Technical Field

[0001] The invention relates to the technical field of vacuum low-temperature frying equipment, in particular to vacuum low-temperature frying equipment capable of de-oiling in a furnace. Background Art

[0002] The existing vacuum low-temperature frying equipment traditionally uses the method of de-oiling outside the furnace. That is to say, after frying in the furnace, it needs to be dragged outside the furnace for de-oiling, that is, put into a de-oiling machine or a spin dryer to remove the oil; when the vacuum is released, when it is lifted out of the oven after frying, some oil will be absorbed inside the product.

[0003] Regarding food hygiene, after frying in the fryer, the food is taken out and placed in the de-oiling tank in the spin dryer for de-oiling, and then taken out and poured into the packaging workshop. This is actually an extra process, which leads to an additional key quality control point. This is more troublesome because if the de-oiling machine may not be cleaned, or after a day's production, it needs to be cleaned from time to time. If it is not cleaned, it is easy to cause the colony count to exceed the standard.
