Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a fully automatic low-temperature vacuum frying device. Background technique [0002] Vacuum low-temperature frying (VF for short) refers to putting food in a negative pressure state in a vacuum state, using vegetable oil with strong antioxidant capacity as a heat transfer medium, and the water in the intercellular space of fruits and vegetables will rapidly vaporize and expand, which is the result of loose tissue formation. porous structure. Vacuum frying technology organically combines frying and dehydration. Food processing under relatively anoxic conditions can reduce or even avoid the harm caused by oxidation, and at the same time, it can well preserve the fragrance of the raw materials themselves; Moreover, during the vacuum frying process, the oil is in a state of negative pressure, and the gas dissolved in the oil escapes in large quantities quickly, and the wate...

Problems solved by technology

However, with long-term use and observation, the above-mentioned all-in-one frying and deoiling machine still has shortcomings: when placing the material frame, it is generally operated manually, and it is directly placed on the rotating device of the vacuum frying tank

This is easy to place the deviation, and when the heating tube in the vacuum frying tank is on the side, it is easy to crush the heating tube when the material frame is placed. At the same time, during the high-speed deoiling in the later stage, the deviation of the material frame will easily lead to center instability. being thrown out, causing equipment failure

When frying, the material frame cover of the material frame is usually directly covered on the material frame, and it is easy to be thrown out during high-speed deoiling in the later stage, causing food to overflow and causing equipment failure

Furthermore, the existing vacuum frying device cannot change the frying environment in the vacuum tank according to the requirements of different foods, so that the crispness of the fried food cannot be optimal. The present invention studies on the basis of this problem. with improved
