Therefore, the preparation process is further improved, so that the particles have obvious crisp taste. And in the second step, a microwave bulking machine is used as bulking equipment. As shown in fig. 1-10.

The material premixing process in the first step is as follows;

(1) firstly, mixing all corn starch with water, wherein the weight ratio of the corn starch to the water is 2:1, and preparing a starch mixture of non-Newtonian fluid; the water content of the material is 8-15%, so that the corn starch can be ensured to have enough water to be made into non-Newtonian fluid, and the rest water is added into the rest material;

In addition, the non-Newtonian fluid has a smooth surface during standing, is very favorable for quantitatively obtaining a starch mixture through the inserting cylinder, has very small error between the starch amounts obtained by the inserting operation at different positions, and is in an allowable range

(3) Inserting a hard cannula 452 from the top end of the insertion tube 441, inserting the cannula 452 into the starch mixture, pouring the protein mixture except corn starch into the cannula 452, and then withdrawing the cannula outwards to enable the protein mixture to be completely reserved in the starch mixture;

(4) the negative pressure suction is performed on the top end of the cartridge 441, and the starch mixture coated with the protein mixture is stopped in the cartridge 441, and after the cartridge 441 is pulled out of the material box 430, positive pressure is applied to the top end of the cartridge 441, so that the material is discharged onto the tray 300, and a material particle to be puffed is formed.

In order to make the crisp feel of the outer layer of the starch more obvious, the material further comprises 0.5-1 part of citric acid and 0.3-0.6 part of sodium bicarbonate, wherein the water except for the water added into the corn starch is introduced into the starch mixture through the cannula 452, and after the dry protein mixture enters the starch mixture through the cannula 452, the rest water is introduced into the dry protein mixture through the cannula 452, so that the sodium bicarbonate is decomposed to generate micro bubbles, and a large number of micro bubbles are formed in the starch mixture.

The crisp feeling is more obvious by forming micro bubbles in the starch mixture and then carrying out microwave puffing.

The equipment used in the production process comprises a microwave bulking machine 100, a conveyer belt 200, a tray 300 and a mixing device 400;

the mixing device 400 comprises a base 410, a sliding frame 420, a material box 430, a material taking assembly 440, an auxiliary material assembly 450 and a moving device 460;

the cartridge 430 is used for mixing corn starch and water to prepare a non-newtonian fluid;

the material taking assembly 440 comprises a cartridge 441, a fixing frame 442, a negative pressure tube 443 and a pressure source 444;

the plurality of the inserting cylinders 441 are vertically fixed on the fixing frame 442, and the fixing frame 442 can move up and down along the sliding rail on the sliding frame 420 through the lifting device;

the negative pressure pipe 443 is in sealing communication with the cartridge 441, the negative pressure pipe 443 is in communication with the pressure source 444, and the pressure source 444 can apply positive pressure and negative pressure into the cartridge 441;

the auxiliary material assembly 450 comprises an auxiliary material box 451 and a cannula 452;

the auxiliary material box 451 is used for spreading the protein mixture;

the insertion tubes 452 are vertically fixed on the bottom surface of the auxiliary material box 451, the insertion tubes 452 are communicated with the space in the auxiliary material box 451, the insertion tubes 452 correspond to the insertion tubes 441 one by one, and the insertion tubes 452 are coaxial with the corresponding insertion tubes 441; and after insertion of the cannula 452 into the starch mixture, the height of the protein mixture within the cannula 452 is less than the height of the starch mixture;

the bottom end of the insertion tube 452 is hinged with an end cover 4521, so that the starch mixture cannot enter the insertion tube 452 when the insertion tube 452 is inserted into the starch mixture, and the starch mixture is lifted along the insertion tube 441; end cap 4521 is made of metal and is capable of moving downwardly away from the bottom nozzle of cannula 452 under the force of gravity;

the moving device 460 is fixed on the sliding frame 420, and the moving device 460 is used for driving the auxiliary material box 451 to move up and down. The moving device 460 may also be a common lifting device such as an electric telescopic rod, an air cylinder, an oil cylinder, etc.

