[0002] Bean snacks need to be pre-gelatinized before frying. In the prior art, steam is generally used for heating to achieve pre-gelatinization. This method will cause the moisture content of the intermediate material after pre-gelatinization to increase. In subsequent frying, it is often necessary to increase the frying time or increase the frying temperature, which is not conducive to improving the quality of the final product.

[0003] The present invention intends to achieve pre-gelatinization by pressure pre-frying. Pre-gelatinization under pressure can make the product more crispy and have better sensory properties.

A window for observing the oil amount is provided on the tank, so that the amount of oil can be clearly observed. However, this pressurized tank generally has an electric heating device inside the tank to directly heat the edible oil. During pre-frying, the material will be in direct contact with the electric heating device, which may cause the material to be overheated and burnt. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a pre-gelatinization tank, which solves the problem in the prior art that direct heating in the tank body causes excessive heating of materials and causes scorching.

[0007] In the above embodiment, materials and edible oil are introduced into the inner tank body through the first feed pipe and the second feed pipe respectively, and a heating medium is introduced into the cavity through the liquid inlet pipe. The heating medium heats the inner tank body, and indirectly heats the edible oil in the inner tank body to achieve pre-frying of the materials. After the pre-frying is completed, the materials together with the edible oil are discharged from the discharge pipe below and enter the subsequent process.

[0008] Furthermore, the installation tube is surrounded by a top plate, two side plates and a bottom plate, wherein the bottom plate is arranged obliquely and a higher end thereof is fixedly connected to the outer tank body, and the other end thereof is fixedly connected to the inner tank body.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] like Figure 1 , 2As shown, this embodiment provides a pre-gelatinization tank, which includes an outer tank body 1 and an inner tank body 2 fixedly connected to the outer tank body 1, the inner tank body 2 and the upper and lower ends of the outer tank body 1 are connected to form an annular cavity 3 therebetween, the upper end of the outer tank body 1 is covered with a tank cover 4 that closes the inner tank body 2, the tank cover 4 is provided with a first feed pipe 5 (for introducing materials, such as broad beans and soybeans), a second feed pipe 6 (for introducing frying oil, i.e., edible oil) and an air inlet pipe 7 (connected to an external air compressor for providing pressure to the inner tank body 2), the bottom and upper end of the outer tank body 1 are respectively provided with a liquid inlet pipe 8 and a liquid outlet pipe 9 connected to the cavity 3, and the bottom of the outer tank body 1 is also fixedly connected with a discharge pipe 10 connected to the bottom of the inner tank body 2;

[0029] The pre-gelatinization tank also includes a mounting tube fixedly connected to both the outer tank body 1 and the inner tank body 2 and communicated with the inner tank body 2, wherein one end of the mounting tube connected to the outer tank body 1 is fixedly connected to a high-temperature resistant glass 11, a through hole is provided on the outer tank body 1 and the high-temperature resistant glass 11 is located in the through hole, wherein a hollow floating part 12 capable of moving vertically up and down is provided in the mounting tube.

[0030] In the above embodiment, the material and edible oil are introduced into the inner tank body 2 through the first feed pipe 5 and the second feed pipe 6 respectively, and the heating medium is introduced into the cavity 3 through the liquid inlet pipe 8. The heating medium heats the inner tank body 2 and indirectly heats the edible oil in the inner tank body 2 to achieve pre-frying of the material. After the pre-frying is completed, the material and the edible oil are discharged from the discharge pipe 10 below and enter the subsequent process (i.e., the frying process). In this embodiment, the inner tank body 2 is arranged in the outer tank body 1, and the heating medium is introduced into the cavity 3 between the two to indirectly heat the edible oil and the material, thereby effectively avoiding direct contact between the heating medium and the raw material, and preventing the problem of overheating caused by direct contact between the material and the heating source; further, this embodiment adopts pre-frying to achieve pre-gelatinization to avoid changes in the moisture content of the intermediate; specifically,

[0031] When pre-gelatinization is performed, edible oil is first introduced into the inner tank body 2, and then pressurized into the inner tank body 2 through the air inlet pipe 7, and a heating medium is introduced from the liquid inlet pipe 8 to heat the edible oil, and then the material is introduced into the inner tank body 2 for pre-frying. After completion, the pressure is relieved through the air outlet pipe 13 (a pressure relief valve is installed on the air outlet pipe 13) arranged on the outer tank body 1 and connected to the inner tank body 2 (and connected to the outside world). After the pressure relief is completed, the edible oil is discharged from the discharge pipe 10 together with the material to complete the pre-gelatinization, wherein the heating medium is oil or water vapor heated to the required temperature in advance. During the pre-gelatinization process, the heating medium continues to enter from the liquid inlet pipe 8 and is then discharged from the upper liquid outlet pipe 9 to ensure the required temperature for pre-gelatinization.

