Description

Technical Field

[0001] The utility model relates to the technical field of pressed oil purification, in particular to a pressed oil purification unit. Background Art

[0002] A pressed oil purification unit is a set of equipment for physically purifying pressed edible vegetable crude oil, and can purify pressed rapeseed oil, peanut oil, camellia oil, and sesame oil.

[0003] The existing equipment for purifying pressed oil has low automation and poor coherence between processes. For example, after hydrating the crude oil, it is necessary to manually pour the oil material into the sedimentation tank for sedimentation, and then pour the sedimented oil material into the drying tank for dehydration and drying, which greatly reduces the production efficiency. At the same time, when purifying, an electric heating method is used to raise the temperature, which is very easy to cause local coking of the oil. The coked oil will produce benzo[a]pyrene. Therefore, there is an urgent need for a pressed oil purification unit with high automation and a more reasonable heating method. Summary of the Utility Model
