Description

TECHNICAL FIELD

[0001] The present application relates to the field of sterilization equipment, in particular to a high-temperature sterilization equipment for rice powder. BACKGROUND

[0002] The sterilization kettle is a kind of equipment for sterilizing cooked food through high pressure and high temperature. According to the structure, it can be divided into double-layer water bath type sterilization kettle, left-right chamber sterilization kettle and double-layer left-right chamber sterilization kettle. The double-layer water bath type sterilization kettle is one of the most commonly used sterilization equipment in food processing plants. The double-layer water bath type sterilization kettle is composed of two independent and interconnected tanks. The upper tank is mainly used for preheating and storing water, and the lower tank is a sterilization tank. When the double-layer water bath type sterilization kettle is used to sterilize rice powder, water is first added to the upper tank until the water level reaches 90%. Then the steam generator is started to heat the water in the upper tank until the preset temperature is reached. In this process, the packaged rice powder is placed in the placing rack and pushed into the lower tank for sterilization. When the temperature of the upper tank reaches the preset value, the lower tank is first pressurized until it reaches the preset value. Then the hot water in the upper tank is put into the interlayer of the lower tank. The lower tank is heated by the heat transfer of the hot water in the interlayer, thereby achieving sterilization of the rice powder in the placing rack. After the sterilization is completed, the program automatically starts to pump the water in the interlayer of the lower tank back to the upper tank for storage and heat preservation for the next sterilization. When the hot water in the interlayer of the lower tank is completely pumped back to the upper tank, the water pump is used to send cold water into the interlayer of the lower tank to cool the lower tank. When the temperature in the lower tank drops to the set value, the rice powder in the lower tank is taken out.

[0003] In the prior art, the rice powder placing rack is generally a conventional square rack. After the rice powder is placed, the rice powder near the outside is closer to the inner wall of the lower tank, resulting in more heat absorption. The temperature decreases after passing through the outer rice powder, further reducing the heat absorption of the inner rice powder, resulting in uneven heat absorption. SUMMARY

[0004] The present application aims to provide a high-temperature sterilization equipment for rice powder to improve the uniformity of heat absorption of rice powder in the lower tank.

[0005] The high-temperature sterilization equipment for rice powder in the present application comprises a double-layer water bath type sterilization kettle and a storage cylinder for placing rice powder. The top of the storage cylinder is provided with a feeding port. A sleeve is arranged in the storage cylinder and coaxial with the storage cylinder. The top of the sleeve is provided with a notch directly below the feeding port. A chain plate conveying mechanism is arranged in the sleeve. The chain plate conveying mechanism comprises a chain plate mounted on the sleeve. Push plates are uniformly arranged on one side of the chain plate away from the sleeve.

[0006] The working principle and beneficial effects of the present scheme are as follows: in use, the bagged rice flour is put into the storage cylinder through the feeding port, and when the hot water in the lower jar heats the rice flour in the jar for a period of time, the chain plate conveying mechanism is controlled to work, the chain plate conveyor drives the chain plate transmission, and since the chain plate has a push plate, the push plate drives the rice flour transmission, the rice flour in the sleeve (i.e. the rice flour in the middle position) is conveyed between the sleeve and the storage cylinder (i.e. the rice flour in the middle position is conveyed to a position close to the inner wall of the lower storage cylinder), and the rice flour originally between the storage cylinder and the sleeve is conveyed into the sleeve, thereby ensuring that the rice flour at each position is heated more evenly.

[0007] Further, the outer bottom of the storage cylinder is provided with a roller. Through the arrangement of the roller, the storage cylinder is conveniently pushed into the lower jar.

[0008] Further, the free end of the push plate between the sleeve and the storage cylinder is 1-2 cm away from the inner wall of the storage cylinder. This distance helps to reduce the material of the push plate on the one hand, and on the other hand, to avoid the rice flour being stuck between the two.

[0009] Further, the free end of the push plate is provided with a chamfer. Avoid the free end of the push plate hanging on the rice flour.

