Technical Field

The invention relates to the technical field of tea oil cold pressing processing, in particular to double-helix cold pressing processing equipment for finished tea oil.

Background

The prior tea seed oil adopts different extraction processes according to different camellia seeds. For the drier camellia seeds, special process treatments are generally required, which specifically include: pulverizing, steaming bran, making cake, squeezing oil, etc.; and for camellia seeds with high humidity, the camellia seeds can be directly squeezed by an oil squeezing device. The oil press needs to stably control the proper tea seed conveying speed and pressing speed during pressing. The speed is too high, the tea seeds are not squeezed cleanly, and unnecessary waste and economic loss are caused; the speed is too slow, which affects the production efficiency of squeezing. The existing squeezing process is generally manually operated, and squeezing is judged by depending on experience of operators every time, so that great waste is easily caused, economic loss is large, production efficiency is low, and actual production needs cannot be met.

With the popularization of cold pressing technology, the application of cold pressing machines in oil plants is increasingly widespread. However, the oil press in the prior art has the disadvantages of complex structure, high cost and low production efficiency. In addition, the phenomenon that tea seeds in a feeding auger slip and bleed, the pressure of an oil press is unstable and the like can be caused due to moisture and other reasons in the processing process of the rapeseeds; in addition, the tea oil is often required to be further processed after being cold-pressed, and an integrated cold-pressed tea oil processing device is required.
