters to meet the needs.
