[0026] Please refer to Figures 1-4 Multi-section grain sterilization and inactivation enzyme complete equipment, including installation platform 1 and installation box 2, one side of installation box 2 is fixedly connected with air inlet pipe 3, a plurality of partition plates 4 are fixedly connected in installation box 2, discharge pipe 5 is fixedly connected on partition plate 4, electromagnetic valve is arranged on discharge pipe 5, a plurality of screw rods 6 are rotatably connected in installation box 2, one end of one of screw rod 6 is fixedly connected with stepping motor 7 fixedly connected with installation box 2 through coupling; a plurality of screw rods 6 are drivingly connected through transmission wheel and transmission belt, a plurality of electric heating rods 8 are fixedly connected in installation box 2;

[0027] Installation plate 9 is fixedly connected in installation box 2, heat recovery mechanism is arranged on the top of installation plate 9, heat recovery mechanism is used to recycle the heat in steam, drying box 10 is fixedly connected on installation platform 1, drying box 10 is connected with heat recovery mechanism, buffer bin 11 is arranged at the bottom of installation box 2, air lift 12 is arranged in buffer bin 11.

[0028] Through the grain by the installation box 2 top feed hopper into the installation box 2, while connecting with the outside steam mechanism through the air pipe 3, then the steam into the installation box 2, then by starting the stepper motor 7, stepper motor 7 drive screw rod 6 rotation, while the screw rod 6 through the transmission belt and transmission wheel drive other screw rod 6 rotation, at this time the screw rod 6 drive grain on the baffle 4 movement, then through the baffle 4 on the discharge pipe 5 discharge, thus makes the grain in the installation box 2 on the baffle 4 left and right reciprocating movement, while working with electric heating rod 8, electric heating rod 8 to the installation box 2 in the compensation heat source, realize the grain in the installation box 2 through the screw rod 6 propulsion and turnover, so that the grain is heated evenly, so as to realize the grain is fully inactivated, sterilization and enzyme, greatly improve the effect of grain inactivation, sterilization and enzyme, while the equipment automation degree is high, in the use process does not need manual operation too much, greatly improves the processing efficiency of the grain.

[0029] Example two

[0030] On the basis of example one, please refer to Figure 2 - Figure 4 As shown in the heat recovery mechanism includes the installation plate 9 fixedly connected with condenser 21, condenser 21 is fixedly connected with the water guide plate 22, the lower portion of water guide plate 22 is provided with water purification mechanism connected with installation plate 9 and installation box 2, installation box 2 is fixedly connected with the suction fan 23, one side of installation box 2 is fixedly connected with the air outlet pipe 24, one end of air outlet pipe 24 is fixedly connected with the hot hair dryer 25 fixedly connected with installation platform 1, the output end of hot hair dryer 25 is fixedly connected with the blowing pipe 26 fixedly connected with drying box 10, the top of installation plate 9 is fixedly connected with filter screen 27.

[0031] Drying box 10 is provided with a plurality of guide net plate 28, the outer surface of blowing pipe 26 is fixedly connected with a plurality of air distribution pipe 29, air distribution pipe 29 is provided with a plurality of blowing cover 290.

[0032] The bottom of guide net plate 28 is fixedly connected with vibration motor 291, the bottom of drying box 10 is provided with discharge port 292.

[0033] When the material is fully inactivated, sterilized and enzyme-killed, the material is discharged into the buffer bin 11. At this time, the suction fan 23 is working, and the suction fan 23 absorbs the steam generated during the heating of the grain through the filter screen 27 to the upper side of the mounting plate 9. At the same time, the condenser 21 is working. The hot gas passes through the condensing elbow of the condenser 21, so that the high-temperature water vapor in the hot gas is condensed into water, achieving the removal and drying of the water in the high-temperature hot gas. Subsequently, the dried hot air enters the hot air blower 25 through the air outlet pipe 24. The hot air blower 25 heats the entering hot air, and then the heated hot air enters each air distribution pipe 29 through the air outlet pipe 24. Subsequently, the air distribution pipe 29 blows air through the air distribution cover 290, and the air lifting machine 12 transports the processed grain from the buffer bin 11 to the drying box 10. Subsequently, the grain falls onto the guide net plate 28 in the drying box 10, and the vibration motor 291 on the guide net plate 28 vibrates the guide net plate 28, so that the grain flows from top to bottom on the guide net plate 28. At the same time, the grain is blown and dried by the blowing cover 290 during the flowing process, so that the remaining heat after the inactivation, sterilization and enzyme-killing of the grain is recycled and utilized, the energy consumption is reduced, and the grain after inactivation, sterilization and enzyme-killing is dried, improving the processing effect of the grain.

[0034] The problems are effectively solved.

[0035] I. The influence of microbial contamination. Cereals are extremely susceptible to contamination by molds, bacteria and yeasts during harvesting, storage and processing. When conditions are suitable, they can rapidly grow and reproduce in the grain and produce toxins, causing deterioration of cereals and their products. Therefore, measures should be taken to prevent microbial contamination and control microbial growth and reproduction during storage of cereals.

[0036] II. The influence of temperature, humidity and oxygen. Microorganisms need suitable temperature, humidity and oxygen (except for some) to grow and reproduce. For example, if the humidity is too high and the temperature is too high during the storage of rice, and the oxygen is sufficient, the contaminated microorganisms in the rice can rapidly grow and reproduce, causing the rice and its products to become moldy or spoiled.

[0037] Grains, like other organisms, are constantly undergoing respiration, which is catalyzed by oxidizing enzymes (dehydrogenases and oxidases) in the grains. Monosaccharides in the grains are constantly oxidized in the presence of oxygen, or in the absence or shortage of oxygen, to generate carbon dioxide and water, or carbon dioxide and ethanol, and release heat. The oxidation of the grains releases 26 times more heat in the presence of oxygen than in the absence of oxygen. The heat in the grain pile is increased due to the oxidation. When the humidity in the grain pile is increased by more than 15% and the temperature reaches 30°C, the activity of the oxidizing enzymes is more active, and the respiration is also intensified, so that the temperature in the grain pile is higher. Under the action of bacterial enzymes and grain hydrolytic enzymes, the organic matter in the grains is accelerated to decompose, and a foul odor occurs, and finally the grains can be completely spoiled.

[0038] Therefore, when the grains are stored, not only the water content in the grains themselves should be low (not more than 15%), but also the storage environment should be kept at low temperature, dry, and good ventilation. In order to control the oxygen content in the grain pile, some inert gases can be filled.

[0039] III. The influence of pests Pests can grow in raw grains and semi-finished products. When the warehouse room temperature is above 18°C to 21°C and the humidity is above 60%, it is suitable for the hatching and reproduction of insect eggs. When the room temperature is below 10°C, the activity of pests will be weakened. The main pests in the warehouse are beetles, mites, and moths. These pests not only damage a large amount of grains, but also make the grains have an unpleasant odor, reduce their weight, and reduce their quality. The grains are also prone to heat generation, and further action of microorganisms will cause the grains to rot and deteriorate.

[0040] In order to prevent pests from invading grains and their products, the present embodiment improves the storage conditions to prevent pests from invading, as described in the above embodiments. Traditional storage will use drug fumigation to kill pests and insect eggs when necessary. (Use high-temperature steam combined with infrared physical means to inactivate, make insect eggs protein deteriorate and inactivate, reduce and reduce the loss caused by pests in the storage process, prolong the shelf life.)