The auxiliary material assembly 450 further comprises a hopper 453 and a tray 454;

the top opening of the hopper 453 is square, the bottom opening is communicated with the insertion pipes 452, and the hoppers 453 are in one-to-one correspondence with the insertion pipes 452; the top edges of the top openings of adjacent hoppers 453 are overlapped, and all the top openings form a finished rectangle;

the tray 454 comprises a positioning shaft 4541 and a movable plate 4542; the two axial ends of the positioning shaft 4541 are fixed on the side wall of the auxiliary material box 451, the positioning shaft 4541 is provided with a plurality of pieces, and the number of the positioning shafts is the same as the number of rows of the hoppers 453; the axis of the positioning shaft 4541 is positioned right above one side of a rectangle formed by a row of corresponding top openings, one side of the movable plate 4542 is rotationally connected with one positioning shaft 4541, the other side is magnetically attracted on the adjacent positioning shaft 4541, the positioning shaft 4541 is provided with an electromagnet, and the electromagnet can absorb the vacant side of the adjacent movable plate 4542 when being electrified; all the movable plates 4542 are magnetically attracted on the positioning shaft 4541 to form a flat surface of the protein material; when the electromagnet on the positioning shaft 4541 is de-energized, the movable plate 4542 rotates under the force of gravity, causing the tiled material to fall into the corresponding hopper 453.

In actual use, starch and water are mixed in the material box 430 to prepare non-newtonian fluid, and then the lifting device is controlled to drive the fixing frame 442 to move downwards and insert into the starch mixture until the starch mixture is found on the bottom surface of the material box 430. The rate of insertion can be adapted to the actual material so that the insertion is not too fast or too slow. Too fast insertion, too slow starch, because of its tackiness, can result in the starch sagging as the cartridge 441 contacts the starch mixture, but less starch mixture actually enters the cartridge. At a suitable rate, the starch mixture can be inserted with a small deformation, like "tofu", so that the amount of material taken can be substantially constant.

Thereafter, the cannula 452 is controlled by the movement device 460 to slowly move downward and the end cap 4521 is prevented from rotating to close the cannula 452 when contacting the starch mixture. Insertion of the cannula 452 creates a cavity within the starch mixture, and the cannula 452 does not bottom out, facilitating subsequent coating of the starch mixture within the cannula 452 with the protein mixture. After the cannula 452 is moved into place, the electromagnet is energized by spreading the protein mixture at the tray 454. The electromagnet is then de-energized, causing the movable plate 4542 to rotate out of the magnetically attracted state to allow an equal amount of protein mixture to enter the cannula 452. After 10-20 seconds of rest, the end cap 4521 will open under the force of gravity and then the cannula 452 will be slowly withdrawn by the moving means 460, whereupon the material in the cannula will remain in the starch mixture.

If water is required, the cannula 452 is about to be detached from the starch mixture and the internal dry material is left completely in the starch mixture. And then the movable plate 4542 is adsorbed on the positioning shaft, after water is poured in, the water surface is leveled, the electromagnet power supply is disconnected, so that water uniformly enters each insertion pipe 452, and then the insertion pipes 452 are quickly pulled out, so that the water, citric acid and sodium bicarbonate are contacted in the starch mixture.

Of course, sodium bicarbonate can be mixed with the starch mixture first, citric acid is included in the dry protein mixture, and after water is added, the citric acid contacts the sodium bicarbonate in the starch mixture, creating a large number of bubbles in the starch mixture as shown in fig. 10. Then microwave puffing is carried out, and the prepared particles are crisp and have better mouthfeel. The internal protein mixture absorbs part of water and then is bonded into clusters, and is matched with the internal cereal powder to carry out a certain amount of puffing, so that the outer layer is crisp, the internal is not very hard, and the taste is layered. A very hard overall particle is not formed.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
