[0018] Specifically, a manhole cover 3 is provided at the upper end of the sterilization tank body 14, and the top of the manhole cover 3 extends to the outside of the insulation cabin 18. The manhole cover refers to a general term for a cover plate and its fixing accessories installed on the manhole with sealing performance. The manhole cover can be divided into a protruding type and a buried type according to whether it is higher than the opening surface after installation. The utility model adopts a protruding manhole cover. The cover plate, enclosure and seat ring of the manhole cover are usually made of hot-rolled carbon steel or the same material as the main structure used to install the manhole cover. The gasket and handle are made of ordinary carbon cable steel: the sealing gasket is made of flame retardant and water-resistant rubber, the bolts or studs are made of stainless steel or carbon steel, the nuts are made of carbon steel, stainless steel or brass, and the bolts, studs, nuts and washers made of carbon steel are all galvanized.

[0019] Specifically, both the front and rear ends of the sterilization tank body 14 are provided with sealed bearing seats 15 , and the sealed bearing seats 15 are fixed in the side walls of the heat preservation cabin body 18 .

[0020] Specifically, a feed port 4 is provided at the upper end of the sterilization tank body 14, and a feed screw conveyor 6 is provided at the upper end of the feed port 4. The discharge end of the feed screw conveyor 6 is connected to the feed port 4, and a feed valve 9 is provided between the feed port 4 and the sterilization tank body 14. A screw conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of transportation. The screw conveyor can transport horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, etc. In terms of conveying form, it is divided into a shaft screw conveyor and a shaftless screw conveyor, and in terms of appearance, it is divided into a U-shaped screw conveyor and a tubular screw conveyor. In the utility model, the feed screw conveyor 6 and the discharge screw conveyor 13 both adopt horizontal, shafted tubular screw conveyors. When materials are added to a fixed When the material is in the machine trough, due to the gravity of the material and the friction between it and the machine trough, the material accumulated in the lower part of the machine trough does not rotate with the spiral body, but only moves forward under the push of the rotating spiral blades, just like a non-rotating nut moving translationally along the rotating screw, thereby achieving the purpose of conveying materials. The machine is convenient for multi-point loading and unloading, and can simultaneously complete mixing, stirring or cooling functions during the conveying process. The horizontal screw conveyor has a simple structure, is easy to install, maintain and troubleshoot, and is suitable for horizontal or slightly inclined continuous and uniform conveying of loose materials. The working environment temperature is -20~+40℃, and the conveying material temperature is -20~+80℃. Its rotation speed is lower than that of the vertical conveyor. It is mainly used for horizontal or small angle conveying of materials, and the conveying distance is not more than 70 meters.

[0021] Specifically, a spray pipe is provided in the cavity of the insulation cabin 18, and the water inlet end of the spray pipe extends to the outside of the insulation cabin 18 and is connected to a booster water pump 5. A water tank 2 is provided at the water inlet end of the booster water pump 5. The main working principle of the booster water pump 5 is to first open the screw plug, and pour the water in the water tank 2 into the suction chamber through the water filling port, and then start the centrifugal pump. The impeller rotates rapidly, and the blades of the impeller drive the liquid to rotate. When the liquid rotates, it relies on inertia to flow to the outer edge of the impeller. At the same time, the impeller sucks liquid from the suction chamber. In this process, the liquid in the impeller flows around the blades. In the circumferential motion, the liquid acts a lift on the blades. In turn, the blades act on the liquid with a force equal to and opposite to the lift. This force does work on the liquid, so that the liquid gains energy and flows out of the impeller. At this time, the kinetic energy and pressure energy of the liquid are increased, achieving the effect of boosting the water flow sprayed from the spray pipe.

[0022] Specifically, a hot air valve 11 is provided on the wall of the thermal insulation cabin 18, and a circulating high-pressure hot air blower 8 is provided at the air inlet end of the hot air valve 11. The circulating high-pressure hot air blower 8 consists of three major parts: a blower, a heater, and a control circuit. After the high-pressure hot air blower is energized, the blower blows air into the heater, allowing the air to pass evenly through the inside and outside of the spiral heating wire. The heat generated after the heating wire is energized is heat exchanged with the cold air passing through, thereby increasing the wind temperature at the air outlet. The K-type thermocouple at the air outlet promptly feeds back the detected air outlet temperature to the temperature controller. The instrument monitors the actual working temperature according to the set temperature, and transmits the relevant information back to the solid-state relay to control whether the heater is working. At the same time, the blower can use the air volume regulator, that is, the frequency converter and the air door to adjust the air volume of the blown air, thereby realizing the regulation of the working temperature and air volume. In addition, the hot air blower is also provided with an over-temperature protection circuit for the fan air inlet and the motor, and an emergency brake switch for the main circuit, so as to further improve the protection of the equipment.

[0023] Working principle: When the utility model is working, after sterilization is completed, the steam inlet valve 20 is opened to exhaust the steam in the sterilization tank 14, and cooling begins. The vacuum valve 10 and the vacuum pump 12 are opened to vacuum and cool the sterilization tank 14. At the same time, the booster water pump 5 is turned on, and the surface of the sterilization tank 14 is sprayed and cooled through the spray pipe connected thereto. When the temperature drops to 20-30 degrees, the cooling is completed, and the vacuum valve 10 and the booster water pump 5 are closed. After cooling, the discharge valve 17 is opened, and the discharge amount is controlled by adjusting the rotation speed. The sterilized raw materials are transported to the purification area for standby use through the discharge screw conveyor 13 arranged in the lower bin.
