Description

Vacuum frying device on the rotating shaft

technical field

The utility model relates to a food vacuum frying equipment technology, in particular to a vacuum frying device with a rotating shaft on top.

Background technique

Vacuum frying some food materials is a new food processing technology gradually developed in the 1970s. Because this technology organically combines frying and dehydration, it shows some very good characteristics. For example: continuous heating, frying, deoiling and other processes in a vacuum environment, because the food is processed in a state of relative anoxic and negative pressure, it can reduce or even avoid oxidation (such as fatty acid spoilage, enzymatic browning, etc.) etc.); in a vacuum state, with oil as the heat transfer medium, the water in the intercellular space of the food material will vaporize and expand rapidly, so that the interstitial space expands, the puffing effect is remarkable, the product is crispy and delicious, and has good rehydration Performance; Vacuum frying is to fry and dehydrate food materials at a lower oil temperature than conventional frying technology, which can effectively reduce the damage of high temperature to food nutrients; deoiling products in a negative pressure state can The oil content of the product is obviously reduced, the oil-saving effect is remarkable, and it is beneficial to the health of the eater. At the same time, the finished food is crisp but not greasy, and has good storability. Therefore, it is widely used in the frying process of food materials in food processing enterprises. In this technical field, there are also various types of vacuum frying equipment for different food processing enterprises to choose from. For a large number of small food processing enterprises, they choose more intermittent single-pot vacuum frying equipment. This equipment has a simple structure, small initial investment, and is easy to use. It is very suitable for one-time investment in processing food materials. Use in large cases. Because the motor that drives the deoiling device to rotate in this equipment is located under the fryer, the rotating shaft extends into the pot from the bottom of the pot, and the shaft seal works under the condition of large temperature changes, which is easy to be worn or damaged, resulting in oil leakage , pollute the motor and the space under the pot. At the same time, it is affected by the narrow space and dirty conditions, which makes the maintenance work more difficult.

Contents of the invention

The purpose of this utility model is to provide a vacuum frying device with a rotating shaft on top, which overcomes the fact that the shaft seal of the deoiling device in the current intermittent single-pot vacuum frying equipment is easily worn or damaged, and the maintenance work is relatively difficult. insufficient.

The utility model is realized through the following technical solutions.

The utility model comprises a fryer, a pot cover, a mesh basket, an electric heater, a vacuum pump, an oil storage tank, a connecting pipe, and a connecting valve. A turntable and a turntable support are arranged in the fryer. Under the action of rotation, two straight rods are symmetrically installed on the outside of the turntable with the central axis of rotation of the turntable as the axis of symmetry. The upper ends of the straight rods are provided with notches; The shaft sealer on the pot cover is connected with the output shaft of the motor, and the other end is equipped with a cross arm. The terminal is connected to the mains through the power cord. In the batch-type single-pot vacuum frying equipment of the prior art, just in order to make the loading and unloading of food, there is a spacious operating space, so the motor and the rotating shaft are arranged under the kettle. In the utility model, the motor is arranged on the top of the pot cover, and the rotating shaft, the cross arm and the straight rod are all arranged on the upper part of the inside of the fryer, but when loading and unloading food, due to The motor, the rotating shaft and the cross arm will always be turned over high with the pot cover, so that there is enough space for the basket to enter and exit the fryer, and the straight rod stands on the outside of the basket. It will hinder the operation of loading and unloading food.

In the utility model, when the net basket is deoiled, it is rotated by the turntable, and the turntable platform does not rotate with the turntable, but only bears the weight of the turntable, net basket and straight rod, so the There is friction between the turntable and the turntable platform, in order to reduce the friction force, balls are installed between the turntable and the turntable platform. The motor adopts frequency conversion speed regulation motor, as long as it is equipped with a frequency conversion controller, the frequency conversion speed regulation can be used for the motor, so that it is not only suitable for products with different oil content, but also more energy-saving. In order to ensure food sanitation and durability, the turntable, turntable bearing platform, straight rod, rotating shaft, cross arm and balls are all made of stainless steel.

Compared with the prior art, the beneficial effects of the utility model are:

The shaft seal is made to work in a state with a small temperature change range, and is not easy to be worn or damaged; at the same time, it provides convenient conditions for maintenance operations on the motor, rotating shaft, shaft seal, etc.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

The utility model is a machine that directly processes food under high temperature conditions. Therefore, the use of materials, selection of parts, production and installation processes, etc. must be strictly carried out in accordance with the standards and specifications of relevant food machinery. Pot cover 2 should be strengthened owing to will additionally bear the weight of motor 14, shaft sealer 13, rotating shaft 12 and cross arm 15. The two ends of the cross arm 15 are not connected to the straight rod 11, but are put into the notch at its upper end horizontally. In order to facilitate the cross arm 15 to align with the above-mentioned notch and put it in before the pot cover 2 is covered, the upper end of the straight rod should be Above the mouth of the pot, the notch should have sufficient depth. The heating of the oil depends on the electric heater 4, and the adjustment of the oil level utilizes the vacuum pump 5 and the venting system to allow the oil to circulate back and forth between the fryer 1 and the oil storage tank 6 through the communication pipe 7 and the communication valve 8, both of which are prior art ,No longer. When the ingredients are fried and the oil level in the fryer 1 drops below the basket 3, the deoiling process can be carried out. At this time, the motor 14 can be started, and the rotating shaft 12 will drive the straight rod 11 through the cross arm 15 to make the turntable 9 rotate on the turntable bearing platform 10. There is no doubt that the basket 3 also rotates synchronously, and the food fried The excess oil with the belt is separated under the action of centrifugal force. After the deoiling process is completed, the pot cover 2 can be opened, and the cross arm 15 will be above the pot mouth of the fryer 1 together with the rotating shaft 12 and the pot cover 2, leaving a very plentiful space for the basket to enter and exit.
