[0001] The utility model relates to the technical field of French fries processing, in particular to a vacuum fryer for French fries processing. Background Art
[0002] French fries are a common snack in our daily life. In the process of processing French fries, the cut potatoes need to be fried to evaporate the moisture inside the French fries. At the same time, the French fries are fried to make them easier to store and eat. French fries need to be fried using frying equipment.
[0003] In the prior art, in order to improve the frying efficiency of French fries and improve the health of fried foods, a vacuum fryer is usually used to fry French fries. The traditional vacuum fryer mainly consists of three parts: a pot body, a heating device and a vacuum device. The pot body is usually a cylindrical structure with an open top, and the heating device is located at the bottom of the pot body. When in use, the cooking oil in the pot body is first heated to a specified temperature by the heating device, and then the French fries are put in. The pot lid is closed and the air in the pot body is extracted by the vacuum device to generate a negative pressure inside the pot body, thereby lowering the boiling point of the cooking oil and the vaporization temperature of the water inside the French fries. In this way, the French fries can be quickly dehydrated and fried in a low temperature environment. Although the French fries can be fried, in order to save production costs, the cooking oil is usually recycled. The food residues in the cooking oil are fried multiple times, which is prone to produce harmful substances, which is not good for health. Utility Model Content

DETAILED DESCRIPTION
[0022] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.
[0023] Example: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 A vacuum fryer for French fry processing is shown.
[0024] The first embodiment of the present invention refers to Figure 1 A vacuum fryer for French fries processing includes a mounting bracket 1, which provides a mounting and fixing place for other components. The mounting bracket 1 is a double-layer frame structure. A pot body 2 is arranged inside the mounting bracket 1. Edible oil is poured into the pot body 2 for frying French fries. An electric heating wire mesh 4 is arranged inside the pot body 2. The electric heating wire mesh 4 can heat the edible oil. A pot cover 3 is movably arranged at the top opening of the pot body 2. A sealing block 301 is arranged in the middle of the lower surface of the pot cover 3. The sealing block 3 01 can enhance the sealing performance of the pot cover 3 to the pot body 2. The lower end of the air inlet of the vacuum pump 7 passes through the through hole in the middle of the sealing block 301 and extends into the interior of the frying section 201. The outer side of the upper surface of the pot cover 3 is symmetrically provided with a hanging ring 302. The hanging ring 302 is convenient for taking and placing the pot cover 3. An air extraction device is fixedly provided on the upper part of the pot cover 3. The air inlet of the air extraction device is connected to the interior of the pot body 2. The air extraction device is a vacuum pump 7. The vacuum pump 7 extracts the air from the interior of the pot body 2, so that the interior of the pot body 2 is in a negative pressure state. As a preferred embodiment, Figure 2 and Figure 3 As shown, the pot body 2 consists of a frying section 201 for frying French fries and a residue storage section 202 for storing residues. A filter cage 5 for holding French fries and filtering residues is provided inside the frying section 201. The frying section 201 is a conical structure with a large upper end and a small lower end, and the residue storage section 202 is a big belly structure with small upper and lower ends and a large middle part. The frying section 201 is connected to the residue storage section 202, the electric heating wire mesh 4 is located at the lower part of the frying section 201, and a temperature sensor 6 for monitoring the oil temperature is provided inside the frying section 201.
[0025] When frying French fries, the cooking oil in the pot body 2 is heated by the electric heating wire mesh 4 until the temperature sensor 6 detects that the oil temperature has reached a predetermined temperature. Then, the French fries are poured into the filter cage 5, the pot lid 3 is closed, and the air in the pot body 2 is pumped out by the vacuum pump 7, so that the inside of the pot body 2 is in a negative pressure state. Under the negative pressure state, the boiling point of the cooking oil is reduced. At the same time, the vaporization temperature of the water in the French fries is reduced, so that the French fries are quickly dehydrated in a low temperature environment and the frying is completed. In this process, the food residues generated pass through the filter cage 5 and the electric heating wire mesh 4. The holes in the frying section 201 settle downward to the bottom of the frying section 201 and finally enter the interior of the residue storage section 202. According to the principle of thermal expansion and contraction, the density of hot oil is smaller than that of cold oil. When the cooking oil is heated, the heated cooking oil will flow upward. Therefore, the oil temperature in the frying section 201 is higher than the oil temperature in the residue storage section 202. The French fries are fried in the high-temperature oil in the frying section 201, and the residue generated during the frying process falls into the interior of the residue storage section 202. The residue is weakly heated in the residue storage section 202, thereby preventing the residue from being over-fried and producing harmful substances.
[0026] The second embodiment of the present invention refers to Figure 3 and Figure 4 As shown, a retaining ring 9 is fixedly provided on the upper end of the inner wall of the frying section 201, and the filter cage 5 is overlapped with the retaining ring 9 through the outer extension edge 502 provided on the upper part thereof, so as to facilitate the taking and placing of the filter cage 5. After the frying of the French fries is completed, the filter cage 5 can be directly taken out, the fried French fries can be poured out, and the French fries to be fried can be re-added into the filter cage 5 to continue frying. Preferably, the bottom of the filter cage 5 is concave inward to form an inner groove 501.
[0027] During the frying process of French fries, the electric heating wire mesh 4 heats the cooking oil, and the heated cooking oil turns upward. The inner groove 501 can make the French fries in a hollow state at the bottom of the filter cage 5. When the hot oil turns upward, it can directly enter the middle of the filter cage 5 through the inner groove 501, thereby ensuring that the French fries inside and outside the filter cage 5 can be heated evenly, reducing the situation where the French fries outside the filter cage 5 are overheated while the French fries inside are underheated due to uneven heating, thereby improving the frying quality of the French fries.
[0028] After the French fries are fried, in order to quickly separate the cooking oil and residue, Figure 1 and Figure 3 In the third embodiment of the present invention, a valve 8 is provided at the lower opening of the slag storage section 202 .
[0029] After the frying of the French fries is completed, wait for the cooking oil to cool down, and then manually open the valve 8. The residue inside the residue storage section 202 will flow out through the opening at the bottom of the residue storage section 202 first. After the residue has completely flowed out, the container can be replaced to collect the cooking oil.
[0030] The above shows and describes the basic principles, main features and advantages of the present invention. The various components mentioned in the present invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in this utility model is defined by the appended claims and their equivalents.
