Description

Fully automatic convenient instant rice noodle production line and production process thereof

The invention relates to a processing device for convenient instant rice noodles and a production process thereof, in particular to a fully automatic ready-to-eat instant instant rice flour processing device and a production process thereof. Background technique

Convenient instant rice noodles have the advantage of being convenient to eat and are very popular. The existing convenient instant rice noodle production process is manual or semi-manual semi-automatic production. There are two production processes. One process includes: rice transportation, one meter polishing, specific gravity, sand removal, one jet, one meter, one meter of water separation. Grinding sieve filter, vacuum dehydration, one time delay, one feed, starch, cooking, stirring, one powder, one squeeze, one powder, one powder, one high pressure, one fan, one steaming, one fan, cooling, aging, one artificial silk, one cut, one box Finishing a dehydration and drying a powder block and air-cooling into a bag. There are also technicians who propose the second dry process production, namely: rice transporting a meter of polishing, a specific gravity, sand removal, a jet, washing rice, water, rice, separation, a wet rice, crushing, adding starch, cooking, stirring, making a powder, a piece of flour, and a powder. Conveying a high-pressure extrusion wire, a fan re-steaming, a fan, cooling, aging, a piece of artificial silk, cutting off a box, finishing a dehydration, drying a powder block, and cooling the package into a bag. - The production of rice flour in both of the above processes is in the form of secondary cooking, that is, a process requiring two heating cycles. Why do you need two heating? The reason is that the once-extruded fully cooked rice flour is very viscous and mutually adhered to each other, and the existing method cannot achieve better separation. Only in this way, in the production process of rice flour, the first cooking is not cooked, so that the extruded rice fans are semi-cooked, the viscosity is lower, and there is no hard-to-separate adhesion between them. . The extruded rice vermicelli is then cooked again to bring it to a fully cooked state. Due to the two cooking times of the picking, two heatings are required, which consumes a lot of energy. If it can be changed to one cooking--, it will effectively reduce the energy consumption. It has great value in the current energy-saving and source-saving situation. However, because the viscosity problem of rice flour cannot be solved, it has become an unsolvable problem.

In addition, because the existing rice noodle production uses manual or semi-manual semi-automatic production, manual transfer, and natural drying conditions, the hygienic conditions of the working environment are insufficient, and the requirements of food hygiene in advanced countries cannot be met. The production process and equipment of rice flour can fully realize automatic production and meet the strict requirements of food hygiene.

For the above reasons, the current production of convenient instant rice noodles, including secondary cooking and manual production, will greatly reduce production efficiency, increase energy consumption, increase production costs and equipment costs, and improve sanitary conditions. Summary of the invention

The object of the present invention is to provide a fully automatic convenient instant rice noodle production line and a production process thereof, which solve the problems of secondary cooking, automatic production, poor sanitary conditions, etc. in the rice flour production process, and improve production efficiency.

The invention process is further described in detail below in conjunction with the production process:

Rice treatment of earth and earth: Through the rice processing device, the rice is processed by the initial processing to facilitate the subsequent processing. The rice processing technology can be either wet processing or dry processing. However, from the viewpoint of energy saving, it is better to use dry processing, that is, rice processing, rice transportation, rice polishing, rice specific gravity sand removal, The process of jet washing, water meter separation, and wet rice pulverization.

Cooking and stirring to beat rice: Mixing rice flour and starch according to the formula amount and cooking to achieve the requirements of powder processing, feeding the powder into the extrusion device, and extruding the powder into a powder strip, and the self-cooking extruder The extruded vermicelli is sent to a self-cooking extruder.

Self-cooking and extruding process: The powder strips are respectively fed into the inlet of the self-cooking extruder, and the powder strips are heated and powdered by the self-cooking extruder. The frictional heating of the strip and the screw causes the strip to be fully cooked and extruded. The use of 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.

Rice noodle freezing process: After the extruded fans enter the rice fan freezer, the freezing time is generally

For 2 hours, the freezing temperature is generally 15° (:.

Continuously loosening process: The fans who complete the aging process are automatically fed into the continuous wire-cutting machine, and the fans are loosely and clearly separated by automatic continuous loosening.

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. Before drying, 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.

- Pre-drying and dehumidification process: 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.
