  • twin-screw extrusion instead of the traditional single-screw extrusion makes the filaments uniform and clear, which is conducive to continuous loosening and automatic quantification; the heating temperature is always kept slightly below 100 ° C, so that the rice flour can be made Fully matured, the temperature can be kept constant within the required temperature range, so that the extruded rice fans are of good quality; the steam heating during the extrusion molding and the friction heating of the powder paddle and the screw make the slurry fully mature, fully satisfying the convenient rice noodles
  • the maturation requirements do not require secondary re-steaming, which greatly simplifies the process and saves energy, while saving equipment costs.
  • the freezing temperature is generally 15° (:.
  • Quantitative cutting process The length of each fan is selected according to the required weight of the rice flour after the loosening, and the continuous loose powder strip is quantitatively cut by the quantitative cutting machine, and controlled by the swinging mechanism through the electronic automatic synchronous tracking system. , accurately distribute each fan to the drying toner box.
  • High-pressure dehydration process The air ducts of the two rows of the plastic dehumidifier arranged at different positions of the conveyor belt are respectively blown to the four side walls of each powder block in the drying box to destroy the water film on the wall of the drying box. Prevent the water film from blocking the hole in the glow box, allowing water to leak from the hole in the drying box.
  • the fan group in the dry box is forcedly dehydrated by the air cylinder in time, so that the fan group is loose and easy to dry, so that the dried powder block is convenient for brewing and ready to eat, shortening the drying time, and reducing energy efficiency.
  • the dehydrated powder block is pre-dried and dehumidified by a radiator and a circulating fan, so that the wet fans are at a temperature of 50 X to 90 ° C, and the relative humidity is less than 70%.
  • Powder block drying The pre-dried and dehumidified powder blocks are placed in a drying chamber for drying for 150 to 180 minutes, and then sent to the powder block cooler through the tail of the dryer.
  • Powder block air-cooling process The powder from the dryer has a higher temperature, and is cooled by an air-cooler for more than 2 minutes, so that the temperature of the powder block after cooling is close to room temperature (or 5 ⁇ 10° above room temperature). C), for safe packaging and storage.
  • Packaging and conveying process The powder block is sent from two outlets of the split conveyor to two packaging conveyors.
  • Packaging process It is sent to the packaging machine by the packaging conveyor for product packaging.
