[0026] The present invention provides a mixed hot slurry pulping machine for making wet slurry rice noodles, including a stirring barrel 1, a feeding mechanism 2, a hot water supply mechanism 3, a stirring mechanism 4 and a housing 5. The stirring barrel 1 is arranged inside the housing 5. The housing 5 is a box with a hollow interior and a top that can be lifted. The feeding mechanism 2, the hot water supply mechanism 3 and the stirring mechanism 4 are respectively arranged on the top of the housing 5 and all have extending parts passing through the top of the housing 5 and communicating with the stirring barrel 1;

[0027] The stirring mechanism 4 includes a stirring motor 11 and a stirring rod 12. The stirring motor 11 is movably connected to the stirring rod 12. The stirring rod 12 is vertically arranged on the center line of the stirring barrel 1, and a stirring head is detachably connected to the end of the stirring rod 12.

[0028] A plurality of groups of screws are arranged outside the stirring barrel 1 and connected to the housing 5, and a weight sensor is installed at the bottom of each group of screws.

[0029] The feeding mechanism 2 is arranged in the shape of a square funnel, with a foldable closing opening at the top and is communicated with the inside of the stirring barrel 1 at the bottom.

[0030] The outer layer of the stirring barrel 1 is provided with a heat-insulating material, and a thermal resistance heater 13 is arranged at the center of the bottom.

[0031] The hot mixed slurry pulping machine further includes a sewage discharge valve 6 and a slurry supply pump 7. The sewage discharge valve 6 and the slurry supply pump 7 are both arranged at the bottom of the stirring barrel 1 and are respectively provided with pipelines communicated with the outside of the housing 5.

[0032] The hot mixed slurry pulping machine further includes a control box 8. The control box 8 is electrically connected to the stirring barrel 1, the feeding mechanism 2, the hot water supply mechanism 3 and the stirring mechanism 4.

[0033] The hot mixed slurry pulping machine for making wet rice noodles is controlled by an embedded control system and works according to the designed technological process. Among them, the temperature control of hot water and boiling water adopts the PID algorithm for precise control.

[0034] In this embodiment, the stirring barrel 1 is a container for making and reacting rice slurry. Raw rice powder and edible water are put in through the hot water supply mechanism 3 and the feeding mechanism 2. The stirring mechanism 4 is started, and the stirring rod 12 drives the solution to continuously stir and heat in the stirring barrel 1 to form a semi-finished hot rice slurry. At this time, a certain amount of boiling water is sprayed in through the hot water supply mechanism 3, and stirring continues during the spraying process to promote the generation of rice slurry gel, and a uniformly suspended prefabricated rice slurry with a low degree of gelatinization can be obtained.

[0035] The prefabricated rice slurry after production can be directly transported to the feeding funnel of the rice noodle machine through the slurry supply pump 7. When the equipment needs to be cleaned, the sewage discharge valve 6 can also be opened to cooperate with the hot water supply mechanism 3 for flushing and discharging.

The weight sensor at the bottom of the stirring barrel 1 collects weight information, which is convenient for the user to control the quantity of raw materials input and the water inflow.

[0037] Furthermore, the present invention also provides a method for preparing mixed hot slurry for making wet slurry rice noodles. Using the mixed hot slurry pulping machine for making wet slurry rice noodles, the method comprises the following steps:

[0038] Step 1: Use the hot water supply mechanism 3 to inject a certain amount of edible hot water into the stirring barrel 1;

[0039] Step 2: Turn on the stirring mechanism 4 for continuous stirring;

[0040] Step 3: Put X kilograms of rice powder into the feeding mechanism 2;

[0041] Step 4: Turn on the heater 13 of the stirring barrel 1 to heat the water in the barrel to 70 °C and maintain the water temperature;

[0042] Step 5: The hot water supply mechanism 3 sprays a certain amount of boiling water;

[0043] Step 6: Stir until a uniformly suspended solution is formed to obtain a prefabricated rice slurry with a low degree of gelatinization.

[0044] In summary, the present invention has the following advantages:

[0045] 1. Higher production efficiency. Starting from heating the slurry (or water) to the completion of slurry preparation, under the condition of using the electric heating method, it can be completed within 5 minutes.

[0046] For the existing rice noodle production methods, in order to achieve complete cooking of the rice noodles, a secondary cooking method needs to be adopted. The traditional method is to put the rice noodle strips into a boiling water pot in batches and cook for about 2 minutes in turn; in the factory method, after the noodles are extruded, they enter the steam tunnel one after another, and are steam-heated for about 3 minutes within a specific tunnel length.

[0047] From the perspective of efficiency, whether it is the traditional method or the current factory production method, the secondary cooking time of a single batch of noodles is basically about 2 - 3 minutes, which is related to the temperature of boiling water or steam. The total amount of rice noodles cooked in this cooking method is about one kilogram every 3 minutes, while the wet slurry rice noodle raw and cooked slurry mixing production process can process the rice slurry in the entire slurry container at one time to meet the requirements. The production efficiency is greatly improved.

[0048] 2. Reduced production cost. The method and process of the present invention adopt a preheating method at a low temperature for pretreatment of the rice slurry, shortening the overall time of rice noodle production, improving production efficiency, saving energy consumption in rice noodle production, and thus reducing production costs.

[0049] 3. Improve the performance of vermicelli. The processing technology of the present invention improves the physical and chemical properties of rice slurry. The produced rice noodles are flexible, chewy, of better quality, and have the maximum degree of gelatinization. The retrogradation rate and the breakage rate are reduced to the lowest. The vermicelli has good elasticity and a flexible and chewy taste. After testing, the produced rice noodles can be repeatedly washed and soaked without breaking or making the soup cloudy; after the wet rice noodles are dried and then rehydrated or boiled again, they are not easy to break and have excellent reducibility. It is much better than most of the fresh and wet rice noodles currently on the market.

[0050] 4. The method and technology of the present invention increase the water content of rice slurry from the conventional 55% to 65%, while the quality of the produced vermicelli remains unchanged, and the flour yield is increased.

[0051] The above-disclosed are only one or more preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