[0010] Further, the notch is equal in length to the sleeve and consistent in length direction.

[0011] Further, the storage cylinder is coaxial with the lower jar. This helps to improve the heating uniformity of the rice flour. BRIEF DESCRIPTION OF DRAWINGS

[0014] The following will be further described in detail through specific embodiments:

[0015] The reference signs in the drawings of the specification include: upper jar 1, steam inlet pipe 2, lower jar 3, water pump 4, roller 5, storage cylinder 6, feeding port 7, sleeve 8, chain plate 9, push plate 10, support rod 11.

[0016] The embodiments are basically as shown in the accompanying drawings Figures 1-2As shown: A high-temperature sterilization device for rice noodles includes a double-layer water bath sterilizer, a storage cylinder 6, and an adjustment component located inside the storage cylinder 6. The double-layer water bath sterilizer includes an upper tank 1 and a lower tank 3 that are connected. Since the double-layer water bath sterilizer in this application uses existing technology, its specific structure will not be described in detail here. A feeding port 7 is provided at the top of the storage cylinder 6. The adjustment component includes a sleeve 8 and a chain conveyor mechanism. The sleeve 8 is fixedly connected inside the storage cylinder 6, and the two are coaxial. A notch is provided at the top of the sleeve 8, and the notch is perpendicular to the length of the sleeve 8. The direction and length are consistent, and the notch is located directly below the feeding port 7; the bottom of the storage cylinder 6 is provided with a support rod 11, and the support rod 11 is provided with a roller 5; the chain plate conveying mechanism includes a chain plate 9 and a motor that drives its transmission. The motor is installed on the outer wall of the storage cylinder 6, the chain plate 9 is installed on the sleeve 8, and push plates 10 are evenly distributed on the side of the chain plate 9 away from the sleeve 8. The free end of the push plate 10 is chamfered, and the free end of the push plate 10 between the sleeve 8 and the storage cylinder 6 is 1-2 cm away from the inner wall of the storage cylinder 6; the installation of the chain plate conveying mechanism in this application adopts conventional technology.

[0017] The specific implementation process is as follows: During use, steam enters the upper tank 1 through the steam inlet pipe 2, heating the water inside the upper tank 1 until it reaches the preset temperature. Simultaneously, bagged rice noodles are placed into the storage cylinder 6 through the feeding port 7. After the rice noodles are added, the storage cylinder 6 is pushed into the lower tank 3 by rollers 5. Once the temperature of the upper tank 1 reaches the preset value, the lower tank 3 is pressurized until it reaches the preset value. Then, the hot water from the upper tank 1 is placed into the jacket of the lower tank 3. The lower tank 3 heats up due to the heat transfer from the hot water in the jacket, thus sterilizing the rice noodles. After the hot water in the tank 3 heats the rice noodles in the tank for a period of time, the motor drives the chain conveyor mechanism to work. The chain conveyor mechanism drives the chain plate 9 to drive. Since there is a push plate 10 on the chain plate 9, the push plate 10 drives the rice noodles to drive. The rice noodles located in the sleeve 8 (i.e., the rice noodles in the middle position) are conveyed to the space between the sleeve 8 and the storage cylinder 6 (that is, the rice noodles in the middle position are conveyed to the position close to the inner wall of the lower storage cylinder 6). The rice noodles that were originally located between the storage cylinder 6 and the sleeve 8 are conveyed into the sleeve 8, thereby ensuring that the rice noodles in each position are heated more evenly. After sterilization is completed, the program starts automatically, controlling the water pump 4 to pump the water in the interlayer of the lower tank 3 back to the upper tank 1 for storage and insulation in preparation for the next sterilization. After the hot water in the interlayer of the lower tank 3 is completely pumped back to the upper tank 1, the water pump 4 sends cold water into the interlayer of the lower tank 3 to cool it down. After the temperature in the lower tank 3 drops to the set value, the rice noodles in the lower tank 3 are taken out.

[0018] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
