Description

Technical Field

[0001] The utility model relates to a boiling tank for overcoming caking of high-viscosity powder slurry and its fully automated production line, belonging to the field of food processing equipment. Background Technique

[0002] After the millet is broken and ground, when it is boiled in an ordinary stainless steel frying pan on a microcrystalline flat electric furnace, with the heating and cooling of the electric furnace and the temperature difference change of the slurry in the pot up and down, left and right, caking phenomenon occurs rapidly at the bottom of the millet slurry. Although a special person uses a scraper and bottom scraping stirring to eliminate the large-area caking and bottom sticking phenomenon, after 20 minutes of high-temperature boiling and stirring at 100 °C, there are still many granular hard blocks suspended in the cooked millet slurry; changing to an electric stirrer for rapid stirring only makes the granular hard blocks suspended in the millet slurry become fewer and smaller, and cannot be completely eliminated. After the temperature of the millet slurry drops, they will become harder and more solid; if they are always retained in the finished product, the dried millet slurry powder, when dissolved into a porridge-like state with hot boiling water or hot purified water during consumption, the surface of the granular hard blocks in the porridge becomes viscous, and as the temperature drops, they stick together again, which affects the dissolution of tryptophan, a sleep-aiding component in the broken-wall fine powder of millet, and reduces the sleep-aiding effect of the broken-wall millet powder; we consulted the existing food processing equipment materials and consulted relevant food equipment manufacturers, and only saw a colloid mill on page 77 of "Dairy Technology" edited by Mr. Li Xiaodong, which can be used for ultra-fine grinding of colloidal or near-colloidal materials in food; however, it cannot crush the material while heating and boiling the colloidal material. Summary of the Invention

[0003] The utility model provides a boiling tank for overcoming caking of high-viscosity powder slurry and its fully automated production line to solve the problem that the existing equipment cannot crush the material while heating and boiling the colloidal material.

[0004] To solve the above problems, a boiling tank for overcoming caking of high-viscosity powder slurry is proposed, which includes a tank body with an open upper end and an upper cover matching the upper end of the tank body. A motor is embedded in the upper cover, and the output shaft of the motor extends vertically downward into the tank body. A stirrer is arranged in the tank body, and the output shaft of the motor is detachably connected to the stirrer to drive the stirrer to rotate. Spring pressure rollers are respectively arranged along the inner wall of the tank body on both sides of the stirrer, and scrapers for scraping the powder slurry on the inner wall of the tank body are oppositely arranged on both sides of each spring pressure roller. The bottom of the stirrer also has a stirring plate that fits the inner wall of the bottom of the tank body, and a powder slurry outlet is also opened at the bottom of the tank body.

[0005] In the aforementioned boiling tank, the cross-section of the stirring plate is a cross-shaped structure, and turning blades are also arranged between adjacent two stirring plates of the cross-shaped structure for turning the powder slurry at the bottom to the spring pressure roller.

[0006] In the aforementioned boiling tank, the stirring plate is an integral cross-shaped stirring plate composed of four stirring blades. One end of the material turning blade is fixed to the stirrer, and the other end is in contact with the inner wall of the tank. The material turning blade is inclined upward from bottom to top along the circumferential direction of the tank body, so as to turn the powder slurry during the rotation of the material turning blade.

[0007] In the aforementioned boiling tank, the cross-section of the scraper is a pliers-like structure.

[0008] In the aforementioned boiling tank, the spring pressure roller includes a roller, a spring and a bearing. Bearings are respectively arranged at both ends of the roller. Chutes are respectively opened along the diameter direction of the tank body at the upper and lower ends of the stirrer where the spring pressure roller is located. The bearings at both ends of the roller are respectively slidably arranged in the upper and lower chutes, and springs are also pressed between the stirrer and the bearings in the chutes. The pressed springs push the roller to roll against the inner wall of the tank body.

[0009] In the aforementioned boiling tank, a feed inlet penetrating the upper cover is also opened on the upper cover, and a feed cover that can be opened and closed is arranged on the feed inlet.

[0010] In the aforementioned boiling tank, the tank body is a stainless steel tank integrally stretched from a stainless steel plate with a thickness of 1.5 - 2 mm. A steam heating jacket is fixedly arranged closely against the outer wall outside the tank body. The steam heating jacket is a closed annular sleeve structure, and a steam inlet nozzle and a steam outlet nozzle are respectively arranged at the upper part of one side and the lower part of the other side opposite to the steam heating jacket to be respectively connected with the steam outlet end and the steam inlet end of an externally arranged high-temperature steam generator.

[0011] In the aforementioned boiling tank, the motor is a frequency conversion driven numerical control motor. A reduction coupling is correspondingly arranged on the rotating shaft of the motor. A hole matching the motor is opened on the upper cover, and the motor is embedded and welded and fixed in the hole.

[0012] The present utility model also provides a fully automated production line combining the aforementioned boiling tank, including a wall-breaking crusher, a boiling tank, a steam coil heating type concentrator, a vacuum freeze dryer, and an automatic weighing vacuum packaging machine arranged in sequence. The discharge end of the boiling tank is docked with the feed end of the steam coil heating type concentrator so that the material after being boiled in the boiling tank is sent to the steam coil heating type concentrator. A screw pusher is arranged at the discharge end of the steam coil heating type concentrator, and the discharge end of the screw pusher is docked with the feed end of the vacuum freeze dryer so that the material processed by the steam coil heating type concentrator is sent to the vacuum freeze dryer. The discharge end of the vacuum freeze dryer is docked with the automatic weighing vacuum packaging machine, and the material processed by the vacuum freeze dryer is weighed and vacuum packaged by the automatic weighing vacuum packaging machine. The wall-breaking crusher, the boiling tank, the steam coil heating type concentrator, the screw pusher, the vacuum freeze dryer, and the automatic weighing vacuum packaging machine are respectively electrically connected to a control console.

[0013] Compared with the prior art, the boiling tank of the present utility model can crush materials while heating and boiling the colloidal materials. The spring pressure roller and the scraper with a pliers-like structure can effectively crush and scrape the lumpy powder slurry, so that the output viscous powder slurry has better dispersibility and pulverization, and the product properties are better.
