Low-temperature deep frying device and method for deep frying food

Abstract

The invention provides a low-temperature deep frying device and a method for deep frying food to be deep fried. The low-temperature deep frying device comprises a deep frying groove, a material inlet / outlet door, an oil inlet / outlet, a heating tube arranged in the deep drying groove, a vacuum device for making the interior of the deep frying groove reach a vacuum state, a deep frying main air cylinder for adjusting the deep frying position, a material inlet / outlet door air cylinder a for driving the material inlet / outlet door to descend or ascend, a material inlet / outlet door air cylinder b for driving the material inlet / outlet door to be opened or closed, an oil level meter for detecting the height of the oil level, a temperature gauge for detecting the oil temperature, and an electromagnetic valve used for receiving an oil temperature signal and controlling the deep frying main air cylinder, the material inlet / outlet door air cylinder a and the material inlet / outlet door air cylinder b, wherein the material inlet / outlet door and the oil inlet / outlet are communicated with the deep frying groove. According to the low-temperature deep frying device, the amount of oil injected into the deep frying groove and the temperature of the oil in the deep frying groove can be known through the oil level meter and the temperature gauge; through the deep frying main air cylinder, the position of a material inlet basket can be adjusted so that articles, to be deep fried, in the material inlet basket can make full contact with the oil.

Description

technical field [0001] The invention relates to a frying device, in particular to a low-temperature frying device and a method for frying fried food. Background technique [0002] At present, the existing frying equipment is composed of circular dehydration kettle, oil storage tank, vacuum pump, condenser, transmission motor, circulating oil pump, filter and heating, and the circular dehydration kettle and oil storage tank are integrated. , during the production process, put the processed products into the dehydration basket, and then confirm the production conditions before feeding, close the vent valve, turn on the vacuum pump to make the vacuum in the kettle reach below -0.092mpa, then close the oil discharge valve, and turn on the circulating oil pump , put the oil into the kettle for frying. During the frying process, the water evaporated from the food first passes through the condenser. When the oil is circulated and heated, the oil in the dehydration kettle flows into...

AI Technical Summary

Problems solved by technology

[0004] 1. In the production process, semi-automatic manual operation not only increases the workload of workers but also cannot guarantee the stability of products

[0005] 2. Due to the limited conditions of the circular dehydration kettle, the production capacity is low each time, and the vacuum area of ​​the upper part is small during the frying process, which also affects the dehydration speed of the product

[0006] 3. The circular dehydration kettle adopts a circulation heating method, and the residue in the oil is continuously circulated in the pipeline and the kettle, which affects the service life of the oil

[0007] 4. Round dehydration kettles can only use round baskets, which limits the types of product processing

[0008] 5. During the production process of the circular dehydration kettle, the products can only be processed in a fixed position in the kettle, and the processing position in the kettle cannot be adjusted according to different products and different requirements.
