Description

A tea seed oil pressing device

technical field

The invention belongs to the technical field of tea seed oil production equipment, and particularly relates to a tea seed oil pressing device.

Background technique

Tea seed oil is obtained from the seeds of the tea tree. The production process of tea seed oil can be divided into: screening, drying, shelling, heating and tempering, oil extraction, and filtration. The whole process is a physical method, so it is a real pure natural green edible oil. Generally, an oil press is used to extract oil from tea seed kernels. In order to improve automation, a suction machine is generally used for feeding, and a filter device is used to make the tea seed oil clearer. The filter on the existing suction machine is easy to be blocked. And it is not easy to clean, and it needs to be disassembled to clean up, which is cumbersome, and the filter device generally uses the filter screen to filter directly, and the oil residue generated by filtration is easy to block the filter screen, thus affecting the filtering effect, so the existing filter device generally uses a push plate. Push the oil residue on the filter screen away to ensure the filtering effect of the tea seed oil. However, the oil residue pushed away by the push plate still contains a lot of oil. Pushing it away directly will lead to the filtration of the tea seed oil in the oil residue. rate is lower.