[0032] like Figure 1 , 3 As shown, further, the hollow floating member 12 provided in the present embodiment is used to assist in observing the liquid level of the edible oil. Specifically, during pre-gelatinization, it is necessary to ensure the amount of edible oil in the inner tank body 2. The hollow floating member 12 is floated on the liquid surface and can be observed through the high temperature resistant glass 11 outside the outer tank body 1. Different from the prior art, the hollow floating member 12 is easier, more convenient and quicker than the prior art to directly observe the liquid surface.

[0033] like Figure 1 , 3 As shown, the installation cylinder is surrounded by a top plate 14, two side plates 15 and a bottom plate 16, wherein the bottom plate 16 is tilted and a higher end is fixedly connected to the outer tank body 1, and the other end is fixedly connected to the inner tank body 2. The installation cylinder separates the inner tank body 2 and the cavity 3 to prevent the heating medium from mixing into the inner tank body 2. At the same time, the bottom plate 16 is tilted, and the residues and a small amount of materials entering the installation cylinder can slide down smoothly as the edible oil level drops, thereby effectively preventing materials and residues from remaining in the installation cylinder during frying.

[0034] like Figure 3 As shown, a receiving groove 17 extending into the cavity 3 is fixedly connected to the top plate 14, a vertical guide slide bar 18 is fixedly connected to the receiving groove 17, and the hollow floating member 12 is slidably connected to the guide slide bar 18 and the hollow floating member 12 can be accommodated in the receiving groove 17. The provided guide slide bar 18 can ensure that the hollow floating member 12 rises vertically with the liquid level, and the provided receiving groove 17 enables the lower surface of the hollow floating member 12 to rise to the upper edge of the high temperature resistant glass 11, thereby making the observation range larger, in particular, so that the volume of the hollow floating member 12 can be larger, the buoyancy is greater, and it is easier to float up with the rise of the liquid level, and the hollow floating member 12 can smoothly enter or exit the receiving groove 17 under the guidance of the guide slide bar 18.

[0035] Specifically, Figure 3 As shown, the hollow floating member 12 includes a box body 19 and a sliding tube 20 fixedly connected to the top and bottom of the box body 19. The sliding tube 20 is slidably mounted outside the guide slide rod 18, that is, the guide slide rod 18 slides in the sliding tube 20. When the liquid level rises or falls, the box body 19 floats up or moves down due to the buoyancy, thereby realizing the position indicating function.

[0036] like Figure 4 , 5As shown, the lower end of the box body 19 is also fixedly connected with a guide box 21 that is in sliding contact with the heat-resistant glass 11. When the box body 19 is at the lowest position, the guide box 21 abuts against the bottom plate 16. Specifically, the heat-resistant glass 11 is an arc-shaped structure, and the guide box 21 also has a surface that is an arc-shaped structure (i.e., a surface that contacts the heat-resistant glass 11). The setting of the guide box 21 enables the hollow floating member 12 to add a sliding guide between the guide box 21 and the heat-resistant glass 11 on the basis of the guide slide bar 18, thereby making the hollow floating member 12 more stable. At the same time, this can also ensure that the hollow floating member 12 does not separate from the guide slide bar 18; more importantly, the box body 19 and the guide box 21 both have a certain thickness, and the guide box 21 is also connected to the box body 19, so that it is not easy for debris and materials to adhere to the hollow floating member 12, so as to ensure that the debris and materials will not remain in the installation tube.

[0037] Furthermore, if Figure 3 As shown, in order to prevent the material from entering the mounting cylinder during pre-gelatinization, the top plate 14 is also fixedly connected to a filter plate 22, and one end of the filter plate 22 away from the top plate 14 extends downward and is separated from the bottom plate 16. The filter plate 22 is also fixedly connected to the two side plates 15, and the hollow floating member 12 is located between the filter plate 22 and the high temperature resistant glass 11. The filter plate 22 is provided with filter holes with small apertures to prevent the material and most of the debris from passing through the filter plate 22. At the same time, a certain distance is left between the lower edge of the filter plate 22 and the bottom plate 16, and the distance is smaller than the particle size of the material (the filter hole is also smaller than the particle size of the material), so as to prevent the material from entering the installation cylinder, and the edible oil from entering the installation cylinder without being blocked, thereby ensuring the normal function of the hollow floating member 12; specifically, this can effectively prevent the material from entering the installation cylinder and causing adverse effects on the hollow floating member 12, but a small amount of residue with small particle size will still pass through the filter plate 22 and enter, and the gap provided below can ensure that these residues exit the installation cylinder as the liquid level drops, thereby ensuring that no residues remain in the installation cylinder.

[0038] like Figure 1 , 2 As shown, in order to facilitate observation of the pressure in the inner tank body 2, a pressure gauge 23 is also connected to the tank cover 4; at the same time, in order to facilitate observation of the temperature of the heating medium in the cavity 3, a temperature gauge 24 for measuring the temperature of the heating medium in the cavity 3 is also connected to the outer tank body 1.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
