Problems solved by technology

[0009] There are two major problems in this process: one, it is very difficult to dry whole rubber seeds
The literature also admits in the summary that it is very difficult to dry rubber seeds, so the investment and energy consumption of this set of process equipment are relatively large, and the production cost of the oil factory is relatively high.
Second, the pressing process has a certain demand for the fiber skeleton of the raw material. After shelling, the fiber content of the pure rubber seed kernel is insufficient, and it is difficult to press. Secondary pressing is required, which also seriously increases the production cost.
Later, the factory closed down soon because the technology was immature and impractical.

Embodiment 1

[0031] Get 300 tons of fresh rubber seeds, which contain 33% water. The rubber seed crushing ratio is 2, the particle diameter after crushing is 1 / 2 of the original size, and the rubber seed kernel is crushed into 2-3 petals. In the first round of drying, the drying hot air temperature is controlled at 240-260°C, and the drying time is 35 minutes. After drying, the water content of the rubber seed particles is 12%, and the temperature is 90°C. Then steaming and frying, the steam pressure of the steaming and frying pan is 0.4MPa, and the steaming and frying time is 20 minutes. After steaming and frying, the water content of the rubber seed raw material is 8%, and the temperature is 110°C. Then enter the 200-type oil press, the steam pressure is 0.4MPa, the temperature of the pressing chamber is 120°C, and the pressing time is 65 seconds. The squeezed oil yield is 16.2%, the oil product is clear, and the acid value is 3.8mgKOH / g.

Embodiment 2

[0033] Get 200 tons of fresh rubber seeds, which contain 35% water. The rubber seed crushing ratio is 2.5, the particle diameter after crushing is 1 / 2.5 of the original size, and the rubber seed kernel is crushed into 3-5 petals. In the first round of drying, the drying hot air temperature is controlled at 230-250°C, and the drying time is 30 minutes. After drying, the water content of the rubber seeds is 11.5%, and the temperature is 95°C. Then steaming and frying, the steam pressure of the steaming and frying pan is 0.4MPa, and the steaming and frying time is 20 minutes. After steaming and frying, the water content of the rubber seed raw material is 7%, and the temperature is 120°C. Then enter the 200-type oil press machine, the steam pressure is 0.4MPa, the temperature of the pressing chamber is 125°C, and the pressing time is 75 seconds. The squeezed oil yield is 15.8%, the oil product is clear, and the acid value is 4.2mgKOH / g.

Abstract

The invention discloses novel technology for squeezing oil from fresh rubber seeds. The technology is characterized in that the fresh rubber seeds are not required to be stacked on a stock dump for a long time but directly crushed, dried, cooked, hardened, tempered and squeezed. The time from incoming of raw materials to obtaining of squeezed rubber seed oil and squeezed rubber seed oil cakes can be shortened to be within 3 hours. The technology can avoid the phenomena of heat generation, germination and mould development caused by the fact that the rubber seed raw materials are stacked on the stock dump for a long time in the prior art, can greatly improve the quality of the obtained rubber seed oil and the obtained rubber seed oil cakes, and can also improve the oil yield and the cake yield.

Description

technical field [0001] The invention relates to a process for extracting oil by pressing fresh rubber seeds. Background technique [0002] Rubber seeds are the seeds of the rubber tree, which are produced in the rubber planting areas of my country, southern Yunnan and Hainan. Rubber seeds are rich in oil and protein, and are an oil resource to be developed. [0003] The processing and utilization of rubber seeds in my country is still in a very extensive and primitive state. Several existing small-scale rubber seed processing plants can only be piled up for a considerable period of time (45-60 days) on the yard after purchasing fresh rubber seeds. After the rubber seeds dry naturally, they can be processed and squeezed. But when the rubber seeds are piled up for a long time and dry naturally, the oil, protein and other nutrients in the rubber seeds are also lost due to heat generation, germination, and mold. It is estimated that during the natural drying process of fresh ...
